So, the reason why those girls were possessed is quite straightforward: they all used facial masks.
"How do you plan to confirm this?"
Song Yutang took a deep breath, making a decision.
"Student Cen, please accompany me to the dormitory."
They quickly arrived in front of the dormitory,
"I live here." Song Yutang pointed out the direction.
The door was tightly closed; she knocked on the door panel.
"It's Song Yutang, open the door."
No one responded until she repeated it again and finally heard a response from inside.
"Don't, don't come over!"
The tone of the girl behind the door was strange, a mix of nervousness and fear.
"I'm not going to open the door!"
"Cao Ying, don't you know what happened downstairs? Someone died, it's frightening, I want to come in and hide."
"I know... So, you, you just find another place, or you can go to the opposite dormitory."
The group outside exchanged glances.
"What are you worried about? It's just me outside, why not open?"
