Su Qingyu looked at the man's face and nodded slightly: "Yes."
After the explosion, black dust covered the man's face and body, covering his original skin. According to the corresponding rules, the "safety officer" has black skin.
He was wearing sneakers, with half of his ankles exposed, and walking normally on his feet.
There is a work ID hanging around his neck.
His entire body was covered in black dust, except for his work ID, which was clean and tidy, and even the photo on it was brand new.
The middle-aged man's attitude was not enthusiastic.
He simply placed the experimental equipment in his hand into Su Qingyu's hand, then waved at her, indicating that she should follow.
Passing through a door, the middle-aged man used his work ID to open the electronic lock.
Next to the door was a sign saying "Staff Passage".
This passage is as old as the secure laboratory.
Rows of dim lights flickered, the cracks on the walls were as dense as spider webs, the air was filled with the smell of dampness and confinement, and the thick dust underground seemed as if no one had walked for a long time.
Following the man, Su Qingyu soon arrived at the exit on the first floor.
After returning the experimental equipment to the middle-aged man, she quickly left the chemistry laboratory building.
The middle-aged man found a towel and wiped the black dust off his face, then he looked at Su Qingyu who was leaving and gave her the same terrifying smile he had given in the elevator at the beginning.
The middle-aged man waved to Su Qingyu again.
Su Qingyu ignored him.
He stood on the first floor for a while, then walked back to the elevator and pressed the switch.
Zhuang Xiaodie had been waiting outside the chemistry laboratory building for a long time. She clutched her sleeves and kept looking inside. If Bai Huo hadn't been stopping her, she would definitely rush in to find Su Qingyu.
"Ten minutes have passed, a full six hundred seconds. It's weird that one second can twist off a person's head, so six hundred seconds is enough to twist off another person's head!
No, it's too dangerous for Qingyu to be alone in there, I have to go find her." Zhuang Xiaodie was so anxious that she turned around in circles.
As soon as Su Qingyu came out, she saw Zhuang Xiaodie who was like an ant on hot pot, Luo Zixuan who looked impatient, and Bai Huo who was always peaceful and calm.
“Qingyu!” Zhuang Xiaodie rushed over immediately and buried her head in her shoulder. “Wow, that’s great, you finally came out. If you were stuck in there, I would never live alone!”
Su Qingyu patted her head and asked, "How did you get out?"
Zhuang Xiaodie hooked her hair that fell on her chest with her fingers and said, "We were lucky. After we finished the experiment, the elevator showed that we were on the third floor, but the door opened on the second floor. We followed the rules and took the elevator directly to leave."
This is where the heroine's halo comes into play.
"Can we go back to the dormitory?" Luo Zixuan was full of resistance to the chemistry laboratory building. She just wanted to get away from here.
Su Qingyu took out her cell phone. Just now during the class, her phone kept sending her new message notifications.
The head teacher actually tagged Su Qingyu nearly forty times in the group and repeated the same content.
Chinese teacher: Give me the class funds!
Chinese teacher: Give me the class fee!!
Chinese teacher: Give me the class fee!!!
Words have no emotions, but Su Qingyu saw the manic murderous intent in the dense messages from the head teacher.
