Read Global Job Change: Starting With The Hidden Job, Lord Of The Death

All around the earth, mutations took place, and a demonic apocalypse quickly descended.
Humans quickly transitioned into a globalized digital age in order to guard against evil beings. Once they became 18, everyone would be able to select between a combat or a supporting job through awakening. Slaying demons would make these humans stronger.

Lu Yan has awoken as a Necromancer, the least powerful occupation. He had, however, also been given a Job Supporting System, which allowed him to revive into the concealed position of Lord of the Death.
Necromancers are so frail that they are killed by a single blow.
Man, that guy has the worst luck ever. He did land a fighting job, but it’s the least desirable one. How can he help? Why not call a few skeletons?
Also, aren’t there just a small number of Necromancers in existence? They won’t inherit many resources or years of experience. Their future appears gloomy.
Never mind necromancers! I was hired as a Holy Knight! The all-powerful king of your realm has arrived.
Soon after, Lu Yan emerged, armed with the Death Soul Scythe, a full set of Death Nether Armor, and in charge of a 100,000-man death army. He cut the legendary-level demonic beast in half with a single swing of his scythe.
Are necromancers frail? I am the Lord of Death, what does it have to do with me?
