Chapter 11 Ways to Increase Chakra

In the mornings of the Land of Rain, the air is so humid it feels like you could wring water out of it.

After last night's not-so-secret special training session, the atmosphere in Class 5 eased a bit.

Although Fugaku Uchiha still had a stern face, the look in his eyes when he looked at Toru Nishikawa was less of a burden.

Today's lesson is divided into two parts.

Fugaku Uchiha stood on the muddy ground, arms crossed, his eyes blazing: "Practical taijutsu, and... especially training to increase a person's chakra reserves."

Nishikawa Tetsu raised his hand with self-awareness: "Senior, you can just give me your ID number."

Fugaku Uchiha ignored his complaints and immediately assumed the starting stance.

"Let's start with taijutsu. On this battlefield, you won't always have the chance to create distance and unleash ninjutsu."

"Once the enemy gets close, close combat skills will be your last line of defense."

He looked at Minato Namikaze: "Minato, you go first. Attack as fast as you can."

"yes!"

Minato Namikaze's eyes narrowed, and he instantly transformed into a golden afterimage.

"Whoosh!"

Almost in the blink of an eye, Minato Namikaze's whip kick swept towards Fugaku Uchiha's neck.

This strike was swift, accurate, and ruthless, accompanied by a whistling sound as it cut through the air; it was far beyond the power a newly graduated genin could muster.

However, Fugaku Uchiha did not even awaken the Sharingan.

He merely tilted his head slightly and shifted his body back with an extremely small movement, and the whip kick grazed the tip of his nose.

Immediately afterwards, Fugaku Uchiha flipped his wrist and precisely grabbed Minato Namikaze's ankle.

"Too straightforward."

Fugaku Uchiha made a cold comment and then used the momentum to throw the object away.

Minato Namikaze was thrown into the air, but he reacted quickly, performing a beautiful backflip in mid-air and landing steadily.

"Your speed is impressive; that's truly your talent." Fugaku Uchiha looked at Minato Namikaze with a serious tone.

"But your actions were too obvious, and your intentions were revealed too early. In the face of a true Sharingan, every step you took was within my expectations."

"You need to learn feints and speed changes, instead of just blindly pursuing speed."

Minato Namikaze nodded thoughtfully, a thoughtful glint in his azure eyes: "Change speed, break the rhythm?"

It feels great to teach geniuses; they grasp things instantly.

"That's right."

"Next, Nishikawa Toru."

Fugaku Uchiha turned his head, his eyes looking like a big bad wolf looking at a little lamb.

Nishikawa Tetsu sighed and assumed the basic taijutsu stance taught at the ninja academy.

He knew that the next few minutes would most likely be a one-sided beating.

as predicted.

Five minutes later.

"Bang!"

Nishikawa Toru was once again slammed into the mud by Uchiha Fugaku's over-the-shoulder throw.

"Too weak."

Uchiha Fugaku looked down at the panting Nishikawa Tetsu: "Insufficient strength, even slower speed. If I were the enemy just now, you would already be dead."

Nishikawa Tetsu struggled to get up and wiped the mud off his face.

Although his body was protesting, his brain was working at high speed.

"Strength and speed are hardware differences that cannot be overcome in the short term," Nishikawa Tetsu said, panting.

"But I've noticed that your muscle activation habit always prioritizes protecting your left ribs. Is that muscle memory left over from a previous injury?"

Fugaku Uchiha paused for a moment, then subconsciously touched his left rib.

That was the spot where I was injured by a Sand Ninja puppeteer half a year ago. Although it has healed, the subconscious defensive action is still there.

"Good observation skills."

A hint of surprise flashed in Fugaku Uchiha's eyes. Although this kid's eyes weren't Sharingan, his insight was sharp.

He pulled two wooden kunai from his waist and tossed them to the two men: "Martial arts are not just about fists and feet, but also about weapons."

For the next hour, Fugaku Uchiha began to teach various ruthless killing techniques, which was definitely not a one-sided beating!

……

Break time.

The three sat under the tree, with Nishikawa Tetsu drinking water in large gulps.

He always felt that he was being targeted by Fugaku Uchiha, because Minato's face was completely unharmed while he himself was bruised and swollen.

