Mo Xiaoqing's hands were shaking with excitement. She opened her phone and continued to check for another clue, which was the diary taken from Teacher Chen's home.

Now she seemed to be assisted by God. Her mind was very clear and she stared at the screen of her phone carefully.

"When I went out today, it was snowing outside. There

was no sun and no snow.

There was a cold chill and I felt the chill.

I was wrong for forgetting to put on more clothes. The fault

was that the damn weather forecast was inaccurate.

Shouldn't it be sunny when the Spring Festival is approaching?

These girls who want to be graceful are bare-legged.

There is no air conditioning outside the door. Don't they know? They

are all fools who think this is fashionable and beautiful

. It is the capital of revolution, as the saying goes.

Did you go out without your brain? Unexpectedly, the pig-headed boyfriend next to her said:

Baby, you are so beautiful like this.

Ah, they are all fools.

Suddenly, she found an exciting clue. This diary seems to be venting dissatisfaction with the cold weather and women's clothing, but it is actually another kind of venting.

Just looking at the first word of each line, Mo Xiaoqing read it one by one, and it turned out to be a complete sentence.

"I'm not wrong, what's wrong is that they are full of treasures."

Mo Xiaoqing remembered that when she sneaked into Chen Xiaoshi's study, the papers scattered on the ground were all white papers with "I'm not wrong" written on them.

It was obvious that the room was messed up by his own irritable mood.

Why did he go crazy?

Chen Xiaoshi also lives in the urban village of Dongjing Street, not far from the twins' home, and is very familiar with the twins. He may also be in a deformed relationship with the twins in private.

The murderer of the homeless man is related to the moon-shaped thing, and Chen Xiaoshi's family has a moon-shaped nameplate.

Chen Xiaoshi has uremia, and dialysis requires expensive fees, and his account always has a large amount of money shortly after the murder.

Is it possible that

Chen Xiaoshi is the murderer of those homeless people, and he has been secretly engaged in black market organ trading for a long time.

After killing people, he takes out the organs and sells them, earning a lot of money. The twin sister Xiang Xinfang accidentally saw something, and Chen Xiaoshi was afraid that the matter would be exposed, so he planned to kill them.

Coincidentally, the twin sisters were abducted by the madman Deng Yaohua, and escaped after being raped. They ran to Chen Xiaoshi's house, originally wanting to ask for help from their teacher and lover whom they had always trusted, but they never thought that they would lose their lives instead?

Mo Xiaoqing pieced all the events together, and all the inferences could be connected very smoothly.

She shouted excitedly, "I know, it must be like this, I know everything."

She was happily dancing in the office alone, and was seen by Xu Yao who just stepped in.

Xu Yao's eyes were dull as he asked, "What good news makes you so excited?"

Mo Xiaoqing was struggling with her thoughts in her mind. With the clues she had currently, she should be able to report her final results to Team Xu.

She took a deep breath and strode to Captain Xu to report, "Captain Xu, I have something very important to report to you."

"Okay, then go ahead."

Mo Xiaoqing bit her lower lip, her face flushed, and finally mustered up the courage to whisper, "Captain Xu, I beg to go to your office and report to you alone."

Xu Yao looked at the little one's rosy face and couldn't help but joke again, "Why? You want to confess to me but you're embarrassed. Okay, then come to my office!"

Mo Xiaoqing was so anxious that she jumped up and down, and said angrily, "I don't want to confess, I'm talking about business."

She followed him all the way into Captain Xu's office, and before he even sat down, she shouted loudly:

"Captain Xu, I know who the murderer is. Who really killed the twin sisters!"

Xu Yao's eyes widened, with a look of surprise on his face, "Oh? Tell me about it."

"It was Chen Xiaoshi, the high school teacher of the twins." Mo Xiaoqing said in a firm tone.

Xu Yao waved his hand, motioning her to continue.

Mo Xiaoqing said slowly:

After my secret investigation during this period of time, I got very conclusive evidence to prove that Chen Xiaoshi must be the murderer.

Captain Xu, I don't know if you still remember that I had a cold and fever a few days ago, and you asked me to go to the city center hospital for an IV drip.

I met Chen Xiaoshi outside the medicine window at that time, and greeted him, but he looked nervous, and a prescription fell out of his belt.

I didn't notice it at the time, but my roommate Juanzi found it. It was a prescription for treating uremia.

In fact, I had already become suspicious at that time. Later, I asked Chen Xiaoshi's attending physician and found out that Chen Xiaoshi had already suffered from uremia four years ago.

Uremia patients can only get more effective treatment through kidney transplantation, but kidney transplantation is also an expensive expense.

I heard from the attending physician that he had given up kidney transplantation because his family had no money, but later he called and said that he had collected the money.

I carefully inquired about the time point and found that it was exactly the same as the time when the first homeless man was killed in 2014.

Captain Xu, you mentioned that there were four murders of homeless people in Kuala Kangsar, where their organs disappeared. The murderer has never been caught, but a moon-shaped pattern was left.

Coincidentally, I saw a moon-shaped badge in Chen Xiaoshi's study.

I also asked Liu Xiaobo to check Chen Xiaoshi's account. There were several huge amounts of money in his account. The most recent one was the day after the twins Xiang Xinyi were killed. Chen Xiaoshi's account suddenly had an extra NT$600,000 of unknown origin.

I am very sure that he is related to the murder of the homeless man and is the murderer of the twins.

Mo Xiaoqing said a lot to herself, while Xu Yao sat on a solid wooden chair, leaning against the back of the chair, smoking one cigarette after another, and the air was filled with smoke.

Suddenly, he sat up and flicked the ash, "Oh, are you sure that Chen Xiaoshi is the murderer based on just these few pieces of evidence?

There are only three motives for murder: love, revenge, and money. Why did Chen Xiaoshi kill the twin sisters? And I remember that Chen Xiaoshi seemed to have an alibi at the time."

"Captain Xu, this is not my guess. In fact, I also thought that Chen Xiaoshi had no motive to kill his students, until I asked a classmate of mine to find the twins' microblog account.

There are many photos of the sisters in it, and I copied all the information. Captain Xu, do you want me to show it to you?"

Xu Yao stood up and gave her the chair.

Mo Xiaoqing deftly took out the USB drive from her pocket and inserted it into the computer. The screen appeared quickly, and she casually clicked it to show Xu Yao.

"Captain Xu, you see, these twins are not as well-behaved as they look on the surface. They not only smoke and hang out in nightclubs in private, but also..."

Mo Xiaoqing was embarrassed to continue. She looked at the photos of those with dog collars hanging on the sides of their necks, wearing tight leather jackets and leather pants, and holding whips in their hands, and her face suddenly turned red. She

realized that Captain Xu was only one foot away from her, and his even breathing could be felt on Mo Xiaoqing's face.

A man and a woman were alone in the same room, and they were looking at these photos of beautiful women in revealing clothes together. Mo Xiaoqing felt shy for no reason when she saw the coy look in the photos.
