Immortal Mansion Longevity

   One day later.

  Yuan Kingdom, Yuanyangzong.

  Tongtian Peak Cave Mansion.

  In the practice room, Liu Yu sat cross-legged, summing up the gains and losses of the trip.

  The reason for this line is mainly to obtain the fourth-grade spiritual fire and improve the rank of the Qingyang magic fire.

  Since the goal has been achieved, even if there is no additional gain, it can be considered a complete success.

   However, killing a Nascent Soul True Monarch in order to get the Spirit Fire, naturally it is impossible to have only one harvest.

  In addition to the Jiuyou Demon Fire, Liu Yu also obtained two real treasures, as well as all the net worth of the Bone Old Demon.

  Before leaving the Black Bone Sect, he searched the treasure house of his sect along the way.

  Although there were no unexpected surprises, he still obtained a large number of spiritual stones, magic weapons, talismans, and spiritual herbs.

  Spiritual stone artifacts have little effect on Liu Yu today.

  However, the Black Bone Sect's hundreds of years of treasures are still greatly enriched, and his reserves of spiritual herbs and medicines.

   "Among the spiritual herbs harvested this time, there are even a few important auxiliary medicines for refining "Zhen Zhen Dan"."

   "Counting these few plants of auxiliary medicines and refining the spirit grass and elixir of "Zhenzhen Pill", it will be seventy-seven eighty-eight."

   "The main medicine "Tianxincao" was found by the dead, and most of the auxiliary medicines were collected through the sect. The rest should not be collected in many years."

   "You only need to sharpen your mana, and when you have collected all the spiritual herbs and refined the elixir, you can start to break through the middle stage of the Nascent Soul."

  Liu Yu stroked the storage ring, thoughts flashed in his mind, and he was in a good mood thinking about it.

  In the past fifty years, of course he has not lost the way of alchemy.

  Through the practice of ripening a lot of spiritual herbs in the Immortal Mansion, and discussing with Mo Mei about alchemy experience from time to time, the success rate of his refining "Feixian Pill" has reached an astonishing 40-50%.

  Although he has not yet refined other fourth-order elixirs, it is not a problem for Liu Yu's alchemy attainments to firmly establish himself in the realm of a master.

   Once the "Zhenzhen Pill" spirit herbs are collected, you can start refining them immediately.

  The way of cultivating immortals becomes more and more difficult. Even though he has extraordinary aptitude for using the secret method to conceive a baby, he still inevitably encounters a bottleneck.

   Without breaking through the bottleneck, the cultivation base cannot continue to improve.

  If it takes time and painstakingly polishing tens of hundreds of years of cultivation, Liu Yu is sure to break through.

  But the leak of Lingbao's news is like a sharp sword hanging above his head, which does not allow him to practice slowly step by step.

  We must improve our strength as soon as possible.

  Although the news of the Ruined Sword may not be leaked, Liu Yu has no habit of entrusting his own safety to an illusory fate!

  So as early as when the four kinds of pills were in hand, he began to collect the four kinds of elixir at the same time, the necessary spiritual grass and elixir.

   After all, mastering a Nascent Soul sect, and a group of loyal dead soldiers under him, has gained a lot in the past few decades.

   "Unfortunately, in order not to reveal my identity, I can only give up the Black Bone Sect's spiritual veins."

   "Otherwise, if it is integrated into a fourth-rank low-grade spiritual vein, the rank of Tongtian Peak's spiritual veins will definitely be improved a lot again, and it will be one step closer to the fourth-rank high-grade."

  Thinking about the Black Bone Sect Youyue Mountain Spirit Vein, Liu Yu slightly shook his head with regret.

   Migration of spiritual veins is not a matter of a day or two, and the movement is so loud that it is impossible to hide it.

  Weighing the pros and cons, he can only give it up, not knowing which boss will be cheaper.

   "It's still not enough greed."

