After standing at the entrance of the cave and thinking about it for a long time, Hu Xiaodao turned around and went back.

He didn't leave here and didn't go in, but went back to get a torch.

Hu Xiaodao never expected that the entertainment that was supposed to be unable to sleep at night would take a turning point, and he actually saw something that seemed great here.

After walking back to the camp, Hu Xiaodao, who was one foot deep and one foot shallow, first found a rubber tree at random, dug up some glue with the lid of an iron can, and then used three layers of velvet grass to make a strong torch many times.

He made three or four of these torches one after another, stuffed a lot of burning charcoal into the tin can, covered it with a lid, kicked some fluffy grass on his body, and added a lot of wood to the fire before leaving, and then plunged into the night.

trotted all the way to the cave, the situation was still similar to the beginning, except that the bird's voice was much quieter, Hu Xiaodao did not hesitate at the moment, but plunged into the mine.

Dry - transparent, this is the first feeling of Hu Xiaodao when he first came in.

Putting down the tin can in his hand and opening the lid, Hu Xiaodao picked out the charcoal that was already damp, but there was still a lot of burning underneath.

Drying his hands on his clothes, Hu Xiaodao took out the flannel hidden in his chest and put it on the charcoal and blew it carefully.

"Whew!"

After a while, the fire was burning, and after Hu Xiaodao lit the torch, he could really see the mine clearly.

The height of the entire mine is about three meters, and the two sides and the top of the cave are brackets made of square wood.

I thought it was a gold mine hundreds of years ago, but now it seems that it is not at all.

However, this discovery made Hu Xiaodao excited, the rails didn't seem to be corroded at all, and he had something to build a wooden house by himself, but how to remove the rails made Hu Xiaodao a little headache.

Ignoring it for the time being, Hu Xiaodao casually found two stones to cover the tin can first to prevent it from being stolen by animals such as monkeys, and then walked inside with a torch.

From time to time, a gust of wind blows from the narrow passage, blowing the torches "hissing". This is a good phenomenon, proving that there are other exits to this channel, and we are not afraid to consider the air problem because it is an idea.

After walking almost a hundred meters, the terrain began to steepen, and Hu Xiaodao understood that this was because the terrain here had begun to go down, and this place was actually replaced by railroad tracks, and it was more difficult to walk on both feet.

Fortunately, the rails have sleepers, which can be used as steps temporarily, and Hu Xiaodao tied the unlit torch to his back with a rope, and slowly slid down step by step with his hands alternately holding the torch.

It was unusually cold in the passageway, and some rats "squeaked", probably never seen torches and strangers, circling around with knives.

"Damn, if it weren't for Lao Tzu's special situation now, I would have roasted you all and eaten them!" Hu Xiaodao swallowed his saliva, and the speed of his hands and feet couldn't help but speed up a lot.

It wasn't until fifteen minutes later that Hu Xiaodao's feet stood on the solid ground, which was not as muddy as Hu Xiaodao thought, on the contrary, the entire underground passage was extremely dry, but the gust of wind made Hu Xiaodao feel a little chilly.

Tightening his collar, Hu Xiaodao carefully observed the underground passage.

It can be roughly divided into three directions, because it takes too long to come down from the top, Hu Xiaodao is not clear where the southeast and northwest are down, and can only be distinguished from the pattern.

It is common sense to go up, north, south, left, west, right, east, so Hu Xiaodao currently only has a channel in three directions: the front, that is, the north, the left, the west, and the right, that is, the east.

Similarly, there were railroad tracks installed in all three directions, and Hu Xiaodao didn't know which way to go first, but after a minute, Hu Xiaodao decided to try to take the west side first.

This is completely unintentional, since there is no result, then it is better to go all the way to the dark.

However, Hu Xiaodao did not go in blindly, he deliberately observed for a while before entering, and watched the torch continue to shake before continuing to move forward, if he was out of balance, Hu Xiaodao would not go in at all.

The structure at the bottom is similar to the top, and it seems that people's safety awareness was already very strong decades ago, and there are many anti-collapse facilities with wooden pile structures everywhere, and there are many kerosene lamp shelves inlaid in wood, but the kerosene inside has long since evaporated.

After walking for more than ten minutes, Hu Xiaodao changed to a torch, there was nothing in his hand, and the remaining half of the torch was not thrown, and he found a small secret door after walking a few steps.

Due to the age, this small door is almost mixed with the mountain, and it really can't be found if you don't look carefully, the only difference is that it is recessed into a piece, which makes Hu Xiaodao notice.

I pushed hard, and the dirt on the door kept falling, but the secret door didn't move. Hu Xiaodao looked down and found that the cracks in the door were sealed with mud.

"Boom!"

With a simple and violent kick, Hu Xiaodao's whole person immediately jumped away.

Any strange danger exists in the mine, and if this attempt had not been made, Hu Xiaodao would have long since lost where to bury it and turned into a cup of loess.

After waiting for about thirty seconds, Hu Xiaodao lit the half-section of the torch in his hand and threw it in with a "whew".

Then the dim and fleeting light of the fire, Hu Xiaodao found that there was no danger in the room.

When I came in with a torch, I found that the room was not big, about three meters wide and four meters long, but the height was really not short, it had to be four meters up.

But the strange thing is that the whole room seems to be supported by various thick tree trunks, and even the roof has a few thick logs, and there are dozens of relatively small logs around it, which are completely built according to the standards of the house.

What's the use of building this underground? It's not that Hu Xiaodao doesn't know, but he has too much knowledge and can't think about it.

After thinking about it for nearly 30 seconds, it suddenly dawned on me that this thing was an emergency shelter dug by miners, and they would usually run here in advance to take refuge when they were in danger, so the safety measures were in place.

"Damn, I don't know if there's anything to eat, huh!" Hu Xiaodao threw away the stone axe in his hand and ran over to grab an object on the ground in surprise.

This is a pickaxe, but when Hu Xiaodao grabbed the wooden handle, he found that the wooden handle had completely rotted away, and only had a shape.

However, Hu Xiaodao was not discouraged, the stone axe next to him happened to be still there, Hu Xiaodao took the iron pickaxe and made a few strokes, it was a bit big, this is easy to do, not afraid of big, afraid of you small.

Red jasper is not brought, but there is a pickaxe in the county, and it doesn't matter if there is red jasper or not. Hu Xiaodao took the pickaxe and found a random stone to grind, and after grinding off the rust on it, the sharp pickaxe appeared.

After smoothing out the excess of the stone axe handle where the stone was removed, Hu Xiaodao successfully installed the wooden handle on the pickaxe, so that the artifact of opening the road in the mountains and building bridges in the water was ready.

Happily carrying it on his body, Hu Xiaodao turned around happily twice, but he didn't expect this thing to be really impatient, except for a slightly limited rust, it was quite well preserved.
