Summer's Last Echo

Four years ago, a mysterious mass death occurred at a high school in Ningbei. All 42 students in the class and their substitute teacher perished.

At the time, the incident had a devastating impact, and the entire city was gripped by panic.

However, all information about the incident was strictly sealed off. People only heard that it was an accident, but nobody believed that explanation. The case was riddled with unanswered questions. Perhaps it would become a strange mystery, forever buried in the sands of history.

Yet a letter from four years ago has once again drawn back the curtain on this mysterious, suspenseful tale.
