Xu Dayuan lit a cigarette and asked the director:

"The Wang family yard and the second floor inside look a bit old. Do you always know when it was built?"

The director pointed to the inside of the yard gate and several people followed him.

"We have a habit here. We have to build our own houses. One is to tie red cloth to sacrifice when the beam is applied, and the other is to carve the year when the house and the yard is built on the stone behind the door.

It’s here that their house built this yard in 1983, and the house was built at that time. The foundation was very deep. It was built by a professional construction team from the city. It was not just a few tiles, and the courtyard wall was taller than ordinary people, and it was three meters tall."

Zhou Ning didn't listen much. This was of no help to the survey. After saying hello to Xu Dayuan, he entered the second floor of Wang Hongzhan's house. As soon as he came in, he saw Yang Xuetong coming down with a box.

“Not found?”

Xuetong Yang shook his head.

"There are four bedrooms upstairs, and the eastmost bedroom has traces of previous investigation. I asked the local investigator. This is the room where the deceased He Dongmei lived. The quilts and clothes placed inside are all summer. There are two trolley boxes on the ground, which are filled with diapers and milk powder and changing clothes. The cabinets are useless.

As for other rooms, whether the furniture or the bed, they were covered with old bed sheets. It seemed that no one lived in them all year round. We checked around and moved the furniture away. We didn’t find any hidden safes or wall mezzanines. The boxes and cabinets were basically empty.”

Zhou Ning frowned. In fact, when he took over this case, Zhou Ning felt familiar because there was a similar case in the books provided by the system before.

It was also a woman who was killed at home with her child and drowned in a water tank. When the police found out, the child's little feet floated on the water. Even the text description was shocking.

The woman is the same as He Dongmei. She is a rural teacher. The child who was hiding a gold bar at home was seen by a child who was tutored. A child went to steal and was discovered by a woman in the middle of the night. Then the woman was killed and the child was silenced.

Zhou Ning was once affected by the case and thought about it in this direction, but the scenes of the two cases were clearly different. People who came in from the north window of the kitchen would definitely leave traces. After all, the window was narrow and thick grease, but the two deceased were clean and had no residue.

After climbing over the wall, it was also denied. The wall of this courtyard is as high as three meters, and it is impossible to come over with bare hands. With the help of tools, rice and flour have to leave traces on the broken glass on the wall, which will make the sound very loud. Now the only way left is the gate.

Zhou Ning then looked at Yang Xuetong and said:

"Ask Bai Hua and Captain Zhang, did they break into the door when they arrived at the scene? Is the lock retained? In addition, are there traces or substances of the keys left on the keys, and have the fingerprints and DNA collected on them?"

Yang Xuetong's eyes lit up and he nodded and ran away quickly.

Zhou Ning then walked towards the room on the west side. As soon as he came in, he saw Da Zhao kneeling on the ground with his butt sticking out. Zhu Xingxing was holding a strong flashlight for him, and he didn't know what to look for in the corner.

"Have you found anything?"

Da Zhao suddenly raised his head, and the back of his head directly touched the top of the cabinet. With a bang, Zhou Ning felt pain when he heard it.

"Be careful, is it okay?"

Da Zhao crawled out from under the cabinet, pulled off his gloves and rubbed the back of his head, and complained to Zhu Xingxing:

"If Zhou Xiaozhou comes, you won't tell me, I'll be scared!"

Zhu Xingxing raised his leg and kicked it, staring and shouting:

"Mr. Ji asked me how big I am. I said I would climb in and see, you have to watch it yourself, and kowtowed me and then beg me."

Zhou Ning didn't participate in the daily life of the two of them. He coughed and approached, and then realized that the part where Da Zhao crawled in was a cabinet similar to a chest of drawers, but it was extremely long, and there were all this cabinet on one wall.

There was an incense burner and several plates on it. I identified that what seemed to be fruits and steamed buns, but it had been completely dried and some things like charcoal that turned black.

With a slight shaking with his hand, Zhou Ning discovered the problem. The cabinet seemed to be embedded on the wall.

“Is there something behind the cabinet?”

When Da Zhao heard this, he was a little discouraged.

"I've checked it and found nothing special. This cabinet is full of drawers. I took out the drawers, but there was nothing inside. But the wall behind it was knocked, and the sound was hollow."

Zhou Ning squatted down and observed carefully. Sure enough, there was a wall behind the cabinet, but he could not see any hidden small door or moving bricks.

Zhou Ning waved his hand and signaled Da Zhao to get up, exit from the room, and observed that the wall inlaid with the cabinet was adjacent to the living room where he entered.

There is a small room side by side on the north side, which looks like a storage room, but there is nothing inside, and the area is only thirteen or fourteen square meters.

Zhou Ning stretched out his hand towards Da Zhao and said:

"Give me a tape measure."

Zhu Xingxing found the tape measure and sent it to Zhou Ning. Da Zhao struggled to get up from the ground and kept slapping the dust on his body. After all, it has not been occupied here for a long time, and the dust is quite thick.

