He even picked up a carp that weighed more than two kilograms. Not only did I remember Zhang Yushi and I made the first Red Braised Fish, we did not graduate at that time. When I thought back to it, it was really warm and romantic.

So yesterday was actually the day that Zhang Yushi and I got to know each other. One year ago today, I met Zhang Yushi. And on this day one year later, I received news that Zhang Yushi would be leaving.

I don't like this arrangement.

Old Lin and I focused our conversation on my Advertising company. To be honest, I hadn't really paid much attention to him lately, so I didn't know anything about the situation there. I can tell that Old Lin wants me to develop my career and not always work for Wen Ya.

Lin Xiaole was especially happy to see Zhang Yushi after school. Every time Zhang Yushi brought Arbutin home, she would have another playmate. Not long after escaping, Lin Xiaole's mother would start shouting in the living room, "Lin Zihao, put down that dog, is it dirty? There are so many germs, go wash your hands. "

Lin Xiaole stood where he was and hugged Arbutin, staring at her mother. His expression was too pitiful, and Old Lin said impatiently: "Son, why don't you play with the dog for a while? "Why are you making such a fuss? Xiao Le, go play at the side."

"Daddy is still the best!" Lin Xiaole carried the dog and ran, angering her mother to the point of chasing after him.

Zhang Yushi who was cooking in the kitchen pretended not to hear all of this, Old Lin did not care too much about her wife's ulterior motives, and did not think too much about it. As a father, husband, how could he hope for the family to fall into disarray?

Every time I came to Old Lin's house, he would call me out for a walk after dinner, and they would chat about Zhang Yushi. This time, it was the same as usual. Walking in the small sector, Old Lin handed me the cigarette. I hesitated for a moment before saying, "Uncle Lin, I don't smoke anymore. Shishi doesn't like the smell of smoke."

Old Lin smiled but did not smoke. He put the cigarette away and asked: "How have you and Shishi been lately? Have you considered what to do next? For example … "Marry or something."

"I've thought about it … Uncle Lin, can I ask you something about Zhang Yushi's mother? "

"Ask what you want to know."

"Zhang Yushi's mother really left before she was thirty years old? Zhang Yushi told me that she was suffering from a genetic disease and I was very worried about Zhang Yushi. Yesterday, she suddenly told me all of these, making me feel very at a loss. Also, does Shishi have this kind of inherited disease? "

When Old Lin heard me talk about this topic, he couldn't help but take out a cigarette and light it up. I'm a man, and I understand some of the little tricks a man makes. Especially when a man takes out a cigarette and lights it, that kind of feeling …

"Zhang Yushi's mother left at the age of twenty-nine. As for how her mother left, I have made up countless versions to tell Shishi about them since I was young, but I can't hide some things from her. She grew up and finally found out about these things related to the family's genetic diseases in her mother's diary. It was a blood and heart disease. Zhang Yushi's grandmother also died because of this disease, and the inherited method is for the mother to pass on the child. "

"Does that mean Zhang Yushi has the same disease?"

Old Lin shook his head and said thoughtfully, "I'm not sure. I hope Shishi is safe and sound."

"Can't you check it out?"

"When Shishi was young, I regularly took her to check on her, but this disease can't be found at all. There's too little information about this disease, have you ever heard of 'Panda Blood'?"

I shook my head. Is it the blood of a giant panda? Obviously not.

"Panda blood is a common term for Rh negative blood group, it is one of the Rh blood group systems. According to the theory of cultural archaeology and physiological evolution, RH negative blood may be the blood type of human in ancient times. The distribution of Rh negative blood varies greatly according to race, with a higher proportion of white people, about 15%. "The Han Chinese account for a very small percentage of the population, only three in a thousand. Three out of a thousand isn't that rare, so we must find them for sure, but Shishi and the rest's blood is one of the three in a thousand, so the difference is huge. Shishi's mother and I already had a blood mutation before we got married, so I married her without any hesitation. I hope a miracle will happen."

