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?

Ascension of the Hollow Star

Upon opening his eyes, Muyang realized that he found himself in Dragon Ball’s world filled with dangerous people like Vegeta, Frieza, Cell, Majin Buu.

However, decades later.

“Captain Ginyu, let’s run away, we are no match for him!”

Jeice looked back in panic.

“Lord Frieza, the demon has caught up again.”

“He even destroyed our home planet.”

“This bastard!”

Frieza looked at Muyang with bloodshot eyes filled with anger, but sadly, there’s nothing he can do, even he’s no match for Muyang.

“Come on, show me what you can do.”

It was a life without regret. My parents were in good health, and I wasn’t homey enough for me to combine my studies and part-time jobs.
