World Tibet Bureau

Xia Xi looked helpless and rolled her eyes: "Brother, I never did this kind of hard work before. I always stood aside and guided. Now it's better. I have to do everything myself. They are a bunch of useless things."

Complaints are complaints.

But he still had to do the work.

After all, among the few of us, besides being able to beat Lu Senyin, even Hao An can kill him.

To be honest, we have to thank Qubi and other tea horse merchants. The tools they left behind have been useful several times. Otherwise, if we had to dig with our bare hands, we really don’t know how long it would take to dig.

Xia Xi took the shovel and knocked around first. He leaned down to listen to the sound. Maybe he couldn't hear the sound clearly and didn't know where was the easiest place to start. He then used the shovel to smooth the soil on top.

Very flat.

It’s almost the same as leveling the bathroom during renovation.

Xia Xi asked me: "Is there still water?"

I replied: "No more."

Xia Xi frowned, turned to Lu Senyin and Xiaozhu and said, "Two beautiful ladies, please leave for a while."

Xiaozhu asked: "Brother Xia, what do you want to do?"

Xia Xi replied: "Brother Liu, you have to pee and take care of yourself."

President Liu: "..."

Lu Cenyin said: "He should be measuring the location. Let's go."

The two of them stayed far away.

President Liu said: "Why do you have to come from me? Can't you do it yourself?"

Xia Xi explained: "I didn't! Besides, I'm so tired that I asked you to pee. What's wrong?"

President Liu turned to look at Hao An and me again.

We all said no.

President Liu had no choice but to untie his belt, half way through it, and turned to us and said, "Guys, please turn around to avoid the psychological shadow caused by low self-esteem in the future."

I said: "Are you going to lie or not?!"

President Liu was so angry at me that he stopped nagging and began to prepare to release water on the place that Xia Xi had smoothed before.

I said, "Wait! I still have a water bag on me!"

President Liu had a frustrated expression on his face: "Why didn't you tell me earlier? My pants are all off!"

I said, "Sorry, I just found out!"

I really didn’t mean to tease Old Liu.

I didn't realize just now that I still had two-thirds of a water bag filled with water.

President Liu was so angry that he had no choice but to pull up his pants and run away to let the water go.

Xia Xi took the water bag and spread it evenly in circles on the leveling ground. Then he stared at the water seepage. After staring for a while, he reached down to dig the soil not far from pouring the water. The soil is slimy.

I didn't know what this principle was at the time.

Xia Xi later gave a relatively simple and easy-to-understand analogy.

Nowadays, everyone's bathrooms are waterproofed. First, apply a layer of waterproof paint to prevent water from penetrating downstairs. Then, apply a layer of mud and sand mixture on top of the waterproof paint, and finally put ceramic tiles on top of the mud and sand mixture. But many times, there is no water leakage downstairs, but the wall outside your bathroom will peel off and become moldy.

This is called anti-alkali phenomenon.

What's the reason? The water in the bathroom leaks through the gaps in the floor tiles and reaches the second layer of silt and sand mixture. However, because the third layer of waterproof coating is water-proof, the water can only flow slowly from the silt and sand mixture to the tiles outside the bathroom. In the silt mixture below, water vapor gradually rises, causing the wall to become alkaline.

Xia Xi said that this kind of earth-covering seal also has a barrier under it, which is usually a flat stone slab. Since it does not seep water, it can be regarded as the bottom waterproof layer. Water will flow when it pours on the covering earth above. You can observe the water covering the earth next to it. Based on the seepage situation, you can roughly determine the size of the stone slab that can block water, so you can easily find the position for shoveling.

Anyway, chickens don’t pee, they all have their own ways.

Xia Xi's method had immediate results.

He threw away the soil in his hand and drew an area: "This is it!"

Only ten minutes.

The soil is dug up.

The shovel just happened to be inserted into the gap of a stone slab.

Everyone was overjoyed and worked hard together, shouting: "Get up!"

There was a "click".

A stone slab measuring one and a half meters square was lifted up and opened by us.

A dark hole was revealed underneath.

President Liu wanted to go down, but was stopped by Xia Xi.

Xia Xi said: "Old Liu, are you rushing to reincarnate?"

President Liu asked: "How do you say that?"

Xia Xi replied: "According to speculation, this thing was last launched in the Tang Dynasty. How many years has it been?"

"If there is no oxygen, there are organs, or poisonous gas is hidden inside, who will be the president of the Cultural Preservation Association, who will play with your antiques, and who will keep Dr. Fu's bed warm?"

President Liu waved his fan: "Brother Xia, you are right!"

Xia Xi took the rope that had been strung together with the bones and hung it down first, asking us to get out of the way. The other person stood at a position away from the entrance of the cave and swayed wildly for a while without triggering any mechanism.

Followed by.

He took another Pu'er tea from Hao An, wrapped it into a ball with paper, tied it to the end of a rope, lit the tea bag, and put it down.

Waited five or six minutes.

The rope was pulled up again.

The tea bag above burned very fully, proving that there was no problem with oxygen.

Xia Xi said: "It's over! You can go down now!"

Chairman Liu asked: "Is it possible to test whether it is poisonous?"

Xia Xi smiled and said: "Old Liu, don't question me on this! Since the oxygen below is flowing, even if there is poisonous gas inside, it must be flowing. So many years have passed, why does the bird poisonous gas not disappear? ?”

"This is the so-called poison without oxygen and non-toxic with oxygen. For example, if you and Dr. Fu can have a child, you will definitely not be a eunuch. Of course, if you insist on claiming that the child was born by Lao Wang next door, I have nothing to say. It’s okay to say it.”

President Liu: "..."

Xia Xi held the entrance of the hole with her hands first, and then tested it with her feet.

"I'll go! There are actually mud steps for people to go down here...but they don't seem to be very tight."

"Oh shit!" (End of chapter)
