Opening this kind of door lock was not difficult for Mo Xiaoqing. In less than half a minute, the door opened.

After Mo Xiaoqing stumbled in, she closed the door and quickly searched for clues in the room. Teacher Chen's furniture was relatively old, and the room looked a bit messy, but not sloppy. There were more than

a dozen kinds of medicines piled on the coffee table in the living room. Mo Xiaoqing picked up a bottle of medicine and took a look. It was indeed used to treat uremia.

Mo Xiaoqing remembered that the last time she went to investigate Teacher Chen, he was bowing and doing his best to tutor students. He should have been sick at that time. Such a good and responsible teacher actually suspected that he was related to the murder case. Mo Xiaoqing felt a little guilty.

Work schedules were posted on the surrounding walls, and the days marked in red on the calendar were all related to teaching.

"Fifth monthly exam", "Midterm exam", "Mathematical Olympiad", "Essay writing competition".

There were various trophies and certificates on the bookcase. From these honors, we can see that Teacher Chen's competence is definitely not in vain. He must have silently paid a lot behind the scenes.

Mo Xiaoqing carefully checked the medicine list on the coffee table and took photos for preservation. She searched the living room several times, but there were no useful clues.

She had to go to the bedroom to continue searching, but she didn't expect that the bed sheets in Teacher Chen's house were actually red roses.

In the cabinet at the bottom of the bedside table, she found a braid, a dog chain, handcuffs and other items, and they seemed familiar.

Mo Xiaoqing quickly took a photo.

Suddenly, he found something in the gap of the bedside cabinet. He squatted down and stretched out his hand to touch it hard. He took it out and found that it was a transparent glass bottle with English letters written on it.

"Sixth Aunt, I brought you your favorite octopus balls when I bought vegetables. Eat them while they are hot."

Teacher Chen's voice came from outside. Mo Xiaoqing panicked and quickly put the glass bottle in her pocket and ran to the door as fast as she could.

Fortunately, someone was pulling the rope hanging clothes outside. While Teacher Chen and Liu Po ​​were chatting, she slipped out without anyone noticing and hid at the side of the house.

After Teacher Chen entered the house, Mo Xiaoqing slipped out the door from behind the orange tree.

Walking on the road, she was still in shock. She took out her mobile phone to look at the photos and the props in the bedside table. Suddenly, she remembered that these props had appeared in the photos of the twins.

Mo Xiaoqing quickly left the village in the city. While sitting on the bus, she took out the photos in the twins' trumpet. After careful comparison, these props were surprisingly similar. It is very likely that they were in Teacher Chen's bedroom.

In this way, Teacher Chen really had an improper relationship with the twins. But the last time I talked to Teacher Chen, he deliberately concealed this fact.

But why did he hide these?

Just like Captain Xu said, no possible suspect can be let go. In this case, Teacher Chen may also be related to the death of the twins.

After the twins were killed, their bodies were dismembered. Except for the heads and organs, all other parts were placed in plastic bags and thrown out.

The murderer hid the heads of the deceased, possibly to conceal the identities of the deceased, but for what purpose did

he hide the organs? If the people were really killed by Deng Yaohua, Mo Xiaoqing saw in the room where animals were dissected that every time Deng Yaohua dismembered an animal, the animal organs were thrown all over the floor. He should not have the habit of collecting internal organs.

The police searched every corner of Deng Yaohua's residence, almost digging three feet into the ground, but still did not find any organs of the deceased.

Mo Xiaoqing vaguely felt that Teacher Chen must be related to the two murders. If she wanted to solve this mystery, she had to continue to investigate in depth.

The first thing she thought of was the hospital where she ran into Teacher Chen getting medicine.

After leaving Teacher Chen's house, she rushed to the hospital without stopping. Since it was the weekend, the hospital was crowded.

Mo Xiaoqing had no choice but to start the investigation during the lunch break.

She showed her police ID to show her identity as a criminal police officer, and soon found out from the nurse who was the attending physician of Teacher Chen Xiaoshi.

After being led to the attending physician's office by the nurse, Mo Xiaoqing stretched out her hand to greet the doctor and began to get down to business.

"Hello, Doctor Liu. Sorry to disturb your lunch break."

"No problem. It is also our responsibility as citizens to cooperate with your police work. Officer Mo, please ask!"

Mo Xiaoqing went straight to the point and started asking questions concisely:

Doctor Liu, when was Chen Xiaoshi diagnosed with uremia?

Doctor Liu turned on the computer, typed on the keyboard to find relevant information, and replied: "The first time he came to the hospital for a check-up after he became ill was in March 2013. When he came to the hospital, his condition was not too serious. At that time, I warned him not to work too hard, but he said that the students he taught were all going to enter university, and he couldn't abandon them.

I believe Officer Mo should have heard of the disease called uremia. It comes with great force and is an incurable disease. Once you have it, it will cost a lot of money. If it is found that timely kidney surgery can delay the time of death, there is a high probability of getting a new life."

Mo Xiaoqing asked, then didn't Teacher Chen choose a kidney transplant?

"I mentioned it to him at that time, and he said he would think about it. He also talked to me about the financial issue at that time. For a kidney transplant plus subsequent treatment, an average family would have to prepare at least 500,000.

I remember that a day later, he called me and made it clear that he wanted to give up the kidney transplant, saying that he could not afford the surgery fee."

Doctor Liu took a sip of water and suddenly remembered something, "But three months later, Teacher Chen suddenly changed his mind and said he wanted to do a kidney transplant."

When Mo Xiaoqing heard this, she thought that Teacher Chen should have found a way to raise enough money for the procedure.

She looked through the medical records that Dr. Liu handed to her about Mr. Chen. It said that he did not undergo a kidney transplant.

Mo Xiaoqing was confused and asked Dr. Liu, "Why didn't he undergo the operation in the end?"

Dr. Liu was a little flustered and spoke hesitantly, "I'm not sure about this. You have to ask him for the specific reason."

"So how has Mr. Chen's condition been in recent years?"

Doctor Liu spread his hands and said: He now relies on dialysis to live. If he lives a regular life and is not under too much pressure, he can live for more than ten years. But there are also cases where he can't hold on for 3 to 5 years.

Listening to this, Mo Xiaoqing felt very blocked in her heart. Although she didn't have much intersection with Teacher Chen, or in another sense, Teacher Chen only entered the country as a suspect of her.

She didn't want to face this fact. If she continued to investigate, Mo Xiaoqing would feel more guilty.

But in the face of justice, there is no emotion. There are many murderers who have all kinds of tragic stories behind them. From a moral point of view, they are not wrong, but they have committed crimes and should get the punishment they deserve.
