Lu Xing's breathing stagnated slightly, and he subconsciously pressed the phone, and he looked around quietly.

The surrounding classmates were in a hurry, and everyone looked preoccupied, and they didn't notice her strange appearance for a moment.

She reluctantly settled down, held her phone and walked slowly to the end of the silent corridor.

Pushing open the door at the end of the corridor, there was a platform on the third floor, Lu Xing turned around and fastened the lock of the door, confirming that there was no one else on the changing table, and then she slowly pressed the phone.

The mobile phone, which was still vibrating just now, has completely quieted down at this moment.

Lu Xing hesitated to click on the missed call and dialed the call back.

In just a few breaths, the person on the other end of the line picked up the phone.

"Lu Xing, what the hell is going on? Does this matter have anything to do with the concentrated sulfuric acid I gave you some time ago? ”

The person on the other end of the phone barely lowered his voice, and he could hear that he was hiding somewhere and secretly making a call.

Lu Xing's heart was worried, the hand holding the mobile phone was slightly stronger, and his fingertips were slightly white: "I ......"

The person on the other end of the phone heard her hesitant voice, and immediately asked in disbelief: "Does this matter really have anything to do with you?" OMG. ”

"Lu Xing, are you mistaken? This incident almost killed someone, and I want others to know about this incident......"

"Xue, senior misunderstood."

Before the person on the other end of the phone could finish speaking, Lu Xing interrupted the other party in a hurry.

She took a deep breath, her thoughts racing in her head: "This incident has nothing to do with me or you. ”

"The last time I asked you for concentrated sulfuric acid, I didn't explain it to you, I just wanted to corrode the combination lock of my cabinet."

She smiled reluctantly on the other end of the phone, as if she wanted to deceive herself with the lie, and as if she wanted to make her tone sound more sincere.

"Really?" When the person on the other end of the phone heard him say this, he became suspicious again.

But after thinking about it, this Lu Xing is only a girl in her early twenties after all, how could she have such a vicious mind.

The person on the other end of the phone breathed a sigh of relief, but he was still a little uneasy, and said again: "Hey, it really scared me to death." ”

"Lu Xing, it's not that I'm too suspicious just now, it's that I'm really worried about you. Your recent infatuation with that Song Huailing has been a little abnormal, I promised Aunt Lu to take good care of you, but there are some things, I am a man, but I can't say more......"

Speaking of this, the person on the other end of the phone paused slightly, and couldn't help but say, "Today, the police questioned the rest of our lab. ”

"They didn't know that I had taken the sulfuric acid reagent, and I didn't say anything about it in order to avoid causing other unnecessary trouble."

"Although I believe that this matter should have nothing to do with you, the sharp judgment of the police...... I really hope this has nothing to do with you.

Lu Xing listened to the person on the other end of the phone and stopped, and immediately reacted to what the other party wanted to say, and when he nodded, he responded: "Senior, don't worry, I won't tell anyone about concentrated sulfuric acid." ”

When the person on the other end of the phone heard this, he sighed, and told Lu Xing a few more words before hanging up the phone again.

Lu Xing pinched his phone, and the expression on his face finally relaxed.

The person who just called was the son of her family friend, a graduate student majoring in chemistry at school, and she had known her since childhood, and she would ask for help with anything at school.

She did ask the other party for concentrated sulfuric acid in the laboratory some time ago, and asked for a lot.

At that time, the senior of the chemistry department also asked her what she wanted to do with concentrated sulfuric acid.

Her explanation at the time was that she had forgotten the password of a locker this time, and wanted to use concentrated sulfuric acid to corrode the locks of the locker.

When the senior heard her words, although he was a little worried about the danger she would encounter if she didn't operate properly, but under Lu Xing's repeated assurances, the senior still agreed to give him concentrated sulfuric acid.

After that, Lu Xing handed over the concentrated sulfuric acid to another person, Li Long.

She and Li Long's plan at the beginning was just to use the hanging shed to scare Xia Ning, if they happened to be able to smash each other, they didn't think it was anything, after all, it was just Xia Ning's bad luck.

As a result, it didn't come to pass, maybe it was a mistake in the organ, or for some other reason, the hanging shed really fell down in the end, and even almost smashed on Song Huailing's body.

She felt guilty and scared in her heart, it was just a prank, but for some reason it turned into a deliberate murder.

The more Lu Xing thought about it, the more he felt fear in his heart, and he couldn't help but pick up the mobile phone in his hand, raised his hand and dialed Li Long's number.

The busy voice on the other end of the phone thought for a moment, but no one answered for a long time, Lu Xing gritted his teeth, and his expression was a little ugly.

What's going on? Is this man ready to give himself up? No, she couldn't let that happen.

She is only in her early 20s, how can she let her future be buried in the pranks designed by others.

Lu Xing secretly gritted his teeth and turned around to leave the changing channel.

At the same time, outside the school's temporary interrogation room, Zhou Qin had just greeted the teacher, and when she left the room, she suddenly stretched out a hand in the darkness and hurriedly pulled her to the corner of the corridor.

"Why did the teacher call you here today?" Li Long looked a little nervous, and even a little cold sweat oozed from his forehead, looking a little weak.

Zhou Qing's gaze turned around on her face, and then she said quietly, "What are you nervous about?" ”

Li Long didn't expect that his false disguise would be easily seen through by the other party.

He wiped the cold sweat on his forehead with his hand, barely hooked the corners of his lips and smiled: "I'm just a little hot, and the weather is too stuffy today." ”

I don't know if his words fooled Zhou Qing, the tall woman raised her eyebrows, but she didn't continue to say anything.

Li Long saw that the other party was about to leave, gritted his teeth and stepped forward to stop her.

"What did the police, the police ask you?" His eyes were slightly red, and his whole body seemed to be immersed in an indescribable horror.

Zhou Qing looked at him expressionlessly for a moment, and suddenly spoke: "You don't have to worry, you didn't have anything with me after 7:30 yesterday, and I didn't tell anyone." ”

She slowly hooked her lips and smiled: "Could this matter really have something to do with you?" ”

"You left in a hurry after 7:30 yesterday, I thought you had something to do, but I didn't expect ......"

"Y-You're mistaken." Li Long's body trembled violently, and then he hurriedly said: "This matter has nothing to do with me, you know, I don't know any chemistry majors at all, how can I get concentrated sulfuric acid?" ”
