Su Le and Liang Fu returned to the Haizhou City Police Station and immediately asked technicians to analyze the surveillance video taken from the bar. The pixels of the surveillance camera equipment in the bar were not high, and the bar was relatively dark, so the video footage obtained was not too bright.

It is so clear that it is difficult to distinguish the writing on the Ruhuan phone screen.

Technicians use AI intelligent blur image processing technology to enhance the contrast of the original lower-quality video, lossless amplification, add sharpening filters and defogging, so that the original blurred video can be upgraded to high-definition level. Then through partial

Zooming in allows people to clearly see the content on the screen when Ruhuan is using the phone.

Ruhuan took out her mobile phone from her pocket and browsed the contents of WeChat first. There were many small red dots in the WeChat chat history. She just glanced at a few pinned messages, then closed WeChat and opened QQ on her mobile phone.

Ruhuan clicked on a QQ account with the nickname bh283519, and the content of their previous contacts appeared on the screen.

Female Ghost: The second amount of money has been remitted.

bh283519: Received.

Female ghost: Then do it quickly, don’t wait and see.

bh283519: Don’t worry, I will never let you down.

Female Ghost: When will it be completed?

bh283519: The task will definitely be completed within a week.

Female ghost: I have already prepared the money for the rest, just waiting for you.

bh283519:Okay.

Ruhuan picked up the wine glass, took a sip of wine, and started a new chat.

Female ghost: How's it going? Is there any progress? Did you take the money and run away?

bh283519: Yes, the woman has been handed over to our brothers in Zhongjiang. As for the man, I have already mastered his work schedule, life patterns and preferences.

Female ghost: What's the use? What I want is the result.

bh283519: He is currently on a business trip to Zhongjiang, and I have followed him to Zhongjiang.

Female ghost: Oh, he went to Zhongjiang?

bh283519: Yes, it arrived yesterday.

Female ghost: What is he doing in Zhongjiang?

bh283519: I don’t know about that.

Female ghost: Then kill him quickly.

bh283519: I have prepared everything. If everything goes well, it will be completed tomorrow.

Female Ghost: Waiting for your good news.

After chatting here, Duan Ruhuan closed the QQ program and started browsing a short video software.

When Su Le and Liang Fu saw this, they exchanged glances and Liang Fu said.

"Can these chat records provide solid evidence that Duan Ruhuan paid the murderer?"

"It's probably not possible. At least we have to find her mobile phone and get all her chat history." Su Le said.

"What does the second money mentioned above mean?"

"It literally means the second payment. It seems that there was another payment before."

"Yes, so is one thing divided into two payments? Or is it two things?"

"They said there would be payment later. It seems they mean payment after completing the task."

"They didn't mention their names during the conversation. Does the woman refer to Duan Rumeng?"

"The man from Gecko replied that the girl should be left to Zhongjiang's brother, at least it's possible that it's Duan Rumeng."

"Who could that man be?"

"I don't know. When the He team arrives tomorrow morning, we will report it and see if Duan Ruhuan can be arrested immediately to prevent the situation from deteriorating further," Su Le said.

Haizhou City Police Station Conference Room.

"Hahaha, it's better to hear than to see. Zhongjiang's beautiful criminal police captain is really amazing. She solved an incredible poisoning and murder case before she even got off the train. It's really admirable." Tang Yinghua, captain of the Haizhou City Criminal Police Detachment, has no doubts.

Stingyly, he extended his thumb to He Xiaohui.

"Wherever, wherever, this is all the work of Dr. Qiao." He Xiaohui pointed at Dr. Qiao and said.

"Oh, Dr. Qiao Zeyuqiao, a physical evidence expert from Jiangnan Province, whom I have admired for a long time."

"Haha, Captain Tang's case-solving deeds are being promoted and studied across the country." Dr. Qiao said politely.

"Captain Tang, we still need your strong assistance when we come to Haizhou this time." He Xiaohui said.

"That's no problem. If you need anything, just say it. We will fully support you in terms of personnel and materials. I have arranged Liang Fu as your liaison. If you need anything, just order her to do it."

"Okay, when we arrested Zhong Hongcai, we found two mobile phones on him and we urgently need technicians to crack them."

"No problem, Liang Fu will arrange it right away."

"Yes." Liang Fu replied.

"In addition, we will soon conduct a surprise interrogation of Zhong Hongcai to thoroughly understand the reasons why he killed Huang Kangcheng."

"Okay, you can start working quickly. If you have any needs, you can contact Liang Fu or me."

After He Xiaohui contacted the Haizhou City Police Department, he immediately rushed to the hotel where Duan Rumeng and the others were staying. Duan Rumeng and the others were currently resting in the hotel, and it was not yet determined when they would go to see Duan Ruhuan. The matter of interrogating Zhong Hongcai was

It was handed over to Deng Ru and Ding Yiran.

"Name?" Deng Ru asked.

"Zhong Hongcai."

"Place of origin?"

"A native of Haizhou, Shannan Province."

"Do you know why I arrested you?"

"I don't know, comrade policeman, I didn't do anything."

"Do you know Huang Kangcheng?"

"Ah, I don't know him. I don't know Huang Kangcheng." Zhong Hong started to get nervous.

"Okay, stop beating around the bush with us and tell the truth about how you murdered Huang Kangcheng."

"No, I didn't kill anyone."

"It seems that you won't shed tears until you see the coffin. If so, let's show him the video we obtained at Zhongjiang Railway Station."

Ding Yiran played the video on the computer in the interrogation room of Zhong Hongcai following Huang Kangcheng at Zhongjiang Railway Station and switching green tea bottles on the escalator. In the face of the ironclad facts, Zhong Hongcai had to lower his head.

"How's it going? We caught you right, right? Tell me, why did you want to kill Huang Kangcheng?" Deng Ru asked.

Zhong Hongcai lowered his head and thought for a while, then raised his head and said:

"I don't know Huang Kangcheng. Someone asked me to kill him."

"Who told you to kill Huang Kangcheng?"

"I do not recognize."

"How did you get in touch?"

Zhong Hongcai lowered his head and said nothing.

"How much will you get for killing Huang Kangcheng?"

Zhong Hongcai lowered his head and said nothing.

"How do you pay?"

Zhong Hongcai lowered his head and said nothing.

"Zhong Hongcai, I believe you also understand our policy, which is leniency for those who confess but harshness for those who refuse. If you can cooperate with our interrogation work, you may not be sentenced to death."

"Officer, there are some things I really can't say."

"Since you are unwilling to talk about this, then tell me about the murder of Huang Kangcheng."

Zhong Hongcai raised his head and looked at the confident Deng Ru and said:

"I followed Huang Kangcheng for several days, following him from Haizhou to Zhongjiang. I found that he only drank one brand of green tea drink, so I prepared a bottle of poisonous green tea and found an opportunity to drop the bag at Zhongjiang Station."

"How did you prepare the poisonous drink?"

"I used a syringe to poke a small hole in the mouth of the bottle. After injecting the poison, I blocked the mouth with a red-hot ear-picking hairpin."

"What poison did you use?"

"Potassium cyanide."

"Where did the poison come from?"

Zhong Hongcai lowered his head and said nothing.

"Do you have any other accomplices?"
