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

St. Petersburg, Ruthenia Empire. At the Winter Palace.

Alexander was on the call with someone on the telephone.

"Your Majesty, we have good news. The Navstar satellites that we have been working on since you proposed it is good for launch this April. There will be a total of five satellite launches in that month all across our spaceports."

"Hoh?" Alexander sang, "That's good then. I've been waiting for the report about the development of Navstar. Not to mention, five satellites! That's an incredible number, I'm assuming that you and your team have been working hard perfecting the craft."

"Yes, Your Majesty. Our team has been working tirelessly to make your vision in space be realized. But Your Majesty, if I may ask, we need 24 satellites orbiting the earth to make full use of the global positioning system capabilities to be utilized by our military, is five satellites going to make a difference in the field of navigation?" Wegener raised a question.
