When Mu Zi arrived at the company, some employees had already left work, and the employees who worked overtime did not leave. They ordered a takeaway box lunch and were having a great time.

When everyone saw Mu Zi coming, they put down their lunch boxes to say hello.

"I'm fine, you can eat." Mu Zi smiled and went straight to the president's office.

As usual, she checked recent company statements and some contract data to understand the operation.

After reading these things, more than an hour has passed.

Wang Zhan asked her with concern: "Would you like to order something to eat?"

Mu Zi hadn't eaten dinner yet, she touched her stomach, she was indeed a little hungry, but now Bai Wei must have prepared dinner and waited for her to go home. If she ordered a takeaway, she would be too disappointed to Bai Wei.

"Go home." Mu Zi stretched his arms and stood up.

When she was about to leave, she saw that the technical department was still lit, and she couldn't help but wonder: "Aren't they going home?"

Wang Zhan complained: "These technical nerds are also playing computers when they go back. How can the company have a faster internet speed at home? Of course they all depend on it, and they can save electricity bills."

Mu Zi walked in and took a look. The technician inside seemed to be aware of it, switching screens quickly, and the game screen instantly turned into a working interface!

Mu Zi couldn't help but laughed, and said with a smile: "Don't hide, it's already off work, it's okay to have fun."

It happened to be the technician who helped her check the courier number last time.

"Hello, President." The technician smiled wryly.

Mu Zi walked over, saw a floor plan displayed on his computer, and asked, "What is this? It's also the company's business?"

"Yes, help a rich woman to catch a junior." The technician's smile revealed a bit of a narrow, "This business seems inconspicuous, but it is actually very marketable, and it is one of our company's main income."

Mu Zi was a little curious. He tilted his head and looked at the floor plan carefully—it should be an apartment, with the floors and elevator locations marked, and some data she couldn't understand.

The technician explained to her: "This apartment has a total of 32 floors. We collected surveillance video from the entrance and in the elevator. Based on the video time and the walking time of the characters, the computer calculated the destination and found out that the man was supporting him. What room does the woman live in."

"So amazing?" Mu Zi was surprised.

The technician smiled triumphantly: "The power of technology."

Mu Zi thoughtfully asked him: "If there is no surveillance video, but there is a confession to provide time and content, can I use a computer to calculate the result?"

"Yes, use cross-validation!" The technician replied decisively, tapping his thigh.

Mu Zi raised his eyebrows, "Cross-validation?"

"Cross-validation is a statistical method." The technician was afraid that Mu Zi could not understand it, and used the most simple way to illustrate, "For example, the president sees me working overtime in the company, and Manager Wang and the president are together, so we can conclude Conclusion: Manager Wang can prove that I worked overtime in the company."

Mu Zi thought carefully, but did not speak for a long while.

"You can work overtime tonight," she said suddenly.

The technician was confused and nodded blankly, "Hey, good president."

Mu Zi returned to the office and logged in to her own web disk, which contained the information Jiang Ci gave her.

Not only is there a list of everyone on the yacht on the day of the incident, but also everyone's confession, as well as the yacht's structural drawings.

More than 30 people, the testimony is true and false, and some guests even said that they had drunk, do not remember, not clear.

It is too difficult to filter out the real murderer, but if there is such a computer technology...even if the murderer cannot be locked, at least the suspect can be quickly screened out, right?

Mu Zi erased the names of each person, replaced each person's name with English ABC, and then gave it to the technician for analysis.

The results came out very quickly.

"Here, it's F." The technician pointed to the person's name and said, "At 9:17 in the evening, only he might have been to the bow."
