Chapter 161: The Fourth Kekkei Genkai!
🕑 Added 2025-08-30 15:32:08 +0000 UTCChapter 161: The Fourth Kekkei Genkai!
Nara Keisuke lay under the shade of the tree, completely immersed in the brief moment of leisure. After an unknown amount of time, a stream of memories from a Shadow Doppelganger flowed into his mind.
"The A-rank technique I just acquired, 'Genjutsu: Sharingan,' has been successfully modified!"
The activation of "Genjutsu: Sharingan" only required the Sharingan's ability to perceive and manipulate spiritual energy. In other areas, such as enhancing dynamic vision or its potential for future upgrades, the Lacquer Eye was far inferior. But when it came to sheer insight and control over spiritual energy, Keisuke had the utmost confidence in the A-rank technique he had developed himself. Combined with the vast amount of research on the brain's neural pathways he had received from the Yamanaka clan, it was only natural that he could so quickly modify an A-rank genjutsu and make it his own.
Keisuke reviewed the training memories sent by his doppelganger and successfully mastered the modified technique. The system panel displayed a notification at almost the exact same time.
[A-Rank Technique: Genjutsu: Lacquer Eye]
"Hm, no need to change the name..."
Keisuke readily accepted the name of the new technique. "Since my clone has already produced research results, I suppose I can't keep lazing around."
He got up from the shade and scanned the two "experiment materials" on the field, his gaze finally locking onto the Five-Tails Jinchuriki, Han. Instead of using the genjutsu he had just developed, Keisuke opted for a different technique.
Shadow Manipulation Technique!
An incredibly fine shadow thread shot out from Keisuke's own shadow, darting across the grass and connecting to Han's. It completely sealed away the consciousness of the already-unconscious Jinchuriki. Keisuke took over his mind and, within that spiritual world, softly called out a name.
"Kokuō."
The almost pure-white Five-Tails, Kokuō, materialized its chakra and spoke calmly. "We meet again, Nara Keisuke."
"Long time no see, Kokuō," Keisuke greeted with a smile. "My original plan was to secretly abduct you without anyone knowing, but alas, fate had other plans. The war changed too quickly, and Han has become a prisoner of Konoha."
"I am aware," Kokuō said, bending its hind legs and folding its forelegs, lying down within the spiritual plane. The five great horns on its head drooped slightly. The sight made Keisuke's eyes sparkle.
Kokuō, and you say you're not a great white deer!
"Ninja have always feared the power of us Tailed Beasts, and their treatment of Jinchuriki is atrocious," Kokuō said, its sea-blue eyes fixed on Keisuke. "What does your village plan to do with Han?"
"Don't worry. After I argued my case, I've temporarily secured the authority to handle Han," Keisuke boasted, something he rarely did. "Without my permission, no one can take you from me!"
Kokuō nodded slightly. For now, it decided to trust the ninja named Nara Keisuke.
"As for a way to free you from Han's body, I'm still searching, but I already have a promising lead," Keisuke added, further placating the Tailed Beast. "Because I don't know the specific sealing jutsu Iwagakure used on you, I have to find another way... If Plan A doesn't work out, I have a backup. Kokuō, have you ever heard of the Uzumaki clan?"
"I have," Kokuō said placidly. "They are one of the descendants of the Sage of Six Paths. He passed his sealing abilities down to their bloodline."
That's Kokuō for you... even a casual chat can lead back to the Sage of Six Paths.
"Since you know of the Uzumaki, I won't have to explain much," Keisuke said, eager to move on from the topic of the old Sage. "My backup plan involves them. There is a kunoichi in Konoha who has inherited the Uzumaki's sealing techniques. While I don't have much contact with her, I am good friends with one of her friends. If Plan A fails, I'll ask her to study the seal on Han and try to free you as soon as possible."
"Then, Nara Keisuke," Kokuō said, its clear, sea-blue eyes seeming to peer into his soul. "If I am freed from Han's body, what will you do with me? Seal me up again, like Iwagakure did?"
"We already discussed this, didn't we?" Keisuke spread his hands, feigning confusion. "We'll have a fight. If I can defeat you, you'll sign a contract with me and become my summoning beast."
'Defeat me? I remember him saying his power had to be acknowledged by me...' Kokuō blinked but didn't correct him. This wasn't its demand; Keisuke was raising the stakes on his own.
"No, you misunderstand me," Kokuō said, shaking its head. "I'm referring to what happens after the summoning contract—or rather, after our battle."
