Chen Beichen ignored the ordinary zombies in the lobby on the first floor and went straight to the second floor.

The corridor on the second floor is very quiet. After all, it is the offices of various leaders of the school, and most people will not come here even if they have nothing to do.

However, what surprised Chen Beichen was that there was not a single zombie in the corridor, and I don’t know where the zombies went.

Chen Beichen glanced over and found that there was no principal's office and then went up the steps.

Soon, Chen Beichen arrived at the third floor. The third floor and the second floor were the same as those of the school leaders.

After taking a look, Chen Beichen prepared to continue to go up the fourth floor.

"Bang!"

"Bang!"

"Bang!"

...

Just as Chen Beichen was about to continue going upstairs, a sound suddenly came from a room at the end of the corridor on the third floor.

The sound inside was a bit like something was hitting the door, and it was hitting hard!

After Chen Beichen heard the sound, his expression moved slightly, and his hand flipped, and the Youlan Gun appeared directly in his hand.

"Bang!"

At this moment, a louder sound came, and then I saw a zombie breaking through the door.

A big hole appeared in the door, which basically encompasses the entire door, just like removing the door.

Chen Beichen looked around and a male zombie rushed out of the door.

I saw that the zombie was about the size of an ordinary zombie. It was covered in blood and its fangs were terrifying. One of its eyes fell, and a blood hole fell down, which was constantly bleeding out.

The most noticeable thing is that its mouth is very large, its throat seems to be swollen, and there is some green mucus on his body.

At the same time, the sound of a prompter sounded in Chen Beichen's mind.

[Mutative Zombie - Squirt Zombie: A mutant in a zombie, it can spray green venom, you have to be careful of its mouth.]

Hearing the sound of the prompter, Chen Beichen was slightly stunned. Unexpectedly, he could even encounter mutant zombies here.

This kind of zombie Chen Beichen learned in the book "Collection of Crypts" that this is a zombie that can conduct long-range attacks. The green venom it sprays out is extremely terrifyingly corrosive.

Not to mention human beings, even if the titanium alloy touches that green venom, it will be corroded and melted in an instant.

Although Chen Beichen has some cultivation, he dare not use his body to block this venom.

"Shit!"

It seemed that Chen Beichen's existence was sensed. The zombie seemed extremely excited. Her bloody mouth kept squirming, as if something was inside.

Chen Beichen's face changed. Without saying a word, he put away the Youlan gun and took out the Shadow Crossbow.

He doesn't plan to fight with him in hand to deal with such a ranged zombie.

At this moment, as soon as Chen Beichen took out the shadow crossbow, the zombie rushed over.

At this time, the mutant zombie's mouth bulged slightly, which was obviously a sign of venom being sprayed.

It takes a little time to launch the Shadow Crossbow. Obviously, Chen Beichen had no time to use the Shadow Crossbow he just took out.

With a "chi!" sound, the terrifying mutant zombie opened its mouth wide and spit out a dark green venom.

For a moment, the narrow corridor was covered with green venom, which made Chen Beichen unable to avoid it!

Seeing this scene, Chen Beichen's face suddenly changed. He didn't care about using the shadow crossbow. The spiritual energy in his body turned directly, and the water condensation technique wrapped around his body. He ran into the door on the right.

"Bang!"

He knocked open the door and Chen Beichen disappeared into the corridor.

At the same time, this dark green venom sprayed directly at the location where Chen Beichen was before.

"Swish!"

Blue smoke rose up, and huge pits appeared in the corridor, as if you could see the scene on the second floor. Obviously, these floors were penetrated by this dark green venom.

On the other side, Chen Beichen crashed into an office directly.

After coming in, Chen Beichen looked at the office with vigilance in case the zombies in the office attacked him. But what surprised Chen Beichen was that there was no zombie in the office.

Since this place is quite safe, Chen Beichen just glanced and stopped observing.

Without saying a word, he took out the shadow crossbow and looked at the door where he had knocked out a big hole. The spiritual energy in his body quickly gathered towards the shadow crossbow.

"Bang!"

The mutant zombie saw the fat meat flying out when she saw it roaring and rushed directly into the office where Chen Beichen was.

"Swoosh!"

As soon as it came in, it was a long dark arrow.

"boom!"

The mutant zombie had no time to react and was shot through the head by a long arrow.

"Bang!"

With a loud noise, the mutant zombie fell heavily to the ground.

When Chen Beichen saw this scene, he finally breathed a sigh of relief. The venom of this mutant zombie was very unusual, and he felt that his water condensation technique could not stop it.

Fortunately, I used the Shadow Crossbow, but by this, nearly half of the spiritual energy in my body had been gone.

Chen Beichen ignored the consumption of spiritual power in his body, and came directly to the corpse of the mutant zombie.

At this time, his eyes were filled with purple light, trying to find the crystal core of the mutant zombie.

Needless to say, the crystal core of this mutant zombie is not ordinary.

Soon, a dark green crystal core the size of a little finger was found by Chen Beichen from the zombie's body.

[Low-level mutant crystal core: This is the crystal core of a venom zombie, which contains pure poison gas, suitable for those who practice poison skills.]

Hearing the prompt from the prompter, Chen Beichen smiled bitterly and after a long time of work, it turned out to be something useless to him.

Shaking his head slightly, Chen Beichen still put away the low-level mutant crystal core.

[System reminder: Low-order mutant crystal core 1]

After putting away the mutant crystal core, Chen Beichen took out a middle-level spirit stone. He was about to restore his spiritual power while looking for the principal's office.

Soon, Chen Beichen searched the fourth and fifth floors.

Finally, he found the principal's office on the fifth floor, but it was empty inside. Not to mention the golden treasure chest, there were not even zombies.

Obviously, the president of Jiaotong University is not here.

Chen Beichen sighed slightly, and he knew that it would not be so easy to find it.

So Chen Beichen stayed directly in the principal's office, sat on the sofa, and began to silently restore the spiritual power he had consumed before...

...

Time passed quickly for more than ten minutes, and Chen Beichen suddenly opened his eyes, his eyes were full of energy, and he could not see for a long time of fatigue.

Then, he glanced at the spirit stone that had not changed much on the surface of his hand and put it away.

At this time, Chen Beichen had completely recovered the spiritual power in his body.
