Xu Maogong, who calculated that McCullough could live 73 years old? Why did McCullough die at the age of 23?

Because Luo Cheng was calculated to be 73 years old at that time, this was his theoretical life span, and Luo Cheng's actual life span was not calculated, so Luo died at the age of 23. First of all, mccullough killed many innocent people during the war with his father. Mccullough's life span was shortened by ten years because he didn't dissuade his father. Although he is wronged, God has the virtue of a good life. McCullough had no sympathy at that time, and it was understandable to be shortened.

And McCullough agreed to exchange the family achievement method with his half-brother, but McCullough secretly left the last formula of the achievement method, for fear that his brother would be killed by him later, and he was so dishonest to his brother that his life span was shortened for ten years. Later, he and his brother who grew up together made their own decisions. They met on the battlefield and witnessed his brother die in front of them, which shortened the life span of people without feelings by ten years.

Secondly, McCullough had a good personal relationship with Li Shimin and had saved Li Shimin. Once, two people thought it was very interesting, so they made an appointment to drink by the lake. After both of them were drunk, Luo Chenggong rode on a horse and asked Li Shimin to help him lead the horse. We all know that Li Shimin was a very talented emperor. McCullough ordered Li Shimin to take his horse and do such a disrespectful thing. He must shorten his life by ten years.

Finally, Luo Jin cheated a woman's feelings during the siege and set her on fire after the wedding. Such a heartless person will definitely live ten years less. We can see from here that Xu Maogong's fortune-telling is actually very accurate, but because McCullough has done so many wrong things, he will only live to be 23 years old.
