There are so many emperors who died in alchemy, why are there still emperors obsessed with alchemy?

Ancient emperors could control people's life and death. When he became emperor, all the talents in the world also belonged to the emperor. The emperor can be said to be the most powerful person, and he can have whatever he wants, but the emperor is also a human being, not a fairy, and will die one day. Everyone has greed, and no one is willing to give up the aura of the emperor. Everyone wants to have these forever, so many people are looking for ways to live forever.

Although an alchemist may eat the dead at the age of 20, after all, there is a chance of immortality, and the ancients will think that immortals may be eaten by alchemists, so there will be immortals. If they can be immortals, they will be immortal, even if they don't live long. So I'm obsessed with alchemy.

Some people may know that alchemy is not good, but they will still persuade the emperor to do so, hoping that the emperor will die so that they can master the complete works. Generally, people with great power are trusted by the emperor. These people persuaded the emperor, and the emperor would be more convinced, and then he would go further and further on the road of alchemy.
