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? Or will he succumb into a conspiracy lurking within the country's borders?

Reincarnated as an Imperial Prince

Alexander's adorable daughter, Anya, rushed up to him in glee. He immediately went to one knee and received his daily dose of a warm hug.

"Anya, what did I tell you about staying inside the Palace? The outside is very cold you know, you might catch a cold from it and it would be problematic to me."

"Sorry, papa, I'm just excited to see you. That's why I'm waiting for you outside," she said gleefully.

"You little…" Alexander pinched her cheek gently with one hand and ruffled her hair lightly with the other. "Well, it doesn't matter anyways. Even if you get sick, your papa is there to save you. But you must know that prevention is better than...?"

"Cure!" Anya finished as she grinned and nodded.

"Yes, yes, that's my girl," Alexander smiled affectionately as he stroked her hair once more. "Now, where is mama? Does she know that you are outside?"
