As for "Magic Rune Introduction" and "Mage Promotion Path," Li Qing only briefly skimmed through them. Magic runes are more about setting up magic arrays and enchantments, and while learning runes is possible, the focus for now remains on learning Level 0 Magic.
The Mage Promotion Path merely discusses the standards for mage hierarchy and the various paths derived from magic.
Demon Swordmasters, Warlocks, Priests, Knights, and dozens of other career paths.
For Li Qing at the moment, there is no significance unless he reaches the level of an Advanced Magic Apprentice and considers career advancement, then he might have time to study these.
He walked and pondered along the way, when a voice suddenly came from beside him.
"Fellow student from the human world, are you heading to the library?"
Li Qing was startled awake and looked back to see the other party in black robes, then relaxed again. Walking along roads shrouded in mist made everything seem eerie.
