About half an hour later, Liu Hui returned to the classroom from the conference room. She put a stack of summer vacation homework on the podium, walked up to Meng Ziqing and asked, "Have you finished writing all the supplementary exercises?" ”

"It's done, we're all judged." Meng Ziqing handed the test paper to Liu Hui.

"By the way, what about Squad Leader Mu Mu? Where did she go. Liu Hui looked left and right and asked.

Chu Yunxi coughed lightly and got up to explain, "Teacher Liu, the squad leader just went out. ”

"Get out? It's been half past six for a long time, and it's dark outside. Liu Hui frowned and said.

Meng Ziqing also saw the darkening sky, and she suppressed the increasingly strong uneasiness in her heart, "Teacher Liu, let me go to the bathroom to take a look." ”

Liu Hui nodded.

Fang Kexin quickly sensed the uneasiness in the air, she and Xiao Bai looked at each other, and a bad thought flooded into her heart.

After a while, Meng Ziqing hurriedly ran back, "I called all the bathrooms on this floor, and no one answered me." ”

At this moment, an hour and a half has passed since the end of school, and the students on the huge campus are basically gone, and only this classroom is still lit.

"No one? How can this be, don't write it yet, I'm worried about whether Mu Mu is lost. Liu Hui pushed his glasses and took out his mobile phone to dial the number.

Everyone looked at each other.

The phone was connected, and Liu Hui asked directly, "Mu Mu's mother, I told you before that I wanted to keep Mu Mu at school to help my classmates with tutoring, but now that she is no longer in the classroom, has she returned home?" ”

"What, I'm sorry, Mr. Liu, my child and her father are both in the company, I'll call the landline at home first."

"That's the case, I'm also worried about Mu Mu, I'm sorry for you." After Liu Hui finished speaking, she hung up the phone, she turned to her classmates and said, "Everyone help the teacher find Guan Mumu, but you must not leave the school, if you can't find it, come back immediately." ”

"Okay." The crowd said goodbye and ran in different directions.

Xiao Bai pulled Chu Yunxi to the corner of the stairs and asked in a low voice, "Brother, you said that the squad leader and her parents don't care, what do we care?" ”

"Don't talk nonsense, no matter why Guan Mumu left early, if we don't help, Teacher Liu will be responsible for the problem in the end. She's a nice person, you don't want her to leave, at least not to. ”

"Alright then, I'll take a look at the activity building." After Xiao Bai finished speaking, he ran to himself.

Shuttling through the darkening corridors, Xiao Bai had to suppress the fear brought by the darkness. Each of the separate activity rooms was locked, and Xiao Bai could only see darkness through the transparent glass.

But this also shows that Guan Mumu will definitely not be here.

Inexplicably afraid that something would suddenly burst out of the classroom, such an idea came to her mind, and she was so frightened that she quickly jumped out of the door and hid far away.

She inadvertently swept the window on the other side of the corridor, and there was someone on the phone in the phone booth outside the teaching building, and she took a closer look, and that person was Meng Ziqing.

Maybe tell her parents, Xiao Bai suppressed the strangeness in his heart and continued to check one by one.

She was on the fourth floor, all the way down, just in time to see all the classrooms in an S-shape.

However, when Xiao Bai came to the second floor, she suddenly saw a door open abruptly, and the dim light was faint through the crack in the door.

"Mu Mu squad leader?" Xiao Bai called tentatively, and seeing that no one responded in that room, Xiao Bai ran over without hesitation.

No matter who is there, this time is not supposed to be.

Pushing open the solid wooden door, Xiao Bai didn't find anyone at a glance. It is a classroom for students to practice vocal music, with a curtain on one side of the door and various vocal equipment on both sides.

"Mu Mu, are you there? The teacher is worried about you, so if you are there, come out quickly. Xiao Bai coaxed softly, and walked into the depths step by step.

Suddenly, she heard the faint sound of footsteps behind her, and when she turned around, she saw a figure flashing out the door and closing the door. Before she could react, the sound of the lock clattering echoed unusually clearly.

"I'll go, how could I ......" Xiao Bai covered her head and squatted down, she should have checked the curtain one by one, but who was that person, who was she to lead her here and lock it up?

The person saw that the back was a girl, and Xiao Bai's first reaction was that this person was afraid that it was not Guan Mumu.

But she immediately dispelled this thought, where did she know that she would definitely go back to her, there were too many uncertainties. So who is that? She is usually very restrained, and she didn't mess with anyone, Xiao Bai frowned.

"Iwaba!" She was suddenly startled, and connected these things back and forth, and the only thing left was this person.

The ensuing distress was that she didn't know how long she would have to stay in this increasingly cold classroom before being discovered. She took out a large bag of costumes from a corner and spread them on the floor.

She tugged at some spare curtains and wrapped them around her shoulders.

The walls of the vocal music classroom are blessed with a layer of soundproof materials and noise removal materials, so that people outside can't hear what people sing inside, and people inside can't hear how ugly they sing.

These are all things that the teacher has said in music class, so Xiao Bai will never waste a little effort to ask for help.