"Next, the main event."

Fugaku Uchiha looked at Toru Nishikawa with an extremely serious expression.

"Nishikawa Tetsu, your tactical mind is indeed excellent, but your chakra reserves are your fatal weakness."

"While the theory of the Great Fireball Technique last night was ingenious, it was based on having a certain amount of chakra."

"What do I need to do?" Nishikawa Tetsu put down the kettle and asked earnestly.

In this world, the amount of chakra almost determines the upper limit of a ninja.

"Chakra is the combination of physical energy and spiritual energy."

Fugaku Uchiha held up two fingers. "The dumbest yet most effective way to increase the total is to break through the limit."

"Exploiting the body and the mind."

He pointed to a huge rock not far away: "Exhaust your last bit of strength, and then, in that state of extreme fatigue, when your brain is even unable to think, forcibly refine your chakra to allow your body to adapt."

"It's painful and dangerous. While this method can increase chakra, everyone's constitution is different, and their physical limits vary."

"Uchiha Fugaku said in a deep voice."

"Furthermore, if it's not controlled properly, it can damage your body, so I'll be watching you with my Sharingan."

"I see."

Nishikawa Tetsu quickly transformed this theory into a scientific model in his mind.

Body energy = ATP production efficiency of cellular mitochondria.

Mental energy = focus and willpower of the nervous system.

The "Extreme Breakthrough Method" involves depleting glycogen through high-intensity anaerobic exercise, forcing the body to enter an emergency compensatory mechanism, and simultaneously compelling the nervous system to maintain high-frequency discharge under high pressure.

Simply put, it's about treating the body like a battery, eliminating the memory effect and forcibly increasing the battery capacity through repeated deep charging and discharging.

"Understood."

Nishikawa Tetsu stood up, his eyes resolute.

He knew he didn't have the physique of the Uzumaki clan, nor did he have the power-up of a tailed beast.

To survive to the end in this world full of overpowered characters, besides having a brain, you also need a resilient body.

"Let's begin then."

The next two hours became Nishikawa Tetsu's hell.

Push-ups, weighted runs, tree climbing until chakra is exhausted and you fall.

Whenever Nishikawa Tetsu felt he had reached his limit and couldn't even move a finger, Uchiha Fugaku's cold voice would ring in his ears.

"Start refining your chakra now, don't let your body rest!"

The feeling was like trying to squeeze water out of a dry sponge; every meridian was in pain.

Minato Namikaze was also sparring alongside him, but he was clearly much more at ease.

His physique was already superior to that of ordinary people, so this level of training was more like a warm-up for him.

But Minato Namikaze didn't seem relaxed at all; instead, he kept encouraging Tetsu Nishikawa from the sidelines: "Tetsu! Hang in there! Breathe, adjust your breathing rhythm!"

at last.

As Nishikawa Tetsuya rose from the ground countless times, trembling as he formed the "Un" seal, he felt a faint but warm surge of new chakra welling up from the depths of his parched dantian.

Although the amount was small, this chakra was purer than ever before.

"stop."

Fugaku Uchiha's voice was like heavenly music.

Nishikawa Tetsu collapsed onto the muddy ground, his chest heaving violently, sweat and rain mingling and blurring his vision.

"How are you feeling?" Fugaku Uchiha walked over and handed him a bottle of soldier rations.

"It feels...like dying once."

Nishikawa Tetsu swallowed the pill, feeling his strength slowly returning, but a tired smile tugged at the corner of his mouth: "However, I think I've figured it out."

He closed his eyes, feeling the subtle changes within his body.

If his chakra mixing ratio was previously arbitrary, it caused a lot of spiritual and physical energy to dissipate before combining.

So now, under extreme conditions, the body instinctively finds the most efficient point in order to protect itself.

It's not just about expanding capacity, it's also about purification.

"very good."

Fugaku Uchiha looked at the disheveled but still bright-eyed boy on the ground and nodded.

"At this rate, your chakra level should reach that of an average Chunin within a month."

For an ordinary person without a bloodline limit, this is already an astonishing rate of progress.

"Okay, take a ten-minute break."
