My Necromancer Class - Chapter 287: Clone Resurgence 2

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?

Missiles?
Modern medicines and equipment?
AC-130?
A nuke?
Challenger or Abrams or Leopard?

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

I thought that when I was reborn, I would work hard to be strong—however, I only started to struggle when fate came.

Once, I was weak and powerless, but the ninja world imprisoned me bit by bit like a cage.

Hinata, Konoha, Ninja World, one day I will break the cage/break free from the shackles and act recklessly. And those who were about to die – will also be reborn.

Until leaving a sentence – tell them, this is the last time I will fight for this decaying village.

“What if you never come back?”

“Then they will never return.”

“It’s like the color of your eyes determines that we can never be together. Even at the last moment of my life, all I see is blood and night—and the only thing, the white of your eyes.”

“White—it’s so good!”

Is it really good – the world of white eyes is just pale without a trace of color.
