"How are we going to go down?" Qi Zhuang said.

"Take a walk around this hallway." Wang Yuan said. They were on the cliff dozens of meters high at this time, and the two-meter-wide corridor in front of them seemed to be completely carved out of this jagged cliff, and there was no trace of splicing even the stone handrails. The slender corridors have a lampholder-like thing every few meters, which is supposed to have been used for lighting 2,000 years ago. Compared to such a large underground space, the faint blue light here obviously could not meet the needs of the ancients. And in this huge space, the blue light source is basically emanating from the top.

"You say that with this kind of insight, how can the great war of 2,000 years ago be so clearly preserved?" Qi Zhuang said.

"It only means that two thousand years ago it was much brighter than it is now, what is this thing that glows blue?" Wang Yuan said.

"It's supposed to be the bones." Wang Yuan said.

"Anyway, we're going to have to get out of this place first, and once it's made public, it's absolutely another miracle in human history." Zhao Bin said.

"It's a miracle, it's hard to believe how the ancients built these things underground, and where did they get all the quarried stones?" Wang Yuan said. Said.

"Huh? There's a way down ahead. Qi Zhuang saw that the corridor in front of him was divided into two, and a path leading to the bottom appeared, and several people looked down, although the passage was long, it seemed to lead to the vicinity of the city.

"We are not far from the exit, comrades, show your energy!!" Qi Zhuang said excitedly.

A few people suddenly gained momentum, and they didn't care about the physical and mental exhaustion, and walked down, they couldn't remember how many times they had gone down.

"Although I encountered a lot of bad luck after coming in, I seem to be lucky, and even some unlikely things have become so natural, am I suspicious?" Wang Yuan suddenly had a question in his heart when he saw this corridor leading to the giant city. "It seems that what I've been through lately has really made me very anxious."

A few people quickly reached the ground, but in front of them was blocked by a deep ditch, not far away is a huge city wall about ten meters high, although it is old, but there is no wind and sun here, so the city wall seems to be very well preserved. What made Wang Yuan a little strange was that the surface of this city wall was pitch black, and it did not glow blue like the other buildings in the passage before.

"It's supposed to be a moat, but it's dry." Zhao Bin said.

"Did water flow through here before?" Qi Zhuang said.

"Is there really a need to build a moat here?" Wang Yuan said.

This deep ditch was not deep, and a few people quickly walked over, and then walked in and looked at the pitch-black and tall city wall in front of them, and they didn't feel a little creepy.

"Circle it, you'll always look at the gates." Wang Yuan took out the compass again, looked at it, and put it away again.

There were only a few people's footsteps left, and a few people walked quickly, but the city was really amazing, and after walking for more than ten minutes, I still didn't see the so-called city gate.

"If only we walked backwards." Qi Zhuang muttered.

"No, didn't Liu Jia say that there are four city gates? Then we've been walking for more than ten minutes, and we should meet it. Wang Yuan said.

"I was deceived by her again...... Qi Zhuang said.

"Actually, I don't think she's a bad person...... Xiaoying said.

"She almost killed us, and you still say that." Qi Zhuang said.

"I just feel ......," Xiaoying said with a little grievance.

"I remember when she said that there seemed to be four huge gates in the east, west, south and north, and she said that it was very likely that she deduced it." Zhao Bin said.

"What do you mean?" Wang Yuan said.

For example, if you see a huge gate in the south, north and east of a city, then you will naturally conclude that there is one due west." Zhao Bin said.

"That's far-fetched...... Could it be that we can just come across the side without the gates? Qi Zhuang said.

"Look ahead! Is that a door? Wang Yuan pointed ahead.

A few people saw a strange silhouette of a building looming out in the distance ahead, and several people ran towards it. As they got closer, they saw that the moat seemed to lead into the city. And when they arrived, they found that the strange structure protruding from the city wall was actually a huge stone sculpture of a dragon head! The dragon's head was about four or five meters tall and had a large mouth, which seemed to be a little different from the common dragons in New Year's paintings, but it was basically the same. It was through the dragon's mouth that the moat led to the city.

"This should be a door, it's quite big, let's see if there is an exit across from him." Qi Zhuang said excitedly.

"But the opposite side of him is the direction we came from......" Xiaoying said.

"Let's find out first." Wang Yuan said.

Several men had crossed the dry moat to the opposite side, and searched carefully on the opposite side, but found nothing but the steep rock wall.

"Oh my God...... Help us, we're going to die of exhaustion!! Qi Zhuang shouted.

Xiaoying was also so tired that she leaned on a stone and refused to move.

"We went into the city, not from the outside." Wang Yuan said.

"Wouldn't it be too risky?" Zhao Bin said.

"We're going to be tired from walking outside, we don't have that much stamina." Wang Yuan said. In fact, in terms of physical exertion, Wang Yuan should be the worst one.

Wang Yuan...... I see that there seems to be a ...... on the top of the city wall," Xiaoying said, pointing to the city wall.

"What?!" Several people looked towards the city wall at the same time, and sure enough, there was a dark shadow, but it quickly disappeared, and it seemed to have walked down from the city wall.

