Level Up is getting me Undefeatable

Waking up in the Body of the young Master of the Luo Family with Knowdledge of more than hundres Games and Light Novels in a Different World should be a good Thing . But the Dantian is Crippled so cant Practice Cultivation ? This Brother have the Upgrade System its only killing Monsters , doing Quests and killing People , its just too easy for me . You mean i dont have any Martial Arts ? I have Hundreds of Light Novels , i just have to Level up so i can get Main Characters Martial Art . My Only Problem is should I follow the <> or should I <> ? What for a huge Problem !
