Seeing Might Guy once again getting fired up and yelling while doing handstands and sprinting off, Might Duy turned to Mirai Uchiha with a serious expression.
"You have great talent, Mirai, so I'm going to teach you the Secret Art 'Eight Gates'."
Without waiting for Mirai Uchiha's response, Might Duy continued, "Although I'm just an ordinary Genin at the moment, the Eight Gates is a very powerful Secret Art."
"I'll show it to you now, Mirai. Watch closely."
Fearing that Mirai might look down on the Eight Gates due to his strength, Might Duy decided to personally demonstrate it in front of him.
"Mirai, pay attention."
[Opening Gate – Open!]
As Might Duy let out a low shout, Mirai could feel the other person's chakra wildly surging within his body. Might Duy's skin also flushed redder.
[Healing Gate – Open!]
[Life Gate – Open!]
After opening the third gate, Might Duy's body turned bright red from congestion, and green energy began radiating from its surface.
[Harm Gate – Open!]
[Limit Gate – Open!]
[View Gate – Open!]
After opening the sixth gate, Might Duy's skin bulged with visible veins, and his entire body resembled a thoroughly cooked giant shrimp.
But the violent aura radiating from Might Duy alarmed Mirai Uchiha.
He felt as though what stood before him wasn't a person—but a beast.
A wild beast ready to devour anyone at any moment!
While Mirai was carefully observing Might Duy's transformation, the latter suddenly clenched his fist and roared.
[Wonder Gate – Open!]
Chakra many times stronger than before erupted outward. The green energy covering his body transformed into blue steam.
Mirai instinctively took several steps back, feeling slightly safer after creating some distance.
"No wonder it's called the Eight Gates… This power… it's absolutely terrifying."
Mirai couldn't help but murmur to himself.
Might Duy's chakra reserves were only at the level of an average Genin, far less than his own.
Yet now, the opponent's chakra had reached an unimaginably terrifying level.
And even more than the chakra itself, Might Duy's physical presence was terrifying.
Mirai instinctively activated his Sharingan, but still found himself momentarily dazzled—Might Duy had already appeared directly in front of him.
He couldn't even track the other's movements.
Panting heavily...
"This is the Eight Gates, Mirai—"
Might Duy was panting heavily, struggling to speak. "Even for me, once I open the eighth gate, I gain ten times the power of the Five Kage."
"However, since opening the death gate also means death, I can't demonstrate it to you right now."
After Might Duy finished speaking, the blue chakra mist around his body gradually dissipated, and he collapsed onto the ground.
"Mirai," he continued earnestly, "While the Eight Gates significantly boosts your strength temporarily, it also places tremendous strain on your body."
"Remember this well."
Upon hearing Might Duy's advice, Mirai Uchiha silently nodded.
Back in his past life, while reading manga, the sheer power of the Eight Gates had already astonished him.
Now having seen it with his own eyes, Mirai felt his heart burning with excitement.
Such an overwhelming Secret Art that dramatically enhances one's strength… was simply unfair.
After giving Mirai some more tips regarding how to use the Eight Gates, Might Duy began teaching him the oral instructions for it.
The method of cultivating the Eight Gates was actually very simple; as long as one's physical condition met the requirements, there wasn't much difficulty in training it.
So…
It only took Mirai just one afternoon to successfully open the fifth gate of the Eight Gates.
This speed left Might Duy dumbfounded again.
What kind of monster is this guy?!
...
Late at night.
Uchiha District.
Mirai Uchiha took his last bite of grilled meat, wearing a satisfied smile on his face.
Although currently his body could only activate up to the fifth gate of the Eight Gates, it was sufficient to serve as a surprise trump card.
Besides…
He still had the Plunder System to acquire enemy attribute points.
Opening the remaining gates of the Eight Gates was only a matter of time.
Most importantly…
The Eight Gates was something Might Duy had willingly taught him.
In other words, he could freely use it in battle without worrying about arousing suspicion from others.
...
Time flew—nearly a month had passed in the blink of an eye.
During this past month, Mirai Uchiha had chosen not to go out on missions.
Firstly, he needed time to get accustomed to his rapidly growing strength. Secondly, mountain bandits had been unusually quiet lately, leaving no suitable missions available.
Even so, the daily match-derived rewards had significantly increased his overall power.
Among these gains, the most significant was his eyes.
Right now, he had evolved his Sharingan into a triple-comma form.
[Interface!]
[Name: Mirai Uchiha]
[Physique: 117]
[Spiritual Power: 102]
[Chakra: 68]
[Kekkei Genkai: Sharingan]
[Ninjutsu: …]
[Other: …]
Looking at the numbers displayed on the interface, Mirai Uchiha smirked faintly.
When his spiritual power reached one hundred, his Sharingan successfully evolved from a two-tomoe pattern to a three-tomoe pattern.
Unlike other Uchiha clan members, Mirai had never experienced any traumatic events. His evolution to the three-tomoe Sharingan had been as effortless as breathing.
This also made Mirai realize that with sufficient spiritual power, his eyes might evolve further, just like how his Sharingan had advanced to the three-tomoe stage—possibly even evolving into the Mangekyo Sharingan.
At the thought of the powerful and mysterious Dojutsu abilities granted by the Mangekyo Sharingan, he couldn't help but feel excited.
Among Naruto fans, who wouldn't be excited about the Mangekyo Sharingan?
...
The next day.
Early morning light filtered through the streets.
As usual, Mirai Uchiha left the clan compound in search of a breakfast stall, determined to eat well before resuming his training.
However, the loud gossip along the street made him frown slightly.
"Did you hear? The Third Kazekage of Sunagakure has gone missing!"
"Seriously? He's one of the strongest leaders in the ninja world—like the Hokage himself! How could someone like that just vanish?"
"It's definitely true—the news's everywhere. I heard Kumo tried to exploit the chaos and launched a surprise attack on Sunagakure, but they were pushed back."
"Wow! Looks like the ninja world's about to get chaotic again."
...
While having breakfast and listening to people's discussions, Mirai gradually figured out what had happened.
The Third Kazekage went missing—this meant the Third Great Ninja War was about to begin!
