What happened after Yuan Tiangang and Liu Bowen released the open-air machine?

In ancient times, people were superstitious because technology was not developed in all aspects. For some abnormal things, they are generally classified as strange things done by God, or they also believe that there are immortals in the world. So there was a kind of people who were very popular in ancient times, that is, fortune tellers. Most fortune tellers have no real skills, but in history, two people are very powerful. They can predict the future. These two people are Yuan Tiangang and Liu Bowen.

Yuan Tiangang was a figure in the Tang Dynasty. He was working with Li Shimin at that time. Later, at the age of 90, he felt that there was nothing he could do, so he pleaded with Emperor Taizong and asked him to go back to his hometown to support the elderly. So Emperor Taizong sent him home and made him the county magistrate of his hometown. Before leaving, one of his colleagues asked him, what kind of official will you be in the end? Yuan Tiangang said that I would die in April this summer. So his last official position was an ordinary county magistrate. Sure enough, Yuan Tiangang died in April of that summer. It can be said that he accurately calculated his own date of death.

Compared with Yuan Tiangang, Liu Bowen ended badly. After Zhu Yuanzhang became emperor, he had a premonition that Zhu Yuanzhang didn't trust these brothers who had made great contributions, so he took the initiative to resign and returned to his hometown to support the elderly. But he didn't expect Zhu Yuanzhang to worry about him, while Hu was playing tricks here. As a result, Zhu Yuanzhang was very suspicious of Liu Bowen, and Liu Bowen was forced to return to Beijing.

I wanted Zhu Yuanzhang to be completely at ease with him, but in the end Zhu Yuanzhang was still not at ease. After Liu Bowen fell ill, Hu brought a physician to treat him. As a result, Liu Bowen's illness did not abate, but worsened, and he soon died in his hometown.
