I walked to the bridge head. There was no unnecessary decoration and carving. I thought it was built purely for crossing the river, or in other words, the people who built it only made it a simple tool for crossing the river.

So why do the people who built the bridge cross the river? What do they do there?

No wonder the five sisters are curious, and I am also very curious, but I can't keep up. I have been down for a while. Chen Qinghan will be worried that something happened to me if he doesn't go back.

I drilled back into the hole, turned back to the maintenance passage, and told Chen Qinghan and Jerry that there was an underground river below, and there was an ancient bridge that was immortal for thousands of years and never collapsed.

When Jerry heard my description, he immediately became interested and said that it would be great if he could go down and take a look.

He just looked like he was going crazy if he didn't go out. Now he heard that there was a thousand-year-old bridge below, and his eyes immediately shining.

"No matter where it leads, it is definitely not an exit." Chen Qinghan frowned gently and pondered, "Maybe it was an underground fortification built by another wave of people."

"But chicken, then maybe you can hide below. Otherwise, you can wait for me for a while and I will go and see it, and come back after watching it." In this underground world, I feel more comfortable than being outside. It would be a pity not to watch it if there is fun.

"Okay, be careful." Chen Qinghan nodded simply.

"No, you can't go. The monster went, and those fierce women went, so did it. There will be dangers when you go." Jerry opposed.

"Well... I won't let them find out, they will hide well." I swallowed the words to my mouth and changed to a gentler speech.

Jerry was a little excited, so I don’t give him a blow anymore. If I tell him that I would be safe without him, it would probably be a big blow.

Chen Qinghan also said, "She is very professional. She walked to the main tomb square alone, and it was unscathed."

Only then did Jerry realize that things happened before. He might not have had time to think too much.

Now that Chen Qinghan reminded him, he stared at me for two seconds, his mouth half open, as if he was about to say something. After his throat moved, he closed his mouth and made a "please" gesture towards the hole.

Chen Qinghan gave me a whistle. The material of this whistle was not metal, but should be the bones of some kind of creature.

"If you blow this below, if the distance is not particularly far, I can hear it. Blowing a sound means everything is fine, two sounds means you can't get up for the time being, three sounds means there is danger, let's leave soon."

I took the whistle, put the rope around my neck, and nodded to indicate that I remembered it.

"Wait, if there is danger in her, how can we go down to save her?" Jerry heard Chen Qinghan's instructions and noticed that there was a loophole, so he quickly asked.

"We can't get down, and there is no time." Chen Qinghan said very objectively.

Although Jerry wanted to refute, he had nothing to say because what Chen Qinghan said was the truth.

He couldn't think of a solution, so he could only shut up. In this underground world, it was useless to care only, and he also needed the ability to solve all difficulties.

Jerry obviously does not have such strength, so he has no other way except kicking the stone and venting his anger.

I returned to the cave and climbed to the underground riverside. The bridge was quiet and the river water flowed quietly, and there was no other sound around.

I grabbed the whistle and blew it, and told Chen Qinghan to have peace. There were so many fun things on him, like a jingling cat. After I finished blowing, I walked towards the bridge.

Judging from the location of the bridge head, when the bridge was built, the water level was basically the same as the entrance of the ground cave, and the river beach in front of me should be below the water surface.

I touched the handrail of the bridge head and felt a bit like metal, but if the metal is soaked in water for a long time, the stainless steel will rust. After all, it has been soaked for thousands of years or even longer.

I lifted my foot and stepped on the bridge deck a few times, and found that it didn't shake at all. I found it interesting, so I repeatedly stepped on the bridge deck and jumped a few more times.

I was sure that the bridge was strong enough before I continued to move forward, and the flashlight beam of the five sisters' combination had disappeared without a trace.

I learned from Chen Qinghan. If I wanted to know if the chicken shit was crossing the bridge, I would know just by smelling the bridge deck. The chicken shit was not real shit, so the smell she emitted was different from the stench of the shit.

It smelled like sulfur or some kind of chemical potion, and the hole was full of this smell. I knelt on one knee, leaned my nose close to the bridge deck and smelled it back and forth, and finally smelled a little of her.

Since she really went to the other side of the bridge, I would hurry up and avoid missing the big show to start.

On the other side of the bridge is a stone wall. The huge rock looks like it is cut by a knife, at a right angle of ninety degrees to the river surface.

In the middle of the gap between the two rocks, there is a triangular entrance. Because the distance is too far, this entrance cannot be seen on the other side of the river beach.

I walked into the black entrance, looked at the footprints on the ground, and followed them.

This place has not been visited for many years, and the footprints of the five sisters are particularly clear. After walking for about five minutes, a cloud of light appeared in front of them.

I thought it was wrong. The underground river was lower than the ancient tomb. It was impossible for the exit from the underground world in front of me to be the exit.

When I walked to the exit, I realized that the light was not normal natural light, it seemed to be light, just like the one above the main tomb square.

Sure enough, there was just a "hole" outside, just like an air bubble underground. On the top of the hole, there was a large light bulb that was exactly the same as the main tomb chamber.

It was said to be a light bulb, but it didn't need to be powered on. I suspect that the one in the chicken shit tomb was picked from here.

Standing at the end of the passage, there was mist below. I found the hook claws inserted into the crack of the stone at the edge of the exit, and a rope was connected below. The five sisters should have climbed down the rope.

If it goes down, it will be even further away from the ground. Let’s not talk about the people who built the bridges doing the project here, but just talk about the chicken shit. What did she do here?

The rope was not straightened, and it seemed that no one was on it. I waited for two minutes but the rope had not moved.

My eyes can see things in the dark, but not in the fog. Night vision eyes are not perspective eyes, so I turned on the mini flashlight I carried with me, hung it around my neck, and then slid down the rope of the five sisters.

After sliding for a while, I found something on the cliff, so I stopped and looked at it. I found that it was part of a large machine. To put it more specifically, it seemed to be a slide for an elevator.

The elevator I mentioned is not something like hanging up and down with steel cables, but one with tracks embedded on the wall. I have watched it in a certain movie, but I didn't think about what kind of movie it was.

However, this track has traces of being artificially damaged, either breaking and distorting or missing a piece, which is obviously violently destroyed.

Some people have been here frequently. If the people who were building construction do not want to let people come down, then why don’t they explode together with the bridge? Such a wide underground river cannot be crossed without the bridge. If you take a boat to cross the river, where will the boat be transported in?
