I measured the distance between the stone steps with my eyes, and the difference in height was about one meter apart.

At this distance, there is no problem to step on, but if there is moss on these rocks, or something slippery, it is difficult to balance the stride movement, and the consequences are very serious.

Of course, we had another option, which was not to take the stone steps, but to go down the rope ladder ourselves. But this approach was quickly dismissed - the height here was so high that there was no bottom in sight.

I asked Xiao Shirong, "What do you think we are going to do?"

He said, "Go on, do you still need to ask?"

"Aren't you afraid of falling?"

"No, I'm not as timid as you." As he spoke, he took an iron cone in his hand, stepped out, and with a "bang" he knocked a hole diagonally down in the crack of the brick wall, and then used it as a support to step up the second stone step very easily.

I'm secretly surprised that this guy's strength is so great? In this way, it is much simpler, even if your feet are slippery, as long as you can get strength in your hands, you don't have to worry about flying down.

So I asked Xiao Shirong's subordinates to ask for an iron cone, and I walked up like him. Luckily, everything wasn't as difficult as I thought, and the stones themselves weren't very smooth, and the friction was enough to stand on them.

In this way, we went down the stairs, but it was a smooth one.

From time to time, murals appear on the surrounding walls, and their contents are exactly as I guessed, showing the great achievements of Gaozu's life. I remember that many of the Han Dynasty tombs excavated in other places are historical stories, such as the "Hongmen Banquet". And Gaozu himself is a "historical figure", he has already experienced many historical events, so it is not surprising that the content of the mural is so. It can be seen that although the style of the murals here is out of step with the times, the content does not break through the limitations of the times.

In addition to the murals on the walls, there are also one or two "ear chambers" from time to time, which should be regarded as ear chambers.

Some are alone, some are two connected, providing us with a safe place to rest. In these ear chambers, without exception, there are a lot of treasures, there are many specific types, I didn't look carefully, but the color alone is to know that gold, silver, jade, bronze, lacquer is a lot, large and small, different shapes, some particularly eye-catching is the realistic animal modeling, character modeling, the most should be daily utensils, people just look good to feel luxurious. But I haven't seen this kind of scene once or twice, but it's not enough to make me very excited.

And Xiao Shirong and his men seemed to be more calm than me, turning a blind eye to all kinds of cultural relics, and even when we were resting in an ear room, they kicked the gold cakes on the ground one by one like stones, and then sat on the ground.

This scene made me very puzzled, it stands to reason that the gold cake is the easiest of these things, it occupies a small area, and the gold density is also high, and it is easy to walk a few times, but they didn't take it.

I couldn't help pretending to tease Xiao Shirong and said, "Yo, there are so many treasures, don't you even look down on them?"

He replied, "We are not tomb robbers, and it is useless to take them back from here."

Even though he said that, he still felt unreliable. Can't those things in his house really be handed down from his ancestors? And these well-trained subordinates with their own abilities, what else can they do when they are trained? Forget it, don't think about it, let's rest.

I also sat down on the ground, and to be honest, it was quite tiring to walk on my legs and waist like this, especially with my hands holding on to the wall all the time. I leaned my back against a large piece of gold, which curved just enough against my waist and felt very comfortable.

I shook my hands hard, stretched my waist, stretched my legs, and then I felt relaxed. I don't know how many people have ever dreamed of sleeping with gold in their arms, but today I am lying on gold.

Maybe I didn't really rest all the way in, but I was almost asleep in a daze just sitting like this.

Half-asleep, I felt something on my face that was itching, and my first reaction was not a mosquito, and I slapped it, and then an unusually bad smell entered my nose.

When I photographed it, I realized that it shouldn't be a mosquito, and I opened my eyes and saw that my hands were sticky with the body of a half-exoskeleton insect. A wave of nausea immediately welled up. I quickly wiped my face with my sleeve, took out the water from my bag, and washed it for a while.

When he finished his work, he found Xiao Shirong sitting there watching, with his trademark contemptuous smile on his face.

