Why did Cheng call himself "the devil with the world"? Is there any allusion to this?

There are two versions of the play. The first is that Cheng's devil incarnate was given the title, and the second is that Cheng was called the devil incarnate when he proclaimed himself in Wagangzhai. In both novels and plays, we can find that Cheng came from a humble background, and later dreamed that the gods taught him martial arts, but because his mother woke him up, he only learned three axes. Cheng traveled around the world with three axes, and was finally reused and became one of the twenty-four outstanding figures in Lingyange. In the play, being a generous man can only handle three axes, so people nicknamed him the devil on earth, which depends on his personality.

There is one more thing in Wagangzhai. At this time, I took refuge in Cheng Wagangzhai. At that time, Wagangzhai established a new regime and became the leader of this regime. He called this country a monster. So everyone respects him as the incarnation of the devil. Of course, these are the images in the play. This is not the case in history. In history, Cheng not only came from a lower class family, but also learned three axes. After he became a famous family in history, his ancestors were all officials and bureaucrats' children, and they also had their own influence at the beginning. Cheng is good at dancing and carving, and his martial arts are also extremely good.

Later, Cheng Xian defected to Shi Biao. At that time, he was highly valued by Shi Biao, but he was cooperating with Wang at that time, but Shi Biao failed to fight with Wang. Later, Cheng was captured by Wang. Seeing that he was a talented man, Wang Shichong appointed him as a general. At first, Cheng accepted this, but later, he slowly discovered that Wang was not a wise man. So he defected to Li Shimin, and when he reached Li Shimin. Li Shimin also admired him very much. He made great contributions under his command, which played a great role in defeating Wang, Dou Jiande and others. Later, he competed with Li for the throne, while Cheng was appointed as the local secretariat. But Cheng said he would never go.

Later, Cheng participated in the change of Xuanwu Gate and helped win the throne. It is also one of the few military commanders who died well in history.
