At first glance, these skull walls are a bit like a piece of charred cheese.

The exposed black skull, which was corroded by the air into dotted pores, mixed with the earth, was dry and jerky to the touch. The Nirvana Demon Emperor slowly lingered with evil power at his fingertips, moving along the veins of the skull wall, and gradually sensed the power inducement from the depths of this wall, which was a power that ordinary people could never perceive, and it was a secret passage to communicate between the two intersecting spaces.

The Demon Emperor couldn't be sure if the wall he had chosen was the Netherworld Void that Daozhen used to seal the Dark Realm, but he didn't care about that, even if it was Daozhen's trap, he was interested in entering it to see if the enemy he had been waiting for for a long time would disappoint him. Even if there are no traps, it's all for nothing, and you can re-enter the next skull wall.

The Netherworld Void slowly opened, and the Nirvana Demon Emperor stepped into it, bursts of chaotic air currents poured towards him from all directions, the colors of these air currents were not common colors in the world, they looked mysterious and weird, and everything here was also in a form without any substance. Everything seemed a little ethereal, and air didn't exist in this space, so even if someone found the entrance to the Netherworld Void and entered here, it would still disappear in a short time.

And here, although it is the intersection of the three realms, the closest place is the holy area.

The Sacred Realm, like the underworld and the human world, is one of the Three Realms of the present world, and it is also the environment in which the supreme administrator of the entire world lives. From the perspective of human science, they call the outer space of the Sanctuary the universe, and the universe is actually just a part of the Sanctuary, a circular space, if human beings really have a way to break through here, they will also fall into an endless cycle, unless with the help of special forces such as aura or evil power, it is possible to break through the confinement of the enchantment and come to the most real place in the Sanctuary.

The Netherworld Void is adjacent to and closest to the Sanctuary, and as such, it has some of the qualities of the Sanctuary, which has the infinite power of human science, as well as cosmic rays that can kill living beings in an instant, and the intense radiation will cause any living organism that inadvertently enters it to die.

In fact, the so-called science and superstition are only separated by paper in this world, and demons and monsters can also be explained by the energy theory of human beings, and the aura and evil force themselves are also a kind of advanced energy that does exist.

The strong radiation will not cause special harm to the Nirvana Emperor, but what makes him feel a little uneasy is some other things hidden in the Netherworld Void, this guy's size is very large, so that the Nirvana Demon Emperor has an illusion that he is also in the body of this guy. This guy seems to be very small, as if it has broken down into countless tiny particles that linger around him.

But either way, this guy is very close to himself.

"Come out." The Demon Emperor said in a deep voice.

After a while, a faint voice echoed in the void:

"You're Yu Changsheng."

The sound was constantly distorting and changing, making it impossible to determine its original state, and even in such a vacuum, it could still be transmitted, but it sounded a little long and treacherous, like an owl howling.

"Well, if Dao Zhen just sent you over to ambush me, then he really underestimated me." The Demon Emperor was a little disappointed.

Although he hadn't seen the form of the enemy yet, the Nirvana Demon Emperor had a full grasp of this battle, and this guy's murderous aura was almost non-existent, even as if he was standing in front of a weak sheep who had just given birth to cubs.

"No, he just asked me to trap you." The other party replied.

The Nirvana Demon Emperor was not surprised, he had already found that the entrance had disappeared, as early as when he had just entered this space, the entrance had already disappeared, and when this guy who made a strange sound appeared, he felt that kind of atmosphere similar to imprisonment, which showed that in fact, the entrance did not disappear, but when he entered the Netherworld Void, this guy was likely to have trapped himself in its body.

"So, do you still think you can trap me?" The Nirvana Demon Emperor smiled and stretched out his arms, and majestic evil power emanated from his body.

The messy and interlaced colorful lines in front of him suddenly all flew out in the opposite direction, and the Nirvana Emperor was shrouded in a thin layer of darkness, this color was an unfathomable darkness even in this dark void without any light, making people feel that they couldn't extricate themselves just by seeing this darkness. Any substance, even just gas, can be irresistibly timid in the face of such darkness.

The Nirvana Emperor shuttled through this chaotic space at great speed, and set up evil markers along the way, but he always returned to the original point every once in a while, and although he moved freely and unimpeded, he fell into some kind of loop.

The Nirvana Demon Emperor stopped, a black ghost fire condensed in his hand, he had lost interest and was ready to destroy this place directly.

"It seems that if I continue to let you go, maybe you may really escape from my body, but as I said, I am only responsible for trapping you, and as for how to deal with you, it is not my business." The other party replied calmly.

"Oh?" The Nirvana Emperor raised his head with great interest, and the ghost fire flickered with a cold glow.

This time, he had already judged by the sound where the creature who had imprisoned him came from.

Above his head, there was a dark sphere that seemed to be nothing, although this sphere was difficult to detect, but it was obviously different from other parts of the space, and the Demon Emperor judged that this dark sphere should be the heart or head of this guy.

The Nirvana Emperor retrieved part of the memories in Yu Changsheng's brain and found that the guy who trapped him should be the kind of high-level demon called the Dome Corpse Bag.

