Liu Bowen broke into the palace at night, really just to play chess with the emperor?

I believe many people have heard of Liu Bowen in the late Yuan Dynasty and early Ming Dynasty, and Liu Bowen is also a strange man in history. According to legend, Liu Bowen is knowledgeable, whether it is medical divination or astronomical mathematics, there will be no Liu Bowen. It was because of his talent that he became famous later. According to legend, after Liu Bowen assisted Zhu Yuanzhang to make great achievements, one night Liu Bowen entered the palace with a melon hammer that Zhu Yuanzhang gave to Liu Bowen, called Zhu Yuanzhang who was sleeping and told him that he had come to play chess with him. Liu Bowen certainly wouldn't go to play chess with Zhu Yuanzhang, but Liu Bowen suspected that someone would assassinate the emperor at night, so he went to protect Zhu Yuanzhang.

After Liu Bowen became famous, under the circumstances he knew, he thought that the Yuan Dynasty could not survive, so Liu Bowen began to look for someone worthy of his service. Later, Liu Bowen found Zhang Shicheng. After spending some time with Zhang Shicheng in Liu Bowen, he found that Zhang Shicheng was too narrow-minded and had no ambition, so Liu Bowen made an excuse to leave Zhang Shicheng. Later, he received many invitations from Zhu Yuanzhang, so Liu Bowen began to assist Zhu Yuanzhang, and later established the Ming Dynasty with Zhu Yuanzhang.

Zhu Yuanzhang attached great importance to Liu Bowen, not only because Liu Bowen was very loyal to Zhu Yuanzhang, but also because Liu Bowen knew astronomy above and geography below. Because Zhu Yuanzhang attached great importance to Liu Bowen, he later gave Liu Bowen a melon hammer, which gave Liu Bowen the power to treat hammers like people.

One night, Liu Bowen entered Zhu Yuanzhang's bedroom with a melon hammer and called Zhu Yuanzhang who was sleeping to play chess. When Zhu Yuanzhang saw Liu Bowen holding a melon hammer, he knew there must be something important, but Liu Bowen didn't say it, so they started playing chess. After a while, the soldiers came to report that the national treasury was on fire. And Zhu Yuanzhang began to worry, ready to command the fire, but Liu Bowen stopped him and asked Zhu Yuanzhang to let people go instead of him. As a result, this man was killed on the way there. Then Zhu Yuanzhang asked Liu Bowen how he knew there was an assassin. Liu Bowen said that he saw someone sending messages by homing pigeons during the day, and he knew something important had happened by watching the stars, so he broke into the emperor's bedroom at night.
