Oops! My Wife Is the Demon Leader

The Sins Gang and then the Empyrean Sect come at the same man, one after the other, to humiliate him. Behind them the Demon Sect and the Dao Sect have begun to show themselves. The man they are pressing on is Harrison, the son of a rich family, whom everyone in the martial world takes for a good-for-nothing who cannot cultivate. Harrison was transmigrated into this world and woke the Lay-Low System. Through it he has become a master with no equal, on the condition that he hides his cultivation completely. Because he appears useless, his fiancée broke off their engagement in public. By chance he then married a gentle woman who seems fragile, and he hoped to sit out the last days of the system's mission quietly with her. To keep his wife safe he does what he can against the gangs and sects. Then he finds out that she is the leader of the Demon Sect, and that she has been guarding him in secret the whole time as well.
