Outsourcer Gu Yi signed a soul agreement and became a regular employee, and his work badge was branded P7-C-013. The 13 people in the department are all dead souls, and only his left ear can hear the wail of the future.

It turns out that the KPI is Yang Shou, and the company itself is chewing on his remaining heartbeat.
