Sigh, it didn't work.
Soon, after minutes of pondering/delving into the cultivation technique... Leo couldn't help but utter a sigh of helplessness upon feeling that his mastery of the cultivation technique hadn't increased a bit.
Although he could feel that his mind seemed to become much more clearer than before, it was still not to the point where he could gain enlightenment in the shortest time possible based on the description of the stone.
Sigh...
Opening his eyes, Leo again examined the little stone in his hand, contemplating how he could use it.
"System? Any idea how could I use it?"
Leo asks within his mind, but only to hear the usual silence within him.
...
"Sigh, never mind, I should just continue practicing the Mana/Qi thread...
Growl (Sound of a hungry stomach.)
"However, before that, I should eat first!"
