But there's a twist: his cultivation level reads 9999, and he possesses a mysterious personal dimension. Armed with modern knowledge and absurd power hidden beneath a 'trash' reputation, he'll shock the cultivation world, rebuild his crumbling Xuan Tian Sect from the ground up, and win the hearts of stunning fairy maidens who never saw him coming.
