In the water under the well, there is a brick that is significantly different in color from the others.

The brick is the same brick, but because the other bricks are obviously covered with microorganisms in the water caused by soaking in water all year round, but this brick is much cleaner.

Shi Lei also felt a little strange, after all, according to Mr. Zheng, after he was born, he completely lost the news of the antiques in the old mansion, which means that no one knows the secret of the bottom of the well for at least seventy or eighty years, and no one will be able to open the mechanism at the bottom of the well again, so this brick in this well should not be kept so clean.

Could it be that Mr. Zheng doesn't know where the secret is, and his children actually know it, and the things under this are long gone?

For this brick, Shi Lei didn't dare to act rashly, he had to know more about the situation here, so he surrounded the brick and beat on the surrounding bricks, hoping to understand what kind of mechanism was hidden behind this brick.

And with his behavior, Shi Lei also discovered another possibility, not that someone had touched the brick recently, but because of the current.

Although he is underwater, Shi Lei cannot accurately grasp the direction of the water flow, and in such a cramped space at the bottom of the well, the water flow is actually rotating slightly, which makes it even more difficult to judge the water flow.

However, Shi Lei found that the speed of water near the brick seemed to be faster than in other locations.

To do this, he examined the speed of the water at different points at the bottom of the well, relying on his own skin, and finally determined that the water was flowing faster near the bricks.

Although, this kind of speed is actually only minimal, if it weren't for Shi Lei's frequent use of tactile cards, his own sense of touch is far more sensitive than ordinary people, and he can't feel it.

The water continued to wash the brick, making it difficult for microorganisms to stay on the surface of the brick. Of course, this flow of water does not feel much to humans, but for those microorganisms, it is no different from the surging river water.

Shi Lei suddenly had an idea in his heart, this is not a well at all, but a ......

He immediately took off his oxygen mask and tasted the water from a well, which was not sweet at all, but had a slight rotten taste.

Putting on the oxygen mask again, Shi Lei stayed underwater and thought.

This well can't lead directly to the river in the backyard. So, the well water is actually the river water, which perfectly explains why the well water smells of rot, and that's the smell of the river water.

Shi Lei floated up a bit, letting his head rush out of the water, and then, he found that there were obviously some unusual marks on the wall of the well.

These marks do not have a clear dividing line, but are reduced little by little from top to bottom.

At the top of the well, the walls of the well are covered with moss, and the further down you go, the less moss there is, and there will be no moss below the surface of the water.

This gave Shi Lei a more intuitive understanding.

That is, the river adjacent to the backyard also has a much lower water level than it did a few decades ago, which is an extremely long process, and the water level is constantly decreasing, which can be seen from the height of the embankment.

The decrease in the water level of the river also led to the decrease in the water level of the well, which is more proof that the well is the one that leads to the river at all.

Thinking about this, Shi Lei was much bolder, he directly stabbed down, found the brick, pushed it in, the brick did not move at all, Shi Lei took out a special tool from his body, and inserted it directly into the gap around the brick.

With the force of his wrist, the brick moved out a little, and Shi Lei immediately felt that the water flow near the brick was much faster.

Little by little, the brick was pulled out, and with each point, the water around the brick became more turbulent.

The bricks were finally cut out about a centimeter wide, which was already the width that Shi Lei could directly grasp with his hands.

So, he grabbed the brick and pumped it out.

It's very laborious, probably related to the fact that no one has touched this brick for at least seventy or eighty years, but the brick was still pulled out by Shi Lei little by little.

When Shi Lei felt a noticeable loosening of his hand, which meant that the brick had been fully moved, Shi Lei immediately stopped moving.

No one knows if the brick will trigger other mechanisms after it is completely pulled out, Shi Lei must be more cautious, he needs to continue to study this brick.

took out a strong flashlight, and Shi Lei shone it in along the brick crack of the brick.

The brick joints are very narrow, but Shi Lei's eyesight is much more than ordinary people, and with the light of the strong flashlight, Shi Lei still sees some clues inside.

Once he saw the part, Shi Lei was able to rely on his strong knowledge of mechanical application to understand the mechanism in the well more completely.

The result of the judgment is that there is no danger, and this is a very ordinary mechanism.

Because the mechanism has been set up to be secretive enough, the creator of the mechanism did not make any offensive or defensive means for this mechanism, after all, except for Shi Lei, I am afraid that no one has the ability to discover the location of this mechanism.

After confirming that there was no danger, Shi Lei directly pulled out the bricks.

Suddenly, all the water in the well was poured into the gap, and a strong suction force acted around Shi Lei's body.

Shi Lei couldn't help but feel a little strange, such a big suction, even he couldn't bear it, such an ordinary person, if he wanted to open this mechanism, wouldn't he have to suffer from it?

Before he had time to think about it, the water in the well soon flowed out of the gap, and the water level in the well soon dropped to the lower edge of the brick.

At this time, Shi Lei felt that the well seemed to be shaking, he secretly said that it was not good, and hurriedly pressed the remote control in his hand, and the electric pulley group above immediately worked, and the steel cable tied to Shi Lei's body dragged Shi Lei's body up quickly.

In the process of rising, Shi Lei saw the bottom of the well under his feet, slowly spreading around, and the bottom of the well also made a clicking sound, and the remaining well water disappeared almost instantly, and all fell into the black hole generated after the bottom of the well spread.

By the time Shi Lei rose to the wellhead, there was no water in the well at all, but the place where Shi Lei pulled out the bricks began to pour water into it continuously, and the whole process was completely opposite to when Shi Lei was underwater just now.

Shi Lei's secret path is dangerous, although there are no offensive or defensive mechanisms here, but if it weren't for Shi Lei's preparations, when the bottom of the well was opened just now, he would definitely be taken directly to the bottom of the deeper well by the remaining water in the well.

Shining down with a strong flashlight, Shi Lei still couldn't see the bottom, the black rumbling, the water gushing out from the missing part of the bricks couldn't fill the abyss like a bottomless pit at all.

Shi Lei returned to the edge of the well, he was engrossed in watching everything in the well, this mechanism really surprised him a little.

About half an hour has passed, and there is still no essential change in the well, Shi Lei is also a little tired, and he has been lying on the well, even if he is a superman, he can't bear it.

After straightening up, Shi Lei found that the edge of the well had also changed.

The edge of the ground, which was originally intact, appeared as a brick depression at the edge of the ground in the east-facing direction of the well platform.

Shi Lei walked over and saw that the brick had sunk deep into the ground, and he realized that it was possible to operate the mechanism under the well platform by co-authoring.

This brick is connected to the brick down the well.
