After transmigrating to the cultivation world, Chun Xiu gets tricked by an old man after stealing a bun, but ends up with a peerless cultivation manual. The problem is, he's completely illiterate, so he can only practice by guessing from the pictures. By sheer accident, he reverses the cultivation method and develops a body full of demonic energy, prompting the entire continent to hunt him down as a peerless demon cultivator!
After finally being shoved into a sect as its Holy Son by the old man, Chun Xiu heads to the Scripture Pavilion to keep "reading the pictures." He somehow turns every righteous cultivation technique into an ultimate demonic art, leaving countless big shots stunned.
Everyone says the Holy Son is unfathomable and has heaven-defying comprehension. Only Chun Xiu is screaming inwardly, "Stop praising me! I really can't read!"
