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?

He was the powerful and influential heir of B City, the merciless head of the commercial world, but the divorce papers made him lose his cool.

“Sign the divorce papers, daddy,” said the 5-year-old boy.

This man had the divorce papers thrown in his face by his wife six years ago, and was now being pushed by his own son to sign the papers.

“That would make you a single-parent child,” said Gu Juexi coldly.

“Mommy said unicorns don’t exist but men like you do,” the boy leered at his father and said.

Gu Juexi’s face fell. ‘That damned woman.’

“You haven’t signed the papers,” the boy reminded as the man left. As usual, the door shut in his face.

Good lord… Dad and mom are not getting a divorce and are giving him a baby brother? How worrying!
