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?

Miss Xiangfu: Cheng Shenyi is a prodigy, but he has a noble character and is not interested in fame and fortune. I respect him and love him, even if I have no relationship with him, I should ask the prince’s cousin to give him a birth.

Ten Miles of Spring Breeze Hua Kui Lady: Except for the three feet of snow on your body, who in the world is matched with white clothes? In that court, were they okay with you?