   Immediately, Liu Yu laughed at himself, scolding himself for being too greedy.

   After getting Jiuyou Mohuo and all of Bone Old Demon's net worth, and accidentally harvesting several important auxiliary medicines for refining "True Pill", he is still not satisfied.

  Smiling slightly, Liu Yu turned his gaze to the things placed in front of him.

   are a bone knife refined from unknown bones, a white orb the size of a goose egg, and a pitch black ring.

  It is the real treasure of the bone knife, white orb and storage ring of Old Demon Bone.

   "With space attributes, this bone knife is quite extraordinary."

   "Not only is the attack powerful, but it can also play a role of surprise at some critical moments."

  Picking up the real treasure of the bone knife, Liu Yu examined it carefully.

  The flying speed of the magic weapon is extremely fast, far surpassing the escape speed of a monk, but no matter how fast it is, it cannot be faster than space travel.

  Bone Knife True Treasure has a space attribute, which can be moved in space and appear at any position within a certain range.

  At critical moments, it can be used as a surprise move.

   "It is indeed a good magic weapon for murder and arson."

   "In order to refine this treasure, the bone old devil must have spent a lot of effort."

   "But now it belongs to Liu."

   Gently stroking the bone blade, feeling the uneven texture, Liu Yu found a line of small characters on the handle.

   "Bone Crack Empty Knife"

   Not surprisingly, this is the name of this knife.

  Liu Yu is a good follower, and has no idea of ​​renaming it, so he will call it this way in the future.

   "This knife is rare."

   "Although I already have the Sunset Golden Spear in terms of attack, I can still use it."

   After looking at it for a while, he put the "Bone Cracking Empty Knife" aside, intending to keep it for his own use.

   Immediately, Liu Yu picked up the white orb again, and also found three small characters on it—Yin Mingzhu.

   Logically speaking, true defense treasures should be more rare than attack true treasures.

   But in terms of defense, he already has the "Red Flame Shield", which fits well with his own attributes.

  In terms of quality, the Yinming Orb does not exceed the Scarlet Flame Shield. Since it is a true treasure of the Yin attribute, Liu Yu can only exert about 70% of its power after sacrifice.

   It has no rare characteristics, and its quality is not as good as the Red Flame Shield, and it is also at odds with his attributes.

  In this case, the Yinming Pearl is a bit tasteless.

  Liu Yu thought about it, but gave up the idea of ​​sacrifice, and planned to save it for future exchange with other true monarchs.

  After all, in terms of defense, he already has a lot of means, no matter "Youxia Armor" or "Red Flame Shield", the defense power is very good.

   And if the body training has reached the fourth level, it is not a problem to resist some fourth-level spells.

  After thinking about the uses of the two real treasures, Liu Yu began to sacrifice the pitch-black storage ring. Since the bone old devil had died, the sacrifice went very smoothly.

  Effortlessly erase the brand of divine consciousness, get rid of the mana breath in it, and then put on your own brand.

   With a thought in mind, Liu Yu probed his consciousness into the dark storage ring with some anticipation.

   But this look, it is a big disappointment.

  In the Bone Old Demon storage ring, apart from a large number of spirit stones, the most common ones are materials for refining corpses and ghosts.

   For example, corpses, living souls, etc.

  The corpses and living souls were all processed and placed neatly, but there were not many spiritual herbs and spiritual materials.

   "Such a net worth, not to mention compared with myself, even compared to ordinary early stage true kings."

  After reading it, Liu Yu was a little disappointed.

  He didn't intend to study the way of the corpse anymore. With the rapid growth of strength, even the "Thousand Soul Banner" has been useless for a long time.

  So the large number of corpses and living souls in the storage ring are tasteless to him, and it is a pity to discard them.

   "Leave it to Qiu Shui."

   Thoughts turned, Liu Yu quickly figured out how to deal with these corpses and souls.

  He can probably guess why the Bone Old Demon is so poor.

