What is the name of this thing, Tianchen doesn't know, it was obtained from the corpse of a human he killed some time ago, there are two of them, and he didn't care about it at the time, one of them accidentally fell to the ground and shattered, but then, something surprised him happened.

Originally, he was in an alley, but when the bottle was broken, a large cloud of green gas came out, condensed around for a long time, and soon after this gas came out, a large number of footsteps rushed in their direction, no need to think that the one who can run so blatantly in the end of the world is a zombie.

Tianchen was frightened at that time, so many zombies, it was not something he could deal with alone, and he was so angry that he almost scolded his mother. However, when he was ready to give it a go and fight to the death, a scene that shocked him happened.

I saw that although all the zombies rushed towards him, they all ignored him, and rushed into the green gas without hesitation.

"Zizi! ~~~”

As soon as the zombie entered the green gas, the sound kept ringing, and as the sound was remembered, the zombie kept roaring, and finally fell to the ground and died unconsciously.

Tianchen didn't know what this thing was, but he knew that when it came to dealing with zombies, this thing had a miraculous effect, even if it died, zombies still couldn't come out of the green gas, which showed that this thing was the nemesis of zombies at all.

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

Of course, it is impossible for him not to show the current situation, because if he does not have his life, everything is empty talk for him.

"Humph! Die for me! ”

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

"Smack!"

The bottle shattered, and a large cloud of green gas instantly spread around it.

"Roar! ~~~”

The gas overflowed, and the first to bear the brunt was of course the nearest second-grade zombie, and when the gas surrounded it, it only listened to the roar from his mouth, and the pain in it could be felt by anyone.

"Roar, roar, roar! ~~~”

It's not just second-grade zombies, when the green liquid overflows, all the zombies around them put down the opponents around them, even if the knife is slashed at them, they also don't care about it, and firmly rush into the green gas.

Bursts of painful roars kept coming, and all the people opened their mouths in surprise to look at the scene in front of them, just now they were on the verge of dying, but now they watched the zombies continue to rush towards the green gas like suicide, and they kept pouring into the green gas, no matter how they looked, there was a weird feeling.

Bai Cen, who was just about to start, also looked at everything in front of him in surprise, and his heart was no less shocked than others.

"What the hell is this, and why do zombies go so desperately to die?"

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

Purifying gas: Virus, a second-level first-grade item, effective for all zombies below level 2, once the gas is released, zombies within a certain range will be attracted, and killed by the purification virus generated in the gas.

"It's actually a second-level item, this Tianchen is really a loser!"

Bai Cen was very angry, the consequences were very serious, second-level items, that was a second-level item, although it was only the lowest grade, but if this was to be exchanged, how many energy points could be exchanged, and how many meals could be eaten.

The more he thought about it, the more angry Bai Cen became, and now he couldn't wait to walk to Tianchen's side immediately, and without saying anything, give him a few big mouths first, so that he could sulk. He had already tried it just now, and using the exchange function was not good for the green purification gas in front of him.

Given that Tianchen was too far away from his position, Bai Cen had no choice but to take out his anger on others, and not far from Bai Cen, there happened to be such a person who could make Bai Cen angry.

Murderer, at this time he can be said to be scarred, although the zombies have all been eliminated, but Bai Cen still decided to do it. To be honest, if it were normal times, let Bai Cen deal with Tianchen and the three of them alone, Bai Cen would definitely hesitate, after all, although the strength of the murderer and the mad doctor is average, it is not the same with Tianchen, who is only slightly inferior to him.

But after all, that is a normal situation, now it is different, the three of them can be said to have suffered a lot of injuries, and their combat effectiveness has plummeted, of course Bai Cen will not let go of such an opportunity, and the murderer closest to him has just become Bai Cen's target.

Now that it has been decided, of course Bai Cen will not hesitate, while everyone else is looking in the direction of Tianchen, Bai Cen slowly approached the murderer's back, and when he was only a few meters away, Bai Cen accelerated, and the dragon pattern knife in his hand stabbed the murderer's heart.

"Poof! ~~~" With a soft sound, the Tang knife in Bai Cen's hand stabbed the murderer without hindrance, but although he was stabbed, the murderer did not die.

It turned out that when Bai Cen was speeding up, he didn't know if the murderer felt something, so he coincidentally glanced back, and happened to see Bai Cen who rushed towards him, although he was stabbed, but at the critical moment, he dodged the fatal wound and only let Bai Cen pierce his arm.

"Ahh ~~~”

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

"Who are you!? What are you doing!? ”

The screams alarmed everyone, and the sudden shock also stunned everyone, but the first to react was the mad doctor, after all, he was the closest to the murderer's position, and when he heard the sound of the dragon knife piercing the murderer's arm, he had already looked in the direction of Bai Cen, so, when the others were stunned, he had already realized something, and rushed towards Bai Cen for the first time, while rushing, he did not forget to distract Bai Cen's attention.

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

Although there was no knife to kill the murderer, but it was harmless to Bai Cen, seeing the mad doctor rushing towards him, Bai Cen crossed the corner of his mouth with a wicked smile, and the dragon pattern knife in his hand was horizontal, taking away one of the murderer's arms, and also facing the mad doctor's iron claws.
