Conquer the game with the strongest characters in web novels

My father, who passed away leaving behind only one key, was a web novel writer specializing in Munchkins.
Ten years later, the virtual reality game ‘The Another World’, based on one of those works, was released.
From basic livelihood to making a fortune, it becomes a place of opportunity and becomes a hit like never before.

Kim Woo-joo, the original author's child, led a difficult life without any benefits.
By chance, he learns that his father's memento, key goods, is being traded at a high price.
Immediately, when he opens the limited edition book in his father's library with the key, he receives a special gift in the game.
The universe accepted the gift, and then the Great Demon King Lucia, a character in his father's web novel, appeared.

Lucia, the Great Demon King, gave the universe abilities and because of its power it couldn't handle it,
Rather, it puts you in an awkward position where you can't even do simple daily quests.
After much deliberation, the universe brought in another work, Killer Zero, to get rid of the demon king, the source of power.
Feeling uneasy, Jason, a limited-edition talent from ‘There Another World’, rushes in and fights back.

Will Woo Joo be able to compete with the best in games with the best in web novels?
