Transmigrated into One Piece world with a Gift Pack - Chapter 202: Battle of Superpowers

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!”

These days, could one really time-travel just by dreaming? And to become a silly princess at that. Well, marrying a domineering man wasn't too bad. His taking a concubine wasn't the end of the world either. But why was she forbidden from liking anything except him? That was just too domineering! She had to escape! Ah, but upon escaping, she realized he was a half-demon who didn't understand love... and, moreover, a half-demon who had a three-lives connection with her...

While creating her character, the game’s system randomly generated a “unique” name for her.

Swordmaster Karyl MacGovern.

He returned to the past, wanting to rewrite the future he was unable to change with his sword alone. And this time, he would acquire the power that once eluded him—magic.

This time, he would master both sword and magic, and stand on the peak.
