"It's simple."

"Simple?"

"You do a little experiment and you'll see what's going on."

"What test?"

"Smash a bone with a heavy object a few times, and then apply sulfuric acid to the traces, and all the traces will be eliminated, and it won't be long before the smell of sulfuric acid will evaporate."

"The traces were corroded away by sulfuric acid. So that's what happened. ”

This is the end of the conversation, and the Hosvens have nothing to do with Cha Rengui's death.

After that, with the assistance of Gao Jianguo, Liu Dayu spent one day investigating and visiting 24 people (9 men and 15 women) provided by Wu Dawei, and none of them were suspected of committing crimes except for their relatively close age. There are also some discrepancies between the physiognomy and the simulated portraits of these people. It can be seen that the opinions given by the computer can only be used as a reference.

The trip to Shanghai ended in disappointment.

At about twelve o'clock that night, Liu Dayu and his entourage returned to Jingnan.

Ouyang Ping had to take the second move, originally, Ouyang Ping had already thought about the second move, and after contacting Che Rengui's wife, Ouyang Ping was quite surprised: The Che Huating brothers had a lot of whispers about their father, Che Huamei was full of complaints about his father - and even some hatred, Che Rengui's wife's attitude was even more treacherous, did Che Rengui's death have anything to do with the people in the Che family compound? If you want to figure out this problem, you can only find the old man who used to work in the Chejia compound to understand the situation.

Ouyang Ping decided to start the investigation with Jin Cuiping and Lou Asi first, and Director Gu promised to guide everyone - he also felt that Che Rengui's death might be the problem with the Che family, but he never said what he thought. As for the fact that he mentioned the matter of the Chejia compound on the first day of contact with his comrades, it was completely idle talk.

Jin Cuiping's family and Lou A's four families are all in the Confucius Temple, one is in Zhaojuren Lane in the south of the Confucius Temple, and the other is on Zhanyuan Road in the west of the Father and Son Temple.

Director Gu led everyone to Jin Cuiping's house first.

Jin Cuiping's family lives in the innermost part of Zhao Juren Lane, by a small river, with three low-rise houses built against the courtyard wall. The house was enclosed in a low, dilapidated wall.

The courtyard gate was tilted very much.

Director Gu slowly pushed open the courtyard door.

At the door of the room sat an elderly man with reading glasses perched on the bridge of her nose and patched trousers.

"She's Jin Cuiping." Director Gu whispered to Ouyang Ping as he walked to the old man's side.

The old man looked at it for a moment, and finally recognized Director Gu: "Isn't this Director Gu?" ”

"Auntie, you are so old, and your eyes are so good!" Director Gu pressed the eldest mother's arm with his right hand - the eldest lady lowered her head and bent down to stand up.

"No—no, look—I can't even do needlework. Director Gu, what is the matter with you—you're here? ”

"Aunt Jin, we are here for the case of No. 157."

"How? Is the case of No. 157 eyebrow-raising? ”

"The identity of the deceased, we have figured it out."

"Who is the deceased?"

"The deceased is Cha Rengui, who has been 'running away from home' for five years."

Jin Cuiping was silent for a long time, and then said in a shocking voice: "What? Cha Rengui? That's right. Jin Cuiping was first inexplicably surprised, and then looked calm.

"Old man, can you make this clearer?"
