Uncle Baoya 1600 years ago, the mysterious ingredient of the elixir has not been cracked since it was unearthed, and it is kept secret.

The first person to pursue immortality should be Qin Shihuang. He sent Xu Fudong to look for the elixir of life, but he never saw it until he died. Later dynasties were obsessed with immortality, including Emperor Wu of the Han Dynasty. However, does the elixir really exist? What does it look like? Once upon a time, this was a mystery until 1965.

At that time, an Eastern Jin tomb was found in Xiangshan. According to the epitaph, archaeologists determined that the tomb owner was the female king of Wang Xizhi's family. After digging and sorting, the staff found a strange thing. They are about the size of rice grains, red and bright, with a diameter of 0.4~0.6 cm. Each weight is uneven. The big one is 0.468g, the small one is 0.275g, and the average weight is about 0.372g g. ..

According to statistics, there are more than 200 pieces of this stuff, some of which have turned into powder. When the tombs were opened, they were placed in a round lacquer box on the owner's head. After 1600 years, it is still well preserved. What is this?

In order to decipher the composition of these things, the experts took three tablets for testing. It is found that the main component is mercury sulfide, which is a highly toxic compound, in which the sulfur content is 13.0%, the mercury content is 60.9%, and the other 26. 1% cannot be detected. According to historical records, it was finally confirmed that this is the legendary elixir of life.

However, these elixirs of immortality have never been exhibited, and the Nanjing Museum displays replicas. Why?

According to cultural relics experts, the elixir of life is kept in an underground warehouse, guarded by a special person every day, and the temperature and humidity remain constant. How precious are they? Why can't you show it?

Experts explained that these pills are the earliest medicinal cultural relics discovered so far, which provided a material basis for studying the chemical composition and function of pills in the Eastern Jin Dynasty. Although Danwan is refined from a variety of minerals, after 1600 years, slight changes in temperature, humidity and light will cause certain lethality to it. The best way to keep it is to put it in the warehouse and don't touch it.

This explanation makes sense, but it always makes people wonder. Ask others, such as the number of elixirs collected and the proportion of various compounds. Experts say this is a secret and can't be revealed.
