Naruto: Can't learn ninjutsu? I'll just practice immortality!

After sending Yaoli back to the Land of Demons, Asakawa Naoki left behind a few Senzu beans and transformed himself. When it was light, he led Rope Tree and Masamura Oki back to Konoha Village.

He himself came to the Sky City through the teleportation array, ready to upgrade the energy facilities of the Sky City with the captured ghosts.

However, in addition to him, Miroku, the three little ones and Uzumaki Kaori followed him.

In Miroku's words, she was new here and only knew Asakawa Naoki, so she had to follow him.

The three little ones and Uzumaki Kaori wanted to know more about the structure of the Sky City.

"Okay, this is the most important device in the Sky City." Asakawa Naoki led a group of people to the front of the energy room.

Opening the door of the energy room, there was the Zero-tailed Void, which was dozens of meters long, like a big earthworm, emitting extremely dark chakra.

Looking at the ugly and terrifying Zero-tailed, the people present, except Asakawa Naoki, felt a little uncomfortable, and the darkness in their hearts seemed to be aroused.

Konan and Yahiko recalled the sadness and fear in their hearts when they were spitted and chased when they were wandering in the past, while Uzumaki Kaori remembered the helplessness of those guys in Kusagakure Village when they bullied her, and the resentment when Uzumaki Village was destroyed.

Even Nagato and Miroku, who did not experience too much suffering and had intact families, felt a little uncomfortable at this moment, recalling those bad situations in the past.

"Zero-tail?" Miroku frowned and asked:

"Aren't there only nine tailed beasts? When did a zero-tail appear?"

"Besides, I always feel uncomfortable in front of it."

The three little ones and Uzumaki Kaori also looked at Asakawa Naoki, waiting for his explanation. According to the knowledge they learned, there are indeed only one to nine tails in the ninja world.

"That's right, there are only nine tailed beasts. Zero-tailed Void is not a tailed beast, but a man-made monster created by an ambitious person using the dark chakra in people's hearts." Asakawa Naoki explained:

"I defeated that ninja, and then captured Zero-tailed Void to use as energy to drive Sky City."

"Zero-tailed will evoke the darkness in people's hearts. The more darkness there is, the stronger Zero-tailed will be."

"The darkness in people's hearts will not disappear, so the power of Zero-tailed is also close to infinite."

"Hehehe!"

Zero-tailed Void laughed chillingly when he saw the group coming, and quickly rushed towards the position of several people.

"Danger!"

Miroku stood in front of Asakawa Naoki. She had always been protected by Asakawa Naoki. Now that she has gained powerful power, it's her turn to protect Asakawa Naoki!

However, just as Miroku was about to use her best sealing technique to seal Zero-tailed Void, Asakawa Naoki put a hand on her shoulder to stop her action.

"Relax, don't worry."

As Asakawa Naoki's voice fell, the ancient runes engraved on the wall of the energy room and the prohibitions that Asakawa Naoki later refined exerted their power at the same time, and dozens of golden chains bound the Zero-Tailed Void tightly.

"Hehehe!"

The Zero-Tailed Void struggled desperately, but in front of the golden chains that could extract chakra, its struggle was meaningless. In the end, it became more and more powerless, and became like a salted fish, allowing the chains to block it.

After the Zero-Tailed Void was locked by the chains, several people present breathed a sigh of relief and felt much better.

"There are two kinds of sealing techniques in it, both of which I have never seen. It can easily suppress a monster like Zero-Tail. It's amazing." Maitreya said with interest.

"Haha, one of the sealing techniques in the energy room is an ancient sealing technique, and the other is the one I engraved later." Asakawa Naoki smiled and said, "I'll have a chance to teach you in the future."

"Teacher, can we learn it too?" Xiaonan looked at Asakawa Naoki expectantly.

"Forget it, I'm an expert in sealing techniques." Miroku waved his hand and said.

"Humph, we are the teacher's disciples. As long as we want to learn, the teacher will teach us!" Xiaonan said unwillingly.

Seeing that the two were about to quarrel, Asakawa Naoki interrupted:

"Okay, if you have time to learn in the future, I will definitely teach you."

"But I have to remind you that ninjutsu is more about quality than quantity, and you still need to practice more."

"Got it."

Sensing that life in the Hidden Rain Village might not be peaceful in the future, Asakawa Naoki sighed lightly and put the sealed Wuliang in the spirit beast bag into the energy room.

At the moment when Wuliang appeared, the Zero-Tailed Void, which was originally in a state of salted fish, attacked the Wuliang that invaded its territory.

The body of the Wuliang is like a giant octopus. After the seal is lifted, its body begins to grow rapidly. One of its tentacles is dozens of meters long. Its entire body is nearly twice as large as the thin dog-like Zero Tail Void.

"Damn ninja!"

"Damn witch!"

The Wuliang was about to start a killing spree, butBeing grabbed by Zero-Tailed Void's arms, the power in his body was slowly absorbed by Zero-Tailed Void.

"What the hell are you?" Wuliang cursed angrily, "How dare you absorb my energy?"

The next moment, Wuliang swung more than a dozen tentacles to hit Zero-Tailed Void, but found it difficult to cause damage to Zero-Tailed Void.

"Hehehe!"

Zero-Tailed Void, who had no IQ, laughed wildly while absorbing Wuliang's chakra, and immediately made Wuliang red-hot.

More than a dozen tentacles began to continuously penetrate the body of Void, and even worked together to tear Void into several pieces.

But not long after, Zero-Tailed Void's body merged together again, and continued to absorb Wuliang's energy, and continued to laugh evilly.

"Hehehe!"

"Damn bug!"

The Wuliang was completely enraged, and even ignored Asakawa Naoki and Miroku, who caused it to be sealed and were now watching the show, and focused on dealing with the Zero-Tailed Void.

So, Asakawa Naoki and his group stood at the door to watch the Wuliang fight the Zero-Tailed Void, and the octopus fight the earthworm.

In fact, the comprehensive strength of the Wuliang is definitely not comparable to the Zero-Tailed Void.

But the Zero-Tailed Void can absorb chakra and is difficult to kill, which makes the Wuliang extremely uncomfortable.

The two undead monsters fought for a long time, but the huge energy room was indestructible and solid.

At a certain moment, when the intensity of the battle between the two escalated, countless golden chains appeared on the stone wall of the energy room, tightly entangled the bodies of the Zero-Tailed Void and the Wuliang, and began to absorb the chakra of both as energy.

When the golden chain was loosened, Zero-Tailed Void and Wuliang had become two salted fish that had been drained.

"Okay, let's go." Asakawa Naoki said.

"Is it really okay to leave Wuliang here?" Miroku asked with some concern.

"Don't worry, Wuliang can't escape." Asakawa Naoki said.

If the previous energy room may not be able to trap Wuliang, then the energy room reinforced by him can even withstand the Tailed Beast Ball.

Wuliang's strength may not be weaker than the tailed beast, but it does not have a high-damage trick like the Tailed Beast Ball.

There is also Zero-Tailed Void, which is very smart and can absorb Wuliang's chakra at any time, not to mention that the Sky City is his magic weapon. Wuliang is in the Sky City, just like a bird in a cage, under his control.
