Before he died, the man asked his son to give a book to Zhu Yuanzhang and told him not to peek. Who is this man?

This man is Liu Bowen with superior wisdom. Before he died, he gave Zhu Yuanzhang a gobbledygook. His son was not allowed to read, because he didn't want Zhu Yuanzhang to think that his son could explore the secret, so he became suspicious of them. This book is actually an account of Zhu Yuanzhang by Liu Bowen, so as to end Zhu Yuanzhang's doubts about their Liu family.

Liu Bowen is very clever. When he lived in seclusion in the mountains, he had communication and contact with many other people, so Zhu Yuanzhang always wanted him to help. Liu Bowen still has his own ideas. Before the Yuan Dynasty, Liu Bowen lived in seclusion in the mountains, and Zhu Yuanzhang invited him out of the mountains. Liu Bowen probably agreed to help Zhu Yuanzhang because he could change from a farmer to an emperor.

After Zhu Yuanzhang proclaimed himself emperor, he was very suspicious and always doubted the loyalty of those who fought alongside him. Because Zhu Yuanzhang changed from a farmer to an emperor, he cherished this position and power even more. So the first thing he did after he proclaimed himself emperor was to eliminate those hidden threats. Then the people who fight alongside him are all capable people, and they are most likely to rebel. Therefore, Zhu Yuanzhang began to distrust Liu Bowen.

Zhu Yuanzhang always thought that Liu Bowen could know the secret, because Liu Bowen always thought what he thought, just like a worm in his stomach. As an emperor, he must not let others know what he is thinking, which would be very dangerous, so Zhu Yuanzhang did not allow such people to exist, so he moved his heart.

Later, when Liu Bowen was ill, Zhu Yuanzhang sent a doctor to visit him. As a result, he became more ill. Liu Bowen understood that Zhu Yuanzhang wanted to kill him. Liu Bowen gave his son the gobbledygook before he died, and asked him to give it to Zhu Yuanzhang, which means that my ability to investigate secrets is here. My descendants don't know that they are innocent, so you don't have to doubt it, so he must give this book to Zhu Yuanzhang in order to protect his descendants.
