Ying Huaixu, a professional game player who boosts other players' accounts, transmigrates into a world of immortal cultivation on the game's Hongmeng difficulty setting. Bound to a gaming system and possessing a Dao Sword spiritual root, he knows the entire storyline of the world.

He saves Ye Ningshuang, the fated female protagonist, meets Qiu Shiyi, He Xiuyuan and others, and becomes He Xixiang's disciple. After entering the Divine Firmament Sword Sect, he rapidly improves his cultivation through the system, learns top-tier complementary ice techniques, and obtains the special ice sword Frost Annihilation. While completing quests to accumulate resources and helping those around him grow stronger, he gradually realizes that the world's storyline is constantly deviating because of his actions. An unknown crisis in the Illusory Dream Mountains is quietly approaching, and countless uncertainties lie ahead.
