A small glimmer that poured out from the gourd circled around Fang Zhou's fingertips, like a firefly with a life of its own.
The Night Mouse glanced over and explained, "This is Soul Power, also the reason those monsters can still move. Absorbing it can enhance your strength, but too much of it can have serious effects on your body, so I advise you not to touch it lightly."
Fang Zhou could only reabsorb the glimmer back into the gourd. Since it's a form of energy, keeping it might prove useful in the future, and it's not taking up any space anyway.
With nothing else to do, Fang Zhou looked through all the books on the Night Mouse's bookshelf, only to find that they were written in a language he couldn't understand. The books were also very fragile, with cracks appearing after a slight pinch.
The Night Mouse said softly, "Be careful. These are the few books I've found in Lorric City after many years. They could be considered the only books left by this ruined civilization."
