This ninja in Naruto is unscientific

At the top of the armory disguised as a sewage treatment plant, three figures were moving slowly like geckos, clinging to the slippery tiles.

Nishikawa Tetsu lay down next to a huge square exhaust vent and felt the powerful suction with his hand.

This is the "air intake," responsible for drawing fresh air from outside into the enclosed underground storage room to maintain a constant temperature and humidity.

"In other words, as soon as I pour the stuff in, it will be evenly distributed in every corner of the entire underground warehouse in about ten seconds."

Nishikawa Tetsu pulled out the canister of a lethal dose of mixed poison and several packets of seemingly harmless silver-gray powder from his backpack.

"Before that, we need to clean our eyes."

Fugaku Uchiha crouched in the shadows at a slightly higher position, his Sharingan locked onto a sentry atop a water tower not far away.

The Rain Ninja was yawning while holding his sniper crossbow, completely unaware that the Grim Reaper was already standing behind him.

"Watergate".

"clear."

Minato Namikaze's figure vanished in an instant.

There was no sound, not even the raindrops were disturbed.

Just one second later, the sentry on the water tower collapsed limply, with only a thin, barely perceptible line of blood on his neck.

Minato Namikaze supported the body, gently laid it flat, and then gave a "safe" gesture to the two people below.

"Cleanup complete. All the hidden sentries at the four corners have been dealt with."

Minato Namikaze used the Body Flicker Technique to return to the ventilation vent, his breathing steady, as if he had just gone for a walk.

"here you go."

Without further hesitation, Nishikawa Tetsu quickly took out his tools and skillfully removed the protective grille from the air intake.

"The first course: a mixture of high concentrations of capsaicin and tear gas."

He turned on the valve of the can, and a pungent red smoke was instantly drawn into the fan by the powerful suction and disappeared into the bottomless pipe.

"This thing will cause the respiratory tract to swell instantly, causing tears and snot to flow uncontrollably, and making them lose the ability to form hand seals and communicate."

"The second dish: aluminum thermopowder and flour."

Nishikawa Tetsu shook the large packets of powder directly into the container.

"This is to give them some warmth."

After doing all this, Nishikawa Tetsu took out a specially modified explosive tag from his ninja tool bag.

He attached the detonator to a timer and then stuck it to the inside of the fan blades.

"A 30-second timer is enough to fill the entire space with dust."

After finishing all this, Nishikawa Tetsu quickly put the fence back in place and then waved to the two of them.

"Get out of here! The farther the better! This is no joke!"

Without any hesitation, the three of them instantly turned into afterimages and retreated towards the distant building.

The rain seemed to be getting heavier along the evacuation route.

The three men crouched temporarily in the shadow of a towering water storage tank. This place, about four hundred meters away from the arsenal disguised as a sewage treatment plant, was a relatively safe observation point and a transit point for their retreat.

Nishikawa Tetsu leaned against the rusty stand and glanced down at the specially made watch.

"Twenty seconds left."

His voice was very soft, mostly drowned out by the sound of the rain.

In this suffocating countdown, the three people, who had been on edge the whole time, all relaxed their shoulders a little.

"call……"

Minato Namikaze wiped the grime from his face, a mixture of rainwater and sewer sludge, revealing his signature, yet somewhat weary, smile:

"I can't believe it, we actually did it, right under the nose of a demigod, we put poison down his throat."

He turned his head, his azure eyes gleaming in the darkness: "Che, your plan may sound crazy, but when it was executed... it was truly an art."

"It's science," Nishikawa Tetsu corrected, taking out three slightly damp candies from the innermost layer of his ninja tool bag.

These are cheap lemon candies, the kind the old lady sells at the entrance of Konoha Village, five ounces a bag.

"Let's replenish our sugar levels." Nishikawa Tetsu tore open a piece of sugar and popped it into his mouth. The sour taste invigorated him. "The next step is the escape mission, and the brain will become sluggish if it's lacking sugar."

He handed one to Minato, and then handed the last one to Fugaku Uchiha.

Fugaku, who was standing guard with his back to the two men, turned his head slightly when he heard the noise. He looked at the cheap candy and his brows furrowed as usual.

"I don't eat sweets," Fugaku said coldly. "Besides, we're on a mission right now, not..."

"Here you go, Captain."

Minato Namikaze had already crunched the candy into pieces, interrupting him with a muffled laugh: "Tetsu calculated it, this candy can provide about... uh, anyway, enough energy for you to run two more kilometers."

"It's 18 kilocalories, enough to keep the brain functioning at a high level for five minutes," Nishikawa Tetsu added, still holding his hand up. "Fugaku-senpai, this is also a tactical supply."

Fugaku Uchiha looked at the two young faces.

One is filled with rational composure, the other with emotional sunshine.

Over the past three months, he went from initially looking down on and disliking the country to eventually accepting it.

Although he never said it, in his heart, these two boys from common backgrounds were no longer "subordinates," but "comrades" to whom he could completely entrust his back.

"……cut."

Fugaku let out a very soft, arrogant snort, reached out and grabbed the candy, roughly tore open the wrapper and stuffed it into his mouth.

"It's so sour!" he commented, frowning. "Disgusting."

"You didn't spit it out even though it tasted awful," Nishikawa Tetsu quipped, a rare occurrence for him.

Minato couldn't help but chuckle softly.

In this frigid land of rain, in this dangerous enemy-occupied territory, this brief burst of laughter seemed all the more precious.

"Feed".

Fugaku suddenly spoke, his gaze still fixed on the distant armory, but his voice softened, carrying a hint of barely perceptible awkwardness:

"After we get back to the village..."

"Hmm?" Minato and Tetsu both looked at him at the same time.

