This ninja in Naruto is unscientific

Chapter 186 Perception Barrier

In the eastern part of the Grass Country, deep in a hidden canyon.

The night was as dark as ink, and the campfire was deliberately kept low. The Third Raikage, A, sat cross-legged on a huge rock, devouring a massive beast leg.

"Snap!"

He bit the meat and bones into pieces and swallowed them whole.

"Lord Raikage, a reply has arrived from Iwagakure."

A Cloud Village intelligence ninja appeared like a ghost and handed over a scroll.

The Third Raikage casually wiped the grease from his mouth, took the scroll, and ripped it open.

By the dim light of the fire, he quickly scanned the contents of the document and then let out a suppressed but excited chuckle.

"Hmph, that old bastard Onoki finally agreed."

Raikage crumpled the scroll into a ball, and with a flash of lightning in his palm, instantly turned it into ashes.

"At noon tomorrow, launch the general offensive. They will be responsible for containing Konoha's main force from the front, while we will be responsible for a flanking attack, heading straight for the command post."

"Sir, are the people from Iwagakure... trustworthy?" Tsuchida asked with some concern. "That Onoki is notorious for being two-faced."

Whether it's believable or not is not important.

The Third Raikage stood up, his bones cracking, his steel-like muscles radiating a suffocating sense of oppression in the night.

"The important thing is that the current situation forces them to cooperate with us, unless they want to face Konoha's counterattack alone."

"and……"

Raikage clenched his fist, his knuckles turning white.

"Once the fighting starts tomorrow and the situation becomes chaotic, it will be too late for them to back out, even if they want to. In the face of absolute power, any conspiracy or trickery is a joke."

"Pass down the order: the entire army shall rest and recuperate."

……

Meanwhile, at the Konoha front-line camp.

Nishikawa Tetsu was sitting in the corner of the command post, holding a cup of hot tea, but he didn't drink it. He just kept rubbing his right eyelid.

"What's wrong, Che?"

Minato Namikaze had just returned from inspecting the camp when he saw this scene and couldn't help but ask with concern, "Are your eyes bothered?"

"It's not that I'm feeling unwell."

Nishikawa Tetsu sighed, put down his hand that had been rubbing his eyes, and looked distressed.

"It keeps twitching. There's an old saying that a twitching left eyelid means good fortune, while a twitching right eyelid means bad luck. My right eyelid has been twitching like crazy since after dinner, and it's making me anxious."

"superstitious."

Kakashi happened to be passing by and overheard this. He rolled his deadpan eyes and retorted without hesitation, "As the vice president of the Science Research Institute, to believe such a scientifically unfounded claim is utterly shameful."

"What do you know? This is a sixth sense, a living being's instinctive warning of danger!"

Nishikawa Tetsu glared at Kakashi with annoyance, then stood up and paced back and forth in the tent.

The plan is perfect.

Iwagakure has already betrayed us, Kumogakure is about to fall into their trap, and Fugaku is on his way with reinforcements.

Logically speaking, this should have been a sure-win encirclement and annihilation battle.

But the unease in Nishikawa Tetsu's heart just wouldn't go away.

"Could it be...that thing?"

If there is any uncontrollable variable in this war, it is only that old schemer who has lived for thousands of years.

"No, I have to go to the barrier class."

Nishikawa Tetsu suddenly stopped in his tracks, grabbed his coat, and walked out.

"Huh? It's so late?" Minato was taken aback.

"If you can't sleep, go and add a lock to our security door."

……

At the edge of the camp, the tents of the Perception Barrier Class.

It was already late at night, and several sensory ninjas responsible for maintaining the barrier were taking turns dozing off. When they saw Nishikawa Tetsu enter, they hurriedly tried to get up.

The title of "Konoha's Grim Reaper" earned Nishikawa Tetsu a considerable amount of respect within the military.

"Sit down, sit down, don't be nervous."

Nishikawa Tetsu waved his hand, signaling everyone to continue working, and then walked straight to the central crystal ball—the Perception Water Ball.

"What does the current barrier primarily detect?" Nishikawa Tetsu asked.

"It mainly targets chakra fluctuations."

The leader of the barrier team, a Jonin from the Yamanaka clan, pointed to the water sphere and explained, "As long as hostile chakra enters a five-kilometer radius, the water sphere will change color. Even if someone uses invisibility jutsu, as long as there is chakra flowing within their body, they won't escape our detection."

"What if..."

Nishikawa Tetsu narrowed his eyes, took out a black metal box from his pocket, and asked as he opened it:

"What if the opponent could perfectly assimilate their aura into the earth and vegetation, to the point that even their chakra fluctuations are barely perceptible?"

"This..." The class monitor was stunned. "There shouldn't be such a ninja, right? Unless it's made of stone."

"some."

Nishikawa Tetsu thought of White Zetsu's Mayfly Technique, a divine infiltration technique that allows one to become one with nature.

"Therefore, we need to upgrade the system."

He attached the black box to the base of the sensing water sphere.

"What is this?" The class monitor looked curiously at the box that was flashing red light.

"Bio-electromagnetic wave amplifier".

Nishikawa Tetsu began adjusting the knobs, uttering a string of technical terms that left the ninjas present completely bewildered.

"Chakra can be hidden, but the bioelectric signals of living organisms cannot be completely eliminated. As long as something is alive, its heartbeat, muscle contraction, and nerve conduction will generate a weak electromagnetic field."

"I adjusted the frequency of this amplifier to the band targeted for underground foreign objects."

Nishikawa Tetsu's fingers flew across the keyboard.

"From now on, this barrier will not only be able to sense chakra, but also scan all changes in material density and bioelectrical reactions within a ten-meter radius underground."

"Even if it's an earthworm burrowing underground, as long as it's big enough, I can pull it out."

As Nishikawa Tetsu pressed the final confirmation button.

"Buzz—"

The water sphere suddenly emitted a low hum, and a faint, ethereal blue halo appeared on the originally clear water surface.

"alright."

Nishikawa Tetsu clapped his hands, looking at the machine that was working properly, and felt a little relieved.

"Squad leader, thank you for your hard work tonight. Keep an eye on this new monitor."

He pointed to the small radar screen on the black box.

"If you spot an unidentified object moving rapidly underground, regardless of whether there is a chakra reaction, immediately sound the alarm."

"Yes! Understood!"

Although I don't understand the principle, since it was explained by Nishikawa Tetsu, it must be very important.

After doing all this, Nishikawa Tetsu stepped out of the tent.

A night breeze blew by, bringing a chill to the air.

He looked up at the moon, which was obscured by dark clouds, and his right eyelid seemed to have finally stopped twitching.

"Whether it's Black Zetsu or White Zetsu, as long as you dare to stick your claws in..."

Nishikawa Tetsu touched the electromagnetic pistol at his waist, his eyes cold.

In the woods not far away, Obito was secretly carrying a bunch of wildflowers, preparing to place them at the entrance of Rin's tent under the cover of night.

"Hehe, Lin will be so surprised when she sees this tomorrow morning, right?"

Obito grinned foolishly, completely unaware that behind the tranquil night, a massive net was quietly being cast.

But deeper underground.

A white figure darted through the rocks like a fish, stealthily making its way towards the Leaf Village camp.

"Hmm? What does that feel like?"

Bai Jue suddenly stopped. He felt as if an invisible ripple was scanning the earth ahead.

"Konoha's sensory barrier has become stronger? It can even cover the depths of the earth?"

Bai Jue hesitated for a moment, a hint of caution appearing on his comical face.

"Forget it, let's take a longer route. If we get caught, Lord Madara's plan will be ruined."
