The young police officer's eyes lit up. "Then I'll go to their house and see what's going on."

The middle-aged police officer said, "I'll go with you." This was the most important matter for them right now, and the middle-aged police officer was also a little anxious. He said to Song Yunyu, "Could you please help look after Chen Liuzi's family? After we get the certificate from Chen Liuzi's family, we'll find a way to send them to the hospital."

Song Yun nodded. "No problem. I'm a military doctor. Just let me know if you need my help."

When the middle-aged policeman heard that she was a military doctor, his face showed joy, "Then could you please come with us to collect evidence." Since it was related to poisoning, it would naturally be better to have a doctor.

Village chief Chen's head began to sweat. He winked at his nephew standing in the corner, but unfortunately his nephew didn't even look at him.

It’s not that his nephew is blind, it’s just that this matter is too scary. Village Chief Chen is now a suspect. Anyone who dares to make eyes at him will not dare to talk to him, even if they are his own nephew.

Song Yun agreed readily. There were many people at the health station now, including Uncle Xu and Brother Dang. In addition, the police were also here, so no one would dare to do anything.

Song Yun suggested that Village Chief Chen be tied up first to avoid any further complications.

Before the middle-aged policeman could say anything, the young policeman had already taken out handcuffs and handcuffed him. He also instructed the two men from the Xu family and six young men from Xiaba Village to keep an eye on the man and not let Village Chief Chen escape or let anyone harm Chen Liuzi's family.

The middle-aged police officer opened his mouth and then closed it. "Okay, this is fine, even though it's against the rules." But at this point, being too strict with the rules would put them in a passive position. This might also be their chance to make a contribution.

Led by a young man from Xiaba Village, Song Yun and two police officers entered Xiaba Village with flashlights and came to the most dilapidated adobe house in the village.

"Chen Liuzi's family lives here. They are the poorest family in our village. A while ago, their two elders fell ill one after another, dragging the family down. Life was never this difficult for them before."

The middle-aged policeman nodded, stretched out his hand and pushed open the door which was already half-closed. After entering the room, he originally thought that he would see a mess on the floor, but he found that the room seemed to have been cleaned. Apart from the bloodstains and oil stains on the floor, there was no residue at all. Even the table was wiped clean.

This is obviously not normal.

Who would be so kind as to help Chen Liuzi's family clean the house so cleanly? If there is such a kind-hearted person, why didn't he go to the health station to visit Chen Liuzi's family?

"Do you know who cleaned it?" the middle-aged policeman asked the young man from Xiaba Village.

The young man thought for a moment and slapped his head, "It was the village chief. The village chief asked his wife to clean up. Many people saw it and praised the villagers for their kindness."

Song Yun sneered, walked through the main room and headed towards the backyard.

This type of house usually has front and back yards.

The backyard was not very big. There were two large vats outside the kitchen next to the straw shed. Song Yun walked directly to the vats, opened the lids and shone the flashlight in them. Sure enough, the water in the vats had been scooped out, and both vats were empty.

The middle-aged policeman's face was so dark that it couldn't be described.

This was too obvious. It was obvious that someone had deliberately cleaned up the scene and destroyed all the strong evidence, which further proved the strangeness of the matter.

Song Yun put her head into the jar and sniffed, and sure enough, she smelled a strange odor. She then shone a flashlight at the bottom of the jar and found a trace of liquid remaining.

"Find something to put it in. There's a little water in here."

The two policemen became excited again and immediately started looking for something. Finally, they found a small glass bottle and poured the remaining water in the jar into it.

After collecting the samples, the three continued to wander around the yard and house with flashlights.

Song Yun found a wooden box under the bed in the room where Chen Liuzi and his wife lived.

The wooden box under the bed would accumulate dust and be dirty.

But although this wooden box is old, it is very clean and there is no dust at all. It is obviously a frequently used box.

But how could a box that is often used be placed under a dirty bed?

Song Yun opened the box and saw what was inside. She was so shocked that she almost dropped her jaw and immediately called two police officers.
