In silence, Zhao Yongqi was led into the hall to sit down. Du Laigui touched the hot water bottle placed on the table, poured out a cup of warm water and placed it in front of Zhao Yongqi. Then he returned to his side and sat down. He looked up at the man who couldn't see his face clearly and said, "Police officer, the criminals have arrested me, I don't know what else?"

Shaking his head slightly, Zhao Yongqi was silent for a moment and said, "The murderer of these four people was indeed captured by killing your parents, Du Youfu and his wife, Wu Xiuniang, and your second brother Du Laihua. However, the murderer of the murderer of Du Laifu and his wife has not been caught."

"..." Du Laigui, with a stiff face, seemed to be able to see the starry eyes behind him, which were as dazzling as stars through the black lenses. However, at this moment, he seemed to have no feeling of appreciation.

With his fingers rhythmically hitting the table, Zhao Yongqi stared at the man in front of him, and finally said, "When I found that there were only four corpses in the valley, I was thinking. Generally speaking, the murderers of consecutive murders will use the same method. The same method of committing crimes, the same method of throwing corpses, etc. Although the damage of these four corpses is not the same, one thing is certain, they are all made of very simple weapons, stones, wooden sticks, etc. So, tell me why the murderer's method of throwing corpses for more than ten years has fewer than the two in the middle?"

"..." Du Laigui continued to remain silent, but his face seemed to be a little stiffer.

It seemed that Du Laigui's abnormality was not seen. Zhao Yongqi continued: "At that time, I was thinking, maybe Du Laifu and his wife were not injured by the same murderer. Then..."

Retracting his gaze, Zhao Yongqi lowered his head and took out a medical record packaged in a certificate bag from his pocket. He still knocked it on the table and said, "Then, I found this medical record book locked in a drawer in Du Laihua's bedroom. It records Du Laihua's condition of infertility when he went to the provincial capital hospital to check for infertility. The answer given by the doctor was 'genetic congenital sterilization'. This is an occasional family disease. In other words, there was a problem with the genes passed down by one of your parents. Combined with your elder brother and second brother, you have not had children for many years. I can draw a conclusion that is - none of you four brothers have fertility!"

"..." Du Laigui, whose eyes widened, moved his lips and wanted to say something, but in the end he shut up and said nothing.

"Since I had this kind of guess, I had another even more terrifying guess." Zhao Yongqi looked up again at the man who had already lowered his head and remained silent in front of him, and said in a deep voice: "Maybe, Du Yue was not Du Laifu's biological child, but a child adopted for some purpose."

Speaking of this, Zhao Yongqi touched a golden monkey wearing red thread in his pocket, placed it gently on the table, and continued to say in a gloomy voice: "The little girl is going to go into the house to get this thing. She told me that this is what you gave her, her mother's relics, so that she can leave a memory. There is really nothing to doubt about this, and I didn't take it seriously at first. However, since I had another idea, this thing has become very important. Your village is not rich. More than ten years ago, I believed that this was not a 'little thing'. If Du Laifu and his wife really love children, it is completely normal to give their daughter. But the problem is, what if it is not their biological child? So I asked my subordinates to take it to the village to ask the old man, and there was no need to inquire too much. Even the village chief's family could easily recognize this thing."

After a moment of silence, Zhao Yongqi spoke again: "The village chief's daughter-in-law tells us that Du Laifu's wife Ma Yuexiu was a woman who likes to show off and show off. This little monkey is not only a token of her, but she never leaves her body when she wears her, but even in winter, she will be exposed outside her clothes and swaying from time to time until... before she disappeared...every day!"

Zhao Yongqi, whose tone became colder, looked at Du Laigui again and said in a deep voice: "Now, can you tell me again, how did you get this thing from a missing person and then give it to Du Yue?"

"..." Du Laigui remained silent, as if he was like a wooden man without saying anything.

After waiting for a while, Zhao Yongqi knocked on the table, thought for a while and said, "After that, I thought of a possibility, that is, the Du Laifu and his wife died in the hands of someone who truly cared for the little girl. This person may have buried the Du Laifu and his wife near the little girl's residence. The reason is very simple, and he felt guilty!"

"So, I took people to dig the house on Xiaoyatou Mountain. Just under the house, there was a 'coffin' made of gravel, and there was a 'cock' made of gravel lying inside. There were two dead bones on one of them. There was a jade pendant with broken ropes on the neck. It was engraved with 'Lai Fu', and the woman wore gold and the man wore jade. This jade pendant must be the token of their confidants." Zhao Yongqi paused a little and said, "Now, please tell me again, why did you, who built the house, not find these two corpses that were not buried deep?"

With a sigh, Du Laigui, who had been silent for a long time, raised his head and looked directly at Zhao Yongqi for the first time, and slowly spoke, "I killed my third brother and third sister-in-law."

Zhao Yongqi, who remained silent, did not force him. He knew very well that Du Laigui would say this and would not hide anything.

As if he had figured out something, Du Laigui seemed to be trapped in the past and said: "My third brother and his third sister-in-law often worked outside the country back that year. That year, when they were almost two years away from home, they suddenly came back and hugged a cute daughter. Our whole family was very happy, even if it was a daughter, it was our real niece. My parents were very happy, and I really like that cute little thing.

However, I soon discovered that my third brother and my third sister-in-law didn't seem to like her very much. At first, I thought it was because of the girl, and even persuaded my third brother by drinking alone. Unfortunately, there was no change. Although I didn't want to do this, this is my third brother's housework after all, and I can't just let it go.

As the days pass by day, the little thing is also taken care of by my parents all day long. But one day, my parents suddenly disappeared. Although my parents said before that my family property would be left to the little thing in the future, there was nothing in black and white. After they suddenly disappeared, the third brother and the others were even more ill-faced and ill-faced!”
