The Mysteries of Ninjutsu

After venting the joy in his heart, Kanna stomped his feet to soothe the stiff muscles in his legs.

When transferring via the Flying Thunder God, the momentum and kinetic energy of the user are preserved; it can be viewed as moving a distance in a vacuum. Of course, the time consumed is infinitely close to zero, so Kanna's feet were quite numb after landing.

After testing the ninjutsu, it was time for a summary. Kanna pondered the following points.

First, Kanna was naturally concerned about the issue of chakra. If his current chakra capacity were counted as one hundred points, then throwing a kunai would only consume a tiny bit of stamina; the sealing technique required to prepare the technique—etching the space-time coordinates onto a kunai or other object—would consume about ten points; opening the void curtain to create a "space-time gate" barrier technique would consume about twenty points; seeing through the void barrier would be another ten points; and finally, using the Substitution Technique and Body Flicker Technique to achieve instant movement would consume about thirty points.

In other words, the procedure for the Flying Thunder God is: first carve the coordinates, then see through the void, and finally pull open the space curtain for instant movement, consuming a total of about sixty points of chakra—equivalent to more than half of Kanna's total.

Of course, the aforementioned sealing techniques, barrier techniques, Substitution Technique, and Body Flicker Technique only serve as the underlying concepts for the Flying Thunder God; the technique itself has already been integrated and mastered, forming a different system—that is, the common space-time ninjutsu.

The power of the Flying Thunder God is indisputable. After the successful experiment, it has rightfully become Kanna's trump card and life-saving technique. Unfortunately, his chakra is still insufficient; he can only use it once in a skirmish. If he overdraws, perhaps he could manage a second time.

The second point is that although Kanna did indeed analyze the Flying Thunder God, the problems are also obvious: how the technique is used still depends on the individual. Just like the Fourth and Second Hokage, who only need an instant to mark space-time coordinates, Kanna still needs to paint and carve them stroke by stroke. Without extensive practice, the Flying Thunder God can only serve as an escape technique. To achieve the level of the Fourth Hokage, who could kill dozens of ninjas in the span of a breath, Kanna's neural reaction speed is still far behind.

The final point can be considered an extra surprise. After using the Flying Thunder God, Kanna felt that he had gained a tiny bit of insight into the mysteries of space. Of course, it was only a tiny bit. It's like a construction worker catching a glimpse of a master's work and thinking, "Oh, so that's how this building can be constructed," but if you actually asked him to design one, that would be a joke.

Regarding this, Kanna still had self-awareness. As a mere genin, being able to experience the feeling of traversing space ahead of time is already a great stroke of luck; he cannot ask for too much. Moreover, with Kanna (the system/AI) present, there will be a constant stream of ninjutsu for him to learn and contemplate in the future. The most important thing right now is to take it one step at a time and make steady progress!

Another month passed. During this time, Kanna thoroughly traversed Kirigakure. It was simple: he asked his mother to buy a batch of wooden kunai for practice, carved his coordinates on them, walked to a high place, tossed one toward a desolate area, moved to it, rested for twenty minutes to replenish his chakra, and then continued his journey.

Major buildings, streets, mountains, rivers, and the seaside—aside from areas marked as restricted zones, Kanna had placed his coordinates in every corner of Kirigakure within that month.

After possessing this technique, Kanna finally experienced the realm of the Fourth Hokage. Just like now, he could sense every corner of the village; as long as he wished, he could instantly move there. It gave him the feeling that although the world is vast, he is omnipresent.

I am omnipresent, I am everywhere, and the world is but a ruler in my heart. With this realization, how could one's mind not be broadened? How could one's spirit not be elevated?

Kanna had a vague feeling that high-level ninjutsu like the Flying Thunder God not only manifests its power in combat but also has a subtle influence on one's spiritual realm.

The Flying Thunder God is about the vastness of the world being mine to traverse, with the ends of the earth only a step away; that is why Minato Namikaze's spirit was so dashing. Following this logic, what about other ninjutsu?

Shinra Tensei is about being untouchable by all laws! Repelling all demons! Being the only true god between heaven and earth! Does Nagato's god-like mental state have anything to do with this technique?

Hell Stab: One-Finger Nukite is about piercing everything! Tearing through everything! Moving forward without hesitation! Nothing under heaven can block it! Does the fierce drive of the Third Raikage, who dared to engage in hand-to-hand combat with Tailed Beasts, stem from this?

The Yin Seal is about gathering essence, energy, and spirit at the center of the brow, returning to the origin, and restraining blood, energy, and mind. Aside from her hemophobia, is the later decadence and self-abandonment of Tsunade also related to the Yin Seal?

Amenominaka is about controlling space-time and ruling over thousands of universes. Does Kaguya Otsutsuki's domineering ambition to destroy the world and reshape the cosmos stem from the influence of this technique?

Whenever Kanna thought of these things, he deeply felt that this world was far from as simple as he had seen in his previous life. A real world must have its own unique "science." Those high-level ninjutsu must contain the creator's understanding of heaven and earth and their exploration of all things. Learning these ninjutsu is equivalent to comprehending their Ninja Way and their spirit.

After a month, Kanna had gained a lot. His daily chakra refinement lessons allowed his chakra levels to grow steadily. Although it wasn't as rapid as when he first broke through to chunin, it was still solid growth. His Flying Thunder God practice gave him major breakthroughs in chakra circulation, control, and his understanding of the Body Flicker Technique. Consequently, after receiving his mother's guidance on tree-climbing and water-walking, he naturally mastered these two mandatory courses.

Furthermore, under the daily practice of the Flying Thunder God, Kanna's mind became increasingly open. With the vastness of the world accessible through human effort, what else was there to be troubled by?

With a refreshed spirit, his chakra cultivation speed naturally did not lag. Kanna practiced until he forgot to eat and sleep, reaching a state of pure contentment. He enjoyed the beauty of progress and was genuinely proud of his own efforts.

Thus, on the first day of December, Kanna had saved up enough for ninety-one lottery draws and could once again draw an S-rank ninjutsu.

Having felt the mysteries of the Flying Thunder God, Kanna no longer looked down on low- or mid-level ninjutsu. Even if high-level ninjutsu weren't very practical for him right now, he was seeking the Ninja Way—the principles of heaven and earth. If he understood the truths of the world, would he still fear that his combat power wouldn't improve?

Following Kanna's mental command, a massive stream of consciousness instantly poured into his mind. Having just "glanced" at the name of this new ninjutsu, Kanna's expression turned solemn.

Although the Flying Thunder God is extremely obscure, it is not a Kekkei Genkai. But what he had just drawn was a ninjutsu that only the most top-tier bloodlines could use.

Deva Path: Shinra Tensei!

(I personally feel my writing style is indeed better than when I was writing Great Demon King, what do you all think? Also, the relationship between ninjutsu and state of mind in this chapter is pure nonsense; if there are any similarities, consider it me plagiarizing.)
