1, many people know that the so-called elixir of life is basically a pill refined by the alchemist. It is not a real elixir of life in fantasy novel, but a poison containing mercury. People didn't realize this problem at that time. As a result, many people who want to pursue immortality did not get immortality after eating this elixir, and in fact it is impossible to get immortality. It is to let those who pursue immortality "die" prematurely. Modern knowledge tells people that unless they want to "die", this elixir refined by alchemists must not be eaten.
Second, the average life expectancy of ancient people was very low, especially during the Warring States period, about 20 to 30 years old. On the one hand, the ancient medical level was low and the mortality rate was too high. In addition, the war took the lives of young people, resulting in a very low average life expectancy. Even in the later years of relative prosperity and peace, the average life expectancy was only 30 to 40 years old. Therefore, people yearn for longevity. Now people's average life expectancy has been greatly improved, and their knowledge level has also been greatly improved. Of course, they dare not eat that fake so-called elixir, and it is unnecessary.
Third, it's interesting. It is said that the elixir that Qin Shihuang is looking for is "Tai Sui", that is, "Ganoderma lucidum". Compendium of Materia Medica says that it is a "creature with a head and a tail", and even more, Ge Hong of the Eastern Jin Dynasty said that it "makes people fit and live forever" in Bao Puzi. This myxomycete complex can grow after being cut, and it has strong vitality, but it is really a good thing to keep fit. But this thing is very expensive, too expensive. Eating Pleurotus eryngii is not worth it. So whoever found it probably didn't dare to eat it, and he couldn't bear to eat it. He had to sell it.
To sum up, modern people generally dare not eat the elixir pursued by Qin Shihuang, fearing that they may die and be "poisoned" by the elixir; Either you can basically know that this thing doesn't exist at all, and no one dares to eat the so-called longevity medicine you just smashed; Either I met "Tai Sui" and didn't dare to eat. I have to consider selling money quickly.