"Results …" I really shouldn't have said that.

Old Lin took a long drag on his cigarette and said, "Xiaofan, do you know? "The key to this disease lies in the blood. Actually, Shishi's mother didn't have to die that early in the past because there was a way that could be cured in theory."

"Why didn't you cure it? Was there a difference between theory and reality? The treatment has failed? "

Old Lin shook his head and said: "Shishi's mother gave up herself. I, Xiaofan, will say the following words, I hope you don't find me despicable, Shishi shouldn't be living in this world, her birth is a kind of …" Then, I heard a shocking secret.

Originally, the main cause of Zhang Yushi's family's inherited disease was their blood, but their blood was too precious, and couldn't be found. After Zhang Yushi's mother found out about the blood disease, she decided to use a theoretically feasible method of treatment to give birth to a child, because the blood disease would only occur after the age of twenty. The blood of the newborn child was healthy, and they could use the child's blood to exchange blood.

At that time, Old Lin had also agreed to give birth to a child to save his wife. If he were to replace the fresh blood with fresh one, he would be able to continue living for more than twenty years.

Zhang Yushi was born a year later, when she was still a baby. She told him that she really liked her from the bottom of her heart. Seeing that she was her daughter, she felt less guilty, hoping that she would grow up quickly and then draw blood for her mother. Zhang Yushi's blood was exactly the same as her mother's. In theory, the first step was already successful, what was left was to quickly raise her eldest daughter and extract her blood.

When Zhang Yushi was one year old, he was brought to the hospital for the first time to draw blood. At that time, she was only one year old, and didn't understand anything. She adorably sat on the bed and watched the doctor in a white coat pressing the needle on it, completely unaware of her obstinacy and mistreatment.

Old Lin could only hope that the plan to replace blood would work, so he urged the doctor to hurry up. When the small needle pierced Zhang Yushi's skin, she opened her mouth and cried out loud, struggling and not being able to move at all.

Zhang Yushi's mother could not stand watching this any longer. Old Lin told me that in the few dozen seconds he had drawn the blood, he felt as if he had fallen into hell. He couldn't bear to watch any longer, so he turned around and clenched his fists … Zhang Yushi's crying was a memory that she would never be able to forget.

The blood sampling plan was very successful. When Zhang Yushi's blood was injected into her mother's body, the proportion of blood cells detected had decreased, but at that time, Zhang Yushi was only one year old. How much blood did a one year old child have? Enough for an adult? It was obviously impossible. This method could only be of no use.

One morning in the early autumn, the doctor in charge of treating Zhang Yushi's mother called Old Lin into the ward and closed the door. She said a few words to Old Lin and her wife: Your wife's blood is already in a very dangerous state, it will be difficult for her to survive on the child's blood. Your child is already three years old.

Old Lin asked the doctor, "What is a desperate attempt?"

The doctor told Old Lin to give up his daughter's life, draw out all of her blood and put it into her mother's body. Although a three-year-old's blood was not enough for an adult, it should be able to sustain life, and then rely on the hematopoietic stem cells to continue making the blood. However, the doctor didn't dare to guarantee that he could save her mother.

When the doctor finished speaking of his crazy thoughts, Zhang Yushi's mother said that she had given up. She absolutely could not use her daughter's life in exchange for her own.

Before Zhang Yushi's mother passed away, they had prayed for Old Lin to raise Zhang Yushi well. They had already owed Zhang Yushi too much, no child would be born with such an arrangement.

Finally, Zhang Yushi's mother left. When she was packing up her mother's things, Old Lin found a diary that was filled to the brim with notes about Zhang Yushi: "I have learnt to sit up today, I can walk a few steps today with her help. Zhang Yushi has a cold and has taken her blood again … …" These trivial matters recorded Zhang Yushi's growth.

On the last page of the diary, there was a long letter. It was a letter a mother left for her daughter, and after Old Lin saw the letter, he had secretly ripped it off. He had already shown the diary to Zhang Yushi, but the letter was a secret, and it was always kept in a concealed location. Today, Old Lin made an exception and showed it to me.

