The All-Purpose Chakra

Through experimentation, Kamiya Keiyun discovered that channeling chakra into the meridians enhanced not only strength but many other attributes—defense, reaction speed, and so on.

Taken together, it could all be summed up as: Cell Strength!

Shinobi certainly didn't wear steel-toed boots; on the contrary, they usually wore sandals, with their toes exposed.

What if, while running, they stubbed a toe on a rock?

But after infusing chakra, whether it was muscle or fat being strengthened, the end result was that Kamiya Keiyun could tap his leg lightly with a wooden stick and feel no pain.

Of course, if he hit harder, he still felt it.

Further testing revealed that this boost was also tied to the amount of chakra input.

The more chakra infused, the greater the increase in strength.

However, each individual meridian could only hold a limited amount of chakra, which led Kamiya Keiyun to discover the value of the Bright Virtue Method.

By using the Bright Virtue Method to improve Chakra Control, chakra could flow through normally impassable, tiny meridians.

These tiny meridians were like the small blood vessels at the ends of capillaries, only able to accommodate the most minuscule amounts of chakra. If a person lacked sufficient Chakra Control, they couldn't utilize these meridians at all.

"Everyone's body is the same, the number of meridians is the same, and chakra's enhancement to the body is the same. So, under identical conditions, how can one become stronger than others?" Kamiya Keiyun pondered. Having come from an era of cutthroat competition, he didn't even need to think to know the answer.

First: Chakra Control.

With his current perception, Kamiya Keiyun had no idea how many capillary meridians existed inside his body. He could only deepen his Chakra Control. Obviously, everyone was in the same boat—whoever had better Chakra Control could utilize more capillary meridians, and thus gain a greater boost to their body.

If Chakra Control reached a sufficient level, perhaps even an untrained, soft, pale hand could strike with the force of a cannonball.

Second: Body Strength.

Since it was an enhancement to the body, the stronger the original body, the stronger the enhanced body would naturally be. Would Tang Keke and Saitama get the same result from the same chakra boost?

Third: Meridian Strength.

Since more chakra meant a greater boost to the body, what if some people had wide meridians while others had narrow ones? Those with wide meridians would naturally be stronger than those with narrow ones. Even if the narrow-meridian person's Chakra Control reached grandmaster or Super Gene level, if they still had less chakra stored in a single meridian than someone else, what use was it?

Fourth: Chakra Quality.

If the first three conditions were all equal, then the final comparison came down to this: Chakra Quality.

In Wuxia novels, there was the concept of impure internal energy. The internal energy cultivated from a divine technique was far superior to that from a trashy one. A genius who trained in a divine technique could, fresh out of the gate, defeat a veteran martial artist who had trained for Decades.

While cultivating the Bright Virtue Method, Kamiya Keiyun also discovered that chakra could be compressed. Originally, he had a clump of chakra the size of an egg, but now he had squeezed it down, shrinking it significantly.

With mass unchanged and volume reduced, density naturally increased. Chakra trained this way would naturally be of higher quality.

If possible, Kamiya Keiyun even wanted to try Chakra Liquefaction and Chakra Core Formation.

Back in the classroom, the teacher was lecturing while he continued experimenting below.

Could chakra only strengthen the legs?

Not at all—it could strengthen the entire body.

Flowing into the body, it increased physical strength and defense.

Flowing into the hands, they became harder and stronger.

Placed at the heart, it made the heartbeat more powerful and blood circulate faster.

Placed in the lungs, it made breathing stronger and gas exchange more efficient.

Placed in the stomach—oh, the meridians there were so damn thin, he couldn't even penetrate them.

But Kamiya Keiyun felt that if he could manage it, it should improve digestion efficiency.

If he then strengthened the small and large intestines...

Maybe a whole pig could be digested in just a few minutes!

The human body had even more organs: liver, spleen, kidneys, lymph nodes, blood vessels, nerves, bones, eyes, ears, mouth, nose, tongue, and most critically—the brain.

If chakra were used to strengthen the brain, wouldn't he be in a constant state of brain overclocking?

"It's practically omnipotent—this chakra is terrifyingly powerful, isn't it? As I recall, the concept of chakra in my past life came from Indian yoga. By cultivating it, one could open the three main channels and seven chakras, ultimately reaching the realm of Oneness of Brahman and Self and Transcendence of Subject and Object. This world's chakra is a bit inferior, but it still has that potential. So..."

The first thing that came to Kamiya Keiyun's mind was: Could there really be such immortals in this world?

And then came a great confusion.

If chakra could strengthen the human body to that extent, then what was the deal with giant robots fighting Aliens?

With chakra this strong, they still couldn't beat aliens?

"Wait, I'm an idiot. I've been fooled by the Avengers and Hollywood blockbusters." Kamiya Keiyun shook his head. In Hollywood movies, aliens travel thousands of miles just to engage in hand-to-hand combat with humans.

In that case, chakra would naturally be sufficient.

But in reality, aliens were more like how they were depicted in The Three-Body Problem—they came from far away and then, from an even greater distance, simply blew up your planet. What could you do?

So, you still had to pilot a giant robot to wage interstellar war.

"To fight aliens, an ordinary mech won't cut it. It has to be one that can reach dozens or even hundreds of times the speed of sound, with acceleration exceeding dozens of Gs. Facing alien cannons and lasers, it also needs super-fast reaction speed and sensitivity. If an ordinary person piloted such a mech, they'd die during the acceleration phase alone. So, it has to be someone who has cultivated chakra and strengthened their body to pilot it!"

In his free time, he had also chatted with his groupmates and roommates about the interstellar age. A common view was that if humanity wanted to enter the interstellar age, they had to evolve first.

Otherwise, forget about whether they could pilot a spaceship—just the vast knowledge of the interstellar age alone would take an ordinary person Decades to learn. How could they carry on the legacy?

You definitely need a brain capable of overclocking!

And that lines up perfectly with Chakra!

"So if you want to become a Gundam pilot, you first have to master Chakra. A Gundam that can fight Aliens—you can't build more than a handful even pooling an entire planet's power. When the time comes, they'll pick the most outstanding candidates to be pilots."

"I didn't travel across worlds just to wave a flag and be background noise. I'm going to be one of them!"

Kamiya Keiyun clenched his fist, ready to push harder, when the bell rang.

Another day of study was over!

I really do think Chakra can amplify everything—including sight, hearing, and smell.

The Inuzuka Clan can amplify their sense of smell, making their noses tens of thousands of times sharper than a human's.

Jonin move so fast—Rock Lee's movements are invisible to genin, but jonin can see them clearly. That should be because jonin use Chakra to amplify their vision, giving them dynamic eyesight.

The most typical example is Kakashi. When he uses Lightning Cutter, he needs the Sharingan to aim. But Lightning Cutter is still slower than Flying Thunder God, and Namikaze Minato doesn't need the Sharingan to calibrate his position.

That suggests Minato was born with naturally strong dynamic vision and reaction speed—strong enough to surpass even the Sharingan.

But this kind of amplification is either innate or relies on secret techniques. Not everyone can learn it. For example, the sense of smell is something only the Inuzuka Clan has mastered.

And amplifying the fingers to achieve an effect similar to Finger Gun? That's a secret technique of the Cloud Shinobi.
