Review Detail of Num_Oappai in Supreme Magus

Chap 429 He was mad because he couldn't showered for a week so why the f he learn magic for , He just needs to bring soap and make some water then shower . His whole mind only thought of himself and the bullshit purpose and did nothing to accomplish it .I see a lot of times that all his knowledge is for nothing and the author doesn't make the main character improve at all only makes he want to destroy the world.
