Fusu, the eldest son of the Qin Dynasty, accidentally traveled to the modern city of Jiangcheng when he was accused of being wronged and drank poison. The otherworldly sight of tall buildings like forests and chariots and horses like dragons subverts his lifelong understanding; the mysterious "immortal cultivation system" is accidentally bound, opening up a path to immortality for him that defies heaven and changes his destiny.
As a descendant of the Great Qin Dynasty, he carried the tenacity and spirit of the ancients to survive in the concrete jungle: he learned to use mobile phones, apply for ID cards, and work odd jobs, clumsily but persistently integrating into modern society; he practiced Qi and blood, practiced martial arts, and slayed evil spirits, using his immortal power to fight against the strange phenomena and remnants of otherworldly things lurking in the city.
From the ignorant survival in Jiangcheng night market to the narrow escape of adventure in the secret realm; from the humble struggle of a mortal body to the supreme honor of being in charge of all things. While he is exploring the mystery of time travel, he is trying to find an opportunity to return to the Qin Dynasty and change history; at the same time, he is emerging in the modern world of immortality, making friends with confidants, gathering fellow practitioners, and uncovering the shocking secrets of the fault line between ancient and modern immortality.
When the legacy of the Qin Dynasty collides with modern civilization, and when the emperor's mind merges with the path of cultivating immortals, Fusu will eventually find a path that is unique to him - using immortal power to reverse time, using Taoism to determine the universe, reaching the top in another world, and all Taoists becoming one.
