MTL - Civilization: Beyond Two Worlds - ~ This chapter is too long, I can't finish it tonight, I will update it with 10,000 characters tomorrow.

Shi An is the last Abyss Dragon in the world. Since he was bored, he decided to go into a deep sleep while hugging his treasures. After fifty thousand years of satisfying slumber, Shi An opened his eyes only to discover that he had become a weak human with short hands and legs.

He glanced down at his mysteriously downsized body and then lifted his head to look around his empty cave. “……” Where is my powerful and majestic body? My big tail? Most importantly, where are my treasures?!

After thousands of years of hard work, sleeping just once has sent me to square one.

In the year 2202, the conflicts between humans and monsters are becoming more and more intense. Although the monsters are strong, the fantastical species that used to rule the continent have all but disappeared.

Shi An, the Shi family’s youngest son, is Mage Academy’s infamous mage who has no magic power. Each student’s magic power is measured at the beginning of the school year. Shi An looked at the three destroyed magic detection equipment and innocently asked, “Eh? Are these equipment’s quality not very good?”

During actual combat training, low-ranked monsters fled before Shi An could get close. Shi An looked at their fleeing figures and innocently exclaimed, “Yay, lucky!”

Everyone else was speechless. “……?” I believe I am dreaming.

Mu Heng——human species’ strongest mage——is the only remaining human who bears the noble dragon slayer bloodline.

He coldly and arrogantly said, “Dragons? Extinction is their best outcome.”

A long time later, Mu Heng turned his head back to look at the dragon cub reclining on the piles of treasure. Mu Heng withdrew his gaze and leisurely asked, “Are there any other jobs? I want a well-paid one.”

Extinction is out of the question now. As a matter of fact, I can only earn more money so that I won’t get kicked out of bed at night.

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!”

- Description from Novelupdates

I became a side-character who died in anguish because of her good-for-nothing husband.

If I can’t avoid getting married, why don’t I change who I marry instead?

“Excellent, marriage sounds good.”

“Wise choice. Then let’s have a wedding ceremony that isn’t too ceremonious. Following that, I’ll need you to go down to the Fief and behave like the lady of the house until I call for you. Naturally, there won’t be any time to spend in leisure whilst dousing yourself in luxuries.”

“I’m not marrying you, but your father instead.”

“……Pardon?”

“I’m not going to marry you. Do you have a problem with that?”
