"Zhang Xiaohu, I finally found you?" Xu Haitao's voice suddenly sounded in the tunnel, startling Zhang Xiaohu, and he turned around to see that it was not only Xu Haitao, but Song Haoze also followed. Both of them looked anxious.

Zhang Xiaohu couldn't help but ask, "Why are you all here?" ”

"You also said that your rope was broken, and we thought we couldn't find you! But it's okay! OK! Xu Haitao patted his chest and said, looking frightened.

"The terrain is so complicated, you can find it so quickly?" Zhang Xiaohu felt a little incredible. It was only a few minutes since he found out that the rope was broken, and Xu Haitao and the others were able to rush here so quickly.

"We followed the rope to find it!" Xu Haitao explained: "Fortunately, your rope didn't move on the ground, otherwise how would we find you here!" ”

"What do you think this is?" Zhang Xiaohu took out the golden sheet from the backpack and showed it to everyone.

"O my God! How... How did I have another box! Xu Haitao's mood was completely confused, and he was surprised that he couldn't say a complete sentence.

"I can't explain it, it's weird everywhere!" Zhang Xiaohu said helplessly.

"Don't worry about this, with these treasures, let's ......" Xu Haitao was about to continue excitedly, but Zhang Xiaohu covered his mouth and warned: "Old Xu, don't talk nonsense!" Zhang Xiaohu still remembered that in the previous time, they had just expressed the use of the golden flakes to carry out follow-up tasks, and the golden flakes disappeared immediately, and he didn't want to have a similar thing happen again.

Xu Haitao sensed Zhang Xiaohu's intentions, and hurriedly covered his mouth and nodded his head twice.

"Let's go back to King Peter and them, and then find an exit out of here!" Zhang Xiaohu said.

Xu Haitao and Song Haoze responded casually, and the three of them turned around and walked backwards.

They walked no more than a dozen meters. Song Haoze suddenly squatted on the ground and let out a sigh: "Huh? ”

"What's wrong?" Zhang Xiaohu immediately asked.

"Here's the signal I left behind, I remember here, go to the right from here, and you'll soon see the entrance where we enter!" Song Haoze said excitedly.

"Haha, that's great!" Xu Haitao clapped his hands and laughed: "You can leave this ghost place, we have been delayed here for too long!" ”

"What is this called delay, without this opportunity, how can we get some good treasures!" Song Haoze also laughed.

The important golden flakes were lost, and they had found their way out, and the two of them were of course happy. Only Zhang Xiaohu didn't feel the slightest sense of joy, he always felt that what happened here was too strange. He still remembered the fear he felt when the hand of unknown origin touched his shoulder. However, he didn't plan to talk to Xu Haitao about these things, and when he heard this matter in other people's ears, he would only think that he was hallucinating.

The next thing went a lot better, and when they returned to King Peter, Peng Jiadong also woke up, although his spirit was still a little sluggish, but he finally returned to normal. According to the mark left by Song Haoze, they returned to the surface smoothly along the passage they came.

At this time, the sun was setting in the west, and it was about to enter the night in another hour, and they were delayed in the pit below for another half a day.

In this dangerous world, sleeping in the wild at night is very dangerous, especially when they cannot live.

But none of the five of them wanted to go back to the tunnel below, and after coming into contact with the light, none of them wanted to go back to the darkness. Humanity is such a race that pursues light.

Zhang Xiaohu and the others finally bypassed the canyon and mountain range, and a flat terrain appeared in front of them again.

However, what frightened and shocked them was that there was no trace of nature on the land in front of them, but a super-large city towering. The cluttered roads and buildings of different shapes are densely packed all the way to the horizon.

"What's this singing?" Xu Haitao touched his head, looking incredulous.

"We're not going to travel through the city, are we?" Song Haoze said in horror.

"It's... Is this simply impossible? "King Peter sat down on the ground, and he had just seen a swarm of ships rise from the sky above the city, densely packed like a swarm of bees.

"Captain, why didn't anyone tell us about the situation here?" Peng Jiadong also felt a deep sense of powerlessness. There must have been millions of inhabitants living in the huge and incomparable city in front of them, and the five of them alone would not have been able to travel through the past.

Zhang Xiaohu had a ridiculous feeling in his heart, and this trip could already be declared a failure by this point. However, he believed that Xiji did not know the actual situation here, otherwise, she would not let herself and others carry out this infiltration mission with no possibility of success.

