Oops! My Wife Is the Demon Leader

Transmigrated into a martial world as a noble heir, Harrison awakens the Lay-Low System, becoming an unrivaled powerhouse on one condition—he must conceal his true cultivation. Seen as a useless “good-for-nothing,” he is publicly abandoned by his fiancée. He marries a gentle, fragile-seeming woman, hoping for a quiet life. Yet factions like the Sins Gang and Empyrean Sect push him to the edge. He endures in silence to protect her, only to discover she is the Demon Sect Leader, who has also been protecting him. When she is nearly killed, Harrison finally draws his sword and ends everything in one strike. From then on, they roam the martial world together as an untouchable couple.
