Mu Wanqing's father sent them to the elevator door and went back.

Mao Xiaofan on the side persuaded her: "Siyue, don't be afraid, we all believe in you."

Others also said: "Yes, we are all on your side, and you see that Wanqing also believes in you."

Lin Siyue smiled, and her heart was moved.

"Thank you, if you don't believe me, maybe this case will get even more troublesome."

Several people arrived at the police station, and the new male police officer in charge of the case was surnamed Xia.

Officer Xia saw that they were all students, and the tone of his questioning was relatively much kinder than that of the adults.

The questioning was conducted individually.

When it was Lin Siyue's turn, Officer Xia seemed to be a little tricky and said to her: "Classmate Lin, I hope you can provide me with as many details as possible, otherwise this case will be very unfavorable to you."

"When we went to adjust the monitoring of the bubble tea shop yesterday, we found that there was something wrong with the line over there yesterday, that is, now we have no direct evidence to prove your innocence."

Officer Xia patiently persuaded: "Think about it again, after you took the milk tea from the clerk until your classmate drank the milk tea, did anything happen during this period that made you suspicious?"

Lin Siyue thought carefully and said: "Milk tea has a lid, if it wasn't for the poison before it was handed over to me......"

Speaking of this, she suddenly remembered a small thing.

Lin Siyue excitedly grabbed Officer Xia's sleeve, "I remember, when I came out with milk tea, a man once touched me, and the milk tea in someone's hand next to me spilled a little on my body." ”

"At that time, I put all the milk tea on the table next to me, and then wiped my clothes with a tissue, it must have been at that time, my milk tea was changed."

Officer Xia glanced at her hand, nodded and said, "Classmate Lin, don't get excited, do you remember what that man looks like?"

"In this poisoning method, the other party must have a clear and definite target, and can ensure that the victim will be harmed, otherwise it is easy to be injured by mistake."

Lin Siyue said: "At that time, the man was wearing a mask, and I only saw a black mole the size of a grain of rice above his left eye."

"As for the accidental injury you mentioned, officer, in fact, I also suspect that the target of the poisoner was me, because I was the only one who ordered a cup of rose flavor that day, and Mu Wanqing would be poisoned if she accidentally took the wrong one."

Officer Xia listened thoughtfully, "That's right. ”

"Do you have anyone who is suspicious?"

Lin Siyue first thought of Su Qianye and Qian Mengmeng.

But she was still a little unsure, "I was a suspicious person, but those two were not there at the time. ”

Officer Xia picked up the pen and said, "Tell me the name, and then if your drawing skills are okay, it's best to draw the man's appearance, and we can conduct technical analysis."

When it comes to painting, this is not a difficult thing for Lin Siyue.

She borrowed a pen and paper from Officer Xia, and quickly drew the man's appearance.

Officer Xia glanced at it a few times, put away the folder and said to her, "Let's get here today, we'll call you when there is progress."

Lin Siyue walked to the door, remembered something and turned back and said, "Officer Xia, our school has a chemistry department, I suddenly remembered, is there a possibility that the poisonous reagent was stolen from our school?"

"In our school's chemistry laboratory, important reagents are kept by special people, and I don't know if they can provide a little useful clue."
