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?”

Like fattening livestock.Shortly before this dark turn of times was a forbidden creature, Kieran who had been born into the lowest levels of a society created by the greed of humans. To him, life had always been hard, but things got worse after the arrival of the Xillthars as he found himself on a trail of shocking discoveries about himself and the world around him.

In the near future, a space channel connecting the other world suddenly appeared on Blue Star, and a large number of other world monsters poured into the homeland where human beings depended for survival.

Human civilization has shrunk sharply and had to hide in the base city to survive.

Only warriors can lead human beings to open up living space and regain lost land.

However, martial arts requires talent, and not everyone can become a martial artist.

People with outstanding martial arts talent can not only advance quickly and break through limits, but also optimize their exercises and benefit future generations, and are admired by all mankind.

By chance, Lu Heng discovered that his martial arts talent could continue to evolve…
