Li Fei, a cautious office worker from Earth, is reborn in the Great Lan Dynasty, a world where martial arts reign supreme and corruption festers within the Inspection Court. After witnessing the brutal murder of a civilian by the Tiger Saber Gang and the subsequent cover-up by authorities, Li Fei resolves to walk the path of the warrior. Adopted by a high-ranking official whose life was saved by Li Fei's father, he chooses to enter the Martial Arts Hall instead of university to avoid burdening his benefactors.

However, Li Fei harbors a secret advantage: an inexplicably thick health bar that grants him unparalleled survivability. In a realm where one misstep means death, Li Fei's ability to endure fatal injuries transforms him into an unstoppable force. As he navigates a society rife with gang violence, bureaucratic schemes, and hidden martial secrets, Li Fei must leverage his unique trait to survive, protect the innocent, and perhaps even cleanse the rot at the heart of the dynasty.

His journey from a cautious transmigrator to an indomitable Martial Saint begins now.
