Destructo Disc, Divine Wind Sword, and Hidden Thunder Sword

The foundation of this set of Lightning Release Nintaijutsu was undoubtedly based on the "Thunder Motion Fist" entry he had pilfered from the Cloud Village.

"Thunder Motion Fist" focuses on training the meridians and acupoints of the upper limbs, allowing the hands to unleash power far exceeding the norm after prolonged stimulation by lightning.

Once a practitioner has mastered "Thunder Motion Fist" and passed the assessment at Wulei Temple in Cloud-Thunder Gorge, they are granted the opportunity to be taught the "Lightning Armor."

"Lightning Armor" is not the "Thunder God Armor" used by the successive Raikages; there are significant differences between the two.

"Lightning Armor" can only develop the meridians and acupoints of the entire body to rapidly improve physical fitness; it still falls far short of condensing a Lightning Release Chakra Cloak to achieve astonishing defensive capabilities.

According to the publicly circulating knowledge in the ninja world, one must undergo thirty-six days of heavenly lightning infusion at Wulei Temple in Cloud-Thunder Gorge to thoroughly purge the body of impurities with heavenly lightning energy before one can cultivate a flawless chakra cloak.

Of course, according to the ancient records Touma found from Orochimaru, the chakra cloak of the "Thunder God Armor" can only be successfully cultivated at a specific forbidden zone within Cloud-Thunder Gorge.

Away from that training ground with its unique environment, even with an ample supply of secret medicines, the Yotsuki Clan has produced very few users of the "Thunder God Armor."

Orochimaru speculated that the training ground is likely situated atop a massive magnetite vein. The unique magnetic field there can precisely weaken the power of the heavenly lightning while protecting the human body's own bio-magnetic field, which is sufficient to allow the practitioner's body to enter a cycle of repeated destruction and reconstruction, rapidly strengthening the physique.

Of course, there are ways to simulate such a magnetic field; as long as one possesses the accurate magnetic field structure, it is not difficult to replicate with the technology Orochimaru currently commands.

In fact, when he was bored, he even proposed a magnetic detector capable of intuitively displaying the composition of a magnetic field and drew up the structural diagrams.

However, Orochimaru did not continue this project because the so-called Cloud-Thunder Gorge training ground has always been under the protection of Wulei Temple.

The number of warrior monks at Wulei Temple is not much fewer than those at Hosen Temple in the Land of Fire. Trying to force one's way into Wulei Temple would be less efficient than storming the Raikage's office to see if there are any archived records of the magnetic field structure there!

One must know that Wulei Temple has suppressed both the Two-Tails Matatabi and the Eight-Tails Gyuki, and even now, whenever the Cloud Village wishes to rotate its jinchuriki, they must request the assistance of Wulei Temple.

Therefore, Orochimaru did not value such a research project with a severely unbalanced cost-to-benefit ratio, and it naturally ended up gathering dust among his old papers.

However, the fact that the research project did not proceed does not mean the preliminary research was without value.

Regardless, Orochimaru's study on the effects of different electrical potential differences at various acupoints was enough for Touma to perfect his "Thunder Motion Fist."

In particular, Orochimaru had deeply analyzed the development notes on the "Sword of the Thunder God" left behind by Senju Tobirama, summarizing the nature transformation of Lightning Release chakra and the nature transformation of chakra outside the body recorded therein.

Using this data, Touma used "Thunder Motion Fist" as a foundation to deduce the further B-rank "Lightning Release: Hidden Thunder Sword," the A-rank "Thunder Roar Burst," the A-rank "Lightning Release Chakra Mode," and he even found some clues regarding the attribute-based transformation of Lightning Release.

Among them, the "Hidden Thunder Sword" is the counterpart to the "Divine Wind Sword"; both involve condensing a high-speed rotating chakra shuriken in the hand and applying attribute transformation to it.

This chakra shuriken is as thin as a cicada's wing; not only can it be held, but it can also be launched to track and attack targets, bearing a striking resemblance to the "Destructo Disc" used by Krillin in the Dragon Ball world.

