All ten members of the Ten Diligent Days are villains. The story takes place in an enormous, isolated base that appears to be conducting an experiment in modern agricultural reform: the "Houtu Project" experimental zone. The land is vast, the facilities are advanced, but management is strict and information is tightly controlled. The members of the "Ten Diligent Days" aren't simple farmers or interns. Each was "selected" or "exiled" here with secrets and motives of their own. Beneath the facade of "hard work," each one harbors an evil side: past crimes, present schemes, or a twisted nature born of desperation.
