You Are Asked to Teach Your Son to Cultivate Immortality, and You Teach Him Mathematics, Physics and Chemistry?

Special teacher Lin Fan travels through the world of martial arts and takes his nine-year-old son to participate in a family competition. While other parents took their children to do hard training, my son was forced to get involved in the reading material, and the arcane competition questions made him want to die. Other parents regard my father and me as martial arts useless people, but I insist on taking my son to the nine-year compulsory education to become educated. The Holy Land Prodigy's martial arts demonstration shocked the whole audience, but my son held a chemistry book in his hand: potassium nitrate (KNO₃) + sulfur (S) + charcoal (C) = black powder, and had no idea what his opponent was.
