I had drunk too much wine in the evening, and I woke up in a daze the next day, and when I looked at my watch, it was time for lunch.

I sat up and touched my brain, and I missed work for a long time, why didn't anyone call me?

When I sat up, I saw that several of them were still lying on the bed, and I didn't panic.

I got up and went to wash my face and brush my teeth, and as I was brushing my teeth, I saw a human face reflected in the mirror of the sink in front of me, standing in the doorway and looking at me.

I was startled by his strange and awkward movements, and immediately looked back, only to see Lao Yin's messy hairstyle, holding the door with one hand, and holding a notebook in the armpit of the other hand, looking at us with a sad face: "Just got up?"

"Aang." I still have foam in my mouth, and I can't speak.

"You don't get up earlier and call Lao Tzu, so I'll sleep until now."

I'm happy in my heart, and there must be no accounts now.

After lunch, we began to figure out how to work on the well.

Again, if it's too simple on land, just get someone to squat there and dig, dig deep, reinforce it, use a ladder up and down, and build a tripod if the ladder can't reach it.

But this well is in the water, and our problem is the sediment that accumulates in the well, and it is unlikely that we can squat in it for a day with a shovel. Moreover, how to deal with the excavated soil and how to deal with the excavated cultural relics are all problems. Lao Yin obviously didn't have much experience in underwater gold and stone, so he brought Lao Zhao and us together to discuss the plan.

Lao Zhao said: "Lao Yin, listen to you say that, this well is deeper than the bottom of the lake? How much deeper? ”

Lao Yin shook his head: "I didn't pay attention, but we shouldn't dive, we won't have a short time to go downstream."

"Measure the depth first, knowing the depth determines how long a person can stay underwater."

Lao Yin nodded in agreement: "Then how to excavate?" Do you have any suggestions? He looked at a few of us who had just graduated: "Did the school teach you underwater gold stones?"

His words made the others laugh for a while, there shouldn't be any academy like this, even the big brother of the Golden Stone Realm.

Lao Yin thought for a while and said: "My idea is this, let's measure the depth in the afternoon, measure the depth, and the other people will first set a professional guide rope, and then get a human sand pump, starting tomorrow, a group of three people, go into the water together, each group is under the bottom for fifteen minutes, one person is responsible for pumping the sand pipe, one person does it below, and the other person helps to pick up the things, and write down the things that come up." Do you think there is a problem with each group once in the morning and in the afternoon, so that there are two dives a day, and the others are on the boat to help filter the sand and stuff in the sand? ”

Although everyone discussed for a while, there was no objection in the end, so they went their separate ways.

In the afternoon, Lao Yin took people to buy things, and I followed Lao Zhao to the lake to measure the depth of the water. This is not a difficult matter, for the scientific investigation of underwater ruins, but I brought a lot of scientific instruments for depth measurement, and there were professionals in the team.

After a while, the average depth of the water was 32 meters. This is a lot deeper than normal water, four or five times deeper.

Lao Zhao's face was obviously not too relaxed, I asked him what was wrong, and he said, "Why did you go so deep?" This depth affects oxygen consumption, and other conditions can occur in people, such as nitrogen intoxication, when diving to about 30 meters, nitrogen intoxication is equivalent to drinking a glass of wine, people will be excited but slow to think, and this symptom will become worse the deeper it is. ”

"It's okay, I'm good at drinking in this gang." This is by no means bragging, after all, after being trained in several gold and stone construction sites, it is impossible not to drink.

Lao Zhao smiled and glanced at me: "You are still a school student, the amount of alcohol is for alcohol, nitrogen drunkenness is for water pressure, and it depends on personal physique and not the amount of alcohol." But you kid should be fine, but I still have to remind everyone. ”

We took a little bit around to test it, and the water around it was not as deep as the well, and the well was in a strange location, it seemed to be the center of the surrounding downhill, and the last time we had to experience it, it was also the only site that was completely exposed, and it was well preserved.

Thinking of this, I felt a little uneasy in my heart, but I couldn't tell what was wrong, so I had to follow the boat back.

The next day, we got on board with a bunch of new guys. There are manpower sand pumps that were just purchased yesterday, as well as many large basins and vats, and a lot of mesh screens, all of which are prepared for cultural relics that may be hidden in the mud and sand.

I and the other two people were put in the first group, wearing diving suits on the boat, Lao Yin installed the sand pump, handed me the pipe and said, "Remember what I just said?" What signal is on and what signal is off? ”

"Remembered."

