A smutty LitRPG with a futa lead.Long-running. Support me at Pat.treon.com/winterwhereof and receive early chapters.***Levels. Skills. Dungeons.As a nineteen year old living in modern society, these are terms Zoey is aware of. But had she ever expected to experience these videogame abstractions in the literal sense? To struggle through monster-infested realms, earning skills, casting spells, and acquiring rare and magical items?Obviously not.And more than the strange environment she finds herself in, Zoey contends with the bizarre reality of her class. Of being summoned by a sensual, perverted goddess who has gleefully bestowed a throbbing length between Zoey’s legs, then sent her off with a single unhelpful instruction: to save the world, and ascend to divinity while doing so.It’s all a bit much.But with so many cute girls to lay conquest to, and a new piece of equipment to help her along the way … well, things could be much, much worse.

After waking up in the body of the Young Master of the Luo family, he finds he has the knowledge of hundreds of games and Light Novels. However, he finds his Dantian is crippled, so he can’t practice cultivation! Luckily, he has the Upgrade system.

Killing Monsters, doing Quests, and even killing people- it’s just too easy. I don’t have any Martial Arts? I have hundreds of light novels, just let me level up so I can get this Main Character’s Martial Art! The only problem is: Should I follow the “This OP character cultivation” or should I follow “Another OP character cultivation”?! The tragedy!
