Xu Yi reacted relatively quickly, and when he saw that he had made a mistake, he immediately dodged and jumped away when he saw that the opportunity was wrong, and finally didn't let the dirty water get drenched, but just splashed a piece on the leg of his trousers, which didn't cause much consequences.

However, such a big opening is not at all a basin can be catched, and because when this is poked up, it is stabbed at the middle of the basin, and when it is pulled back, it is broken towards its own side, so more than half of the gap is outside the basin, so except for a small half of the stagnant water falling into the basin, most of the rest falls directly to the ground next to the basin, and a large piece spreads on the ground.

Looking at the dirty water in the place, Xu Yi couldn't help but sigh, this water is difficult to collect, there is a threshold in this room, it is difficult to get out, so I have to wait for myself to take a broom and sweep it up a little bit to dry, or come back next time, I don't know what the tide is like in the house, maybe except for the ones that can't grow hair, all of them will have to be moldy.

Seeing that the water had fallen and there was no obvious water on the plastic sheet, Xu Yi went out with the basin and splashed the water in the yard.

But when Xu Yi returned to the house with the broom and the dustpan to prepare to sweep the water, he couldn't help but be stunned - the water that had just splashed out was obviously a large area, and even a small pool on the ground, but now there is not much left, and even if there is a little left, it can be seen that it is decreasing.

Although it is said that the green bricks can also absorb water, sometimes they sweep the floor at home, if it is too dry, they are afraid that there will be ashes flying up when sweeping the floor, and they will sprinkle a little water on the ground, and then sweep when they are wet, but they have never seen it like this directly like a sponge to suck in, is this green brick also lonely for a long time, hungry and thirsty like this?

After looking closely, Xu Yi found that there was a small hole in the ground with a brick crack on it, and the surrounding ground was a little higher than here, and most of the water gathered at this brick crack and seeped into it along the brick joint.

This is even more strange, this paving of the green brick floor, there is a little sand underground, but that is to flatten the ground below, there is not much, if too much, but because of the continuous stepping on the green bricks, the sand will be pressed to the side, the brick will not be solid, in this house, when I was a child, I didn't bounce less, and I didn't see any bricks being stepped on and sunk. It wouldn't be surprising if it was a glass or two of water poured down and absorbed, but the water leaking on the ground was almost a bucket. Where is this where a little sand can absorb, could it be that there are cracks in the ground under this brick?

Feeling strange, Xu Yi simply went to get a shovel over, reached into the crack of the brick and pried it hard, and directly pried a brick up from the ground, only to find that the sand under the brick was not wet at all, it seemed that the water did not flow in this direction, so Xu Yi in turn stretched the shovel into the pit to pry the brick, against the row of bricks on the opposite side, and wanted to pry down that side to see.

After all, one side had already been pried open, so Xu Yi didn't exert much strength at all, just casually pressed down on the shovel handle.

As a result, I could only hear the tooth-sore click of the shovel against the green brick, but the brick did not move.

Needless to say, there must be something wrong with this brick, Xu Yi took the broom and swept it directly on these bricks, and he didn't feel that there was anything wrong, until he took the shovel and poked it hard into the gap opposite these bricks, only to hear a bang, and the shovel was bounced up as if it had touched an iron plate.

After looking carefully, I found that these bricks were simply connected together and could not be separated, and the neat and slightly sunken brick joints were just a shallow groove less than an inch deep that had been carved out, covered with soil, and the brick joints looked the same.

I used a spade to probe down the edge of the slate, and found that it was half a spade deep, and the slate was not yet at the end, what was such a big stone put here for?

Using a shovel to crack a brick seam and a brick joint, Xu Yi finally found that the stone slab was almost one and a half meters square, and the top was made like a green brick, if it wasn't for this time, he didn't know when he would find it.

There must be a demon when things go wrong, so careful to cover it up must be because there is some secret under this stone. This thing could never have been originally grown on the ground, how could there be such a regular natural stone?

"There must be something wrong here!" Thinking of this, Xu Yi's heart couldn't help but feel hot, feeling that he was about to discover some big secret.

Along the edge of the slate, along the green brick that was pried down just now, the green brick next to this brick was pried down, and I didn't find any difference, after prying almost four or five bricks, when I pry off a brick, Xu Yi suddenly felt a light hand in his hand, and it didn't take much effort to pry the brick off.

Xu Yi didn't care, thinking that this brick was probably not put away when it was inlaid, so when he picked up the brick and put it aside, and was about to pry the next piece, he suddenly found that the stone slab was concave into the edge of the brick that was almost the size of a wine glass, and he could see that there was a raised round button that looked like the size of an egg.

