Fu Nanguang and Yu Luoyi fell down the same stairs on the same day. Fu Nanguang thought he was dead, but accidentally entered Yu Luoyi's mission world when the system bound her...
Fu Nanguang: Can I still go home?
Silly System: It should... Be possible. Just steal enough mission points.
Fu Nanguang: Why... Steal?
Stupid system: Because I am just a useless product (＞＿＜;). Nanguang, let's go secretly so we don't get discovered.
