Mana
"Listen carefully now Xu Ming. All around us, in the air, in the sky, even in the stars there exists an energy permeating all throughout the universe. This energy we call Cosmic energy, or you can imagine it like the 'Mana' that plagued all of the ancient novels in our own Human history. It is using this Cosmic energy that we are able to do the things we do. Immortals have been created in our race due to this one simple but very complex energy."
Xu Ming listened to his master speak his wise teachings as he was excited to finally be given the opportunity to cultivate like the rest of humanity when they reach the minimum age requirements.
He had just turned 16 the day before, the age where one begins cultivation, and now his father had hired a great cultivation scholar to teach him the basics of cultivation as well as to watch over him when he establishes his foundation lest he makes any life threatening mistakes.
