Senju Hashirama Was a Eunuch All Along
At that time, I couldn't help but go to see you, but when I got there, I saw Uzumaki Mito and you chatting happily. I was unwilling then. After all, my father didn't come, otherwise I would have been the one engaged to you.
Therefore, I made a startling decision. I used the most unique Sealing Jutsu among the Uzumaki Clan's inherited Sealing Jutsu, called ' Life Seal '. I obtained this Sealing Jutsu Sealing Jutsu by chance; it is said to have been created by Asura's wife.
The greatest effect of this Ninjutsu is to induce pregnancy, allowing a person to give birth to a child.
I secretly came to your tent, then took some of the blood from the blanket, and finally used the ' Life Seal '. Ultimately, your cells and the cells of my body finally combined, and together they conceived and grew into our child.
However, your cells and vitality are truly extraordinary. I've done a preliminary calculation, and it will take at least a decade before the child is born.
But so much has happened in the past ten years. You killed my father and wiped out my entire clan. Back then, I hated you, I hated you to death.
I married Senju Hashirama, hoping Senju Hashirama would kill you. But deep down, I still love you.
To prevent Senju Hashirama from touching my body, I used the "Yang-Sealing Technique" to castrate Senju Hashirama when I first joined the Senju Clan. After marrying me, Senju Hashirama couldn't even look me in the eye, because he already knew he was impotent.
So on our wedding day, we moved out of that house. Afterwards, Senju Hashirama's heart was heavy, but he still dared not look me in the eye, and he didn't even dare to enter his own home. Isshin focused all his energy on his training, but that was exactly what I wanted!
However, I soon discovered that long ago, I had used the ' Life Seal ' to seal your cells and mine together, creating an embryo that had begun to develop. In other words, our child was about to be born.
To avoid arousing Senju Hashirama's suspicion, and also for the sake of my revenge plan, I revealed the ' Life Seal ' to Senju Hashirama and took his cells Senju Hashirama their strongest. It was precisely because of this that I made Senju Hashirama believe the child was his when it was born.
Uchiha Kangetsu, my child with you has been born, and I am very happy. I also know that this should be your first child, and also your last. Your life force is strong, and your life level is high, so it is very difficult for you to have a child in your lifetime.
I saw it on the scroll that I obtained the ' Life Seal '. Back then, Asura's life level was very high, and he was unable to reproduce, which is why the ' Life Seal ' Ninjutsu came into being.
Your vitality is so high, which is why your child and I are the only children we have.
But, but, I hate you. When the child was sixteen, I made him marry and have children, and then used Human Body Seal to impregnate my daughter-in-law. But I didn't know that, because of my joy, he awakened the Sharingan."
