Shinwa Densetsu no Eiyuu no Isekaitan - Volume 1, Chapter 1 – Encounter Part 1

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!”

Mu Xiaoya lived for twenty-six years before she knew that she had a sudden genetic disease. There was no medicine for it, and there was only death waiting for her.

Before she died, many people came to see her, but she was most impressed by Bai Chuan.

Bai Chuan was her neighbor, an autistic child with scholar’s syndrome. At that time, his face full of scars was desperate: “I – I studied all your medical records, but I have no way to save you.”

Mu Xiaoya was stunned: “You are a doctor?”

Bai Chuan: “I am not… …”

Mu Xiaoya’s disease was a genetic disease. Unless the gene was changed, there was no possibility of cure. However, Bai Chuan was the only person who tried to cure her after she fell ill.

Mu Xiaoya: “Why are you going to cure me?”

Bai Chuan: “I want to marry you.”

Mu Xiaoya laughed: “If you marry me, you will soon become a widower.”

Bai Chuan insisted: “I – I want to marry you.”

Bai Chuan, who has cognitive impairments, can’t express his meaning very well, and can only repeat it over and over again.

Later, Mu Xiaoya still died. When she woke up, she returned to the summer of her college graduation.

Bai Chuan: “I… I want to marry you.”

Mu Xiaoya: “Good.”

The starlight in the eyes of Bai Chuan was the most beautiful scenery that Mu Xiaoya had ever seen in her life.