Lao Zhao also came over and advised: "You guys keep an eye on each other, if anyone is in a bad state, come up directly, don't hesitate."

"Don't worry, let's go!" After saying that, I put on my gear directly, dragged the pipe and skillfully leaned back into the water, and plunged headlong into the turbid water. After so many days, my water is getting better and better.

The three of us followed the guide rope and watched each other's oil lamps maintain the same speed, diving all the way. Last time, I didn't feel it because it was a slow decline, but today I felt that this depth was indeed no joke, and the deeper it was, the depression and fear became a big trouble again, maybe there were a lot of people last time, maybe too excited, but this time they really appeared.

But in any case, Lao Yin put us in the first group, which means that he still believes in our ability, fortunately there are three of us, and no matter how bad it is, there is still an effect on each other.

Finally, when I saw the well circle, I really wanted to breathe a sigh of relief, and my heart finally felt a lot more relaxed. We all gathered to lie down at the wellhead to observe the situation, and the range that the water and oil lamps could illuminate was mud and sand, and we could vaguely see the traces left by some things that had been taken away, presumably from here that the gang took them.

So we each took our positions, and the man in charge of digging leaned into the mouth of the well, because the distance was very close, he didn't take any tools, but directly picked up the mud and sand with his hands, and in a moment the muddy water became even more muddy.

After a while he pulled back and gestured to me, meaning there was too much sand underneath, suck it in. So I inserted a section of the pipe near the sediment, and then told the upper side through the gadgets that Lao Yin had put on the pipe that it was ready to start.

Soon, the pipe began to vibrate, and I tried my best to hold it steady against the mud in the well. It didn't take long for the sand pump to suddenly stop. I was wondering what was going on, when the guy next to me tapped me on the shoulder, and I looked at him, and he gestured to tell me that I was there.

So fast? I'm still addicted to the sand pumping project, and I can't extricate myself, just fifteen minutes? But the thought that the pump stopped at the top might be pinching us a little, so I put the pipe in the well and went back to the surface with them.

I struggled to climb onto the boat and took off my equipment, Lao Yin came over and asked, "How is it?"

I shook the water from my head like a dog and asked him, "Huh? What how? But when I answered the game, I found that something was wrong, and my thinking seemed to have changed a little.

"How's it going down the water?" He looked at me, a little embarrassed.

"It's okay, it's okay, I'll stick the tube under it, just go down and open it directly."

He saw that there was no big problem with us, so he went back to arranging for other people to do the work.

I sat on the side for a few moments before I felt like I was gradually regaining the speed of my thoughts. Unexpectedly, diving can really make people "drunk" and "stupid".

After sitting for a while, we went to help the others with the work, starting to sift things from the mud and sand water that had been pumped up. When I went over, there were already a number of coins that had been mined out next to me, and I looked at them one by one, and it was indeed some Western Han five-baht coins and some distinctive Xinmang coins. It is not surprising that this kind of thing comes out together with the mud and sand, and it is they that show that the abandoned age of this well is indeed the end of the Western Han Dynasty.

I was sifting through the mud when I heard a loud shout from the side of the boat, and the crowd began to stir. I also put down what I was doing and looked over there, not because they had an accident underwater.

However, the cry is not because something is wrong, but because of the excitement of finding something good. One of the three people who went down directly just now surfaced with a bronze vessel and handed it to the people on the boat.

Now everyone gathered around, the appearance of these bronzes is quite "strange", or relatively rare, because most of the bronzes in the collection hall are like a vessel, and these three, two are square plates, one is an iron ring, and the appearance is very peculiar.

I really hadn't seen this kind of bronze before, so I asked Lao Yin, "Do you know these things?"

He shook his head: "I haven't seen it either, there's mud and rust on it, so I'll have to take a look at the rust."

Saying that, he took a board, washed it with water in the basin, wiped it twice with a rag, and the rust was to be removed from the rust later, but there were really a few words on the mud washing board, I had learned ancient characters in school, and the words on it could be recognized as "dragon", "measure", and "children and grandchildren". Judging from the style of the small seal alone, it is full of antiquity and is not very neat.

With such a big tone, and "children and grandchildren", could it be that Qin Shi Huang promulgated the edict of weights and measures?

Before I could express my thoughts, a comrade who had just come up suddenly said, "Don't worry, there's still something down there!"
