Ye Changfeng transmigrates into the body of a useless second-generation immortal cultivator from the Taixu Sword Sect and binds himself to a Peak Master System that can only be activated once an elder is appointed. Using the elders' embarrassing secrets as leverage, he takes charge of Purple Bamboo Peak and becomes the Eighth Elder, activating the system. He takes in the genius disciple Su Wan'er and uses the system's resources to rapidly boost her cultivation. In return, her progress feeds power back to him, allowing him to reach the Sword King realm in just three months. He humiliates the elders during the sect examination and reveals Sword Venerable-level strength when repelling enemies, leading everyone to mistakenly believe that a Sword Saint is guarding the sect. To find his parents, he travels far to the Eastern Region and establishes a sacred land. After venturing into a forbidden area and rescuing his family, he unlocks the Sibling System, breaks through to the Sword God realm, and establishes the Taixu Divine Sect. He destroys the Haotian Divine Kingdom, obtains a fragment of an immortal estate map, uncovers the truth about the world, and then heads to the Demon Realm to find his eldest disciple and gather the remaining map fragments.
