With that thought, Seimei closed his proficiency panel, formed hand signs, and cast the Multiple Shadow Clone Technique.
Poof! Poof! Poof!
As clouds of chakra smoke dispersed, 800 shadow clones appeared in the field.
As usual, Seimei assigned 300 clones to absorb natural energy, while the remaining 500 focused on blending the seven chakra nature transformations, working toward developing the power of the Bloodline Network.
Soon, all the clones dispersed to their tasks.
Then, Seimei used the Flying Thunder God Technique to teleport straight to the volcano beneath Moon Island.
Faced with the familiar, harsh environment, he took a moment to adjust before drawing on the natural energy stored in his abdominal sealing space and entering Sage Mode.
Next, he went all out, repeatedly activating Limit of the Body to strengthen his physique.
Of course, he made sure to keep a close eye on his Byakugan, ensuring its evolution didn't progress alongside his body.
Time ticked by, second by second.
Before he knew it, it was late at night.
Seimei finished his final round of training and paused all his actions.
Only then did he take a moment to check the results of the day's tests.
As expected, after this latest transformation, his body's resilience had noticeably improved.
Now, maintaining peak training efficiency required a total of 43 million chakra points.
Before, he'd only needed 35 million points for physical enhancement.
That meant his chakra consumption had jumped by 8 million points.
Clearly, the 6-million-point chakra boost from his physical attribute increase wasn't enough to cover it.
He'd need to dip into his daily surplus of 9.52 million chakra points, pulling out an extra 2 million to make up the difference.
But with such a hefty investment came equally hefty rewards.
Based on Seimei's initial tests, his body's enhancement speed had increased by about 20% compared to before the transformation.
At this rate, it wouldn't take long for his body to reach the next transformation threshold.
Especially since he'd paused his Byakugan's evolution, which already boosted his physical enhancement speed even further.
That said, to pin down an exact timeline for the next transformation, he'd need to train a bit longer and gauge the changes in his body for a more accurate estimate.
For now, though… no rush!
After mulling over these thoughts, Seimei stood up, walked to the wooden cabin nearby, washed up briefly, and went inside to rest.
The night passed quietly.

The next day.
Seimei woke up early.
Just like the day before, he dove into a new day of training.
This session lasted two full days.
After those two days, his ten-day intensive training period came to an end.
Seimei returned to the Hidden Leaf Village, taking a day to rest and recover.
Then, he headed back to Moon Island and resumed training.
This time, he trained for another five days.
After a total of eight days of intense enhancement, his body showed noticeable changes.
Based on these changes, Seimei estimated the time needed for his next transformation.
As he'd predicted, it wouldn't take too long.
He roughly calculated that in about five months—around early February next year—his body would hit the transformation threshold.
That might seem longer than last time, but considering that each transformation raised the difficulty of the next, this was already a fast pace.
Seimei was pretty satisfied with that.
And that wasn't even the final timeline.
Based on his earlier estimates, in two to three months, his Ice Release and Storm Release would advance. A month after that, his Lava Release would follow suit.
When that happened, his body's potential would improve further, shortening the timeline even more.
So, Seimei was confident his body would reach the transformation threshold within five months.
But whether it took five months or less, that was a problem for later.
For now, he'd focus on training.
With that in mind, Seimei returned to the wooden cabin, rested for the night, and started training again the next day.
Days passed one after another.
In the blink of an eye, six days had gone by.
It was noon.
Seimei was still in the volcano, training with Limit of the Body.
Suddenly, a jolt ran through his mind, and a wave of insight flooded in.
He quickly stopped, exited Sage Mode, and cast Flying Thunder God Technique to teleport back to Moon Island.
Sitting cross-legged, he closed his eyes and began processing the insight.
Time slipped by, second by second.
About half an hour later, he opened his eyes again.
They were gleaming with excitement.
With a thought, he opened his proficiency panel.
There, his Chakra Refinement Technique had jumped from Level 7 to Level 8 (1/50,000)!
That burst of insight had come from the level-up.
And the payoff?
Sure, going from Level 7 to Level 8 wasn't a qualitative leap like Level 4 to 5 or Level 6 to 7, but it was still a high-level advancement, so the changes were significant.
Seimei closed his eyes and tried running the new Chakra Refinement Technique.
It went smoothly, with no hiccups.
After a few minutes of getting the hang of it, he set it to run passively.
Then, he waited quietly.
About ten minutes later, he turned his attention back to the panel.
In those ten minutes, beyond the 301,389 chakra points his body naturally recovered, he'd gained an extra 1,167 points.
Those extra points came from the passive Chakra Refinement Technique.
Ten minutes at 1,167 points meant about 7,000 points per hour.
Before, it was 5,000 points per hour.
So, this level-up boosted his hourly chakra recovery by 2,000 points. Over a 24-hour day, that added up to 48,000 extra chakra points.
It wasn't a ton, but as the saying goes, even a mosquito's leg is still meat—Seimei wasn't complaining.
Plus, that wasn't the main benefit. The real prize was the boost to his potential-digging speed.
At Level 7, an hour of running Chakra Refinement Technique increased his chakra ceiling by 300 points. Now…
He glanced at the "Chakra" section on his panel. In those ten minutes, his chakra ceiling had risen by 167 points.
That worked out to 1,000 points per hour—over three times the previous rate.
While the proportional increase wasn't as dramatic as the fivefold jump from Level 6 to 7's qualitative leap, the absolute value was far greater.
And that was the big win this time.
With Level 8 Chakra Refinement Technique, his ability to tap into his potential would skyrocket, and his chakra ceiling would climb faster than ever.
Seimei was thrilled at the prospect.
