In a flash, a year passed.
A child named Saitama was born, delivered in Konoha Hospital.
Waaah~
A baby's cry echoed through Konoha Hospital, heard by everyone.
It was so loud and clear.
"What strong lungs."
Shizune walked out holding a child and said to Satoru.
Indeed, very strong.
A newborn baby, capable of crying so loudly.
Satoru was quite surprised.
He had felt Ayame's vitality before the birth, but he hadn't expected such an unusual phenomenon after the birth.
That's right.
A sound that could be heard throughout the entire hospital was indeed an unusual phenomenon.
Other medical Ninja nearby, hearing the sound, came over to see what was happening.
They were quickly shooed away by Shizune.
"Satoru, this child's vitality is even higher than Naruto's."
Shizune had examined Naruto's body, and she could sense the powerful vitality emanating from Saitama.
As well as the immense Chakra swirling around his Chakra System.
He was born with powerful life force and Chakra.
"It is a bit high, I'm just worried he might not be too bright."
Giving him the name Saitama, Satoru also felt the powerful vitality in his fourth son's body and had high hopes for him.
This thought was fleeting.
But he also worried if his mind might not be too good later on.
After all, his previous children, Tenyu and the Maki dragon-phoenix twins, inherited his sensory abilities.
Keigo inherited his intellectual abilities.
Now, this child, born after his body had evolved to be even more perfect, might only inherit his Physical Training abilities.
Especially the vitality within him.
It truly had a connection with his Physical Training System, which he had already developed and was just waiting for Physical Training Ninja to come and test.
If that Physical Training System had powerful vitality, then the training effect would certainly be much better than for others.
After all, it was Physical Training, not Ninjutsu.
If the body's self-healing could support sufficient training without relying on medicine, it would certainly be advantageous compared to others.
Shizune was a bit speechless upon hearing this: "Is there anyone who talks down about their own child like that?"
Though she said that, Shizune was a bit envious.
She had been so busy these past few years that she still hadn't found a partner.
It was driving her crazy.
She was already thirty-four years old, and for the development of Konoha, she had become an older single woman.
Just like the Mizukage of the Hidden Mist Village across the way.
Sigh!
Who could possibly fall in love with someone as constantly busy as her?
She also wanted to have a baby.
Especially since she knew that Sakura, Ino, Tenten, and other acquaintances from the new generation who had gotten married were now all married and pregnant.
Naruto's child would also be born in seven or eight months, and she was incredibly envious.
"Should I just settle down with Kakashi?" Shizune sometimes thought.
But Kakashi wasn't someone suitable for a relationship.
He wasn't her ideal partner.
And Kakashi wasn't interested in her either.
It was so difficult.
"I'm not talking him down, sigh, Ayame's condition is alright, I guess. Or should I use Ninjutsu to help her recover?"
Satoru took the child, looking at his head, which had no fetal hair, and had a bad premonition.
But he still cared about his wife inside first.
Shizune: "No need, you hold the child first. Let Ayame recover on her own; using Ninjutsu for everything isn't good for the body."
...
Ayame wasn't a Ninja, so Satoru thought about it and decided it was fine to let her experience it.
It would just take a little longer to recover.
"Oh my god, just thinking about how many more children I'll have to deliver in the future makes me sick."
Shizune was beyond words.
Especially now that Sakura and Ino were both pregnant and at home, not working at the hospital, she had to manage all the hospital's affairs, big and small.
She was fed up.
"Why don't you apply for retirement with Kakashi? It's time you found a partner, otherwise, when you're old, you'll just be watching them raise their children."
Satoru also offered advice.
...
"No, Lady Tsunade entrusted this position to me, so I must do it well. Let's wait a bit longer!"
"Suit yourself. Anyway, I only do what I like now, and living a retired life is wonderful."
Satoru chuckled, holding Saitama, and used Ninjutsu to examine his body.
He found that besides his powerful vitality, there was indeed a single-mindedness in his brain, suppressing his mind and preventing the activeness seen in his other brothers.
And this single-mindedness was connected to various parts of his body.
The immense vitality originated from this single-mindedness.
It was just like the Uchiha's Sharingan, secreting special Chakra within the body.
It allowed the use of special powers.
This single-mindedness was just such a thing.
After physical training, his body would generate special Chakra, thereby liberating his body.
He was simply a genius of Physical Training.
Pupil techniques are called pupil power, and this single-mindedness is called life, a limiter?
Satoru performed a Sealing Jutsu, sealing this single-mindedness first.
Because it completely suppressed other things in the brain.
It would likely suppress his intelligence.
Even so, this single-mindedness was still exerting its power.
Just much less than before.
"Let's unseal him after he graduates from Ninja Academy, otherwise, I'm afraid he'll really be single-minded."
Satoru still chose to seal his power, preparing to unseal it only after he formed a complete worldview and values at the Ninja Academy.
Shizune also saw his actions, but she didn't interfere.
Satoru wouldn't do anything to harm the child.
Whatever he did, it must be for the child's good.
"Thank you for helping me deliver; actually, other doctors could have done it too." Satoru thanked her.
Shizune's expression grew even uglier: "If it weren't for you being a hero of the Ninja World..."
She had lost another opportunity to find a boyfriend; it was too difficult.
Satoru watched Ayame emerge from the delivery room and walked over.
However, seeing her sleeping soundly, he didn't disturb her further.
Instead, he held the crying Saitama and wandered around the hospital.
He wanted to show Saitama to the other people in the hospital.
"Sensei Satoru, is this your fourth child? Why is he bald?"
Just then, Sai walked over with Ino.
Seeing Satoru, Sai greeted him. Ino, seeing Saitama in Satoru's arms, asked curiously.
Although she managed the intelligence department, she was also a formidable medical Ninja and had delivered babies, but she had never seen a child without fetal hair.
Sai: "Senior Satoru."
Satoru: "Yes, I can't figure out why he's bald either."
"Ah~ My child won't be bald too, will he? No!" Ino suddenly thought of herself.
If her child was born bald, that image, she really didn't want it to happen.
Sai: "Not necessarily, but he should have yellow hair like you."
"Yellow hair, that's good." Hearing Sai's words, Ino thought about it and agreed; her family's genes were so strong, he would definitely have yellow hair.
