5. Haki, Rokushiki, And Life Return

"How about this room? Do you need two rooms?" 

Hancock quickly led Uchiha Sora and Uchiha Mikasa to a spacious, elegant cabin and asked. 

"One room is enough!" 

Uchiha Mikasa glanced around, nodded in satisfaction, and then inquired, "By the way, how long does it take to get to Sabaody Archipelago from here?" 

"Hmm..." Hancock hesitated before replying, "It will probably take one or two days. Is that a problem?" 

She still had a favorable impression of Uchiha Mikasa and Sora. If not for their intervention, she and her crew might have been captured and enslaved. 

"No, nothing. Just curious!" Uchiha Mikasa said, gesturing for Hancock to go. "You should get back to your duties. Many of your companions still need your help. Come back when you're done!" 

"Well, thank you! I'll check on them first and return later. Also, I'll prepare some food for you," Hancock replied before leaving quickly. 

Uchiha Mikasa led Sora into the cabin and closed the door behind them. 

She turned to him and said, "It seems like you know a lot about little Hancock and this pirate crew. Tell Mom about it!" 

"Okay!" Uchiha Sora agreed without hesitation and began sharing everything he knew. 

"Huh?" 

Uchiha Mikasa was intrigued after listening. "Most of the female warriors of Amazon Lily, all of whom are women, have mastered Armament Haki, and some have mastered Observation Haki. They possess an inheritance of two-color Haki? That's quite remarkable!" 

"This reminds me of a place in the ninja world called Nadeshiko Village. It's similar to Amazon Lily in that it's an all-female society." 

When Uchiha Sora heard the mention of Nadeshiko Village, he immediately thought of Jiraiya. In the future, that guy seemed to have a peculiar connection with Nadeshiko Village, even dragging Naruto into it! 

"So, what do you think about asking for the training method for two-color Haki as a reward?" Uchiha Mikasa asked, clearly curious about the power system of this world and eager to study it. 

From Sora's descriptions and her own observations during the earlier battle, both Observation Haki and Armament Haki were of immense value. 

"It's better not to!" Uchiha Sora shook his head firmly. "That's part of Amazon Lily's inheritance. Not only would it likely be rejected, but it could also offend them. It's not worth the risk." 

"Next, they're going to meet their former captain, Shakuyaku, the previous empress of Amazon Lily. She's at least a master of two-color Haki. She also has an exceptional intelligence network." 

"Her lover, Silvers Rayleigh, the former vice-captain of the Pirate King, will also be there. Rayleigh is a super-strong Grandmaster of Haki. In terms of power, he should be stronger than most Kage-level shinobi. Even if he isn't quite at the level of the First Hokage Senju Hashirama or Uchiha Madara, he wouldn't be far behind." 

"We could ask Rayleigh or Shakuyaku for their Haki training methods, as well as techniques like Marine Six Styles or Life Return. This approach would be much safer and won't be misunderstood as coveting the Haki inheritance of Amazon Lily." 

"What do you think, Mom?" 

"Many times, requesting secrets tied to racial inheritance causes unnecessary misunderstandings." 

"Huh?" 

Uchiha Mikasa was momentarily stunned. "A strong man comparable to Uchiha Madara? The Haki training experience of someone like that should indeed be more valuable. Do you think they'd agree to share it?"

"If possible, your idea is definitely better," Uchiha Mikasa acknowledged, her voice thoughtful. 

At the same time, she couldn't help but marvel inwardly. There seemed to be far more top-tier strong individuals in this world compared to the ninja world. Considering the vast population and size of this world, however, it felt natural. 

This world was indeed much larger than the ninja world. 

"It shouldn't be a problem!" Uchiha Sora replied confidently. "Neither Shakuyaku nor Rayleigh are the type to be stingy. They're both honorable and grateful people." 

"At most, I'll offer them information they won't be able to refuse as a trade." 

"Whether it's Haki training, Marine Six Styles, or Life Return techniques, I'll take any of them!" 

Opportunities like this were rare. Sora had initially assumed he wouldn't gain access to such valuable resources so quickly. Now that he had the chance, he wouldn't let it slip through his fingers. 

"Since you're so confident, we'll go with your plan," Uchiha Mikasa agreed without hesitation. However, she asked curiously, "What exactly are Marine Six Styles and Life Return? Why do they seem so significant to you? Do they have something to do with the Marines of this world?" 

"Yes," Sora confirmed. "They're directly related to the Marines, or more specifically, the World Government. These are superhuman techniques that develop human potential and significantly enhance physical abilities." 

"They're also considered foundational skills for systematic two-color Haki training. Once someone masters the Six Styles, they're usually not far from awakening Armament Haki and Observation Haki." 

"Of course, that's not the main draw," Sora continued. "The real value is that mastery of the Six Styles opens the door to a further skill: Life Return." 

"This technique greatly accelerates physical recovery, enhances digestion efficiency, and allows for the rapid conversion of food into vitality. It even enables the practitioner to control every cell of their body." 

Sora paused briefly. "For us, this ability could drastically improve recovery times and even replenish life energy. It's something I can't afford to pass up." 

After Sora explained the basics, Uchiha Mikasa's eyes lit up with understanding. 

"Strengthening digestion and recovery, controlling every inch of one's flesh and blood... it truly is an extraordinary skill!" 

"If it helps with cellular energy recovery, could it also improve chakra recovery?" 

"Exactly," Sora affirmed with a nod. "That's why it's so important. Of course, mastering Life Return is extremely difficult. In the entire pirate world, only a select few geniuses have managed it." 

"Even among CP9, an elite group where every member has mastered the Six Styles, only Rob Lucci was able to master Life Return. That speaks to its difficulty." 

"Difficulty doesn't matter! As long as we get the training method, I'm confident I can learn it," Uchiha Mikasa said resolutely. 

Her eyes gleamed with determination. She was, after all, a genius herself. 

"Hehe! That's the spirit!" Sora laughed at his mother's confidence before adding, "By the way, I'm sure you've noticed, Mom—people in this world are significantly stronger than those in the ninja world." 

"Yeah," Uchiha Mikasa agreed with a firm nod. "I noticed that a while ago. It's probably related to the environment of this world, right?" 

She continued, "I've sensed it. The oceans of this world teem with creatures of enormous vitality and size. This is just the shallow sea. The deeper layers must harbor even more powerful sea beasts." 

"And the human physique here seems fundamentally different from the people of the ninja world," she mused. 

"I think it's mainly the environment," Sora reasoned. "The oceans here are home to super Sea Kings that can stretch thousands of meters, with countless others measuring tens or hundreds of meters. 

"Even on land, beasts of enormous size are common." 

Sora then suggested, "We could regularly hunt Sea Kings or land beasts for food. Paired with proper health-focused training, this could speed up recovery, strengthen our bodies, and even restore vitality. What do you think, Mom?"
