Seeing Might Guy once again full of fervor, shouting as he ran off on his hands, Might Duy's face turned serious as he looked at Mirai Uchiha.
"Mirai, your talent is immense, so I've decided to teach you the secret technique of the 'Eight Inner Gates.'
After saying this, and before Mirai Uchiha could respond, he continued on his own:
"Although I'm just a mere genin now, the Eight Inner Gates are a very powerful secret technique.
"Mirai, I'll show you right now.
Might Duy feared that Mirai Uchiha would look down on the Eight Inner Gates because of his low rank, so he decided to demonstrate it to him in person.
"Mirai, watch closely.
"First Gate: Gate of Opening, open!
With Might Duy's muffled shout, Mirai Uchiha could feel the chakra within his body starting to circulate frantically.
Might Duy's skin also turned much more flushed.
"Second Gate: Gate of Healing, open!
"Third Gate: Gate of Life, open!
After opening the third gate, Might Duy's body became congested and red, and a green aura began to radiate from his body.
"Fourth Gate: Gate of Pain, open!
"Fifth Gate: Gate of Limit, open!
"Sixth Gate: Gate of View, open!
After opening the sixth gate, the veins on Might Duy's skin bulged, and his entire body looked like a cooked shrimp.
But the violent aura emanating from him left Mirai Uchiha stunned.
He felt that what stood before him was not a person, but a beast.
A beast that could devour anyone at any moment!
Just as Mirai Uchiha was carefully analyzing the changes in Might Duy, the latter clenched his fists and shouted again.
"Seventh Gate: Gate of Wonder, open!
A torrent of chakra several times stronger than before suddenly erupted, and the green aura covering his body transformed into a blue vapor.
Mirai Uchiha couldn't help but step back a few paces, and only after creating some distance did he feel a bit safer.
Worthy of the Eight Inner Gates—this power… it's terrifying, Mirai Uchiha thought in awe.
Might Duy's chakra was at the level of an ordinary genin, far below his own.
But now, his chakra had reached an extremely terrifying level.
And, compared to his chakra, Might Duy's body was even more fearsome.
Mirai Uchiha couldn't help but activate his Sharingan, but even then, his vision blurred for an instant, and Might Duy was already standing right in front of him.
He couldn't even catch his movements.
"Huff… huff… huff…
"Mirai, these are the Eight Inner Gates.
Might Duy panted, speaking with difficulty:
"Even I, after opening the Eighth Gate, would gain power ten times greater than that of the Five Kage.
"However, since opening the Gate of Death means certain death, I can't demonstrate it to you now.
When Might Duy finished speaking, the blue vapor around his body gradually dissipated, and he collapsed to the ground.
"Mirai, although opening the Eight Inner Gates can grant a massive boost in power for a short time, it also places a tremendous burden on the body.
"You must always remember that.
Hearing Might Duy's warning, Mirai Uchiha nodded silently.
When reading the manga, the power of the Eight Inner Gates had already left him in awe.
Now that he had seen it with his own eyes, Mirai Uchiha only felt a burning excitement inside.
This secret technique that boosts one's power so brutally… it's simply insane.
Might Duy gave Mirai Uchiha a few more pointers on using the Eight Inner Gates and then began teaching him the method.
The way to train the Eight Inner Gates was actually quite simple; as long as one's physical condition was strong enough, there wasn't much difficulty.
Thus…
In just one afternoon, Mirai Uchiha was already able to open up to the fifth gate.
Such speed left Might Duy dumbfounded once again.
Where did this monster come from?!
…
Deep in the night.
Uchiha Clan Compound.
Mirai Uchiha ate the last piece of roasted meat, a satisfied smile on his face.
Although his current body only allowed him to open up to the fifth gate, that was already enough to use it as a trump card.
Moreover, he had the plundering system to gain attribute points.
Opening the final gates was only a matter of time.
And most importantly…
Might Duy had taught him the Eight Inner Gates on his own initiative.
That meant he could use them freely in battle without worrying about raising others' suspicions.
…
Time flew by.
A month passed in the blink of an eye.
During this month, Mirai Uchiha didn't go on any missions.
First, because he needed time to get used to his rapidly growing power, and second, because the bandits had quieted down a lot during this period, and there really weren't any suitable missions.
But even so, the basic rewards gained through daily battles had greatly increased his strength.
The greatest gain was his eyes.
Now, he had already evolved his Sharingan into one with three tomoe.
"Panel!
With Mirai Uchiha's soft call, a sky-blue, semi-transparent panel appeared before his eyes.
[Name: Mirai Uchiha]
[Constitution: 117]
[Mental Strength: 102]
[Chakra: 68]
[Kekkei Genkai: Sharingan]
[Ninjutsu: ...]
[Others: ...]
Seeing the numbers on the panel, a faint smile formed on Mirai Uchiha's lips.
When his Mental Strength attribute reached one hundred points, his Sharingan successfully evolved from two tomoe to three tomoe.
Unlike other members of the Uchiha clan, Mirai Uchiha didn't need any traumatic stimulus; his eyes evolved as naturally as eating or drinking. Everything happened naturally.
This also made him realize that, as long as his Mental Strength was strong enough, his eyes could evolve into the Mangekyō Sharingan in the same way they had evolved into the three-tomoe Sharingan.
Just thinking about the powerful and mysterious dōjutsu of the Mangekyō Sharingan made him feel a little excited.
What Naruto fan wouldn't be fascinated by the Mangekyō Sharingan?
…
The next day.
Early in the morning.
Mirai Uchiha, as usual, left the clan compound, planning to find a place to have breakfast and then continue his training.
However, the noisy discussions in the street made him frown slightly.
"Have you heard? It seems the Third Kazekage of the Sand Village has gone missing!
"Really? But he's a Kage, a warrior as strong as Lord Hokage. How could someone like that disappear?
"Of course it's true, the news has already spread. They say the Cloud Village even tried to take advantage and attack the Sand Village, but they were repelled.
"Seriously! Looks like the ninja world is about to fall into chaos again.
"…
While eating breakfast and listening to the people's discussions, Mirai Uchiha understood what was happening.
The Third Kazekage has disappeared. The Third Great Ninja War is about to begin!
