Lin Che, a graduate student in the Department of History, was selected by an unknown being and embarked on the most cruel redemption - he had to travel through the absolute end of the Han Dynasty in history. The task he completed was not to "extend his life" but to "cure" the Ming Dynasty, the Tang Dynasty, the Northern Song Dynasty, the Three Kingdoms, the New Dynasty, the late Han Dynasty, the Southern Dynasty... He operated, exchanged blood, and rebuilt the bones of every dynasty that was destined to die.
