Liu Bowen beheaded Long Mai, but why did he choose to let Changbai Mountain go?

It is said that because Liu Bowen cut off seven Long Mai, the remaining stop pulse has been weakened. Liu Bowen felt that this move was against the sky, so he was reluctant to leave the last stop pulse, namely Long Mai in Changbai Mountain.

It turned out that Liu Bowen's beheading of Long Mai originated from a dream of Zhu Yuanzhang. Zhu Yuanzhang dreamed that there was light in the northeast, and Zhu Yuanzhang also said that he saw the breath of the son of heaven there. Originally, Zhu Yuanzhang was born at the grassroots level, and he was very afraid that someone would take his place, so he asked Liu Bowen to divine for himself.

And Liu Bowen is a very capable person, and he is also good at divination. Liu Bowen calculated that there might really be a dragon born in Northeast China, and the momentum was fierce, but Liu Bowen didn't tell Zhu Yuanzhang what he had calculated, just said he wanted to see it.

So when Liu Bowen arrived in the northeast, he observed that there were eight dragons fighting there, and Liu Bowen took the opportunity to slay seven, but the remaining one was also injured because of Liu Bowen's behavior, so Liu Bowen felt that this dragon was no longer a threat to Zhu Yuanzhang, and Liu Bowen also figured out that his descendants would assist this dragon, so he spared the last dragon.

Later historical development is often not much different from Liu Bowen's calculation. In the Jin Dynasty, eight tribes were at war, and only one Jurchen clan was left. So in the Qing Dynasty, the last Long Mai was regarded as his own Long Mai, namely Changbai Mountain, which was banned with others, especially the Han people.
