Under One Person: Did Zuo Ruotong and I switch bodies?

Mingchen’s journey begins with a gift and a goal: the awakened "Celestial Eye," a power that pierces the veils of heaven and earth, revealing the hidden truths of cultivation. With this sight, he sets his sights on Longhu Mountain, seeking enlightenment at the heart of the Taoist world. But fate has a crueler twist in store. He awakens not on that sacred peak, but in a different body, in a different era—the tumultuous Republic of China. He is now Zuo Ruotong, the infamous Daying Immortal, and the first face he meets is that of a young disciple, Li Muxuan, come to study under him. His first act as this legendary master is to strike the boy across the face, offering only the cryptic reprimand: "Why did I hit you? That is for you to discover." Meanwhile, the true Zuo Ruotong opens his eyes in Mingchen’s modern body, only to find the world he knew has crumbled—the Trinity Sect has long been disbanded, its glory reduced to dust. Driven by an urgent need for answers, he delves into a century of lost history. As their fates intertwine across time, two contrasting legends take shape. In the chaotic Republic, a ruthless sect leader arises, infamous for his brutal discipline, yet his harsh hand forges three peerless disciples and elevates the Trinity Sect to an unprecedented golden age. And in the modern era, a mysterious young immortal emerges, one who masters the ancient arts without a teacher, shattering the three shackles of reverse birth through sheer, inexplicable will. As both men walk in each other's shoes, they must uncover the truth behind their swap—and the cosmic thread that binds two eras, two identities, and one inescapable destiny.
