"Kang Qianhui: Oh, yes, I remembered another one. On Monday, I was trying on clothes at the door and heard someone singing a birthday song next door. It should be two people celebrating another person's birthday."

Birthday song? Whose birthday is it?

Xu Qiubai asked Liu Xunyue, and found out that neither her nor Liu Xinyi’s birthdays are in the near future.

Then again, Xiao Liu would celebrate a birthday for someone in school? Unless it was Yingqi, this joke wasn't funny.

But Yingqi’s birthday isn’t coming soon!

Xu Qiubai still remembers his girlfriend's birthday.

Who could that be? ?

"Kang Qianhui: I also found it very strange, but when I listened carefully, the door was closed and I couldn't hear anything."

"Kang Qianhui: I guess it might be Aqi's birthday. By the way, why is Aqi so nice to Liu Xinyi? She seems to have been visiting Liu Xinyi's dormitory to play with her these past few days. I'm so jealous! ! "

Xu Qiubai opened Yingqi's WeChat homepage, which clearly showed that her birthday was in the first half of the year, the same day as she had stated verbally.

And Yingqi also said that she was looking forward to Xu Qiubai celebrating her next birthday.

Even if it was due to calendar customs, why did she deliberately hide it from herself and not from Liu Xinyi on Monday?

Xu Qiubai was a little confused about this problem.

After some thought, Xu Qiubai still chose not to ask.

-----------------

The next day, Sunday, Xu Qiubai called Kang Qianhui, who had come to deliver a camera, and his most trusted technical consultant Song Shiyu to the coffee shop in the commercial building.

Kang Qianhui didn't have any psychological trauma from the environment, and even ordered a cup of iced American coffee exactly the same as yesterday.

Song Shiyu was different. When he arrived at the coffee shop and saw Kang Qianhui, he was stunned.

Kang Qianhui was still very arrogant in front of outsiders. She simply greeted Song Shiyu and sat in the corner of the private room to play with her mobile phone, leaving the camera in Xu Qiubai's hands.

"Brother Bai, what's going on...?" Song Shiyu asked in a low voice.

"Don't worry about her, she's just paying the bills."

After Xu Qiubai gave Song Shiyu some delicious drinks, he began to integrate all the current information with him to see if they could come to a conclusion.

“Isn’t this the camera you asked me to check yesterday?”

"Yeah, Kang Qianhui's was also brought to the manor that day. See if you can find any clues."

With a head full of questions, Song Shiyu began to fiddle with the camera.

A few minutes later.

"No, this camera is a bit too complicated. I can't understand how to use it." Song Shiyu seemed to have a headache.

Then Xu Qiubai sent a message to Kang Qianhui and asked her to guide Song Shiyu.

Song Shiyu gradually got the hang of it, and then Xu Qiubai asked Kang Qianhui to return to her original position.

"Brother Bai..."

"Can't help it? Do you have to ask now?"

Song Shiyu nodded like a chicken pecking at rice.

"Just think of it as me adopting a little sister, OK?"

"Kang Qianhui's family is in the hotel industry... they are extremely wealthy!!"

"Alright, alright, let's go back and talk!"

"Brother Bai, you are awesome... You really need to teach our brothers..."

Later, Xu Qiubai asked Kang Qianhui to get Jiang Ding's camera as well. With Kang Qianhui's financial backing and as they were both camera enthusiasts, Jiang Ding readily agreed to lend it to him.

Sure enough, the video footage in the garden was not found in either camera, and the owners of both cameras said that they had not touched the storage inside.

After Song Shiyu entered the working state, he was very focused. He put all the clues on the tablet computer and made a very detailed mind map.

Xu Qiubai thought with him throughout the whole process. Finally, Song Shiyu let out a long breath and typed a "?" at the conclusion.

"I think this line of thought is really broken." Xu Qiubai spoke first.

But at this moment, Song Shiyu showed a very embarrassed expression. He glanced at Xu Qiubai, and then at Kang Qianhui who was drinking coffee happily in the distance.

"Brother Bai..."

"Just say what you want to say."

“It’s not broken, actually.”

"Not broken...?"

"Holmes once said to Watson: 'When you have eliminated the impossible, whatever remains, no matter how implausible, must be the truth.'"

Song Shiyu slowly deleted that? and typed three words in the "" that made Xu Qiubai's face change drastically.

"Zhang Yingqi".

Chapter 98 Logical Analysis

"Brother Bai, I know this conclusion will make you feel very uncomfortable... Even if someone else asked me, I wouldn't type it out...

But I know you are a logical person..."

After typing those three words, Song Shiyu hurriedly added some explanation.

The shock on Xu Qiubai's face still remained, but he raised his hand to interrupt Song Shiyu: "No need to stack armor, just continue talking."

Song Shiyu looked at Xu Qiubai with admiration again:

“There are two schools of thought now: there is such a person or there is not.

