The Elixir Theft Case

"Gui Zang" records: "Yi asked the Queen Mother of the West for the elixir of immortality." The Queen Mother of the West agreed and gave Hou Yi the elixir of immortality. Later, Chang'e stole the medicine and flew to the moon. "The candle shadow on the mica screen is deep, the long river is gradually setting and the dawn stars are sinking. Chang'e should regret stealing the elixir, and the blue sea and blue sky are in my heart every night." Did Chang'e really regret it? Why did she steal the "elixir" and how did she steal it? "The Book of Mountains and Seas·West Mountain Classic" says: "In the east of Kaiming, there are Wu Peng, Wu Di, Wu Yang, Wu Lu, Wu Fan, and Wu Xiang. They are carrying corpses with yaoyao, and they are all separated by the medicine of immortality. The yaoyao have snake bodies and human faces, and they are killed by the ministers."
