Kaito sat by his bedside, swirling a glass of wine in his hand, but his focus was entirely on the system interface before him.

It had been a year and a half since he regained the memories of his past life. At that time, his strength had undergone a complete transformation. Now, only the final three-tailed beasts stood between him and absolute mastery of this world. Once he had all ten, he would be truly unstoppable.

[System Notification] Reminder: When the Ten-Tails chakra is fully collected, it will immediately merge with the host's chakra! Due to the overwhelming power of the Six Paths level, and the host's current chakra being relatively weaker, the fusion process will take one year. During this time, the host will enter a deep sleep and will not awaken until the fusion is complete. Please choose a safe location for the final tailed beast integration.

Kaito frowned at the notification but quickly eased up.

"A year in hibernation, huh…? That's not too bad." He wasn't planning anything major for the next year anyway.

But another thought struck him, and he immediately asked the system, "What about when I fuse Sage Chakra and the Six Paths Yin-Yang Power? Will that take just as long?"

[System Notification] After fusing with the Ten-Tails chakra, the host will ascend to the Six Paths level. Since complete Sage Chakra and Six Paths Yin-Yang Power are also part of the same tier, their fusion will take less than a day.

"Good." Kaito let out a relieved sigh. If that fusion had taken years, it would have ruined his long-term plans.

However, this meant one thing—his travels would have to be put on hold for now.

With that in mind, he called a meeting with his companions.

Kaito gathered Tsunade and the others, looking around at their expectant faces before speaking calmly.

"There's been a change of plans. Our journey ends here for now. I'll be taking you all back to the Land of Water first."

Tsunade stepped forward, concern in her eyes. "Do you need any help?"

Kaito shook his head. "No, this is something I need to handle on my own."

She nodded, trusting his judgment.

Seeing no objections, Kaito continued, "For now, I'll have you all stay inside my dimension. It won't take long to return."

With a wave of his hand, he transported them all into his portable space—a vast realm now the size of a small town. Recently, he had ceased supplying chakra to its expansion and instead focused on developing a secondary battlefield: the Ice Domain, which had already grown to nearly a thousand square meters.

Activating Sage Mode, his senses stretched for dozens of miles. Then, using Heavenly Step, he rapidly advanced toward the Land of Water.

Kirigakure – Mizukage's Office

Inside the Mizukage's office, Terumi Mei was buried under a mountain of paperwork, with Uchiha Izumi assisting her. The Hidden Mist and the Land of Water were flourishing, and with that growth came an ever-increasing workload.

Without Izumi's help, Terumi Mei doubted she'd be able to keep up. She had considered hiring more personnel, but with Kaito absent, she didn't dare make such decisions on her own.

Finishing another thick document, she sighed and turned to Izumi.

"When your brother returns, you need to talk some sense into him."

"He is the Mizukage, you know," she muttered in frustration. "Yet he vanishes without warning, leaving all this work to us..."

Izumi giggled at Mei's complaints, but before she could reply, a voice cut through the room.

"Oh? Complaining about me already?"

Terumi Mei froze, while Izumi's face lit up in delight.

"Brother Kaito!" she called out joyfully.

A blur of motion and Kaito was suddenly seated in the Mizukage's chair, leaning forward with amusement in his eyes.

"I walk in, and the first thing I hear is you complaining," he teased. "Tell me, what exactly are you so unhappy about?"

Terumi Mei awkwardly scratched her head, avoiding his gaze. Seeing her flustered, Izumi stifled a laugh before trotting over to Kaito and grabbing his arm.

"Brother Kaito, Sister Mei was just joking!" she defended playfully. "Don't be mad."

Kaito glanced between the two, smirking. "When did you two get so close?"

Terumi Mei quickly averted her eyes, pretending to be deeply interested in the office walls. Kaito shook his head in amusement.

"Fine," he relented. "Let's get to business. Update me on everything that's happened while I was away."

Mei straightened up, her expression turning serious as she began her report.

After the Briefing

"You did well." Kaito nodded in satisfaction after listening to Mei's summary. The stronger the Land of Water became, the more it benefitted him.

Mei looked pleased with his praise but hesitated before speaking again. "There's one matter that requires your direct attention."

"Oh? What is it?"

She stepped forward and handed him a thick folder. "During your absence, the Anbu identified top-tier experts from across the ninja world. They've all arrived in Kirigakure, awaiting your orders."

Kaito flipped through the pages, skimming the list of names and backgrounds.

"Perfect. Have them compile their knowledge into written form," he instructed. "When the Technology Academy opens, they will be its first professors."

Mei nodded firmly. "Understood."

Seeing that all matters had been addressed, Kaito waved his hand, summoning Tsunade and the others from the portable space.

Kaito stood beside Terumi Mei as she frowned, her gaze fixed on Tsunade, who had suddenly appeared.

"You should have heard of her," Kaito said. "This is Tsunade, the first medical ninja in the ninja world."

"Starting today, she will be the head of the science and technology division."

"The village will fully support her in any research she wishes to conduct."

Terumi Mei hesitated for a moment but eventually nodded. "Understood."

Watching her reaction, Kaito sighed inwardly. It's a shame that I couldn't find Orochimaru. They would have been the best choice to lead this division.

Orochimaru's achievements in Kaito's past life were undeniable—intelligent robotics, artificial humans, reincarnation techniques… That level of technological advancement surpassed even the scientific developments of Kaito's previous world. It would have been invaluable to have them on his side. However, strengthening himself took priority. The search for Orochimaru would have to wait.

Just then, Kaito sensed two unfamiliar auras entering the Land of Water. His eyes narrowed as he activated his space-time technique to identify the intruders.

A moment later, his expression shifted.

Well, well… Seems like they came knocking on my door themselves.
