【Case No.: 001】 【Patient: Yongning Town】 【Chief complaint: All residents have been smiling continuously for over three months】 【Doctors on site: 6】 【Time limit: 72 hours】 【Discharge condition: Complete treatment.】 【If treatment is not completed by the deadline, everyone dies.】 Lu Chen stared at the lines of printed text before him. He recognized the format. He’d worked as a pathologist for three years. Every day, his job was to identify a patient’s illness from a lump of tissue that revealed nothing at a glance.

The rest was up to him.
