Thanks to a deliberate effort to harvest chakra during the subsequent pursuit, Seimei managed to gather a substantial amount of chakra.
As a result, despite consuming a significant amount of chakra in today's battle, the overall amount available for his training not only remained unaffected but even increased. This newfound surplus allowed him to create more shadow clones, enabling them to shoulder greater losses and compensate for any deficiencies in training time.
Thus, he completed his scheduled training plan for the day on time.
After this day, the entire eastern front of Konoha entered a period of calm. Even though a few scattered Mist Shinobi remnants remained, they caused no further trouble.
Both sides shifted their focus to the latest negotiations.
Three days passed quickly.
While the negotiations yielded no results, Seimei's training saw remarkable progress.
Afternoon
In a remote forest, Seimei dissolved his "Multi Shadow Clone Jutsu," recalling all his clones to absorb and digest the experience and memories they accumulated over the past hour.
A surge of complex information flooded his mind. Closing his eyes, he meticulously processed and organized the data, converting it into skill proficiency.
Time passed slowly.
About a quarter-hour later, Seimei opened his eyes, and a flicker of joy flashed in his gaze.
Instead of immediately summoning more shadow clones to continue training, he walked to the area where his clones had practiced the "Wind Style: Rasenshuriken."
The forest, once lush, now lay in shambles due to the intense training. Trees were broken at their midsections, their cross-sections smooth and curved, clear evidence of being struck by the "Wind Style: Rasenshuriken." The ground was riddled with craters, further testament to the training.
Seimei surveyed the destruction with only a passing glance before focusing on a low hill in the distance. Raising his right hand, he gathered chakra and executed the S-Rank forbidden jutsu—**"Wind Style: Rasenshuriken!"**
Zzzzz~
A piercing sound filled the air as the surrounding atmosphere was stirred and torn apart. A massive, menacing chakra shuriken appeared above Seimei's palm, spinning rapidly. It was entirely composed of tangible chakra, suspended a few centimeters above his hand.
Pausing briefly to sense the shuriken's state, Seimei nodded in satisfaction before hurling it toward the distant hill.
As he had suspected, while the "Wind Style: Rasenshuriken" required mastery for ranged attacks, absolute perfection was unnecessary.
For Seimei, achieving proficiency Level 9 was sufficient. By chance, his clones' training had just raised his skill to this level, so he was eager to test its effectiveness.
A dull explosion echoed in the distance. Seimei observed the low hill, which now appeared as though a giant bite had been taken out of it. The missing section matched the smooth cuts seen on the trees.
The Rasenshuriken had carved a straight path of destruction between Seimei and the hill, annihilating everything in its trajectory—trees, rocks, soil, and all.
The power of this technique clearly surpassed ordinary A-Rank jutsu.
What excited Seimei most was that this wasn't even its full potential. If he pushed his chakra output to the limit, the power would undoubtedly reach a new height.
However, there was a limitation. While Seimei could now throw the Rasenshuriken, he couldn't yet control its trajectory mid-flight. Unlike Naruto in later stages, he couldn't make it turn or maneuver.
This linear attack posed a significant drawback. An alert enemy could maintain distance or react quickly to dodge the attack.
Although Seimei's Sharingan granted him predictive abilities, it wasn't foolproof. Such a powerful technique, if used without decisive results, would lose its strategic value.
Encouraging himself, Seimei reviewed the skill panel. But when he saw the proficiency points required to upgrade "Wind Style: Rasenshuriken" from Level 9 to Level 10, his face froze.
A whopping 100,000 proficiency points were required!
Even Seimei couldn't help but gasp at the staggering number.
Fortunately, he quickly calmed down. While the requirement was immense, it wasn't insurmountable. Thanks to his mastery of "Rasengan" and other Wind Style jutsu, his training efficiency for the Rasenshuriken had significantly improved.
On average, 100 chakra points equated to 1 proficiency point. At his current training intensity, he estimated it would take around 62 days—just two months—to reach Level 10.
Although not short, it was manageable. Seimei had the patience to see it through. Once the skill reached Level 10, he would likely gain the ability to manipulate the shuriken mid-flight, a massive boost to his combat power.
After a moment of thought, Seimei glanced at the near-maxed "Guardian Seal" skill on his panel before closing it. Without wasting any time, he returned to his previous training area and cast the "Multi Shadow Clone Jutsu" once more, summoning eight clones.
He assigned them new training tasks and sent them off, while he himself continued practicing the "Palm Sage Jutsu" and "Mind Reflection Technique."
After all, physical and mental strength formed the foundation of everything, and he could not afford even the slightest neglect.
Once again, the forest fell silent.
