Back in the room, Professor Chen stood in front of the windowsill, looked at the night scene outside, and said with emotion: "Lao Zhang, we have only been here for a few days, and we have made so much trouble. ”

Zhang Gong walked up to Professor Chen with a smile, pointed to a flash of light by the lake and said: "Look at those lights, they are very bright, no matter what the weather, they are still there, releasing brilliance, and what really changes is that they are reflected in the lake, sometimes swaying on the sparkling lake, sometimes up and down, but no matter what, those lights are still lights." ”

"Haha, it's sour again! But what do you mean now? ”

"What I'm trying to say is that here, you need to be the same."

Professor Chen nodded and said, "Indeed, it seems that the water here is very deep, and it may be best for us to stick to ourselves." ”

"Now the overseas tomb robbers have escaped, but there are still other tomb robbers around us, since we can't do every step of prevention, let's just do our best."

"I've analyzed today's events, and those who can know the organ must have come into contact with the core person of the tomb guard, and this signal is not simple."

"Don't worry, this won't be the grave keeper guarding and stealing it, if that's the case, they would have emptied this place a long time ago, so why should they still stick here?"

"Yes, I also ruled out this, I think a certain grave keeper was used, this is more likely."

"Lao Chen, I have a hunch that something big will happen in the next few days!"

"Where do you feel about it?"

"I can't tell you exactly where it came from, but when I was trapped in the afternoon, I suddenly felt a lot of noise around me, which is not a good sign."

"I'm also thinking, although there are more people used this time, and they are more miscellaneous, but the proportion will not be high, even if there may be bad elements in our team, there will not be many of them, I think there will be four or five at most, let's not consider those first, the boat will naturally go straight to the bridge! However, now it seems that Lao Lei had to let Situ Fang and a few of them come over, it seems that he is still quite far-sighted, without their help, this time, we are enough to choke! ”

"Yes, if it weren't for them, maybe we would have been reimbursed here, so Lao Lei's favor went back and made up for it."

"Don't talk about the distance, let's talk about now, how do you plan for tomorrow?"

"At work? Then you have to ask, go directly from the bottom, Situ Fang and Zhijun have already found a suspected passage in the afternoon. ”

"Are you sure?"

"It's basically certain, I have read a few images saved on the imager, and I can't be wrong; Through this tomb, I found out that Zhijun is also quite perceptive in this regard. ”

"If you have a good understanding, I'm afraid that his heart will be crooked, so you have to watch more."

"From tomorrow, I will take them with me, after all, they are young, and it is the first time they have gone to the tomb, and the first time they have seen too many gold and silver treasures, it is inevitable that they will be confused."

The next morning, because there were not many people to go down to the bottom of the pool, so a lot of archaeological personnel were streamlined, and in addition to the necessary police force and security, Professor Chen took several archaeological team members, accompanied by the expedition team and the police, to start a new day's work in a low-key manner. After going down to the bottom of the pool one by one, looking at the blood cell sediment at the bottom of the pool, it is like a red warning sign, which makes every newcomer look a little unnatural and feel particularly nervous.

Inside, under the leadership of Situ Fang, the group soon came to the suspected entrance: a stone nearly three meters high.

Professor Chen looked around, and there were traces of artificial excavation everywhere, which looked very smooth. And such a large rock standing here is a bit eye-catching, and it looks particularly incongruous with the surrounding environment. Zhang Gong personally probed and confirmed that behind it was the channel they were looking for. Looking at the big stone, Situ Fang called all the expedition members and pushed it hard, but the stone was as if it had taken root, and it didn't move at all.

Zhang Gong looked at Situ Fang, who was sweating profusely, and said with a smile: "This stone will definitely not be pushed, otherwise the impact of the water flow is so great, it should have been washed aside, look patiently for it, see where there is something unreasonable, find it, and basically find the mechanism button." ”

After listening to Zhang Gong's guidance, Situ Fang and the others searched all around the stone, but did not find anything suspicious.

Situ Fang accepted Professor Chen's prompting, and after climbing the bridge to the rock, he really found a small round stone on it. With Professor Chen's permission, he pushed the raised stone into it with all his might. With a "pop" under Situ Fang's feet, the huge stone slowly fanned out and moved to the right side.

Situ Fang jumped off the stone, stood in front of the entrance of this passage, and shone it with a flashlight, and found that there were steps inside, which extended steeply all the way up, probably because it was soaked in water all year round, and it looked wet inside. He cautiously climbed up for two minutes, and when he noticed that the air inside didn't seem to be very good, he retreated.

Professor Chen listened to Situ Fang's introduction, went to the passage and looked at it again, and then said to everyone: "The air circulation here is very slow, we will rest here, and we will go in again in twenty minutes." ”

After speaking, he pulled Zhang Gong to look at a few outlets. These outlets are cleverly designed, with a trapezoidal shape about two meters high and three meters lower. Professor Chen slid down and looked at the core part, that is, the gate responsible for the blocking task, which was a stone that had been carefully polished into a trapezoidal shape by craftsmen, about four meters thick, in the shape of a small front and a wide back; The back is connected by a one-meter-square stone strip that leads to the inside of the mountain. The base part is also polished into a matching shape, which is also small in the front and wide in the back. When you want to block, the stone that bears the role of the gate is pushed out by the stone strip behind, and the effect of water pressure will be pushed up to the front, which is blocked seamlessly, and when you want to release water, you can drag the central part to the back through the lever at the back.

Chen Zhijun looked at the big drain and asked, "Dad, this is a water conservancy facility?" ”

Professor Chen smiled and introduced, "Yes, this is one of the water conservancy facilities of the pool, which is responsible for intercepting the water and controlling the direction of the water flow. ”

"So how does it get the water out? How did you get the water in? ”

"Do you see this one-metre-square pit in front of me? This is what the flood is for, when the middle gate is brought to the back, this flood outlet is exposed, and the water naturally flows through it to the underground river; If you want to fill it with water, you need to move the large gate in the middle forward, and after covering this opening, there should be another opening behind it, which must be connected to the water storage hole above, in that case, the water in the water storage hole will be poured into it, simply put, the gate plays the role of hole switching. ”

"But how can this stone hold down so much water in the water storage hole? How can the water not leak out? ”

"This is the ingenuity of the design, in addition to the gravity factor of the stone itself, the top of this gate is actually very tight, so that the water pressure can not open the stone in the middle, in addition, you take a closer look, it is not completely leaky, but it is relatively small, after all, the sealing of this kind of sluice is poor."
