The mixture of physical energy and spiritual energy produced by the 130 trillion cells in the human body was called "stamina." "Stamina" was the foundation for using Taijutsu.
Stamina was transformed into Chakra within the body. Mixing "these two elements evenly"—spiritual energy and physical energy—created Chakra.
After extracting Chakra, ninjas could use "techniques" through "Hand Seals." These were ninjutsu.
The Chakra Extraction Technique was the most basic Chakra Extraction Technique. From now on, you would have to include Chakra extraction training in your daily routine.
Might Guy, holding a scroll, said this to Haku and Duy.
But remember, you must control the amount of time you spend practicing the Chakra Extraction Technique each day. It must not be too long. Excessively forcing your body's cells was bad for you.
Haku knew what Might Guy was talking about. In the Naruto World, the stronger a ninja was and the more intense the battles they fought, the shorter their lifespan.
The average lifespan of ninjas was not even forty years, because every time they extracted Chakra, they were forcing their body's cells.
Young men! Let your youth shine!
Listening to those familiar words and watching the two of them sob with their heads in their hands, Haku silently retreated to the corner of the training ground. He sat on the ground, closed his eyes, and began meditating.
With his eyes closed, Haku began to sense his physical energy and spiritual energy.
As a transmigrator, Haku actually knew the principles behind Chakra. At the same time, he also knew about ki from the Dragon Ball world.
Ki was the most fundamental energy within a living being. Through cultivation or training, one could freely manipulate this energy.
In theory, Chakra and ki were both produced within the body. There was no reason why one would harm the body while the other could nourish it, promote the body's evolution, and even extend one's lifespan. There had to be some reason for this that he did not yet know.
However, as someone with Saiyan blood, Haku found ki cultivation to be the better cultivation system for him.
Aside from its higher upper limit, there was also the enhancement provided by his bloodline.
However, ki seemed to be more difficult to master. Apparently, one needed a Combat Power of over 100 to control it.
Whatever. He would extract Chakra first. He could not neglect his comprehension of ki, either.
Having thought this, Haku stopped dwelling on it. With his eyes closed, he began concentrating on sensing his physical energy and spiritual energy.
He meditated with his eyes closed, sensing every part of his body and trying to feel every subtle change within it. In the end, all he sensed was emptiness. He could feel nothing at all.
Spiritual energy, on the other hand, was different. Perhaps because he was a transmigrator with a mature soul, and because he had been baptized by the information explosion of his previous world,
he easily sensed his spiritual energy. It seemed like a weak mass of energy that could change according to his will. At one point, Haku even thought he might be able to control it and move objects.
When he had watched the anime, the ninjas extracted Chakra simply by closing their eyes. They could even erupt in battle and forcefully extract massive amounts of Chakra. It all looked quite simple.
But now that he was actually doing it himself, Haku understood how difficult it was. Many things in the anime had been glossed over, without being explained clearly.
From now on, he would have to think more carefully before acting. He could not simply act based on the results shown in the original work.
While Haku was still striving to sense his physical energy, Might Guy suddenly called a halt.
Haku, you've been meditating for two hours today. That's about enough. Meditating and extracting Chakra for too long every day isn't good.
But I still haven't managed to extract Chakra. I can't even sense the existence of physical energy yet. Haku still wanted to meditate a while longer. Perhaps then he would be able to sense his physical energy.
Father! I haven't succeeded in extracting it, either!
Duy added from the side.
That's normal. You've only just begun learning the Chakra Extraction Technique. Anyone who can extract their first wisp of Chakra within a week is a genius. Normally, it takes a month or even several months to succeed.
You still want to keep extracting it? I'm truly moved. This is youth!
Once again, there was that familiar thumbs-up and flash of dazzling teeth.
When Haku saw Guy and Duy embracing and sobbing, he silently turned around and began that day's training.
Father, Haku went off to train by himself. This is youth shining! Let's go, too. We can't waste our youth.
Seeing Haku go running, Duy said this to Guy with shining eyes.
Good! As expected of Haku! Let's make our youth shine, too!
As he spoke, he led Duy after Haku.
The figures of the one adult and two children grew farther and farther away, while the village gradually began to stir.
After that, Haku, Guy, and Duy began their training: two hours of meditation every morning, followed by physical exercise.
Just like that, another month passed.
Take a deep breath. Inhale slowly, allowing the air to fully fill your lungs and giving every cell in your body an ample supply of oxygen, preparing to stimulate your physical energy; then exhale slowly, expelling the stale air from your body. With each breath in and out, gradually relax your body and enter a state suitable for extracting Chakra.
