Lin Yan, a high school senior, has been lonely and helpless since childhood. After being adopted by a kind foster father, he finds himself surrounded by a sweet, gentle younger sister and a brother who would always have his back. He plans to keep his head down and study, get through his final year of high school, take the college entrance exam, and live an ordinary life.
His biological father is the greatest Sword Sovereign in the world of the Xuanwu Continent. While attempting to break through to the Heaven-Opening Realm, he is ambushed from behind and cruelly betrayed by his most trusted friend. Gravely wounded and on the brink of death, he tears through space and time, accidentally falling into the modern mortal world, where he encounters the Holy Maiden of Yaochi from another cultivation world.
They meet, fall in love, and marry in the mortal world, sharing a peaceful life together. But their happiness does not last. Powerful figures from the Holy Maiden's sect cross worlds and forcibly take her back to the cultivation realm, imprisoning her and separating them.
Starting in the halls of high school, he takes up the Mysterious Jade, inherits the Sword Sovereign's path, and steps onto the road of cultivation. He will settle his scores with his enemies and find the Holy Maiden, his mother. With a single sword, he will shatter the mortal world, roam the Xuanwu Realm, and rise against the heavens, sweeping through all the worlds and domains!
