My Monster Fuses Everything - Chapter 639 - 415 Counterattack Begins_2

The second moon marked the beginning of a revolutionary change.

With the emergence of monsters and dungeons in modern society, and the ability users who fight against them, the world faces a shift in its paradigm.

It heralds the advent of a new energy source and the decline of traditional occupations.

Common sense thus becomes warped and imagination becomes reality.

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.

As a useless spoiled wild child, Bai YiHan finally brought about the end of his family, chased away the one he loved and caused his own death. After rebirth, he decides to cleanse himself and work hard at being a good child. But a lot of things don’t seem to be as he expected…

Bai Pa + Bai Ma: My son’s so obedient. Someone must be bullying him. This cannot be forgiven!

Bai Big Bro + Bai Big Sis: If my little brother’s sensibility comes from his suffering, then I’d rather he be a spoiled brat forever!

Mu JingYuan: If HanHan hits you, you must accept it. Yet you dodged…The wind’s changing. Someone should be bankrupt to make HanHan smile.

Bai YiHan: …I was so wild in my past life. Your involvement are undeniable!

This story is speculative, speculative, speculative. Important matters must be said thrice. Everything is about speculative time-traveling.
