My Live-in Husband Is a Hidden Master

Cultivator Flynn, the General's master, descends for revenge, only to enter a contract marriage with the Wan heiress. Mocked as a useless son-in-law, he casually saves lives with spirit medicine and revives a tycoon with talismans. No one knows he mentors the world’s richest and serves as Dragonia's Grand Maester. When the Zhou family's backer arrives, they discover the Maester came not to aid them—but to annihilate them.