Legend has it that after Pangu opened the world, the corpse turned into mountains, rivers and lakes, and everything in the world. And some of the corpses did not remain in the world, but were taken away by the ancient goddess Nuwa. And the bag used to take away Pangu's corpse is this dome bag. The corpse bag is formless, but it has its own consciousness, and after breaking away from the control of its master, it has become an independent evil ghost, and has caused trouble in the world for a long time. When it appears in a certain place, that area will suddenly be hit by a terrible storm, and then the entire area will be swallowed by this evil spirit and disappear. Later, it was not until he was subdued by a certain ghost hunter that no trace of this evil ghost could be found in the world. But because of the scarcity of these demons, there are very few records of their weaknesses and habits, except that the legend has it that the people who are sucked into them will never be able to come out unless they find the heart of this guy.

The Nirvana Emperor took his eyes off the black orb and remained silent, and when the power in his hand was accumulated, he was ready to suddenly attack the black orb above.

"Dome Bag, you're a good evil ghost, come with me, I can spare your life." The Nirvana Emperor said.

"No, it's not just that I don't want to, but I can't either, the ghost hunter's contract spell can't be broken, and if I have a way to break it, it's absolutely impossible to fight a madman like you." The Dome Bag immediately refused.

"It's good that the Dark Realm doesn't seem to be able to fit a guy as big as you." The Nirvana Emperor muttered, in fact, he wanted to take the opportunity to accumulate strength.

However, just as the Nervana Demon Emperor was preparing to attack, in this illusory space, an astonishing aura suddenly appeared, as if an active volcano was erupting without warning, and this powerful force produced terrifying fluctuations in the space.

This power made the Nervana Emperor a little excited, but at the same time, he realized that he couldn't waste too much time with this corpse bag, so he immediately threw the ghost fire in his hand into the air, and at the same time he quickly jumped backwards.

"Shattering Flame!" The Demon Emperor shouted angrily.

The black ghost fire slammed into the darkness at an astonishing speed, exploding instantly, and the sparks that flew out were all dark blue like lightning, and after the darkness was attacked by the ghost fire, a series of free cracks appeared on the surface.

But what the Nirvana Emperor didn't expect was that the damage caused by his attack was limited to this, and those cracks actually healed slowly, and finally swallowed and disappeared along with the unquenchable ghost fires on the periphery.

At the moment of the Nirvana Demon Emperor's clone, the terrifying power that suddenly appeared in the Netherworld Void also approached him in a short period of time, and when the Nervana Emperor came back to his senses, a brute fist had already smashed into him.

In this sneak attack, the enemy just threw a very ordinary punch and did not use any weapons.

But as the Dome Bag said, the one who really wants to destroy the Nirvana Demon Emperor is this guy in charge of the sneak attack!

The void burst out with a clear arc of light, but it did not produce a huge roar, and the Nirvana Demon Emperor defended in time, but his right shoulder was still completely shattered by this brute fist, and the strong force destroyed everything along with the space, leaving only a cloud of black smoke.

The Nirvana Demon Emperor's eyes widened, he didn't expect the other party's speed to be so fast, and what surprised him even more was that the enemy in front of him was not a demon, nor a monster, but an ordinary human being.

This human being, in Yu Changsheng's memory, still has an impression.

"Zhang Xiao?" The Demon Emperor said the other party's name.

"Hey, hey, hey...... Little trash, I didn't expect you to become so strong now, but in front of my absolute power, you are still not as good as trash. Zhang Xiao grinned, and the muscles on his body tensed.

Compared with the last time they met, Zhang Xiao's body has undergone even more amazing changes, before his body only suffered the erosion of the two viruses of iron armor disease and zombie virus at the same time, and while maintaining his strength, his physical degree has also been strengthened.

But now Zhang Xiao is not only shining with a steely luster all over his body, but also an indescribable power flowing around him.

The bone claws have turned into steel claws, but the flesh and blood that were originally corroded away cannot be restored, and although the body shape is not as exaggerated as before, every muscle seems to have been tempered and become strong and compact.

The Nirvana Demon Emperor immediately understood that the kind of zombie similar to Queen Hou Xiong that Yu Changsheng encountered before was not a failed infection, but probably existed as an experiment from the beginning. In order to maximize the effect of the Temper Limit Poison Needle, Dao Zhen is likely to find a lot of humans with physiques like Wang Houxiong and Zhang Xiao, and create zombies with independent consciousness but can be controlled by themselves.

"Interesting, have you thought of your last words? If not, I can give you a few more minutes to think about it, because I feel like you're probably the first guy I'll be able to have fun with since I was resurrected. The Demon Emperor's eyes widened and he licked his lips stained with his own blood.

Zhang Xiao's eyelids were slightly raised, and he was surprised to find that although this guy in front of him looked exactly the same as Yu Changsheng, his words and deeds were indeed completely different!

"Trash, you won't have a chance to hear Lao Tzu's last words, because you must have died earlier than me!"

Zhang Xiao said viciously.
