Such an outstanding girl is not withdrawn or arrogant, she is approachable, her lively and lovely personality can get along with everyone, and she often helps others. Teachers and classmates like her very much.

At 16:40 on the afternoon of the 10th, after the last intensive training class of the day, Fang Fang and Yan Jing made an appointment to go to the cafeteria for dinner.

The semester has not officially started yet, and the total number of teachers and students participating in tutoring at the school is only thirty. In the three-story canteen, only the boutique area on the third floor is open.

Principal Qin later explained to the police that participating in the Mathematical Olympiad competition was to bring glory to the school. Not only did the school not charge any fees to the students for the half-month training course, it did not even charge for meals.

Fangfang takes care of the daily life of these twenty outstanding students and hopes that they will devote themselves to their studies and achieve good results in the competition.

No one expected that around five o'clock in the afternoon on the 10th, Fang Fang and Yan Jing walked into the cafeteria together. As soon as they entered the door, Fang Fang told Yan Jing that she wanted to use the restroom, and the two walked into the women's restroom on the first floor.

Although the canteen on the first floor has never been open, the restrooms can still be used normally.

However, in just a few seconds, Yan Jing washed her hands outside and asked Fang Fang some difficult questions explained in class, hoping that this famous little genius could help her, but Fang Fang did not answer.

Regarding the entire process of Fang Fang's disappearance, there is only this description in the police file - she opened the door and walked into the single toilet. Yan Jing asked questions outside the door, but Fang Fang did not answer. Yan Jing turned around and dropped her mobile phone on the sink.

On the ground, she bent down to pick it up and found that there were no feet in the single toilet room that Fang Fang entered...

There were no human feet in a single toilet that was supposed to be occupied. Either the person was standing on the toilet seat, or it was a common horror movie plot.

But the school uses a squatting position. As long as someone is in a single toilet, their feet can be seen no matter how they stand.

Fang Fang disappeared like this. From opening the door to closing the door, to Yan Jing bending down to pick up the phone, it was all done in one go.

Yan Jing said it would take about ten seconds, but I thought it might only take six or seven seconds for those mysterious and vicious hands to take Fang Fang away!

"Yan Jing withdrew from the training class and left the school because of this incident. Other classmates also reported that she and Fang Fang did not have a good relationship, so the police were skeptical of this testimony. More importantly, Fang Fang died of strong corrosive liquid sulfuric acid

, the appearance and internal organs have been completely destroyed... What do you think of this?"

Liu Su put down the information and asked me with slightly squinted eyes. His relaxed expression seemed to be asking me to solve a puzzle of deciphering numbers.

After thinking about it, I looked serious and said cautiously: "In the previous cases, all the victims died from items in this school building. Maybe we should ask Principal Qin if there is sulfuric acid here."

Liu Su nodded, seeming to agree with my idea, and then asked: "Then why do you think the relationship between Yan Jing and Fang Fang is not good?"

"Jealous. Maybe he's jealous of Fang Fang's appearance and talent, or maybe he's jealous of the fact that there are too many boys who like Fang Fang. If the boy Yan Jing likes happens to like Fang Fang, the relationship probably won't get better!"

After hearing what I said, Liu Su smiled: "Yes, women's jealousy is extremely powerful."

I then said: "But the jealousy of a twelve or thirteen-year-old girl may not necessarily kill a person!"