"That?" Keisuke rubbed his chin and frowned. "Are you worried about your living situation? Come to think of it, I don't know much about what kind of environment Tailed Beasts prefer... What do you like, Kokuō? Forests? Plains? The ocean? If you like water, I might need to buy a large lake, since Konoha isn't on the coast."
The rapid-fire questions caught Kokuō off guard. The great white deer hesitated for a moment before speaking. "Um, actually, if it's possible, I'd prefer to be in a forest."
"A forest? That's it?" Keisuke's eyes lit up with excitement. "Kokuō, my clan happens to own a forest! It's big, it's comfortable, and it's full of Nara deer."
'I am not a deer!' The great white deer wanted to protest loudly and correct him, but the picture he painted was too tempting.
But... Kokuō gazed at the still-chattering Nara Keisuke, and the worries in its heart began to dissipate. At the very least, he wasn't planning on sealing it away in some dark, cramped space.
"I like forests."
"My clan happens to own one."
"I also like to climb mountains sometimes."
"My house is at the foot of Mount Kikyo—it's a large, tall mountain that surrounds Konoha."
"What about water sources?"
"Back when Hashirama Senju and Uchiha Madara fought, they created a place called the Valley of the End, which has a massive waterfall. There's also a river near the village called the Naka River."
On the topic of its future home, Keisuke and Kokuō quickly reached an agreement. Having successfully sweet-talked the great white deer, Keisuke finally got to his question.
"Kokuō, do you know how to use Boil Release?"
"Boil Release?" Kokuō tilted its head, answering without a hint of suspicion. "You just use Water and Fire style chakra at the same time. Fuse them together, and that's it."
The smile on Keisuke's face froze slightly. Kokuō had given him the right answer, but it was far too simple. Everyone knows that 1+1=2, but the question is why does 1+1=2?
"Looks like I need to rephrase the question," Keisuke said, bidding the beast farewell for a moment. "Wait here, Kokuō. I need to take care of something with Han's body first."
Kokuō nodded slightly. Keisuke's consciousness withdrew from Han's mind.
At present, the Jinchuriki's chakra was firmly suppressed by the Four Symbols Seal, making it impossible for him to mold any. Combined with the complex toxins Orochimaru had injected into him, Han was not a good research subject for Keisuke's "Boil Release tool" plan.
But after a few modifications, that could change.
First, Keisuke used the Delicate Illness Extraction Technique to remove some of the snake venom from Han's body. Then, using his own understanding of the Four Symbols Seal, he opened a tiny crack in the one Minato had placed. This would allow Han to retain and mold a certain amount of chakra.
Keisuke briefly woke Han.
"What..." Han's eyes fluttered open, his mind still groggy. Keisuke stared directly into them.
Genjutsu: Lacquer Eye!
A powerful stream of Yin Release chakra flooded Han's consciousness, confusing his senses and making him subconsciously begin to mold chakra. Once Han's chakra had reached a sufficient level, Keisuke decisively switched techniques.
Shadow Manipulation Technique!
Han's consciousness was sealed once more. Keisuke occupied his mind and reconnected with Kokuō.
"Kokuō, now, explain in detail how to use Boil Release."
Although it didn't know what had just happened, Kokuō suddenly felt a little sorry for Han... But compared to Keisuke, Han's importance in its heart was significantly lower. It quickly pushed the thought aside and began to personally instruct Keisuke on how to mold Boil Release chakra.
Of course, they were still using Han's body...
"A little more water..."
"Fire, this time..."
Under Kokuō's direct guidance, Keisuke quickly succeeded in creating Boil Release chakra within Han's body, and not just once.
Bidding Kokuō farewell again, Keisuke's consciousness returned to his own body.
"Summoning: Flash Blade Manifestation!"
Three masks appeared: a Water Style mask, a Fire Style mask, and a blank one—the usual materials for Kekkei Genkai fusion.
"If nothing else, the Fire Style masks are really being consumed quickly. Scorch Release, Explosion Release, Lava Release... they all needed one. Now Boil Release, too." Keisuke checked the reserves in his summoning seal. He had thought his supply of Nature Masks would last forever, but now he was actually facing a shortage, especially of the fire ones.
"I'll worry about that later. First, the Boil Release fusion experiment!"
Keisuke expertly took the Water and Fire masks and, following the experience he'd just gained, simultaneously infused their chakra into the blank mask. Aided by his previous successes, the creation of the new Nature Mask went off without a hitch. A moment later, a brand new mask appeared before him.
He picked it up, and a notification immediately popped up on his panel.
[B-Rank Ninja Tool Detected: [Nature Mask: Boil]!]
Keisuke's heart filled with joy.
"The fourth Kekkei Genkai, Boil Release, successfully mastered!"
