MTL - First Day In Game, I Got Ten Billion From Infinite Number Of Check-ins - Chapter 527 talk about

Mutations occurred around the whole world and soon, a demonic apocalypse befell.

In order to defend against demonic beings, humans swiftly entered a globalized digital age. Everyone would be able to choose between a fighting or a supporting job through awakening once they reached the age of 18. These people would get stronger by slaying demonic beings.

Lu Yan had awakened to the weakest job, a Necromancer. However, he had also received a Job Supporting System and was able to reawaken into a hidden job, Lord of the Death.

“Necromancers are so weak that they die in one hit!”

“Man, that dude’s luck is just the worst. He did get a fighting job, but it’s the weakest. What can he do? Summon a few skeletons?”

“Also, aren’t there only like a handful of Necromancers out there? There aren’t a lot of experience or resources for them to inherit. Their future seems bleak.”

“Forget Necromancers! I got the Holy Knight job! Your all-around king is here!”

Not long after that, Lu Yan appeared in a full set of Death Nether Armor while wielding the Death Soul Scythe and leading a 100 thousand-strong death army. With a single swing of his scythe, he split the mythical rank demonic beast in half.

“Necromancers are weak? What does that have to do with me, the Lord of the Death?”

"The boy has no powers," they claimed.

He holds a god-level sign-in system in his hand, punches the goose factory, and steps on the pig factory. Do you think there is no good game?
First feed you two mouthfuls of tainted milk powder, and then send you the legend of the dragon and the Hearthstone gold cartoon for free.
What? Still not satisfied? League of Kings out-of-print skin, give away!
Satisfied? Tch, this is just the beginning…
