Mercury iodide is an acute poison and has no taste, so it was hidden from the police.
If they hadn't discovered it in time, Qi Yunhai would have died.
Qi Yunhai turned away, "If you don't believe me when I tell the truth, there's nothing I can do about it."
Seeing that Qi Yunhai's mouth could not be pried open, Lu Yao sneered, "I admire your selfless dedication."
Qi Yunhai said calmly, "Comrade Lu Yao, I advise you not to waste your efforts. I told you yesterday that no one instigated me. I just didn't want to wait for you to retaliate against me, so I decided to strike first. You must If you want to bring innocent people in, you must have evidence."
Lu Yao narrowed her eyes.
Qi Yunhai looked at the police, "Do you have anything else to ask? If not, I'm going to rest."
Seeing him like this, the police couldn't continue to interrogate him. Nowadays, it is most taboo to torture him to confess.
Lu Yao followed several police officers out.
"Uncle policeman, have you found out who Qi Yunhai has met recently?"
"No suspicious person has been found yet, but please rest assured that we will continue to investigate and will never let any bad guy go unpunished."
Lu Yao: "Thank you."
The policeman waved his hand and said, "You're welcome. This is our duty. But recently, you still have to be careful. This family is quite ruthless and they might attack you again."
Lu Yao: "Didn't you ask Qi Yunhai's mother?"
"We asked. The old lady is old. As soon as we told her that her son was being rescued in the hospital, she fainted on the spot."
Lu Yao frowned. At this time, a young policeman hurried over with a heavy expression, "Captain, Qi Yunhai's mother committed suicide."
Hearing this, everyone was shocked.
"How are you now?"
"It was out of breath when we found it."
The captain exhaled heavily, "Did you tell me anything before you die?"
"She said her son had suffered all his life, and she didn't want her son to continue to suffer in prison, so she bought medicine to poison her son and give him a happy life."
Lu Yao took a deep breath.
This old lady had to defend Wang Caizhi before she died.
What bargaining chip does Wang Caizhi have in her hand that makes Qi Yunhai and her son willing to commit suicide to protect her?
The police went to the scene, and Lu Yao stood on the road, looking confused.
"Duan Mingjie, I can't figure it out."
Duan Mingjie didn't understand either.
"Qi Yunhai has been in prison for more than ten years, and his mother has been waiting for more than ten years. How could she be willing to poison her own child? Isn't she trying her best to make him live a better life?"
Duan Mingjie pondered for a while, "Let's go back and ask uncle. He might be able to find out something."
The two returned to Dong's house. Lu Yao told Dong Defang the matter, "Uncle, send a few people to find out who Qi Yunhai's mother met yesterday."
"It's been checked out."
Hearing this, Lu Yao and Duan Mingjie were both startled.
Dong Defang said in a calm voice, "I have two friends whose relatives live in the same village as Qi Yunhai. I went to find them after you left, and they asked about my relative Qi Yunhai's family."
Lu Yao: "What did they say?"
"According to their description, Qi Yunhai has been in prison for so many years, and his mother has not had a hard time. A few years ago, they built two brick houses."
Lu Yao's brows became tighter and tighter.
“Doesn’t anyone in their village doubt where the money to build the house came from?”
"Of course there are suspicions, but Qi Yunhai's mother is fierce and has killed people with the help of her son. People in the village are afraid of them. Even if they have suspicions, no one dares to ask more questions."
"But that's not the point. The point is that yesterday, a woman secretly found Qi Yunhai's mother. According to their description, it was Wang Caizhi."
Although he was sneaky, he was still seen.
Knowing the news, Dong Defang was furious.
He never thought that Yaoyao's guess would be confirmed.
Whenever he thought that Wang Caizhi was responsible for his eldest sister's death, Dong Fangguo wanted to cut Wang Caizhi into pieces with a thousand knives.
Lu Yao bit her lip and said, "Uncle, I don't understand. If mother and son are here for wealth, nothing will be lost after death. No matter how much money Wang Caizhi gives them, it will be useless. Also, I can't figure it out. Qi Yunhai's mother actually poisoned her own son for Wang Caizhi, don't you think it's outrageous?"
Tiger poison does not eat seeds, let alone humans?
Dong Defang: "Don't worry. Now that we have a breakthrough, the next thing will not be difficult. I will let people go over to investigate."
There are some forces in the Dong family that were not exposed openly. They did not investigate carefully back then because they were afraid of alarming the capital. Now that he has new targets and clues, he will never let his eldest sister die in vain.
Lu Yao was not in a hurry, she was just thinking about what to do next.
Lu Yao swept her jaw with the tip of her tongue, "Uncle, I think Wang Caizhi may have something that Qi Yunhai, mother and son, want to protect. They may not be protecting Wang Caizhi, but the chips in Wang Caizhi's hands."
This bargaining chip must be something more important than their lives.
"What could it be?"
Duan Mingjie: "People? Children?"
Hearing this, Lu Yao and the others looked at Duan Mingjie.
Lu Yao, "You mean, child?"
Duan Mingjie just guessed, but after telling him, he found that the possibility was extremely high.
"As you said, if they are doing it for money, then one of them, mother and son, must live to enjoy it, right? Otherwise, it will be meaningless no matter how much money Wang Caizhi gives them."
"Qi Yunhai's mother wanted to poison Qi Yunhai and then commit suicide. She died without any evidence. Even if the matter is over, no matter who investigates, there will be no results."
"In this life, people either do it for their own enjoyment or for future generations."
Lu Yao frowned, "Did Wang Caizhi kidnap Qi Yunhai's child?"
Lu Yao suddenly realized a question, "Does Qi Yunhai have children?"
Lu Yao's words reminded Dong Defang and Chen Yuncai.
Chen Yuncai and Dong Defang glanced at each other, and the latter said loudly, "I don't remember Qi Yunhai has a child?"
Duan Mingjie: "Qi Yunhai doesn't have a wife?"
Dong Guofang shook his head, but he was a little unsure, "It seems that he is not married."
"Does Qi Yunhai have any brothers or nephews?"
"No, I paid attention to the situation of his family when the eldest sister left. Qi Yunhai originally had two brothers, but they starved to death during the famine, so he was the only son of his mother."
Lu Yao's brain was running rapidly. Many things seemed to be connected together, but it seemed that something was missing and couldn't be connected together.
"Uncle, now Qi Yunhai's mother is dead and Qi Yunhai is still in the hospital. There must be everything in his village. Let's go over and take a look now. We will definitely find out what we want!"
Dong Defang thought for a while and said, "Okay, wait a moment and I'll make a call."
