My Roommates Played the Spirit-Writing Game and All Died. How Can I Save Them?

"Yang Fan, tell us the truth. What happened in your dorm on the night of October 1? What did you see?" The interrogation room's white lights were blinding, and the metal table was cold. The young police officer leaned forward, his voice low. "Officer, I already told you.

I do it as a side job." "Did they ask you to join them?" "They did." "Then why didn't you play?" I fell silent. The officer slapped the table. "Five people are dead, and they were all your roommates! You have to explain yourself!"
