The Simple Life of Killing Demons - Chapter 28Book 12:

Legend says, that there is a great demon, who is the human kind’s public enemy. He is the galaxy federations’ nightmare as he wanted to conquer the whole universe. On the first day, he completely took out the human fleet, plunging them into disorder. On the second day, he declared that he will wipe out the whole federation. On the third day, he declared——that the hero who shot him in their previous battle must marry him, or else, he will destroy everything.

The galaxy federation president and the council members had a long meeting after that. They decided to dispatch a soldier, Wu Xing Yun, and marries him off to the arrogant demon. Wu Xing Yun was once a hero who fought for the nebula, and henceforth, he was tasked—— for the sake human race and the universe’s peace, to eliminate mistresses, settle his matters with the mother-in-law, and fix the man’s crooked ways.

Wu Xing Yun was very perplexed when he asked his commanding officer: “Sir, why did it have to be this way?”

Commanding Officer: “Soldier, bear in mind, that this mission of yours, is for the sake of the universe and mankind’s happiness. You must hold on to your husband, and fight other mistresses! Do you have the confidence to accomplish this task?”

Wu Xing Yun, stood straight, saluted, and instinctively replied: “Sir, yes sir! I will accomplish this task!”

Diane's life crumbles when she discovers her husband Liam's affair with her sister Sophie. Betrayed and heartbroken, she retreats to her friend Joan's beach house, seeking solace. But as plans for revenge take shape, Diane uncovers darker secrets and hidden agendas. Pregnant and determined to protect her future, she embarks on a journey of survival, retribution, and unexpected alliances.

First, this isn’t a story about how to seek survival during Doomsday! It’s rather about how to bring about the end of of times, to bring down the curtain on the world. It’s about how to set off a Zombie frenzy, how to lead the Devil into invasion, and how to guide the descent of Zerg! In this game of doom, I’m the source of everything!

Second, I need to thank those brethren who accompanied me until now. My thanks go to the Lich Monarch, Arthas Menethil (game: World of Warcraft), bringer of endless winter and death; to Alex Mercer (game: Prototype), who created life by consuming viruses; to the Worst Spirit Tokisaki Kurumi (Light Novel: Date a Live), controller of time; to the Magus Ascendant Xerath (Game: League of Legends), imprisoned by runes.

Ladies and Gentlemen, lets bring about a carnival of doom!
