Rebirth in One Piece as Deputy Captain - Chapter 535

The mid-level boss of my company’s AAA-game.

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.

It was a cold and lonely death on the battlefield despite the thousands of warriors around me and the beating sun shining upon my corpse.

In the year 431, I had died on the battlefield.

I was reincarnated into a new world, hoping my life would be better, but I ended up in a more miserable situation than before.

As the sickness began to eat the insides of my mother, a saving grace that would pull me out of the darkness, but into the abyss... had come.

From then on, amidst the wild flowers and the worship of the heroes, a brilliant god rose up.

In the world, I am the only one who has the name of a god!
