Yuan Ming played with the fire-red spirit stone, shaking his head regretfully.
The spirit stone, due to the differing spiritual powers contained within, could generally be divided into five main categories: gold, wood, water, fire, and earth. This particular spirit stone was obviously one of the fire attribute, and as he cultivated the Nine Elements Technique of the wood attribute, he couldn't use it to assist his practice by absorbing its spiritual power.
Yuan Ming put the spirit stone back into the small black bag and took out the book with great interest, eager to open it.
This book, having been stored in the small black bag, must not be an ordinary classic.
The pages of these books weren't made of paper but a soft white silk, which allowed for longer preservation than paper pages.
He flipped to the first page, and four large characters met his eyes: Black Wood Handbook.
