From the night of genocide, marching towards the strongest.

"What is this stone? How can it contain such a large amount of chakra energy?"

He could tell at a glance that the chakra armor and the white lines were made of chakra metal.

But this stone?

Intrigued by the strange stone, Sasuke fell into deep thought.

He could sense that this blue stone, no bigger than a fist, possessed a chakra level no less than that of a Jonin.

In other words, as the saying goes, 1 calorie!

Sasuke was quite surprised that a single stone could possess such a large amount of chakra.

Even chakra crystals don't come in such large quantities; they're just of extremely high quality.

Where did this thing come from?

Sasuke pondered all his memories of the original story, but nothing matched the stone.

It's something from a chapter I haven't read before!

Or rather, what other messy plot holes has Mr. Bo buried behind the scenes!

If I had known this in my past life, I would have read all the chapters. Even if Boruto drops to a 2-point rating, I would still have gritted my teeth and finished it.

After failing to find any clues, Sasuke mentally complained.

"The blue patterns on this armor are modeled after the meridians in the human body, and the stone is located in the dantian, the source of chakra."

"It is the combination of the two that can amplify the effect of the wearer's ninjutsu."

Although he didn't understand the origin of the stone, Sasuke quickly figured out the principle behind the Chakra Armor Amplification Ninjutsu.

"So how do you use it? Swallow it? Or place it near your navel?"

Sasuke muttered to himself, then took the stone off and put it into his storage scroll.

How could he possibly use something of unknown origin so rashly, let alone eat it?

He has figured out the principle behind the chakra armor amplification ninjutsu, and he can try to apply it to his own lightning armor in the future.

As for the stone that served as the source of chakra, he also found a better alternative.

That's the Futsu-no-Mitama Sword!

As he pondered silently, Sasuke once again donned his dazzling lightning armor.

"The next step is to incorporate meridians and dantian, mimicking the circulation of chakra in the human body."

The Futsu-no-Mitama sword in his hand transformed into a bolt of lightning and merged into the armor, making the electric light on the armor even more dazzling and brilliant. The chaotic lightning began to coalesce into thick electric snakes.

"That's a bit difficult."

Sasuke narrowed his eyes. The human body is incredibly complex, and Lightning Release chakra is the most difficult chakra to control. To imitate the human body with Lightning Release is no easy task.

The black pupils in his eyes gradually turned scarlet, forming an eerie six-pointed star shape, and the uncontrollable lightning seemed to have encountered its sovereign.

At the command, in no time at all, the electric wires in mid-air intertwined and coiled together like vines.

Each component forms the nerves, veins, blood vessels, and even muscles and textures of the human body, suddenly converging into the image of a humanoid suit of armor.

News of the Chunin Exams (Chapter 120)

"A useless thing!"

After observing for a while, Sasuke concluded.

What's the difference between this and a smaller version of Susanoo?

The only difference is that it consumes significantly less energy.

Sasuke shook his head. In his mind, the Lightning Armor was a low-cost ninjutsu that could be used in normal conditions.

If that's the case, it would be better to use Susanoo.

However, it wasn't a complete loss; they did make some progress with Susanoo, the Thunder God.

The human body is too intricate to be imitated under normal circumstances. Just like the chakra armor, it is enough to simply imitate a few main meridians and the dantian.

This lightning armor is much stronger defensively than before.

After pondering for a moment, Sasuke calmed down, walked to the side, picked up a ninjutsu scroll, looked at it for a while, and then casually put it into his pouch.

This ninjutsu, called Lightning Release: Binding Technique, was obtained by him from the Third Hokage.

Naruto and Sakura took the Vacuum Giant Ball and the Hard Vortex Water Blade, respectively.

To be honest, Sasuke has no shortage of either Fire Release or Lightning Release. In fact, it could be said that the strongest Fire Release and Lightning Release techniques in Konoha are passed down in his hands.

As for the Flying Thunder God Technique, Impure World Reincarnation, and other techniques he truly wanted to learn, it's likely that the Third Hokage wouldn't grant them to him.

So when the Third Hokage asked him what ninjutsu he wanted to learn, he casually mentioned a ninjutsu that could trap the enemy.

He already has offensive ninjutsu, and defensive ninjutsu is under development, but he doesn't have a single ninjutsu to bind enemies.

Lightning Release: Binding Technique is a rare binding ninjutsu among Lightning Release techniques. When used in conjunction with colleagues or shadow clones, it can be used to perform advanced versions of the Four Pillars Binding Technique and the Sixteen Pillars Binding Technique.

Of course, if you have the ability, you can do it alone.

