The Laws of Cultivation: Qi = MC^2 - Chapter 25: The Dao of Maths

Damien Julian is an 18-year-old loser, who has been bullied and mistreated his entire life, at home, he has to deal with his abusive father, and at school, he is constantly been bullied by delinquents, and to make things worse he is always looked down upon by his peers, till one day a mysterious screen appear before him as it said.

[The world has seen the lingering evil in your heart]

[Would you like to be one of the nine demon kings of this world]

[If so what are you willing to sacrifice?]

In the heat of the moment, Damien made a deal with the world, that he would give up everything he owns, or do anything it wants, and in exchange, he shall be reborn as a new Demon King, and what the world required from him as payment was.

[In exchange for power, become a slave of the world, and act as an anti-body for all eternity]

At that moment, Damien agreed, but little did Damien know, that becoming a slave to the world meant he has to be its immune system, what that entail is, that anything that threaten the world must be destroyed even if he has to wipe out humanity, to save it, or assassinate historical figures to bring fort balance or even manipulating events that can potentially end the world, to save the world, this is the story of a necessary evil, not the story of a hero who cares for others.

After his tragic life ended, Aleron expected to reincarnate or transmigrate, but instead, he was transported with his body and summoned as a hero...only to enter a new hell as he had trash stats and couldn't activate his Divine Blessing, prompting the King to extract his boon.He was tortured and onward to being buried alive with his soul ravaged after they removed his Divine Blessing. But all was not lost as Aleron found he had the Ultimate Gacha System at the death's door and initiated his first summon in the Lords of Arcane banner.[Congratulations! You have summoned Darzax the Graveborn, the Sorcerer of Death and Necromancy.]

Transmigrated into a trash body of general's daughter as female lead? Peh! Too mainstream! Transmigrated to be a villainess? Common! What about transmigrating and ending up as cannon fodder? Have read it before!
