He knew that the Qin Dynasty only lasted for fifteen years, and he knew that Zhao Gao wanted to tamper with the imperial edict. He knew that the emperor in front of him was about to die on the east patrol road. When Qin Shihuang asked him "How many generations can Qin live in?", He replied: "The second generation will die." Everyone thought he was crazy. Until he used modern knowledge to solve strange cases, quell food shortages, and calculate natural disasters, and step by step from death row to court. Zhao Gao wanted to kill him, Li Si wanted to demote him, and the remnants of the Six Kingdoms wanted to kill him. And he only wants to do one thing - to live and let the Qin Dynasty pass on to all generations.
