Chapter 610: Perfection  

The ambush by Mist Ninjas that Seimei had worried about never happened, and his group returned to camp without any issues.  
After reporting the mission to the task office personnel, Seimei dismissed the team and went to train on his own.  

 Since it was still early in the day, he didn’t stay at the camp for long. Leaving behind a shadow clone, he flew away.  

 Seimei wasn’t worried about causing trouble. With his current level of spiritual power, his mastery of the “Mind Link Technique” allowed him to stay connected to his shadow clone over distances exceeding 100 kilometers.  

 This meant that as long as he remained within this range, he could always be informed of anything happening at the camp.  

 Moreover, with his **Lv7 (0/0) Perfect-Level** "Wind Release: Wings of Wind," it would take him no more than six minutes to return.  

 Not to mention, he wouldn’t stray 100 kilometers away in the first place. If the distance was halved, he could return to camp in just two or three minutes.  

 During this time, even if something happened, his shadow clone could hold the fort until he returned.  

 This was why Seimei dared to leave camp.  

 For the same reason, Nara Kigami allowed him to venture out frequently.  

 Seimei didn’t think that the numerous Byakugan users in the camp would fail to notice that his real body wasn’t there.  

 Indeed, while Byakugan couldn’t distinguish between a shadow clone and the original, the difference in chakra levels was obvious.  

 Thus, it wasn’t hard to deduce that the one in the camp was just a shadow clone.  

 And yet, Nara Kigami had never caused him any trouble over this. If that wasn’t tacit approval, what was it?  

 Various thoughts flashed through his mind as Seimei flapped his wings and flew rapidly toward his usual training spot.  

 As the sharp wind lashed against him like blades, Seimei formed a hand seal and skillfully cast the ninjutsu—**Chakra Cloak**!  

 *Swish~*  
A faint azure glow enveloped him.  

 Suddenly, a chakra-formed cloak appeared around his body.  

 The razor-sharp winds could only cause minor ripples on the cloak’s surface and couldn’t affect him at all.  

 And this was just one of the minor benefits of the **Chakra Cloak.**  

 The current cloak looked much more realistic than before. Were it not for the characteristic chakra glow, it could almost pass as actual clothing.  

 The reason for this improvement was simple: just yesterday, after over 20 days of practice, his **Chakra Cloak** had finally leveled up.  

 Now at **Lv8**, though not yet at the theoretical max of **Lv9**, its effectiveness had significantly increased.  

 Realism was one aspect, but its greatest improvement lay in its resistance to ninjutsu-based attacks.  

 When Seimei activated his **Chakra Cloak**, it could now block most ninjutsu below **C-Rank**, except for particularly strong fire release techniques.  

 Additionally, after leveling up to **Lv8**, the cloak gained a new trait: **Self-Regeneration.**  

 As long as Seimei had sufficient chakra, and the enemy’s attacks didn’t instantly surpass its defensive limit, the cloak could recover in a short time with chakra supply.  

 Seimei had tested it with his shadow clones. Unless he faced more than ten consecutive **D-Rank** ninjutsu attacks within a single second, his defenses wouldn’t be breached.  

 For **C-Rank** attacks, the limit was two hits within one second. As long as he wasn’t hit twice in rapid succession, the **Chakra Cloak** would ensure his safety.  

 As for **B-Rank** attacks, Seimei hadn’t tested them on himself. But when his shadow clone endured a single hit, it shattered instantly.  

 Thus, tanking a **B-Rank** attack seemed to be its current limit, though he would likely sustain injuries.  

 However, this was only the technique’s current stage.  

 Once the **Chakra Cloak** leveled up to **Lv9**, its qualities would undergo another transformation. At that point, it could likely withstand a **B-Rank** attack entirely, or even multiple hits.  

 And this was still just an ordinary chakra cloak.  

 If Seimei ever mastered Sage Mode and infused the cloak with senjutsu chakra, he could potentially develop a specialized defensive sage technique.  

 By then, not only **B-Rank** but even **A-Rank** and **S-Rank** ninjutsu might be manageable.  

 That said, this technique remained his last line of defense.  

 Given his current growth rate, it was nearly impossible for an enemy to hit him repeatedly in a short span, let alone maximize their ninjutsu’s impact.  

 In theory, he could withstand numerous attacks.  

 If he managed his rhythm well, the **Chakra Cloak** might not even be broken before his chakra was depleted.  

 As Seimei’s thoughts wandered, he arrived at his destination.  

 This was a secluded forest about 50 kilometers from the battlefield near Yutsutsu Port.  

 Flying back to camp from here would only take about three minutes.  

 Seimei formed a hand seal to release the **Guardian Seal** on his forehead. After activating his Byakugan, he flew around the area.  

 After confirming no one was nearby, he landed on the ground.  

 Wasting no time, he cast the **Shadow Clone Technique** and created nearly 20 clones to begin his planned training.  

 ...  

 Nightfall  
As the sun set and the moon rose, the hours passed swiftly.  

 By the campfire, Seimei sat cross-legged, repeatedly practicing **Palm Sage Technique** and **Heart Reflection Technique** to enhance his body and guide his Sharingan’s evolution.  

 Previously, he would’ve returned to camp to complete these training sessions.  

 But tonight, he stayed longer, and for a good reason:  

 His **Rasengan** was about to level up!  

 He had estimated that this technique would reach the next level either tonight or by tomorrow at the latest.  

 To ensure it would be ready for tomorrow’s mission, Seimei allocated extra chakra to practicing the technique.  

 Around him, several shadow clones were still diligently training with **Rasengan.**  

 Suddenly, Seimei opened his eyes.  

 Surveying the shadow clones still practicing in the forest, he murmured, “It’s about time,” and dispelled the **Shadow Clone Technique.**  

 *Boom~*  
As chakra smoke bursts filled the air, all the clones vanished.  

 Simultaneously, a surge of training memories flooded Seimei’s mind.  

 He focused intently, quickly processing the accumulated experiences and converting them into skill proficiency on his mental panel.  

 Since all the clones had been practicing **Rasengan**, the process was far simpler and faster than handling diverse experiences.  

 Within minutes, he opened his eyes again, a gleam of understanding flashing within them.  

 Raising his right hand, Seimei concentrated, and a pale blue chakra sphere materialized in his palm.  

 The sphere spun quietly, showing no outward signs of menace.  

 Compared to **Lv8**, his perfected **Lv9 (0/0)** Rasengan had seen improvements in both speed of formation and stealth.  

 Previously, he needed to create or wait for the perfect opportunity to use it effectively.  

 Now, its deployment conditions were much less restrictive, and the results were no less devastating.  

 This was just one of its advantages.  

 Additionally, the perfected **Rasengan** made learning the **Wind Release: Rasenshuriken** significantly easier.
