Unlimited Upgrade

Walking into the training room all the way, Li Dong took out the dark iron plate to open the Ju Yuan formation of the training room, and then sat down.

"System, upgrade the Nine Secret Sutra of Tuntian to the first level."

"Deduct 100,000 practice experience points!"

When the system prompt fell, an unpredictable message flooded Li Dong's mind.

At the same time, Li Dong's body also began to undergo a mysterious change.

A large amount of vitality was crazily gathered beside Li Dong, constantly pouring into Li Dong's body.

Soon, Li Dong's cultivation level began to change.

The day after tomorrow is first heavy, the day after tomorrow is double...the day after tomorrow is five times.

When Li Dong's cultivation level was upgraded to the acquired fifth level, the information in his mind stopped transmitting, and a system prompt sounded in Li Dong's ear.

"Didi! Found the Overlord Sword Technique, it takes 10,000 practice experience points to cultivate to the first level, do you practice?"

"Swordsmanship?"

"Is this the secret technique that the prince obtained from the Nine Secret Sutra of Swallowing Heaven?"

Li Dong thought to himself, but he decided to ignore Tyrant Sword Art for the time being.

First cultivate the Nine Secret Sutras of Swallowing Heaven, and start up the cultivation base before talking about the Secret Techniques.

"System, practice the Nine Secret Sutra of Swallowing Heaven to the second level."

"Host, it takes half a million practice experience points to upgrade the Nine Secret Sutra of Swallowing Heaven to the second level. Does it increase?"

"Boost!"

As Li Dong's voice fell, a more mysterious message flooded into his mind.

The vitality group that had gradually dissipated was instantly pulled to Li Dong's side by a huge suction force.

And condensed a super-large vitality cluster with the original vitality cluster as the core, gradually covering the entire training room.

Li Dong's cultivation base is steadily improving, and he is in the process of improving to a higher level.

"what!"

A heart-piercing pain came from the depths of Li Dong's soul.

Enduring the pain, Li Dong's body was nourished by his vitality.

Constantly being torn apart, coming back together, becoming more and more tough.

At the same time, a swallowing breath that dominated the world flashed across Li Dong's body, and then converged into Li Dong's body.

A quarter of an hour later, the super-large vitality group gradually dissipated, revealing the figure of Li Dong sitting in the middle.

"It seems we still can't be too rush!"

"This time I improved, I almost finished playing myself."

Looking down at the naked body, the dense white fine lines spread all over, Li Dong exhaled a sigh of breath, thinking a little bit afraid in his heart.

This time, he almost finished playing himself.

In the process of ascension, because the Nine Swallowing Secret Scriptures were too domineering, and Li Dong's accumulated knowledge in front of him was not enough for him to cultivate into the second level of the Nine Swallowing Secret Scriptures.

Therefore, Li Dong simply couldn't control the vitality that surged into his body, and nearly exploded and died.

Having said that, Li Dong succeeded in practicing the second level of the Nine Secret Sutra of Swallowing Heaven, and his cultivation level also broke through to the Nine Stages of Acquired Heaven.

It's just a bit regretful that Li Dong didn't realize the secret technique of attack that the Nine Secret Sutra of Swallowing Heaven could comprehend because his spirit was not strong enough.

According to Li Dong's speculation, the second layer of the Nine Swallowing Secret Scriptures brought him the secret attack technique.

It should be after Li Dong breaks through to the innate realm before he has a chance.

Thinking of this, Li Dong was not depressed either.

"Isn't it just a secret technique!"

"It just happens to be too greedy to chew, so this prince will desperately improve the Domineering Sword Art, and raise the Domineering Sword Art to a realm unmatched."

"At that time, one method will break ten thousand ways!"

Thinking of this, Li Dong decided to see how much practice experience it would take to upgrade the Domineering Sword Art to the known ninth level.

"System, how much practice experience does it take to upgrade the Overlord Sword Technique to the ninth level?"

"Host, it takes 7.5 million practice experience points to upgrade the Overlord Sword Art to the ninth level. Does it increase?"

"Promote."

Hearing this practice experience value, although Li Dong felt distressed, he still gave orders to the system without hesitation.

After all, he can no longer quickly break through the realm of cultivation with the system.

Then he can only find another way, starting from martial arts to achieve the goal of gaining stronger strength.

"Buzzing...buzzing..."

This time the promotion was very fast, before half a sound, a shocking sword intent passed from Li Dong's body.

Li Dong felt very happy when he felt the countless sword energy suddenly emerging from his body.

He felt that by relying solely on the Domineering Sword Technique, he now has the ability to cross the realm and slash the innate strength with the sword.

Once the Tyrant Sword Technique and the Nine Secret Sutras of Swallowing Sky were combined, Li Dong even had the confidence to compete with the Grand Master one or two.

Outside the practice courtyard.

Integrating with the environment and responsible for protecting Li Dong's royal guard, Hou Thirteen sensed the monstrous sword intent rising from the cultivation courtyard, and could not help but draw an extremely stunning color in his eyes.

"His Royal Highness the Thirteenth Prince actually has such a terrifying sword intent. It seems that when the ancient human race battlefield opens next time, we Xuanhuang Emperor will definitely shine and drink the blood of the foreign race!"

In the courtyard, Li Dong's sword intent covers everything around him.

At this time, capturing the emotional fluctuation that Hou Shisan had just produced, Li Dong's eyes instantly turned towards the direction of Hou Shisan.

The sword intent generated by the ninth level of the Domineering Sword Art through the system is extremely domineering, allowing Li Dong to perceive some changes in his surroundings even if his cultivation has not reached the realm of the master.

With Yuan Li running to his feet, Li Dong's figure flashed, and he took a few feet in one step, rushing towards the position of Hou Shisan.

Hou Shisan outside the courtyard didn't know that he had been exposed, and he was feeling deeply inside.

When passing through the courtyard, Li Dong chose a branch at random and came to the back of the hiding place of Hou Shisan.

"Speak! Who are you from?"

Because he was not sure whether it was the one who was protecting him, Li Dong just put the branch he just picked right in front of Hou Shisan's neck.

Feeling the sharp sword air coming from the neck, the emotional color on Hou Shisan's face disappeared without a trace.

"Damn! This breath is the same as the sword intent that came out of the courtyard just now. His Royal Highness the Thirteenth Prince will not be so enchanting!"

"You know, the thirteenth prince, but the Emperor Pavilion who went to today chooses to major in exercises!"

Although he was shocked in his heart, Hou Shisan did not dare to slacken his mouth, fearing that Li Dong would shoot out from the branches with a knife, which would directly result in him.

"I have seen His Majesty the Thirteenth Prince, the subordinate is the royal guardian, guarding you under your orders."

Hearing this, Li Dong didn't let his guard down.

He pulled the branch away from Hou Shisan's neck, and the whole figure flashed, and he was a few feet away from Hou Shisan, but it happened to cover Hou Shisan within the scope of his sword energy.

Afterwards, Li Dong had a murderous look on his face, and asked Hou Shisan indifferently:

"Hou Thirteen, where's your identity token?"
