This ninja in Naruto is unscientific

Chapter 49 A Letter from the Land of Rain

The Konoha Police Department, a laboratory that has just been emptied and converted.

The light from the incandescent bulb shone on the lab bench, which was piled high with chakra-conducting metals and various rare materials "brought back" from the Root.

Minato Namikaze leaned against the lab bench, curiously fiddling with a metal tube wrapped with copper coils.

"What are you researching?"

Wearing goggles, Nishikawa Tetsu was carefully handling a lightning-attribute chakra crystal with tweezers.

He straightened up, his eyes becoming sharp and fervent: "I'm using scientific thinking to reconstruct chakra."

"For example, this one."

Nishikawa Tetsu pointed to the coil device in Minato's hand.

"I call it—the prototype of 'Lightning Release: Railgun'."

"Electromagnetic Cannon?" Minato blinked, thinking the name was cool.

"The principle is very simple."

Nishikawa Tetsu picked up a specially made coin, which was mixed with chakra-conducting metal seized from Root.

"Using Lightning Release chakra to generate a strong magnetic field in the coil, and then using Ampere's force to instantly accelerate the projectile. Compared to bullets propelled by gunpowder explosions, this method is silent, flashless, and can easily exceed three times the speed of sound in its initial velocity."

"Minato, give it a try."

Nishikawa Tetsu secured the device to the frame and signaled Minato to inject lightning-attribute chakra.

Although Minato's Lightning Release was not as proficient as his Wind Release, it was sufficient for his experiments.

"Sizzle sizzle..."

As chakra was injected, blue electric arcs lit up on the coils.

"put!"

Nishikawa Tetsu flicked the coin into the track.

"boom!"

A very short, sharp explosion.

The coin traced an orange beam of light in the air, a result of plasma generated by its intense friction with the air.

Fifty meters away, a thick steel plate used to test defensive ninjutsu was instantly pierced.

The cut is as smooth as a mirror, and due to the high temperature, the edges appear to be molten.

"this……"

Shuimen looked at the hole and broke out in a cold sweat.

"This power is stronger than my Wind Release? And the speed is too fast; even the Sharingan might not be able to catch it."

"This is just a prototype." Nishikawa Tetsu recorded the data. "If it can be combined with your Flying Thunder God Technique and launched at point-blank range during teleportation... that would be an absolute kill."

"Besides this, there's also the application of Earth Escape."

Nishikawa Tetsu walked to another corner of the laboratory, where several buckets of gray powder were piled up.

"This is my 'Special Chakra Cement' developed by combining Earth Release chakra nature transformation."

"Once infused with Earth Release chakra, this powder will solidify within three seconds, becoming five times harder than granite. On the battlefield, it can instantly create impenetrable cover, or..."

Nishikawa Tetsu narrowed his eyes: "Used to quickly build defensive fortifications and completely block the enemy's attack routes."

"And water escape techniques."

He then picked up a high-pressure nozzle engraved with miniature sealing techniques.

"The principle of Water Release: Hard Vortex Water Blade is to create a water vortex, but mine is a 'High-Pressure Water Blade.' It uses sealing techniques to compress water pressure to the extreme, and then shoots it out through an extremely fine nozzle. This water stream can cut through steel and is even sharper than Wind Release."

Looking at the room full of "new inventions," Minato Namikaze couldn't help but swallow hard.

"Che, are you trying to turn ninjutsu into a physics lesson?"

"Chakra is a versatile energy source; it's a waste to only use it for breathing fire and water."

Nishikawa Tetsu removed his goggles and rubbed his temples. "What we need to do is create the greatest physical destruction with the least amount of chakra consumed. That's the true essence of 'Scientific Ninja Tools'."

Just as the two were discussing how to miniaturize the electromagnetic gun for portability.

"Bang!"

A puff of white smoke exploded on the lab table.

A little toad wearing glasses—the messenger Kosuke—appeared out of nowhere, carrying a small package.

"Yo, Nishikawa Toru, Namikaze Minato."

Kosuke adjusted his glasses. "A letter from the Land of Rain."

"Oh? Yahiko and the others?"

Minato's eyes lit up, and he immediately put down the parts he was holding.

Nishikawa Tetsu took the letter and opened it.

The letter paper was somewhat rough, still carrying the damp scent unique to the Land of Rain. The handwriting was Yahiko's flamboyant style, but it also included Konan's delicate additions and Jiraiya's bold annotations.

【Che, Shuimen, it's like seeing you in person!】

【Everything's great here! Following the business plan you provided, Che, our penicillin business is booming! Not only are merchant caravans buying it, but even nobles from several neighboring small countries are secretly coming to buy it. We've already used the profits to repair houses in three villages and taken in even more orphans.】

[By the way, I'm now the leader of "Akatsuki"! Although there are currently fewer than twenty people including Jiraiya-sensei, everyone is very energetic!]

The middle part of the letter was written in Nagato's handwriting, neat and strong:

"Teru, you're right, power needs to be controlled. I'm currently learning how to control...that power under Jiraiya-sensei's guidance. It's difficult, but I won't give up. I will protect Yahiko and Konan."

[P.S.: The compressed biscuits you sent last time were awful, but they were very filling. —Nagato]

Finally, there was Jiraiya's bold, flowing calligraphy:

[Hahaha! You two brats have stirred up quite a storm in Konoha! I've heard about it all—the police department reforms, the raid on Danzo's hideout. Well done! But you still need to be careful; Danzo is no ordinary person!]

How's Fugaku's eye? Tell him not to think too much and to focus on recovering.

"I'll be staying here for a while longer. These three little ones are growing faster than I imagined. Especially Nagato... Anyway, I'm leaving Konoha in your care. Don't worry. — Toad Sage of Mount Myōboku"

After reading the letter, the atmosphere in the laboratory became much warmer.

"Looks like they did a good job."

Minato smiled as he put the letter away. "That Yahiko guy is really realizing his dream step by step."

"We have money, food, strength, and the right guiding ideology."

Nishikawa Tetsu carefully put the letter away and placed it in the filing cabinet. "As long as they don't go astray, Akatsuki will become a force that the Land of Rain cannot ignore."

"Oh, right." Nishikawa Tetsuya seemed to have thought of something and pulled a bag out of the pile of "cement".

"Minato, next time you reply to Jiraiya-sensei, take this with you."

"This is?"

"An improved quick-drying cement formula," Nishikawa Tetsu said. "The Land of Rain gets a lot of rain, the roads are difficult to travel, and houses are prone to collapsing. With this, they can speed up infrastructure construction tenfold, although the materials are a bit expensive."

"Infrastructure development?" Minato chuckled, exasperated. "Are you trying to turn the Akatsuki into a construction company?"

"If you want to get rich, build roads first."

Nishikawa Tetsu picked up the prototype electromagnetic cannon, his eyes gleaming with rationality.

"We are engaged in political struggles and an arms race in Konoha, while they are focused on economic development and encircling the cities from the countryside in the Land of Rain."

"Although we are in two different places, we are working towards the same goal—"

"End this chaotic world."

Nishikawa Tetsu inserts a new coin into the coil.

"Alright, let's continue the experiment. We must solve the overheating problem of this coil tonight, otherwise if Fugaku-senpai uses this thing and burns his own hand before killing the enemy, that would be a medical accident."
