Villain? No, I'll catch up with the protagonist after passing the civil service exam.

Transmigrated into the body of a wealthy villain destined to see his entire family wiped out by the overpowered protagonist, Lu Jingyan chose the most logical path for survival: he studied hard, passed the civil service exam, and joined the city bureau's special investigation team. Bonded with the "Light System of Righteousness," he grows stronger simply by enforcing the law and putting criminals behind bars. When a domineering CEO tries to forcibly kiss the female lead, Lu Jingyan slaps on the cuffs for suspected indecent assault and illegal detention. When the almighty "Dragon King" returns with an army of one hundred thousand, Lu Jingyan dials the special police to arrest the lot for organizing criminal syndicates and illegally possessing weapons. Facing manipulative villains and untouchable elites alike, he offers no dramatic showdowns—only cold, unyielding justice and a pair of silver bracelets. In a world ruled by plot armor and overpowered tropes, one man proves that nothing beats the absolute authority of the law.
