The moment the underground passage was sealed, all four of them felt a violent vibration above their heads. The vibration spread to their feet. The display screen hanging on the wall in front of the table was shaking constantly, and two display screens were shaking and about to fall.

Xiao Yang pointed to the ground with his toes, quickly connected the two falling display screens with both hands, and carefully placed them on the ground without letting them make any sound.

The four could clearly hear the low roars above the heads, and the low roars were exactly what the cats were making before hunting.

A huge pressure filled the heads of the four people. Xiao Yang and Zhao Ji felt fine, but Zhao Ning and Quan Dingding both felt a little uncomfortable with chest tightness. It was affected by this pressure. Compared with Xiao Yang and the others, Quan Dingding and Zhao Ning were still slightly worse.

However, even if his strength is slightly worse, Zhao Ning can still use Yuanling City as the basis to kill the people who can kill the sky. His own strength is also in the early stage of the sky.

Quan Dingding has never shown all his strength, but with his talent, he is definitely at the level of seeing the sky.

The pressure alone made them feel tighter, which shows how strong this monster is.

Moreover, the most important thing is that I don’t know how many monsters there are. If they live in groups, even if Xiao Yang goes out, he will give rice.

From that diary, I learned that not only this city, but also the main city recorded in the diary, the Lingcheng City was also breached. Although Lingcheng finally reacted, even the main city was impacted, and the rest of the cities were probably the same!

And among the messages received from the surveillance screen, the strength of this monster should not be the most terrifying one. The neurotoxins that can affect and control people are the most difficult to deal with.

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

The pressure above lasted for a long time. After more than half an hour, the monster let out an unwilling roar and then left. The monster's departure made the ground shake several times.

Seeing the monster leave, Zhao Ning breathed a sigh of relief. As soon as she started to speak, Xiao Yang pointed to the ground and rushed to Zhao Ning at a rapid speed, covering Zhao Ning's mouth.

Zhao Ning's eyes widened.

Xiao Yang immediately stretched out his other hand and pointed to the surveillance screen.

Just saw that in the screen, the monster's figure did not leave too far, but stayed on the street next to it, and the monster's eyes were always on the ground above Xiao Yang and the others' heads.

This monster has not left yet, it is hiding! The monster has extremely high wisdom!

If the monsters don’t leave, Xiao Yang and the others don’t even dare to let out a breath of excitement. After all, there are unknowns everywhere. If a group of monsters is created, everyone will finish playing!

This monster is very patient and stayed here for an hour before leaving unwillingly.

During this period, Xiao Yang and his men also completely saw the monster. The monster was fat. On the fat body, they stared at a huge head, a big mouth could reach the back of the ear, and their sharp fangs were all over the mouth. On the fangs, some broken limbs could be seen.

Zhao Ning breathed a sigh of relief when the monster left this time.

"Put the action, it will come back."

Xiao Yang whispered to Zhao Ning.

Zhao Ning was obviously shocked, and she couldn't believe it.

But soon, Xiao Yang's words were confirmed, and the monster appeared again less than ten minutes after leaving.

Zhao Ning was so scared that the monster's scheming level.

The monster searched three times but failed, and finally gave up. The figure passed through each surveillance camera and disappeared into the monitor.

Xiao Yang searched in this basement. An ordinary person was hiding here, staring at the monitor, watching what happened in the city, which was definitely not just boring. Moreover, looking at these surveillance areas, it was obvious that they were ready for a long time. What was this person doing? And what was the origin of the monster?

The civilization time of this world is definitely greater than that of the ancestors. It is impossible for the world itself to have such a potential crisis.

After searching, I finally found a notebook in the pocket of the corpse.

"The drug works, and it's time to witness the results, hahaha."

"Sure enough, this toxin can control nerves, but the requirements for the controller are too high. If this disadvantage can be improved, then this toxin will be able to dominate the world!"

"A new variant has appeared, it's wonderful, so exciting!"

Xiao Yang looked at this man's notes and could clearly understand from the above that this toxin was created artificially, and that monster was also one of the experimental subjects!

There are always a group of madmen in the world who do everything that ordinary people would never think about!

Xiao Yang smashed the notes in his hand and glanced at the corpse leaning on the chair. From the man's record, he could see that he was ecstatic inside, but he could also learn from his starving death here that the current situation may have exceeded their control.

A city was completely destroyed by monsters, and just because the stench of the corpse was spread, it attracted the monsters more than ten kilometers away. It is not difficult to explain that there were no corpses on the street.

"Boss, let's not stay here. Whether this city is destroyed or not has nothing to do with us. I always feel very gloomy." Quan Dingding shrank his neck and came to Xiao Yang.

"I'm afraid, we can't leave." Zhao Ji pondered, "Look."

On the monitor, dense figures crawled out from different places, all of which were humans!

Green light appeared in these figures, their movements were strange, like zombies in the movie, and the direction they surrounded after these figures came out was where Xiao Yang and the others were.

The monster did not give up. After returning, he summoned his younger brother and planned to do a carpet-style search.

"Damn, this monster is crazy!" Quan Dingding widened his eyes. He didn't even say Amitabha, "Just smell some smell, so what?"

Xiao Yang pondered for a while, "If it was just for the sake of eating rotten corpses, it wouldn't be like this. After all, it controlled so many people, and if such a little movement was worth it, it means that there is something he is looking for in this city!"

As soon as Xiao Yang finished speaking, Zhao Ji was already searching the entire room.

This room is very small. In addition to this monitoring room, there is also a bathroom. A small single folding bed is placed in the corner. Everything is in sight. There is nothing to hide here.

A wave of rustling sounds had already come from above Xiao Yang and his team, which proved that those who were controlled by neurotoxins had arrived here. The dense crowds of people, even if they had the probability of collision, could find this secret room.
Chapter completed!