"There's a trap!"

Xu Yi saw it, took a few steps back without hesitation, reached out to take the stick that fell from the ground, took one end to the button, and then retreated to the other end, stretched out his arm and pressed it hard.

I only heard a "click", followed by a "squeak" sound, and I saw that the stone slab was almost one meter square on the slate, and suddenly it was lifted up facing Xu Yi's side, and then it was lifted directly to the opposite side.

Xu Yi secretly screamed, "It's not good, this is a secret door!", and quickly grabbed the basin next to him and blocked it.

As a result, nothing came out of the expected poison gas and arrows, but a hole in the ground one meter square, after that...... There was no after, Xu Yi held the laundry tub and waited there like an ostrich for a long time without any movement.

Xu Yi scratched his head, it seems that he has read too much of this novel and thought too much.

However, this hole also made him feel very strange, and after thinking about it, Xu Yi walked to the edge of the hole of the secret door and looked at the air at the entrance of the cave, which was still transparent and colorless.

Hearing that there was no sound inside, Xu Yi turned around and went to the door of the room, covered the door, retreated to the secret door again, lit the candle again, and reached the hole to stretch inside.

The candle flame only fluttered slightly because of the movement, and then burned quietly in the mouth of the cave.

Seeing that the candle was not extinguished, Xu Yi nodded, it seems that there may be air circulation below that is not likely to be hypoxic, but it is not excluded that because the secret door is opened, the air circulation at the entrance of the cave, carbon dioxide is diluted, if you want to go down, you have to light a candle, after all, the human body's response to hypoxia is not as obvious as the candle flame, and if there is really a lack of oxygen, it may soon lead to suffocation, and it is too late to escape.

I took a careful breath, there was no smell, and I didn't feel anything abnormal.

Everything he could think of was done, Xu Yi took the candle and looked at the top of the secret door, the cyan slate more than a foot thick, it looked quite heavy, and the side facing the cave was slightly smaller than the outside side, so that the four sides of the stone were trapezoidal and shrunk inward, and they were also inlaid with a thin strip of leather three or four centimeters wide, which seemed to be waterproof.

On the ground was a square hole in the shape of a mouth, and there was no sound in it. Through the incandescent lamps on the ceiling and the dim candle flames, you can see that under the hole is a funnel-shaped square hole more than a foot deep, and the upper side of the shaft gradually expands to the surrounding area, and you can see that if the upper cover is lowered, it can be just stuck in this hole, and the wedge-shaped contact surface just makes the lid firmly stuck in the frame and will not shake, and the strip of leather around it can ensure that the dust and sewage on the ground will not seep into the hole. There was not even a trace of sewage on the escalator and the wall of the well, but considering that the edge of the secret door was quite far from the crack, it was thought that the sewage had another place, or maybe this was the gap that was specially designed in the first place, so that the water that had accumulated in the ground could be quickly drained through the gap and flow down the underground channel below to other places, preventing the water from soaking for a long time and penetrating into the wellhead.

But if this is the case, no one can sue Xu Yi, and he doesn't know.

Below the wellhead, there is a vertical shaft about one meter wide, except for the wall that cannot be seen on its own, the other three walls are inlaid with very smooth stone slabs, which looks very solid and smooth. Half a meter below the wall of the manhole cover, there was a very steep wooden staircase, which stretched diagonally towards its side and disappeared outside the hole. There is also a handrail on each of the stone walls next to the left and right walls, and from the reflected luster, it looks like it is wrapped in brass, or people used to go up and down, and the handrails on both sides have been rubbed to the light, and this handrail also extends with the stairs and disappears from view.

It seems that if you want to know more, you have to go down to this stairwell to know, and after checking it carefully, you can see that there is no obvious mechanism ambush on the wall of the well, and Xu Yi is not clear about anything else, so he can only take a risk.

Xu Yi was a little excited and a little scared in his heart, as if he had returned to his childhood when he was alone in those ruins to hunt for treasures.

Back then, I could often find some small bits and pieces such as copper plates among the ruins, and I still have a small wooden box in that warehouse.

But if you want to go down, you have to make more preparations, after thinking about it, Xu Yi ran out of the door, looked in the direction of the dam, and saw that there was no one, so he returned to the house, closed the door completely, and prepared to go down the stairs to take a look.

I don't know what this thing under this Clear Source View is for, and where it leads?
