Soul Master

   Chapter 169 Talent level beyond SSS level

   After chatting for a while, Yang Dai started to pay attention to the reality on the Internet.

   During this time, he was obsessed with expanding the yin and lacked attention to reality. The main reason was that since he cleaned up the monsters in the Xiya Mountains, there was no longer any danger in Hanxi Province, which caused him to be a little slack in reality.

Of course, the current Xia Kingdom is rapidly becoming stronger, the number of testers in various provinces is growing faster and faster, and the strength of the testers is also steadily improving. The Shifang Religion can be directly transmitted to the Daxia Dynasty. The martial arts under the Dynasty are basically controlled by the testers. Nowadays, most newcomers entering the deep realm can quickly get the protection of the Xia Kingdom, which is much better than the Yang Dai period. .

  Sha Sha Sha Sha and travel through reincarnation got the treatment of Yang Dai at the beginning. Skynet is full of all kinds of information about them. They are both SS-level talents, and the people are expecting them to become the next overlord, but Jiang.

As for Yang Dai, the people have already regarded him as the strongest, and people have become accustomed to him, so his reports are a lot less, and most people are beginning to look forward to the rise of newcomers. Yang Dai is like the way of heaven before, although there are few Report, but no one will forget him.

   The most famous thing about the Xia Kingdom recently is the appearance of a secret realm in the Longjiang River running through the Xia Kingdom. It is not the first time that a secret realm has appeared on the earth. Just like in the deep domain, there may be races from other worlds in the secret realm, and opportunities and dangers coexist.

  No aliens have been found in the secret territory of Longjiang for the time being. The testers have found a lot of treasures and crafting materials.

  Yang Dai also felt that the national luck was coming, but he didn't know when he would be able to have a wave of blessings.

   Six hours later, Yang Dai took back the yin crowd and re-entered the deep domain.

   It was not yet dawn, and the Guiyuan Shenglou, located in the mountains and fields, was like an ancient relic standing still, exuding an ancient and mysterious atmosphere.

  Boom!

   Guiyuan Shenglou rose from the ground, jumped over the mountains, and flew to the horizon.

  Yang Dai began to follow the direction indicated by Chu Ling's letter, and the white-browed Taoist happened to know the place pointed out in the letter.

"Xianhuiling is a famous forbidden place in the wild. Legend has it that immortals once fell here. For thousands of years, many immortals have gone to find opportunities one after another, but they have found nothing. There will be scenes of immortals fighting, which will make immortals fascinated, so even if there is no chance, it is still very famous."

  The white-browed Taoist said, and the Yin people were curious about it.

   Yang Dai asked, "Is it dangerous?"

   Baimei Dao Ke said: "Since it is a forbidden area, it is naturally dangerous, but with our current strength, we have nothing to fear. I once roamed Xianzhuiling alone, and I can come and go freely when I cultivate in the Soul Refinement Realm."

   Yang Dai breathed a sigh of relief upon hearing this.

Speaking of the forbidden area, he couldn't help but think of the Guikuling Mountain that descended when he first entered the deep domain. It was really a nightmare. He suspected that he was the only newcomer who came to the Guikuiling Mountain at that time. If there was no Shilong, he would have died too.

  Yin people began to discuss the various Jedi in the wild land, and Yang Dai was also listening. It is always right to know more.

   Half a day later.

   Guiyuan Shenglou was still flying, and Yang Dai was exchanging swordsmanship with Murong Changan.

  [The Nether Trial 'Jiuyou' kills the Earth Human Trial 'Sadness Reverse Current']

   Yang Dai's pupils shrank when he saw this line of prompts.

   finally started!

   Friction between the tester and the nether tribe.

  There is a notice from the deep domain, and the two clans will inevitably fight, because hatred is in front of us. At first, there are a small number of people, and the hatred will roll more and more until a **** battle breaks out.

   In addition, according to what Tian Jue said, the Nether Race is a murderous race, so the rhythm of the war will come quickly.

  Yang Dai intends to pass the test of Tianfu first and clean up the Nether tribe.

The stronger the    Nether Race, the more he wants it.

  Although he has mastered 4.6 million yin people, he will not be satisfied, he will only want more.

  The next target is thousands of Yin people!

  Yang Dai was a little excited just thinking about it.

   Unlock milestone missions!

