Since that day, Hakushi never mentioned casually treating Ayane to a meal anymore.
Because that might mean he'd go bankrupt.
For her appetite, I, Chiba Hakushi, would call her the strongest!
Time slowly passed, and days went by.
Due to the ramen incident, the three of them grew closer in their relationship.
After all, they had the profound friendship of having eaten ramen together.
Hakushi's performance in class remained unremarkable, compared to his two genius female classmates, his grades could only be described as ordinary.
A month went by in a blink.
During this month, Hakushi and Ayane's relationship became much closer, but his relationship with Ruri became even better.
Of course, it was purely a friendship.
After all, Ruri was the only one who knew about his hidden true strength. If he showed his true strength, he could definitely be in the top three in the class.
The reason for increasing closeness with Ruri was that after school in the afternoons, Ruri often sought Hakushi for physical skill training.
And in this physical skill training, both Hakushi and Ruri were immensely satisfied with each other's superb skills.
Although Hakushi didn't have much combat experience, he could learn from Ruri, who had a private tutor in the Uchiha Clan teaching her combat techniques. These techniques were also passed on to Hakushi, allowing him to gradually reach her level in combat and validate each other's growth.
Hakushi's growth exceeded Ruri's expectations.
As she interacted more with Hakushi, she found herself gradually being unable to suppress him. It was estimated that soon, she would be completely overpowered by him.
This was something that Uchiha Ruri, as a genius, found hard to accept.
Every week she had elite Jonin from the clan teaching her combat techniques, yet within just a month or two, the guy she always suppressed was turning the tables, leaving a stain on her Uchiha genius reputation.
Thus, she must regain control and put him back underneath her.
To reclaim the Uchiha Race's renown.
"Why has your strength grown so quickly?"
Ruri voiced her inner confusion.
In her view, Hakushi must be hiding some secret to quickly becoming stronger.
Otherwise, it was impossible for a civilian to maintain the same rate of strength growth as her, without any guidance.
Otherwise, the problem must lie in Hakushi himself.
"Hmm?" Hakushi was slightly taken aback and said, "I'm just training step by step."
"Impossible, if that were the case, you couldn't have grown so quickly. You must be hiding something."
"I'm really not hiding anything."
"Really?"
Ruri still looked at Hakushi with a suspicious gaze.
"Yeah, I've always been training according to my method."
Hakushi said earnestly.
He really wasn't hiding anything.
Ruri taught him so many combat techniques, and he was very grateful. If it weren't for Ruri, his strength wouldn't have increased so quickly.
"Your method?"
Ruri found a blind spot.
"Yes, I have a scientifically tailored exercise plan for myself, which can effectively enhance my dynamic vision and nerve response abilities."
Hakushi answered honestly.
"Then let me see your so-called scientific plan."
Upon hearing Ruri's request, Hakushi didn't refuse. If it were someone else, he would need to think about it first, but his quick growth was also due to Ruri's help.
Treating people with sincerity, Hakushi naturally couldn't be stingy.
He took a small notebook out of his Ninja Tool Bag and placed it in Ruri's hands.
His scientifically crafted physical exercise plan was recorded in this notebook.
Ruri opened it and looked at it carefully, her expression growing more peculiar as she read on.
Because it was too ordinary.
The training methods Hakushi wrote down weren't really secrets, many of them were things Ruri knew, except for some rather strange training methods that Ruri wasn't familiar with.
According to the methods written here, could she really become stronger?
Ruri had a big question mark in her mind.
Hakushi knew that Ruri was doubtful because his scientifically-tailored physical training plan wasn't really difficult overall, except for some parts that were difficult to perform, but most of it was straightforward and understandable.
However, Hakushi knew that this was the most scientifically sound training plan that fits the human body.
But compared to this scientific training, Hakushi thought that the Chakra of this world was truly amazing.
Why can Chakra turn into fire, lightning, storms... these are all the fascinating aspects.
Compared to the wonders of Chakra, Hakushi felt that his scientific training plan was just child's play.
This scientific training method was merely to enhance Hakushi's dynamic vision, nerve reflex abilities, maintain body flexibility, and a certain level of resistance to impact.
Compared to Chakra, such a magical energy, it was indeed mundane.
Ruri had her doubts, which Hakushi understood.
"If I train according to this scientific training plan, will I also become stronger as quickly as you?"
What Ruri cared about was this point.
"Well, it's hard to say, because it's adjusted according to my physical growth, with a new plan every month."
Hakushi explained.
Ruri nodded in understanding.
What suits Hakushi might not suit her.
So, Ruri gave it a serious look and said, "Make a training plan suitable for me."
She wanted to see if Hakushi's method was really effective.
"It's possible… however..."
Hakushi awkwardly scratched his head, feeling a bit embarrassed to speak.
"What? You don't want to?"
Ruri's eyes, black and white, immediately turned dangerous, shining with a fierce light.
"Ah, that's not the reason, but to tailor a scientific training plan for someone else, you need to start from his physical condition... uh, to put it simply, you must start from reality and be practical... only by understanding the other person's physical state can you tailor..."
Hakushi's expression suddenly turned unnatural, his gaze wandering over Ruri's petite form before nervously looking away.
Really, he's not into girls or underage stuff.
"....."
Ruri's cold face suddenly blushed.
She understood Hakushi's words very well.
Ruri took a deep breath and looked at Hakushi coldly, as if she was looking at a dead man.
"Come over and touch."
"Huh? Okay! Huh? No, what did you just say? Touch... what?"
Hakushi was dumbfounded.
He thought Ruri would back off, but he didn't expect her to say that.
"Just come here and touch me! If you dare to randomly touch somewhere else, you'll be dead meat!"
She fiercely threatened Hakushi.
Hakushi felt he might be killed if he went over.
...
Eventually, Hakushi crafted a tailored scientific training plan for Ruri.
Before Ruri left, she said if this training plan didn't work, she would make sure he'd experience true physiological death!
