One Piece: Don't Worry, I'm a Doctor - Chapter 95: Upgrade?

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!”

As soon as Qin Yao opened her eyes, she was transported into the body of an ancient peasant woman from the end of the world.

There are four stepsons at home waiting to be fed.

A bastard who has nothing but good looks is jumping up and down.

The family lives in a thatched hut with not even a grain of rice in the jar. The whole family is as skinny as refugees.

Forget it, there are still people coming to ask for debts!

Qin Yao was angry from the bottom of her heart and kicked her bastard husband out, “Brother who wants to pay debts, please just beat him to death!”

Four stepsons:! ! !

The world is clean, Qin Yao rolls up her sleeves and makes a fortune.

She is great at hunting, carrying bags, and killing horse thieves.

It is this kind of land, facing the loess and turning its back to the sky. Even the top strong men who have been struggling in the apocalypse wave their hands repeatedly: I can’t stand it! I really can’t stand it!

Qin Yao scratched his head: In ancient times when agricultural taxes were extremely high, how could we stop farming?

At this time, the lazy husband who was sent to die (twisted and crawled) (struggled to stand up) (screamed and roared): Wife! I think I can still save a little more!
