Reincarnated as an Imperial Prince
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? Expect some: Cold war era techs. Super battleship with advanced electronics, propulsion, and fire control systems? Helicopters? Missiles? Modern medicines and equipment? AC-130? A nuke? Challenger or Abrams or Leopard? F-4 Phantom or MIG-21? Colored TV's. Everything!!!

Entropy
Time passed like an eternity inside one of the many rooms of the Grand Kremlin Palace where Alexander was having a meeting with the Ambassadors of the Deutschland and Austrean Empire. And he was glad that it ended because the discussion turned roundabout to the point he decided to leave them with a promise they'll find out who caused the attack.
Though it wasn't their job in the first place, but since his technology is involved, the Ruthenia Empire will be obligated to take part in whatever investigation. After all, the head of state of the Empire is also the chief executive officer of the Imperial Dynamic Systems.
Alexander returned back to his room and he was glad that it was empty. He grunted as he sat in his office chair and dialed the telephone to call Kaiser Wilheim, who according to Sergei, has been demanding to speak to Alexander since then.
