Demon Hunter: School of the Wolf.

In 1179, Ailin traveled to the world of demon hunters.
This year,
The Wolf School was at its peak.
There are more than 20 demon hunters and nearly 50 apprentice demon hunters active in Kaermerhen Castle all year round.
however,
The undercurrent of the school's demise has already been quietly surging.
Under such circumstances, Ailin could not remain immune.
Fortunately, he awakened the Demon Hunting Notes, and he could become stronger by killing monsters.

Ailin:?
Is there something weird mixed in?
……
after many years,
The Demon Hunter Cult's strongholds have spread across the entire continent, surpassing the Wizard Council and becoming the largest neutral organization on the continent.
In the headquarters hall of the Demon Hunter Cult,
Master Ailin, the water ghost killer, monster nemesis, and champion hunter of the mist demon, is explaining his book "Monster Economics" to his apprentices.
"Apprentices, which part of a water ghost is the most valuable?"
"Water ghost brain?"
"wrong!"
"Water ghost tongue?"
"wrong!"
Seeing the respect and confusion in the apprentices' expressions, Ailin's eyes were filled with affection:
"Water ghosts are full of treasures!"
