End of the world: The school girl turned into a zombie and confessed to me?

In the face of absolute strength, Zuo Nan could only choose to bow his head.

For Zuo Nan's small actions, Zhang Chen saw all of them, but he didn't expose them.

After another ten minutes, Zhang Chen and others finally arrived at the central laboratory.

All the security systems here have been dismantled by Xu Ruina.

The door of the experiment center is open, and one can walk in and out at will.

Zhang Chen took out the walkie-talkie and was about to speak, but there were bursts of noisy voices from the walkie-talkie.

It seems that the entire experimental center has some kind of signal shielding.

"Zuo Nan, contact Shirley and ask where they are!"

Zhang Chen said to Zuo Nan.

Because his ring is turquoise, the system he has is not compatible with the system of the dark red ring.

So Zhang Chen couldn't talk to Xueli directly through the chat channel, but Zuo Nan and Xueli were reincarnated in the same class, so they could chat directly in private.

"Okay, boss, I'll get in touch right away!"

Zuo Nan smiled flatly, and soon, his expression fell into a dull state.

It seems that no matter which class of reincarnations they are in, as long as they use the operation interface, they always have the same dumb expression.

After a while, Zuo Nan frowned and came back to his senses.

"How about it, did you get in touch?"

Zhang Chen asked.

"I did contact Shirley, but she didn't get back to me."

"I asked several questions, and I also said that you were looking for her, but she still didn't respond!"

"Do you think Shirley and the others are in trouble?"

Zuo Nan asked.

"Trouble? Is there any hidden danger in this laboratory?"

Zhang Chen stared at the laboratory for a while.

Soon, a set of prompts appeared next to the laboratory:

[Progressive core laboratory, which contains experimental records and data of the progressive ultimate weapon]

[There are no mutated creatures or infected bodies in this building, but there are some unstable space gaps, please be careful! 】

"Unstable space rift?"

"Is this related to Shirley's loss of contact?"

An ominous premonition suddenly rose in Zhang Chen's heart.

There is definitely a big problem in this lab!

Zhang Chen immediately inserted a teleportation beacon in the hidden alley opposite the laboratory building, and carried the other on his body, leading everyone into the laboratory building

At the same time, beyond the high wall.

The time for the attack arrived an hour after the appointment.

Yan Gang stood up from the chair, straightened his back, then privately chatted with the investigation team, and asked:

"Is there any change in Zhang Chen's side?"

The investigation team: "There is no change at present!"

Yan Gang: "Did Zhang Chen ever leave your sight, and how long has he been away?"

The investigation team: "Zhang Chen has never left our investigation sight. For an hour, he has been sitting on a chair by the window drinking tea, and he hasn't even gone to the toilet!"

Yan Gang was startled, and asked in a sour tone:

"I drank tea for an hour and didn't go to the toilet once? Are you in such good health?"

The investigation team: "Zhang Chen has started to act. He and a group of people around him are preparing to leave the manor!"

Hearing this report, Yan Gang was shocked and said with a smile:

"It's finally time for us to perform well! I hope Wang Zihao's judgment is correct!"

The black-tailed swallow army and the black market merchants gathered at the agreed place.

At this time, I saw Zhang Chen riding the majestic Erpang, and appeared in the field of vision with a group of beauties.

"Huo, this energy beast is so beautiful, this kid seems to be lucky!"

"No wonder Wang Zihao is so confident in breaking the city wall!"

Yan Gang secretly praised in his heart.

When Wang Zihao saw Zhang Chen, he greeted Zhang Chen from a distance:

"Mr. Zhang, I'll trouble you later, we each perform our duties!"

Zhang Chen, who was riding on Er Fatty's back, didn't react at all, looking arrogant.

But Wang Zihao and Yan Gang didn't care.

In their view, Zhang Chen ignored him entirely because he was assigned an insignificant job despite his strength.

It's normal to be angry and ignore people.

The more this is the case, the more it means that Zhang Chen has fallen into the trap.

After a while Mou had enough strength to rush into the city by himself, and the urge to slap Prince Hao Yan Gang in the face would become stronger.

Then the plan of these two people will be more likely to succeed.

Thinking of this, Wang Zihao and Yan Gang smiled at each other, and the performance began!

Chapter 426 Mutation in the High Wall

Outside the high wall, the Black-tailed Swallow Legion launched an attack on the high wall vigorously, and it took a long time before they finally tore a small gap in the energy grid protecting the high wall.

As the energy grid was damaged, countless infected people emerged from the soil and attacked the survivors.

