But in the blink of an eye, the demon king who read out the document was killed by Tang Zhen at an incredible speed.
The headless corpse fell to the ground, but turned into fly ash in the blink of an eye, leaving no trace.
It is really unbelievable that a powerful and dignified demon king was killed like this.
The four demon kings next to them were shocked. They never expected that such a change would happen.
Even they can't kill a demon lord casually, let alone a human monk!
Although he didn't believe that this was Tang Zhen's doing, the fact was before his eyes that the demon king had indeed been killed by Tang Zhen.
Obviously something big went wrong in this mission. This Tang Zhen must not be let go!
"Tang Zhen, go to hell!"
Without any hesitation, the four Demon Lords launched attacks at the same time, heading straight for Tang Zhen in the center.
In an instant, the situation changed, and the demonic energy rolled over the sky. Originally, the sky was clear and clear, but at this moment, it was completely invisible.
In this darkness, there is a deadly murderous intention, heading straight for Tang Zhen.
The four demon kings had different methods, but each one was more powerful than the other. They clearly wanted to take Tang Zhen's life with one move.
At this critical moment, Tang Zhen rushed forward without dodging.
To a demon hunter, a strong man at the level of a demon king is like a terrifying natural disaster, an existence that cannot be resisted.
But to Tang Zhen, these demon lords were nothing more than bared-toothed puppies, posing no threat at all, and even felt a bit ridiculous.
His current state is far superior to that of the four Demon Lords. Even if he is besieged from all sides, he still feels like strolling in the courtyard.
The sword flashed and cut through the boundless darkness. One of the demon kings suddenly screamed and retreated quickly.
It rushed at the front, so it was naturally the first to be attacked. Tang Zhen cut most of its body open with a single slash of his knife.
The injured Demon Lord was frightened to death. While retreating quickly, he was still trying desperately to repair his body.
It was only then that it discovered that there was a strange force at the wound, trying desperately to prevent the wound from healing.
Upon noticing this abnormality, Demon Lord was filled with fear and looked at Tang Zhen with even more fear.
If this situation continues, let alone killing Tang Zhen, he may not even be able to protect himself.
"This Tang Zhen is too weird. We are no match at all. Don't act rashly for the time being!"
Seeing that Tang Zhen instantly killed one Demon Lord and then seriously injured another in the blink of an eye, the expressions of the other three Demon Lords changed drastically.
They warned their companions, covered the retreat of the injured demon king, and launched another attack.
It's just that this wave of attacks is no longer for killing the enemy, but for self-protection, lest Tang Zhen get closer.
Unexpectedly, at this moment, a scream suddenly came from the distance, coming from the injured demon king who was retreating.
When the three Demon Lords looked back, they saw that the Demon Lord's body had fallen to the ground, and there was a person standing next to him. It was Tang Zhen who had been surrounded by them before.
There was still blood dripping from the blade of the sword, and the head was full of ferocity and terror.
It didn't expect that it was the farthest away, but was the first to be killed. It must have been extremely aggrieved before it died.
"Damn it, when did he get to the back?"
The three Demon Lords were shocked. With their strength, they didn't even notice how Tang Zhen moved his position. This was simply life-threatening.
Such a monster appeared among the human race, and they had no idea about it before. They were simply raising tigers to cause trouble.
If this serious danger had been discovered early, he would have been cut into pieces at all costs.
It was too late to regret at this time, Tang Zhen had already become a traitor, and the demon clan was probably about to suffer a catastrophe.
While feeling fear, they also suddenly realized that this mission might not be completed successfully.
"The situation is not right, let's retreat first!"
The three demon kings looked at each other and without any hesitation, they immediately left the battlefield.
Although they may not be Tang Zhen's opponents, they are quite good at escaping, and they are heading in different directions. Even if Tang Zhen wants to chase them, he can only chase one of them.
Unexpectedly, not long after they rushed out, they found that the surrounding space had been completely blocked, and the blood-red mist completely blocked their way.
"Break it open and get out!"
Without any hesitation, the three Demon Lords attacked the red mist at the same time, trying to create a way to escape.
Unexpectedly, after the attack landed on the mist, it was like a mud cow entering the sea, without any reaction.
Seeing this scene, the three demon kings were shocked and angry. If the red mist barrier could not be penetrated, none of them would be able to escape.
Just as they were preparing to continue their attack, they heard a gust of wind behind them, which was clearly the sound of a sword piercing the air.
"Someone is attacking!"
The three Demon Lords were shocked and turned around to check at the same time. They all thought it was Tang Zhen who was attacking.
As a result, there was nothing behind him. Where was Tang Zhen's figure?
Just as they turned around, ferocious tentacles suddenly appeared in the red mist and headed straight for the backs of the three demon kings.
The attack came quickly and urgently, and the three demon kings were caught off guard, and were directly pierced through the back of the heart by the tentacle.
The three demon kings who were attacked roared angrily, and all turned around to try to get rid of the tentacle attack. The panic in their hearts could no longer be suppressed.
At this moment, they even regretted that they should not have come so recklessly, otherwise they would not have encountered such a dangerous situation.
It's just that it's too late to regret now. Now they have been injured at the same time. If there is any further hesitation, they will definitely die today.
What frightened them even more was that the tentacle was like a living creature. After piercing their bodies, it sank directly into their bodies and disappeared without a trace in an instant.
It was as if a group of strange insects had entered the body, scurrying around in their meridians and blood vessels, as if they would burst out of the body in the next moment.
The three demon kings became more and more panicked. While they were frantically suppressing this strange power, they were still trying to find a way to escape from this place.
But the barrier is unbreakable, even if they try their best, they can't break it even a little bit.
The three demon kings who were in a hurry had crazy looks on their faces. While they were unable to escape, they thought of Tang Zhen again.
The key to escaping from this place is probably still with Tang Zhen.
But looking around, there was no trace of Tang Zhen. It seemed that he had disappeared long ago.
But the three Demon Lords could clearly feel that there seemed to be a pair of cold eyes staring at them, without any emotion in their eyes.
"Tang Zhen, get out of here!"
Shocked and angry, the three Demon Lords shouted to the sky, trying to find any trace of Tang Zhen, but there was no trace at all.
The strange power in their bodies continued to explode, making them more and more panicked. At this moment, they were scurrying around in this space like ants on a hot pot.
Not long after, the strange power completely erupted, and the three demon kings couldn't bear the pain, and they all let out shrill wails.
Tentacle-like filaments emerged from the bodies of these demon kings. While growing crazily, they also absorbed the essence and blood of these demon kings at an extremely fast rate.
But in the blink of an eye, they already resembled skeletons, and their movements became slower and slower.
The three demon kings noticed the drastic changes in their bodies and went completely crazy. They tried their best to eliminate the abnormalities in their bodies, but to no avail.
But the methods Tang Zhen used were beyond the ability of a few demon kings to break. When he provoked Tang Zhen, he was already doomed to death.
In despair and regret, the three demon kings turned into withered bones and fell to the ground, and then three blood-colored crystals flew up.
Tang Zhen grabbed the blood crystal casually, glanced at the dead bones on the ground coldly, and disappeared in the next moment.
