Bai Yutang was touching Yinxue in the room just now, and Xiaowu followed him in. The fifth master touched Yinxue, and Xiaowu also put his head in Yinxue's belly, and then Yinxue raised his paw and patted it.

Xiaowu took a few steps back, shook his head and continued to rub against his wife, and continued to be beaten.

The fifth master saw the two tigers playing around, their big paws gently touching each other.

Xingyue walked to Bai Yutang and lay down against him, wagging her tail slightly.

Fifth Master touched his round ears... Judging from Xingyue's age, they were probably all children.

When Bai Yutang snores Xingyue's head, it's not like snoring Xiaowu, he does it gently...

"Gently..." Bai Yutang muttered a few words to himself, then suddenly stood up and ran out quickly.

Zhan Zhao was about to imitate the cat meow of the Demon King. He just cleared his throat and before he could speak, Bai Yutang rushed over and said to him, "I know what mechanism is in the well!"

After Master Wu finished speaking, everyone else also looked over.

Zhan Zhao narrowed his eyes, raised the corners of his mouth, and held the fifth master's face with both hands, "Genius!"

Everyone around was stunned for a while, and Lin Yehuo whispered to Zou Liang, "I thought he was going to kiss him on the face."

Zou Liang also nodded.

Gongsun also asked Zhao Pu in a low voice, "What agency?"

Zhao Pu shrugged--I haven't said this yet.

Ryotatsu Meiya tilted her head - Didn't you say she was a genius?

Fang Tianyue crossed his arms and nodded - praise first and then talk about it, you can’t be wrong!

Zhan Zhao held the fifth master's face and shook it around, praising him as the smartest.

Everyone is so anxious, why can’t they just move their hands and not speak?

Yin Hou asked Tianzun - is it really cracked?

Tianzun raised his chin - Of course, my Yutang is the mechanism terminator! I have learned to pick locks since I was a child!

The Demon King and the others all looked at him speechlessly - You still have the nerve to say that!

After showing off enough, he asked Mr. Wu how to crack it.

The fifth master said that he wanted to go to the Xu family.

Everyone followed him to the Xu family's old house.

When he came to the well, Bai Yutang opened the manhole cover, picked up a brick from the ground, and threw it into the well.

Everyone looked at Bai Yutang.

The Fifth Master nodded and said, "Let's go back first. We won't be able to see it until tomorrow morning."

After saying that, he asked Zhao Pu to ask the shadow guard to go to the prince's mansion and throw a brick of similar size into the well.

Everyone roared again and followed Bai Yutang back.

After getting into bed, even though it was getting late, no one was sleepy, but Master Wu slept very well...

Early the next morning, before dawn, Zhan Zhao heard someone banging on the door. He ran to open it, and a group of children came running in from the door.

Liangchen Meijing rushed into the room and grabbed the edge of the bed to tell Bai Yutang, who had just gotten up, to get dressed quickly.

Master Wu asked them all to go to Xu's house. There should be no water in the well.

A few children rushed out and told some adults in the yard, and the group of people returned to the Xu family's old house - and sure enough, the well in the old house became an empty well again.

At the same time, Prince Zhai's Mansion also sent people to tell Zhao Pu that the well was empty and there was no water left.

Bai Yutang also came to the empty well.

Everyone looked at Master Wu curiously - what's going on? So the key to unlocking the mechanism is a brick? "

Fifth Master waved his hand, "The key to unlocking this mechanism is lightness!"

"Light?" Everyone was confused.

Mr. Wu nodded, "This well is two wells nested together. The walls of the small well inside are permeable to water, while the walls of the well outside are impermeable. The bottom of this well is like

There is a relatively large space below a plug, which is just for the lifting and lowering of the external well. Normally, the external well sinks. Once something lighter falls to the bottom of the well, the plug at the bottom of the well will sink a little.

At this time, the water on both sides of the well wall will flow into the underground space, and the water-impermeable outer well wall will float. After all the outer well walls float, the bottom will be tightly closed, and the well will be empty. At this time, there is no water

In the well, this stone is heavier than when it was just thrown into the water. It just holds the bottom of the well. Even if someone goes down, it will still hold the bottom of the well. But once this stone is taken away

When it comes up, the outer waterproof well wall will drop down a little, and water will seep in from the well wall again until the water level reaches a balance point again and the well is full again."

After Master Wu finished speaking, everyone looked up and imagined this scene - what kind of outer well and inner well, waterproof or not...

Mr. Wu is in a hurry - don't you understand?

Everyone seemed to understand but also seemed not to understand.

At this time, the fourth child raised his hand and said, "I understand!"

Everyone looked at Xiaotuanzi and said - everyone should be able to understand the truth, can you explain it more clearly and simply, without going around in circles.

The fourth boy cleared his throat and volunteered to explain to everyone, "That is to say, are there two identical wells? There is a waterproof cover on the top one. When the water above is full, the cover will fall on top if it sinks.