"If... I mean if we can get an S-rank rating for this mission, and the bonus comes out..." Fugaku paused, seemingly doing a lot of mental preparation, "I'll treat you guys to barbecue. We'll go to that place in the Uchiha clan's territory this time; it'll definitely be better than what Jiraiya-sama makes."

Minato paused for a moment, then his eyes lit up: "Really?! Barbecue from the Uchiha clan's territory?! I heard it's really hard to get a reservation there!"

"I have special privileges." Fugaku raised his chin, his face still covered in mud, but the poise of a young master from a wealthy family was back. "Don't embarrass me later, behave yourself."

"It's a deal!" Minato raised his fist.

Fugaku looked at the fist, hesitated for a second, and then reached out and gently touched it with his own fist.

Finally, the two looked at Nishikawa Tetsu.

Nishikawa Tetsu looked at the two men's fists and felt a warm current surge in his heart.

Even knowing what will happen next, even knowing how cruel the future may be, at least at this moment, this bond is real.

"If someone's treating me, I'll definitely go."

Nishikawa Tetsu extended his fist and bumped it against the two of them.

"To get back alive for the sake of barbecue."

"Go back alive."

The moment the three fists collided.

"Time's up," Nishikawa Tetsu said softly.

……

Inside the underground armory.

Just as Nishikawa Tetsu had predicted, this was a vast underground space filled with countless boxes affixed with sealing talismans. The dry air made it a rare comfort zone in the Land of Rain.

Dozens of Rain Ninjas responsible for guarding the area were playing cards or resting.

"What does it taste like?"

One of the rain ninjas suddenly sniffed, "It smells pungent, like someone is stir-frying chili peppers?"

"Cough cough! My eyes are burning!"

Before they could react, a plume of pale red smoke billowed out from the ventilation ducts, quickly filling the entire hall.

"Poison gas! Enemy attack! Cough cough cough!"

Screams erupted instantly. The high concentration of irritating gas caused everyone to cough violently, tears streaming down their faces, their vision blurring, and some even scratching their throats in agony, unable to concentrate their chakra.

"Quick! Turn on the exhaust fan! Run it in reverse!"

The leader of the Rain Ninja team roared despite the excruciating pain.

However, just as he was trying to pull the alarm...

The silvery-gray dust particles in the air, barely visible to the naked eye, have reached a critical concentration.

Inside the ventilation duct, the timed detonator had deactivated.

"Beep".

A tiny spark lit up at the pipe opening.

For a confined space filled with combustible dust, this is the Grim Reaper's scythe.

"BOOM!!!"

First came a muffled growl, as if something deep underground had exploded.

Immediately afterwards, the sturdy concrete building seemed to inflate like a balloon, its walls cracking instantly and all the windows shattering.

Then, a pillar of orange-red fire shot into the sky!

The massive explosion ripped off the roof of the "sewage treatment plant," sending countless concrete fragments and twisted steel bars flying hundreds of meters into the air.

The terrifying shockwave, accompanied by intense heat, swept across all buildings within a radius of four hundred meters.

Even the three members of the fifth squad who had already evacuated to a safe distance were forced to lower their bodies as the air currents made their clothes flutter.

"this……"

Minato Namikaze turned back to look at the enormous mushroom cloud that bloomed in the rainy night, the firelight reflected in his azure pupils, his face filled with shock.

Its destructive power was comparable to that of a Tailed Beast Ball.

"Is this... a scientific ninja tool?"

As Fugaku Uchiha gazed at the towering flames, his throat grew dry.

He originally thought Nishikawa Tetsuya just wanted to cause some trouble, but he didn't expect that this kid would directly destroy someone else's base.

Under such high temperatures and a series of explosions, let alone detonating tags and ration pills, even chakra metal would probably have melted.

"Art is an explosion."

Nishikawa Tetsu lay on the roof, calmly recording the range and power of the explosion.

"The heat release is as expected, and the dust dispersion rate is also very high. It seems that Amegakure's ventilation system is very efficient and has been a great help."

However, just as the three were preparing to take advantage of the chaos to escape.

"Aaaaaah!!"

Suddenly, several piercing screams echoed from the burning ruins.

Several Rain Ninjas, their bodies engulfed in flames and their eyes blinded by smoke, emerged from the sea of ​​fire like headless flies.

They writhed in the mud in agony, trying to extinguish the flames on their bodies, but the flames, mixed with thermite, could not be put out by the rain.

"That's..." Minato Namikaze turned his head away, somewhat reluctantly.

"That's the enemy."

Fugaku Uchiha coldly interrupted him, but a deep sense of apprehension crept into his gaze as he looked at Tetsu Nishikawa.

This seemingly harmless and unassuming young man, once he gets going, is so ruthless and efficient that it's utterly appalling.

If this kind of person isn't a teammate, they're a nightmare.

"Stop looking, mission accomplished."

Nishikawa Tetsu put away the notebook, his expression unchanged.

"With such a commotion, Hanzo must have been alerted. If we don't want to be hunted down by demigods, we need to get out of the core area immediately."

"Walk!"

Fugaku Uchiha made a decisive decision.

Taking advantage of the chaos of the crowd and the cover of the firelight, the three quickly made their way to the outskirts of Amegakure.

However, what they didn't know was...

On the highest spire in Amegakure.

A muscular man wearing a gas mask and shirtless stood atop the tower, coldly gazing down at the towering flames.

Rain fell on him, running down his hideous scars.

Sansho fish, half-cooked.

"The rats of Konoha...?"

Hanzo's voice was hoarse and deep, coming through the mask with a suffocating sense of oppression.

He slowly raised the scythe in his hand and pointed it in the direction of the eruption of fire.

"Order the entire village to be sealed off. Find those rats... for me."
