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 visited this place two days ago to discuss the reorganization of the Imperial Ruthenia Armed Forces. But now, he has come again to discuss the new military assets for the Army, Navy, Coast Guard, and Air Force.

He'll meet with the Chief of Staff of the Ruthenian Army along with military contractors that will submit a new design for their light and heavy tanks. Then with the Chief of Staff of the Ruthenian Navy and Coast Guard for surface warships and submarines. Lastly with the Chief of Staff of the Ruthenia Air Force for the new fighter, bomber, and reconnaissance aircraft.

Alexander has drawn new military designs straight out of the Cold War. He knew that with the inception of the CNC machine that he has been working on for months, Alexander would be able to make his drawing a reality.

In one of the meeting rooms of the General Staff Building. Alexander entered and was welcomed with salutations.
