In a contaminated world on the brink of collapsing under countless dungeons, a harsh place where if you were unable to summon a creature, it meant you could die at any moment. Alas, the chance of summoning was very low for anyone—except nobles.
 
Four people were reincarnated. All of them were reincarnated into the bodies of geniuses, who was favored by Gods, except one.

A fourth-year university student was reincarnated as a nameless slave and had contracted an illness—mana circulation disorder—that would prevent him from living past 30.

His only chance was to summon something decent. Luckily for him, a second chance appeared… A challenge from the gods… By getting through it, he finally gained what he wanted.

A sword demon....one of demon kings.
[Do you want to evolve your summon?]
[Your summon has two paths to evolve]
–[Hellfire Demon]
–[Wind Demon]

However, that was just the beginning of a Godslayer’s fate when he figured out the reincarnators were his enemies.

[Author’s Note]

*Is the MC a slave? Yes, he is, but it’s just a leftover label from his old identity in this world. The moment Alaric, a fourth-year university student, reincarnated into that slave body, I don’t think he should even be considered a slave anymore. Moreover, he gets rid of his inferior identity once he clears the final challenge of the Nameless God in Chapter 18.

*Is the MC OP? Not exactly, since his early power isn’t really a cheat. The real cheat everyone expects only shows up after Chapter 19.

*The world is split into two distinct classes:


+Summoners(40%): possess everything: status, power, money, high lifepans, etc->live in center of the world in safe.


+Non-summoners(60%): They could not survive till 30 years by mana circulation disorder->live in border of the world of where is being rampaged by dungeons.


Mana color core:(Green/Blue/Purple/Red/Black) base on summon's evolution stage. 


Potential:Dormant /Awakened /Ascendant /Transcendent.


Evolution stage: 1->5 each stage will have 2 class to evolve.


Mana core count: Each 5 core will evolve one stage( find core by clear dungeon)


*Monster/demons/angels:Mana color core:(Green/Blue/Purple/Red/Black)


*Gacha: Sure, he never recevie what he want...But, My MC will use it properly.


+Normal mission: 5-50 points(related to physical training, muscle torture+duel...etc).


+Life-Dead mission: 250 points( This mission does not involve killing people or monsters directly)


+Killing people or monster directly->depend on color core-mana.


+Killing people or monster indirectly->depend on me :))
