The next few days passed with Uchiha Tenxiu's cultivation.
Through diligent study of the cultivation method, combined with his natural talent and abundant resources, Uchiha Tenxiu's cultivation progressed by leaps and bounds.
He quickly entered the fourth minor stage of the first chapter, Refining Essence, and was about to begin the Qi Cultivation chapter.
However, during this cultivation process, Uchiha Tenxiu also discovered some issues.
The cultivation method was indeed a secret technique that increased one's own abilities by a percentage.
Perhaps in other worlds, the frail human body's cultivation only resulted in a twofold increase in physical attributes, but when applied to a Ninja World body with 130 trillion cells, where spiritual and physical strength are at least three times that of ordinary people, the actual potential difference is 3 x 3, or nine times.
For example, even though Uchiha Tenxiu had not yet completed the entire first major chapter of his cultivation, his strength had already increased by more than five times the enhancement effect described in the secret cultivation method.
This terrifying strength meant that he could surpass even pure-blooded Senju direct descendants just with his raw power.
Even though he had not witnessed Senju Hashirama's strength at the same age, Uchiha Tenxiu still did not believe his own strength was inferior to Hashirama's.
"Although in the original plot, Senju Hashirama's weapon was a large, door-like greatsword, which looked heavy, my strength comes from daily, dedicated Taijutsu training," Uchiha Tenxiu mused, his heart filled with unyielding confidence.
"Even as a Chunin, I could rely on my Taijutsu to contend with Ninja of the same rank, not to mention how my aptitude was further unearthed after the Jonin limit was broken."
"Now, with the cultivation of the Refining Essence chapter, my physical foundation and limits are constantly increasing."
"In terms of the Ninja World's explanation, it means my Yang Release potential is increasing, constantly enhancing my physical strength."
"Aside from all that, simply because my physical strength has become powerful, my Chakra volume has surged again, allowing my strength to transcend my own Ninja rank, making me equivalent to what the Ninja World calls an Elite Jonin!
After all, with such a powerful Chakra advantage, I can completely use a massive amount of Chakra to deplete the enemy's Chakra and win."
"Not to mention, in terms of physical aspects, with the overall increase in strength, speed, Chakra control, and the increase in both the total volume and quality of Chakra, all my abilities have been further enhanced.
Compared to an Elite Jonin, the only things I lack are combat experience and Ninja qualities."
Uchiha Tenxiu compared his own strength, and finally felt a slight sense of security.
Elite Jonin.
And not just any Elite Jonin.
This could barely be considered a basic standard in the Ninja World.
At least, if any sudden incidents occurred,
while the Ninja World's experts were still gathered in their own Villages, 99% of the Ninja appearing outside would clearly not exceed this level.
Therefore, as long as the Ninja World was not at war,
Uchiha Tenxiu could slightly expand his range of activity without worrying about causing trouble.
...
This afternoon,
Uchiha Tenxiu was about to complete the final breakthrough in his cultivation of the first chapter of the cultivation method.
All of his physical energy continuously converged within his body.
As he cultivated, a unique vision, different from the Sharingan's ability to peer into the body's internal Chakra, appeared in Uchiha Tenxiu's eyes.
It was another form of internal vision from a different system, allowing him to constantly observe a series of changes within his body—flesh, bone marrow, and even meridians and acupoints.
Any adverse effects that arose during cultivation could be easily found.
"With this, there will be no more danger in my physical training," Uchiha Tenxiu thought to himself, understanding the power of this internal vision even more.
Among other things, the ability to constantly regulate his body, perform various forms of recuperation and repair, was something the Ninja World could not achieve.
Therefore, he would not end up with a body full of injuries from desperate training, like others, which would not only prevent strength growth but also carry various risks of regression.
Similar to Might Dai and Might Guy's insane training in the original plot, Uchiha Tenxiu could only deduce that they were naturally suited for Taijutsu, but unfortunately, such training still carried risks.
It could only be said that even with various hidden injuries, they were still able to reach such a level.
If those hidden injuries didn't exist,
perhaps they could have reached an even higher level.
"It's a pity, I don't know where such people are cultivating in the Village right now.
Hmm, I'll see if I have a chance to trick them over later.
If not, then so be it!"
Uchiha Tenxiu thought to himself.
He pushed these thoughts out of his mind.
And entered meditation again.
As a Ninja, Uchiha Tenxiu had long been accustomed to quickly completing this process through cultivation.
Whether it was entering a meditative state, meditating, or perceiving his own will, he excelled at all of it.
He also gained a passive ability: when his thoughts were chaotic, he could quickly calm his mind.
An hour later,
with a 'whoosh' of exhaled breath, Uchiha Tenxiu slowly opened his intelligent eyes, perceiving everything around him.
The Refining Essence chapter was perfectly completed.