The yellowed paper was filled with delicate notes. As tears dripped onto the notes, he wrote a tearful letter:

Shishi: When you see this letter, mom must be looking at you in heaven. You must be old by now, and you won't fall down on the ground just because you're walking. You were like this when you were a kid, walking slowly and eating slowly, full of curiosity about something new. Mom can't hold your hand and touch everything in the world, Mom can't leave, Mom is going to go to a place very, very far away, where I can still see you, but I can't touch you, can't hug you.

Mom would love to take you to kindergarten, watch you play with other kids, buy you beautiful flowery dresses in the summer, dress you up beautifully, and make you warm little cotton-padded jacket in the winter to keep your little hands from freezing, these can only be a thought, after Mom leaves, Daddy will take care of you even more.

Looking at your lotus root like hands growing bit by bit, babbling and calling out "Mom, Dad", Mom's heart broke at that moment, and you even came over and used your little hands to wipe Mom's face. Mom really wished she could accompany you for a little longer, but there wasn't much time left …

Shishi, Mom's biggest regret in life is not being able to watch you grow up and even left you with a body that's not healthy enough, and Mom's biggest mistake in life was to make you draw Mom's blood. Every time you cry, you cry until you cry. Why was Mom so selfish? When her mother decided to give up the treatment, she realized that she had underestimated everything. Shishi, can you forgive your mother's selfishness? Mom has let you down. I can't give you a complete life, and I have to take it from you.

Spring leaves and autumn comes, in the blink of an eye you are already 3 years old, every day with you, mother is happy, happy, the thought of about to be separated from you, mother's tears endlessly flowed out, you are still so young, mother will not be with you how lonely you will be. Would you be envious of other kids who have one more mother than you? Will your childhood still be happy?

Sorry, Shishi, Mom is missing your upbringing. Mom really wanted to grow up with you, even if it was 5 years, at least by then my heart had already gone to primary school. But God didn't leave us for a year. He had to take Mom away when Shishi was four years old. Mom lost your grandma at the age of three. Shishi will lose her mom at the age of four, so Shishi must be stronger than everyone else. You must be healthy and happy to grow up, mother will protect you in heaven, mother will add decades of life to your body, may you live for a hundred years.

It's not so good. If Mom was healthy, she could take Shishi out to play like before, take Shishi to be a BIBI, and take Shishi to visit Dad's company. I don't know, after mother left, you can't find mother, how to do? How do you feel when your teacher asks you to sing "Mother is the only good thing in the world"; when your teacher asks you to write "Mother is the best thing in the world"; when your teacher asks you to write "Mother is the best thing in the world"; when someone asks you about your mother, how do you answer?

If there is a next life, let your mother repay everything you have done for your mother in this life, your mother loves you but cannot accompany you, your mother hopes that you will definitely be a happy child, in the future, find someone who loves you, blissfully happy for the rest of your life, your mother will protect your safety and health in heaven.

Love your mother forever.

After reading this letter, I was sure that I was crying in front of Old Lin. Old Lin told me that after all these years, he had been looking for the Variant Panda Blood, and there were about a thousand people who had the Panda Blood. Every time he found a Panda Blood, Old Lin would impatiently request for a test to see if the blood was the same as Zhang Yushi's. He never found this person, but he never gave up and continued to search. Not only at home, but overseas too, Old Lin had spent a lot of money to find this blood. Old Lin told him that this was also the reason why he had to constantly expand his business. How could he treat his daughter if he didn't have enough money?

Now that Zhang Yushi already knows about the genetic disease, Old Lin told me to bring these two pages to Zhang Yushi. This is a letter her mother sent her, a letter that was 21 years late. Would he be able to find that kind of mutated panda blood? Also! Could you use Zhang Yushi's blood to nurture the new blood out? Isn't there a technology called cloning? Can you clone blood? I have to check it out.
