Amid the collision of technology and tradition, a soul from the future reshapes the fate of an empire.
Li Shi, a leading scientist of the 21st century, accidentally transmigrates to the Tang Dynasty at the height of the Kaiyuan era. Armed with modern knowledge and an understanding of history, he intends to keep his head down and survive, but unexpectedly gets swept into a maelstrom that will change history. From an ordinary official in the Bureau of Astronomy to a pivotal figure influencing the entire court, every decision Li Shi makes quietly alters the course of the Tang Dynasty.
Yet as his influence grows, so does the pressure from all sides. The doubts of the conservatives, warnings from the Space-Time Administration, threats from the Turks, and his own anxiety about changing history all become challenges Li Shi must face.
In this turbulent age, how will Li Shi balance modern knowledge with ancient wisdom? Can he bring progress to this great empire without triggering drastic historical changes? More importantly, with the future he may never return to, how will he define his identity and mission?
