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!!!

PS. Cover not mine, I just found it on google.

This is the story of an ignorant scum who pretends to be a scholar and goes to the world of Meiman to slaughter various scholars and bosses.

This is also a story about pretending to be a fool instead of pretending to be an idiot.

When the heaven will entrust a hero with a great responsibility, he must first take his nickname ‘Problem’, let his online name be ‘Jiancao’, and change his character to ‘conscience’.

Except for the protagonist’s surname Mei, everything else is fine.
