Ouyang Qing and the others listened to what Su Peng said, naturally there was nothing to do, although the number of guards on the other side was relatively large, but Su Peng's side had an advantage, that is, Ganluo was on Su Peng's side.

Commander Ganluo is the instructor of the guards of Qiuzi Qiancheng, most of the guards of Qiuzi Qiancheng have learned swordsmanship from him, and his prestige is very high, as long as Ganluo is in charge, even if the other party leads more guards than Su Peng and others, he will not directly conflict with Su Peng and others.

In fact, the real enemies of Su Peng and the others are just some masters of the other party.

"Judging from the current situation, among these True God Sect people and white-clothed people who know magic, there are no particularly hard ideas."

Su Peng thought in his heart, those people didn't seem to have particularly powerful masters, otherwise the last time he entered the desert, he wouldn't have hired an alien master like Ouyang Qing.

In this case, if it is only at this level, even if there are more than ten people on the other side, Su Peng is confident that he can capture or exterminate the other party by relying on his current subordinates.

Therefore, Su Peng was very relieved to let his people walk from the road that President Yang Xi had walked to see if there was anything cheap to pick up.

The man in white just now and the more than forty guards led by the True God Sect were taken in by the commander of Beganluo and received from Su Peng's men.

Su Peng was worried about whether there were fewer people on his side, and it was not easy to deal with any dangers encountered in the underground city, and after joining these forty people, Su Peng's worries were alleviated a lot.

Those guards already knew each other, and there was no problem in commanding, plus they all brought enough water and food, Su Peng didn't need to worry about these, just the extra manpower to help.

Su Peng was very happy to get some manpower replenishment again, so he asked these guards, as avant-garde troops, to take Su Peng and the others to the places they had walked through.

……

Su Peng and the others advanced in this underground oasis for a while, and then saw a dirt slope in front of them. From the dirt slope, there is another tunnel.

And listening to the guards who were originally brought by the True God Sect and the men in white, after passing through the tunnel, it was still a town, and that town was similar to the town that Su Peng and the others had seen, except that the glowing stone was relatively small, and it was just a little darker.

Su Peng listened, and determined some information in his heart, that is, whether it was the Shimmer City that he had just passed by, or the town that the guards brought by the True God Sect said. None of them are at the heart of this underground city.

These small towns should be peripheral settlements, and the real urban core should continue to focus on the center.

Su Peng deduced a possible topographical structure here in his mind, and after deducing the direction in Su Peng's memory, Su Peng found that the structure of this underground city was a bit like the underground research institute of the umbrella organization in the movie called "Resident Evil" that he had seen. That is, an underground fortress called a beehive.

At the top, there is a hexagonal or octagonal figure, with six to eight town clusters, and this underground oasis in front of you. Form an octagonal or hexagonal figure on a flat surface, and then focus towards the center, there should be a larger city in the center, but I don't know if the road will be a three-dimensional city like in the movie. Continue to extend under the jaw.

As for the oasis he passed by just now, Su Peng also guessed that it should be a place like a plantation. Judging by Su Peng's botanical knowledge, those fungi are likely to be edible fungi.

If this is the case, then this underground city is basically self-sufficient, there are ventilation channels, the air is fine, and then there are plant plantations, looking at those people who live in the underground city, it seems that they can still eat the meat of a special monster, if nothing else, that special animal, may exist deeper underground.

Now, the only thing missing is ...... water source.

If a water source can be found, the lifeblood of this underground city will be all found, and the overall structure will be revealed.

The reason why Su Peng estimated that the city here was three-dimensional was because considering that he should be four or five hundred meters underground now, the height of the water source must be lower than the city itself, so the water source should be in a deeper place.

With this in mind, Su Peng led the team forward to look for clues, and soon found the town that the guards were talking about.

That town was about the same size as the town Su Peng had encountered before, but the light was much darker, and in several directions of the town, there were also several tunnels.

One of them is the tunnel in the direction of Su Penglai, which is where the underground oasis is located, the other is the tunnel where Yang Xi and the others came in, and the other two tunnels are leading to the other two places.

Su Peng calculated the direction and angle of his walking in his mind, and judged that one of the tunnels should be in the direction of the core of this underground ancient city.

And this tunnel, listening to those guards, is also the direction that Yang Xi and the others entered.

