Ye Qiu transmigrated to a world of barren wastelands. He obtained the 10,000 Fold Return System.

I woke up naked and all alone in a summoning circle, the only clue to my past is a demon summoning book and the hazy memories of a world very different from the one I find myself in now. I should probably be more concerned with the changes that have befallen me but I can't help but be excited to explore this new world with the new lovers I've found. After all, I'm apparently the Origin of Succubi, my actions will shape my new race in this world and all I know for sure is that I'm horny as hell.I update twice a week on Sundays and Wednesdays!Note: This novel contains a rape scene early on in chapter 8, this is not a frequent occurrence and it is not glorified or treated lightly. This is an event that affects the protagonist though so there are occasional references and allusions to the event throughout the series. The novel is loosely a genderbender but the Trans tag is for a character other than the protagonist.The series primarily features anthropomorphic characters including the protagonist which may be a turn off to some readers. The references to things like snouts and muzzles happen relatively rarely though, so you may be able to picture the characters as monster girls instead.

The world experienced a cataclysmic change, and countless spatial gateways appeared out of thin air.

Exotic beasts of all shapes and sizes swarmed out of those aforementioned spatial gateways, forcing the humans to face the crucial moment for their survival.

In order to search for a chance at survival, brave warriors from the army and scientific researchers risked their lives and entered the world beyond the spatial gateways. To their surprise, they discovered that there was a chance of obtaining beast cards by killing these exotic beasts in their world.

Those with extraordinary spiritual strength are able to utilize the beast cards, perhaps transforming the cards into the beasts’ combat bodies while they were still alive, or transforming them into weapons or defensive gears, or…

A new occupation came into existence following the changes, known as beastmasters.

A transcender with two souls fused into one found himself in this magnificent new world full of waves, rising step by step as he ascends into the seat of a godly beastmaster.
