After settling the earlier matters, Kurozai pulled out a scroll from within his robes. Glancing toward the others, he said, "I'll need a more spacious place to unseal the money."
Everyone understood immediately. In the world of Naruto, even something as simple as a bowl of ramen could cost anywhere from 20 to 60 Ryo. Ten billion Ryo, in physical cash, weighed well over a hundred tons, far more than any small room, especially one cluttered with furniture, could possibly hold. Although ninjas could store such amounts compactly using sealing scrolls, the Daimyo's Mansion and its financial department would never accept their national funds in sealed form. Storing money inside scrolls made it far easier to steal, harder for ordinary officials to handle, and more troublesome for verification. They needed the cash out in the open and counted manually.
Soon, the group moved to a large storage hall normally used for grain and logistics. Kurozai stepped forward, holding the specially prepared scroll. He wove several hand signs in a precise sequence while channeling chakra into it. This scroll was crafted with a seal that detected the user's chakra signature and the exact order of signs, confirming the identity of the one unsealing it.
With a loud poof, smoke erupted. As it dispersed, mountains of money appeared stacked from the ground up, bundles upon bundles of bills, the highest denomination being a simple 1,000-Ryo note. Though promissory notes and joint banking methods existed between the Five Great Nations and others for storing and transferring currency, these systems were still superficial. The banks could not handle sums as large as ten billion Ryo; even with the most extreme effort, it would take months for them to gather such an amount in physical forms, after all, rogue ninjas could rob them. Due to strict safety and distribution protocols, banks weren't capable of matching the financial needs of entire countries at this scale. Banking, while convenient for merchants and minor transactions, still wasn't widely used for major state finances.
Every nation had its own internal financial institutions, and even the ninja villages, departments, and organizations maintained their own storage systems and budgets, like having their own small banks. Although Ryo was a shared currency, it was not jointly managed. Gold reserves, taxes, and the internal economic strength of each country ultimately decided how much money they were able to print and circulate. That was precisely why these ten billion Ryo in direct cash were so valuable and so heavily sought after.
Once the counting was complete and the Daimyo's officials finished their verification, the financial team happily returned to their duties of taking it back to the capital. Everyone then politely escorted themselves out of the temporary treasury area. It was then that the Third Kazekage, along with Chiyo, Ebizo, and several others, personally led Kurozai toward the training grounds. As masters of ninjutsu themselves, they would confirm the authenticity of the S-rank techniques Kumogakure had brought.
Kurozai opened one of the scrolls containing an S-rank ninjutsu and handed it to the Kazekage's group. They gathered around to examine it closely. The technique was titled Wind Style, Erosion Reincarnation Wave, a large-scale ninjutsu consisting of thirty-two hand seals and corresponding chakra route and internal chakra manipulation, created by Ron. At its core lay a unique nature transformation of wind. The dryness aspect, commonly observed in desert winds, had been refined into a specialized alteration similar to a secret technique, hence the word "Erosion." The term "Reincarnation" was chosen not only for its dramatic flair but also to hint at the continuous cycling form required to maintain this technique, which was designed to trap the enemy.
The jutsu, in its most basic essence, resembled a combination of Wind Style Great Breakthrough and Kamaitachi. Great Breakthrough relied on overwhelming pressure to push opponents away, while Kamaitachi emphasized pure sharpness. This new technique demanded the caster release two simultaneous waves of sharp, large-scale wind pressure, an upper wave charged with positive pressure and slicing force meant to push the target and cut the enemy, and a lower wave infused with negative pressure that pulled the target inward, while cutting people also. Together, they formed a massive cyclic wind formation.
To release this ninjutsu, the user had to perform extremely complex internal chakra operations. The wind expelled from the upper section pushed outward with force and blade-like sharpness, while the lower section drew inward like a vacuum. Anyone caught between these two opposing pressure zones would be trapped, their body pulled and pushed at once, slicing winds cutting at them continuously. Even if the enemy had a strong body with defensive chakra or ninjutsu, they would struggle to breathe and move, and the pressures would keep them locked in place. An ordinary, unenhanced body would be instantly shredded.
But the most dangerous element was the dryness. As long as the enemy was exposed to the winds inside the formation, their body moisture would begin to drain little by little. The longer they were trapped, the more their stamina and physical performance deteriorated. This moisture loss wasn't immediately fatal, nor was it overwhelmingly fast, but combined with the countless small cuts from the slicing winds, even a minor wound could become life-threatening. Each open cut accelerated blood loss, and the jutsu's dryness effect would draw that blood out more easily, leaving the victim's body increasingly dehydrated and anemic, usually causing a hypovolemic shock due to lack of blood and a hard time breathing.
This was the terrifying essence of the technique, a prison of wind, pressure, sharpness, and dryness that slowly unraveled the opponent, piece by piece.