What is the purpose of No. 4 to establish such a huge city here? Could it be that the residents of this city are all cyborgs, Zhang Xiaohu feels extremely terrifying when he thinks about it.

The five of them were in a fairly secluded position now, with some tall trees to shelter them. Seeing that night was falling, they decided to find a low place and discuss the next steps.

Several people knew in their hearts that this operation had been terminated, and they only needed to return the same way, find a place where no one was around, and then summon the warriors of the Legion of Victims and use the flying machine to leave here. As long as you pay attention to concealment, so that No. 4 does not find out his whereabouts, you can leave safely. As for the other infiltration missions, they simply cannot be carried out.

Xu Haitao deduced that the general experimental center of No. 4 had a high probability of being set up in a certain location in the city. Even if they do, what can they do there?

Song Haoze held a short knife in his hand and pierced small holes in the ground.

Xu Haitao rubbed his spear blankly.

King Peter was lying on the sleeping blanket, his eyes fixed on the canopy above his head, and he didn't know what he was thinking.

Peng Jiadong leaned on the trunk of a big tree, his hands around his chest, his eyes closed and silent.

Zhang Xiaohu, on the other hand, stood on a thick branch, looking at the city lights in the distance, and all kinds of lights shining in the city.

The city is really prosperous, which makes Zhang Xiaohu hard to believe that in such a strange world, he will see such a shocking civilized city. And it was also built by the weirdest number 4 among engineers.

In his mind, No. 4 has always been a ruthless, treacherous, perverted and terrible person, shouldn't such a person hide in the steep mountains, that is in line with his character. How could there be a scene in front of you? What the hell is this person thinking? I really can't understand it anymore!

"I see!" Suddenly, King Peter roared.

Zhang Xiaohu was almost frightened by this shout and fell under the tree.

The other people around him also showed surprised expressions, but they all stared at King Peter as he sat up.

"Mr. Wang, what's wrong with you?" Peng Jiadong asked.

"I know what's going on in this city?" King Peter said excitedly.

"Ahem! I thought you were going to say something! Xu Haitao sighed: "We have long understood what is going on in this city!" Isn't that the person who built it? ”

"Yes and no!" King Peter explained.

When Zhang Xiaohu heard this, he immediately jumped up from the tree and asked urgently, "Tell me about it!" ”

King Peter looked at the eager eyes of several people around him, coughed lightly, and said, "If I guessed correctly, the city in front of us is actually the General Experimental Center of No. 4. The purpose of the city he built here was to observe the changes of individual life through ubiquitous surveillance, and to collect parameters for his experiments. To put it simply, this kind of city is a large culture vessel, a large experimental field, and the creatures in it are like guinea pigs for experiments! So, you all get the idea! ”

Peng Jiadong raised his hand and said, "I don't understand, what does doing experiments have to do with mice, mice are indeed rare if they are white!" ”

Zhang Xiaohu explained with a wry smile: "Uncle Peng, if you don't understand, we can all understand, and we can't explain this matter in a word, so I'll have the opportunity to explain it to you again in the future." I think there is some truth to what King Peter said! This would explain why such a city suddenly appeared here! ”

"Classmate Zhang Xiaohu, but even if this is the general experimental center, we can't get close, we people are unfamiliar faces at first glance, I'm afraid that we have been caught before we go to the city!" Xu Haitao said.

"No!" King Peter denied: "For a city to be maintained, there must be contact with the outside world, and we just need to observe the neighborhood to see if there are any people or chariots and horses from the city, and then we will have a chance to blend in." In such a city dominated by observation, although there is surveillance everywhere, his order must not be too perfect, and the constraints on residents must be very relaxed, only in this way can we more effectively observe the light or dark behavior of living creatures! ”

Zhang Xiaohu stared at King Peter for a while, as if he knew this person again, and said with emotion: "Old Peter, I really don't know, if it weren't for your order, we people would have thought of this." Thank you so much! ”

"Hey, what are you talking about, kid!" King Peter laughed and said, "I also suddenly thought of this. I remember when I was in school, my professor asked us to observe the insect society, and this is how we built an anthill that is extremely large for ants. In order to observe the behavior of the ant colony, we set up a lot of artificial interference and collected a lot of information quickly and effectively! I immediately thought of the situation we are encountering! ”

In this case, let's take a good rest, and starting tomorrow, we will wait for the opportunity to enter the city nearby! Zhang Xiaohu said.