  咻!

   Murong Changan stabbed with a sword. This sword was extremely tricky, but even if Yang Dai was distracted, he could see the move.

   The two swords collided, the sword light shone, and the movement speed of the two was very fast.

   Murong Changan said with emotion: "Master, it's a pity that you are not talented enough to be a sword cultivator."

  Yang Dai usually practiced too many spells, he hoped that Yang Dai could specialize in kendo.

  Yang Dai smiled and said, "It's still far worse than you."

   Although he is still in the Soul Refinement Realm, his body, spiritual power and soul are already comparable to the Void Stepping Realm. Even so, he feels that if he really fights Murong Changan to the death, he may not be an opponent.

  Murong Changan is not only talented, but also has hundreds of years of experience, which is incomparable to Yang Dai.

   Murong Chang'an said, "It seems that Tiansu Zhenren is indeed a master of Taoism. You can see your talent at a glance, and then pass it on to Senior Sister Ni."

   Yang Dai asked, "How much do you know about Tiansu Zhenren?"

   "Very few. It is rumored that this person is a land immortal, and his Taoism is unfathomable. Because he has a heart to save the world, he rarely participates in battles, so no one knows how strong he is."

   Murong Changan said with emotion, there is such a person in this world, who walks the world for the common people, even the demons admire him.

  The vast majority of immortal practitioners are selfish. They cultivate for longevity, strength, fame and fortune. There are very few people who can cherish the world.

  Yang Dai had a bold idea in his heart.

  Tiansu real person is not a god!

  Otherwise, how could this fellow wantonly give the testers a chance, the pattern is too big.

   Forget it, it’s just a guess anyway.

  Yang Dai no longer thinks too much, and concentrates on learning from each other.

  …

   Three days later.

   Guiyuan Shenglou finally came to the vicinity of Xianzhuiling. Yang Dai and others walked out of the building door, stood on the corridor, and looked at Xianzuiling in front.

  As the sun sets in the west, Xianzhui Ridge is rolling and rolling, the mountains are so dark, like a moat on the horizon, here is the end of the world.

   Guiyuan Shenglou did not stop, and flew directly into Xianzhui Mountain.

  Yang Dai clearly felt that the aura became thinner, and there was a disturbing aura in the air.

   "It doesn't look like a place where there are people. Could it be that there is a teleportation formation in Tianfu?" Wan Tianhao said, the Eagle Eye of God has been activated, and he is looking into the distance.

   Baimei Dao Ke said: "I don't know, I didn't find the teleportation circle when I came here before, and I haven't heard of it over the years."

  Yang Dai said: "The letter said to go to Xianzhuiling and find a mountain wall engraved with the Diamond Sutra. Xianzhuiling is so big, it seems that the yin will be activated."

   Baimei Dao Ke said: "I have never encountered such a mountain wall, and I have never even heard of the Diamond Sutra. It is true that I can only rely on a large number of Yin people."

The doors and windows on the seventh floor of the Guiyuan Holy Tower were all opened, and a large number of yin people flew out. Yang Dai summoned millions of yin people in one breath and made them rush in different directions. Practice literacy.

   The flight speed of Guiyuan Shenglou began to slow down, and Yang Dai stood outside the door, enjoying the scenery of Xianzhuiling.

  The vast atmosphere and endless mountains are rare on earth.

  【Earth human race tester 'kill kill kill' kills ghost race tester 'Cheng Chu'】

  【Earth Human Trial 'Kill Sha Sha Sha' kills Nether Trial 'Yu Beifeng']

  Two reminders sounded in front of Yang Dai, causing him to raise his eyebrows.

  Sha Sha Sha Sha has not yet entered the Spiritual Light Realm, yet he actually killed two Nether Trials one after another.

   is very good!

  The next generation is terrifying!

   Yang Dai said with emotion, this is good, the more powerful characters appear in the Xia Kingdom, the more confident the race will be eliminated in the future. If you can only rely on Yang Dai forever, how far can you go?

  The yin people don't know what Yang Dai is thinking, they are discussing what kind of assessment will be made by Tianfu.

   An hour later.

   Finally, a yin congregation passed the news to Yang Dai: "Master, I have found the Diamond Sutra, am I waiting in place?"

   "Well, wait for us to arrive."

