Just as Takuno was about to take the meteorite, he paused.
Then, he rubbed his forehead with his hand, as if to relieve a headache.
This wasn't due to any illness, but rather the result of a Shadow Clone, which was responsible for experimenting with the Chimera Technique to fuse a second body, dissipating, causing a flood of experimental memories to rush into his mind.
He had specifically 'instructed' the Shadow Clone not to experiment for too long; otherwise, the excessive memory transfer could have overwhelmed him instantly.
Therefore, Shadow Clones usually self-dissipate after a period of experimentation.
Takuno briefly organized his memories, then formed a hand seal again and created another Shadow Clone, which walked into the laboratory without hesitation.
He watched the Shadow Clone's figure; of course, he hadn't only created one Shadow Clone, as his other two Shadow Clones were practicing Ninjutsu.
Practicing Ninjutsu was much better than experimenting, as most of it involved repetitive labor with few memory points, so even if they dissipated, it wouldn't affect him much, unless it was like Naruto with hundreds of Shadow Clones at once... After the Shadow Clone disappeared, Takuno also sighed. His current strength still didn't allow for any relaxation; he needed to practice Ninjutsu, learn knowledge, and research too many things.
Compared to before he obtained the Chimera Technique, he was much more tired, truly... a happy burden.
Having clear goals to pursue and concrete tasks to do, even if tiring, as long as there are results, it's always joyful!
As the main body, he wasn't idle either. He took the meteorite from the cultivation chamber, thought for a while, then sat cross-legged, placing the meteorite in his hands, and began to absorb the meteorite's vitality to form Star Chakra.
If the people of Hoshigakure saw this method, they would probably be dumbfounded.
They wouldn't dare to train with the stars in this way; it could be said that even Natsuhi, a talented Jonin, would likely be infected and killed by the meteorite's vitality before completing her training if she tried this.
Takuno, however, chose to endure it with his Uzumaki bloodline.
And the speed of this training was naturally extremely fast... Several days later.
Takuno felt the Chakra within his body; he hadn't fully completed his training, but he had already made some progress.
At this moment, a Rasengan once again condensed in his hand, but this Rasengan seemed different from a normal one, as a hint of purple suffused it.
Without hesitation, he pressed the Rasengan against the earth wall.
Instantly, the point where the Rasengan touched the earth wall erupted in a brilliant light, with white light mixed with purple.
When everything ceased, a huge crater appeared on the earth wall.
Takuno examined the crater and nodded. The power had increased by about two to three tenths, and this was before he had completed his cultivation. If the Chakra activation was fully completed, the power could probably increase by about five tenths.
Although this increase wasn't as great as Tailed Beast Chakra, it was already powerful enough.
This experiment wasn't over yet. Intense Chakra fluctuations once again condensed in Takuno's palm, seemingly forming another Rasengan.
But soon, the piercing sound and the shuriken-like appearance made everyone realize that this was not a Rasengan, but... Wind Release: Rasengan!
The Wind Release: Rasengan was not as perfectly round as a Rasengan, nor as massive as a Wind Release: Rasenshuriken; its size was only slightly larger than a normal shuriken.
This was the achievement of the Shadow Clone that had been practicing Ninjutsu during this time! He had successfully mastered Wind Release: Rasengan!
Wind Release: Rasengan was arguably not far from Wind Release: Rasenshuriken; he only needed to increase the Chakra output and continue to stabilize the Chakra.
But the problem was that stabilizing a massive amount of Chakra wasn't easy. If the Chakra amount was easily increased without stabilization, it would be like Naruto's half-finished product, requiring close-range release of the Wind Release: Rasenshuriken.
The result would be harming the enemy ten thousand while damaging oneself eight thousand. If Takuno wanted to use Wind Release: Rasenshuriken without Sage Mode, he could only deepen the stability of the Wind Release: Rasenshuriken, needing to practice it to a perfect degree where he could throw the Wind Release: Rasenshuriken without worry.
Takuno dispelled the Wind Release: Rasengan. Although its after-effects were far less severe than the Wind Release: Rasenshuriken and could recover, there was still a slight impact.
Therefore, it was generally better to let a Shadow Clone use this technique.
As for why Wind Release: Rasenshuriken couldn't be used by a Shadow Clone?
That's because his Shadow Clones didn't have that much Chakra; even Wind Release: Rasengan consumed a significant amount, let alone the consumption of Wind Release: Rasenshuriken.
Even the current Takuno, exerting all his strength, could probably only use Wind Release: Rasenshuriken two to three times, and this was a result of him possessing the Uzumaki bloodline.
If Takuno wanted a Shadow Clone to use Wind Release: Rasenshuriken, he would probably have to learn from Naruto and use his main body's Chakra to help the Shadow Clone create the Wind Release: Rasenshuriken... Like Naruto, who was very fatigued after using Wind Release: Rasenshuriken three times against Kakuzu, though his condition wasn't very good at the time.
Naruto in Sage Mode could use Sage Art: Rasenshuriken twice, but that was due to the duration of Sage Mode.
If combined with Naruto's fatigue after using Big Ball Rasengan, it could be inferred that the number of times he could condense it at full strength outside of Sage Mode would probably not exceed ten.
Of course, this doesn't include the times with Nine-Tails Chakra, but Naruto's own Chakra reserves are incomparable to ordinary people.
It's clear that even if a specific learning plan was provided for this technique, probably few people would learn it.
The sheer amount of Chakra required alone filters out most potential users.
"I still need to continue increasing my Chakra reserves," Takuno murmured.
Now that he had the Uzumaki bloodline, it would probably be very difficult to further increase his Chakra through other Kekkei Genkai; even if he could increase some, the total amount wouldn't increase much.
Therefore, he could only resort to another method, which was — physical conditioning.
He had tried practicing Taijutsu before, but gave up due to a lack of physical talent. Now with the Uzumaki bloodline, he could start using Might Guy's training methods, though the initial intensity couldn't be that high.
And physical conditioning couldn't be left to a Shadow Clone, as a Shadow Clone would only transmit fatigue and learning experience to him, making him feel sensory fatigue, while physical conditioning actually requires repeated physical training; learning experience is useless for it!
Therefore, there are almost no shortcuts for physical conditioning.
Thinking of this, Takuno couldn't help but rub his temples again, feeling a bit of a headache.
Things just got even more numerous!
