The most precious things in the world are priceless. Ordinary men tend to turn a blind eye to this fact. Apart from the treasured air, sunlight, and familial love, there is still one more thing that’s extremely valuable. It’s right beside you and can be easily obtained. But… I wonder whether you can see it?

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!
