Chapter 71

Dark sewers.

Water dripped rhythmically from the cracks in the iron pipe above. Several candles hung on the orange-red earthen walls, their flickering flames casting dancing shadows.

"Is this…the sealed world of Kyuubi?"

Kazuki looked at the surrounding scene with a solemn expression. This place gave him a very dangerous feeling. Even though his strength had surpassed the average shadow level, he still felt uncomfortable. The Nine-Tails was full of resentment toward humans, and its chakra was evil and terrifying. Even without seeing Kyuubi yet, Kazuki could sense the malicious chakra aura in the air!

Sure enough, it is not groundless that villains have a bonus to their strength. There is a noticeable difference between someone who fights mercilessly and someone who shows restraint in every attack. This is why some villains become weaker when they switch to the side of justice.

Kazuki walked through the sewers, taking several turns until he reached a cave entrance. There was no door, just an iron fence visible from a distance.

"Who's there!"

Before Kazuki could speak, a cold voice came from the entrance of the cave. Ignoring the warning, he walked straight in and finally saw Kyuubi clearly in the firelight—over ten meters tall, with orange-red fur, sharp teeth, and huge claws. The most striking feature was its nine swaying tails.

"You brat, why are you staring at me?"

Being silently watched by Kazuki made Kyuubi feel uncomfortable. Shouldn't ordinary people be terrified when they see me? How is this kid so calm? And how did he get in here?

Kazuki sneered, his eyes suddenly turning into red magatama.

"Damn it, it's that Uchiha brat again!" Kyuubi roared when it saw the Sharingan. Memories of being controlled by Uchiha Madara and Uchiha Obito flooded back, filling it with rage. Huge claws slammed against the iron fence, making a loud noise, but the seal remained unbreakable.

Kazuki's Sharingan began to rotate. "Sharingan. Genjutsu!" With this, Kyuubi's eyes also transformed into Sharingan. Kazuki controlled the Nine-Tails using the power of his two-tomoe Sharingan, a feat typically reserved for those with the Mangekyo Sharingan.

"The only difference between my Sharingan and Mangekyou is a few exclusive techniques. I think I still have a chance against Uchiha Itachi," Kazuki murmured. He hadn't come here to help Naruto control chakra but to test his Sharingan's strength.

Kazuki inspected the seal on the iron fence. If removed, Kyuubi could break free, but that wasn't what Kazuki needed. Controlling Kyuubi's chakra without disturbing Uzumaki Naruto, he exited the sealed space.

Back in the outside world, only a moment had passed. Neither Naruto nor the ANBU ninjas noticed anything amiss.

"Naruto, next, I'm going to teach you a method of controlling chakra. Master this, and you'll never fail with the Clone Technique."

"Really? Teach me quickly!" Naruto exclaimed, eyes gleaming with determination. Kazuki walked up a tree, demonstrating by attaching chakra to the soles of his feet, achieving the effect of climbing.

"This is a skill every ninja must learn. Once mastered, most low-level ninjutsu will be a breeze," Kazuki explained. Naruto eagerly tried, but as expected, he stumbled repeatedly. Despite the influence of Kyuubi being under control, Naruto's reckless nature made precise chakra control difficult.

Kazuki patiently guided Naruto. After a night of training, Naruto finally mastered the tree-climbing technique.

"Clone Technique!"

With a puff of smoke, an identical Naruto clone appeared beside him. "Yeah, I did it!" Naruto cheered, jumping in excitement.

Kazuki smiled, though inwardly exhausted. Finally, Naruto had achieved something significant.
