In the eighth year of Zhengtong, he transmigrates as Zhu Qizhen, just as he takes personal control of the court, and awakens the Son of Heaven System.
The System can cultivate martial arts on its own, but its power is closely tied to the fate of the Ming Dynasty.
Esen leads an army of two hundred thousand to Datong, threatening the capital.
Wang Zhen abuses his power, first claiming that only a band of petty thieves is causing trouble, then goading Zhu Qizhen into leading a punitive expedition himself.
To prevent history from repeating itself and avert the Tumu Crisis, Zhu Qizhen has Wang Zhen cut in half and resolves to wipe out the Oirat completely.
The entire court is shaken. Outside the palace gates, Yu Qian weeps in the rain: "Heaven has sent a sagely ruler. This is the Ming's good fortune."
