The room was dark because there was no light on and the windows were closed.

Chu Hongqing, who was lying on the bed, heard someone coming in. He sat up and turned on the light at the head of the bed.

"Uncle."

Chushhan called.

"Ah Yan is back?" Chu Hongqing rubbed his temple and said feebly, "I'm sleepy, but I can't sleep. As soon as I close my eyes, I feel flustered. I don't know what's going on."

Chu Hongzhong stepped aside and poured him a cup of warm water.

When he finished, he said in a low voice, "I still have to ask Xiao Sheng to come and have a look."

Chu Hongzhong didn't believe this before, but since he met Lu Sheng, he began to believe it.

"Uncle, where have you been lately?"

Chushhan pulled a chair and sat down at the head of the bed.

Chu Hongqing shook his head: "I didn't go anywhere. I went to some places I often go."

"Have you ever eaten anything special?" Chusihan thought for a moment, then asked.

"What's special..."

Chu Hongqing frowned and fell into thinking. After a long time, he said, "if you've ever eaten something special, it's a kind of medicinal wine that an old classmate brought back from the countryside. Drinking it can relieve fatigue."

He had just finished talking with a client and was feeling a little tired. When he saw the old classmate pour it for him, he drank it.

Chusihan nodded and asked, "did everyone else drink?"

"It was just me and the old classmate, but he drank it too."

"Ah Yan, do you suspect that there is something wrong with the wine?"

Seeing that his son kept asking, Chu Hongzhong also guessed something.

Chu Sihan nodded, looked at Chu Hongqing and asked, "uncle, do you often contact that old classmate?"

"I haven't seen it for ten years." Chu Hongqing said: "I had just met a client and was ready to go home, but I saw him downstairs. When I was at school, I was in the same dormitory and had a good relationship with him. Therefore, he invited me to a nearby restaurant for dinner, so I should go."

"What about the wine?" Chu Hongzhong asked.

Chu Hongqing also noticed that it was not right. He quickly replied, "he said that he had just come back from visiting his mother in the countryside. His mother asked him to bring the wine. He intended to drink it himself, but when he met me and saw that I looked tired, he offered to pour me half a bowl."

Chu Hongzhong frowned, "why does he appear in the company downstairs?"

"He opened Didi. He said that he was sending the client to the neighborhood. He was about to leave, but he met me."

Chusihan sneered, "how can there be so many coincidences in this world?"

He looked at Chu Hongqing and said, "uncle, do you know where your old classmate lives?"

"I don't know." Chu Hongqing shook his head. "He just left me a phone call."

Chusihan said, "you said that he had drunk the wine at that time, so call to ask if he had any problems."

Chu Hongqing nodded, took the mobile phone and found the number to broadcast.

The phone rings a few times and the customer service prompts that they are on the phone.

Chu Hongqing called again. This time, he turned it off directly.

"It's off!"

Because he turned on hands-free, Chu Sihan and Chu Hongzhong heard it.

Chu Hongzhong said in a deep voice: "there must be something wrong with you old classmate!"

"But he used to be a very honest man, and I have no grievance against him. Why did he harm me?" Chu Hongqing couldn't figure it out.

After all, he and the old classmate haven't seen each other for ten years. He won't hurt him at the first sight, will he?

Chu Hongzhong said in a light voice: "people are separated from each other. What's more, you haven't seen it in ten years."