  In order to break through to the mid-term stage, a lot of resources are required to be consumed. In addition, to increase the combat power of the bone snake to refine corpses, I am afraid that most of this person's net worth has been wiped out.

   In this way, there are naturally not many good things left.

   After counting the loot, Liu Yu was not in a hurry to refine the "Bone Cracking Empty Knife", but put away the three items one by one.

  Then, the storage ring had a flash of inspiration, and a jade box made of thousand-year-old black ice instantly appeared in front of him.

   "click"

  Tear off the spirit sealing talisman, and with a soft sound, the jade box opens.

  A faint blue flame remained motionless in the jade box, and only jumped slightly after a long time, in the state of being sealed.

   It is the Nine Nether Demon Fire!

   "With sect disciples and dead soldiers under him, it is not a problem to collect the flesh and blood of monsters."

   "Once the Qingyang Demon Fire is promoted to the fourth rank, it will be able to obtain a large amount of fuel to increase its power."

   "At that time, the power will be extremely impressive, so the promotion is as fast as possible."

  All kinds of thoughts flickered, Liu Yu shot out a mana, controlling the blue flame to float in front of him.

   Without the suppression of the spirit-sealing talisman, as soon as it left the Xuanbing jade box, the beating speed of the Jiuyou Demon Fire accelerated, emitting high temperature and slowly recovering.

   "Zi Zi ~"

   It can be clearly felt that it is becoming active.

   There is no need to delay, everything is ready, Liu Yu immediately started the promotion of the magic fire.

  His hands pinched the formulas firmly, and immediately he played dozens of formulas, falling into the blue flames one after another.

   "Boom!!"

  In an instant, an extremely powerful force naturally emanated from the dark blue flame the size of an adult's head.

  This level of power is obviously more than many real treasures, easily reaching the fourth level, comparable to some real kings.

  As if being stimulated by some kind of stimulation, the flames of the Nine Nether Demons became brighter and beat more frequently.

  In the space, the fire-attribute aura pervading everywhere also began to become active.

  As the creator of the secret technique, Liu Yu is naturally very familiar with the "Nine Transformations of Magic Fire".

   Immediately, carry out the first step in an orderly manner, and play a series of formulas without haste.

  As one after another method was played out, the stimulation of Jiuyou Demon Fire became stronger and stronger, and its power slowly climbed upwards, reaching the level that low-level monks would be daunted by.

   At the same time, wisps of extremely pure milky white spiritual power also overflowed from the flames the size of an adult's head.

   These strands of spiritual power seem small, but in fact the "quality" is very high.

  It is similar to the mana of the Nascent Soul Stage, but it is different from the mana of the Qi Refining Stage.

  The total amount of aura contained in a ray of mana in the former may far exceed the sum of all the mana in the latter.

   Losing the restraint and control of the spiritual fire, the hair-like milky white spiritual power directly changed from order to disorder.

  As soon as it appears, it transforms from high quality to low quality.

   "Boom"

  In a short period of time, a spiritual storm appeared in the practice room, sweeping through every corner.

   Soon, atomization will appear naturally.

  The hair-like milky white spiritual power turned into a massive amount of heaven and earth spiritual energy, making the spiritual energy storm intensify.

   Seeing this, Liu Yu took out the Dongfu Token and immediately activated the Spirit Gathering Formation.

   "Buzz~"

  On the ground, array patterns lit up rapidly, absorbing the mist of spiritual energy in the space.

   This prevents the aura storm from expanding further.

  But because the Nine Nether Demon Fire is still releasing spiritual power, the spiritual energy storm has no intention of dissipating in a short time.

   In order to force out the source of the spiritual fire, it is natural to release most of its spiritual power to weaken its power to a minimum.

  Has performed the "Nine Changes of Magic Fire" secret technique three times, Liu Yu is very familiar with the whole process, so he is not surprised to see this scene.

