Gu Changzhou, a modern surgical master, traveled to a Yu Dynasty similar to the late Tang Dynasty, which was plagued by internal and external troubles, and became a young doctor whose family was in decline. At the beginning, he faced a desperate situation, but accidentally activated the golden finger of the knowledge database called "Tiangong Treasure House", which contains all the knowledge of the modern world from basic science to cutting-edge technology.
With his medical skills that transcended the times, he saved the dying prime minister of the dynasty and became famous in one fell swoop. Facing the decadent court, separatist vassal towns, ferocious aliens, and the impending peasant uprising, Gu Changzhou used medical skills as a shield and technology as a spear. While he was dealing with various forces in the court and accumulating political capital; at the same time, in his own fiefdom, he used the knowledge of the "Treasure House of Tiangong" to develop agriculture, smelt steel, manufacture gunpowder and firearms, and build a new type of army.
In the end, when the old dynasty fell apart, he swept across the world with his invincible appearance, pacified the world, personally created an unprecedentedly powerful civilization, and became the uncrowned king who stood above millions of people.
