During the drought, Zhu Yuanzhang asked Liu Bowen what to do. Why did Liu Bowen say it would rain if one person was killed?

At that time, Liu Bowen had seen the sky at night and knew that it would rain in a few days. Moreover, at that time, he was going to kill a lawless official, Bing Lin, who happened to be a protege of Li Shanchang, so Liu Bowen would say that it would rain if a person killed Bing Lin.

Liu Bowen was a great contributor to Zhu Yuanzhang's establishment of the Ming Dynasty. He knows astronomy above and geography below. If anyone can compare with him in ancient times, it is estimated that Zhuge Liang was the only one in the Three Kingdoms period. But his advantage over Zhuge Liang is that he can tell fortune, and often his words will come true, so Zhu Yuanzhang was convinced of his words at that time.

After Zhu Yuanzhang established Daming Jiangshan, Liu Bowen's official position was actually not large, but this did not affect Liu Bowen's confidence in serving the country, so he would not let go of officials who violated the law and discipline for the people. Bing Lin is such an official. At that time, Liu Bowen had mastered the evidence of Bing Lin's violation of the law and intended to blame him, but Bing Lin was Li Shanchang's favorite pupil, so when Liu Bowen wanted to blame Li Bin, Li Shanchang came out and stopped him. This Li Shanchang is also the hero who helped Zhu Yuanzhang to pacify the world, and his relationship with Zhu Yuanzhang is much closer. His daughter-in-law is still a princess, so Zhu Yuanzhang always listens to Li Shanchang. Li Shanchang's favorite is cronyism, so most of the civil servants in the Qing Dynasty were his proteges. When Liu Bowen wanted to find out Lin Bing, Li Shanchang interceded for Bing Lin, and Zhu Yuanzhang was somewhat soft-hearted.

Just then, there was a great drought. Liu Bowen observed the astronomical phenomena and knew that it would rain in a few days, so he told Zhu Yuanzhang that it would rain as long as Bing Lin was killed. Liu Bowen was a fortuneteller, so Zhu Yuanzhang killed Bing Lin without hesitation.
