Back in Phantom Sea that day, Li Qing had the fortune to encounter an illusion of an immortal palace, and even personally visited it once. He was very clear about the scene inside.

Just now, he couldn’t see it clearly in the hall, but after coming out, such a distinctive feature made Li Qing recall it immediately.

It was Daoist Patriarch Wuji’s Ascension Heavenly Palace!

Made from the bones and emergence of the Heaven-Devouring Kun Peng, one of the three great ancient Heavenly Yaos, he was born with the power of space and was known as a palace that would never fall.

Apart from the Ascension Heavenly Palace, who else could build such a magnificent palace?

But the question now was, why did Daoist Patriarch Wuji’s palace fall into Lord Chang Sheng’s hands?

The Ascension Heavenly Palace had always floated in the void, and its tracks were ethereal. Throughout the ages, countless capable and loyal warriors had wanted to search for this palace, but they could not even see its shadow.

This treasure was truly too mysterious. It was so mysterious that it almost made people think that it did not exist at all. They felt that it was just an illusory legend.

“What exactly is this Lord Chang Sheng’s identity? He has lived from ancient times to the Middle Ages and obtained such a peerless treasure as the Ascension Heavenly Palace. He is truly an amazing figure.”

“The question is, why is he able to live for so long? Could it be that he has truly reached the stage of immortality?”

‘”Impossible. Even Daoist Patriarch Wuji can’t do this. How could Lord Chang Sheng be more powerful than them?”

“Could it be that Lord Chang Sheng is Daoist Patriarch Wuji himself?” Li Qing suddenly thought of this possibility and was shocked by this guess. His entire body trembled and his scalp went numb.

Could it be that Daoist Patriarch Wuji did not die at all, but survived the tenth level of heavenly tribulation, so that he could live forever?

Otherwise, it was impossible to explain why Lord Chang Sheng had lived so long! Only after crossing the tenth lightning tribulation and reaching the supreme Eternal Realm could one obtain the power of longevity.

Moreover, Lord Chang Sheng also controlled the Ascension Heavenly Palace. This was something that belonged to Daoist Patriarch Wuji, and it seemed to be another layer of evidence.

However, when he thought about it carefully, he felt that something was wrong.

If it was really Daoist Patriarch Wuji himself, why would he need to sneak into hiding like this and appear in front of the world openly?

With Daoist Patriarch Wuji’s strength, no one could pose any threat to him. Moreover, he was the founder of the Dao Sect, so it was impossible for him to betray him.

He had the highest prestige in the world. He could do anything openly and openly. There was no need to hide it so deeply.

“Could it be that you care about your reputation? Are you afraid of being called a demon?” Li Qing thought of another possibility.

With what Lord Chang Sheng was doing, he was indeed like a madman. He studied life, transformed it, and even wanted to create a perfect half-human half-demon form…

If these things spread out, it would inevitably reduce the reputation and affect the perfect image in the eyes of the world.

However, this reason was somewhat far-fetched.

The study of life and the pursuit of longevity could not be said to be the evil path of a demon. For the sake of longevity, there were many powerful beings who had tried all sorts of research in history, and even crazier experiments had been done. It was not a shameful thing to do.

Didn’t they work hard to cultivate, and their ultimate goal was to live forever?

To give up so many favorable conditions for the sake of this mere nothingness would be a loss no matter what. With Daoist Patriarch’s intelligence, it was impossible for him to make such a choice.

Considering all these factors, this Lord Chang Sheng could not be Daoist Patriarch Wuji himself.

Who could it be?

Since he was able to control the Ascension Heavenly Palace, he might have some connection with Daoist Patriarch. Could it be that he had secretly taken in a disciple, or was it some inheritor from Limitless Main Hall?

However, these identities weren’t enough to explain why Lord Chang Sheng didn’t dare to reveal himself in front of others.

Since he didn’t dare to reveal his identity in front of others, there must be a fatal flaw in his identity. It was precisely because of this flaw that even though his strength had reached such a tyrannical level, he still carefully hid it.

“Forget it, we know too little about the ancient times. There’s no point in guessing like this!” Li Qing stopped guessing.

At this time, Lord Chang Sheng was bringing Jin Wu to a secret room.

Looking up, one could see that this secret room was actually filled with all kinds of bottles and cans, which seemed to be specially used for research.

After passing through this secret room, he entered the next room. There were corpses of all kinds of creatures here, and he even saw several prehistoric species that were extinct in the world.

He continued to walk inside and entered the next room. It was very cold inside, and a cold aura came out from the surrounding walls. Even though it was as strong as Jin Wu, he couldn’t help but feel a little uncomfortable.

This should be a freezing room. There was an ice coffin in the middle, and one could vaguely see a human body frozen inside.

