Undefeated Legend

Traveling to another world with an upgrade system and hundreds of novels, he became the good-for-nothing young master of the Luo family who raised horses. Can't practice if the Dantian is broken? I have an upgrade system. To me, breakthrough means just killing monsters, doing tasks, and occasionally killing people. It's so easy! No skills? I have hundreds of novels, and as long as I upgrade, I can get the skills of the protagonists in those novels. What worries me is whether to choose the star skills, the laws of the earth, or the secret code of shadows? So irritable! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
