Villain Cultivator: I Force-Marry the Future Empress

Old clan leader Fang Ye, with his lifespan nearly ending, accidentally activates a system that grants longevity, cultivation techniques, and pills upon forming karmic bonds. He publicly slaps his rebellious son, regains his youth, and surges in power. Tasting success, he marries Gu Qingyi and aids the Ninth Princess in ascending the throne. The destined son Lin Feng, having lost everything, falls into the demonic path, attempting revenge multiple times only to fail miserably each time. Ultimately, empowered by the collective will of the people, Fang Ye shatters the avatar of the Heavenly Dao, becomes the Guardian Divine King of Great Xia, and reigns supreme under the heavens.
