Naruto: Evolution

Under his conscious control, the fourth evolution of [Constitution] began immediately.

Bzzzz…

The process caused no pain or discomfort. On the contrary, it was like immersing himself in a hot bath, a comforting sensation that completely enveloped him.

But this transformation went beyond the superficial.

At the cellular level, his body was reconstructing itself, strengthening in a way that could not be explained with words.

As soon as the evolution was complete, Gen felt a chill run through his body. A surge of strange energy emerged from within him and quickly spread through every fiber of his being.

It was a unique sensation.

As if his entire body were submerged in revitalizing hot springs, being nourished and reinforced from the inside out.

The process did not last more than a minute, but the difference was undeniable.

When everything was over, he slowly opened his eyes and let out a sigh.

He could immediately feel the changes in his body, and for a moment, he couldn't help but show astonishment.

"Incredible…"

It wasn't the first time he had evolved his [Constitution], but this fourth enhancement completely eclipsed the previous ones.

The energy within him flowed without limits, like an inexhaustible torrent of power.

And the most impressive thing was that his vitality was so intense that it could almost materialize around him.

Boom

Unable to contain the energy coursing through his body, he threw a punch into the air.

The punch compressed the air with such intensity that it generated a visible shockwave and a muffled explosion that expanded several meters before dissipating.

It wasn't just a sensation of power. It was real, tangible power.

After the evolution of [Constitution], not only had his training efficiency improved, but his physical capacity had drastically increased instantly.

Raising his right fist, he observed it carefully.

He could feel it…

The strength contained in his body was completely different from before. If he compared his current state to before the evolution, his physical power had practically doubled.

But the most interesting thing was that this growth did not follow a linear pattern.

Every time [Constitution] evolved, the improvement was not a simple sum of strength and endurance but an exponential leap.

If before this evolution his endurance and strength were comparable to those of a Chūnin, now he could confidently state that he had surpassed that level and was approaching the standard of a Jōnin.

However, this was not limited solely to his brute strength.

The evolution of his [Constitution] represented a total transformation of the body, including endurance, recovery capacity, and bodily toughness.

His endurance could only be evaluated over time and training, but his recovery capacity and the toughness of his body were things he could verify immediately.

Quickly, he took a kunai from his tool pouch and, without hesitation, rolled up his left sleeve.

Holding the kunai firmly in his right hand, he applied moderate pressure and slid the sharp blade over his forearm.

Any Genin without special abilities would have suffered a deep cut with that level of force. But in his case…

Nothing.

The only thing left on his skin was a faint white mark, as if the kunai had barely grazed its surface.

His body had reached a level where a Genin, using all their strength, wouldn't even be able to wound him with a sharp weapon.

The fourth evolution of [Constitution] had not only strengthened his physique… it had surpassed his own expectations.

Before this evolution, after completing the previous three, his bodily resistance had already far exceeded that of a normal person. Common weapons could barely scratch him, but they were still no obstacle for more advanced ninja techniques.

Even though a Genin was the lowest rank in the ninja hierarchy, their physical strength was still far above that of an average civilian.

To test his resistance, he increased the force of the cut and slid the kunai over his arm again.

This time, he applied a level of force equivalent to that of a Chūnin.

Finally, the skin opened, and a thin line of blood emerged from the wound. However, the process was not easy.

It was like trying to cut thick leather with a sharp blade—possible, but with noticeable resistance.

"At this point, saying I have a 'body of steel' wouldn't be an exaggeration…"

But what surprised him the most wasn't the toughness of his skin, but what happened next.

To the naked eye, the wound began to close on its own, as if his flesh were naturally repairing itself.

Small sprouts of new tissue formed within the cut, healing the injury at an impressive speed.

Less than thirty seconds later, the wound had completely disappeared, leaving no scar or trace behind.

Gen exhaled deeply, and a radiant smile appeared on his face.

This evolution had exceeded all his expectations.

Calming the excitement boiling inside him, he focused on the vital energy coursing through his body.

It was so dense and powerful that it could almost be perceived as chakra, something he hadn't noticed in previous evolutions.

Suddenly, an idea crossed his mind.

Almost instinctively, he tried to retract his vital energy, as if he wanted to hide it within his body.

And to his surprise, it worked perfectly.

In an instant, the powerful green aura surrounding him completely dissipated, as if it had never been there.

"It actually worked…"

He had attempted it out of simple curiosity, but he hadn't expected his vital energy to be concealed so easily.

Satisfied with the result, he smiled confidently.

Now, after the fourth evolution of [Constitution], his body could no longer be compared to that of an average ninja.

If with the third evolution his endurance was comparable to that of a talented member of the Senju Clan, now his constitution was at the level of a "Wise Body."

But such drastic growth was not without risks.

Power always attracted attention. If he revealed too much too soon, he would undoubtedly draw the wrong kind of interest.

That's why being able to hide his presence was an invaluable advantage.

With his vital energy completely contained, he let himself fall back onto the sofa and opened his talent template to review his progress.

[Sharingan ★☆—5000]

[Constitution ★★—10000]

[Ninjutsu ★☆—5000]

[Taijutsu ★☆—5000]

[Genjutsu ★☆—5000]

[Evolution Points—4537]

"So the fifth evolution requires 10,000 evolution points…" Noticing the amount needed for the next evolution of [Constitution], he murmured to himself.

The second star, which had previously been empty, now shone with a solid glow. But the most striking thing was that the evolution cost had doubled, increasing from 5000 to 10,000 points.

Doing a quick calculation, if he earned 24 evolution points per day, reaching the next evolution would take approximately a year and two months.
