Dad nodded and said, "It should be said that they are both you and your dead compatriots."

"Diet?"

"This cell is the ancestor. We divide it in parallel on it, and then we get many identical cells. But these cells cannot develop normally. We use catalytic technology to obtain many experimental subjects, but they are either deformed or congenital defects. There are more than 300 experimental subjects that died in the whole process. Later, we checked the cause of the failure and determined that it was the tail chain problem of the DNA. However, a doctor suggested using viruses instead of molecular probes for synthesis, but we couldn't find a suitable virus, and later decided to create a virus directly. This process took many years until we acquired German and French technology and completely bought out their virus gene bank. Finally, b13 was born. We merged it with one of the cells, and then the cell suddenly began to divide wildly after being silent for 24 hours. But I don't know why it suddenly became two independent individuals during the division."

"That's the two of us?"

"Yes. These two individuals are you two." The father continued: "After we decided to look for a surrogate mother. A couple of National Security Agency agents who worked at the base decided to accept this task. Then Zhuyue, you were born. When the embryo was inoculated, your mother was already pregnant, and the other fetus in her belly was your sister. In order to avoid the appearance of the two children, we made some minor changes for your sister to make for the different risks."

"My parents are from the Security Bureau?"

Dad laughed. "Can we just take a pregnant woman in the hospital and be a surrogate mother? Of course, we have to find a safe choice for such an important thing."

I asked, "Then why didn't I get put in?"

"What if the fox finds out if the eggs are placed in one basket? For safety period, we decided to separate the two embryos for surrogacy. Even if there is an accident, we can save at least one."

"So you decided that the mother would do the childbirth of another child?"

Dad nodded. "No one is more reliable than us. The embryo can be preserved for a long time before it is formed, but you have already formed primitive embryo cells at that time, and time is very tight. Surrogate mothers are not easy to find, and they must meet many harsh physiological conditions before they can be surrogate. Moreover, we also need reliable people, so we only come by ourselves. But your mother said that since she was born, she must treat you like a normal person, so we decided not to have their own children and raise you as a biological child."

"Then what's going on with my appearance? Why is it so feminine?"

"This actually scared us too. The progenitor cell is actually a female gene cell, and its sex chromosome is xx. But you split into two individuals after being infected by b13. The individual Zhuyue maintained the female gender, but your individual cells were sorted incorrectly when sorting, and the gender chromosome became xy. As a result, you became a boy. But your embryo was split as a female chromosome for the earliest days. Later, only the sex chromosome changed, and the others basically did not change, so you looked like a girl. But don't worry, the chromosome had completely become a male standard when you were born, and it would not affect your future life."

Zhu Yue stared at me for a long time and suddenly smiled and said, "So we are sisters!"

My face turned red to my neck. "Don't talk nonsense. Didn't you listen to my dad? I was already completely male when I was born, but the embryo period was spent in a female state."

My dad also smiled and said, "This is a small technical mistake and there is no harm. I am now more concerned about your thoughts. Do you have any idea about me and your mother?"

I thought for a while and said, "I thank you for your care and raising me. For me, you don't even want children. I am really moved. Although I am not related by blood, we have been living like this for more than 20 years. I don't think it is necessary to mess up the current beautiful life for those nothing."

My dad patted my shoulder excitedly: "Good boy. We will always be your parents."

Zhuyue said with some loss: "But what should my parents do?"

My father said to Zhuyue: "I suggest you don't say anything to them. The price of their help as surrogate parents is to live a normal life without the spy department. It's great that you can keep it like this, and don't complicate things anymore."

I hugged Ziyue's shoulder intimately and said, "You should be happy. I have such a powerful brother for no reason."

Zhu Yue immediately said, "Who said you are bigger than me? We are two people divided by one cell, at most they are the same size."

I immediately pretended to be old-fashioned and said, "From the psychological age, I am still older, so you should be a sister obediently!"

Zi Yue's tone changed: "Sister is just sister. Do you, the brother, give some gifts to meet? Don't you still have angel crystals? Hand it over? Just treat it as a gift to recognize your sister."

"Aren't you already full in the magic pet?"

"Then don't worry. I'm happy whether I'm happy to use it myself or give it to someone, it's my business anyway. Give it a gift!"

Seeing that we had returned to normal, my dad left the office with a smile. Ziyue and I also left the room with a fight.

Although the test results today are quite unexpected, I am still very happy. Although my dad is not a biological father, I have nothing to say about my parents’ care for me. I am not born to be a melancholy person, as long as everyone cares whether he is a natural person. What’s wrong with me being an artificial human being? I have what others have, and I have what others don’t have, and I don’t suffer any losses.
