In the Jiajing Dynasty, He Refined Elixir and Became an Immortal.

The art of alchemy has been practiced throughout the land of China for five thousand years. Huang Di's battle with Chi You was caused by alchemy. The First Emperor burned books and harassed Confucians in order to collect the elixirs. Genghis Khan's eastern expedition was also to seek the ultimate in alchemy. Su Yu, a later generation, came to this world of immortality where alchemy was respected. He started out as a catcher and eventually became an immortal by refining alchemy in the Jiajing Dynasty.
