A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

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.
