There was a lazy man named Fang Jianwu in Shaolin who was sleepy and gluttonous. He seemed to have no foundation in martial arts. He spent all his time fooling his master with a self-made book called "The Magic of Sleeping". No one knew that when he fell asleep, he went into a secret realm to practice hard. He practiced martial arts while sleeping, and his cultivation level skyrocketed. The head of the Tang Sect made a surprise visit to Shaolin and brought out the shocking secret of the appearance of the lost magic weapon Tianchandao, causing undercurrents in the world. Since then, the lazy young man has gone down the mountain with his master to practice, hiding his unique skills, and quietly emerging in troubled times.
