I lost my Copy System and awakened a Plundering System - Chapter 243: Battling with the Enemies (4)

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!”

Author : Yi Shi Si Zhou 一十四洲“Until the day humanity falls.”In the year 2020, Earth’s magnetic poles disappeared and humankind was nearly wiped out by cosmic radiation. Within the span of a hundred years, living creatures began to mutate and devour each other while the remaining humans, numbering in the tens of thousands, struggled bitterly in their man-made bases.In the Abyss, home to the mutated xenogenics, there lived a sentient little mushroom. Because it had been nourished by the blood and flesh of the deceased human An Ze, not only did it take on a similar-looking human form, but a similar name as well: An Zhe.An Zhe is determined to go to the human base to search for his spore, which had been harvested by humans. Once there, however, he faces the omnipresent risk of discovery and certain death as he tries to keep his non-human nature hidden from the Judges, whose responsibility is to inspect for and eliminate xenogenics like himself. And of all the Judges, Colonel Lu Feng is the most perceptive and merciless—as soon as he determines that someone is a xenogenic, he will execute that person on the spot.But An Zhe’s mutation goes undetected by Lu Feng’s eyes, and so a tale of humans and xenogenics unfolds…

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
