Why did Liu Bowen tell his family that when this book was put in a coffin, the emperor dared not touch my grave?

This book is Daming Law, which was made by Zhu Yuanzhang himself. There is a clear mention in it that all grave robbers will be executed in the end. Because Zhu Yuanzhang hated grave robbers at that time, he made special laws for this. After Liu Bowen's death, he put this book in his coffin in order to prevent Zhu Yuanzhang from settling accounts after the autumn.

During Zhu Yuanzhang's founding of the Ming Dynasty, Liu Bowen's contribution was so great that he could be regarded as a hero of the founding of the country. On weekdays, he was also highly valued by Zhu Yuanzhang, and later he and Li Shanchang revised Daming Law together. However, due to Zhu Yuanzhang's longer reign, he began to have doubts about Liu Bowen. After all, Liu Bowen's ability is too great, which has to make Zhu Yuanzhang timid to this person.

With the increase of age, Liu Bowen's health is getting worse and worse. He felt that his time was running out, so he chose a cemetery for himself in the suburbs in advance. However, when Hu Weiyong, who was jealous of him, learned about it, he told Zhu Yuanzhang that the cemetery chosen by Liu Bowen had the demeanor of an emperor, so he should be alert in advance. Zhu Yuanzhang was already suspicious and very angry. He deprived Liu Bowen of the right to use the land because it was about to be used by the imperial court, which made Liu Bowen very helpless. This made him begin to understand that Zhu Yuanzhang no longer trusted himself, so he resigned early and went home.

Later, Liu Bowen was very ill and time was running out. At the same time, he also knew that Zhu Yuanzhang would not let himself go easily, so he told his family before he died. When I die, I put this book Daming Law in my grave, so I won't be afraid of Zhu Yuanzhang touching my grave. At that time, when the family heard this, they all felt very puzzled, but they all did it anyway.

Sure enough, shortly after Liu Bowen's death, someone told Zhu Yuanzhang that the cemetery chosen by Liu Bowen was a treasure trove of geomantic omen, so he sent someone to dig his grave. However, before the coffin was opened, they found this book Daming Law, and a line was written in it:? Open the coffin and see the body die? . After Zhu Yuanzhang learned about it, he stopped digging graves.