The well is empty. And at this time, there is a heavy object pressing down on the stopper in the empty well above, which happens to be a cup. When the heavy object is taken away, the bottom of the cup leaks, and the water returns to the top.

In the well, the outer cover will sink again and fall to

Everyone stared at the little fourth son - he seemed to understand a little more, but also seemed a little more confused.

Bai Yutang nodded aside - that's what the fourth son said, it's easy to understand!

Everyone looked at the two of them in confusion - you two call this easy to understand? You two have the brains to break down the nine-link chain, can you talk so convolutedly?

Both Xiao Sizi and Bai Yutang were dissatisfied - he made it so clear!

Everyone looks at Zhan Zhao and Gongsun - you two use love to understand each other.

Zhan Zhao and Gongsun both smiled and tilted their heads - Oh, Xiao Bai Tang | Xiao Tuanzi... smart and handsome | cute!

Everyone wanted to beat them both.

The Demon King shook his head. These two children had a clear mind, but their mouths were weak.

The old man waved to everyone, and let me explain it to you. "To put it simply, imagine that there are three wells in total, all in the shape of three cups. The top well is a small cup, and a cup with water seepage. The bottom of the cup is

It's a stopper. The stopper is in the shape of a round "I", with a small top and a big bottom. The bottom of the small cup is actually not tightly slit. The other end is just the same. The ring is just right. When the well is full of water, it maintains a state of water on top and empty on the bottom.

.As soon as the stopper is loosened, the medium cup will rise, and the water in the small cup will flow to the small cup. The bottom of the stopper just covers the medium cup. In this way, the small cup will be empty, and the surrounding water will be blocked by the medium cup.

Go. At this time, the stopper is stuck by the stone above and the floating medium cup. But if the stone is taken away, the stopper will also float, and the surrounding water will flow along the bottom of the medium cup until the small cup is reached.

As soon as there is water in the small cup, the water in the large cup will be slowly drained out, and the medium cup will gradually sink, eventually returning to the state of being full of water but empty again."

After explanations by three people and drawings and demonstrations, everyone finally understood the mechanism.

Gongsun nodded, "No wonder the water level fluctuates high and low, because when the top water is empty and the bottom is empty, the plug at the bottom always sticks to the medium-sized cup, no matter whether the cup floats or sinks,

Its size is just right with the bottom of the plug, but the upper part of the plug and the small cup, which is the bottom of the well, are actually not tightly sealed and may even float up and down. The sound may be the plug floating up and down.

Caused by hitting the well wall?"

"The white silk was probably hanging somewhere outside the bottom of the well. It was indeed hung with a piece of silk. It was washed into the bottom of the well with the water flow, and then washed out again..." Zhan Zhao also analyzed, "The skull

, maybe the stopper sank when the stone fell. And the skeleton was right next to the gap... When the boy fell into the water, he said he felt like there were vines or ropes wrapped around his legs... maybe it was a piece of white silk? For example,

The deceased was a woman dressed in white, and the body is outside the well?"

Everyone thought it was possible, but once the mechanism was cracked, a new problem arose.

"This mechanism... doesn't seem to be of much use!" Tianzun couldn't help but say.

Everyone also nodded, because as long as someone goes down, they will definitely step on the plug at the bottom of the well... Although the well will be empty by then, there will be water under and around the well. Even if the well and its walls are violently demolished, the water outside will still be there.

It's such a complicated mechanism, but it doesn't seem to have much use... What is it used for? Moreover, the flow rate of this water is also very slow, and it takes an entire night to control the water. If the skeletons can rush in, it means

When the gap is at its largest, it may be quite big... How much water is flowing? Is the underground water system complicated?

Zhao Pu also felt that it was unnecessary to take off his pants and fart... It would be great if it were a mechanism created through a well that extends in all directions... But this mechanism seems to only be able to pass water but not people, so what is it used for?

Zhan Zhao thought for a while and asked, "If there is really a female corpse besides this skeleton, then she can only be in the waterway outside the well, right?"

Everyone nodded.

"Then...this well is an octagonal one...if we dig around, can we find the body?"

Zhan Zhao's words made everyone stunned.

Bai Yutang suddenly looked at him.

Zhan Zhao blinked - what did I say?

This time it was Bai Yutang's turn to reach out and hold Zhan Zhao's face, "Cat! Genius!"

Zhan Zhaoda's eyes lit up - Really?! Am I a genius too?

The Demon King also touched his chin, "...

Zhao Pu asked the shadow guard to bring a map and marked the locations of several related wells. After careful observation, he found that these wells were built with eight sides according to the directions. The side with leaves was exactly north.

The other directions are also very accurate.

Zhao Pu connected several wells that he had discovered and found that facing in different directions can form a very complex water system, and they are all connected to different rivers, lakes and pools...

"The underground water system!" Zhao Pu said, "These wells are the coordinates of the underground water system connected to Kaifeng City! And that complicated mechanism is used to adjust the water levels in the water channels!"
