The Wall

The black shadow and Lin Sisi shared the same bedroom; he even knew Lin Sisi's phone password. This proved that they shared a more than casual relationship.

"I wish to know everything about Lin Sisi. This is related to whether we can escape from this school or not." Chen Ge opened his lips to ask, but the shadow did not reply, as if the name Lin Sisi was this school's taboo and discussing it would bring about some bad luck.

Slowly shaking his head, the shadow pointed at Chen Ge. He painted at the top of his head and then at the bottom of his feet. It was hard to tell what he was trying to express.

"Are you trying to say that what we're discussing might be overheard by something else?" Chen Ge tried to read the shadow's gesture. The shadow shook its head and then used his fingers to make out several words—'We've killed Lin Sisi. All of us are Lin Sisi.'
