I think the main reasons why Chuang Wang Li Zicheng wanted to do everything possible to destroy the Feng Shui treasure land when he started the uprising are as follows. First, this Feng Shui treasure land is the tomb of Zhu Yuanzhang’s parents; secondly, he wanted to destroy this Feng Shui treasure land. It will strengthen the morale of the army and conquer the hearts of the people.
1. This geomantic treasure is the mausoleum of Zhu Yuanzhang’s parents
This geomantic treasure is the mausoleum of Zhu Yuanzhang’s parents. There was a legend at that time that the reason Zhu Yuanzhang was able to become emperor and establish the Ming Dynasty was because his parents' tomb was built on the dragon's veins. It is said that Zhu Yuanzhang became emperor entirely because of this dragon vein, so Li Zicheng would plan to destroy this place if he wanted to destroy the Ming Dynasty. I think the statement that the tombs of Zhu Yuanzhang's parents were built on dragon veins is completely a boast of the Zhu family.
To say that one’s own dragon vein is built on will first consolidate one’s rule and make others more convinced of oneself. It will also cast a layer of mystery over his rule, and the people will even think that this person is destined to be the emperor by God. This shows that the Zhu family is really good at playing with people's hearts and is very wise. So I think it would be faster and more convenient for Li Zicheng to destroy the tombs of Zhu Yuanzhang's parents than to find a Feng Shui treasure land for his parents.
2. Destroying this geomantic treasure land will shake the morale of the army and win over the people
Destroying the mausoleum of Zhu Yuanzhang’s parents will definitely shake the morale of the army. The soldiers in the army will think that if we can destroy the foundation of Lao Zhu's family, we can destroy the Ming Dynasty. Such a move increased the soldiers' fighting enthusiasm, making Li Zicheng's army more capable of fighting.
After the common people know that Li Zicheng destroyed Zhu Yuanzhang's family's feng shui treasure land, they may think that Li Zicheng is a person sent by God to establish the next dynasty, so they will win over some people's hearts. I think Li Zicheng is also a very wise person and knows how to control people's hearts. But it does not rule out that Li Zicheng simply wanted to destroy this geomantic treasure.
