Li Ergou, a modern truck driver, died in a car accident. His soul traveled through the Qin Dynasty and became a drug-testing boy under the alchemist Xu Fu. Xu Fu refined two secret elixirs of immortality for Qin Shihuang and forced him to test the elixirs. After his seven orifices bled, they were abandoned in a mass grave. When he woke up, he actually became immortal. In order to hide the secret, he kept his name anonymously and walked on thin ice. He managed to survive in the thousands of years from the Qin and Han Dynasties to the Qing Dynasty. He went through dynasty changes, Jianghu pursuits, alchemists coveted, and emperors spied on him. Every step of his life was startling, and he wrote a legend of immortality with ups and downs.
