Uchiha Kei, the Miner

Uchiha Kei, trapped in the Dark Space, had no idea what was happening in the Shinobi World, nor did he know that his students were searching for him throughout the entire Shinobi World.

All Uchiha Kei knew was that his Prototype Seed had grown to the size of a watermelon!

Watching the Prototype Seed frantically crush the black matter, Uchiha Kei felt speechless.

When it was only the size of a soybean, it was still acceptable for it to be inside the body.

Just think of it as multiple fat deposits in your body.

Now that the watermelon is the size of a watermelon, what should we do with it?

Is it a tumor?

In the beginning, the Prototype Seed consumed the black matter and needed him to provide a huge amount of Chakra.

Now, there's absolutely no need for Uchiha Kei's help anymore; the Prototype Seed is happily crushing the black matter on its own.

As large chunks of black substance fell, Uchiha Kei was completely numb.

Things are valued for their rarity.

When something is very rare, you feel it is incredibly precious when you see it.

But when this stuff is packed into sacks and sacks, even the most precious things don't seem so precious anymore.

Right now, there are about a dozen sacks at Uchiha Kei's feet, each filled with relatively large chunks of black substance.

The largest of them even allowed him to use Prototype Seed to carve out the outline of a Ninja Blade.

Of course, it's impossible to sharpen a blade; even Prototype Seed doesn't have that kind of delicate work.

What he's holding now is Ninja Blade made from black material.

It feels heavy and substantial in hand.

"Buzz!"

The moment the Prototype Seed broke through a block of black matter, a large swarm of the previous small insects emerged from it.

Uchiha Kei remained completely unfazed.

The small insect from before almost cost him his life.

But now he's as steady as a rock!

Sure enough, the moment the little insect appeared, the Prototype Seed rushed towards it with inexplicable joy, like a dog seeing a bone.

"Snap!"

The Prototype Seed crashed into a swarm of tiny insects, instantly shattering their bodies.

Wisps of black mist drifted out from their corpses and disappeared directly into the Prototype Seed.

Uchiha Kei raised an eyebrow as he looked at the Prototype Seed.

When it was the size of a soybean, he could see every little bit the Prototype Seed grew.

It's now the size of a watermelon, and despite all the black mist from so many insects, it hasn't grown any bigger.

If there is anything to say, it is that the Prototype Seed has become more cohesive, and the golden light it emits has become increasingly bright.

Uchiha Kei sat cross-legged on the ground, no longer observing the Prototype Seed.

Ten days have passed since we entered the black space.

Uchiha Kei roughly estimated that they had already dug a distance of nearly twenty-five meters.

What was initially thought to be an impossible task was almost completed in ten days.

As the excavation drew closer, Uchiha Kei gradually came to understand the purpose of this mission.

He still doesn't understand what the black substance is.

However, the Prototype Seed is growing rapidly as it is constantly crushed and absorbs small insects.

The power of the Prototype Seed was evident in its battle against the Big Thunder.

The Prototype Seed at that time was just a tiny bud, yet it possessed such power.

What if it were now?

Wouldn't that mean chasing after the Big Thunder hammer?

Thinking of this, Uchiha Kei couldn't help but smile.

He felt that he was now capable of striking two Big Thunder.

Just as he was secretly pleased, suddenly, the Prototype Seed stopped moving.

Uchiha Kei was of one mind with it, and his eyes instantly sharpened.

He could feel a strong sense of crisis instantly welling up in his heart as he faced the unexplored black substance ahead.

Front...

Something terrifying is coming!

The Prototype Seed stopped consuming the black matter and swayed in the void, occasionally turning to look at Uchiha Kei, seemingly waiting for him to make a decision.

Uchiha Kei frowned.

The danger that could be sensed through the black substance was definitely not something that the small insects from before could compare to.

But what else can we do if we don't dig?

Are you waiting for the mission to fail?

The loss of two Intermediate Ninjutsu was a blow he could not bear.

Especially now that Ōtsutsuki Isshiki could cause trouble at any time, the loss of two Intermediate Ninjutsu is a significant blow to his strength.

"Continue!"

After a long period of contemplation, a resolute Uchiha Kei's eyes as he gritted his teeth and stared ahead.

Upon receiving the command, the Prototype Seed plunged headlong into the black substance and continued its frantic digging.

One meter.

Two meters.

Three meters.

Four meters.

When we got to the last meter, that sense of crisis became clearer than ever before.

Uchiha Kei gripped the Ninja Blade made of black substance tightly in his hand, his gaze deep and unfathomable.

"Snap."

Through the tireless efforts of the Prototype Seed, the last meter...

They've made it through!

The moment the hole was dug, the Prototype Seed flew back to Uchiha Kei at incredible speed, leaving a trail of afterimages.

Seeing the Prototype Seed hiding behind him, Uchiha Kei rolled his Byakugan.

Although the details of the Prototype Seed are unknown, it has been given the title of god; surely it shouldn't be so timid?

That's so damn embarrassing...