For example, Sasuke has only been learning for a few days, and he can already use the Four Pillars Binding Technique on his own. The ultimate version, the Sixteen Pillars Binding Technique, is just a matter of time.

In the original timeline, the Sixteen Pillars of Restraint once trapped a portion of Pain for a period of time.

This ninjutsu is better than nothing for Sasuke.

After putting the scroll into his pouch, Sasuke bit his thumb and released the summoning jutsu.

With a bang, a ninja cat with pointed ears and messy, raccoon-like fur appeared in the spot.

"Young Master Sasuke, is there something you need?"

As soon as Tian Huo appeared, he greeted them.

"Okay!" Sasuke handed over the catnip drink and the scroll containing the mysterious stone, saying, "Could you please help Granny Cat find out the origin of this thing, and also gather information about the Snow Country's Fuuka Nutō during his years of travel in the ninja world?"

After Fuka Naoto's older brother, Fuka Naoyuki, inherited the title of Daimyo of the Land of Snow, Fuka Naoto left the Land of Snow and disappeared for several years.

It was during that period that he gathered wandering ninjas such as Wolf Fang Avalanche, and eventually returned to the Land of Snow to kill his brother and usurp the throne.

That stone must have been obtained during the years he disappeared.

All of Sasuke's subsequent plans would be inseparable from chakra, and naturally, the more of this important substance, the better.

After giving the instructions and seeing Tahiko off, Sasuke tidied up the training ground and headed towards the underground laboratory in his home.

He continued his research on Yamato cells and Heroic Water.

.................

Meanwhile, on the main street of Konoha.

Naruto, who was unexpectedly beaten up by Sakura after a chance encounter on the street, also encountered an unexpected guest who came to Konoha during his escape.

A loud bang.

At a corner, Naruto bumped into a strange boy who was walking around the corner. The boy's face was covered in purple paint and he was carrying a backpack wrapped in bandages.

"It hurts!"

Kankuro was knocked back a few steps. He felt as if he had bumped into a piece of hard steel, not a person.

Rubbing his slightly dizzy and flushed forehead, Kankuro looked at the newcomer and said in an extremely displeased tone:

"You yellowish-brown-haired guy, are all the ninjas of Konoha this reckless?"

As he spoke, Kankuro reached out and tried to grab Naruto's collar.

Upon hearing this, Naruto, who was about to apologize with a smile, froze. After realizing what was happening, his face instantly filled with displeasure, and he grabbed Kankuro's outstretched hand.

"You guy with your face covered in scribbles, are you blind? This is clearly the golden light of a bright little sun!"

'That was fast! I didn't even have time to react!'

Kankuro was secretly alarmed to see Naruto grab his right hand before he could react.

He silently increased the strength in his hand, trying to break free from Naruto's grasp, but even with all his might, Naruto's hand remained as firm as a steel clamp, holding his right hand so tightly that he couldn't move it at all.

Taijutsu ninja?

Sensing the immense power emanating from every joint of Naruto's hand—it seemed that even the strength of a single finger was greater than that of his entire arm—Kankuro's expression subtly changed.

"So, you're actually a taijutsu ninja known for your strength."

Kankuro glared fiercely at Naruto, his left hand secretly reaching for the puppet behind him.

"Looks like I'll have to teach you a lesson..."

"Kankuro, what are you trying to do?! Are you going to use that? Stop it!"

A tall, blonde girl walked up and said in a deep voice.

"Naruto, let go."

"Humph!"

Naruto gave a soft snort and released Kankuro's right hand.

Sakura walked over, glanced at the two of them, and said, "You're from Sunagakure, aren't you? Although Konoha and Sunagakure are friendly allies, provoking Konoha ninjas in Konoha is not a benevolent act."

"It was clearly you guys from Konoha who bumped into me first, humph!"

Kankuro rubbed his slightly numb right hand and looked at the girl, cursing as he spoke.

"Hehe, I'm sorry about that, Naruto didn't mean it."

Sakura narrowed her eyes slightly and chuckled lightly, trying to smooth things over: "Naruto bumped into you, and you cursed at him. Let's just let this matter go."

Upon hearing this, Kankuro glanced at Sakura and saw that the girl had a fawning smile on her face (in her own opinion), fair and smooth skin, and a particularly unremarkable figure.

He was clearly just an ordinary, even rather weak, ninja.

“This is between me and this guy, it’s none of your business. If you dare to meddle, I’ll beat you up first.”

Kankuro said fiercely, releasing a slight aura and killing intent, the threat of which was self-evident.

"hehe...."