   From time to time, he would cast out a formula, watching the power of the Nine Nether Demon Fire rise, and continuously release a large amount of spiritual energy.

  Fourth to sixth-grade spirit fires correspond to the early stage of the Nascent Soul to the late stage of the Nascent Soul.

  However, due to the special nature of the spirit fire, even the fourth-grade spirit fire may pose a threat to the big monk.

  The degree of rarity far exceeds that of ordinary real treasures.

  This kind of high-level spiritual fire, the aura contained in it can already be described as massive.

   Released in such a "gentle" way, it can't end in a day or two.

  Under the effect of the "Nine Transformations of the Demonic Fire", wisps of milky white spiritual power continuously overflow from the Nine Nether Demonic Fire, turning into massive amounts of low-quality spiritual energy.

  The aura is naturally atomized, forming a large-scale aura storm, but under the action of the spirit gathering array, it can never continue to expand.

  Time passed by every minute and every second, and after about seven days and seven nights, the power of the Nine Nether Demon Fire reached its peak.

   Immediately, it began to decline slowly.

  After seven days passed, the milky white spiritual power that overflowed from it gradually became rarer, and the scale of the spiritual energy storm gradually decreased.

   Until half a month later, the power of the Nine Nether Demon Fire declined to the extreme, and it took a long time for a ray of high-quality milky white spiritual power to float out.

"about there."

  Liu Yu flashed this thought, and immediately flipped his left palm.

   "噗~"

  The next moment, a dark green flame emerged from his palm.

  Dark cyan, light cyan, light red, pure white.

  In just an instant, the color of Qingyang Demon Fire changed one after another, representing all the characteristics it has now.

  Growing to the peak of the third rank, swallowing three spiritual fires successively, this fire already has three characteristics.

  respectively: Qinglian Linghuo's "vegetation affinity", Manduo blood flame's "burning flesh and blood", impermanent heart inflammation's "desire power".

  Control the Qingyang Demonic Fire, and slowly float to the vicinity of the Jiuyou Demonic Fire. The distance between the two spiritual fires is less than one foot.

   "disease"

   Seeing that the time had come, Liu Yu pinched the formula with both hands faster and faster, and even afterimages appeared.

  Hundreds of formulas were condensed into a three-inch red seal.

  As soon as he pointed out, the red magic seal fell into the blue flame in an instant, and its power was weakened to the extreme. The Jiuyou Demon Fire was powerless to resist.

   "Zizi"

  Although the blue flames surged violently, due to lack of spiritual power, the power did not increase at all.

   Instead, it entered with red seals, and its shape began to be a little unstable.

  Finally, after the ninth red seal fell, a very special blue aura floated out from the Nine Nether Demon Fire.

  The source of spiritual fire!

   This blue aura is extremely special, as soon as the fire attribute aura in the space appears, it spontaneously gathers towards it.

  If you continue to absorb aura, based on this aura, you may not be able to become another "Nine Nether Demon Fire" in time.

  But because of the lack of origin, the rank may only be one or two.

  Under Liu Yu's control, this faint blue aura slowly floated into the blue flame next to it.

   Immediately, he used the "Nine Transformations of Demon Fire" to assist Qingyang Demon Fire to absorb and digest this source.

   "Zizi"

  Absorbed a bit of faint blue aura, and the fist-sized deep green flame violently surged visible to the naked eye.

  The body appears a little unstable, and its essence begins to change.

  But under Liu Yu's control, naturally there will be no accidents.

  One breath, two breaths, three breaths.

   After about three hours, this bit of aura was perfectly absorbed.

  Qingyang Demon Fire, which had already reached the peak of the third rank, got the origin of the fourth rank spiritual fire, and began to advance towards the fourth rank.

  Visible to the naked eye, the aura that was originally dark blue began to be stained with a faint blue color.

   The first refinement was successful, and the next thing will happen naturally.

