At this time, the fat man was gripping the corners of Chen Xie's clothes tightly with both hands, his eyes were closed, and his mouth was still chattering from time to time. When I got closer, I found that it was a willow, and the ghost that the fat man saw was its shadow, and the sound was also made by the willow tree. The three of them breathed a sigh of relief, but they didn't dare to stay longer, they always felt that this house was not an ordinary house, and there seemed to be some important secrets in it.

They had already come to the center of the inner courtyard, and the second problem came, there was a well in their east, west, north, and south directions, and when they came to the well, Chen Xie shone the light into the well and found that there was water in it, and the horn and the fat man also checked the other three wells one after another, and there was also water in them. These four wells are all made of large bluestone, and they look very old. Chen Xie squatted down and took a closer look, the upper surface of the wellhead was very smooth, and the texture was no longer clear. Suddenly, the trumpet seems to have found a problem,

"Look, the water levels in these wells are different."

Chen Xie and the fat man checked it carefully, and it was true that there was a difference in the water level in the well, roughly the water level in the east and west was twice as high as the water level in the north and south, and the water level in the east and west and the opposite water level in the north and south were the same. Chen Xie was very puzzled and couldn't find the answer, for the difference in water level is only in physics, the fat man and the trumpet are also caught in the puzzle. The three of them searched near the well and still found no new finds, they came to the third gate, hey, very strange, the door is closed, the door is locked, look closely, the lock has no traces of opening, it is intact, the clue is broken again, if someone comes in and does not go through the back door, where did the person go?

The three of them were confused, all clues were gone, and they tried to find the answer behind the third door, but once again their hopes were dashed.

Chen Xie also began to be anxious and nervous, he took a deep breath to calm himself down, the number was very calm, he returned to the well to look for clues, the fat man was still so afraid to hide behind Chen Xie.

Returning to the well again, everyone's eyes focused on the two wings, first came to the west wing, it was supported by two bluestone pillars, the stone pillars were carved with some flower and bird patterns very exquisite, approached, opened the door, it was very dark inside, and the three of them walked into the room, each walking very slowly, very lightly for fear of alarming something. There is a round table inside, the table is wooden, there are two cups and a pot on the table, both of which are porcelain, the surface is smooth, and there are some flower and bird patterns on it, which looks as if it was from the Qing Dynasty. Go inside, a wooden bed, but the strange thing is that there are no sheets on the bed, look closer, it looks like it was stolen by a tomb robber, there is a dresser next to it, the mirror is a bronze mirror, it is not clear on it, there are many cracks on the mirror, the three of them have been looking around in this room for a long time, they have not found anything, they have also thought about whether there will be a mechanism in the room, but this idea is directly dispelled, there is nothing in the room, their eyes turned to the east wing, hoping to find the answer there.

Walking out of the West Wing, the three of them may be full of more expectations. When I came to the door, the structure outside did not change at all, and when I opened the door, there was a screen inside, and the screen was carved with landscapes, flowers and birds, and human reliefs. Bypassing the screen, all three of them widened their eyes, not knowing what they were seeing. I saw a candle lit on the chess table, and the light was very weak, probably due to the obstruction of the screen, so I didn't notice it. The fat man was already scared stupid, his whole body was twitching, Chen Xie and the trumpet were also very scared, but he still had the courage to walk over, under the light was a table of chess and cards, black and white chess, it didn't seem to be finished, the chess pieces were very messy, and he couldn't see the flaws in them at all, the trumpet thought it was very fun, and wanted to move the chess pieces, but was directly stopped by Chen Xie,

"Trumpet, don't move—"

The trumpet was startled at this time,

"It's better not to move the chess pieces, if you move a chess piece randomly, there may be a mechanism, and no one can escape this fate,"

Chen Xie pointed to the chess pieces and said.

"Phew-you scared me, so let's go inside,"

The horn took a deep breath and walked straight inside.

Chen Xie and the fat man didn't talk much, they followed behind the number, there was nothing similar to the West Wing room, the only difference was that there was no dresser in this room, and the place of the dresser was a table of chess and cards, they searched around again, but still didn't find anything. After that, the eyes of the three of them were focused on this table of chess, and the number was not interested in chess, so he didn't know anything about chess. On the contrary, the fat man usually likes to play chess, although he is not a master of chess, at least he knows a little bit about chess, Chen Xie also knows a lot about chess, but he doesn't know a lot. At this time, the trumpet spoke,

"Fatty, look at your cowardice, come and see how this chess is cracked."

The fat man was pushed over by Chen Xie, and the fat man was very scared,

"I-I-"

The fat man was so anxious that he couldn't speak.

"Fatty, take a deep breath and calm down, relax,"

Chen Xie gently stroked the fat man's back to soothe him.

Ten minutes have passed, the fat man has improved a lot overall, he took a look at the chess and cards, the situation on the chess and cards is obvious, white has a great advantage, black is obviously lagging behind, but the next is black chess, only the last chess is left, how to play to make black turn things around, defeat into victory. Chen Xie thought of many ways to move in his mind, but he still ended in failure, only to see the fat man frowning his eyebrows as he looked at the chess and cards, thinking about it. The horn didn't think much of it, and he looked elsewhere for clues. Time is moving by minute by second, Chen Xie looked at the table below It was already more than four o'clock, looking out, the sky began to gradually brighten, Chen Xie couldn't think of any other way to go, maybe all the hopes were pinned on the fat man, the room was very quiet, the silence was terrible. Maybe it's an illusion, the shadow is about to be,

"Got it, I know how to go,"

The fat man shouted excitedly.

Haozi and Chen Xie quickly came to the fat man's side, very puzzled, and couldn't believe that the fat man had untied the chess.

When I came to the chess and cards, I saw that the fat man picked up the black chess and played it very powerfully, and moved it up two squares, and the chess pieces stayed there and let go of his hand. Suddenly, they all froze there, not speaking, not knowing what was going to happen at this time. Suddenly, in their ears heard,

"Crunch-crunch-"

It sounds like the sound of a chain walking, the direction of the sound comes from outside the door, the three of them ran directly to the door, the scene in front of them surprised them, what is this, only to see two splints in the middle of the road moving to both sides, the rhythm is very fast, soon you will be more surprised, there is a hole in the middle of the road, the three of them came closer to see, there are steps down, the hole is very dark,

"Come and see, why is there no water in the well,"

The trumpet shouted by the well. Chen Xie and the fat man rushed over and found that all the water in the well had been drained, and without thinking too much, they looked at the other three wells one after another, and got the same answer, there was no water in the well.

"What's going on, where did the water in the well go?"

The number is puzzled.

"Maybe there's a hole in the well, and the role of the mechanism won't have anything to do with that chess,"

The fat man bowed his head, unsure.

"I think what the fat man said is very reasonable, there must be a mechanism underground, and the key to this mechanism is the chess,"

Chen Xie pondered.

"It's not like the mechanism is opened, the water in the well flows down the hole, and the water flows upwards through the principle of air pressure in physics, and the splint is pushed away by the strong thrust of the water."

Trumpet explained.

The fat man and Chen Xie both nodded, without refuting, and both agreed with the statement.
