Chapter 124 - UK:GSW Chapter 124: Uchiha Setsuna's Mangekyō Sharingan Ability 

Uchiha Setsuna took a deep breath and gazed at Uchiha Kei with intense eyes. "Kei-kun, are there many of these?"

Uchiha Kei replied, "It was an accidental byproduct from researching genjutsu-based games. It's linked to a special summoning technique only I can use. No one else can summon it. As for the quantity, it's fine to let a few people eat and drink freely."

He was right—no issue at all. These days, Uchiha Kei did ten 10-pulls daily. After all, if the shinobi world had anything in abundance, it was emotional energy. Even without golden spirits, he had to run at least ten 10-pulls a day to keep the emotional values from piling up into worthless overflow.

And from those ten 10-pulls, he usually got a mountain of junk food bundles. Occasionally, when he did get a golden spirit, the rest would still be a flood of items and happy gamer meals.

By now, Uchiha Kei's system inventory had thousands of these so-called happy gamer meals stacked up.

So yes, saying there's enough for a few people to binge wasn't a problem. Besides, they couldn't eat too much anyway, because...

"Such incredible satiety... Kei-kun, these aren't just delicious—they have powerful effects and serve as excellent military rations. My appetite's not small, far beyond average, yet just a can of that thing called 'cola' and one 'burger' left me full. I can even feel the stored energy is enough to refine a huge amount of chakra."

"If we had this kind of food during the Great Ninja War, just one serving could probably sustain a shinobi's chakra output for an entire day."

Uchiha Setsuna carefully recalled and analyzed how he felt after consuming it. He couldn't help but exhale deeply, clearly impressed.

Uchiha Kei only smiled in response. He had already tested the effect with Minato Namikaze and the others—he knew exactly how it worked.

What could he say? Anything the system produced was high-quality. Originally, the system gave him these items to help overworked employees stay efficient. It was basically a "corporate slave meal." But in the shinobi world, with its lack of nutritional support and high energy consumption, this stuff had become top-tier super rations.

If he deployed his current stash of happy gamer meals in the Great Ninja War, it could increase their battlefield efficiency by 300%.

After all, great logistics can drastically shift frontline strength. Just imagine—if the volunteer army in the previous world had even a fifth of the enemy's logistical support, they might've driven the enemy into the ocean. Even the world's dominant naval power would've kept its distance.

If Uchiha Kei used these meals to support Konoha's forces, it could truly lead to something insane like: "Three thousand fight ten thousand, we hold the advantage, the enemy doesn't surrender and dares to counterattack, and within three days we force the invaders into a desperate capital defense."

After Kei gave the nod, Uchiha Setsuna shared his impressions of the cola and burger with the others and added something crucial:

"I can feel my depleted life force and energy recovering. I was sure I wouldn't last beyond next month... but now, I think I might live several more months."

"If I keep consuming Kei-kun's food, I might not have to worry about dying anytime soon."

Everyone present was shocked. All the senior Uchiha members showed disbelief, quickly replaced by excitement.

Elder Setsuna might not die after all!

For the Uchiha clan, this was tremendous news.

It wasn't that they didn't trust Uchiha Kei—it was that the Mangekyō Sharingan, once taken from its original owner, couldn't exert full power. For someone like Kei, not a direct blood relative, using Setsuna's Mangekyō would only grant partial access to its abilities, plus a huge physical burden and risk of blindness.

If possible, it was best for Setsuna himself to use it—and that was exactly the point Kei was making. It was why he gave him the food.

Of course, system food wasn't some miracle elixir—it couldn't truly extend life or cure illness. Its main benefit was energy replenishment. And what Setsuna lacked was energy and vitality, lost from using the Mangekyō Sharingan.

There was no way to recover that loss in the current Uchiha clan. All they could do was watch him slowly fade away.

Under those circumstances, Uchiha Fugaku humbly asked Kei for some of the same food for his own father—Uchiha Masanobu—and revealed that Masanobu planned to awaken his Mangekyō Sharingan, even if it meant dying.

