Elemental Chakra Mode

At the Uchiha Clan Head's home that afternoon, Shin went to Fugaku and got a stack of chakra paper, then took his leave and returned to his room.

When Fugaku saw him then, his eyes were slightly red, but Fugaku did not think much of it.

He thought his younger brother had shed tears because he was upset that he could not learn taijutsu.

He never imagined that Shin had been moved after overhearing the conversation between Fugaku and their father.

Chakra paper could detect the chakra attributes a ninja possessed.

Chakra was divided into five attributes: fire, wind, lightning, water, and earth. As long as chakra was infused into the paper, it would change according to the corresponding attribute.

Fire: the paper would ignite.

Wind: the paper would split down the middle.

Lightning: the paper would crumple.

Water: the paper would become wet.

Earth: the paper would crumble.

Once Shin tested his chakra attributes, he would be able to better match them to his ninjutsu studies and chakra nature transformations.

He drew a sheet of chakra paper from the stack and infused it with a small amount of chakra.

Very quickly, the paper changed: one section caught fire, one section split apart, one section became wrinkled, one section grew damp, and the final section crumbled away.

Shin was instantly stunned. Staring at the result on the paper, he took out another sheet of chakra paper and tested it again.

"Looks like my chakra has all five attributes. Other than certain secret techniques, there are plenty of ninjutsu I can learn..."

He was very satisfied with the result.

Although his physical condition was poor, the variety of his chakra natures meant that even without following the path of taijutsu, he could still become strong.

Sure enough, when heaven closed one door, it always left another open.

Ninjas with all five chakra attributes were all geniuses among geniuses.

As far as Shin knew, both the Third Hokage Hiruzen Sarutobi and Kakashi Hatake possessed all five chakra attributes.

Moreover, one was known as the Professor of Ninjutsu, while the other was called "Kakashi the Equalizer"—ahem... the Copy Ninja.

Therefore, with five innate chakra attributes, it was far easier for him than for ordinary people to carry out nature transformations.

(Though later on, everyone could cultivate other attributes... even the Seventh Hokage in Boruto learned Earth Release.)

Shin wanted to copy all sorts of ninjutsu one by one, just like Kakashi Hatake.

But he knew that with the amount of chakra he had at five years old, he could not learn any profound ninjutsu.

With the boosts from all kinds of cheats, even learning one forbidden technique a day would not be a problem for him.

The problem was that with this tiny amount of chakra, even successfully releasing one would be difficult.

Thinking of this, his earlier excitement faded, and he began to think rationally instead.

"With my current chakra reserves, rather than learning ordinary ninjutsu, it would be more practical to develop my own abilities..."

Shin's body possessed some of a phone's functions.

His enhanced thinking speed, powerful hearing, dynamic visual tracking, and powerful memory corresponded to a processor, speaker, camera, and storage.

He believed that many more components were waiting to be developed.

Chakra was physical energy extracted cell by cell from the human body's 130 trillion cells. Its nature was much like "electricity," so cells were like "batteries" capable of recharging themselves.

However, chakra's true origin was the fruit of the Ōtsutsuki God Tree.

In other words, the God Tree converted the planet's difficult-to-use natural energy into chakra, which had a much lower threshold for use.

If the Sage of Six Paths had not distributed chakra among the people back then, this world would probably have been developing heavy industry like the planet where Shin had lived in his previous life.

Shin came up with an idea regarding the essence of chakra.

Cells were self-charging batteries, and chakra pathways transmitted chakra like electrical wires. So what would happen if he actively charged the cells?

There was a famous saying from his previous life: practice was the sole criterion for testing truth.

He decided to experiment.

Using nature transformation, Shin turned his chakra into the fire attribute.

Then he slowly injected it into his right index finger.

The corresponding cells immediately felt a faint sting.

He instantly understood something.

Charging was like dripping a drop of water onto a stack of tissues.

If you wanted to wet only one sheet, you had to pick it up before dripping the water, or separate it with something.

Otherwise, every sheet of tissue would become soaked.

Batteries also had capacity limits, and every cell had a different capacity.

After chakra was injected, the cells would change. Without isolation, it would also damage nearby cell membranes.

In severe cases, the cells could even die permanently.

Therefore, he also needed to use mutually restraining chakra to isolate the area around it.

Ten minutes later, Shin had used one-tenth of his total chakra to complete the injection of fire-attribute chakra into his right index finger.

At the same time, he used water-attribute chakra to isolate the base of the finger.

Aside from wisps of heat drifting from his fingertip, it looked no different from usual.

Yet its temperature was already close to that of an ordinary flame.

If he had used the fire-attribute chakra injection on a ninjutsu, he would already have completed a traditional nature transformation.

But with his current total chakra reserves, he could not even sustain the release of a single nature-transformation ninjutsu.

He looked at the finger maintaining its high temperature while consuming very little chakra, pondered for a moment, then rose and walked to the desk.

He then flicked the fingertip where fire-attribute chakra was concentrated at the desk before him.

With a bang.

The fire-attribute chakra within his fingertip instantly erupted, blasting the desk into powder.

Even the fragments left behind from the desk were charred black by the intense heat.

"Is it really this powerful? One finger can reach this level... though it would be difficult for someone with only one attribute to use..."

For Shin, who was naturally born with five attributes, all of this was child's play.

Among chakra attributes: fire restrained wind, wind restrained lightning, lightning restrained earth, earth restrained water, and water restrained fire.

After someone with a single chakra attribute used this, the corresponding cells would probably be ruined as a result.

After spending an entire afternoon testing various chakra attributes, Shin finally reached a conclusion.

All five chakra attributes could charge cells, and each had different properties:

The fire attribute increased power. After charging, it emitted high temperatures, and using chakra caused explosions. Its side effect was cellular dehydration.

The wind attribute could make cells lighter and grant gliding ability. After using chakra, high-frequency wind blades formed across the body's surface. Its side effect was cellular swelling caused by high-speed vibrations.

The lightning attribute increased physical speed. After using chakra, electric arcs formed outside the body. Its side effect was disrupting the cells' electrolytes, leading to weakness, nausea, convulsions in the limbs, coma, and other symptoms.

The earth attribute could strengthen resistance to blows. After using chakra, incomparably hard rock formed over the surface. Its side effect was cellular hardening.

The water attribute could increase cellular capacity and multiply parts of the body's tissue. Its side effect was permanent multiplication, which could only return to normal after the cells slowly consumed the water themselves.

Besides that, switching between different chakra attributes incurred a loss of around five percent.

As the number of cells whose maximum capacity his brain stored increased, this figure would decrease in a straight line.

In the end, Shin named the state of cells after they had been infused with attribute chakra Elemental Chakra Mode.

In this mode, it could enhance various aspects of his physique and allow for primitive chakra release.

With his current chakra reserves, he could not yet fully enter Elemental Chakra Mode.

If he forced his way into it, he could probably only maintain it for about one second.

Moreover, all the cells in his body would suffer side effects.

Perhaps after awakening the Sharingan, he would be able to reduce chakra consumption more precisely.

Then Shin might be able to last longer, right?
