The realm of rules suddenly comes, and ordinary people struggle to survive. Yan Chuan mistakenly entered the F-class "Night Shift Convenience Store" while delivering express delivery. Others could only see three rules, but there were a few more lines of red letters in his eyes - "Article 2 of this rule will automatically expire after 22:07" and "Article 3 only takes effect for people wearing red work clothes." While others seek survival, he looks for loopholes. Fragments, permissions, hidden rules, mysterious observers... The more Yan Chuan walked forward, the more he discovered that his missing college roommate Huo Qingya seemed to have been waiting for him "deeper".
