"Hahahahahahaha!"
Old Man Shiyū let out a malicious, gloating laugh from the side.
Finally, he said, "Mushi-Hime, you work hard on your own. This old man won't accompany you."
This old man has become an old man.
With that, he ambled away, leaning on his cane.
Miki glanced at Old Man Shiyū.
When Shinobi reach a certain age, their physical condition rapidly declines, mostly because the frequent use of Chakra in their youth overdraws their body's lifespan.
Fifty or sixty years old is considered a long life.
The average lifespan during the Sengoku period was around thirty years old.
Going to the battlefield at five or six years old seemed very normal.
Among them, due to the Oil Girl Clan's secret insect nest Ninjutsu, this physical condition is even more severe.
Even though Old Man Shiyū had been putting on a strong front, Miki knew from yesterday that he was already running out of energy.
As he said himself, he didn't have many years left to live.
He was, as he said, a short-lived fellow who started building his nest in infancy, and it was unknown what important organs he had injured.
Because of this, most of the Aburame Clan do not specialize in Taijutsu.
This is because, compared to normal Shinobi, the physical strength of the Aburame Clan is too poor.
After glancing at Old Man Shiyū's retreating back, Miki got up from the ground and looked at Old Man Shihu.
That's why Miki hated the eager, hopeful gazes of her elders; it was truly impossible not to respond.
Therefore, she could only work hard herself.
Although it sounded like she was cultivating for Old Man Shiyū, Miki also had her own pace of progress.
"Did you understand?" Old Man Shihu asked.
"Your arms are longer than mine," Miki said, feeling depressed.
In her current squat, short stature, she was at a great disadvantage in all aspects.
"What else?"
"Your wrist strength is stronger than mine."
"Then what are your own advantages?" Shihu asked.
"Agility?" Miki replied.
"That's barely it," Old Man Shihu said. "What else?"
"I think I should use a weapon, like a sword," Miki said. "Grandpa Shihu shouldn't mind, right?"
"A weapon, you say?" Shihu said. "Swordsmanship is also a type of Taijutsu."
"Very good."
As he spoke, the microscopic battle between the insects ended.
The poisonous insects that Shihu had used to invade Miki's body during the attack were all completely annihilated.
On the surface, the purple on Miki's hand merely wriggled for a moment, then calmed down.
The same was true for Shihu's hand; while attacking, he was also attacked by Miki.
Old Man Shihu glanced at his hand and said, "As long as there is physical contact, you will be attacked. Most Shinobi would be killed quickly."
"What about unusual Shinobi?"
"You won't be able to touch him," Old Man Shihu said, speaking from his own experience.
"Therefore, my Taijutsu is about finding a way to touch the opponent."
"As long as I plant the poisonous insects, it's my victory."
Such practical Taijutsu.
"Attaching Parasitic Minute Bugs to metal, while possible, is very difficult."
"But for you, Mushi-Hime, it shouldn't be a problem."
"And your wrist strength, Mushi-Hime, is too small, which is due to being part of our Aburame Clan, and being a girl, your wrist strength is even more inferior. Avoiding head-on clashes is your Taijutsu."
"Using the advantage of a weapon is a good method."
"However, the weight of a sword would be a considerable burden for you."
"Are there no lighter swords?" Miki asked.
Practical is good; practical means simple and easy to learn.
After a moment of contemplation, Old Man Shihu looked at Old Man Shihō.
Brother, what should I do if I don't know swordsmanship?
Old Man Shihō said, "There are lighter swords, yes."
With that, he released a swarm of Insects to send a message.
"When I was young, Grandpa, I collected quite a few similar items. If there's anything else you want, just tell Grandpa."
"Thank you, Grandpa," Miki said with a sweet smile.
"Mushi-Hime," Old Man Shihu began, drawing Miki's attention back, and said, "Because Parasitic Minute Bugs are too tiny, their wings have degenerated, and they cannot move at high speed by flying. They can only spread through close physical contact."
"So, do you know how to expand the attack range of the Parasitic Minute Bugs?"
Miki thought for a moment and said, "Wind!"
Airborne viral transmission is common knowledge.
If they can only float and have difficulty moving on their own, then they must use the power of the wind.
"Exactly," Shihu said. "There's something called Shinobi Taijutsu, which is Taijutsu activated by the power of Earth Release. Its power is greater than ordinary Ninjutsu."
"Because of my weakness in wrist strength, I could only find a way to increase speed, and this Shinobi Taijutsu was born for that purpose."
"But to master this Shinobi Taijutsu, the first thing you need to master is the nature transformation of wind."
"Mushi-Hime, what do you think wind is like?"
"What is wind like?" The Mushi-Hime thought for a moment and said, "Temperature change."
"Huh?" Old Man Shihu had a head full of question marks and looked at Old Man Shihō.
Brother, I completely don't understand what she's saying.
Isn't wind sharp?
"Temperature change?" Old Man Shihō asked. "Why do you say that?"
"The change in wind is due to solar thermal radiation. Sunlight shines on the surface, the surface air heats up and rises, and the phenomenon of low-temperature cold air flowing horizontally into the empty space is wind."
"Mushi-Hime, what you're talking about is a natural phenomenon. Chakra can simulate the form of wind according to your imagination," Old Man Shihō said.
Old Man Shihu reached out, and without forming hand seals, a gust of wind rose from his hand, and along with the wind, purple smoke danced.
"Wind is a very rare Chakra nature. Generally, during testing, if the test paper is cut in half, it's a Wind Release nature. Because of this, most people believe that wind is a nature transformation of tearing and cutting."
"And people often understand the direction of the wind as a change in the form of the wind, which cannot be said to be wrong."
"However, within the change in the form of wind, there is also a hidden nature transformation, which is wind speed."
As he spoke, Old Man Shihu took a deep breath, followed by a large cloud of purple mist violently spewing from his mouth.
"Speed is power!"
"This is Ninjutsu without hand seals."
Miki narrowed her eyes.
Isn't this just momentum, or rather, a vector?
That is, the physical quantity of an object's mass and velocity, referring to the effect of a moving object.
Like Asuma's Wind Blade, the nature transformation of sharpness and thinness is essentially the application of vectors.
And the wind speed Old Man Shihu spoke of refers to mechanical motion.
The mechanical motion of an object does not occur in isolation; it interacts with surrounding objects, manifesting as a process of mechanical motion transfer between the moving object and its surroundings.
Momentum is precisely the physical quantity that measures mechanical motion from the perspective of mechanical motion transfer.
The result of the transfer is that the total momentum remains unchanged.
To put it more simply and vividly, fanning oneself with a fan is a process of mechanical motion transfer.
The more force you use, the stronger the wind you create.
Here, Chakra replaces the fan and interacts with the surrounding air, causing strong winds.
I understand!
Miki suddenly clasped her hands together, inhaled, and exhaled.
No purple mist spewed out.
A mouthful of nanoscopic poisonous insects mixed with saliva was swallowed back by Miki.
Hand: No, you don't know yet.
Miki awkwardly lowered her hands.
"Do you understand?" Shihu asked.
"I was just trying," Miki said.
"The key is to apply pressure and area to cause more wind oscillation," Shihu said, sharing his experience. "You need to practice more."
"Mhm," Miki nodded obediently.
She reached up and adjusted her mask; this mask needed to be modified, mainly because it covered her mouth and affected her Ninjutsu performance.
"Once you can do this, you can cultivate my secret Shinobi Taijutsu, and since you, Mushi-Hime, have Wind Release Chakra, that saves a lot of effort."