The black market merchants and the Black-tailed Swallow Legion fought hard to resist.

Although the level of infected people under the city wall is not high, there are a large number of them, and they are pouring out from all directions, making it hard to guard against.

Moreover, most of the first batch of awakened black market merchants and members of the Black-tailed Swallow Legion were not that powerful.

So it feels a bit careless to resist.

Yan Gang frowned and looked at the battle situation in front of him, and said to Wang Zihao:

"These infected people are too annoying. If they come out in one breath, I will send strong people to kill them directly!"

"The trouble is that they pop up little by little. If you send strong guards, you will be dragged and unable to leave. If you send weaker players, it's easy to be unable to guard them. It's a headache."

"I don't know when Zhang Chen will do it?!"

Wang Zihao subconsciously glanced in Zhang Chen's direction.

I saw Zhang Chen sitting on Er Fatty's back expressionlessly, looking straight ahead.

I can't see what is going on in his heart at all!

"This Zhang Chen is not easy to deal with. He has a deep scheming mind. Even I can't see any thoughts from his face."

"However, what is certain is that Zhang Chen is definitely more anxious than we are to enter the high-walled city, so he will definitely make a move!"

"Let's wait and see what happens!"

Yan Gang nodded helplessly.

As time passed, the siege team began to blast the city wall!

However, for such a strong city wall, blasting attacks are almost useless, even energy attacks can only create a white mark on the rock.

According to this progress, it is considered fast to be able to break through the high wall in 12 days.

The survivors repelled the waves of the infected, but two or three were seriously infected and joined the ranks of the infected.

At this moment, the sound of a rocket ejector came.

Two teams of enhanced armed mechs descended from the sky!

"The armed mechs are here, you can fight a little slower, I guess Zhang Chen should take advantage of this time to enter the city!"

Wang Zihao narrowed his eyes and analyzed.

"Okay, then I'll trust you again, I hope your judgment is correct!"

With a big wave of Yan Gang's hand, several strong men rushed up to meet the armed mechs.

After a while, the sound of explosions rang out one after another on the high wall.

The huge sound spread around the city wall to the distance, and there were waves of echoes.

"Ow~!"

"Clack cluck!~"

"Woooooo~"

As the sound of the explosion spread farther and farther, a wave of corpses suddenly rushed out from the shelter of the city wall!

"Corpse tide, why is there a corpse tide?!"

Yan Gang was caught off guard by the tide of corpses, so he had no choice but to go into battle himself and lead his team to resist.

"Hiss, this situation doesn't seem right!"

Wang Zihao frowned.

He realized that there must be a problem with the high wall, but for a while he couldn't tell where the problem was.

He looked at Zhang Chen, then at the surging tide of corpses

Suddenly, he had a flash of inspiration and said in surprise:

"Could it be that Zhang Chen has already entered the high-walled city?!"

What?Zhang Chen has already entered the city with high walls?In the distance, Yan Gang was holding a huge axe, and suddenly a wave of energy knocked the surrounding infected bodies to the ground, and then looked at Zhang Chen, who was not far away in surprise, who was riding the fat Zhang Chen leisurely.

"If Zhang Chen entered the high-walled city, who is this person?"

Wang Zihao jumped to Yan Gang's side and tapped his right hand a few times.

Several infected bodies exploded and died immediately before they rushed to the front.

Wang Zihao said:

"If my predictions are correct, the Zhang Chen in front of me is a blindfold. Although the ability to change forms is extremely rare, Zhang Chen obviously has such a means to let others pretend to be himself. In fact, the real Zhang Chen has already entered the city. !"

Yan Gang asked with an expression of disbelief:

"Zhang Chen has already entered the city? Then when did he enter the city?"

"Why didn't we hear anything?"

Before he finished speaking, there was another explosion in the air.

This is the sound of the strong fighting with the reinforced armed mech squad.

The ground was even more noisy, the shouts of the survivors, and the wailing of the infected, one after another.

Such a loud noise can be heard clearly even several kilometers away.

"I don't know what method Zhang Chen used, but this is exactly what makes him extraordinary, isn't it?"

"The tide of corpses was automatically activated by Zhang Chen when he attacked the city wall, but I don't know what method he used to isolate these monsters and keep them quiet."

"As for strengthening the armed mecha, it might be killed in an instant!"

Wang Zihao's voice just fell.

A rocket slammed into the ground next to it.

The huge impact knocked the two survivors to the ground, leaving a large hole in the ground.

"You mean that Zhang Chen, facing such a strong enemy, and there may be ten armed mechas, can kill them without making a sound at all?!"
