Traveling through the Qin Dynasty, Zhao Mushan inherited the golden job of the jailer from his ancestors. He originally wanted to live in peace and farm, but he unexpectedly gained immortality. Unexpectedly, Lao Ai taught him the art of turning the wheel, Lu Buwei taught him how to do business, Han Fei taught him the essential skills of governing a country, and Meng Tian taught him the art of leading an army. When the First Emperor came to the east with hundreds of officials to invite the master to come out, Zhao Mushan immediately became numb: "Stop praising me! I am really just an ordinary jailer!"
