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!”

Song Yun had given the best years of her life to Gu Yuanzhou, helping him reach the pinnacle of his career, bearing him sons and daughters.

On the night that she died in the raging fire, he was entwined in a passionate moment with his shining moonlight.

Only in death did she realize that she was nothing more than a tool to him.

Upon reincarnation, she vowed to take back all she had given him…

The story of an emergency room doctor dying from overwork and crossing into another world.

…

The sails of the great voyage have been unfurled.

The steam engine has yet to roar to life.

The glory of the Radiant Lord illuminates the continent, while across the sea, the churches of the gods and mages support the monarchy.

Dwarves freely roam the cities of the kingdom, and the legends of werewolves, vampires, elves, and dragons never fade.

In such an era, Wu Zhou, an emergency department doctor who died from working overtime, transmigrates into the body of Garrett, a young city guard.

Teammate: Oh no! The Captain is seriously injured, his intestines are spilling out!

Garrett: Help me up; I can still stitch!

Teammate: …What?

Garrett: …Apply a healing spell to where I stitched, let it grow… no, first apply it to the stitched layer, then the muscle layer, and so on.

Teammate: …What?

Garrett: Uh-oh, the healing spell is too fast, the stitches grew inside the wound!!!

When modern medicine meets magic and divine arts, what brilliant sparks will it ignite in this New world?

Garrett: Learning magic, mastering divine arts, expanding territories, and clashing with the church… whether you believe it or not, I just wanted to open a hospital.
