I have an Apocalypse City - Chapter 412: : Mutated Demon

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?

Please do check out my new novel “Rise of the Blood Sovereign”, which is participating in the fantasy carnival, I would appreciate it if you voted for it.

The year is 2060 and after decades of technological delay caused by mysterious events Earth and its inhabitants are about to face their greatest challenge yet. One, seemingly normal day everyone on Earth heard a voice.

{Earthlings, the time has come for change, please stay calm and wait for the terraforming process, everything will be explained during it}

Every human being was transported that fateful day, floating in space and watching the planet be transformed right in front of their eyes.

“I got a fcking stick as a reward, are you fcking kidding me?!”

Reign was there before most, as a human that defeated a monster before the terraforming he was titled a pioneer and got a chance to draw a lottery, but that did not end quite well.

Join our protagonist with his quirky group of friends as they fight and level up in this world that became a game, trying their best to win it and stop the destruction of Earth.

Will they be successful or will they fail?

What is the mysterious power hiding deep inside Reign?