"What should we do, Wang Yuan." Qi Zhuang said.

"Don't ......move even if you stay here" Wang Yuan didn't pay attention for a while, affected by so many strange things, he wasn't even sure if it was a human or a ghost.

"Children, I've been hungry here for 2,000 years, do you have anything to eat?" At this time, this sentence suddenly came from the dragon's head.

"Damn,!" Qi Zhuang was so frightened that he quickly hid behind the stones.

Wang Yuan also froze for a moment, but reacted quickly, and scolded excitedly: "You old thing, you are not serious, hurry up and save us out!" ”

At this time, a word came from the cave: "You little rabbit cub, how can you talk to your Uncle Liu." "It was none other than Liu Shiye who spoke.

"My dear Uncle Liu......" Several people suddenly burst into tears and ran towards the dragon's mouth as if they were crazy.

Several people saw Liu Xingye hugging him tightly, almost strangled him out of breath, Liu Xingye also seemed to have tears in his eyes, and said: "It's great that you are all fine, it's all Uncle Liu, I shouldn't have brought you here." ”

"Uncle Liu, where's my dad?" Xiaoying didn't care about wiping the tears on her face and asked.

"Your dad slept and was probably hungry." Liu Xingye pointed to a residential-like house next to him and said. Several people saw that Li Fangzheng was sleeping against the wall, and they didn't even hear their shouts just now. Xiaoying saw that Li Fangzheng was fine, so she ran over excitedly and woke him up. Li Fangzheng looked at Xiaoying in front of him and hugged her tightly excitedly, and the father and daughter cried at the same time.

"It's so touching...... Liu said.

"By the way, what about Professor Zhou?" Wang Yuan asked.

"When he came in, he looked around like a monkey with excitement." Liu Industrial said.

Wang Yuan looked around and found that all around him were ordinary ancient dwelling-style bungalows, like a village.

"Uncle Liu, take us out of here, I'm dying of hunger." Qi Zhuang said.

"You losers, didn't I say you should save some food?" Liu Xingye said angrily.

"The food left me next to the hole where Wang Yuan fell in." At this time, Xiaoying and Li Fangzheng also came over.

"Where did you fall? By the way, why are you kid in tatters, Qi Zhuang and Zhao Bin don't seem to be fine. Liu Xingye noticed that the grizzled Wang Yuan and Qi Zhuang Xiaoying formed a stark contrast.

Wang Yuan told Liu Xingye and Li Fangzheng some of the things they experienced from beginning to end, but Liu Shiye and Li Fangzheng stood in place for a long time without speaking.

"Alas...... This journey has almost used up the luck of this life. Wang Yuan said with a sigh.

"That woman named Liu Jia wants to trap you in a hole?" Liu Xingye asked.

"Well, I analyzed that she first used a sensational story to make us let our guard down." Wang Yuan said.

"We've long seen that he's not a good thing." Qi Zhuang said.

"And you said that the scar-faced man ran away after listening to two locust trees?" Liu Xingye asked again.

"Well, we pretended to be the two locust trees, and then he led the gang away, or we might have died there." Wang Yuan said.

Liu Xingye fell into deep thought again......

"Why hasn't Zhou An come back yet?" Li Fangzheng said.

"Uncle Li, did you see the battle at the top just now?" Wang Yuan asked.

"Those sights are incredible...... Li Fangzheng nodded. How did people in ancient times do it? Nothing here is like what a living person can do. ”

"Zhao Bin seems to say that it's called magnetic field photography, which is a natural phenomenon...... Xiaoying said. Li Fangzheng shook his head and said that he couldn't understand.

"I've lived for most of my life, and it's the first time I've watched this kind ......of movie," Liu Xingye said.

"When did you get here?" Wang Yuan asked.

"We've been here for about two hours, and we originally wanted to go out directly, but Zhou An proposed to wait here to see, can we wait until you guys, it just so happens that he is also going to go around the city, so we agreed. Coincidentally, as soon as I got up the wall, I heard the movement of the four of you. Liu Industrial said.

"Uncle Liu, how come you have a city here?" Wang Yuan asked.

"I've been here before, I'll tell you when I get out, now is not the time." Liu Xingye could only confess at this time.

"If it weren't for the delay between us, maybe you wouldn't have been able to wait for us here." Qi Zhuang said.

"Well, don't mention it, our experience is not much better...... If I hadn't wittily discovered the underwater passage, maybe a few of us would still be sitting there and soaking our feet. Liu Xingye said. Did you go to see the strange glowing symbols when you left? ”

"It's a bit uncomfortable to watch for a long time, I don't usually look at it, and the woman named Liu Jia told me that these symbols will make people go crazy if they look at them for a long time." Wang Yuan said. Qi Zhuang said that there were not many symbols of the road they took.

"It's just that Li Fangzheng's stupid hat will be ......evil," Liu Xingye said angrily. Li Fangzheng on the side scratched his head in embarrassment.

"What's going on?" Wang Yuan asked.

Liu Xingye told Wang Yuan and the others about how they jumped from the stone pillar in the underground space......