It is not that Touma is incapable of completing the "Rasengan," but the "Rasengan" has very low utility for him and is somewhat too chakra-intensive.

According to Touma's previous attempts, compressing and condensing a stable, standard-sized "Rasengan" would directly consume one-fifth of the chakra in his body.

His chakra reserves are already considered high among ninjas of his age; even Kushina Uzumaki, who is two years his junior, does not have much more chakra than he does.

Touma is certain that Naruto dared to use the "Rasengan" as a standard tactic in the Shippuden era because, on one hand, his own Uzumaki physique had matured, maintaining his chakra levels at an extremely high level, and on the other hand, it is likely that the Eight Trigrams Seal on his stomach could passively extract and utilize the Nine-Tails' chakra.

Otherwise, using the "Rasengan" and "Multiple Shadow Clone Technique" at such high frequencies would have killed him long ago.

The "Destructo Disc" developed by Touma only consumes one-tenth of the chakra required for a "Rasengan" of equivalent destructive power.

Because the "Destructo Disc" only needs to maintain longitudinal compression force and does not require the omnidirectional compression force of the "Rasengan," there is naturally a nearly tenfold difference in chakra consumption.

Furthermore, the "Divine Wind Sword" and "Hidden Thunder Sword," which are formed after the "Destructo Disc" undergoes attribute transformation, also possess special abilities due to their high-speed morphological changes.

The "Divine Wind Sword" can cut through anything; even Fire Release defensive ninjutsu that are elementally superior to it are sliced in two, and it does not trigger the large-scale explosions characteristic of the "Wind Release: Rasengan."

The "Hidden Thunder Sword" can become completely invisible, shielding itself even from sensory techniques, because the high-speed rotating current forms a strong magnetic field around it. This magnetic field can not only deflect light in a straight line but also deflect the chakra radiation of sensory techniques!

And now, facing Kamikawa Ryuhei, Touma has a "Divine Wind Sword" and a "Hidden Thunder Sword" gathered in his left and right palms, respectively.

Oh right, this person should no longer be called Kamikawa Ryuhei; he had already told Touma his name was Hozuki Mitsuki.

Revealing his true identity, Hozuki Mitsuki also brought out his weapon: the "Twin Blades: Hiramekarei," one of the Seven Ninja Swords of the Mist.

It seems that in order to make the Hozuki Clan willing to send Hozuki Mitsuki to carry out the assassination mission, the Mizukage directly granted the Hozuki Clan the right to use the ninja blade.

Touma quickly used the "Substitution Ground-Shrinking Technique" to move to Hozuki Mitsuki's left side, and the "Divine Wind Sword" in his left hand slashed toward the arm holding the blade at an extremely tricky angle.

Hozuki Mitsuki also sensed the sharpness of the "Divine Wind Sword" and hurriedly poured chakra into the "Hiramekarei," ejecting it through the air holes on the blade to push his arm to the other side, dodging the "Divine Wind Sword."

But before he could stabilize his stance, the "Hidden Thunder Sword" in Touma's left hand had already been launched; after circling him for half a turn, it vanished into the air.

Hozuki Mitsuki initially thought the attack had missed, but the next second, he felt a deep bloody gash cut across his back.

What was fatal was that his "Hydrification Technique" had failed to activate at all; clearly, the previous move had utilized Lightning Release nature transformation, causing his body to enter a state of temporary paralysis, and the "Hydrification Technique" had been completely nullified.

Touma pressed his advantage. After consuming the "Divine Wind Sword" in his hand, he clenched his fists, utilized "Thunder Motion Fist," closed in on him, and unleashed a flurry of rapid-fire punches.

It must be said that with the speed boost from "Thunder Motion Fist," the rapid-fire punches were so fast that only blurry afterimages could be seen; it was impossible to distinguish the number of fists.

Although Hozuki Mitsuki had suffered heavy internal injuries, under the suppression of the lightning attribute, all his methods based on the "Hydrification Technique" were restricted.

Even if he could create a water clone to put distance between himself and Touma and gain a few seconds of breathing room, he would be instantly closed in on by Touma's "Ground-Shrinking Technique" and forced to endure another round of lightning-infused punches.
