"Comrade Fang Tianyi, the experts have made preliminary discoveries regarding the chakra theory you sent back!
The chakra theory states that chakra is extracted from the energy of the human body's 138 trillion cells.
But after comparison, modern ordinary Blue Star humans have an average total of only around 38 trillion cells!"
Was the gap really that enormous? The comparison of those figures made Tianyi's heart jolt.
Commander Tian continued, "The expert team repeatedly analyzed the data and combined it with this world's historical information.
They proposed a core hypothesis: the human physique in your world was affected by the Ancient Divine Tree.
It underwent a fundamental evolution, and both the total number of cells and the latent energy structures within those cells
have become fundamentally different from those of Earth humans. Those additional hundred trillion cells, or their unique cellular structures,
form the biological basis for sensing and producing chakra."
"In other words," Commander Tian concluded,
"Blue Star's current technology cannot make ordinary people develop chakra out of thin air.
The key may lie in studying your biological samples—or rather, the unique biological samples of humans from that world—
to unravel the mysteries at the cellular level."
Tianyi understood. "You mean you need my biological samples? Blood, hair, skin cells, things like that?"
"That's right! If possible, provide as many different types of somatic cell samples as you can to facilitate comparative research.
This is the key to unlocking the physiological basis of chakra, and perhaps even exploring whether specific personnel can develop chakra in the future."
Commander Tian spoke solemnly.
"Understood. I'll prepare them immediately!" Tianyi did not hesitate.
He moved quickly, carefully pricking his fingertip with a clean kunai and squeezing several drops of blood onto a sealed sample strip.
He plucked several hairs with their follicles attached and swabbed the inside of his mouth to collect mucosal cells.
He even carefully scraped off a little skin debris and placed everything into separate miniature sealed bags.
"The samples are ready. Transferring them now." He sent the biological samples over one by one.
"Received. Excellent!" Suppressed excitement came from the command center.
The value of these samples was extremely high.
"Comrade Fang Tianyi," Commander Tian's voice came again after receiving confirmation from the technical department.
"The country will not leave you to fight alone. Given the threat posed by the enemy you are about to face,
we will crack this poison within seven days and produce a preliminary serum.
For now, what do you need? Do you have any special requirements?"
Tianyi thought quickly. What he needed most right now was medical equipment.
"Then prepare a basic set of surgical instruments for me, along with adrenaline, penicillin, and other medicines."
"Received! The list has been recorded. We'll coordinate preparations immediately!" Commander Tian replied swiftly.
Once the supplies had been transferred over, the communication window closed.
Tianyi turned his gaze back to the medical scroll Aoi had given him. Then he would start with the Detoxification Technique.
He sat cross-legged, not rushing to study the hand seals. Instead, he first closed his eyes.
He tried hard to recall the most basic lessons on ninjutsu that Hyuga Tianyi had received at the Ninja Academy.
Fragments of memory gradually became clear. The voice of a stern-faced Chunin instructor seemed to echo in his mind:
"...Hand seals are, in essence, gesture codes used to guide chakra.
Every seal—Rat, Ox, Tiger, Rabbit...—is not arranged at random.
They correspond to the flow paths of chakra through the meridians, as well as patterns of combination.
The process of forming seals is the act of creating a preset track for the invisible chakra energy within your body,
allowing it to circulate and transform according to the needs of a specific ninjutsu.
In the end, it produces the corresponding effect. That is how ninjutsu is released."
"So that's how it is!" Tianyi suddenly understood.
If chakra was compared to an electric current and the meridians to circuitry,
then hand seals were like a precise combination of switches and resistors.
They guided the current through a specific pattern and ultimately lit different bulbs.
That meant learning ninjutsu was not simply a matter of memorizing a few gestures.
More importantly, he had to understand the internal chakra changes each seal guided.
Fortunately, the original owner of this body had a fairly solid grasp of the basics.
He had left behind plenty of muscle memory regarding chakra meridian distribution and basic sensations of chakra flow.
He picked up the scroll and first looked at the basic-level Hemostasis Technique.
Its seals were simple, consisting of only three: Snake, Goat, and Monkey.
A diagram beside the text illustrated the extraction of chakra, its passage through specific meridians in the arm, and its eventual gathering at the fingertips.
There, it would transform into a form of energy inclined toward blood coagulation and cellular activation.
Tianyi held his breath and focused, mobilizing the faint trace of chakra that had only just recovered inside him.
His hands slowly and carefully began to form the seals: Snake, Goat, Monkey.
As he formed them, he concentrated fully on sensing the chakra within his body.
Sure enough! As the hand seals changed, he could vaguely feel chakra being invisibly guided.
It rose from his lower abdomen and surged toward his fingertips along a warm current-like path on the inside of his arms.
The instant the final Monkey seal was completed and his palms pushed forward, his fingertips grew slightly warm.
