Tianchen didn't know what this thing was called. It was obtained from a human corpse he killed some time ago. There were two of them. I didn't care at that time. One of them accidentally fell to the ground and broke it. But then, something that surprised him happened.

Originally he was in an alley, but when the bottle broke, a large ball of green gas emerged and condensed around for a long time. Shortly after the ball of gas emerged, a large number of footsteps rushed towards them. There was no need to think that those who could run so blatantly in the end of the world would be zombies.

Tianchen was frightened at that time. There were so many zombies that he could not deal with alone. He was so angry that he almost cursed. However, when he was about to give up and fight to the death, a scene that shocked him happened.

Although all the zombies rushed towards him, they all turned a blind eye to him, but instead rushed into the green gas without hesitation.

"Sizi!~~~"

As soon as the zombies entered the green gas, the sizzling sound kept ringing. As the sizzling sound was recalled, the zombies kept making roars of pain, and finally fell to the ground and died unconsciously.

Tianchen didn't know what this was, but he knew that when dealing with zombies, this thing had miraculous effects. Even if it was dead, the zombies would still not come out of the green gas. It can be seen that this thing was simply the nemesis of zombies.

Originally, Tianchen didn't want to expose his thing. His idea was that if he could study the components of this thing, then the Tianchen Gang would become the master of this end of the world in the future.

Of course, he couldn't take out the current situation, because if he had no life, the dominance of the matter would be nothing to him.

"Hmph! Go to death!"

Seeing the zombie rushing towards him again, Tianchen showed a hideous face, and the green bottle he was holding in his hand fell heavily at the zombie's feet.

"Pu!"

The bottle shattered in response to the sound, and a large ball of green gas instantly spread around.

"Roar!~~~"

The first thing that was overflowing was of course the second-grade zombie that was closest to it. When the gas surrounded it, it only heard the roars from his mouth and kept coming out, and anyone could feel the pain.

"Ho huh huh!~~~"

Not only the second-grade zombies, when the green liquid overflowed, all the zombies around them put down their opponents. Even if the knife slashed them, they also ignored them and rushed into the green gas firmly.

A burst of pain roars kept coming, and everyone opened their mouths in surprise and looked at the scene in front of them. They were on the verge of dying just now, but now they watched the zombies rushing towards the green gas like suicide, constantly pouring into the green gas. No matter how they look, they have a strange feeling.

Bai Cen, who was about to take action, also looked at everything in front of him in surprise. His heart was no less shocked than others.

"What the hell is this? Why did the zombies seek death so desperately?"

It can be said that no matter what the green gas is, Bai Cen has become curious about it. He wants to know what the function of this thing and why the zombies are desperate. So Bai Cen stared at the green gas for three seconds without blinking.

Purification gas: viruses, second-level first-class items, are effective against all zombies below level 2. Once the gas is released, zombies within a certain range will be attracted and killed by the purifying virus produced in the gas.

"It's actually a second-level item. This Tianchen is really a waste of money!"

Bai Cen was very angry, and the consequences were very serious. Second-level items were second-level items. Although they were only the lowest-level items, if they were to be exchanged, how much energy can they exchange for, and how many big meals can they eat.

Bai Cen, who became more and more angry the more he thought about it, wanted to walk to Tianchen immediately, and gave him a few big mouths and let out a good slap. He had tried it just now, and using the redemption function was not easy to use the green purification gas in front of him.

Given that Tianchen was too far away from him, Bai Cen had to vent his anger, and not far from Bai Cen, there was such a person who could vent his anger on Bai Cen.

The murderer, he was scarred at this time. Although all the zombies had been eliminated, Bai Cen still decided to take action. To be honest, if it were normal, Bai Cen would definitely hesitate if it was for Bai Cen to deal with Tianchen and the other two alone. After all, although the strength of the murderer and the Crazy Doctor is average, it would be different with Tianchen, who is only slightly inferior to him.

But that was normal after all, and it was different now. The three of them were all seriously injured and their combat effectiveness plummeted. Of course, Bai Cen would not miss such an opportunity, and the murderer closest to him happened to be Bai Cen's target.

Since it has been decided, Bai Cen will certainly not hesitate. While everyone else was looking at Tianchen, Bai Cen slowly approached the murderer's back. When he was only a few meters away, Bai Cen accelerated and stabbed the murderer's back heart with the dragon pattern knife in his hand.

"Puchi!~~~" With a light sound, the Tang sword in Bai Cen's hand stabbed the murderer without any obstacles. However, although it stabbed, the murderer did not die.

It turned out that just as Bai Cen accelerated, he didn't know if he was feeling something. He accidentally looked back and saw Bai Cen rushing towards him. Although he was stabbed, he avoided the fatal injury at the critical moment and only let Bai Cen pierce his arm.

"Ah!~~~"

A scream came out of the murderer's mouth, attracting everyone's attention at the same time.

"Who are you? What are you going to do!?"

The screams alarmed everyone, and the sudden change made everyone stunned. However, the first person to react was the Crazy Doctor. After all, he was closest to the murderer's position. When he heard the dragon-patterned knife piercing the murderer's arm, he had already looked in Bai Cen. So, when the others were stunned, he had already realized something and rushed towards Bai Cen as soon as possible. While rushing, he did not forget to distract Bai Cen's attention.

"Who am I? Of course I am the one who killed you."
