I been travel to gym so many times, but I find out those martial arts book is still only a few, so far I only found taichi, karate, taekwondo and aikido

where’s other martial arts book? the shaolin kung fu? krav maga? the five poisonous creatures? drunk boxing? capoeira or something else?

look like the only way to find other martial arts book is to trade with NPC? or if I can actually found one on somewhere?

Unless something changed recently, poisonous creatures don’t have books that grant them.

Some NPCs may be able to teach you martial arts, though.
