Invincible in the Wuxia World, Starting by Winning Wang Yuyan's Heart

Shen Li has transmigrated into the body of a pampered, illegitimate son surrounded by enemies. His own brother tries to kill him, and his father favors the other children to an extreme. He’s ready to curse them all out! Luckily, he awakens a sign-in System in this comprehensive martial arts world. [Congratulations, Host, for signing in at Lingyan Valley. You have obtained the Nine Yang Divine Skill.] Great, great! Now give me an unlimited energy bar. [Congratulations, Host, for signing in at the Wanhua Pavilion. You have obtained Awei’s Seventy-Two Techniques.] A skill that can only be used in bed? [Congratulations, Host, for signing in at Brightness Peak. You have obtained the divine weapon, the Heaven Sword and Dragon Saber.] Now that’s what I’m talking about. I’ve got a hard weapon too! Over the course of ten years, Shen Li has traveled nearly the entire world. That illegitimate son from back then has long since become invincible!
