The Dead Classmate Is Looking for Me in the Chat Group

Tonight is destined to be a sleepless night for Xu Yi. When he was about to graduate from college, the group chat on his phone that had been dormant for many years started ringing again. They seemed to be looking for Xu Ji anxiously. There weren't many people in the group, but they were all his close friends from high school. The last message was from five years ago. But Xu Ji couldn't be happy and had no idea of ​​reminiscing with old friends. Because he was the only survivor of the space collapse incident in Yunxi No. 1 Middle School five years ago.
