Meng Nan, a teacher with a mysterious system, can tailor his teaching to each student's hidden attributes. His classes are extraordinary; students only need to take a good nap, and they subtly achieve significant improvements. Martial arts, alchemy, artifact crafting, talisman creation, music, chess, calligraphy, painting, and even flirting... whatever you can think of, Mr. Meng can teach it. A class of misfit students, under Mr. Meng's guidance, embarks on a magnificent journey of transformation. Mr. Meng often says, "Talent doesn't matter; what's most important is... having a good teacher!" "Geniuses? The failures I've taught can trample those so-called geniuses underfoot!"