"What do you see, what's there to see."

"It's just a little bug, are you there?"

"I ...... Don't worry, I'll throw it in your face when I catch it. ”

"If you can throw it, you can give it a try."

Although it was a little uncomfortable to be crawled by insects, at least this shows that there are living creatures here, so it should still be suitable for survival, and we don't have to worry too much about the environment. I used to hear about tomb robbers who went into the ancient tombs and were suffocated to death and smoked to death, and we were lucky at this point.

Almost after resting, we continued our downward journey.

The temperature around it continued to rise, and from time to time there was the same white steam rising. I couldn't help but wonder what the hell was going on here. Why is there always steam? There's no way anyone is cooking on a fire underground.

After an unknown number of laps, I was tired again, looking up, I couldn't see the top anymore, and when I looked down, there was no bottom. This feeling of not being able to reach the world and the earth makes me feel as if I am in an abnormal space like the ovary tomb again, and there is nothing else related to the normal world except for the stone walls, stone steps, and burial goods.

Fortunately, there is an ear room for us to rest, I wonder if the ovary has been designed to take into account this height, if not let people rest, it is too inhumane.

In fact, I am still pondering another problem, people say that it is easy to go up the mountain and difficult to go down, but when I actually climb the mountain, most of them are still difficult to go up the mountain, and the effort required to go down the mountain is far less than that of going up the mountain. We've already had so much trouble coming down that when the time comes, we don't know how tired we will become. No wonder the Madao people have prepared so many supplies for us, it seems that this is still a protracted battle.

We rested three more times and finally took off our winter clothes into summer clothes in a few ear chambers – it was so hot that I started to sweat even when I was standing. Xiao Shirong's subordinate with a thermometer looked at it again and told us that the temperature was already in the thirties.

It stands to reason that the temperature under the ground is a little higher than the surface, but if I remember correctly, it should have dropped by 100 meters and warmed up by 3 degrees Celsius. But since we came down, we have risen from minus to more than 30, that is to say, at least a thousand meters down? I don't think so.

For example, 100 meters, if you are on the playground, 100 meters is one side of the playground, but if you put it up, a 100-meter building can have more than 30 floors, and it is enough to mark it in a small place.

The reason why I was impressed by this was because when I was still in junior high school, the art teacher took us out to teach us this principle, and also let us observe the teaching building and the playground.

From the time we came in, maybe the cave was a little downward at first, but the main thing was this part of the road. Although I can't clearly calculate how many floors there are, 1,000 meters is equivalent to more than 300 floors, and this kind of building should not have existed in the world. So there must be another reason for this heat.

We walked down a little further distance, and finally confirmed my idea that there was a heat source down there. There's more white steam, it's hotter, and there's even some smell in the air. Relying on my vision, I first noticed that directly below us was an underground hot spring.

I pointed it out to the others, and they used oil lamps to shine over there, and they saw that the oil lamps passed through the mist and went directly into the water, and the water was still very clear.

I thought I knew I was jumping straight down, and it took so much effort. But if you think about it, if the temperature in the water is higher, it won't be a good thing to jump.

We walked down a little further, and I felt that the temperature of the hot spring must not be suitable for bathing, and there were still more than ten meters away, and I felt that the heat was blowing.

We stopped at the stone steps and looked down at the hot springs, we didn't come here to find it, but it was the only way we had to go.

And there are obvious traces of artificial transformation around the hot spring, from my point of view, there seems to be a huge iron tool in the hot spring, like a large cauldron, and there are many other parts around, some on the water, some under the water, like a large machine.

Others apparently noticed the problem as well, and kept shining oil lamps on and off for some observation. However, just as we were staring intently at the thing, there was a grunt, then a clatter, and then a pop. The large machine suddenly moved.

I can't say it in my heart, is it something wrong again? But after waiting for a while, nothing happened. All was quiet again. I thought to myself, whether it was a mechanism or something else, I still couldn't see it clearly at this distance, so I motioned to Xiao Shirong for us to go down a little longer.
