Lin Mo, a modern restaurant owner and military fan, accidentally traveled to Shanghai in the 1930s and activated the "god-level selection system." Forced by the death option issued by the system at the beginning, he reluctantly accepted the undercover mission of the patriotic organization, codenamed "Cook".
Relying on the [High Risk High Reward] and [Outrageous Funny] options provided by the system at critical moments, Lin Mo used modern people's knowledge and various Internet memes to repeatedly jump between Japanese invaders, warlords, gangs, spies and other forces. On the surface, he is a wise and foolish restaurant owner who cannot offend anyone, but secretly he has repeatedly completed impossible tasks, intercepted key intelligence, and punished traitors and bullies.
In the process, he had various ridiculous emotional entanglements with the mysterious beautiful agent, the innocent warlord's daughter, the quirky school belle and others. In the end, Lin Mo relied on his system and wisdom to smash the enemy's huge conspiracy, and became a unknown but ubiquitous "King of Spies" legend in Shanghai.
