Longevity Clan Starts with the Patriarch’s Marriage - Chapter 756

The Third World War has been ended by the efforts of Kamijou Touma. With that, he vanished. With the Magic Side regrouping, the Sabbath for their followers has arrived.

In the headquarters of the Science Side, Academy City’s strongest Level 5 Esper Accelerator has washed his hands off the “Darkness.” Along with Last Order and Misaka Worst, his days pass by peacefully with no sign of GROUP.

Hamazura Shiage has formed a new ITEM with Kinuhata, Takitsubo and Mugino. Peace has come to the hands of the alumni who have “graduated” from Academy’s Dark Side at last… at least until a new evil “first year student” appears before them.

— This is a follow up to the popular Toaru Majutsu no Index light novel series, where Kamachi-Sensei has promised to deliver new premises and give a totally new flavor to the fights and plot developments

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?

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

What do you do when you're a loser who is suddenly called the saviour of the world!? You use it as an opportunity to take charge of your own life while picking up cute girls along the way!

Han Luo is just that kind of person, a perverted loser who is suddenly told he is the saviour of the world.

“what do you mean I'm the only one!? cant you see I'm a loser!?”

“If you want to kill me then you are going to have to work for it! My life isn't that cheap!”

Join Han Luo on his journey through the post-apocalypse!

[P.S. This is tagged Overpowered because I always wanted to create someone unbelievably strong. So Han is going to become one of the damn strongest people on this entire site - not just this story. But a good story needs growth, not just a quick power dump, so he'll be a bit pitiful at first, around chapters 1-15. So please bear with me till he gets back from his first time skip. After then, you'll be in for the ride of your lives]

Worked on it, so it's all good now.

Jiang Pengji: “Okay, System. No problem!”
Years later, she met the target by becoming the most prestigious woman (the Empress).
Jiang Pengji: “Well done, no?”
