Ask the great god for help in alchemy.

Alchemy is an ancient alchemy to refine Dan medicine for "immortality". This alchemy originated in China long ago. According to History of Han Liu Xiangchuan, Liu An (179- 122), the king of Huainan, said in his Book of Hongbao Secret Garden in Pillow that Zou Yan was in the Warring States Period (about 305 BC), but this party has not been handed down, and Liu An's book has long been lost. Now it is impossible to find out what it is. However, in the Warring States Policy, there is a record of the alchemist asking Jing Wang Xian for the "fairy medicine", while in the Historical Records, the story of Qin Shihuang asking for the "fairy medicine" and sending the alchemist Xu (Fu) to lead thousands of boys to the sea to ask for the "fairy" is very detailed, which shows that China's alchemy has indeed begun to sprout in the pre-Qin period. The Emperor of the Western Han Dynasty (BC 156- 87) sought immortality and medicine on a larger scale, adopted Fang Shili's suggestion, and set up an alchemy furnace in his palace to make alchemy himself. From then on, the wind of alchemy began to prevail in the feudal ruling class and lasted for a long time until after the Song and Yuan Dynasties. Therefore, there were many alchemists who refined alchemy and mercury in the past dynasties, which is what we call alchemists today. China ancient alchemy methods can be divided into fire method and water method. The so-called pyrometallurgical method is mainly anhydrous heating method with metallurgical properties. Wei Boyang, an alchemist in the Eastern Han Dynasty, said in the Book of Changes that he had 600 fires at that time, which was about this kind of fire method. However, this book has long been lost, and the content is no longer there. According to Jin's Inner Chapter of Bao Puzi and his later alchemy works, the fire method generally includes satin (heating at high temperature for a long time), refining (heating dry matter), baking (local baking), melting (melting), pumping (distillation), flying (also called sublimation) and volts (heating denatures drugs). The earliest research material of alchemy may be cinnabar, that is, red mercury sulfide, which is studied by fire method. Once heated, red mercuric sulfide will be decomposed into mercury (mercury), and mercury and sulfur will combine to form black mercuric sulfide, which will be sublimated by heating, and the original state of red mercuric sulfide will be restored. The generated mercury is a metallic substance, but it is in a liquid state. It flows in a circle and is volatile, which is different from ordinary substances. Hehe, I found so much for the time being. I hope you can use it.