  Yang Dai immediately recalled the other yin sect, and then controlled the Guiyuan Shenglou to fly towards the yin sect.

   He can feel the breath of every yin, and the yin can also feel his breath, which can save a lot of time.

   During the journey of Guiyuan Shenglou, there are constant return of the yin people.

   Half an hour later, Guiyuan Shenglou came to the vicinity of the yin clan, and half of the yin clan did not return at this moment.

  Boom!

Guiyuan Shenglou fell to the ground, Yang Dai summoned Xingsheng, surrounded by powerful Yin people such as Xingsheng, Sun God, Jiantu, Murong Changan, etc., Baimei Dao Ke and other weak core Yin people stayed behind Guiyuan Sheng building.

   This is a wild country ridge with a wide field of vision. The mountains are not dense, there are few weeds all over the mountains, and most of them are all kinds of fine rocks.

  Yang Dai and others came to a mountain wall, and the demon cultivator guarding here immediately saluted Yang Dai.

  Yang Dai looked at the mountain wall. The mountain wall was five zhang high and two zhang wide, like a plane cut by a knife. The stone surface was as smooth as jade. It was engraved with dense characters. The largest three characters were the Diamond Sutra.

   "It's really the Diamond Sutra."

  Yang Dai muttered, he was worried that the yin people didn't know what the Diamond Sutra was before, but it seemed that he was overthinking it, and the Tianfu assessment was not so frustrating.

  The yin people all looked at the mountain wall.

  Sage Punishment opened his mouth and said, "This Diamond Sutra is the Dharma of ancient Buddhism. You can memorize it, and you may be able to use it in the future."

   When he said this, everyone began to memorize it seriously, including Yang Dai.

  As a soul-refining realm, Yang Dai has been able to remember it in his memory, and he will remember it in his heart after reading it once.

  The full text of the Diamond Sutra is seven hundred and thirty-two words. After reading the entire text, there is nothing special about it. It can be recited repeatedly, and the mood is inexplicably cheerful.

   "Yes, yes, you can upload it to the secret network to benefit the people of Xia. Now people are too impetuous."

  Yang Dai thought silently, alas, he really thinks about others too much, am I a Virgin?

  The sun **** frowned and said: "And then? Just waiting here? Can't see the people in Tianfu!"

   The other yin people also frowned and looked up. All directions were desolate. Except for them, people were rare, and they couldn't even see the trace of monsters. How could there be any assessment?

   Saint Xing stared at the stone wall and said, "It should be inside, this is a test in itself."

   He stepped forward and squatted in front of the stone wall. He was almost as big as he squatted down when he was 100 meters high, and he immediately blocked everyone's sight, but no one dared to speak up. After all, they were big bosses.

  Yang Dai said with emotion: "There is an old man in the family, if there is a treasure."

   He was the one who dared to make fun of him, and the other yin people didn't dare to answer the question. After all, Liu Junjie was left in the Guiyuan Shenglou.

   After a while, Xing Sheng got up and everyone looked at him.

   Xing Sheng said: "Tianfu, maybe I know that their predecessors are indeed holy places, but I didn't expect that they will still stand for ten thousand years."

  The Sun God urged: "What is the assessment?"

   Xing Sheng turned around, looked at Yang Dai sideways, and said, "Master, the Diamond Sutra contains a powerful soul, which may be the fairy shadow mentioned by the white-browed Taoist. If you defeat him, the wall will dissipate, which should be the assessment."

   Powerful soul?

   Yang Dai frowned and asked, "How strong?"

   Xing Shengdao: "Beyond the Void Stepping Realm, you should have already entered the Tianyuan Three Realms. I don't know how strong it is for the time being, but since it is an assessment, you must not be sent to death. I guess it is the Tianyuan first realm."

  Tianyuan Three Realms?

  Xionglie couldn't help but ask, "What exactly is the Tianyuan Three Realms?"

  Sage Punishment replied: "The three realms of Tianyuan are divided into silence, yin and yang, and heaven and earth. Those who enter silence can obtain thousands of years of life, and can divide their souls, leaving a ray of vitality."

  Into silence, yin and yang, heaven and earth…

  Yang Dai silently wrote down that the known realm was finally refreshed.

  Gathering Qi, Heart Spinning, Spiritual Lighting, Empty, Soul Refining, Stepping on Void, Tianyuan Entering Silent Realm, Tianyuan Yin-Yang Realm, Tianyuan Qiankun Realm!

