"Uncle Chu, I'm waiting for you to come. Let's talk about it together..." Zhang Yu said calmly: "But there is a case, Uncle Chu, you don't know yet... Brother Song, tell me about the case of Xi Tong and Shen Qiu first to Uncle Chu, and then I will continue to say..."

Chu Zhenhuan looked at Song Feng and was secretly surprised. It seemed that this was still a big case.

Song Feng immediately told the case where Chen Qiu was killed and Xi Tong was wrongly imprisoned. Then he emphasized that this case was the first case that Sun Mei took over after Aluo's mute.

After Song Feng finished his talk, he looked at Zhang Yu and said, "Brother, it's time for you to tell me now, what's going on here."

"The real murderer back then is here..." Zhang Yu pointed to Cai Tingdong who was lying on the ground, and continued: "This is how things happened..."

Zhang Yu made how he asked Miao Lan to date Cai Tingdong, and how did he make arrangements after he arrived, and tricked Cai Tingdong into telling the truth about the murder case that year.

In fact, Song Feng has been handling the case for many years and can tell what is going on through suspicion. However, the problem is that Xi Tong has disappeared over time, and it will be even more difficult to find the murderer.

After listening to Zhang Yu's story, Chu Zhenhuan said: "So, Cai Tingdong's case was very likely to have been tampered with Cai Tingdong's grandfather Cai Hongyuan."

"Is it him? It's not clear, but one thing is very important, that is, Cai Tingdong said, he dared not tell anyone about this, but Cai Hongyuan asked him on his own initiative. He couldn't hide it, so he admitted it." Zhang Yu said seriously: "There is a problem here. Cai Hongyuan is just a professor, not a policeman. Besides, the police should not have been so fast at that time, so he determined Cai Tingdong's murderer, and then told Cai Hongyuan the news. So, I think there must be someone who knows the truth here, who will reveal the news to Cai Hongyuan, and Cai Hongyuan does some things and ensure Cai Tingdong's safety."

"Then this person is very likely Mr. Han." Chu Zhenhuan said.

Song Feng nodded and said, "I think so too..."

He then said, "Director Chu, I think you should be able to arrest Cai Hongyuan now and get the trial."

"I have already found out about Cai Hongyuan's residence and asked Qin Yu to arrest people. As soon as he sees someone, he will call me." Chu Zhenhuan said.

Zhendong District, Honor Sanatorium.

In Zhenhai City, people who can live in this nursing home are generally rich and status people.

In the sanatorium, there are all four-story villas and villas, all with amenities, and there are elevators on the four floors. The scenery is good and there is hot spring water, which can be used to recuperate or to liven up your old age. Each villa has 140 square meters, and a nurse is also equipped with a special caregiver.

In Room 209, an old man sat on the lounge chair next to the floor-to-ceiling window in the bedroom. He was closing his eyes and resting. There was also a storytelling in the mp4 next to him. This old man is none other than Cai Hongyuan, a famous professor in Zhenhai City.

With a "click", the door opened and a female nurse in white walked in.

"Mr. Cai, are you asleep?" the female nurse said in a low voice.

"Xiao Wei, what's the matter... Why don't you knock on the door when you come in this time..." Cai Hongyuan closed his eyes and said in a gentle tone.

"Because of some urgent matter, I forgot to knock on the door." said the female nurse.

"What's the matter?" Cai Hongyuan said.

"Someone is coming to catch you soon. The superiors don't want you to see the person alive." The female nurse said calmly.

"What!" Cai Hongyuan, who had originally closed his eyes and enjoyed it very much, opened his eyes directly after hearing this.

He then subconsciously turned his head to look at the nurse and shouted in surprise: "Xiao Wei, what did you say?"

"Although I am a nurse in a sanatorium, I am also a member of the upper class who came to see you just in case..." The female nurse said lightly: "The above suddenly notified that someone came to arrest you, I hope you don't see them..."

"Who is here to capture me?" Cai Hongyuan asked.

"What do you ask so much... I don't know too many things..." The female nurse said calmly: "The above just said that if you don't want to implicate your students, don't want to implicate your grandson, and don't want to implicate other people, then set out as soon as possible..."

"Where to go?" Cai Hongyuan asked.

The female nurse was wearing gloves on both hands. She took out a small bottle from her pocket and walked slowly to Cai Hongyuan's recliner, "The above means that you will know where you go after drinking this..."

"You...you want to kill me..." Cai Hongyuan was a little anxious.

"You should understand that living in this world is not good for many people... It is also for your consideration..." said the female nurse.

"You are killing the donkey..." Cai Hongyuan was excited.

"You can't say that. Your grandson spends a lot of money every month. He doesn't make a penny. Is it enough for him to squander it? Who gave him this money? You know in your heart. If the superiors didn't help him, he might still be in prison now. Don't worry, after you set out, the superiors will definitely take good care of your grandson as before... In fact, it's already very good to let you do it yourself. To be honest, there are several people waiting at the door to come in and feed you medicine... I'm also thinking about your decent old age... Don't hesitate. You have lived at such an old age and have never enjoyed any blessings. You have been glorious and have enough money..." The female nurse said earnestly.

"Hahaha..." Cai Hongyuan smiled bitterly, then reached out to the female nurse, and said sadly: "I, Cai Hongyuan, said with openness and integrity, teach and educate people. I really didn't expect that I would end like this... bring it..."

The female nurse put the medicine bottle into Cai Hongyuan's hand and did not make any sound.

Cai Hongyuan looked at the medicine bottle in his hand, gritted his teeth, unscrewed the medicine bottle, and poured the medicine bottle directly into his mouth.

The female nurse just shook her head gently, then turned around and walked towards the door.

"Lingling...Linglingling..."

Chu Zhenhuan, Zhang Yu and Song Feng were waiting in the living room of the villa.

At this time, Chu Zhenhuan's hand rang. He took it out and saw that it was Qin Yu's phone number, and answered immediately.

"Hey, Qin Yu?"

"Director Chu, it's not good." Qin Yu's anxious voice rang out on the phone.

"What's wrong?" Chu Zhenhuan's heart skipped a beat when he said this.

"We have arrived at the Honor Sanatorium, but when we met Cai Hongyuan, he was already dead..." Qin Yu said.

"Die!" Chu Zhenhuan was startled at first, and then shouted: "How could he die? How did he die?"

"It looks like he committed suicide by taking poison. He was lying on the recliner and there was a medicine bottle on the ground." Qin Yu replied.

"Suicide... impossible..." Chu Zhenhuan said directly: "I don't believe it. He has a clairvoyance and a wind ear... Check it, check it for me..."

"We are investigating, and it turns out that the nurse Li Xiaonan in his room is gone... I suspect that Cai Hongyuan's death may be related to this nurse. Now someone is asking for surveillance to investigate with all their strength..." Qin Yu said.
