The Demon Queen's Contract - Chapter 54: I’m a spy

Xue Xi is forced to fall in love at first sight with this dangerous man on their first meeting. With death being the only other option, she makes the first move:

Hope Lauren has read her share of comics. She’s seen supers around her city and even been saved by some on occasion. And she always hoped that she’d be able to join them. With Jack, her grizzled older mentor with secrets that could shake the world, and Pantheon, a new team of heroes, Hope will have to fight against monumental odds to save Oleander City. In a world of action, comedy, tragedy, and adventure, there’s plenty for a new hero to do.*Readers can expect a mostly adventure-themed superhero journey that will include a slice of life, action, and hopefully exciting world-building. It will also contain a slow-burn GL/Yuri plotline, which I'll eventually get to when I feel like it, I guess. This will be a very long story with many arcs*

The head of the London Association of Mages, the most powerful Saint Archmage in the world, Audrey Davis, accidentally transmigrated to another world due to a magic accident. She was an 18-year-old human girl.

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.
