Lin Chen, a doctor of military science at the National Defense University and a top researcher on the history of the Three Kingdoms, had a sudden cardiac arrest, and his soul traveled to Changbanpo in Dangyang in the 13th year of Jian'an. He became the infant Liu Chan, who has been scolded by later generations for thousands of years as "the unsupportable Adou".
The beginning is a hellish situation with a near-death situation: Cao Cao is surrounded and strangled by five thousand tiger and leopard cavalry, Liu Bei and his people cross the river and flee southward in a hurry, and his biological mother, Mrs. Mi, throws herself into a well to save him. Only Zhao Yun rides alone in the battle, protecting his infant who is less than one year old and fighting for his life in the sea of blood and corpses.
Lin Chen, who is well aware of Ji Han's rise and fall, adheres to the physiological limits of his age, uses his childish body to hide his clumsy plans, and uses actions that best suit his status to rewrite Ji Han's tragic fate time and time again. Changbanpo secretly decides the way out, Luofengpo wisely saves Fengchu, Tongyan resolves the dispute between Jingyi factions, bitter remonstrances are hard to stop but ultimately maintains the foundation of Jihan, Yiling is defeated and the situation is in danger, completely tearing apart the millennium label of "Mediocre Lord".
From a swaddling baby in Changbanpo to a young emperor left alone by Bai Di, he took over the mess caused by internal and external troubles, joined forces with Wu to fight Cao Cao, pacified Nanzhong, and launched the Northern Expedition, stirring up the Three Kingdoms with his thousand-year strategy. Everyone in the world thinks that Adou is fatuous, but they don't know that he will eventually take charge of this troubled world, revive the Han Dynasty, dominate the Three Kingdoms, and create an unprecedented Ji-Han legend.
