Naruto Law of the Devil

The next morning, Yu was woken up early by a knock on the door from Uchiha Sasuke.

Preoccupied with the appearance of the Otsutsuki Clan descendants on the moon the previous night, Yu had only now remembered that he had promised Sasuke to guide him in training for three days.

"Speak up, kid. What do you want to learn…"

After arriving at a regular training field in Konoha, Yu, yawning, looked at Sasuke and said, "Aside from the Sharingan's Dojutsu, which I can't teach you, I've dabbled in pretty much everything else—Taijutsu, Ninjutsu, Genjutsu, even Medical Ninjutsu."

"My goal is to kill that man… so, of course, teach me the strongest Ninjutsu you can!!"

Staring at Yu, who seemed lazy and indifferent, Sasuke's black eyes silently transformed into the crimson two-tomoe Sharingan, his fists clenched tightly.

After the Chunin Exams and the Konoha Destruction Plan, both Gaara, the One-Tail Jinchuriki from Sand with his immense power, and Naruto, whose strength had surged dramatically, had deeply provoked his fragile pride.

Especially after encountering Itachi again and being defeated by him so easily, coupled with the cruel mental blow of Tsukuyomi, his mind began to develop an almost pathological obsession and craving for power.

Itachi, is it really worth it… to create such a false image for your brother with such painstaking efforts…

Sensing the intense desire for power reflected in Sasuke's eyes, Yu couldn't help but feel a pang of sympathy.

"Alright, kid…"

"To defeat Itachi, the first thing you need to do is face the facts…"

Retracting his thoughts, Yu looked at Sasuke, who barely reached his chest in height, and began to explain, "With your current strength, barely reaching Chunin level, even if I taught you the most powerful Ninjutsu, you wouldn't be able to use it effectively."

"Ninja battles are unpredictable. The strength of a Ninjutsu doesn't necessarily correlate with its level. If used correctly, even the Academy-level Three Basic Jutsu can be enough to accurately kill an opponent."

As he spoke, Yu couldn't help but recall his first encounter with a Jonin, where he had used Shadow Clone Jutsu and Transformation Jutsu to defeat the Mist Jonin.

"Kakashi should have taught you Chidori by now, right?"

With his gaze returning to Sasuke, Yu said, "If I remember correctly, your Chakra affinities are Lightning and Fire, while mine are Lightning and Water. So, I'll teach you how to control the form transformation of Lightning Release!"

Form transformation?

Upon hearing this unfamiliar term from Yu, Sasuke widened his Sharingan slightly. Although he knew from Kakashi that the powerful Lightning Release Ninjutsu, Chidori, was developed by this man, the concept of Chakra form transformation was still relatively new to him.

Lightning Release: Chidori!!

Seeing Sasuke's bewildered expression, Yu said nothing more and simply performed the hand seals to release Chidori. The intense and brilliant lightning surged and concentrated in the palm of his right hand.

"This is the basic form of Chidori…"

After demonstrating the basic form of Chidori in front of Sasuke, and noticing his unwavering attention, Yu's expression became more serious. "Next, watch closely with your Sharingan. I'll only show you once…"

Lightning Release: Chidori Sharp Spear!!

Before Sasuke could react, the light from Yu's Chidori surged explosively. The powerful, uncontrollable Lightning Release Chakra in his hand transformed into a sharp, controlled light blade, which was thrown and instantly pierced through a large tree outside the training field through a gap in the iron fence!

"This is… Chidori turned into a spear-like form and thrown to penetrate the target?!"

Witnessing the Chidori Sharp Spear up close, Sasuke's crimson Sharingan erupted with a dazzling light. "Changing the shape of Chakra, altering the form of Ninjutsu, controlling the power and range of the technique—this is form transformation?!"

"It seems you've grasped the concept…"

Seeing that Sasuke seemed to have understood the essence of form transformation, Yu nodded in satisfaction. "Perhaps I should revise my previous assessment of you. Although you don't compare to Itachi and Shisui, you're quite impressive given the current peaceful era…"

After all, the inspiration for the Chidori different uses originally came from Sasuke in the Shippuden series. Perhaps in return, Yu decided to teach him some Ninjutsu derived from Chidori ahead of time.

Whether he can master and use them will depend on his own talent and effort. Given that Sasuke at this time can only use Chidori up to twice a day, techniques like Chidori Current might still be a bit early for him.

...

"Hey! Konoha!!"

"We're back!!"

After teaching Sasuke for a while, a familiar loud voice suddenly came from the direction of Konoha's village gate, drawing the attention of both Yu and Sasuke.

"Tch, it's that guy Naruto…"

Upon recognizing Naruto's voice, Sasuke clicked his tongue and involuntarily displayed a complex expression. Since Naruto trained with the legendary Sannin Jiraiya and his strength surpassed Sasuke's, an invisible rift had inevitably formed between them.

Jiraiya… and Tsunade as well…

Refocusing his gaze, Yu saw Naruto and the others entering Konoha through the village gate. Besides Jiraiya, there was also a woman with light blonde, parted hair walking beside him.

She looked to be in her early twenties, with fair skin and a beautiful appearance. She wore a green long coat with the character for "gamble" written on the back. Her impressive figure drew the attention of all the men around her.

"Let's end today's training here…"

"It seems Konoha will soon welcome its Fifth Hokage…"

After seeing Tsunade return to Konoha, along with Shizune following her, Yu silently withdrew his gaze and spoke to Sasuke.

It appears that events are following their original path. Tsunade could not escape her fate of being persuaded by Naruto's Talk no Jutsu to return to Konoha as the Fifth Hokage. Since Orochimaru's hands were not sealed by the Third Hokage, there's no reason to seek Tsunade's treatment as in the anime…

Fifth Hokage?

Hearing Yu's words, Sasuke was taken aback and, following his gaze, saw Tsunade walking ahead of Naruto. Could she be that woman…?

"Speaking of which, that difficult woman is actually an elder…"

Noticing Sasuke's surprised look, Yu gave a wry smile and shook his head. "Despite her outward appearance of always resisting Konoha, she actually loves Konoha more than anyone else… After all, this place holds all her past and bonds…"

Although the last time Yu saw Tsunade, she was in a drunken state, Yu knew very well that beneath her seemingly carefree and bold exterior, she actually had a very delicate nature.

But now that this troublesome woman has returned to Konoha to assume the position of the Fifth Hokage…

It's also time for me to prepare to leave Konoha once again… and start implementing my plan…

Just as Yu was about to say goodbye to Sasuke and leave, a gust of wind blew, and two unexpected figures suddenly appeared in front of him and Sasuke.
