My plan is very clear and simple. The entrance to the yelling spring is inside the earth building. According to general logic, the entrance must be underground in the earth building. There are people coming and going on the hall on the first floor of the earth building. I have never thought about that direction, so I have never noticed that there is any special entrance or strange place on the first floor.

The most important person tonight is Jia Hezi. There are too many noises during the day. When it is late at night, Jia Hezi should be able to hear the sounds underground.

However, the area of ​​the Tulou is really beyond my imagination. Unlike Tingnu, Jia Kezi's hearing is not possible to directly hear all the underground situations in one location. Therefore, we must divide all areas on the first floor of the Tulou, and then listen in different areas, and collect information from several locations to infer the basic situation in the underground.

I divided the first floor of the Tulou into 12 areas. The first floor is mainly the staff dormitories, warehouses, and kitchens. These areas are usually locked, and many areas cannot enter, which is very troublesome. I need a reason to let Jia Kezi enter all areas tonight. I have already figured out this reason. I need a power accident, and I cannot disturb other floors. The power accidents in all rooms on the first floor need to be controllable.

At this time, I was no longer afraid of being recognized because I was very clear that the information on the fourth floor would not be transmitted to the fifth floor, and even if the people on the fifth floor knew that I was coming, with Xiaohua's confidence, he would not pay attention to me.

Fatty and I went down to the first floor and started to line up all the wires. Fatty said to me while lined up: "There are so many people in this rescue activity. If we were to do it in the public area on the first floor, would you think the people on the first floor would not notice it? There were at least hundreds of people on the fifth floor. We had not monitored the entire building at night and had no large-scale activities."

The fat man said it a bit exaggeratedly, but I think it makes sense. No matter what, the entrance must lead to the underground. I need to reverse the situation underground.

To put it short, we used Xiangdun technology to cut wires on the first floor that night. Jia Kezi's feedback proved my idea. There are many spaces underground in the entire earthen building. The relationship between these spaces was not heard, but it was confirmed that about three spaces could accommodate more than ten people. The most valuable thing was that Jia Kezi heard that there was a hidden staircase in the earthen building.

This staircase leads to the fifth floor. And Jia Huizi heard the clear sound of people moving, and someone went directly to the underground from the fifth floor.

I sighed and said, "Xiaohua didn't have to go downstairs at all. They had hidden stairs that could directly enter the underground."

The staircase was not straight up and down, but was moving up and down the earth building like a snake. It was probably not a real staircase, but a secret passage made in the earth building's organization. Jia Hezi heard many parts, and the sound of people walking was very strange, not the pace of the stairs, but the sound of stepping on nails on the wall.

I couldn't go up the fifth floor and go in from the entrance of Xiaohua, but on the floor where we lived, our room was very far from this passage.

The most bizarre thing is that the passage is on the third floor, the second floor, and the first floor, and the sound is very weak, so we cannot determine the direction of the passage on the third floor, the second floor, the first floor, but on the fourth floor, Jia Kezi heard a clear direction.

We kept guarding until dawn and determined the room closest to the fourth floor and the passage. I went back to the room for 15 minutes. After getting up, I went straight to the next step. I had to go to the fourth floor, enter that room, and from that room, without anyone discovering it, enter the secret passage, and then enter the shouting spring.

I asked Bai Haotian to go directly to the fourth floor to see who was living in the room. After Bai Haotian came back, he pointed directly at the young man with copper coins on the wall, "It's him."
Chapter completed!
