"Kai, you seem to be biting off more than you can chew. Learning an A-rank jutsu is no easy feat. Even the experienced Uzuki took over a month to learn it. How could you possibly succeed in just three days?" Inuzuka Haka couldn't help but say.
"Alright, young people are like that. They learn from their mistakes," Uzuki Ao patted Inuzuka Haka's shoulder, "Hopefully, Kai will understand that some things can't be forced."
(Note: Made up a name for Kiba's dad.)
Outside the cave, in a slightly secluded basin.
Kai spread out the Lightning Release scroll and immediately activated his Mangekyō Sharingan.
The Sharingan in Kakashi's hands made him famous as the Copy Ninja Kakashi.
For a ninja, learning jutsu had two crucial stages.
First was mastering the basics, and second was achieving mastery.
However, Kai now had the Mangekyō Sharingan, allowing him to instantly master the basics. As for mastery, he could achieve it with one click.
Kai was now equipped with both the physical cheat code and the invincible level-up cheat from the original story.
He was freaking OP!
"Ding, detected hand seal speed. Do you want to max level it?"
"Max level it now."
Kai's hands moved quickly, and his chakra underwent precise nature transformations.
"Lightning Release: Thunderclap!"
The moment the last hand seal was formed, a low rumble echoed through the sky.
Nine bolts of lightning, like dragons emerging from the depths, struck a rock about eight meters away with a fierce force.
Boom!
The massive rock shattered.
Sparks flew, and debris scattered, creating a crater about ten meters wide.
The smoke and dust made the scene even more chilling.
Seeing this, Kai was stunned.
According to the scroll, once you mastered the A-rank Lightning Release: Thunderclap, you could connect with the stray lightning elements in the world and unleash a thunderclap attack.
However, what he saw went beyond that.
"Could it be because of the one-click to max level system?" Kai raised an eyebrow.
He remembered that in the original story, Uchiha Madara had once said, "There is no weakest jutsu, only the weakest people."
Even a Fire Release: Great Fireball Jutsu could be used like a powerful move.
Only Uchiha Madara could do that.
Now, Kai's situation was probably due to the jutsu max level system.
However, the attack just now had consumed one-tenth of his chakra.
"Ding, Lightning Release chakra, one-click to max level."
"Ding, Lightning Release: Thunderclap, one-click to max level."
"Ding, Lightning Release: Natural Energy Sensing, one-click to max level."
The system prompts in his mind instantly confirmed Kai's thoughts.
Looking at the huge crater created by the thunderclap, he suddenly remembered a powerful lightning jutsu from Uchiha Sasuke.
S-rank Lightning Release: Kirin!
It could be said that if this jutsu didn't require specific timing, location, and conditions to use, it could have easily rivaled Naruto's Wind Release: Rasengan.
Unfortunately, in the original story, this Lightning Release: Kirin made a powerful entrance but was ultimately short-lived.
It only appeared three times!
This was a regret for many Naruto fans.
The Cloud ninjas attacking now numbered over a hundred, and they also had the AB duo. This was bound to be a tough battle.
If they got into a protracted war, with Kai's current chakra level, even with the Mangekyō Sharingan, he would be drained to death.
Therefore, this S-rank Lightning Release: Kirin might be the key to turning the tide for Kai.
It could harness the power of natural lightning, significantly reducing chakra consumption, achieving a speed of one-thousandth of the speed of light. As a large-scale attack, it could achieve a surprise effect.
Besides, Kai had the one-click to max level system.
There was a high chance that he could replicate the Lightning Release: Kirin, temporarily using it as his trump card.
......
Three days passed in a blink of an eye.
"Ding, Lightning Release: Kirin, one-click to max level."
Hearing the familiar prompt, Kai breathed a sigh of relief.
The connection he had established with the thunderclouds in the sky was instantly severed.
The thunderclouds in the sky dissipated, and a vast pressure, like a fleeting bloom, vanished.
"Thankfully, I have the one-click to max level system. Even my Lightning Release: Natural Energy Sensing is maxed out. Otherwise, I wouldn't have been able to successfully test the Lightning Release: Kirin so smoothly," Kai dispelled his chakra.
His training in recent days had made him realize the Uchiha clan's weakness: chakra consumption.
No wonder the Byakugan and the Sage Body were always drained in protracted battles.
Even Uchiha Madara in the original story had to transplant and absorb the First Hokage's cells.
It seemed that after this was over, Kai would have to find a way to get his hands on the Sage Body.
When Kai emerged from the secluded basin, the 27 Konoha ninjas left behind had already assembled.
Each of their faces was solemn, and they were all prepared for battle, their eyes filled with a sense of determination to die.
In their eyes, this unavoidable war, facing over a hundred Cloud ninjas, including the AB duo, was a lost cause.
However, behind the stronghold was the vast Land of Fire.
If they lost this stronghold, not only would Konohagakure be in danger, but their families would also be in jeopardy. Therefore, they couldn't retreat.
"Kai, don't be discouraged if you haven't mastered the A-rank jutsu. Even Uzuki, that old fart, took over a month," Inuzuka Haka couldn't help but say.
"But the sudden appearance of those storm clouds just now, it felt like something was hiding in the clouds, putting pressure on our minds. We thought the Cloud ninjas were trying to ambush us."
"Haka, why bring that up? Can't you say something else for once?" Uzuki Ao glared.
"Kid, don't put too much pressure on yourself. Just like I said before, if you can't handle it, you and Shizune should escape first. You can't learn a jutsu in just two or three days."
Seeing Kai appear, many of their expressions relaxed slightly.
After witnessing Kai's powerful genjutsu firsthand, they had a newfound sense of trust in this once-unremarkable young man.