  Yang Dai asked, "How many yin people do you think will be needed to take it down?"

   Powerful soul?

   That is, it can be absorbed!

   Yang Dai's ambition was suddenly stimulated.

   The Sage of Punishment pondered: "It should be enough for two million Yin people to cast a great formation of ten directions."

   Yang Dai heard this and said, "Then three million Yin people!"

The   Ten Directions Battle Formation does not restrict races. Yang Dai has spread to all races, and even spirits can participate. Spirits do not need too complicated station changes, just provide demon power.

  Yang Dai immediately summoned the Guiyuan Shenglou, put all the yin inside into the soul space, and then put the Guiyuan Shenglou into the Guiyuan Qiankun bag.

   "How to get in?"

   Yang Dai asked, he couldn't wait.

  Sage Punishment said, "Any time."

  Yang Dai said: "Then..."

"and many more!"

   A voice suddenly came, and everyone turned their heads to look, only to see a woman in a purple dress flying over, as if a flying fairy from the sky descended to the mortal world.

  Chu Ling!

   I have to say that Chu Ling's appearance and image temperament are really outstanding, and she is the most outstanding woman Yang Dai has ever seen.

   But when Yang Dai saw her, he couldn't help but be afraid.

   This woman is not easy to judge!

   "You don't have to do it."

  Yang Dai said, stopping some yin people who wanted to do something.

   Chu Ling landed, not close to Yang Dai, the two sides were ten steps away, which was a very dangerous distance.

  Chu Ling looked at Yang Dai, tsk tsk admiringly said: "Your growth rate is really amazing, as expected of a good seedling I like, the assessment inside is too threatening, you don't have to worry."

  Yang Dai said: "If you're not in a hurry, wouldn't you have to wait?"

  Chu Ling threw a wink at him, covered his mouth and smiled: "If you please me, I can directly let you join Tianfu."

  Yang Dai was unmoved and said, "What is your intention? Why did you plan the magic way to attack us aliens?"

Chu Ling shrugged and said, "It wasn't me who planned it, but there was absolutely no God's envoy. I just pushed the fire and investigated the secrets behind Jianzong and Jue Wutian. Think about it carefully. Although I appeared in the battle of the Ten Directions Religion, but I But I didn’t take it seriously, and my attitude was already obvious.”

   Jiantu hummed: "I think you are afraid of death?"

  Chu Ling smiled and said, "Senior Jiantu, you can't do it, can't you see my realm?"

  Senior, she deliberately emphasized the accent, and the meaning of ridicule was very obvious.

   Xing Sheng said: "She is in the Tianyuan realm, so she can easily grasp my soul, and even use it for herself."

  Tianyuan Realm!

   Everyone was shocked, Yang Dai frowned.

  Chu Ling smiled and said: "Don't be nervous, I really value you. To be precise, I am very optimistic about your aliens. I want to select more aliens for Tianfu and use your talents to deal with the talents of aliens."

   Interracial?

   Yang Dai asked, "What is an alien race?"

Chu Ling said: "The races that descended from the sky are not only your aliens, but also other races. You should have come into contact with them. Tianfu is currently facing many threats from aliens, and the talents of aliens are too powerful. To deal with aliens, of course, Tianfu will also try to train you aliens, and the two sides will support each other."

  Yang Dai was silent.

  Chu Ling asked curiously, "What level of talent are you?"

   Yang Dai asked in surprise: "You even know this?"

"Of course, Tianfu has a history of dealing with alien races for hundreds of years, and I have already learned some information, such as talent levels. At present, the levels I know are heaven and earth level and cosmic level. Tiandi level is the definition of levels in different small worlds, while cosmic level It is beyond the limit of one's cognition of heaven and earth. When you reach this level, you will get a sense of heaven. At present, Tianfu is facing the talent of cosmic level, which is very troublesome."

   Chu Ling's words made Yang Dai stunned.

   Tiandao induction?

   He didn't.

   In this way, E-level to SSS-level are the category of heaven and earth, which is the definition of the level within the earth.

   That’s right, if the SSS level is the top, how can the Earth Humans be ranked beyond 100,000?

  Yang Dai suddenly felt the pressure, and there was no cosmic talent on Earth.