"It worked!... Though the effect is probably worse than a hemostatic bandage right now.
But I'm on the right track!" Tianyi was overjoyed. He followed the same method and tried the Regeneration Technique and the Detoxification Technique.
The Detoxification Technique's seals were clearly more complex, and its chakra flow paths involved multiple meridians connected to the heart, lungs, liver, and more.
In the end, it had to produce an effect in the palm that could absorb toxins.
It was extremely taxing on both concentration and control.
Tianyi tried several times, but at most he could barely make the chakra travel through the entire route.
He could only create a faint numb, itchy sensation in his palm. He was still far from truly detoxifying anything.
But at the moment he successfully completed the seals for the Hemostasis Technique, Regeneration Technique, and Detoxification Technique
and gained a preliminary understanding of the chakra-guiding intent behind them—
the Book of Ten Thousand Worlds in his clothes grew faintly warm.
Tianyi's heart stirred, and he immediately summoned the panel.
An azure screen appeared, and his gaze swiftly moved downward.
Sure enough, he discovered a new change under [Mastered Skills]!
It had previously contained only:
· Three-Body Technique (Clone/Substitution/Transformation): Beginner · Gentle Fist: Acupoint Strike, Empty Palm · Kekkei Genkai: Byakugan (Incomplete) · First Aid: Intermediate
And now, another line had appeared beneath them:
· Basic Medical Ninjutsu (Hemostasis/Regeneration/Detoxification): Beginner
"So it really works like this!" Excitement flashed in Tianyi's eyes.
"As long as I systematically study and understand a ninjutsu,
or truly grasp the principles of a skill,
it will automatically be recorded on the panel!
It's like an automated progress tracker for skill learning!"
What did that mean? It meant that theoretically, as long as he had a way to study and understand something,
even the most profound space-time ninjutsu or forbidden techniques would be acknowledged and recorded by the panel as long as he could find the right path! It opened endless possibilities for his future growth.
Of course, the prerequisite was that he could come into contact with those advanced ninjutsu.
After his wild excitement subsided, Tianyi calmed down slightly.
The most urgent matter right now was undoubtedly mastering the Detoxification Technique. It was his lifesaver against Hanzo's threat.
"Skill points..." His gaze landed on [Available Skill Points: 2].
Should he directly spend them on the Detoxification Technique? The thought flashed through his mind, but he rejected it.
"The Detoxification Technique is only part of Basic Medical Ninjutsu. Spending points on it alone would be too wasteful.
Skill points need to be used where they can change the situation more significantly."
He began weighing his options carefully.
First Aid was his trump card, the foundation of his survival.
Improving it would certainly make it stronger, but Intermediate was already enough for the camp right now. Raising it further would merely be icing on the cake.
The Byakugan was restricted by chakra and the control of the Caged Bird, and it was sufficient for now.
Gentle Fist was a combat method, but he was taking the medical path.
Besides, he had grenades provided by the country as a trump card, so close combat was not an urgent need for the moment.
Finally, his gaze settled on this attribute.
Ninjutsu—chakra control, understanding of techniques, and casting speed.
Raising Ninjutsu would mean learning any new ninjutsu faster and using chakra more efficiently.
His hand seals would become smoother. This would not only speed up his mastery of the Detoxification Technique,
but would permanently improve his ability to learn any technique that might be useful in the future.
The value was incredibly high! With that thought, he no longer hesitated.
He focused his mind and locked onto [Ninjutsu: 3].
"Invest 1 skill point to increase the Ninjutsu attribute."
The panel flickered faintly, and [Available Skill Points] changed from 2 to 1.
Immediately afterward, the number after [Ninjutsu] blurred for a moment before jumping to 4.
No earth-shattering knowledge flooded into him, but Tianyi clearly felt that something in his body had changed.
When he tried mobilizing chakra again, it seemed... a little more obedient?
It flowed more smoothly, with less of that sluggish resistance.
He picked up the Detoxification Technique scroll again and looked at the complex seals and meridian route diagrams.
The parts that had seemed vague before and required repeated study
now appeared much clearer and easier to understand.
His mind automatically matched the hand seal movements with the chakra flow patterns they required.
He tried forming the Detoxification Technique seals again: Dragon—Rooster—Boar—Snake—Rat.
Though he was still unfamiliar with them, there was less awkwardness, and the absorbing, decomposing sensation gathering in his palm
was also slightly easier to concentrate.
"It really works!" Tianyi experienced those subtle yet tangible changes.
It could not immediately turn him into an expert, but it had undoubtedly accelerated his learning process and reduced the difficulty of mastering the technique.
"One point left. I'll use it when it matters." He then put away the panel.
He looked once more at the Detoxification Technique scroll, his gaze becoming more focused and confident.
The night was still long, and he immersed himself in deeper study and practice of the Detoxification Technique.
Every hand seal and every instance of guiding chakra was more efficient than before.
