Adam is having a terrible time. To start the day off he died in a car accident. And that isn't even the most painful thing that happened to him. That would be merging with a strange crystal. After that he ended up stuck in an endless black void. He does eventually get rescued. But quickly realizes his soul has been put in the body of a fallen noble and his fate is to be little more than a breeding slave for the cultivation clan that purchased him. To top it all off his new body had been bedridden for weeks and he can barely get out of bed.
Not everything is terrible though. The crystal he merged with is called a dimensional originator. Using life and death energy he can create miniature universes. Given enough energy and time he could even create an entire universe. Also due to his talent for both cultivation and magic the clan that bought him has gathered an entire maid harem for him to have sex with once he recovers.
For a moment Adam thought things were looking up. Too bad the author finds things going horribly wrong far more entertaining.
Warning: If this fiction was a movie I'd rate it an R for violence, gore, and nudity.
