Returning to the cold groundwater again, not to mention the feeling, no matter how powerful the lighter is, it is impossible to burn in the water, so after entering the water, my vision is dark again. I had no way of knowing where the chaotic currents would take me, so I struggled to float to the surface and feel the dark winds of the underground river as much as I could.

For the first time, the darkness sharpened the senses, the feeling of the wind on my face, the subtleties of wind speed and size, and I could feel myself getting closer to the wind.

When my body was knocked off the stone wall again, I grabbed a protruding stone, which gave me a brief chance to **. At this opportunity, I lit the lighter and began to observe the surrounding situation, this section of the waterway has widened a lot, so that the current is not as fierce as before, and the flames of the windproof lighter in my hand are no longer as straight and slender as before, but are blown by the wind.

This lighter, which is said to be able to withstand the natural wind of 36 miles per hour, does not appear to be falsely advertised.

I looked upwind, because the lighting range was not strong, so in the distance, I could only see a dark place, and I listened attentively, in addition to the sound of water, I could also hear the whirring wind.

That's right, that upwind outlet should be not far from me, and I'll have to find a way to lean towards it. If you continue to drift through the current, you will want to stop next time, but it will not be so easy.

I couldn't help but look at the place where I grabbed it, the stone wall of this underground river channel has been affected by thousands of years of groundwater, and the surface is very smooth, so it is really surprising to be able to catch this thing this time. I looked closely, and was immediately pleasantly surprised to find that the second half of the underground river was actually a pore structure, and the inside of the stone wall was full of holes, and at a glance, it looked like a miniature version of the cave. And around the periphery of these holes, there are naturally many things of different sizes that can be used for people to grasp.

This is really the blessing of the grandfather, and I have hit the luck.

I put incense on my grandfather in my heart, and then bit the lighter in my mouth.

Because the lighter is placed diagonally, the flame leaks through the metal outlet, and the fire is much weaker, but it can simply free my hand, and I don't have to go out as soon as I let go like a plastic lighter.

In this way, I began to alternate my hands and follow these small stone pillars that I could grasp, which was more strenuous but more stable. My eyes were always on the upwind outlet, and soon, I had a vague sense that there seemed to be a black hole in the place, which was not very clear due to the light, but it was inspiring enough.

However, just as I was about to walk to the upwind in one breath, I suddenly caught a glimpse of something out of the corner of my eye.

The thing was stuck in a small hole in front of me, as if it had been washed down from upstream, floating in the water, pitch black. At first, I didn't realize what it was, but when I took a closer look, I suddenly realized that it was human hair fluttering in the water!

It was supposed to be a woman's long hair, a large clump, hung by a small stone pillar with a long finger in the hole, floating in the water, making people feel numb in the scalp.

How can there be hair in this place? And it's still a woman's hair?

The hair made me feel like someone had thrown their long cut hair into the water, just a lonely mess. If it were on a human head, I might be okay with it, but it's weird to be here on its own.

Could it be that there was once a woman in this place?

Could this be Qiu Huangxi's hair?

I recalled the corpse that was manipulated by Zhou Xuanye before, and there was indeed no hair on its head at all, as if the entire scalp had been ripped off. If the corpse had hair at the time, I wouldn't have mistaken her for Tan Blade.

Thinking of Qiu Huangxi, my heart was a little gloomy, I didn't expect that this time, she and Tan Jian couldn't keep it, I knew that Wang Zehai's three million was so difficult to earn, I really shouldn't take this order. However, what had already happened, what was the use of thinking about it now, I shook off these thoughts and continued to move forward, and within two steps, I found something more.

The reason why it's some, not one, is because there are more things.

It's all small things stuck here, and at a glance, it's all about rags, and even worse, I've found an old-fashioned watch. The appearance of this watch made me immediately realize that this ancient underground river, so far, I am afraid that not only the lives of Qiu Huangxi and Tan Jian have been swallowed, but I am afraid that other people have also been killed!

I immediately remembered the people who dug the snake cave, that group of people dug underground holes**, connected to the ancient water outlet, and it is very likely that they also went down to this underground river to investigate, these things, could they be left by that group of people?

What is the origin of those people?

What are these things for?

Judging from some of the objects stuck here, those people are afraid that they will also be killed.

At first glance, it was all rags, and I couldn't see any other information, so I didn't linger long, and continued to walk towards the outlet. Soon, the black hole appeared in front of me, and the moment I saw it, I almost felt like crying.

The front of the river narrowed, and on the stone wall, a natural stone cave about three meters high was exposed, and a quarter of the stone cave was flooded, but more places were without water. Most of the water rushed down the terrain to the deeper strata, and after I climbed into the cave, I couldn't help but sit on the ground with my butt and gulp my **.

Sitting on the ground, the water did not reach the waist, although it was cold, but after this cold habit, it was not much difficult to suffer. I straightened the lighter in my mouth, the flame was erected, and the light was brighter. ，

The inside of the cave is observed by this light, and the surrounding area is extremely smooth, the result of the erosion of groundwater. Obviously, the groundwater here should also have tidal waves, and the water potential is large and small, and we fell down this time, and the time we encountered it happened to be a period when the water potential was small, so this hole was exposed.

Sitting on the edge of the cave, every now and then, a dark wind blows.

The wind is not loud, but it carries a fresh breath.

At the end of it, there must be an exit!

I only thought about going out to find Zhou Xuanye and the others to meet me quickly, and I didn't care about resting, so I immediately started walking in with a lighter.

As soon as the person stood up, the water level reached the calf, and there was no living thing in the clean and clear groundwater, and there was a sound of rushing water as he walked. The cave ** is damp and cold, the dark wind is slow, and the terrain begins to gradually rise.

Although I don't read much, I still have basic common sense, how does the trend of the stone cave washed out by the groundwater go up? I was thinking about running for my life before, but now with the gradual elevation of the terrain, I suddenly realized that something was wrong.

Soon, my feeling came true. The position I was in before was about forty or fifty meters underground, and the terrain of this cave was slowly going up, so I walked for more than 20 minutes in one breath, and I didn't reach the end.

However, at this time, there was no water inside the cave because of the elevated terrain.

The cave is dry, and the higher you go, more and more artificial traces are revealed.

Before, in the depths of the underground, the stone cave was opened on the stone wall, which was completely a whole, but now that the terrain is raised, its structure is no longer completely stone, but mixed with a lot of earth and stone, and the regular structure is man-made at a glance!

Could it be that those people did a good thing again?

This is obviously impossible, because from the point of view of technology, the technology used in the cave is very primitive, the filled stones, is staggered, this structure, is a relatively old reinforcement structure, although the ability to resist pressure is strong, but because of the time and materials consumed, so after the post-modern era, this technology has long been abolished.

Obviously, this is the work of the ancients.

I thought of the petroglyphs on the stone wall of the water mouth, and my heart said: Could it be that it is also the product of the people of that ancient country? No, now that the water outlet has been made, what are you going to do with the hole in the ground for such a big project? You must know that in ancient times, manpower and equipment could not keep up, and it was not easy to build a hole more than 40 meters deep underground and an overall length of not less than 1 kilometer.

At least, I haven't gotten it to this point.

Just when I was full of doubts, a fork in the road suddenly appeared in front of me, one to the left, one to the right, and the fork in the road where I am now formed, forming a T-shape.

At the same time, there were three words on the stone wall in front of me.

Go to the right.

The characters are traditional Chinese characters.

If this cave is left by the ancient civilization of the Western Regions, then how can there be traditional Chinese characters in the cave?

Who left this word?
