"Drama actor." Han Bin muttered.

Han Bin's micro-expression analysis method is entry-level, with advanced and expert levels on it.

The micro-expression analysis method is to judge a person's true feelings and emotions through subtle expressions and body movements on the face.

The entry-level micro-expression analysis method can only be distinguished by body movements.

Advanced and expert micro-expression analysis methods are used to judge a person's emotions through subtle expressions on the face.

"Micro-expression" can last at least 1/25 seconds. It is an instinctive expression and will not be controlled by human thinking. It is very difficult to accurately capture it.

Being an actor means learning to control emotions, put yourself into that role, and putting your emotions into what you think.

Han Bin's micro-expression analysis method is only introductory. If Tang Yu's acting skills are good enough, he may have deceived him, and Tang Yu's transcripts will not be credible.

The information of Tang Yu, Xiang Hongbo and Luo Xinghua were displayed on the projector one after another, and Luo Xinghua's address was also recorded in detail.

"Dingling..." Zeng Ping's cell phone rang.

Zeng Ping got up and went to answer the phone.

When he returned again, Zeng Ping smiled: "WeChat company has come to the news. They checked He Shirui's payment records. They spent it at Jinsha Bar at around 10 o'clock the night before yesterday, with an amount of 48 yuan."

It's time to file a case!

...

There are many office buildings around the cafe. In order to cater to the taste of the white-collar class, the cafe's decoration is mainly white and elegant, with a bit of a petty bourgeois mood.

Two men and one woman were sitting on the inside against the wall, among which one was Tang Yu and Xiang Hongbo. The man opposite looked like he was in his twenties wearing black-framed glasses.

"Hongbo, the Tiaozi didn't find me." asked the man with black-framed glasses.

"No." said Xiang Hongbo.

"That's good." The man with black-framed glasses breathed a sigh of relief.

Luo Xinghua said, leaning over and picking up a travel bag from below and putting it on the coffee table.

"Tang Tang, you have a lot of contact with the police, so you should talk about it." Xiang Hongbo said.

Tang Yu nodded and described his contact with the police yesterday.

While Luo Xinghua listened, he occasionally asked a few questions. The three of them chatted for half an hour before leaving the cafe.

The three of them left the cafe, and a man followed him out. The man was not old and wore a baseball cap. It was Han Bin's informant Chen San.

He touched his chin and muttered, "What is the travel bag in his pocket?"

...

After Zeng Ping reported the progress of the case to Zheng Kaixuan, Zheng Kaixuan formally applied to the branch for investigation.

At this time, Zhao Ming sent the communication records to Hong Bo and the other two to the WeChat group.

WeChat company also cooperated very well and sent the chat records of Hongbo and the other two.

Zeng Ping walked into the office with the printed documents: "The mobile phone communication records and WeChat chat records are here, let's see what their relationship is."

"yes."

The four people used different contact information, and it was quite messy to sort it out. Han Bin mentioned it to organize it according to the timeline.

It took Han Bin and others half an hour to figure out the clue.

"Dadada..." A series of footsteps sounded, and Zheng Kaixuan walked into the office.

"Capital Zheng, has the application for filing a case been approved?" Zeng Ping asked.

"Although no fatal injuries were found on the deceased, based on WeChat payment records and bartender's testimony, it is enough to confirm that this is not a simple accidental death. The branch has approved the investigation."

"It's great, it can be considered an explanation to the family of the deceased." Tian Li said.

"Don't be too happy too early. If the case is filed but the murderer cannot be caught, it is your responsibility." Zheng Kaixuan warned.

"Captain Zheng is right. The filing of a case is just the beginning of success. Our real challenge is still to come." Zeng Ping echoed.

Zheng Kaixuan pulled a chair and sat down: "Is there any new progress in the case now?"

Zeng Ping nodded: "Han Bin, tell me."

"We have transferred the contact information of He Shirui, Tang Yu, Xiang Hongbo and Luo Xinghua. After comparison, we found some abnormalities." Han Bin held the carbon pen in his right hand, turned it a few times and then said:

"Before He Shirui's death, Luo Xinghua contacted Xiang Hongbo and He Shirui very frequently, but after He Shirui died, Luo Xinghua rarely contacted Xiang Hongbo again. Even if he contacted him, he just made a phone call and never used WeChat again."

"What is the relationship between these four people?" Zheng Kaixuan asked.

"Luo Xinghua and Xiang Hongbo are friends, and Xiang Hongbo and Tang Yu are lovers. Luo Xinghua is pursuing He Shirui, so he is willing to help her pay a high room fee."

"Has the pursuit been successful?"

"It probably hasn't been there yet." Han Bin said.

"Does Luo Xinghua have anything to do with He Shirui's death?"

"Before He Shirui died, Xiang Hongbo knew that Mao Yiran had come to Qin Island and told Luo Xinghua about this. This made Luo Xinghua angry and nervous, and even wanted to find someone to deal with Mao Yiran." Han Bin said.

"How did Xiang Hongbo know that Mao Yiran came to Qin Island?" Li Hui asked.

"I think it was Tang Yu who lied." Han Bin squatted on the table with a pen:

"He Shirui should have told her about Mao Yiran's visit to Qindao, and might have even discussed it with her. Tang Yu told her boyfriend about it again, and sent a WeChat message to Hongbo to tell Luo Xinghua."

Zheng Kaixuan touched his chin and thought for a moment: "Where was Luo Xinghua on the day He Shirui died?"

"From the chat records between Luo Xinghua and Xiang Hongbo, Mao's resolute arrival put a lot of pressure on him. In order to pursue He Shirui, Luo Xinghua planned to spend a lot of money to rent a yacht to take He Shirui out to play. The appointment was at 8 pm on August 24th." Han Bin said.

"He Shirui's death is from 8:00 to 10:00 pm, which means that He Shirui is likely to die on a yacht." Zheng Kaixuan guessed.

"He Shirui can't swim. After falling into the water, she wanted to catch the yacht and save herself, so paint debris remained at the cracks of her nails. This forensic Wu's conclusion is consistent." Zeng Ping analyzed.

Zheng Kaixuan nodded: "I finally found out some of my eyebrows."

"Dingling..."

A cell phone ringing rang, and Zeng Ping walked to the side to answer the phone.

After a moment, Zeng Ping frowned and walked back:
Chapter completed!