   Fortunately, with Ji Yunyan there, in a few months, Ji Yunyan will be able to break through to the void, and then he will be able to upgrade his talents.

  Chu Ling saw through his thoughts and said with a smile: "Don't be nervous, you have a very high talent limit, and you will definitely grow to the cosmos level in the future. I trust my judgment, let's go, and follow me directly to Tianfu."

  Yang Dai took a deep breath and said, "Recently, the wild land has come to the Nether Clan, do you know anything about the Nether Clan?"

Chu Ling said: "Of course, this ugly race has been in contact with Tianfu for a long time. Not long ago, there was no heaven to lead them to the wild land, and the crime was extremely evil, but these Nether races are not very strong, and they are handed over to you aliens. We understand that these extraterrestrial races seem to be involved in a trial of heaven, and it will be good for you to kill the Nether Race."

  Yang Dai was even more curious about Tianfu, but he did not expect Tianfu to know so much about the Deep Domain.

  Joining Tianfu is of great significance to Xia Kingdom, so I must be the first person!

  Yang Dai thought silently, and then said, "Okay, but I still want to try it. I took the soul inside, do you have any opinion?"

  Chu Ling was stunned for a while, and said, "The soul inside is very strong, stronger than the remnant soul of the great saint next to you."

  Yang Dai smiled and said, "I have more than one yin."

  Chu Ling was silent.

   She backed away silently, making a gesture of your request.

  Yang Dai gave Xing Sheng a look, Xing Sheng immediately raised his hand, and the spiritual power spurted out from his palm, hitting the stone wall head-on.

  …

  In the boundless wasteland, a large river with a width of 100 feet divides the earth in two. The waves are fierce, and sharp rocks emerge from the riverside at the bottom of the cliff, which are sharply beaten by the river waves over time.

   On the cliff, two figures stood side by side, one of them was Emperor Meng.

   Today's Emperor Meng has lost his youthful appearance, his face is resolute, his eyes are no longer as sharp as before, and his whole person is calm and unfathomable.

   Standing next to him was a young man. The young man's hair was as long as his shoulders, blood red, and he looked extremely coquettish. His face was not handsome, but there was a fierceness in his eyebrows.

   "Four kills, the front is the place where the Nether clan gathers, do we really want to go?" Emperor Meng asked.

   Four kills are kill kill kill kill.

  Shashashasha had an indifferent face, and said, "The war between the Nether Race and us is inevitable. It just so happens that you and I both need to fight to become stronger. Why should you be afraid? At present, the Nether Race is just like that, it's not that strong."

   Great Emperor Meng frowned and said: "Don't be careless, I can feel a lot of tyrannical aura, at least it's an empty cultivation base."

  Sha Sha Sha Sha said: "Since this is the case, then we will wait and hunt for the lonely Nether tribe."

"Um."

  The two looked at the end of the earth opposite the river.

   Hundreds of miles away, there are densely populated humanoids in the wasteland, which are the Nether tribe.

   Nether people are human-like, with dark purple skin. Some are as huge as mountains, and some are as short as dwarfs. They wear highly technological battle clothes, most of which are dark.

   Looking around, there are millions of Nether people.

A camp has been set up at the very center. A burly man who is 20 feet tall is holding a scroll. His facial features are straight, but it is in line with the aesthetics of human beings. His eyes are like snakes, and his skin is dark purple. There are red lines that look like blood vessels on the top, two horns on the head, and it looks like a demon. Behind him stands an extremely exaggerated big knife, the blade is half a zhang wide, and the cold light is piercing.

   His name is Zhenkui Shengjun, and he is the leader of this Nether tribe army.

   A female ghostly person came over and said, "Holy Monarch, the earth human race is hunting my race, do you need to deal with it?"

  The Holy Monarch Zhenkui stared at the scroll in his hand and said: "Just send any troops, choose the generals who step into the virtual realm to lead, enough to deal with the earth human race, this clan is weak and will be our prey sooner or later."

The    female nether nodded, her eyes fell on the scroll in his hand, and she asked, "Holy Monarch, what are you looking at?"

Zhenkui Shengjun said: "I am browsing the deeds of the swordsman, and there is no one who has ever said that the swordsman has good fortune. The purpose of the nether clan this time is to find the swordsman. The racial elimination is coming, and our enemy is very strong. We need more power."

