Through a period of rest, as well as some treatment of me by Shi Tao, I felt better. The sharp pain just now gradually moved closer to the numbness, and I don't know if this is a good thing or a bad thing, but at least I can stand up on my own now.

I raised my flashlight and shone it around, "Second uncle, what you just said was artificially built?" ”

The second uncle nodded and pointed to the ground, "Look at the ground, it is very smooth, obviously it has been artificially trimmed, otherwise," the second uncle said and looked at me, "If the ground here is as uneven as the crack above, the one you fell just now will be crippled if you don't die!" ”

I touched my back with palpitations, I just fell from the ground on my back, if there was a protruding rock on the ground just now, it would either hurt the spine or the back of the head, if that was the case, I would really be more than lucky!

I swept around with a flashlight, "Second uncle, what kind of place is this?" ”

The second uncle was also a little dazed, "I don't know, but it looks like a road." ”

"Yongdao?" I was a little surprised, "Second uncle, is this an underground tomb?" ”

"I don't think so!" The second uncle touched the wall of the corridor with his hand, "But looking at this workmanship, it is very likely that it is the passage leading to the royal city." Let's move on, maybe the answer lies ahead. ”

Kong Xue looked at both sides of the road, "But which direction should we go?" ”

This is indeed a problem, but the second uncle touched the stone wall, looked at his palm again, then closed his eyes and thought about it, and finally opened his eyes and pointed in a direction, saying, "Go this way!" After speaking, the second uncle himself took the lead in which direction.

We quickly followed the second uncle, to be honest, I was still a little uneasy, after all, it was because we were trapped in the depths of the Black Tower a few days ago because we were in accordance with the judgment of the second uncle. That experience had too much impact on us and left too much impression on us.

I couldn't help but ask the second uncle, "Second uncle, how do you see that you should go this way?" Don't tell me you're pinching your fingers! ”

The second uncle glanced at me, "Fart, I'm still throwing shoes to show the way!" ”

"And how did you come up that you should go this way?" I continued.

The second uncle looked at me, "Do you still need to explain such a simple question?" ”

"My nephew is stupid, you better explain!"

The second uncle snorted, "Alas, the son can't be taught!" Let's go down from that well to here, and the road in front of us should be in a north-south direction, at least this section in front of us. ”

"Holy!" Second Uncle's words surprised me extremely much, and I couldn't help but cry out, "Second Uncle, from above to here, there are twists and turns, especially the crack from top to bottom just now, which has turned many times in the middle, and you can still remember the direction you are facing at this time!" That's amazing! ”

The second uncle smiled slightly, "Big nephew, there are so many things you have to learn here!" In this case, there are generally two ways to judge, the first is to have a strong sense of direction, and every change in direction can be clearly reflected in your mind! ”

After listening to the second uncle's words, the three of us looked at the second uncle's eyes with some admiration, "Second uncle, what about the second method?" ”

The second uncle continued: "This second method is through this. Saying that, the second uncle stretched out his palm, and I suddenly saw a small pocket watch-like thing lying in the palm of the second uncle's palm, "The second way is to look at the compass!" ”

I'll go! I once again had the idea of beating my elders with this kind of rebellion! Kong Xue also exuded a look of disdain.

The second uncle laughed, "I just see that you are too nervous, make a joke with you and relax!" Actually, I didn't rely on a compass either. ”

"Then what do you rely on?"

The second uncle looked at me, "As long as we find the dark river and follow it, we will definitely be able to reach the royal city." ”

I said, "Second uncle, you are teasing us again!" I can indeed hear the sound of water, but there is a reverberation in this place, and I can't even tell which direction the sound of water is coming from, how do you know that? ”

The second uncle pointed to the stone wall next to him, "This is experience, the infiltration and evaporation of water in the dark river will inevitably have a certain impact on the rock formation, so as long as you can judge which direction the water vapor comes from according to the veins and direction on the rock." ”

After listening to the second uncle's words, not only me, but also Shi Tao and Kong Xue nodded convincingly.

With the second uncle's explanation, my heart is also a lot more steady.

As we moved forward, I felt that the sound of the water was getting louder and louder, which showed that there was no problem with the direction of the second uncle's judgment.

Soon we came to the end of the road, and after going out at the end, we turned two corners, and suddenly a larger space appeared in front of us.

I used to think that the passage to the royal city was like a narrow tunnel, but I definitely didn't expect this passage to be huge.

And here we finally see the legendary Tuya Dark River, or rather, one of the Tuya Dark Rivers.

The flow of the dark river is not as large as we imagined, and it is not as turbulent as the current, but it is meandering calmly along the side of this space.

Seeing this scene, I can't help but wonder if the ancient country of Shan Huan rebuilt the course of the underground dark river back then, and what a huge project it would have been for people thousands of years ago!

While marveling at the ability and wisdom of the ancients, I continued along the river. After walking for a while, we gradually found a lot of rock fragments on the ground, as if they were the remains of someone who had built them.

However, we did not see any traces of the work in the vicinity, and we noticed that the closer we got to the stone wall, the more rubble there was, indicating that the rubble must have been excavated from the stone wall.

We looked up along the stone wall and found that there were some artificially excavated caves above the stone wall. These caves are not deep, and some have not even been built.

This makes us wonder why people carved such caves in the rock walls back then.

With these questions in mind, we continued to move forward, and suddenly, Kong Xue pointed to the cave on the stone wall in front of us and shouted, "Look! There's something in there! ”

We hurriedly ran over, following the direction pointed by Kong Xue, we looked up, sure enough, there was a black thing in the cave above the stone wall, but the cave was relatively high, the flashlight was insufficient, and the astigmatism was strong, so I couldn't see what it was, but I felt that the black shadow was a little familiar, as if it was a person!
