As the executor of the Heavenly Dao, Li Suisui descended to the mortal world for a trial. Born under a celestial omen, her birthday was co-opted by her cousin, which left two girls in the Li Family with the same birthday but disparate fortunes.Everyone said Li Suisui was a harbinger of misfortune, a reincarnated curse spirit, who was fated to bring disaster to her family. They wanted to get rid of her as quickly as possible.On the other hand, Li Yanyan was a lucky star, a blessed bag, everyone wanted to latch onto her coattails, trying to rub off as much luck as they could from her.Later on, when hardship befell the Li Family, the elderly matriarch planned to bury Li Suisui alive to change their luck. But Suisui's powerful uncles came from all corners of the world to rescue her.A grandmaster illusionist, an incomparable physician, the world's top God Hunter...it seemed the Li Family had really kicked at an iron plate!Overnight, Li Suisui became the most adored and cherished member of the family.Sneering outsiders said, “Treating a harbinger of disaster as treasure, when she eventually causes all of your deaths, that's when you'll regret it!”Yet as time passed, not only did no harm befall her uncles' families, but they all began to thrive enormously.Her lame uncle regained his mobility, his barren aunt bore twins, the once discordant couple reconciled, the other uncle became the Number One Scholar...

I was a failed experiment

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.

800 years ago, 3000 dimensional gates opened across the entire world. In that moment, it was as if 3000 different colored eyes opened across the world as hordes of monsters swarmed out of these gates like tears.

Some could destroy city walls with one strike; They had bodies the size of a giant and fed on humans

Some latched onto humans, absorbing their bodies’ nutrients and enslaving humans

Some infiltrated the humans’ cities, disguising themselves as normal human beings while feeding upon human blood to sustain themselves.

In a night, the Human race fell to the bottom of the food chain.

The world had turned into a paradise for monsters…
