The five of us returned to the battlefield after we finished eating. While we ate, I flipped through the book Ming Hong had given me — it contained quite the myriad of useful hidden arts. While most were Basic level ones, there were some Intermediate ones as well and even an Advanced one.
Normally, an Advanced hidden art would've cost 3 AP to get, which could be spent on other useful skills. This was really a steal — back when I made the choice to form this deal with Ming Hong, I knew this would be worth it.
If I totaled up all the hidden arts in the book (around thirty in total), the overall value of it would be roughly equivalent to 41 AP — 20 Basic hidden arts, 9 Intermediate ones, and 1 Advanced one. If I perform further calculations… since I was Level 32 right now, 41 AP would take Level 42 to reach. I essentially just saved a whole ten levels' worth of AP.