   Under the observation of Liu Yu's keen spiritual sense, it is impossible for any mistakes to occur.

  With insufficient spiritual power and the loss of part of the original Nine Nether Demon Fire, it is even more powerless to resist Liu Yu's manipulation.

   Can only be slaughtered and weakened step by step.

  …

  Seven days later.

   "Bang~!"

  Having lost most of its origin, the extremely weakened Jiuyou Demon Fire finally couldn't maintain its shape.

   It exploded with a bang, turning into dots of blue flames.

  Although the practice room was extremely rich in aura, the dots of blue flames could not stop being extinguished one after another in the next few breaths.

  In the end, this Nine Nether Demon Fire completely dissipated between heaven and earth.

  Perhaps due to the restriction of the rules of the Dao, it is impossible for two identical fourth-grade spiritual fires to appear in the world at the same time.

  Only when the old spiritual fire dissipates, can the new spiritual fire be born.

   Perhaps by chance, after tens, hundreds, or even thousands of years, a new Nine Nether Demon Fire will be born.

  It’s just a newly born spiritual fire, it’s not the one it used to be.

  However, in the practice room, the sound of burning flames did not disappear with the disappearance of the Jiuyou Demon Fire.

   "Zi Zi ~"

  Beside the Jiuyou Demon Fire before it dissipated, a dark blue flame the size of a fist was slowly beating and burning.

  The blue fire radiates in all directions, and this spiritual fire is as powerful as a rainbow, and it has truly reached the fourth-rank level.

  Compared to the Nine Nether Demon Fire in its heyday, its power is not too much, and there is still a lot of room for improvement when it is just promoted.

   It is the Qingyang Demon Fire that has reached the fourth rank!

   "Four products."

  Looking at the dark blue flame, a smile appeared on Liu Yu's face.

  Through the close connection in mind and mind, he is very sure at this time that Qingyang Demon Fire has reached the fourth-grade level.

   And because of the tailor-made "Nine Changes of Magic Fire", he can continue to be promoted in the future.

  Liu Yu beckoned lightly, and the Qingyang Demon Flame moved accordingly, returning to the palm of his hand to beat and burn.

  The spiritual sense spread out, and he could clearly feel that under the influence of the Qingyang Demon Fire at this time, the surrounding fire attribute aura became much more active.

   "Judging from the activity of the fire attribute aura, the Qingyang Demon Fire is slightly less influential than the Nine Nether Demon Fire in this regard."

   "However, there is not much difference."

   "Due to the accumulation of the first three transformations, the fourth transformation of the Nine Demon Fire Transformations will make a great improvement, and can more completely inherit the characteristics of the original Spirit Fire."

   "In terms of affecting the aura of the fire attribute, it should be able to have 90% of the effect of the Nine Nether Demon Fire, which is considered a great improvement."

   After observing for a while, Liu Yu came to a conclusion in his heart and nodded slightly in satisfaction.

   "This kind of feature that can increase the activity of the surrounding fire attribute aura will be called "flame boost" from now on."

   "Affinity with vegetation, burning flesh, power of desire, and flame enhancement."

"Not bad."

  Give the characteristic a simple name, and looking at the promoted Qingyang Demon Fire, Liu Yu's eyes are bright and he is in a good mood.

   As for the "flame boost" feature, why the color is not dark blue, this point is insignificant.

   After all, the Qingyang Demon Fire is not intended to be a complete replica of the Nine Nether Demon Fire, and has not inherited all its characteristics.

   Immediately, his mind moved.

  The next moment, the Qingyang magic fire became blurred for a while, and the color changed between dark blue, light blue, light red, pure white, and dark blue, and even five colors appeared at the same time.

   After being promoted, the Qingyang Demon Fire changed into various forms under Liu Yu's control, and after testing the many changes of the fourth rank.

   At this moment, there was a sudden movement from the storage ring.

"Um?"
