This topic is too sensitive and they didn't mention it again.

Even so, the third uncle's face was always dark and he showed a vague hostility towards them.

They bypassed the cafeteria and went to the sanitary building where the patient lived. The five-story house was charred and all the items in the building were burned. Each room was left with empty iron cabinets and several broken metal bed frames.

"The first thing happened was the fire in this room." Uncle San pointed it to them, "When we found out, we went to find Dad Hu immediately because there was a radio speaker in the guard room, which could wake up the researchers and nurses, and then we all put out the fire together..."

There is an open-air aisle more than ten meters between the sanitation building and the experimental building. The top of the aisle was originally a whole piece of rainproof glass, but now it is empty, and some glass fragments can be vaguely seen in the dust on the ground.

The third uncle took them to the laboratory building.

"When we saved the patients, the first and second floors of the experimental building caught fire at the same time, and there were explosions... But there were only seven or eight of us, so we couldn't save both ends. There were so many patients in the sanitation building..."

The third uncle seemed to remember the tragic situation at that time, sighed again, waved his hand and said, "You can watch it here, I'll wait for you outside."

Chen Yan said thank you.

As soon as the other party left, Chen Yan put away a polite smile on his face, turned to look at Lu Weiwei and Sister Mei: "No matter whether they are villagers or not, the fire must be no accident."

Sister Mei was puzzled: "What is the purpose of setting fire? Just venting anger?"

"That depends on the results of the fire." Lu Weiwei analyzed calmly, "First, almost no patients in the sanitation building survived; Second, all the data and data in the experimental building were destroyed. The purpose of the arsonist would be to kill or destroy."

"There is a greater possibility of destroying information." Sister Mei said, "The fire protection facilities in the experimental building are complete, and there are researchers on duty every night. If the fire suddenly catches, it will be extinguished soon. If I am a person who sets the fire, I will choose a care building. After all, there are so many patients there, and most of them have lost their ability to take care of themselves, which gives me an opportunity to take advantage of it."

Lu Weiwei nodded after hearing this, "Yes, it's very time-consuming to rescue so many severely ill patients from the firehouse scene. Moreover, the fire time is four or five in the morning. There are not enough people involved in the firefighting, and the firetruck cannot be rushed in a short time... This person who sets the fire is very delicate."

"Listen to what you said... I feel more and more that the person who sets the fire is a woman." Chen Yan said coldly, "Women are so scary."

Lu Wei bent her eyes slightly, "Forensic Chen is not afraid of death, are she still afraid of women?"

Chen Yan: "I'm not afraid of dead women."

"Stop being poor. He just said that the second and first floors are on fire. We have not been to the second floor yet." Sister Mei led the way in front and "Go up and take a look."

The three of them went to the second floor as they spoke—

As soon as I went up the second floor, a depressed and gloomy breath came to my face. Even the temperature seemed to be a few degrees lower. The whole environment was both dim and wet, with spider webs and sticky wet moss in the corners of the wall.

Several narrow light shone in from the top, reflecting pale white on the mottled and black floor.

"The difference between upstairs and downstairs is so big..." Chen Yan murmured, looking up, "I only have a vent on the top, and there is not even a window."

"Why do you need to design this way?" Sister Mei couldn't help but frown. The moldy smell here made her get goosebumps.

The deer gently stroked the wall, and the touch was thick and hard. Without any design, it was just a wall.

Chen Yan pushed open a metal door, and the creaking sound seemed particularly harsh.

The room in front of me is similar to the layout downstairs, the only difference is that there are no windows. This kind of enclosure makes Chen Yan murmured, could it be that Lu Qinglin had done an illegal experiment here?
