Reincarnated as the Demon King's Son - Chapter 669 Unexpected Guest

A young man with an extraordinary mind is off on an exciting adventure when he mysteriously wakes up in the body of a feeble slave-guy in a different, rich in quirks world.

The main character, a selfish jerk, would use extreme means to achieve his goals. However, he never allows his base instincts to overrule his sense of decency. He always pays back both good and bad deeds.

Will his (terrible/excellent) mentality help him make a fresh start? Will he get through misfortunes and hardships of the new world?

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?

Cliche. Another monster progression story. That was probably what you thought when you read the title of my story. And, I can't lie, for the most part, it probably is.But, what else am I supposed to do when I've been thrusted into a world that could kill me in an instant? There's nothing to do but to progress, to devour and evolve. You would do the same too.Such is the basis of a monster.Such is the right of any living being.So that's what I did. I ate, I killed and I hoarded anything I could get my big limbs on. Friendship, allies and love? There used to be a little god calling himself “Heaven's Equal” who spouted of such things, before I ate him. The world went pretty quiet after that.Follow my story. Read for yourself how I evolved from a little monster in a lake I thought was the ocean, all the way into the Titan Of Destruction.What To Expect:- A relatively quick progression story- Ruthless, I mean - Fang Yuag levels - of ruthless protagonist.- A system? that grows stronger along with the protagonist- Big Monsters Duking It Out, with minimal humans/beastmen/elves, etc. . .focus. Basically, monsterverse without annoying ass humans ruining the show.- Did I mention that the protagonist was pretty evil?

The earth has entered the era of aura recovery, and human beings have started their supernatural awakening!

Jiangnan start awakening the strongest to spread the system, potion? Detoxification of small soybeans? Lucky cherries? In short supply!

The world’s top gods, richest men, beautiful school girls, popular anchors, goddess of high cold, and peak powers have all come to buy.

Jiang Nan: “I’m not interested in making billions of dollars! I just want to pit… Uh, my wish is for world peace!”
