This is a world where games have invaded reality.
Every year, students turning 18 awaken to a job change.
One person crossed over and became a Necromancer.
Relying on a luck-based talent that made wishes come true and a legacy from Mother Earth, this person rapidly gained power.
While others gambled on skill mutations, summoning variations, and the chance with endless resources,
he simply needed to shake his talent and use the least resources to obtain everything.
With an undead frenzy, he broke through the blockades of the other nations on Blue Star, making his empire great again.
With the undead scourge, he wiped out the decayed porcine dynasties within realm territories and became the new Realm Master.
In the name of the Dead Spirit Overlord, he waged war on the Battlefield of Ten Thousand Tribes and ascended to the throne of the Demon God.
