Boom, the door opened, and the three of them walked out, outside, Huang Yi and the Holy Demon were waiting.

"Huang Yi, go and arrange a place for the Holy Devil to live, we still have something to discuss with Zhou Tian. ”

The burial lord commanded.

"Yes!"

Huang Yi responded, looking at the direction of the three of them, his pupils shrank slightly, as if he thought of something, but no one noticed his abnormality.

Following the two big guys, he turned left and right in the border prison, and came back to the hall where Huang Yi came to at the beginning.

The door of the hall opened, and the three of them walked in, this is also a very huge hall, on top of the bronze giant pillar, there is a black stone dragon, and there are two thrones side by side.

"Are you ready?"

The undertaker asked.

"Hmm. ”

Zhou Tian nodded.

Then, the burial master and the prison master glanced at each other, and with a wave of their big hands, wisps of light appeared in the hall, and runes appeared on the ground of the hall, which were extremely mysterious, and then filled the entire hall.

"What you will see is the deepest secret of my prison!"

Zhou Tian's heart is full of expectations, and these two big guys need to open the place at the same time, and I don't know what it will be.

The runes were complicated to the extreme, and with a flash of light, everything disappeared, and the hall became empty.

When he reappeared, Zhou Tian was already in an unknown space.

The space was filled with a myriad of instruments that had never been seen before.

The light was overflowing, the runes flickered, and in what resembled a glass tube, a strange black object the size of a fingernail, exuding a monstrous death aura, but it was all imprisoned in the glass tube.

A young man's pupils flickered with golden light, meticulously recording something, and then, stretched out a little on the glass tube, and in an instant the entire glass tube was covered with golden runes, and then, the black object inside was instantly wiped out.

This seems to be an experiment, if you ignore the young man's cultivation, but that young man is clearly a Tianzun-level existence.

And in this space, there are at least dozens of such people, and this number shocked Zhou Tian extremely much.

"Only those at the level of Heavenly Venerable are qualified to know the true secrets of the Border Prison. ”

The Burial Master explained that the people here were extremely busy, and even when they saw the Burial Master and the Prison Master, at most they just nodded their heads and looked at Zhou Tian by the way, but they went about their own business.

"This number of Heavenly Venerables..."

Zhou Tian said with some surprise.

"Don't be surprised, the border prison is very special, and it is not difficult for Tianzun here. ”

The prison master said with a little meaning.

Zhou Tian instantly understood that there should be a special method in the border prison to give birth to Tianzun.

"Let's go, I'll show you Zero. ”

The burial master led Zhou Tian to a black sphere and nodded to the person in charge on the side.

Immediately, two black rays of light enveloped them, and Zhou Tian felt a sense of weightlessness coming, and then the feeling of being turned upside down.

When I came back to my senses again, I was already in a dark void.

"Look down. ”

Next to him, the voice of the burial master came, his body was a little illusory, it seemed to be just a projection, and Zhou Tian's own was the same, and he couldn't feel the existence of substance.

When Zhou Tian heard this, he looked down, his pupils contracted, and he saw a huge and boundless humanoid body and a man below, slowly fluttering in the void.

His skin was black, his face was peaceful, and his body was plagued by various void storms, but not a single body hair could make it flutter.

There are some places that make Zhou Tian dare not look directly, which is comparable to an ancient mountain range.

Just a fist was as huge as a star, because just now, a star with a glittering silver light rubbed against this body, and it exploded in an instant.

And there is a black dot at the center of its eyebrows and heart, and if you look closely, what kind of black dot is it, it is clearly a border prison.

"This is Zero. ”

The voice of the undertaker rang in his ears.

"Countless years ago, the astral plane was not systematic, but there were also some powerful worlds that gave birth to some powerful characters, and the creator of the Border Prison was such a figure, he encountered this body while exploring the Void, and this was what Zero looked like at that time. ”

"At first, the senior just wanted to use this body to explore the way forward in cultivation, but after being by Zero's side for a long time, he suddenly found a problem, this body was giving birth to divine intelligence. ”

"This level of physical body is really terrifying, even a body will give birth to a sanity after countless years. ”

"But this body is essentially dead, and the body is full of life, and if a new mind is born, it will also be eroded, and it will become a machine that only knows how to kill, destroying everything, including the world that came before it. ”

"So the Border Prison came into being, and used all the means to stop the inhibition, and Zero's body was revived. ”

The funeral master briefly introduced that there are many questions that have not been explained, but there is no need to explain them too carefully.

With a wave of his hand, the distance was instantly drawn in, and they approached again, and came to the heart of Zero, a huge heart, which was no longer beating, but there were several needles inserted into it, and it was not correct to say that the needles were incorrect, because each one was a hundred feet thick.

But such a thick "needle" can't draw a drop of blood.

"It took us countless years and countless costs to extract a drop of essence blood from it and make my funeral book. ”

The undertaker said.

I see, such a strange and rebellious burial book can only be created by this level of essence blood.

Boom, a shock came, and before Zhou Tian could react, they had reappeared outside of Zero.

I saw that in front of Zero, there was a world barrier, and there was a world in front of it.

However, before Zhou Tian could speak, Zero rushed straight into it, without any suspense, the world barrier was shattered, but when it was weird, every wisp of world origin and the breath of destruction were absorbed by Zero, and there was nothing left in this world.

"We can only adjust the drifting direction of Zero slightly, and there is nothing we can do about a world like this. ”

The undertaker explained.

"Then what is the purpose of inviting me? ”

Zhou Tian was silent for a long time and spoke.

The burial master glanced at Zhou Tian, waved his hand, and the sky swirled again, and they returned to that space.

"I'm going to break through half-step creation. ”

The undertaker said.

"Actually, I just wanted to break through the half-step cultivation last time. ”

This is a bit surprising, Zhou Tian raised his eyes and glanced at the burial master.

"The Funeral Book is very special, I can use him to break through the half-step creation and then comprehend the power of creation. ”

The undertaker continued.

"But there is a problem, the funeral book has a strange connection with Zero, which is likely to be a fuse, detonating the increasingly active Zero, directly giving birth to consciousness, which is very troublesome and we can't deal with it. ”

"I need you, or Dao Ancestor's seniors, to take action to prevent this from happening. ”
