Dragon Slaying Emperor

This is the story of a high school graduate in another world, an era where strength reigns supreme. He learns a technique that evolves by devouring the primordial spirits of Magical Beasts, and he can also refine Elixir Pills by devouring strange fires. But most importantly, he can devour the primordial spirits of Eastern divine dragons: the Azure Dragon, White Dragon, Black Dragon, Golden Dragon, Yellow Dragon... Want to devour a divine beast? Fine, but you'll have to start with a wild chicken! He never wanted to become so powerful, only wishing to live a honeymoon-like life with his Little Junior Sister at the sect. He never wanted to meet so many beautiful women, but when his luck explodes, he can't fend off the romantic fortunes that come his way.