"It's finally done!" Uchiha Tenxiu sighed deeply, a look of immense satisfaction in his eyes.
With the completion of the four stages of the Refining Essence chapter, Uchiha Tenxiu thoroughly refined his own body, absorbing a large amount of resources and nutrients externally to enhance his physical potential, and internally, through a series of cultivation, all the originally undeveloped power was developed, allowing him to integrate all the strength of his body with every move.
Such an application of power made Uchiha Tenxiu thoroughly understand that he was no longer like the Ninja of the Ninja World who relied solely on Chakra for combat, becoming vulnerable once their Chakra ran out. Instead, he could truly engage in basic combat even without using Chakra.
He could fight for several days strenuously relying solely on his body, just like people in the Pirate World.
"To this extent, Senju Hashirama and Uchiha Madara's battle in the Valley of the End also lasted three full days before they were exhausted, depleted of resources, and ran out of Chakra! While I might not yet compare to them in terms of Chakra, in terms of physical power application, I am no worse than either of them, and might even surpass them."
Uchiha Tenxiu analyzed clearly. In fact, Uchiha Tenxiu's conjectures were not exaggerated.
"Indeed, the completion of this first chapter brought a nine-fold increase in physical strength, just as I thought!" Uchiha Tenxiu revealed an 'as expected' expression.
At this point.
While Uchiha Tenxiu was overjoyed, he also couldn't help but calm down and take stock of the abilities he gained from this cultivation.
His physical strength increased by more than nine times.
His Chakra also surged by at least nine times.
His spiritual aspect also increased slightly by ten percent.
As for the others, in the four small steps of this first chapter of Refining Essence, there were auxiliary products, passive abilities gained through step-by-step control of his own body.
"Hmm, if I were to describe it using words from my previous life, it would be the complete integration of the body's strength, allowing the body to be used for attack, defense, and other abilities even without using Chakra. If I had to name these four stages."
"Then, they would be Ming Jin, An Jin, Hua Jin, and Dan Jin!" Uchiha Tenxiu thought this way, not that these four names were actually written in this first chapter, but that the path of cultivation is inherently like this; those who pursue the path to its end arrive at the same destination.
Even different cultivation systems, regarding the ultimate outcome of the stages in cultivating the body, are consistent.
For example, according to the division of the four small stages of Refining Essence in the cultivation method: The first stage, being able to integrate one's own physical strength and unlock the body's shackles, results in a doubling of strength. In the context of urban novels with a national martial arts worldview, this is Ming Jin.
The second stage. Being able to slowly increase one's physical potential and continuously unearth more power, and apply this power subtly, like striking through a mountain. In the national martial arts worldview, this is the so-called An Jin application.
The third stage is to fully integrate the body's strength, continuously permeate the entire body, enable internal vision, and constantly regulate internal organs, bone marrow, and other parts. Furthermore, the body's entire strength can be applied to any part of the body; fingers, hair, and skin can all emit power for attack. In the national martial arts worldview, this is the so-called Hua Jin application.
As for the fourth stage, this is integrating all of this power into one, embracing simplicity and maintaining focus, which means continuously refining one's essence, qi, and spirit to a single point, constantly nourishing the Dantian. It is a transitional step, and the next step is to open the Dantian and enter the so-called Qi Transformation stage. In the national martial arts worldview, this is the so-called Dan Jin.
However, the abilities manifested in these four stages are merely passive aspects of the so-called Refining Essence chapter, whereas in the national martial arts worldview, they are treated as the primary focus of cultivation.
After all, in an environment without any extraordinary energy, these things that extraordinary individuals disdain to explore are already techniques that ordinary people greedily pursue.
And for himself, they were quite useful.
Not to mention himself, even others in the Ninja World, as long as they were told the secret, could still learn them.
In Uchiha Tenxiu's conjecture, perhaps in the Ninja World over many years, it was not that no one had noticed this point.
It's just that pursuing this path further seemed relatively useless and wouldn't be a focus for Ninja.
After all, an ant, even if it could exert ten thousand times its strength, still couldn't contend with a human.
And a lion, even if its strength only increased tenfold, could easily dominate the entire forest.
These basic passive abilities could be easily simulated in any world, yet no one bothered to explore them.
The main point is this.
Even with the talent of Ninja, achieving these four passive abilities through deliberate cultivation would not be accomplished in a short time. He, on the other hand, because he had this cultivation method, could directly follow the instructions, clearly understanding the entire cultivation route, and thus passively acquired these abilities.
Meanwhile, Ninja in the Ninja World only needed to spend a month refining Chakra to instantly gain superhuman strength.
Comparing the cost-effectiveness like this.
Who would choose to slowly forge a path on a desolate ruin, heading towards the unknown?
Ninja are not fools!
