Where does the story begin?

Shi Chuan's maternal grandfather is Wang Yuzhang, a well-known pharmaceutical engineering researcher in China, and his maternal grandmother is Yu Yi, vice president of the National Writers Association, a famous scholar and writer. is such a young and promising fairy couple that everyone envies, but later, they became the object of everyone's sighs and sighs.

The accident occurred 40 years ago, when Shichuan's mother Wang Ruohong was only nine years old, and Yu Yi collapsed in the summer of that year.

It was a morning, and the family was doing their morning business. Wang Yuzhang was reading the newspaper in the living room, Wang Ruohong had just gotten up early to brush her teeth in the bathroom, and Yu Yi was preparing breakfast in the kitchen. It was such an ordinary morning, but the silence was broken by a "clang".

The voice came from the kitchen, Wang Yuzhang put down the newspaper and shouted Yu Yi's name twice to the kitchen, but no one responded, so he hurriedly walked to the kitchen, Yu Yi was already lying on the floor of the kitchen, the vegetable washing basin also fell to the ground, the water was spilled on the ground, and the green vegetable leaves fell on the corner of Yu Yi's clothes.

Wang Ruohong later recalled to Shi Chuan and said: "After that day, our home was like a change, that day after my father called the emergency number, he hugged his mother on the sofa and waited, I have never seen such a father, that was the first time I saw him crying, his hands were shaking." ”

"Mr. Qian Zhongshu once said to Mr. Yang Jiang, 'From now on, we will only die, and never leave', I think this sentence can also be used on my father, since my mother fell ill."

After Yu Yi was sent to the hospital, Wang Yuzhang hugged Wang Ruohong and waited outside the operating room. An hour, two hours passed...... It wasn't until the fourth hour that the lights in the operating room went out. Wang Yuzhang got up and greeted the doctor. In the office, the doctor handed the diagnosis to Wang Yuzhang and said with some regret: "Mrs. Wang has a very rare disease, and her own immunity will gradually collapse, you should understand what the consequences will be after the loss of immunity." Moreover, there is no effective treatment and specific drug for this disease for the time being, and we preliminarily judge that this disease is likely to be inherited with the X chromosome...... I recommend transferring Mrs. Wang to the sterile room first......"

In this otherwise happy family, this is undoubtedly a disaster.

Even though he knew that this disease was basically incurable, Wang Yuzhang still did not give up. Since then, Wang Yuzhang and his team have been working day and night on drugs to combat these diseases. His daily journey became two points and one line, from the laboratory to the hospital, and from the hospital to the laboratory. After a full body disinfection every day, they can enter the sterile room, and the couple can't even do the simplest kiss.

Yu Yi later mentioned in his memoirs: "During that time, Yuzhang would come to see me on time every night, but he only rested in the room for three or four hours before leaving to go to the laboratory. I advised him to give up or not, but he wouldn't allow it. But I don't want the end to be that I am gone, he also falls, and we still have Ruohong, he has to live well, otherwise our daughter will be alone in the world, how lonely it will be. ”

Wang Yuzhang has no other thoughts, he just wants to keep Yu Yi and let her be healthy and happy in the world. Unfortunately, the year after that, Yu Yi left. She walked in pain. The viral influenza that others could cure by taking a few doses of medicine or taking a few drips completely crushed her.

There are very few drugs on the market today to fight off viruses, and for diseases such as the viral flu, we usually use drugs to relieve complications and then destroy the virus through our own immune system.

On the day Yu Yi left, Wang Yuzhang seemed to be ten years old, and he was only in his thirties, and he looked nearly fifty years old. He can always remember that when someone asked Yu Yi if they arranged a marriage for their parents, Yu Yi smiled and said: "We are free to fall in love first, and then our parents arrange it." ”

After Yu Yi's death, Wang Yuzhang did not stop researching, at this time he was not only obsessed with the obsession in his heart, but also the uncertainty that this disease was inherited with the X chromosome, if their Ruohong ...... He didn't dare to think about it anymore.

Fortunately, Wang Ruohong grew up smoothly. Wang Yuzhang took her for physical examination twice a year, and the results of the physical examination were normal. The drug he developed was not clinically tested because of the small number of cases. Just when he thought that the medicine he had developed would never be put into use, and that his family would never befall such a catastrophe again, his grandson fell.
