"There are already some clues!"
Uchiha Sarah shook her head. "During this period, we sent people out to investigate the news. Three days ago, word from the country of Kawano was that a giant eagle ninja beast had been found!"
She paused, letting the weight of the revelation sink in. "If everything goes according to plan, it should be brought back in the next two days."
"But there's another problem," she continued, her tone turning cautious. "Can the ninja beast be taken directly to the pirate world, or does it also need to be bound by a contract? Does it require cultivating favorability with this ninjutsu first?"
Ethan, listening intently, was slightly stunned. He furrowed his brow and said, "It depends on the degree of its wisdom. If it possesses complete wisdom, then yes, you need to cultivate favorability. But if it lacks a complete consciousness, you might force a contract or simply use the space-time gate as a transit."
He explained further, "This restriction is really to protect our safety. Otherwise, things could easily go wrong. If the beast isn't taken across the world properly and is just placed in the space-time gate's space, there aren't many restrictions. As long as it loses its ability to resist, it can be safely confined."
Ethan recalled, "Remember when Rayleigh was tasked with hunting Sea Kings? The higher the level of the Sea Kings, the more complete their wisdom. Some super Sea Kings over a thousand meters long even have their own language and can communicate with humans."
Uchiha Sarah nodded in agreement. "Then you probably have to cultivate the favorability of this ninja eagle first," she advised. "Ninja beasts generally have complete wisdom, and some can even speak human language directly."
Ethan smiled, accepting the challenge. "Alright, then I'll cultivate its favorability when the time comes. Ninja beasts aren't as complex as humans—their minds are simpler and their favorability is easier to improve. I'll feed it more Sea King meat or give it nutritional pills, and it should meet the binding requirements soon."
He added with a laugh, "It would be great if humans were that simple!"
"That's right," Uchiha Sarah agreed. "Then let's do it!"
A few hours later, Ethan had finally read through all the sealing techniques and related knowledge he'd obtained. He even managed to study the Flying Thunder God Technique scroll thoroughly, memorizing all the information. Of course, mastering everything would take a lot more time, but this was just the beginning.
...
After dinner, Ethan officially began practicing Chakra. This was his first time practicing Chakra since he successfully awakened his talent after extracting it for the first time. As he focused, he noted with satisfaction that the entire extraction process had been extremely smooth.
It was far less difficult than before. With each extraction, Ethan found that synthesizing Chakra became easier. Even a small amount of extracted energy produced a tremendous boost—each cell now held energy dozens, even hundreds of times more than just a month ago.
After another successful extraction, Ethan did not pause. He plunged into practicing his Chakra refining technique and the skill of counting breaths to raise his Chakra limit.
[You have practiced Chakra Refining, proficiency +30, Chakra +10.]
[You have practiced Chakra Refining, proficiency +40, Chakra +10.]
[You have practiced Chakra Refining, proficiency +52, Chakra +12.]
As his proficiency steadily increased, so did his ability to extract and synthesize cell energy. With each practice session, the total amount of Chakra in his body continued to rise. There's a saying among ninjas: the Chakra capacity is finite and cannot be increased by ordinary methods. Once you master energy extraction, further growth depends on your body's ability to produce more Chakra as you mature—or by tempering your body to strengthen cells and boost their energy capacity.
Of course, mental strength must develop in tandem with physical ability. The rigorous training not only honed his body but also his mind, though that improvement was less immediately obvious. The body, soul, and mind always work together, and Ethan knew he was still far from being able to extract energy from every cell rapidly.
Step by step, his Chakra increased—from 0.1 card, to 0.2, then 0.5, 1 card, and finally reaching 1.5 cards. At that point, he paused his refining, satisfied that his Chakra refining technique was perfected.
[Uchiha Chakra Refining Technique (29851/100,000, perfect)]
Blessed with natural talent and a deep understanding of the technique, his progress had been remarkably swift. The method itself was simple, and he mused, "It looks like it will only take a few days to reach perfection and then break through my current limits!"
Curiosity filled his thoughts. "I wonder what new skills might emerge once this Chakra refining technique breaks its limit. Will I be able to cultivate immortality directly? Or perhaps develop an even sharper version of Chakra refining?"
Studying his panel information intently, he reasoned, "Hmm, immortal cultivation seems unlikely—the leap is too vast. Chakra refining doesn't involve absorbing natural energy. Perhaps if the immortal art practice method eventually breaks through, it might be sublimated into something like Sage Art."
Ethan recalled hints of the immortal art practice method mentioned in the Wet Bone Forest. Now that he was Tsunade's apprentice, he planned to ask for Katsuyu's Summoning contract qualification later—and maybe even learn from Katsuyu Sage when the time was right. In his heart, he hoped to create an immortal art or cultivation method suited for humans, rather than relying on half-baked, demon cultivation methods with hidden dangers. After all, he'd seen how abnormal Mount Myōboku's immortal art could become.
"Next is Chakra control training!" Ethan declared, pushing aside his swirling thoughts. He left his room and headed to a large tree near the small training ground in the backyard.
Standing at the base of the tree, he gathered a certain amount of Chakra under his feet. With focused intent, he stepped toward the tree trunk.
"Crack!"
The bark shattered beneath him—clearly, he had used too much Chakra at once. Reacting quickly, he reduced his output and tried again. This time, he succeeded. As he steadied himself, a new skill flashed onto his attribute panel:
[Chakra Control (1/100), entry level.]
The moment the skill manifested, insights flooded into his mind. Having grown accustomed to such bursts of understanding, he quickly digested the information.
Taking another step forward, Ethan placed both feet firmly on the tree trunk and began climbing.
[You have conducted Chakra control training, Chakra control proficiency +3.]
[You have conducted Chakra control training, Chakra control proficiency +3.]
[You have conducted Chakra control training, Chakra control proficiency +4.]
Before long, he reached the top. His control over Chakra had improved dramatically—climbing was now effortless, and his proficiency in Chakra control had reached a commendable level.
"I have improved so fast! This is my true talent and understanding," he thought with exhilaration. "In the past, my congenital deficiency held me back, but not anymore!"
Ethan became increasingly absorbed in his practice. Unlike before, when each Chakra extraction was done with trembling caution and fear of self-injury, he now moved with confident precision. Before awakening the memory and talent of his previous life, his understanding and mental strength were weak. Only after those memories and the combined force of two lives emerged did he truly begin to excel—a truth verified long ago.
Now, standing atop the tree, Ethan gazed out over the entire Uchiha clan territory and the dimly lit spires of Konoha in the distance. A surge of determination filled him. His journey to become a truly formidable ninja had only just begun.
