Life Plexus

Ace was carefully browsing through the first bookshelf, it was filled with different colored old books. Whether it was skill or technique, their names were imprinted on books' spines. 

He didn't find any finger base skill on the first shelf and move on to the next one. 

Grey was watching Finn's movements, while also monitoring that figure sitting in the restricted area. As for those six blue alchemists they weren't worth much. 

Half an hour pass and Ace has already checked eight bookshelves and still didn't find a single finger-based skill. Most of the skills were for fist, legs, or palm base, he already has some of them in his thief's space and even had a master-grade skill, so he wasn't interested in them. 

On the sixteenth bookshelf, Ace finally noticed something. 

'Stone Shatter Finger?' Ace looked at the green book with a hint of joy in his eyes. This was the first finger skill he found after searching for an hour.
