MTL - This Star is a Bit All-around - Chapter 33 Professor (Second watch for tickets)

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?”
