During the Kaiyuan period, alchemy was popular in Chang'an. Taichang Temple secretly trains "Elixir Puppet" - to refine dead soldiers with gold, stone and elixirs. The person who has been refined has white hair and red eyes. He can carry a cauldron, but has lost his mind and is called "Jade Shura".