Zhou Ning measured the distance between the things in the storage room, and then measured the distance between the things in the room where Da Zhao and the others were. Seeing the value, Zhou Ning didn't say anything, Da Zhao came over.

"What's wrong? What's the problem?"

"The distance between the two rooms is different, but from the outside, there is no difference in width between the two rooms."

Da Zhao widened his little eyes and rushed directly to Zhou Ning.

"It's a little different, but this is possible. After all, how much difference is the house built in the village?"

"Twenty-two centimeters."

"So many, is there a mezzanine on the walls of this room?"

Zhou Ning didn't say anything, turned around and came to the living room. On the other side of the wall, there were four bookcases of the same height and size placed side by side, full of books. Zhou Ning probably read it. These are not novels, but they seem to be textbooks from Wang Hongzhan since he was a child.

The arrangement is quite neatly. From elementary school to graduate school, the upper part of the bookcase is transparent glass and the lower part is wooden door. You can feel that the material of this bookcase is quite good and has been very old.

Zhou Ning walked over and opened the cabinets on and off the bookcase. Only then did he find that all the bookcases were books on top, and only a few rolls of paper were placed below.

Da Zhao changed his gloves, opened the paper roll and looked at it. There were various awards inside, each of which was separated by a newspaper. The newspaper was a bit old.

Obviously, this was not done by Wang Hongzhan and He Dongmei. It can be seen that Wang's parents were very concerned about Wang Hongzhan's education. They found nothing in several scrolls. Da Zhao quickly restored the things and put them in the room and kicked them.

Zhou Ning stood in front of the bookcase, and it was obvious that there was something wrong with this wall.

He squatted down, looked at the cabinet partition below, reached out to take it off, Da Zhao came over, held up a strong flashlight, and carefully illuminated the corner inside the cabinet.

When I checked the fourth bookcase, Zhou Ning had not touched the partition, but saw two wooden strips on the edge of the wooden plank behind. The wooden strips were light-colored and had a few black dots on it, just across the edge of the back plate. When the strong light flashlight was shining, I found a gap on the edge of the back plate.

Zhou Ning was so excited that Da Zhao wanted to reach out to grab the partition, but Zhou Ning stopped him.

"Don't rush Zhu Xingxing to call Lao Yang and the others over. Da Zhao extracts fingerprints for this partition, as well as wooden strips and back plates, collects samples, especially wooden strips, and sprays luminol reagent. There are black spots on the wooden strips, which I suspect are blood stains."

Da Zhao was energetic and pulled Zhou Ning to one side. He looked at the ground. There were no footprints compared to the surroundings. The dust on the ground here was a little thinner, and the boundaries were clear, which was the traces left by rubbing.

Da Zhao took a photo, then put a survey pad and knelt directly on it. The brush brushed across the partition, and the traces left by two thumbs appeared on both sides. Obviously, this was the action of grabbing the partition, so there were naturally other finger marks below, and Da Zhao lay directly on the ground.

There was no problem with the judgment, and there were fingerprints left below. However, what disappointed Da Zhao was that the fingerprints were fingerprints of latex gloves and did not leave fingerprints, but this discovery had already made Da Zhao excited.

Holding the lumino, spray it carefully on the fingerprint. In the middle of the fingerprint, there was a fluorescent area in the shape of the origin. Da Zhao removed the partition.

Yang Xuetong and the others were already running over. Seeing Da Zhao's posture, Yang Xuetong quickly knelt down and approached. Sun High-speed Railway placed the partition on the physical evidence bag on one side.

Big Zhao sprayed lumino reagent on the small wooden strips. Sure enough, the two black spots that Zhou Ning pointed out were bloodstains. Big Zhao looked back at Zhou Ning.

"I'm opening!"

"Hurry up and stop talking."

Before Zhou Ning could speak, Zhu Xingxing couldn't help but yelled first.

Yang Xuetong held back his laughter. He and Da Zhao each grabbed a small wooden strip and twisted it slightly. As the barrier of the wooden strips removed, the partition behind them bounced directly towards the outside.

Da Zhao quickly took the back plate and exposed the things behind him. Yang Xuetong was so shocked that he opened his mouth wide. Zhou Ning couldn't see it from the angle, and he was a little anxious.

"What's behind? Is the wall hollow?"

Da Zhao handed the back plate to Zhu Xingxing, and then he allowed the position of the survey pad.

"The wall is inlaid with an old-fashioned safe. I don't know if it's been disrepair. One side has collapsed. It's probably because of this that I made a hollow sound when I was hitting the other side."

He quickly collected various information from the safe, found blood stains and a few glove prints, and looked at a pair of password locks and keyholes. He was in trouble.

"We can collect fingerprints on the safe, but who can open this thing? And it's in such an old style. I think it's a tough thing to find a lock unlocker?"

Da Zhao waved his hand, looked indifferent, and kicked Yang Xuetong's shoes.

"Get up, I have a way."

Yang Xuetong quickly moved aside, Da Zhao took a step back and kicked to the upper left corner of the safe. With this action, the originally raised side fell down, and the safe tilted forward, Da Zhao grinned.

"There's nothing that can't be done with a flying kick. If it doesn't work, then another kick!"