The    female nether frowned, thinking of the elimination of the race, and her eyes showed anxiety.

   Immediately, she stopped disturbing and silently stepped back.

   Holy King Zhenkui frowned and murmured: "Strange, the growth of this swordsman is too unreasonable, does he also have talent?"

  …

  In the mysterious space, the cosmic starry sky hangs high above the earth, and the earth is barren. Yang Dai is madly summoning the yin, and the black mist fills tens of thousands of meters and spreads rapidly.

  Yang Dai's eyes were fixed on the front, only a hundred feet away, a huge purple crystal was suspended in the air, and a terrifying figure was curled up in the crystal, and it was difficult to see its true face.

   "Array!"

   Murong Chang'an shouted loudly, the yin crowd quickly surrounded the purple crystal, and they moved quickly and without any hesitation.

  Crack!

  The purple crystal produced a crack, which moved Yang Dai.

"hurry up!"

   he urged in his heart.

   Soon, the purple crystals were surrounded by millions of yin clans, and the endless yin clan continued to form an encirclement circle, circle after circle, and the number of people in the formation grew rapidly.

   The Punisher was suspended in the air with his evil spirit, ready to attack at any time.

  The cracks on the surface of the purple crystal became more and more, Yang Dai became more and more nervous, and he already felt a terrible aura.

   Beyond the Void Realm!

   "Form formation!"

   Murong Changan shouted loudly, millions of demon cultivators formed a formation, their spiritual power exploded, the formation shot up into the sky, and the air column shot straight into the starry sky, isolating the purple crystal from the sword formation.

  Yang Dai breathed a sigh of relief and finally formed a formation.

There are 15 Void Stepping Realm, 125 Soul Refining Realm, etc. in the Ten Directions Boundary Formation. The formation is formed, the formation is continuously strengthened, and the air column is rapidly thickening.

1500000!

  Two million!

   The number of Yin people entering the battle is still growing, and the anxiety in Yang Dai's heart has completely dissipated.

   Steady!

  ping—

The    purple crystal was completely shattered, and the soul inside was revealed. This was a man with white hair covering most of his body. He was wearing a white robe, his skin was pale, and there was no blood at all, making him extremely frightening.

   He raised his eyes, the pupils turned out to be gray, at first glance, it seemed that there were no pupils, he stared at Yang Dai and others indifferently.

  The yin people looked at him, all feeling a chill in their hearts.

   "Town!"

   Murong Changan shouted immediately, his voice resounding under the sea of ​​stars.

  Rumble—

   A rolling thundercloud quickly condensed above the ten-direction slamming formation, and endless thunder and lightning were interweaving, ready to go.

   The man in the white robe stood up straight, with his arms outstretched, as if stretching his muscles and bones.

   At this time, a thunder and lightning struck down!

  He raised his head suddenly, opened a vertical eye between his eyebrows, and a white light shot out from his eye, which directly dispelled the lightning.

  The hearts of the yin people are beating wildly, and they fully support the great formation of the Ten Directions.

  Boom! boom! boom…

   One after another thunder and lightning fell frantically, and the man in white robe raised his hand, facing Leiyun with his palm, condensing a white mask, which easily resisted the bombardment of the thunder in the sky.

"wind!"

   Murong Changan shouted again, a terrifying gust of wind erupted in the air column of the ten-sided formation, crushing the white-robed man in the center of the formation.

   The shield around the man in the white robe was directly twisted, and he frowned.

   Sheng Xing stood outside the formation, staring at the white-robed man from a distance, and muttered: "This breath...a bit familiar..."

   at this time.

  Yang Dai continued to summon the Yin crowd.

  Three million may not be enough, he is ready to overwhelm the underworld with four million.

   Must crush this guy!

"fire!"

   Murong Changan shouted angrily, the ground inside the formation suddenly cracked open, and the rolling fire surged out, growing rapidly, turning into a surging sea of ​​flames that drowned the man in white robes.

   The white-robed man's brows furrowed even tighter. He slapped it with a palm, and the space under him instantly condensed into ice. A very thick layer of ice blocked the sea of ​​fire, but the ice layer melted very quickly.

  Can't stop!

   Tomorrow will resume 10,000 shifts. There is a strong wind in Chongqing today. My computer desk is next to the floor-to-ceiling window.
