The King of Hades's Urban Disguise

He was the \"King of Hades,\" a peerless demon of war who left trails of heads in his wake. But when the invincible soldier king returns to the city, his masters force him into the most absurd mission yet: protecting a glacial CEO, Su Qingxue, who dismisses him as a 'migrant worker' and shoves him into a sales department. Humiliation? Not for Wu Yi. His legendary internal energy makes him untouchable, his sharp tongue infamous, and his flirtatious smirk drives everyone mad. As corporate rivals and shadowy assassins target Su Qingxue, Wu Yi must balance his secret identity as the world's most dangerous man with his new role as the company's least competent (and most perverted) salesman. Can he protect her without revealing the true devil hiding beneath the disguise, especially when she just declared him her fiancé to spite her enemies?
