MTL - A Fully-Leveled Bigshot Builds a Farm with Her Family After Transmigrating - Chapter 400 should do things

Usually when you possess a novel, you start in the city, but I fell into the forest.

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.

Humanity was finally recovering from the wave of an unknown Mana Apocalypse that had turned the world upside down.

A world where Science had married Magic. Advanced technology had mixed with magic spells.

Monsters took over the world and remarked earth's cities and countries as their kingdom. Half of humanity took the path of magic to survive, and half of humanity took the help of their advanced technology to survive. But what if humanity turns against humanity? The world split into two groups- The Science Users and The Mana Users

Hitori, who happens to be in the Mana Users group hates magic and spells. Saibai Hitori's passion, pleasure, and happiness lie in gaming. He unlocks the solo Cultivation System and the ability to cultivate in and outside the most popular game.

[The Emperor of the Apocalypse] is currently the best VRMMORGP open-world, kingdom-building survival game in the world. In this apocalyptic world, players try to clear dungeons marked on the map to mark that as their territory and eventually become the one and only Emperor of the Apocalypse.

In times of destruction, trusting someone will only destroy you. Players and guilds started attacking each other in the game. Guild Vs. Guild, Player Vs. Player, Player Vs. Environment, Realm vs. Realm. Everything is on, everything is going down.

Hitori's goal is to unravel the secret behind his parents' death and become the Emperor of the Apocalypse.

In a world where humans evolve and survive, only I cultivate and conquer.
