THE CULINARY Hunters.
When the First Apocalypse started, it was hunger that killed most people and not dungeon monsters.
Fortunately, with the emergence of Culinary Hunters— those who discovered that plenty of dungeon monsters, plants, vegetables, fruits, etc. were edible and safe for human consumption— the hunger problem in the world was solved.
Hence, they were celebrated all over the world.
And it remained that way even after the Second Apocalypse.
However…
"Bitna-ya, I understand the importance of Culinary Hunters," Wonhee said carefully. Of course, she knew that Bitna wasn't done talking yet. Hence, she added: "We need to increase the Mana of this world in order to drive away the Cracks and the dungeon monsters. That was why the System aimed to share my Mana with the rest of the world."
That was the plan before Lee Seodam destroyed Wonhee's Core.
