As Shi Tianliang spoke, he could not hold back his tears: "My son Dalei's death was really unjust, but we are just ordinary people. The police said he was beaten to death by a wild beast, and we have no way to do anything."

Zhou Shixun looked at Shi Tianliang expressionlessly. Although he didn't know what exactly had happened, he knew that the body discovered by Zhou Luancheng and Mu Xiaowan was the son of this seemingly honest man in front of him.

At the same time, he also knew that he had recognized the wrong person and mistook himself for Zhou Luancheng.

Shi Tianliang always felt that Comrade Zhou, who came the day before yesterday, had changed a little. He became colder and harder, and seemed to be less talkative.

Thinking that Zhou Luancheng had seen through her, she cried even more sadly: "I have pity on you, an old man. I didn't have three sons to keep, and in the end I have to send off my son. You are a police officer from Beijing, can you redress the injustice for this poor old man?"

Zhou Shixun's nose moved, and he keenly caught a strange smell in the air. He had smelled this smell at the border. It was a fragrance that could make people faint.

There is also a smell of potassium nitrate in the middle.

The scent of the drug was very faint, not enough to make him unconscious, but it just showed that Shi Tianliang had used these things before.

There was still a faint fragrance on his body. As for potassium nitrate... it was an ingredient that could be used to make explosives. What did he do with it?

Since he mistook him for Zhou Luancheng and knew Zhou Luancheng's identity, it meant that Shi Tianliang and Zhou Luancheng had come into contact and had some understanding of each other.

So were Zhou Luancheng and Mu Xiaowan both harmed by Shi Tianliang?

Although Zhou Shixun was dull and not good at speaking, he was quite smart and quick-witted. He looked at Shi Tianliang crying calmly.

After a while, Shi Tianliang's wife Li Xiumei came in with swollen eyes. When she saw Zhou Shixun, she mistook him for Zhou Luancheng and felt somewhat resentful.

He was more out of anger than venting his anger on others. He couldn't find the murderer who killed his son, and he had to accept that his son was attacked by a wild beast.

She didn't understand why Shi Tianliang did this, she just felt sorry for her only son who couldn't come back. She pointed at Zhou Shixun and cursed: "It's you. You must know who killed my son, and then you reported it more than ten days later. You pretended to be innocent. You must be avenging that vixen!"

Shi Tianliang stood up and pushed Li Xiumei: "What are you talking about! How can Comrade Zhou be that kind of person? We can only beg Comrade Zhou to redress Da Lei's injustice."

Li Xiumei wanted to yell, but Shi Tianliang stopped her with a look. She held all the words in her stomach and didn't dare to say a single word.

Shi Tianliang turned around and apologized to Zhou Shixun helplessly: "I'm so sorry for making you laugh at me. My son is gone, and my son is a little mentally ill. We two old people have pity on us..."

As he spoke, he wiped the tears from the corners of his eyes.

Zhou Shixun then spoke calmly: "Since you already have suspicions, go to the police station and report the case. After all, the murder case is under the jurisdiction of the jurisdiction where it occurred."

Shi Tianliang was stunned for a moment. Since Zhou Shixun came in, he also felt that his voice had changed a little. Before, he had a Beijing accent and his tone was very flat.

And now, what he said had a slight Ganbei accent and his voice was deep.

Then I thought I might have overthought, or I didn't pay attention that day. How could there be such similar people in the world? "Comrade Zhou, are you not used to our climate? It's colder here than in Beijing, and the wind and sand are stronger."

Zhou Shixun hummed and didn't explain further.

Shi Tianliang felt that Zhou Luancheng seemed to be much easier to talk to today, so he quickly asked tentatively, "You said just now that you were here to look for someone? Who are you looking for? How about I help you find someone? It's getting late. If you don't mind that my family just had a funeral, you can stay at my house."

Zhou Shixun was also very direct: "It's the girl who was traveling with me."

Shi Tianliang was surprised: "Are you talking about Mu Xiaowan? Didn't she leave with you? Did something happen?"

Zhou Shixun didn't know whether Zhou Luancheng and Mu Xiaowan were together now, so he could only make up an excuse: "He disappeared after we separated in the town."

Shi Tianliang sighed: "Did she go back to Beijing first? You came here, you can't be suspecting that someone in our Shijia Village hid Mu Xiaowan? That's absolutely impossible. This girl was an educated youth in our village. She is a smart girl and we all like her very much."

Zhou Shixun's eyes fell on Shi Tianliang's palm when he was waving his hand. The calluses on the base of the palm and the thumb and index finger were quite thick, but there were no calluses on the palm.

He withdrew his gaze before Shi Tianliang noticed, lowered his eyes and pondered secretly.

As farmers, people in this area depend on the weather for their livelihood. Life was quite hard in the past few years, and calluses on the hands are a normal sign of people making a living.

But Shi Tianliang, who is nearly sixty years old, has no calluses on his hands. Instead, there are calluses on the base of his thumb and index finger. This is very abnormal.

Plus there was a faint smell of potassium nitrate on Shi Tianliang's body.

Let Zhou Shixun confirm one thing: Shi Tianliang usually plays with guns and makes his own ammunition.

What does he do these things for?

Suddenly he asked, "When I came here, I saw a river beside the village, but there was no water in the river. Is it because there was not enough rain this year?"

Shi Tianliang was a little confused, not understanding why he suddenly asked this question. Did he discover something? After thinking for a while, he answered with a vigilant look: "It is indeed a drought this year. The crops have been harvested less. I don't know how to survive the winter today."

Then he started to complain: "Although we are less than 200 kilometers away from Beijing, the conditions are really tough. There are yellow mountains all year round, and we have to rely on the weather for food. This year we are in such a dry season, it's difficult. So I thought of letting my son and his uncle go out to see if they can do something to make a living."

"As the old saying goes, if you move a tree, it will die, but if you move a person, it will live. I just wanted to find a way around it, but who knew it would turn out like this? If I had known, I would not have let them go out even if I starved to death at home."

Zhou Shixun looked at Shi Tianliang crying sadly with no expression.

When he came, he had noticed that the grass and trees by the river were lush and the red willows on the riverbed were unusually plump and strong, indicating that there had been plenty of rain this year.

He grew up in the village and is very clear about these things.

There are also crops in the fields, which are obviously grown very carelessly. They are just food to fill their stomachs, the food that the farmers take the most careful care of, but their village manages them very casually.

This means that the village has other sources of income, and it is not from formal channels.

Zhou Shixun suddenly stood up and said, "I thought about it and realized that the girl I was traveling with might still be nearby. Could you please mobilize all the villagers to help me find her?"
