Classmate, You're a Lucky Fish! I Earned Merit by Lying Down

Intern police officer Lin Ran accidentally gains the Luck System. He initially intends to win big prizes through it, but keeps stumbling upon solving major cases by accident. He catches pickpockets, captures robber Zhang Ming, and takes down fraudsters. His master Su Wan transforms from dissatisfaction to recognition, his father shifts from skepticism to pride, and he grows from a workplace rookie into a hero of the police force who builds extraordinary merit using his 'troublesome' system.
