Another rookie joined Training Ground 417 of Konoha: Uchiha Shisui, wielder of the ultimate genjutsu Kotoamatsukami. Of course, at present, he was merely a young boy who hadn't even awakened his Sharingan.
Lin Yu was incredibly dedicated to Shisui's training. After all, Kotoamatsukami was a cheat code, even with its decade-long cooldown. Lin Yu, however, mastered the power of Yang. While he couldn't shorten it to mere days, perhaps once every two or three years was feasible.
Furthermore, with Lin Yu around, Obito, Shisui, and the yet-to-be-born Itachi wouldn't have to worry about depleting their eye power. Initially, Lin Yu had planned to have Orochimaru research a reagent or liquid that could be fused with Hashirama's cells and absorbed into the body.
However, after acquiring the power of Yang, Lin Yu abandoned that idea. Compared to the instability of Hashirama's cells, the power of Yang was far more gentle and much more potent.
It was just that the quantity was limited. Lin Yu had to expend a third of his chakra to extract a single strand of Yang power. Moreover, there was a storage limit; he could only nurture three strands of Yang power within his body at a time, but they could be condensed again after consumption.
Still… I wonder if my cells can rival or even surpass Hashirama's cells. Lin Yu had once considered having Orochimaru research his own cells, but he ultimately refrained, feeling it was somewhat strange.
Never mind, it was better to let Orochimaru research the Ōtsutsuki clan. It was time to find an ally and search the entire shinobi world for Amado's whereabouts.
Another half a month quietly slipped by. Under Lin Yu's devoted tutelage, Shisui's progress was nothing short of miraculous. Graduating from the Ninja Academy was a certainty.
Lin Yu himself had also mastered several Lightning Style ninjutsu, such as the Lightning Release Chakra Mode. Although he was still a novice, most people found it difficult to distinguish.
It had to be said that the Lightning Release Chakra Mode was an excellent ninjutsu. It not only significantly boosted one's speed but also allowed for a layer of Lightning Release chakra to envelop the body, enhancing defensive capabilities.
However, the learning difficulty was indeed quite high. It required a sufficiently strong physique to withstand the Lightning Release chakra covering the entire body, as well as sufficient reaction time and coordination. Otherwise, merely boosting speed without proper control would be counterproductive.
But for Lin Yu, who possessed the Sage Body and the Sharingan, this ninjutsu was tailor-made. He had only observed the Raikage brothers' Lightning Release Chakra Mode during his memories of fighting them. After over ten days of his own exploration, he had initially mastered this ninjutsu.
During this period, he also owed a great debt to Kakashi's assistance, providing Lin Yu with many ideas for Lightning Style. As expected of Hatake Kakashi, who had already developed the A-rank ninjutsu Chidori, he was just lacking the Sharingan to effectively attack enemies, and further improvements were needed.
In any case, Kakashi wouldn't be getting Obito's Sharingan. However, it might be possible to get Kakashi a pair of the three-tomoe Sharingan, but he feared Kakashi wouldn't accept it without Obito.
I wonder if cloning technology can replicate the Sharingan. These scientific matters would still require Orochimaru's expertise to investigate. All in all, Orochimaru was that important to him; it seemed he needed to conclude the Third Great Ninja War quickly and subdue Orochimaru.
"Alright, no need to see me off, Kushina. I'll be back soon."
At the entrance of Konoha Village, Lin Yu was bidding farewell to Kushina. He was heading to the Land of Earth to help Hiruzen Sarutobi solve an urgent problem, so he could return to the village and alleviate his longing!
And also to raise the bounty on the Third Raikage! His treasure boy needed to be replaced!
"Mhm, be careful."
Kushina looked down at her toes, acting a bit shyly. "Lin Yu, do you think I'm too capricious and ignorant?"
Lin Yu was somewhat taken aback. Whose transformation jutsu was this? I can't even tell?
"Uh… are you Kushina?"
Kushina's beautiful eyes glared fiercely, and she gritted her teeth. "Does anyone else dare to impersonate me?"
"Uh… no, I was just a bit surprised."
Lin Yu consciousness drifted to his seal and asked Kurama, "Kurama, is this Kushina? Can you sense the presence of your other half?"
Kurama let out a haughty snort, too lazy to bother with Lin Yu, and continued to sleep with his eyes closed.
These humans are so weird!
Kushina stepped forward a couple of paces, wrapped her arms around Lin Yu's waist, and buried her head in his chest, blushing. "Come back soon. I'll be waiting for you at home!"
Then she closed her eyes, her fair and tender cheeks slightly lifted, as if waiting for something.
Lin Yu snapped back to reality after hearing Kushina's words and was stunned. Was this his Kushina? The little devil Kushina? This was outrageous!
Huh?
Lin Yu frowned. He seemed to have sensed a malevolent intent. He reached out, pushed Kushina away, and said, "I'll be back. This time, it shouldn't take too long."
As soon as Lin Yu finished speaking, he instantly vanished from the spot, leaving Kushina alone, tilting her small head at the empty air.
*Thump! Thump! Thump!*
Three blue veins bulged on Kushina's beautiful forehead. She said, word by word, "Uzumaki! Lin! Yu!"
Then, realizing she wasn't at home, Kushina quickly apologized to the stunned, unknown guardian god beside her and huffed away.
That smelly Lin Yu! Stupid Lin Yu! Why is he so insensitive!
And Mikoto too. Didn't they say that during farewells, one should say things like "I'll wait for you to come back," "I'll miss you," and "Don't forget me," then hug each other, tilt your face up 45 degrees to the sky, and you'll receive a passionate kiss from the other person?
Why was I pushed away directly?
That hateful Lin Yu! Don't you ever come back! Hmph!
…
Twenty kilometers outside Konoha, Lin Yu twisted the neck of a White Zetsu and casually tossed it aside. He frowned slightly: Was Uchiha Madara this impatient? Obito's body hadn't fully developed yet. Forcing the Mangekyo Sharingan now wasn't a good choice.
Uchiha Madara should also know that this was several years earlier than he anticipated and shouldn't be so rushed.
Could it be to monitor me? That's possible.
Lin Yu's thoughts raced. He still decided to proceed with his plan and head to the Land of Earth first. Uchiha Madara's goal was to bring Obito into his fold, to become a pawn for his resurrection. To make Obito fall into darkness, he had to witness Hatake Kakashi's tragic death with his own eyes, and preferably die at the hands of his teammates, such as Rin Nohara, Uzumaki Lin Yu, or even himself!
Therefore, as a precaution, Lin Yu gave Kakashi an Immortal Underworld Flame. If Kakashi's life was ever threatened, Lin Yu could arrive instantly.
If only Lin Yu knew where Uchiha Madara's base was, he would truly want to say to Uchiha Madara: "Hey! Tricking Obito? Count me in! I have tons of tricks up my sleeve!"
