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?

An intelligence error caused the Third Fleet to face an ambush. In order to divert his enemies, the imperial admiral drove the starship alone into the meteorite band, and his spiritual power fell into a coma under heavy blows.
With the help of mystical powers, he began to experience reincarnation again and again to repair his spiritual power.
Therefore, after “death”, when he opened his eyes again, he became a blind and frail young master who’s parents both died and was about to be stripped of all his property by his uncle and aunt.

“Elysia, why are you always subtly asking about how Michael's doing?”“Oh? Do I? Maybe it's because he was the only Herrscher in our era who fought for humanity! He was both the First Herrscher and a human named Michael. Yes! That's definitely it!” Facing Mei's question, Ellie just offered a faint smile.“What about Mobius?”“Tch!” The green-haired little girl snorted dismissively, turning her head away.“Who else?” Mei covered her face.“Pardo?”“W-w-what! Kalpas is clearly very concerned about Boss Michael too!”“Get lost!”“Kevin?”“It's not entirely what you think. He has a much more important meaning to us—a family member we promised to walk towards the future with.”-----True Love Warrior Protagonist, Not very Mental stable Protagonist, Pessimistic Protagonist, Anti-Hero Protagonist, Crybaby Protagonist, Michael x Elysia.
