History's Strongest Son-In-Law Living With The In-Laws - Chapter 605

A world from another dimension suddenly appeared in the Milky Way galaxy and collided with the earth. A spatial collapse occurred, which allowed the monsters crossing over from the other side to invade various countries, and the earth fell into great calamity.

The military was powerless against the invasion because modern weapons didn't work against monsters from another world. Under the desperate situation, a god-like figure appeared and bestowed blessings upon the humans to awaken their power. From then on, the earth regained its hope, and these extraordinary people were called Realizers.

Tenku Okuihara is a five-year-old boy who dreams of becoming a Realizer to protect the world and his family. But an incident changed his life goal from a hero to a grim reaper.

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

When he got tangled in a fight with a few punks in this different world, he fell off a cliff and miraculously found himself still alive, with two more voices ringing inside his head. They were Sword Master and Saber Master. In the company of them, he continued to find out more about this whole new world. He took the sect entrance examination, entered the sect, met a strange man in black, and even participated in a major competition of the sect to have a chance to win over his peers!
In this whole new world, he was born again and got to explore the fantastic martial world!

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.
