As the second emperor of the Tang Dynasty, Li Shimin laid a solid foundation for the prosperity of the Tang Dynasty. As an emperor who had experienced the battlefield, he was very good at fighting on horseback. However, it is precisely because of Li Shimin's long-term conquest and fatigue when he founded the Tang Dynasty that he had major physical problems when he reached middle age. According to the historical records, Li Shimin already had major problems with his health when he was more than 50 years old.

In order to be able to cure his body, he took countless drugs, but it never worked well. Therefore, soon after, Li Shimin fell ill and died. However, regarding Li Shimin's method of death, many people disagree very much, believing that he did not die of illness, so how did Li Shimin die?
In the beginning, Li Shimin was not a person who liked the way of immortality, and he had repeatedly told his subordinates that the way of immortality was just made up by Qin Shi Huang. And there are many examples to illustrate that the gods do not exist. In order to eliminate this idea, he also issued an edict to explain that human life expectancy is limited. From this point of view, Li Shimin is still a very clear emperor.
But these were all things that Li Shimin did in the early days, and he began to slowly develop this idea after he got old. In addition, due to the conquest of war in his youth, he was plagued by diseases in his later years when he was old, so Li Shimin began to gradually believe in the existence of immortality, so he was very fascinated by the art of immortality in his later years.
Li Shimin pinned all his hopes for his life on the elixirs of many foreign monks, and he trusted them very much, and as soon as the elixirs came out, he would immediately eat them without hesitation. It was this unconditional belief that made his health worse and worse, and eventually his illness worsened and he died. It is said that Li Shimin's death is too stupid, so it is rarely recorded in the history books.
