My "Katyusha Rocket Launcher" is Out

Elder Keimei stood up to report the intelligence he had gathered, performing hand seals toward the center of the round table.

"Release: Sealing Scroll."

When minor conflicts broke out between the Uzumaki Clan and Kirigakure, our Uzushiogakure shinobi were ambushed due to their confusion regarding the sea and the terrain, paying a price in blood.

The First Uzukage immediately took this seriously, and what he brought out now was a summary of the geography of the Land of Whirlpools, researched and created by the First Uzukage himself.

He used clay to craft an intricate battlefield model, with the sea, Uzushiogakure of the Land of Whirlpools, shortcut passages, and Kirigakure of the Land of Water across the ocean all represented in different colors.

He used clay-fired figurines of various forms to represent key figures from both sides, among which was a small figurine of Uzumaki Shori.

"Second Uzukage, in this model, the Land of Whirlpools is surrounded by water on all sides. Kirigakure is gathering at the border of the Land of Water, preparing ten large sailing ships and mobilizing over four thousand shinobi. They will finish assembling in about four days."

"Our Uzumaki Clan can only mobilize eight hundred shinobi. We do not have large sailing ships, and the Land of Whirlpools is relatively close to the Land of Fire."

"Our small fishing boats are perfectly adequate for our daily comings and goings, but because the Land of Whirlpools is an island nation and we have constant small-scale conflicts with Kirigakure, we also have three hundred medium-sized fishing boats. If we pack them, each can hold fifty people."

Uzumaki Shori studied the terrain model, never expecting his father to have drawn up such a decisive tool. The Uzumaki Clan of the Land of Whirlpools could mobilize eight hundred shinobi.

To the left of the Land of Whirlpools is the Land of Fire, which is close; to the right is the Uzumaki Clan's enemy, Kirigakure, which is quite far away. It takes one day to travel by boat from the border of the Land of Water to the Land of Whirlpools.

The area is filled with islands, reefs, and treacherous currents; the terrain is complex and the distances between them are vast. We must absolutely not bring the war onto land. The Land of Whirlpools is flat as a plain; if Kirigakure successfully lands, we will have failed.

We have so many fishing boats—it can only be said that heaven is helping us. This terrain model is so detailed it is worth a thousand shinobi. There are still two thousand two hundred enemy shinobi left to deal with. I closed my eyes to meditate, hoping for a brainstorm.

"Elder Keimei, besides the shinobi, how many more people can we mobilize from the Uzumaki Clan? Now is the time for the whole clan to work together."

Uzumaki Shiro's expression was grave, the murderous aura on his body drifting outward as he clenched his fists.

"Second Uzukage Shori, I do not agree with sending people without chakra to the battlefield. Against a genin, ordinary people have no power to fight back until the opponent's chakra is exhausted; they can only be used as target practice."

The atmosphere in the Uzukage Hall grew tense. Uzumaki Shori signaled for everyone to remain calm, then demonstrated a sealing jutsu to the captains and elders with great confidence.

"Sealing Scroll: Chakra Capacitor."

Using a sealing scroll to seal chakra—for Uzumaki Shori, who had just leveled up his sealing jutsu, he only needed to combine the knowledge in his mind to easily create technology from a later era.

A chakra capacitor can store the ninjutsu of the caster inside a scroll. Once successfully stored, it can replicate the power of the caster.

When it is time to attack, one only needs to make contact with the sealing practitioner to release the ninjutsu without needing one's own chakra.

Of course, Uzumaki Shori's current sealing level is not high enough to store ninjutsu; he can only store elemental chakra.

The captain of the Sixth Guard, Uzumaki Sasuke, was deeply passionate about sealing jutsu. The First Uzukage had handed over all the Uzumaki Clan's sealing techniques to him for research.

He looked forward to researching a ninjutsu on the same level as the "Dead Demon Consuming Seal," so that the caster would not need to sacrifice their life to the Reaper.

Staring at the sealing jutsu performed by the Second Uzukage Uzumaki Shori, he was deeply shocked. This was a sealing jutsu the Uzumaki Clan had never performed before. His scalp tightened and his whole body trembled; Uzumaki Sasuke took a deep breath to calm himself.

"Second Uzukage, please entrust this sealing jutsu to me. I will surely be able to summarize an even more powerful sealing jutsu."

Uzumaki Shiro watched the Second Uzukage's sealing jutsu, not understanding what this technique had to do with the Uzumaki clansmen. Ordinary people only have a small amount of chakra in their bodies.

Regarding the scrolls that could currently only store elemental chakra, their existence made no difference to them at all. He hesitated, wondering whether he should speak up.

"Our Uzumaki Clan has twenty-one thousand people, including two thousand eight hundred elderly and three thousand five hundred children."

"We can assemble a force of fourteen thousand. Although it looks like we have more people than Kirigakure, our combat power is not a match for them."

At this moment, after Uzumaki Shori created the chakra capacitor, his thoughts were different from everyone else's. In this world of shinobi, everyone treats chakra as a means to use ninjutsu. I come from the Blue Star; I can combine technology and chakra very well.

In my view, the principle is the same as an explosive tag. We can make a quiver, use the "Earth Release: Hardening Technique" to harden it, and also manufacture warheads equipped with large amounts of gunpowder and metal fragments.

Place the sealing scroll into the quiver, fill the inside with gunpowder and secure it. Ordinary people only need to make the quiver, gunpowder, and metal fragments, while the shinobi sealing team handles the assembly.

The fuse conducts chakra, drawing out the fire-attribute chakra from the scroll to detonate the gunpowder inside the quiver in stages. The collision of the springs inside the quiver causes the fire-attribute chakra within the rocket to strengthen the power of the gunpowder, which in turn detonates the reinforced gunpowder to convert it into kinetic energy.

The rocket launches into the air, the second stage of the explosion begins, and it accelerates forward, bombing along the designated route.

When the time comes, we will mount these rocket launchers onto our fishing boats. The rocket launcher will use twenty-four I-beam launch rails, arranged in two staggered rows, twelve in each row.

I name this the maritime "Katyusha Rocket Launcher."

"Listen to me first," Uzumaki Shori responded.

As he spoke, Uzumaki Shori drew the blueprints for everyone and explained the parallel wiring diagrams for the rocket launchers.

"Everyone, this is the secret of our Uzumaki Clan. We will rely on this secret weapon for this naval battle."

"Now, recruit the entire clan to manufacture the rocket launchers. Shinobi will use ninjutsu to accelerate the completion. The enemy needs four days to assemble; we will set out to ambush them in the archipelago halfway. We only have three days—half a day to set out, and half a day to set the ambush."

Elder Keimei watched the people present in high spirits, but he did not feel very happy himself.

Yes, using rocket launchers to defeat opponents from a distance is indeed worth rejoicing over, but how many can actually be manufactured in three days?

The quantity might barely be enough to deal with chunin and genin, and it could cause some damage to jonin, but it would be useless against top-tier experts.

The number of Kirigakure shinobi is greater than ours, and the rocket launchers only serve to bridge the gap for the shinobi at the bottom of the pyramid.

The Mizukage, the Seven Ninja Swordsmen, the Yuki Clan head, the Kaguya Clan head—how are we to deal with these top-tier experts?

I cannot dampen the morale any further now.
