Traveling through time, he became Zhang Gui, a foreign relative of the Tianqi Dynasty. Because he didn’t want to be tortured to death by Li Zicheng in the future, he had to embark on the road of harming the powerful and bureaucratic officials of the Ming Dynasty.

The Yanguan scolded him for coercing the king and making disorderly manners.

The prince scolded him for being greedy.

The official hates him for being mean and cruel.

But helplessly, most of the Nine Frontiers are his lackeys, and even Jiu Qiansui is his godson, and the emperor can’t do anything about him.

Therefore, the Ming Dynasty was at the mercy of him.
