Entering Tsunade

On the day of the Survival Exercise, Wu Yu had said that the essence of the Sharingan was "an automatic converter for high-quality Yin Release Chakra." With the Sharingan, he originally had no need to specifically train Yin Release transformations, but...

"It's basically an ancestral wheelchair!" Wu Yu had later mocked the Sharingan. "Just like your Uchiha clan's Fire Release bloodline—you don't need to deliberately train it; it comes naturally as soon as you get the hang of it. The Sharingan is the same. Once it awakens, there's no need to cultivate Yin Release. It automatically refines ocular power—that is, high-level Yin Release Chakra..."

Sasuke trained alone in the deathly silent old estate late at night.

If he could cultivate Yin Release Chakra on his own that was no weaker than the Sharingan's ocular power—or even of higher quality—then... could he also push the Sharingan to an even higher level?

"Super Sharingan..."

Kakashi Hatake glanced at Wu Yu beside him, who eagerly pulled out a manuscript. "You mean the Mangekyō Sharingan rumored to exist within the Uchiha clan? This child's Sage Mode sensory abilities are very strong, so it should be true. But to say that my left eye already possesses the potential for the Mangekyō..."

"What are you spacing out for?" Wu Yu urged. "Hurry up and read it. I changed some of the protagonist's initial settings. Give me some advice, old hand."

Kakashi flipped through it. The premise of someone from the ninja world transmigrating into another world was like the finishing touch to a painting, completely reversing the sense of distance the story had previously carried and making it immensely immersive. The martial arts setting and jianghu world he had originally found somewhat uninteresting now brimmed with the thrilling novelty of the unknown.

But why had the protagonist been an Uchiha in his previous life?

Having once been a ninja in the Hokage's Anbu, Kakashi keenly noticed how evasive Wu Yu had been when describing the circumstances of the protagonist Uchiha Mori's death before his transmigration...

He did not think Wu Yu would expose any conspiracy behind the Uchiha clan massacre. Rather, he suspected that this Uchiha Mori—Yang Guo—might have been modeled after either Itachi Uchiha or Sasuke Uchiha.

Wu Yu instead looked as though he found the question strange, replying with complete confidence, "Uchiha are popular! Even the lords and daimyo of various countries are huge fans of them. If I use an Uchiha as the protagonist, maybe it can even sell in the Capital of Fire!"

"So that was your consideration..." Kakashi was speechless, yet he had to admit that Wu Yu was right. Whenever an Uchiha participated in the Chunin Exam, even the number of lords and nobles who came to watch would be two or three times higher than usual. That was the Uchiha's popularity.

Konoha's celebrity clan had been destroyed by the star among the stars within their own clan...

But it was also fortunate that the Uchiha had already vanished into smoke. Otherwise, there was no way a novel like this could be openly published and sold—did they really think Uchiha blades were dull?

After finishing the day's mission, Kakashi rested briefly in his apartment before standing before the mirror. He pushed up his forehead protector, exposing his scarlet Sharingan, and met the gaze of Obito's eye in the mirror...

Could it be that when he had killed Rin all those years ago, this eye had actually already begun transforming toward the Mangekyō Sharingan?

At the time, he really had seemed to faint mysteriously...

Kakashi refined Chakra toward his left eye. Whether this Sharingan had evolved into a Mangekyō or not, he needed to quickly readjust to it. If he had to be carried home by a few students again, that would be far too embarrassing.

As for the ten-chapter sample Wu Yu had given him, Kakashi had also confirmed that it was very erotic—and very satisfying. It would definitely sell well. He had become a loyal reader, and this dignified Jonin had decided to bring his own provisions while helping contact publishers, all so he could read the next chapter as soon as possible...

"This kind of mission is such a waste of time. Hurry back and write."

The setting sun shimmered in the stream as Wu Yu carried a basket on his back and used long-nosed pliers to pick garbage out of the water.

Having all learned tree climbing and water walking, Team Seven and Team Zero truly were born with the sacred physique for cleaning river trash among this batch of Genin...

Hearing Mysterious Kaguya's indifferent voice in his ear, Wu Yu replied helplessly, "The first volume already has enough material. Let me rest for a while, my dear grandma..."

Mysterious Kaguya fell silent.

That evening, after the garbage-collection mission was turned in and the reward received, the team disbanded on the spot.

Before leaving, Wu Yu tightly clasped Kakashi Hatake's hand and shook it vigorously. "Comrade Kakashi, I'm leaving the publishing matter to you."

Kakashi clasped his hand in return, revealing a determined one-eyed look. "Leave it to me!"

Anyone who did not know better would think the two were doing something momentous...

Sasuke Uchiha and Sakura Haruno rolled their eyes and left separately, while Naruto Uzumaki was the only one who had no idea what was going on...

"Time to go back and write..."

Wu Yu had only taken a few steps after leaving when Mysterious Kaguya's nagging voice sounded in the air again.

Come on, can't you really just let me rest "for a while"?

Wu Yu said helplessly, "I have plans today. Tsunade asked to see me last night. We agreed to meet today."

Mysterious Kaguya fell silent again...

"Meet up, meet up... It seems she never said where we were meeting?"

Wu Yu walked down a street in Konoha, somewhat at a loss. He seemed to have forgotten to ask where Tsunade's home in Konoha was... Should he summon a Slug to ask?

"Tsunade entered me last night. Now it's time for me to enter her!"

Wu Yu's consciousness sank, arriving at the water's surface in his mental world. After giving Jade Rabbit a few instructions, he merged with her Chakra and transmitted himself toward the other end of an indistinct connection.

In Tsunade's mental world, Tsunade leaned against Haotu's enlarged body. The water before her suddenly surged with a SPLASH..., and Wu Yu appeared, holding Jade Rabbit in his arms.

Wu Yu looked at Tsunade and noticed that her cheeks were flushed red. Surprised, he asked, [Did you get drunk?]

[...] Tsunade did not answer. She glanced at Wu Yu as he walked over. [Is there something you wanted to ask me?]

Wu Yu pointed at the dark red Yin Seal on her forehead. [After you came over last night, I looked through the scrolls you left behind. This technique was in there—is it the Yin Seal?]

[And?] Tsunade slapped away the little brat's paw.

Wu Yu laughed. [Haha, I can't understand any of it!]

Tsunade said, [The Yin Seal is rather special. Whether as Medical Ninjutsu or Fuinjutsu, it is very special... And you know neither, so it would be strange if you could understand it.]

[So Auntie decided to come personally instruct me?] Wu Yu asked with a grin.

[...] Tsunade suddenly said, [Instead of wasting time joking with me here, you should activate Jade Rabbit Mode and see whether anyone is following you.]

What did that mean?

Had that old bastard Danzo come looking for him?

Back with Wu Yu's physical body, a dark red Three-Eyed Mask appeared on his face. As his ears became pointed, he casually pulled up the hood of his sleeveless jacket. Sure enough, he sensed Jonin-level Chakra steadily following him.
