Because Ming Guangzong was terminally ill and his life was dying. When he saw that the red pill was a dead horse, he swallowed it without delving into it. Ming Guangzong ascended the throne in his forties. During his reign, Zheng Guifei from the harem presented him with more than a dozen beautiful women. Ming Guangzong couldn't help it at first sight. He is lucky day and night, immersed in the gentle village of beautiful women.

Not long after, because of too much sexual intercourse, Ming Guangzong's body was getting worse every day, and he could barely support it at first. Later, he couldn't move normally and couldn't afford to get sick. At this time, a eunuch who was also a long-term imperial pharmacy in the palace had a bad idea, saying that the emperor had accumulated too many toxins in his body and could not be excreted, so his condition had been deteriorating, and he was given drugs to clear away heat and relieve constipation. As a result, Ming Guangzong ran dozens of times to the toilet overnight, and people completely collapsed.

Just as Ming Guangzong was dying, another man named Li had a brainwave, claiming that he met a fairy in Emei Mountain and gave him a red pill, which could cure all diseases and live forever.

Ancient emperors had always been superstitious, and most of them tried to refine the elixir of life during their reign. In addition, Ming Guangzong knows that time is running out now, so he might as well try one. So he took two red pills in succession and died suddenly in a few days. The so-called "immortal red pill" is mainly composed of the menstrual blood of women, the crystallization of children's urine, human milk, cinnabar and so on. In fact, there are a lot of bacteria and viruses in the world. People who are weak and sick will only aggravate their illness and accelerate their death.

Therefore, it is ironic to think that Ming Guangzong was poisoned by this kind of red pill after only one month as emperor.
