A few hours passed in the blink of an eye.
Before long, evening had arrived.
Beneath Moon Island.
Inside the volcano.
As usual, Seimei was strengthening his body.
When another surge of sage chakra was guided into the Byakugan in his forehead, a strange sensation washed over him.
Instinctively, Seimei activated his Byakugan.
In the next moment, everything within a three-kilometer radius came into view.
Seimei carefully observed his surroundings, noticing that the Byakugan's precision and perspective abilities had improved slightly.
But that wasn't all.
With a single thought, Seimei halted his training in the "Limit of the Body" technique. In a flash, he appeared at the edge of the circular platform.
Gazing down at the roiling magma below, he focused his mind, channeling chakra to activate the Byakugan in his forehead.
In an instant, a gravitational force was unleashed.
A stream of magma was drawn upward, slowly rising and forming a small magma sphere in midair.
More magma was continuously pulled from below, merging into the sphere, causing it to grow larger and larger.
Finally, when the sphere reached a diameter of twenty meters, the flow of magma from below stopped.
Seimei had reached the limit of his control.
Looking at the magma sphere hovering in front of him, Seimei estimated its weight.
Under normal conditions, magma's density ranges between 2.3 and 3.0 grams per cubic centimeter. Based on this, the sphere before him weighed approximately ten thousand tons.
In other words, his Byakugan could now manipulate a gravitational force equivalent to ten thousand tons.
This was ten times greater than before.
Clearly, his Byakugan's evolution had broken through the (10,000/100,000) threshold; otherwise, such a massive improvement would've been impossible.
While Seimei was slightly surprised by this leap, after a moment's thought, it made sense.
After all, in its complete form, the Tenseigan, when sufficiently powered, could manipulate entire planets.
Compared to the weight of a planet, ten thousand tons was insignificant.
So, after a brief moment of surprise, Seimei quickly regained his composure.
Feeling the rapid depletion of his chakra, he thought to himself, *"Looks like this comes at a cost."*
At his current chakra consumption rate, even if he gave this Byakugan to someone else, they wouldn't be able to handle it.
No wonder no one in the Hyuga clan had ever pushed the Byakugan to this level. The principle was simple: you can only control as much power as your ability allows. That's an unchanging truth.
With various thoughts swirling in his mind, Seimei released his control over the magma sphere.
In an instant, the sphere plummeted, crashing into the magma lake below.
A massive splash of magma erupted, sending streams of molten rock shooting in all directions.
Some of the magma hurtled straight toward Seimei.
Truth be told, with his current recovery abilities and the "Chakra Cloak," even if the magma hit him, he wouldn't sustain much damage. A little chakra would be enough to heal.
But he wasn't keen on enduring that pain.
With a thought, he activated the Byakugan in his forehead again, releasing a repulsive force.
In the next moment, the incoming magma streams seemed to hit an invisible barrier, halting in midair and forming a spherical arc that enveloped Seimei.
Then, they were flung back, crashing into the magma lake below.
More streams of magma were stirred up, but this time, they couldn't reach Seimei on the platform.
Ignoring them, Seimei stepped back to the center of the platform and closed his eyes, focusing on the surging mental energy within him.
As expected, when his Byakugan's evolution broke through the (10,000/100,000) threshold, his "mental" attribute had indeed increased by one point, from 36 to 37.
Correspondingly, his mental energy had skyrocketed.
Seimei was now working to rein in this overwhelming surge of mental power.
---
Time ticked by, second by second.
About ten minutes later, Seimei opened his eyes.
A faint wave of mental pressure flickered around him before vanishing.
In that moment, the uncontrolled mental energy retreated into his mind, fully under his control.
With that, the slight side effects of the Byakugan's breakthrough were resolved.
Next, it was time to test the additional benefits brought by the increase in his "mental" attribute.
With this in mind, Seimei checked the time. Exactly one hour had passed.
Wasting no time, he used the "Flying Thunder God Technique" to teleport back to Moon Island.
His vision shifted abruptly.
Standing in the open area at the center of Moon Island, Seimei took a deep breath of the fresh air around him.
Then, he exhaled slowly.
After lingering for a moment, allowing his body to heal from the damage sustained in the harsh volcanic environment below, he dispelled the "Multiple Shadow Clone Technique."
Instantly, all his shadow clones, both on and off the island, dissipated.
A flood of memories rushed into his mind.
Seimei spent about fifteen minutes sorting through these memories, absorbing and digesting the training experiences they contained.
Once that was done, he began testing the gains from this "mental" attribute increase.
First, he focused on the theoretical chakra limit increase.
He furiously activated the "Chakra Refining Technique," tapping into his potential and comparing the changes in his body to estimate the growth in his potential.
Just like last time, thanks to the advancement of his "Chakra Refining Technique," this step took only about ten minutes.
In the end, he concluded that this "mental" attribute increase had boosted his potential—his theoretical chakra limit—by roughly six million points.
While this was far less than the sixteen million points he gained yesterday when his "physical" attribute rose from 35 to 36, it was understandable. Yesterday's "physical" attribute increase had restored balance between his mind and body, unlocking more potential. Additionally, the "mental" attribute typically didn't contribute as much to potential growth. So, Seimei accepted it.
Besides, for him now, the theoretical chakra limit wasn't the priority. What mattered more was the increase in chakra recovery speed.
With this thought, Seimei calmed his mind. After a brief pause, he stopped the "Chakra Refining Technique."
Then, he opened his panel, quietly observing the changes in his "Chakra" while letting his body naturally recover chakra.
Time passed, minute by minute.
Ten minutes later, he stopped observing.
At that moment, his panel showed an increase of 381,250 chakra points.
Recovering 381,250 points in ten minutes meant 2,287,500 points per hour, and 54,900,000 points in a full twenty-four-hour day.
In other words, with sufficient energy, his body could now naturally recover 54.9 million usable chakra points per day.
Yesterday, that number was only 51.4 million.
This meant the "mental" attribute increase had boosted his chakra recovery speed by 3.5 million points.
Compared to his last "mental" attribute increase, this was 700,000 points more. It wasn't a huge leap, but it was decent, and Seimei could live with it.
As a result, his daily surplus chakra would rise from 13.368 million points to 16.868 million points.
Of course, this was assuming he didn't adjust his training plan.
But clearly, that wasn't going to happen.
Now that his base attributes had reached a new milestone, it was time to tweak his training regimen.
