I Help A NPC Become The Legendary Witch - Chapter 749 - : Black Lord, Please Punish Miss Liz

I accidentally changed the whole world, the resurrection of the dead, genetic variation, recovery of the qi, mountain and seas reborn, land and seas expanded and evil spirits have started to appear.

Ghosts are now commonplace. Some people now have three heads and six arms. Some people have obtained martial arts techniques and ordinary people are now just cannon fodder.

Fortunately, I have acquired an ability which can make various items mutate.

books into martial arts or cultivation manuals,

fruits into precious treasures of heaven and earth or poison that you can only imagine and…

weapons, that can split the earth or gain sentience!

have you heard of it?

If you turn on the music player in the dead of night, put on headphones, hide your head in the quilt, and listen to the looped single repeatedly.

Fall asleep after looping forty-four times. If you are unlucky and open your eyes again, you will no longer be lying on your own bed, but will enter a strange space that is completely isolated from reality.

That space… On the surface, it looks like the places we usually see, such as our bedroom, living room at home, underground garage, bathroom, basketball court, construction site, etc. But if you look closely, you will find that it is different. …Everything is different.

====

This is the experience of an ordinary person who, after acquiring superpowers, transforms and grows step by step in a blind corner, reaching the ultimate level.

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?

Everything!!!

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

I didn’t know this was a world inside a game. And I didn’t know my master was a mid-boss. “No way… wasn’t she supposed to self-destruct because of her personality?!” …I’m sorry.
