Hi, class.Welecome to Magic history class.Today ,we will learn about Alchemy. Long time ago,Alchemy was famous in China.According to resear,Alchemy originated from the Zhou Dynasty(1046 B.C.-256 B.C.).In these centuries,never dying is one of people's biggest dreams,so people wanted to make “potions” to help them achieve their dream .But it is a pity that in those days,the magic was not yet mature,so people could only mix all kinds of strange materials together,after treatment,and throw into a large furnace,“potions”were ready. Those strange materials included:all kinds of plants,animal bones,minerals,metals and so on.Amazingly,those materials could even include gold and mercury!This sounds crazy,but it's true.Mercury and gold are not easily eroded,so people believe that through this way, they can also get this ability. Maybe you can't understand .Right,in fact, many people died because of ate these pills,such as Emperor Sima Pi of the Eastern Jin Dynasty. With the passage of time,magic became mature and mature.Ancient Chinese wizards were clearly good at making magic potions.There was a wizards named Xiwang Mu gave the potion she made to a muggle named Hou Yi who had helped her before.Later, someone wanted to steal this potion. In order to protect it, Hou Yi's wife drank the potion, gained the ability to live forever, and flew to the moon. For muggles,“Alchemy”was beginning to become correct,too.Muggles have slowly found many materials that can truly treat diseases.During this process,They also happened to have invented gunpower,this is of great help to their lives. Any subject needs efforts of many people to become mature, each of us should think more about questions to make the world become better and better.
