Knowing history doesn't mean you can change your fate; transmigrators aren't necessarily heroes.
Han Guang, a history graduate who had run into one obstacle after another in modern life, unexpectedly transmigrated to the late Tang dynasty and became Han Jiming, the son of a salt merchant. He thought that having read the Old Book of Tang would let him predict the future. But he hadn't realized that history textbooks never mention how the late Tang salt tax could drive people to their deaths, how rebel armies left nothing standing in their wake, or how surviving was harder than being a hero.
This is the story of one man's struggle against an entire age, and of an idealist remaking himself amid blood and fire. When the Great Song's banners finally fly above the walls of Bianjing, how will the historians write of that absurd era, when "three or five brothers alone were enough to make an emperor"? And as the aged Han Guang looks back on his life in the autumn wind, he finally understands: he transmigrated across a thousand years not to become a hero, but to realize that in everything he planned and thought, in every action he took, he had already become history itself.
