Another evening descended into twilight at White Pagoda City Third Middle School, where Mr. Liu, exhausted from grading papers, lifted his head and glanced at the empty desk in the adjacent office.
Although the offices of the senior high school teachers weren't connected, they shared a massive glass window. The end of the year was approaching, and the school was immersed in an intense year-end final review. At a time when all subject teachers were giving their classes a final push, Mr. Zhang had been on leave for four consecutive days.
It wasn't just Mr. Zhang; Zhang Xiaotong had also been absent for four days. This couldn't help but worry Mr. Liu.
Suddenly, the water cup on his desk began to tremble slightly, followed by violent shaking throughout the entire teaching building.
An earthquake? It must be. Cloud Sea Province is a frequent earthquake zone.