“Why did you bring me here?”

“Do you want to return to human form again?” Lord Chang Sheng asked.

Hearing this, Tai Yi’s eyes lit up, “Really?”

“This is simple. As long as I give you a Form Transformation Fruit, you can start over.” Lord Chang Sheng took out a fruit and handed it to him.

He was the cultivator of the Form Transformation Fruit, so he naturally had many of these fruits.

Tai Yi immediately picked it up. Although he didn’t know what Lord Chang Sheng was up to, he still chose to start over without hesitation.

He swallowed the Form Transformation Fruit into his stomach in one bite, and then the scene of the demonic beast transforming into a form appeared again. The feathers began to fall off, and countless heaven and earth energy surged over, gathering into a golden cocoon.

After an unknown amount of time, the golden silkworm cocoon broke open and a human figure crawled out of it.

Lord Chang Sheng nodded slightly, “Very well, after the transformation, I will use your body to do an experiment.”

“What experiment do you want to do?” Tai Yi stared vigilantly at the other party.

“Relax, don’t resist!” Lord Chang Sheng did not explain anything. With a wave of his hand, he controlled Tai Yi’s body and moved it onto an ice bed.

“It’s so cold!” In an instant, he felt a chill gushing in from the ice bed, and his body seemed to be frozen stiff.

“Right now, I am nothing but a fish. I have no power to resist. I can only hope that the other party will not do too crazy experiments.” Tai Yi closed his eyes helplessly.

There was nothing he could do. Lord Chang Sheng’s strength was truly too terrifying. Even a tyrannical Demon Saint could not defeat one of his fingers.

“It might be a little painful next. You should be mentally prepared.” Lord Chang Sheng’s voice came.

As soon as he finished speaking, Tai Yi felt an unbearable pain coming from his abdomen. Even someone as determined as him couldn’t help but let out a miserable scream.

‘”Ah–” He tilted his head and fainted.

After an unknown amount of time, when he woke up, he discovered that his entire body was soaked in a green liquid, filled with life energy.

“Very good, perfect fusion!” Lord Chang Sheng’s voice rang out.

“What did you do to me?” Tai Yi asked.

“Nothing much, just transplanting the human dantian onto you.”

“How is that possible! How can a human’s dantian fuse with a demonic beast?” Tai Yi said in disbelief.

“If you don’t believe me, you can examine it yourself. Not only is it your dantian, there are also many human organs. As long as it’s something you lack, it’s all inside.”

Tai Yi hurriedly checked his body, and as expected, he could faintly feel the existence of his dantian in his abdomen.

“Impossible! Humans and demonic beasts are two completely different races. How could organs fuse together? You must be lying to me!”

“Why would I lie to you? Although there was indeed a violent rejection reaction during the fusion process, I am the only Lord Chang Sheng of all time. How could an omnipotent god not be able to solve such a small problem?” Lord Chang Sheng’s face was filled with pride.

The truth was right in front of him. It was impossible for Tai Yi not to believe that the limbs and organs of humans and demonic beasts could actually fuse together! This was simply heaven-defying!

“What is this green liquid?”

“This is the essence of life. It’s extracted from the Divine Tree of Life. Even if you only have one set of bones left, you can regrow your flesh and blood.”

“What exactly are you doing this for?”

‘”Isn’t this obvious? I installed a dantian for you to cultivate. I really want to see how far a transformed demonic beast can cultivate!”

“You are a madman! How can a demonic beast cultivate true energy like a human? This is going against the heavens, and it will suffer the wrath of the heavens!”

“Nothing is impossible in front of me!” Lord Chang Sheng smiled.

“What if I refuse?”

“No one can refuse my request from Lord Chang Sheng. You can only obey. I have wasted so much resources on you. Do you think there is still room for manoeuvre?”

“I really don’t want to be your test subject! I just want to be an ordinary person quietly. Will you please let me go?”

“No way! You only have two choices. If you cultivate true energy according to my requirements, I will let you go. Otherwise, you will be locked up here for the rest of your life!”

“Will you really let me go?” Tai Yi’s spirits lifted.

“When did what I, Lord Chang Sheng, said not count?”

“I hope you can fulfill your promise!” Tai Yi could only choose to trust him.

“The right choice!” Lord Chang Sheng took out a book and said, “Next, you can cultivate this cultivation technique.”

Tai Yi took it and looked at it. It said, Undying Undying True Devil Gong!

“It can’t be?” Li Qing was stunned. Why did the Demon Ancestor’s cultivation technique appear in Lord Chang Sheng’s hands? He couldn’t help but wipe his eyes, wondering if he was wrong.

Demon Ancestor’s peerless technique has never been spread outside. Where did this fellow get True Devil Gong?
