Mushoku Tensei - Volume 18 Chapter 4 — Ariels Choice

An alien race invaded the Earth on June 6, 2128. At the midst of this war, many nations allied with the alien threat and the war nearly wiped out the rebelling humans of the planet. At the edge of mankind's survival, the United Nations Army launched its forces to eliminate the immediate stellar threats that loomed over Earth.

General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

So begins a new game in the battle for humanity's survival.

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.

Every novel has a slag character, the one who decides to abandon the protagonist at his lowest, most helpless point, either because he can’t stand the poor guy’s circumstances or for other reasons. But after the protagonist wins his way in life again, they’re the ones who beg with broken sobs to be taken back.

Still, water once spilled can’t be recovered again.

Yet the unlucky Shen Jiayan has been bound to a Water Recovery* System to do just that.

*water recovery – comes from an idiom that means “spilled water can’t be recovered” (English equivalent: there’s no use crying over spilt milk).
