Sin-Mark Green Lotus: From Live-In Son-in-Law to Slayer of Demon Gods

Yu Jin transmigrates to the Yin Kingdom and lands the miserable role of a county magistrate's son-in-law.

From the start, he awakens the Crime Mark Record System and the Azure Lotus Sacred Body. From then on, he can see crime marks floating above people's heads. Thieves and murderers? One glare is all it takes to expose them! He earns crime points by bringing criminals to justice, then happily spends them on divine techniques and gadgets for picking up girls.

By day, he solves cases and catches thieves: “Hey! That ‘bullying men and dominating women’ mark of yours is blinding my sacred eyes!”

By night, he puts out fires in his love life. With his wife hunting him down, he still has to placate her lovesick best friend (“Brother Yu Jin~ You're next~”), dodge his fiery senior sister (“You scoundrel! Where do you think you're putting your hands?”), soothe his icy fairy master (“You wicked disciple! Had enough of that hug yet?”), and flirt with the tsundere eldest princess (“How dare you, son-in-law... Come back to the palace with me so we can talk!”).

Yu Jin: Solving cases, getting rich, and picking up girls? This System should be called A Guide to Conquering the Harem!

Onlookers across the Yin Kingdom: A cheat code in the crime-solving world, a walking disaster in the dating scene! Why is this son-in-law so unlike any other?
