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?

My name is Charlemagne Theron, yes, that’s right, that’s the Theron you think of, and Ajan Lor’themar is my younger brother.

Don’t call me Daqiang, or I guarantee you will be beaten to three quarters to death. As a reliable time traveler, I will tell you responsibly, I…

“Charlemagne, what are you muttering, today is the day when my younger brother will inherit the position of Ranger General, you don’t want to be used by Cirvanas and Vereesa Hurry up when the arrow hits your nostril.”

“…Okay, my dear Alleria, here we go.”

When the two walked away holding hands, an imperceptible figure appeared on the spot.

“Brother, I wish you a happy Shura field.”

I am Charlemagne Theron, I have led the people to participate in the orc war, defeated the ancient gods and the second fool, I also fought against the Burning Legion, and I have made contributions to Azeroth , I bring salt for myself.

(PS: Don’t call me Daqiang, unless you want to grow an arrow from a certain key part behind you.)

Through a series of unexpected circumstances, she was pulled into the entertainment industry and became a female martial artist!

Female Fan: Our darling Wen is the most awesome! She’s even more handsome than a man!

Male Fan: The girls today are so domineering! To be able to throw away all of one’s shame, I want that feeling too!
