The Apocalyptic Divine Skill Journey

After the cataclysm, Earth entered an age of spiritual energy, and martial arts rose above all else as the strongest means of combat.

While countless people fought tooth and nail over fragments of a third-rate martial arts manual, the protagonist was wondering:

“The Six Meridians Divine Sword. Which six fingers should I train?”

“Using one finger on each hand would be stupid. Am I supposed to poke people with my thumbs? How lame is that?”

“Hmm, the index finger's good. It'd feel great to poke someone with it, and it looks imposing. The middle finger's great too: just raise it and you're showing pure disdain and contempt. The pinky isn't bad either. Hook it and you can take someone's head. Perfect!”

“Right, I've decided. I'll train the index, middle, and pinky fingers on both hands!”

P.S. Be warned before you dive in: this book wears a wuxia skin, but don't take any of the martial arts seriously. If you do, you've already lost.