Since this was the case, Su Peng and the others did not hesitate, and walked along this tunnel.

Su Peng and the others walked along the tunnel, and after walking for a while, Ouyang Qing suddenly stopped, grabbed Su Peng, and said, "Brother Su, did you hear any sound in front of you?" ”

"Huh?"

Su Peng listened and stopped, he didn't keep his internal strength on his ears just now, but Ouyang Qing kept it in this state.

Su Peng's luck was in his ears, and sure enough, a slight voice came.

After listening quietly for a while, Su Peng frowned slightly, and said, "It sounds, it seems to be the sound of some kind of organ operating?" There are also some footstep sounds, but they don't sound like human footsteps, and the amplitude, distance, and time of each step are too similar. ”

"Huh? Really? ”

Ouyang Qing listened, and was also slightly stunned, his internal strength is his weakness, his sword skills come from the inheritance of the rivers and lakes, it's okay to say, it's just that Ouyang Qing visited famous families everywhere when he was young, but because of his bad background, he touched nails everywhere, on the one hand, his personality became extreme and hostile to famous schools, and on the other hand, his internal skills were not very good.

At this time, the gap in internal force was revealed, he just kept working on his ears, and heard some abnormal sounds, but he didn't hear it as clear as Su Peng.

"There must be some mechanism in front of me that has been activated, I sound like there are hundreds of moving things, but it doesn't look like a person, it doesn't look like an animal or a dark green walking corpse I encountered before, I don't know what it is, but other than that, there are bigger mechanisms activated."

Su Peng said to Ouyang Qing.

Ouyang Qing nodded and said, "Shall we continue to move forward?" ”

"Keep walking, if there is really any danger, then President Yang Xi has also paved the way for us, since we haven't seen their people flee back, it means that we can continue to move forward, let's go and see, what is ahead."

Su Peng was determined and said to Ouyang Qing.

Since Su Peng said so, Ouyang Qing Adulla and the others naturally had no objection, but they asked their guards to be more careful and move forward together.

Su Peng and the others advanced so quickly for a while, and within a few minutes, they came to the core position here.

Sure enough, as Su Peng expected, in the core of this tunnel, there is still a city.

This city is much larger than the two peripheral cities encountered before, and in terms of floor space, it is about four or five times that of the two outer cities.

It's just that there are no people in this city, and in the center of the town, there is an inner city, which is about the size of an ordinary town outside, that is, in the inner city, there is constantly a sound like a mechanical factory that Su Peng has seen in the real world, and there are some sounds of something walking.

"That's it!"

Su Peng stood on the periphery of the core city, looked around, and said to the people around him.

Ouyang Qing stood beside Su Peng, looked around, and said: "I have a good sense of direction, there are more than twelve tunnels around this city, and I judge now that it should lead to the surrounding peripheral cities, whether it is from the city we first encountered or the direction we came from, we can actually enter here." ”

Su Peng nodded and said, "It's really a lot of money here...... Even the caves are naturally formed, but when counted, the core city and the peripheral cities combined are enough for two or three hundred thousand people to live, and it seems that the people who built this city back then were afraid that they wanted all the people on the ground to move here. ”

"yes...... But thinking about it this way, what is the purpose of them relocating so many people underground? And where have all those people gone now? ”

Adullah was beside him, listening to the two of them, and couldn't help but express their doubts.

Ouyang Qing and the rest of the people listened, and their faces also showed a thoughtful look, they hadn't thought about this problem, it took time and effort to build such a huge city, I am afraid that it will not be possible to build a city in fifty or sixty years, and the manpower and material resources spent do not know how much it takes, if this is really the ancient city of the Forest Prison, then the Qingjiao clan who built him will live well in the oasis on the ground, why should he go underground? And thousands of years have passed, where have those people gone?

After being silent for a long time, Su Peng broke the silence at this time and said: "Let's not speculate by ourselves, the city inside now should be the core of the city, there should be some classic records, let's go to the inner city to explore, maybe find some clues, there are many strange people in the world, maybe there are people who understand the words here, they can crack it." ”

After listening to Su Peng's words, Adullah and the others stopped thinking nonsense, and nodded in agreement with Su Peng's statement.

Seeing that everyone had already retracted their thoughts, Su Peng nodded, and he led his team into this core city, heading in the direction of the inner city that kept making strange noises...... (To be continued......)
