At the moment when the underground passage was sealed, all four felt a violent vibration coming from the top of their heads. The vibration spread to their feet. The display screen hanging on the wall in front of the desk was shaking, and two of them were about to fall.

Zhang Xuan pointed his toes to the ground, quickly connected the two falling displays with his hands, and carefully put them on the ground without making any sound.

Four people can hear clearly, in the overhead, spreads the silk silk low roar. As like as two peas before animal hunting, the low growl is like a cat.

Zhang Xuan and Zhao Ji feel good, but Zhao Yong and Quan Ding are two people. Both of them feel a little chest tightness because of the influence of this pressure. Compared with Zhang Xuan and the two of them, the strength of Quan Ding and Zhao Ning is still a little worse.

However, even if his strength is a little poor, Zhao Ni is a man who can see the sky on the basis of Yuanling city. His own strength is also in the early days of seeing the sky.

And Quan Ding Ding has never shown all his strength. But with his talent, he is definitely at the highest level.

It's just the coercion that makes them feel depressed. We can see how powerful the monster is.

Moreover, most importantly, I don't know how many monsters there are. If they live in groups, even if Zhang Xuan goes out, he will send rice.

From that diary, we know that not only this city, but also the main city recorded in the diary, the Mausoleum City, has been conquered. Although the Mausoleum City finally reacted, even the main city has been impacted, and I'm afraid the rest of the cities are also like this!

And among the messages received from the surveillance screen, the strength of this monster should not be the most terrible. The neurotoxin that can influence and control people is the most difficult to deal with.

In the monitoring room, four people didn't say a word.

The pressure on the top lasted for a long time. After more than half an hour, the monster let out an unwilling roar and left. The monster's leaving makes the ground vibrate for several times.

Seeing the monster leave, Zhao Ning breathes a sigh of relief. As soon as he begins to speak, Zhang Xuan points his toes and rushes to Zhao Ning quickly, covering Zhao Ning's mouth.

Zhao Ni's eyes widened.

Zhang Xuan immediately stretched out another hand and pointed to the monitoring screen.

See, in that screen, the figure of the monster did not leave too far, but stay in the side of the street, and the monster's eyes. It was always on the ground above Zhang Xuan's head.

This monster has not gone, it is dormant! Monsters have great wisdom!

If the monsters don't leave, Zhang Xuan, they don't even dare to take a breath out of the atmosphere. After all, there are so many unknowns everywhere. If they make a group of monsters, everyone will be finished!

The monster is very patient. He stayed here for an hour before he left.

And in this period, Zhang Xuan several people also thoroughly see this monster, this monster body fat, in that fat body, staring at a huge head. A big mouth can be grinned to the back of the ear, full of sharp tusks. On the tusks, you can see some debris.

Zhao Ning was relieved that the monster left this time.

"Move gently, it will come back."

Zhang Xuan opens his mouth to Zhao Ni in a low voice.

Zhao Ning was obviously surprised. She couldn't believe it.

But soon, Zhang Xuan's words were confirmed. Less than ten minutes after the monster left, it reappeared.

This monster's scheming makes Zhao Ni feel scared.

After three unsuccessful attempts, the monster finally gave up and passed through the monitors, then disappeared into the monitors.

Zhang Xuan searches in the basement. An ordinary person hides here, stares at the monitor, and looks at what's going on in the whole city. It's definitely not just boring. Moreover, looking at these monitored areas, it's obvious that they are all ready. What on earth is this man doing? And what's the origin of that monster?

The civilization time of this world is definitely longer than that of its forefathers. There can be no such potential crisis in the world itself.

After a search, finally in the pocket of the body. Find a notebook.

"The medicine is effective. It's time to witness the results. Ha ha ha."

"Sure enough, this toxin can control nerves. It's just that the requirements for controllers are too high. If we can improve this drawback, then this toxin will rule the world! "

"There's a new variant, wonderful, wonderful!"

Looking at the man's notes, Zhang Xuan can clearly understand that this toxin is man-made, and the monster is also one of the experimental subjects!

There is always a group of lunatics in the world, doing all the things that ordinary people will not think about!

Zhang Xuan smashed the notes in his hand and looked at the corpse leaning on the chair. From this man's records, we can see that his heart was ecstatic, but we can also understand the current situation from his starvation here. I'm afraid it's beyond their control.

A city is completely occupied by monsters. Just because the stench of corpses spreads a little, it will attract monsters more than ten kilometers away. It is not difficult to explain that there are no corpses in the street.

"Boss, let's not stay here. It doesn't matter whether the city is destroyed or not. I always think it's very gloomy." All Ding Ding shrinks his neck and comes to Zhang Xuan.

"I'm afraid. We can't go. " Zhao Ji pondered, "you see."

On the monitor, dense figures, crawling out from different places, are all human beings!

These figures, with green light in their eyes, act strangely, just like zombies in movies, and the direction of these figures after they come out is exactly where Zhang Xuan and them are.

The monster didn't give up. After going back, he called his younger brother and planned to do a carpet search.

"Lying trough, this monster is crazy!" All Ding Ding stare big eyes, he even Amitabha did not say, "just smell some smell, as for?"

Zhang Xuan pondered, "if it's just for the sake of eating rotten corpses, it won't be like this. After all, it controls so many people, and it's worth it to have such a little movement. That means that this city has something he's looking for!"

As soon as Zhang Xuan's voice fell, Zhao Ji had searched the whole room.

The room is very small. In addition to the monitoring room, there is also a bathroom. A small single folding bed is placed in the corner. You can have a panoramic view of everything. There is nothing to hide in it.

The sound of rustling came from Zhang Xuan's head, which proved that those who were controlled by neurotoxin had come here. The dense crowd, even the probability of collision, could find the secret room.

For Zhang Xuan, it's almost impossible for them to leave the same way now.
