Chapter 81: Chapter 81: The Sage's Authority
Land of Hot Water, Underground Secret Base.
The place had undergone significant expansion since the last time.
Thirty large medical breeding tanks were lined up, the first of which contained the corpse of Shinosuke Hyuga. As the only captured member of the main family, Yuto couldn't bear to "juice" him. Besides, he didn't need another Chunin corpse, so he kept it as a specimen.
In addition to the breeding tanks, many expensive instruments had been added. Yuto had been stationed on this battlefield for a year. Even without significant kills, he had hunted many shinobi with kekkei genkai, often scavenging their bodies.
With more raw materials, Yuto's experiments increased. Thanks to the bombardment of information from his previous life, he had many peculiar ideas. Although most were impractical, a few were valuable. To avoid delaying his research, he acquired many instruments and chemical supplies, even securing restricted drugs from the battlefield medical team.
"Perverted serial killer, mad scientist, bastard rogue shinobi…" Yuto often described himself this way to the slug.
Now, he was about to add another title: "Ethics Challenger."
Chewing on jerky to regain strength, Yuto knew that the next task couldn't be taken lightly, despite his current extreme excitement.
Yuto began to understand why Orochimaru was so obsessed with human experiments—unveiling the secrets of kekkei genkai and ninjutsu bit by bit brought an indescribable sense of satisfaction and anticipation. In some ways, it was even more exhilarating than gaining power.
Curiosity and ambition are vital for societal progress.
After another hour, Yuto felt he had reached his optimal physical and mental state. He bit his fingertip and summoned a slug.
Bang! The smoke cleared, and the summoned creature's head hit the base's ceiling, its soft body pushing Yuto against the wall. Instruments and glass bottles clattered onto the table.
"Ah... Yuto-kun," the slug said pitifully, "I'm too big."
"No problem. Why don't you go back and summon a smaller part of yourself?"
"I can't. The Slug Sage put something in me that prevents me from shrinking."
"You can use the Transformation Jutsu!"
"I don't know how..."
Yuto was taken aback, recalling that the toad, Gamabunta, also couldn't use the Transformation Jutsu and had borrowed Naruto's chakra to transform into a fox to fight Shukaku.
"Katsuyu-sama, I'll infuse the chakra for the Transformation Jutsu into you. Think of the human form you want to take."
"Okay, Yuto-kun."
Bang! The transformation was instantaneous.
A petite girl appeared in the underground base, wearing a blue and white kimono, with long blonde hair tied into twin tails.
Yuto facepalmed. "Katsuyu-sama, why did you transform into this form?"
"Because you like blondes, Yuto-kun."
"?" Yuto touched his nose. "Well, I do admire Minato-Senpai. You noticed, huh? Hahaha..."
Oblivious to Yuto's awkward laugh, the slug nodded. "I also noticed you seem to like soft, plump..."
"Stop! Let's get to business, Katsuyu-sama." Yuto covered her mouth.
As expected, the split slug's mind and power were far less mature than the original. It spoke without considering the situation, Yuto thought.
He gently patted his face, composed himself, and took out several black short rods. Two fingers thick and palm-length, they seemed unremarkable. However, any sensory-type shinobi would notice that these rods had an incredibly high chakra conductivity, capable of transmitting chakra over great distances.
In a few years, Nagato would be very familiar with these.
These were the chakra Black Receivers used to control the Six Paths of Pain! Not only Nagato but also Tobi, Madara, and Kaguya Ōtsutsuki had used them.
Anyone with the "Otsutsuki Eyes" could create chakra Black Receivers using yin-yang release. These rods required minimal effort and weren't tied to eye techniques.
In the original series, Tobi controlled the tailed beasts with just one Rinnegan, creating Black Receivers effortlessly.
One Rinnegan and the Half-Awaken Tenseigan in mask mode weren't much different in essence.
Last month, after conceiving this shocking plan, Yuto refined it multiple times. He then sought help from the slug sage in Shikkotsu Forest, completing all the details.
He painfully used a "God's Mask," briefly regaining the Half-Awaken Tenseigan, and created these Black Receivers.
As he expected, he could infuse chakra into the rods even outside the mask mode.
His spiritual essence remained unchanged, and the deepest imprint in his body couldn't be erased. The Black Receivers still recognized him as their master.
"Slug-sama, shall we begin?"
"Yes." The slug, in the form of a blonde girl, opened her mouth wide, releasing a torrent.
This torrent had no physical form. It entered the Black Receivers without leaking, likely due to the slug sage's pre-applied sage techniques for precise infusion.
The invisible torrent was the slug sage's immense life force.
This sage, who had lived for over a thousand years, was trapped underground in Shikkotsu Forest but was truly immortal. As long as the ninja world existed, the slug sage would continue to live.
A fragment of this eternal life force was now being infused into the small slug, then transferred into the Black Receivers.
After an unknown period, the blonde girl suddenly said, "Yuto-kun, it's almost done... Five seconds left."
Understanding, Yuto immediately put on a "God's Mask."
His bloodline was restored, the power of the Ōtsutsuki clan returned to his body, the Caged Bird Seal vanished, and the light blue "Half-Awakened Tenseigan" reappeared.
Yuto squinted slightly. With his current ocular power, he could easily see that the slug had kept her promise. The life force infused into the Black Receivers was pure, without any mental imprint.
He had no conflict of interest with the slug. Allies like this were invaluable.
Yuto sighed in relief.
He clasped his hands together, reaching peak mental focus.
Bang! A large medical breeding tank exploded. The preserved item in the chemical solution was pulled by gravity towards the Black Receivers.
It was a beautifully curved rib, harder than steel!
As the life force infusion finished, the blonde girl vanished in a puff of white smoke.
Yuto lowered his hands, merging all his mental and ocular power into a powerful needle.
This needle connected the Black Receivers and the rib.
He was about to create life, defying nature and morality.
This was the authority of a Sage!
