What other stories about alchemy?

After Ge Hong's time, the story of elixir of life continued to attract many emperors. For example, Emperor Ai of Jin (Sima Pi, AD 34 1-365) was addicted to taking elixir and died of poisoning at the age of 25. Tuoba Wanggui (37l—409), Emperor Daowu of the Northern Wei Dynasty, set up a fairy workshop in the capital in the third year of Tianxing (AD 400) to "set up an imperial doctor and cook hundreds of kinds of medicines" (Shu Wei (1 13 official history), compiled by Zhonghua Book Company,13). (Shu Wei (volume 1 14) "Shi Lao Zhi" was collated by Zhonghua Book Company (1974), but Tuoba Si did not lose heart. "And the officials who refine medicines are still emerging one after another." It was not until several years later that it was ordered to stop because there was no result. However, after taking Wushi Powder, Emperor Daowu finally went insane and died. Taizu Tuoba Tao (AD 408-452) called Wei Wenxiu, who lived in seclusion in Gaosong, to the capital and asked about the alchemy at that time. He also sent ministers Cui Re and Wei Wenxiu to Wuwangshan, but failed. Later, he ordered Luo Chongzhi to visit immortals in the mountains, but failed. When Emperor Xiaowen (Justin, AD 467-499), Xu Jian, an imperial envoy, hoped to make elixir for Emperor Xiaowen and realize the "life-prolonging method", so he moved to Gaosong to collect elixir, but failed several years later and finally gave up the plan of elixir. Wen Xuandi (Gao Yang, 529-559) in the Northern Qi Dynasty was more cautious about the situation at that time. "History of the North, Art and Literature" said: "There was a long-distance traveler who ordered him to join the warlock nine times and turn to the elixir during the propaganda. And then, the emperor put a cloud in the jade box:' I am greedy for happiness on earth, and I can't fly to heaven until I die.' "So although he ordered refining then, but refused to take at ordinary times.
