When Tai Yi saw the name of this technique, he was also very puzzled, “Undying Undying True Devil Gong seems to be the ultimate technique of the Demon Ancestor. How could you possess it?”

“Don’t worry about this. Just follow my instructions and cultivate.”

“But this is a devil technique. I don’t really want to cultivate it, so I feel that it’s a bit inappropriate.” Tai Yi shook his head and asked, “Why don’t you just give me the Righteous path technique?”

“You’re a demonic beast. What’s the difference between cultivating Righteous path and Diabolism? Why are you considering so much?”

‘”If someone finds out about cultivating the Diabolism technique, it is inevitable that a righteous person will come out to eliminate the Devil Guard. Perhaps someone will cut off his head in his sleep one day. Isn’t that just unjust death? It would be safer to cultivate the Righteous path technique.” Tai Yi wasn’t stupid either. After living in the human world for so many years, how could he not see the world pattern?

“In today’s world, the world is in chaos. The ten palaces of the Dao Sect have long been beaten to pieces by the Five Emperors. How can they meddle in this matter? As long as you are careful, there will be no problem.”

“But …”

“Enough!” Emperor Longevity didn’t wait for him to say anything else and immediately interrupted, “I’m not discussing with you, but I’m giving you an order! You have to cultivate, you don’t have the right to choose!”

After saying that, he disappeared into thin air.

Tai Yi sat dumbfounded in the secret room, his mind filled with thoughts. There were too many things that happened today, so it was necessary to get a clear idea of what was going on.

“No matter how crazy the experiment is, leaving alive is my goal.”

“From the looks of it, if I want to leave this palace, I have to obey Emperor Longevity’s arrangements to cultivate this Undying True Devil Gong.”

‘”There’s no need for someone at his level to deceive me. If he says that he will let me out, he will definitely let me out. Of course, the prerequisite is that I have to survive the experiment!”

“There must be something fishy about him arranging for me to cultivate this devil art. Unfortunately, I can’t guess his purpose. He’s right. I have no other choice. I have to cultivate, or else I’ll be trapped here forever.”

“Now, let’s see what kind of secret this Devil Ancestor’s ultimate technique hides!”

He opened the book and read it carefully. The words on it also entered Li Qing’s eyes, causing him to be stunned.

The reason for that was because the contents of this book were very different from the original version of True Devil Gong that he cultivated.

It could be seen that the content of this book was very similar to the original True Devil Gong, and about sixty to seventy percent of its meaning was actually the same.

However, they were only identical in meaning, but completely different in the way they chose words and sentences.

It gave Li Qing the feeling that it was a fake!

It was definitely not a possibility of completing the remnants of the book. The difference in language style was clearly the work of two different people.

‘”So it’s not the real True Devil Gong. The ultimate technique of the Demon Ancestor hasn’t been leaked out. That should be a counterfeit from Lord Chang Sheng. What is his intention?”

“To be able to imitate it to sixty to seventy percent similarity, one must at least have a certain understanding of this technique, or simply have personally witnessed the might of True Devil Gong before being able to create it.” Li Qing guessed to himself.

“However, if we lose a millimeter, it will be thousands of kilometers away. In the end, the imitation is somewhat inappropriate, and there are many key points that are far from each other.”

If Demon Ancestor’s unique technique was so easy to copy, then it wouldn’t have been lost for so many years.

A supreme expert had reached the peak of a certain path. If outsiders did not reach this level, how could they create a peerless technique of this level?

Lord Chang Sheng’s strength was already quite good, but he still hadn’t reached this level, slightly inferior.

Moreover, his research on demonic arts didn’t seem to be very deep. He could be said to be an outsider, so this true demonic art could only be said to be a semi-finished product.

Taking out a semi-finished product for Tai Yi to cultivate was definitely not that simple.

A few days later, Tai Yi finally finished reading this technique, fusing the meaning behind it, and then began to cultivate. However, the process was not so smooth.

The idea is good, but the actual result is different. Even if he transplanted a human dantian, could he really cultivate?

The answer is no.

At the beginning, Tai Yi had indeed successfully cultivated a strand of True Qi, but very quickly, this strand of True Qi raged in his body, causing his meridians to shatter in large quantities.

Lord Chang Sheng’s figure flashed out and immediately forced out the strand of True Qi in Tai Yi’s body. Then, he put Tai Yi into the green solution and repaired his broken body.

“With a dantian, is it still not enough?” Lord Chang Sheng frowned.

But he is not so easy to give up. Failure is the mother of success. People who do research like to absorb experience from failure and improve it.

Over the next few days, Lord Chang Sheng spent a large amount of treasure resources to completely transform Tai Yi’s meridians, making them more suitable for accommodating true energy.

“Try cultivating again.” He said.

Tai Yi tried again and smoothly cultivated his True Qi. Sure enough, there weren’t any problems.

This strand of True Qi circulated through his meridians, traveling along a specific path for a whole day before converging into his dantian.

As a result, he had only just entered his dantian when he became frantic and exploded.

“Not good!” Lord Chang Sheng’s expression changed. He immediately reached out and sealed Tai Yi’s dantian, forcing out this strand of rebellious zhenqi.

In the following period of time, it was another transformation to solve this problem…

Tai Yi has been in Longevity Palace for three years since spring and autumn. During this period of time, he had gone through countless attempts, and every time, there would be all sorts of problems. Shattering his meridians was a common occurrence, and his dantian had exploded several times. There was even a situation where he was possessed by a devil, and he almost lost his life.

Fortunately, with Lord Chang Sheng watching from the side, it was difficult to die. He always had all sorts of miraculous methods to rescue Tai Yi at a critical juncture and completely repair his body.

In this way, he continued to fail, to transform, to fail again, to transform … Tai Yi’s body became more and more perfect and evolved in the direction of humanity.

In the end, he overcame his last failure and finally smoothly embarked on the path of cultivation.

Feeling the abundant zhenqi in his body, his luck wasn’t stagnant and unimpeded. It was like an innate talent. This made Tai Yi breathe a sigh of relief in his heart.

Finally succeeded, this damn day should be over, right?

In these countless experiments, not only did he have to endure physical torture, but his mind was also on the verge of collapse. If he stayed for a few more years, he might go crazy.

“Can I leave now?”

“Cultivate for a while longer. Let me see if there will be any problems.” Said Lord Chang Sheng.

The smile on Tai Yi’s face stiffened and he sighed in his heart, “I can only endure for a while longer. I hope that he can fulfill his promise and let me go as promised.”

Another year passed. After observing for this period of time, there were no more problems with Tai Yi’s body, and his cultivation of True Qi was normal.

Lord Chang Sheng had invested countless resources in him, allowing Tai Yi’s cultivation to soar to the Houtian 7th layer in a short period of time. It could be said that his progress was rapid.

In the end, nothing happened. Lord Chang Sheng fulfilled his promise. After confirming it, he really let him leave the Immortal Palace.

A wave of spatial ripples came, and Tai Yi could only feel the heavens and earth spinning, instantly appearing in a desolate mountain range.

He raised his head and looked at the sky. There was no trace of the Immortal Palace anymore.

“Really? Am I dreaming?”

Looking at the surroundings, after experiencing countless painful experiments for several years, he once again returned to the mortal world, and a feeling of being from another world surged into his heart.