Of course, there is a possibility that there is no such thing, but in the general direction of the former, there is a possibility that is extremely consistent. In any case, we have to explore it. "

Xu Qiubai nodded in approval.

"Squad Leader Zhang established a very good friendship with our squad leader Liu at the beginning of the school year, so it was easy for her to find out where squad leader Liu was."

"Well, two outstanding military training students at the school level, both excellent correspondents in the department, one is a writer and the other is a photographer."

Xu Qiubai emphasized the word "photography".

"Then there's the video online of you and Squad Leader Liu clashing. Judging from the picture quality, it should have been taken by a camera with good configuration, but it was processed to a lower quality.

I asked a lot of people about this, and they all agreed that the way it was handled was a bit crude. You can also ask Kang, she should know a lot about this.”

Xu Qiubai nodded and typed a question to Kang Qianhui who was at the other end of the private room.

Kang Qianhui also came to a similar conclusion.

Song Shiyu looked at the two people who were clearly in the same room but had to communicate by typing, and his expression was a bit intriguing.

"Then there's the recording. I went to the counselor's office and it was very soundproof. With the door closed, it was impossible for that part to be recorded 'accidentally'. There were only four people in the room at the time."

The door was not closed tightly at that time, so Xu Qiubai couldn't be sure now, but what was certain was that Yingqi was the last person to enter the office.

Even if the door was not closed tightly, it was her fault.

In some ways, the difference is not that big.

"Then there was the initial series of unfounded photos. Excluding those taken with cell phones, some of the photos were taken from very close angles. Considering the fact that Squad Leader Liu was very vigilant, there probably weren't many people who could have done that."

"From my perspective, the photos in the manor are the least convincing, because many people have used that camera. Until you told me that classmate Kang also brought a camera and gave it to squad leader Zhang for safekeeping..."

"This is really, a bit too dramatic."

"I asked several people. The first person to leave the table that day was Kang. She took Jiang Ding's camera. Then it was squad leader Liu. Although a few people went to the bathroom during the meal, they were obviously drunk. Then it was you, Brother Bai. After that, it was squad leader Zhang. She was also out for a long time."

In fact, Xu Qiubai could have cited many more small details that Song Shiyu didn't know.

For example, Yingqi was the only one who understood the difference between discipline points and contribution points, and she was the first to suggest that Xu Qiubai participate in the school anniversary play to earn contribution points.

That night at the manor, Yingqi showed up just after he finished talking to Liu Xinyi. Kang Qianhui also said that she had been taking pictures of the stars by the swimming pool after she left. Then Liu Xinyi suddenly ran over angrily and scared her.

Combined with that person's cautious and resourceful nature, really, it all fits.

It was just that Xu Qiubai didn't want to believe it subconsciously, so he simply ignored it.

"Verify it more carefully."

Xu Qiubai once again remotely controlled Kang Qianhui and asked her to find out how Jiang Ding's camera had been used in the past month and a half.

As a result, his camera has been contributed to classmates since the beginning of the school year, and most of the time it is kept in Yingqi's dormitory. There are three people in that dormitory, among whom Jiang Xin is the organization committee member of Class 8, responsible for organizing various class activities.

But the class leaders of Class Eight were generally lazy, because most of the affairs were taken care of by the squad leader Yingqi.

Kang Qianhui also had a very good relationship with Jiang Xin. She knew that Jiang Xin had no interest in photography at all, and she was too lazy to touch Jiang Ding's camera, for fear that she would not be able to afford the compensation if it was damaged.

Then Xu Qiubai contacted Liu Xunyue again and confirmed that she and Liu Xinyi would celebrate Yingqi's birthday together on Monday. They had a lot of fun that day and she even bought the cake specially.

The moment he got the answer, Xu Qiubai felt an indescribable feeling in his heart.

Then Xu Qiubai asked Liu Xunyue a very crucial question: How did Liu Xinyi know about the discipline classification system of Donghai University?

If Liu Xunyue's answer was "I don't know" or "I heard it from my classmates", Xu Qiubai would only think about the problem based on one possibility.

However, Liu Xunyue's answer surprised Xu Qiubai.

Liu Xinyi has known this since she was a child.

When I just learned to read, I would read the book "Tunghai University Rules and Regulations" at home every day.

Xu Qiubai also learned that more than 20 years ago, when Tunghai University was just starting out, the "School Rules and Regulations" were strictly enforced on campus.

Now, more than 20 years later, this outdated "School Rules and Regulations" has become a major historical legacy within the school.

Even Liu Xunyue, a member of the school's supervisory board, has a large part of her job to promote the reform of school rules and regulations, but there is currently great resistance.

Xu Qiubai's thoughts were a little confused, so he switched to another channel of thinking.

For Xu Qiubai, he wanted to know the motive behind it rather than expose it.

If it was really Yingqi who did it, what was her motive?

Xu Qiubai really didn't believe that his girlfriend was hiding deep hostility towards Liu Xinyi.

If you really hate her, there's no need to go through so much trouble.