Kei didn't know what to say. Yet another one aiming to awaken the Mangekyō? If he'd known there were so many, he wouldn't have gone to such lengths to get Obito to open his eyes!

He was full of snarky complaints.

Soon after, Kei handed Masanobu a burger and a cola, then spoke earnestly:

"Everyone, I hope in the future, if someone in the clan awakens the Mangekyō, you won't keep it from me. This information is extremely important for me—it directly impacts my strategic planning for our clan's future."

Everyone quickly agreed. No more secrets. And they meant it—before, the secrecy came from Uchiha Setsuna's pride and misplaced sentimentality. But now that they realized no sacrifices were needed and Kei's system food had real effects, no one wanted to keep him in the dark anymore.

Uchiha Masanobu then tried the food himself. As with Setsuna, his energy and vitality recovered—though to a lesser extent.

That was expected. Masanobu's current weakness stemmed from injuries in the Second Great Ninja War. Though he survived, he'd lost much of his strength and accumulated internal injuries. His condition was very different from Setsuna's, who was drained from Mangekyō usage.

Some disappointment lingered, but Masanobu smiled.

"No, this is already wonderful. There's no need to be upset. I was ready to die after awakening my Mangekyō. But now, thanks to Kei-kun's miraculous food, I might live another year or two even after awakening. That's a huge gain for me. What's there to be sad about?"

"My friends, look ahead. What Kei-kun has brought to the Uchiha clan is our true future. And the things he holds in his hands can ensure our clan's prosperity for the next hundred years."

"We now stand on a bright road forward. And with Kei-kun leading us, our clan's dream is sure to be realized!"

His heartfelt words lifted everyone's spirits. As he said, they'd already braced for the worst. Now, Kei had turned the situation around. What was there to dwell on?

More importantly, they still had to deal with Black Zetsu hiding in the shadows. Just the thought of a thousand-year-old monster stalking them was enough to cause insomnia.

The conversation turned serious again. Uchiha Setsuna's Mangekyō Sharingan was added to the strategy roster—but after learning what his dōjutsu could do, everyone was a little... underwhelmed.

Setsuna's Mangekyō had awakened from his epiphany after witnessing Kei's brilliance and realizing the folly of his own life.

His left eye could dispel all illusions—disguises, smokescreens, visual interference, and all genjutsu were rendered ineffective. It reflected his former delusions and desire to never be deceived again. He named it "Kishin."

His right eye was a protective shield, born from his will to guard the Uchiha clan and Uchiha Kei, the clan's beacon of hope. It could create a barrier that protected anyone within. Simple and direct, he named it "Bishamonten."

Both names were classically Uchiha—taken from Japanese mythology, simple yet forceful.

He also had Susano'o, of course. But the cost of using it was too great. Even with Kei's super rations, using Susano'o might still kill him. Unless it was absolutely necessary, Setsuna wouldn't use it.

Uchiha Kei then used his ability to replicate other Sharingan abilities and copied Setsuna's Mangekyō techniques, gaining two powerful new tools.

But while useful, Setsuna's Mangekyō powers weren't effective against Black Zetsu.

Honestly, using these techniques on Black Zetsu would be about as effective as doing tricks for an ancient monster.

They needed a different plan. The Mangekyō techniques wouldn't help here.

After further discussion, they decided Uchiha Masanobu would go ahead with awakening his Mangekyō Sharingan, while the rest prepared in secret to deal with Black Zetsu.

As for Kei—he planned to meet with his close friend Minato Namikaze, and try to get him and Kushina Uzumaki involved too. Hopefully, they could rally more support.

With an old snake like Black Zetsu, you had to use every available resource to take it down in one go. Never give it a chance to fight back.

And so, after finalizing their plans, Uchiha Kei left the clan compound.

Only then was the barrier that had blocked information released—allowing Black Zetsu, lurking underground, to hear what had happened.

But by then, the Uchiha had already rehearsed the perfect act. They loudly discussed the clan's plans and Masanobu awakening the Mangekyō—all things Black Zetsu already knew. So there was no reason to hide them.
