You don't want your secret to be revealed by others, right? - Chapter 416 - 27, Nine-colored Beast Breath

Ten Years after the Descent to Earth of a Radical And All-Knowing System Called Arkadia, Life has changed in ways we could only surmise given we lived in a comic book. People with superpowers, Monsters, Heroes and Villains, Hell, there were even Other races coming out of the woodwork like Elves and such. Still, it wasn’t until The Extraterrestrials Invaded that things went from bad to worse.Yet, as if hope truly existed, 5000 of us Earthlings were given the opportunity to Head back into the past, only we didn’t know at the time there was a cost for doing so. By sending us back, the Descent Clock began, as Arkadia was pushed 10000 years into the Future, and it was up to us Returners to get things set back on course by changing the past to mold the Future.And I, being a boogieman of a Villian in what I dubbed the Origin Timeline, have come up with thousands of potential ways to affect my new life, like stealing popular franchises to earn some long-term funds or….hunting down notorious Serial Kills and Solving long-standing Cold cases I had been curious about since I was a teenager.

An otaku with a hobby of masturbating was reincarnated as the son of a great mage.

As soon as he was born in this life, he vowed with a goal of embracing women till his death.

That said, when he became 20 years old, the Demon Lord which was sealed by his ancestors revived, and now it is his role to seal it once again.

And that demon lord is sealed in a tower dungeon that is rumored to be impossible to capture.

However, by an unexpected coincidence, he had found out that the Demon Lord is also one of him, a kindred spirit from within,

so he joined her instead and filled several traps in the tower dungeon, and thus they enjoyed a s*x spree with all the women coming over!

This book is also known as ’Because I Spoiled My Wife Too Much, I Was Forced to Become an Invincible Antagonist.’ Gu Lan transcended into a fantasy novel as a supporting scholar. He even gained a beautiful and delicate wife. He had initially planned to live quietly, avoiding all kinds of trouble based on the original plot, and spending his life peacefully with his beloved wife. But he happened to acquire the ’Read and Copy Books System’! As long as he read and copied books, he could extract cultivation, becoming a saint and even a deity! Due to being overly invincible, Gu Lan casually crushed major antagonists when he ventured outside. Sons and daughters of fortune were eager to acknowledge him! As his strength skyrocketed, his career went surprisingly smoothly as well. One day, Gu Lan, the top scholar from the high school examination, entered the palace and saw a stunning empress behind the curtain, who looked very familiar! “Babe?” “Darling, don’t you not recognize me when I put on the dragon robe?” “...” From that day on, the whole world knew about this extraordinary couple. The original male protagonist: “He’s already a Heavenly Emperor, and I’m just at the third stage of martial power. How am I going to compete?”

Chu Mu Yun relied on his story of 《Demon Realm》 to become a one-hit wonder in JJWXC, but the him who had written seven mental cases to abuse seven mental cases to death would never have expected that he himself would transmigrate into this shitty novel!
What the hell is this system on the bracelet?
And what the hell is this either propose to seven men, or suffer the taste of a tragic death experience under the hands of these seven people?
I just wanted to write a novel to satisfy my bad interests, who would actually want to get tangled up with a bunch of mad dog sad*st crazies?
