The protagonist's name is Shen Du. He was originally the most useless casual cultivator in the world of cultivation. He had mixed spiritual roots and poor qualifications. He had only been able to build a foundation after practicing for thirty years. He was ridiculed by his peers as "the old monster who has been building a foundation for ten thousand years." On the surface, he is lazy and easy-going, smiling at everyone, but in fact, he is thoughtful, evil and vengeful, and is good at deceiving people with his sharp tongue. Due to an accident, he was hit by a heavenly catastrophe, and his soul traveled to the body of a down-and-out scholar in the mortal world, becoming a poor scholar that no one cared about in Qingzhou City. He originally wanted to lie down and wait to die as a mortal, but he found that he could see through the hidden immortals in the mortal world at a glance - those masters with immortal demeanor, the old man selling candied haws on the roadside, and even the oiran in the brothel, all had a "halo of cultivation" in his eyes. Shen Du's growth arc is from "slicing salted fish" to "being forced to stir up troubles". He didn't want to meddle in other people's business, but he always exposed the disguise of the immortals because of his bad words. He was hunted down, accepted as a disciple, and forced to have destiny. In the end, he returned from the mortal world all the way back to the cultivation world, and became known to both worlds as "the mortal who is the best at deceiving the immortals."
