Naruto: AFK System

Yoruha simply smiled without answering. Tsunade didn't know what kind of powerful beings would appear during the Fourth Great Ninja War. 

With Yoruha's current strength, he wasn't yet capable of handling those formidable opponents. However, Yoruha didn't feel the need to explain.

Seeing Yoruha just smile without speaking, Tsunade frowned. "Do you think there's a ninja in the world stronger than you?"

Yoruha thought for a moment and said, "Even the Akatsuki members are already quite difficult to deal with. Does Lady Tsunade think I'm invincible in the ninja world?" "Isn't that the case?" Tsunade retorted.

For a moment, Yoruha didn't know what to say. He hadn't realized that Tsunade considered him so powerful.

"I am well aware of the kind of ninjas I might face in the future. If I can continue to grow stronger, surely others can too. 

Once someone achieves something in this world, it's possible for others to do the same. I don't believe there aren't stronger ninjas than me in this world. I'm not that optimistic."

Tsunade was silent for a long time. She didn't agree with Yoruha's perspective. In her eyes, Yoruha's strength was already absurdly high, even approaching the level of her grandfather. 

It wouldn't be long before Yoruha might reach her grandfather's level—the God of Shinobi, a ninja revered by his contemporaries.

But Yoruha's targets were Uchiha Madara and Ōtsutsuki Kaguya from the Fourth Great Ninja War, not Hashirama. 

Yoruha knew Tsunade wouldn't understand. In her understanding, Yoruha's power was already beyond her comprehension, and she couldn't imagine a ninja stronger than him.

Although Tsunade didn't agree with Yoruha, she couldn't think of a way to refute him. She could only say, "You should still be careful. Space-time ninjutsu is very dangerous." Not knowing how else to advise Yoruha, she said this.

Yoruha nodded. After staying there for a while, the three of them returned. Originally, Tsunade wanted to visit the casino, but with Yoruha around, she didn't go.

Back at the inn, Shizune found a note in the room. "Lady Tsunade, something's wrong, Naruto has been kidnapped," Shizune shouted.

Tsunade, who was sipping tea, was momentarily stunned. "Kidnapped? By whom?"

Tsunade couldn't understand. Naruto's strength wasn't weak, and the drugs in his system had long worn off. With his restored strength, Naruto was at least at the level of a Jonin.

Who could possibly kidnap him? Shizune looked at the note for a long time and shook her head, saying, "It doesn't say. It just says to bring money to the back mountain."

Tsunade thought for a moment and immediately understood what was going on. She stood up and sighed helplessly, "What a hassle. It must be debt collectors. Naruto really knows how to cause trouble for me." Tsunade knew Naruto's personality well.

He must have been persuaded by those chasing debts. There was no choice; Tsunade had to go and explain, or her image in Naruto's eyes would be ruined. Of course, her image wasn't that great in Naruto's eyes to begin with.

Shizune hesitated, "But Lady Tsunade, we don't have any money left." Tsunade laughed, "Who said we're going to pay?"

"Are you going to explain it, you know?" Tsunade had no intention of paying back the money. After all, it was the casino's money, and Tsunade planned to just let it slide.

As she reached the door, Tsunade turned to Shizune and said seriously, "Don't let Yoruha know about this, understand?" "But Naruto will definitely tell him." Tsunade thought about it and realized that was true.

"What a hassle. Never mind, let's head to the back mountain first." Tsunade carefully avoided Yoruha, afraid he would find out.

In fact, Yoruha already knew. Not only was he aware of this part of the plot, but his room was also not far from Tsunade's. Yoruha's hearing was exceptionally sharp, and he had heard everything clearly. However, Yoruha had no intention of getting involved.

In Yoruha's room, he finished reading about spatial techniques. He usually skimmed through books quickly.

After finishing, Yoruha pondered, "Combining sealing techniques with space-time ninjutsu should achieve my goal." With that, Yoruha drew a kunai and placed it in front of him. Sitting cross-legged, Yoruha began forming hand seals with unprecedented seriousness.

"There shouldn't be any problems, right? If something goes wrong, it might blow this place up." Yoruha wasn't very confident. If he made a mistake, the resulting spatial turbulence could have unimaginable destructive power.

Yoruha's hand seal speed was very slow, not because he was unfamiliar, but because he was uncertain. The next moment, Yoruha vanished from the room. He reappeared in the primeval forest of the back mountain.

There were too many people in the town; a mistake could cause massive casualties. He had to relocate to a forest several kilometers away from the town. 

Yoruha continued forming hand seals, taking over ten seconds to complete five seals. "It has to succeed."

As the last seal was completed, the chakra within Yoruha surged wildly. A black sphere of light suddenly appeared around the kunai in front of him. The black sphere was pure, with black arcs of electricity dancing on its surface.

Yoruha's eyes narrowed slightly. "What a terrifying chakra consumption. Such a small area has already drained a tenth of my chakra." The chakra consumption of this jutsu shocked Yoruha.

It's important to note that his current chakra reserves were second only to the Tailed Beasts like Kurama. 

Just a small spatial sphere had consumed a tenth of his chakra, which was indeed outrageous. Since his chakra had surged, he hadn't felt a tenth of it vanish so quickly in a long time.

The large-scale jutsus he used before seemed massive, and they did consume a lot of chakra. But for Yoruha now, those were just a drop in the bucket. Looking at the spatial sphere floating in mid-air, Yoruha clenched his fist.

Nothing happened. But Yoruha knew that the kunai inside the spatial sphere had already exploded violently. The moment Yoruha released his grip, the spatial sphere rapidly expanded, suddenly growing into a sphere about a meter in diameter.

Yoruha's eyes narrowed. "What terrifying power. I can't test it now. If this power is unleashed, it would likely be far more terrifying than a Tailed Beast Bomb." 

Yoruha's jutsu was designed to store massive energy within space, and once released, that energy would be unleashed at hundreds of times the chakra input by Yoruha. 

It's important to know that a tenth of Yoruha's chakra was comparable to the chakra contained in a full Tailed Beast Bomb.

Releasing energy hundreds of times that of a full Tailed Beast Bomb, Yoruha wondered what kind of battle would require him to use such a high-level jutsu. 

The chakra Yoruha input was merely to initiate the spatial sphere's operation; the energy released was stored by extracting energy from the space itself.
