Feeling the intense waves of chakra fluctuations.
Guren was completely numb by now.
"Forget it, why even care? This brat is simply not a normal person."
"No wonder Orochimaru-sama said he is the perfect vessel."
"Just this terrifying talent alone is unmatched in the entire ninja world."
What's more, he possesses the bloodline of the Uchiha clan and has successfully awakened the Mangekyō Sharingan.
For a monster like this, there is no comparison to be made.
But what puzzled Guren now was Sasuke's current state.
It seemed like he was repeatedly activating the curse mark mode.
And as the frequency increased, Sasuke's transitions into curse mark mode seemed to become incredibly smooth.
The strangest part was that Sasuke's curse mark mode seemed to grow increasingly terrifying.
The chakra fluctuations he emitted became stronger and stronger.
From day to night, Sasuke didn't open his eyes once.
[Special Status: Curse Mark of Heaven (73% Released)] ↑2%
...
[Special Status: Curse Mark of Heaven (76% Released)] ↑3%
...
[Special Status: Curse Mark of Heaven (81% Released)] ↑5%
...
[Special Status: Curse Mark of Heaven (87% Released)] ↑6%
Each time Sasuke completed a training session with the Curse Mark of Heaven,
The percentage of release increased at an insane rate.
Not only did the speed of growth not slow down, but it seemed to accelerate instead.
Being able to feel these changes in real-time was already addictive.
Let alone this frenzied progress.
It was utterly irresistible.
Even the feeling of hunger couldn't make Sasuke stop.
He was in an extremely exhilarated state.
Two entire days of non-stop training.
By noon,
Sasuke finally opened his eyes slowly. The commotion caused by his final session startled both Guren and Haku.
An invisible vortex formed out of thin air, hovering above Sasuke's head.
It was as if some kind of special energy from all directions was crazily pouring into Sasuke's body.
At this moment, Sasuke's body transitioned into a special state that even Orochimaru hadn't foreseen.
Curse Mark Stage Three!
Initially, when Sasuke entered Curse Mark Stage Two, he thought it was the limit of the Curse Mark of Heaven.
The only remaining possibility was to strengthen the power of Stage Two.
However, Sasuke didn't expect that after fully mastering the Curse Mark of Heaven,
There was actually a Stage Three form.
A pair of large hands resembling wings grew from Sasuke's back.
Similar in appearance to those from the original design, but in Curse Mark Stage Three,
Black markings, reminiscent of Stage One, reappeared on Sasuke's arms.
They spread across his arms and even covered the dragon-like structures on his back.
It looked utterly bizarre.
A living embodiment of a demonic figure.
However, Sasuke didn't care about his outward appearance in this state. What mattered to him was the change in chakra.
The chakra seemed to have fused with a massive amount of spiritual energy.
Its color turned black.
Not completely pitch black, but glowing with a black sheen.
Even techniques like Chidori would take on a black hue, and even flames bore a faint black light in this state.
His chakra reserves increased by five or six times, and all of it transformed into curse mark chakra.
The aura Sasuke emitted in this state immediately made Guren and Haku's hearts tighten.
This was because Sasuke's chakra seemed to carry some terrifying mental impact.
It made them afraid to even look directly at him.
"What an eerie chakra fluctuation. Just feeling it makes me feel like I'm going to die."
"It's like being stared down by some terrifying beast."
Guren silently swallowed her saliva.
Haku's inner feelings were similar.
However, Sasuke's state came and went quickly.
When the Curse Mark of Heaven reached 100% release, the system displayed a new notification.
[Special Status: Curse Mark of Heaven (100% Released)]
[Congratulations to the host for obtaining the special constitution: Sage Transformation]
[Special Constitution: Sage Transformation (Beginner Level)]
What?!
Sasuke was stunned.
"So mastering the Curse Mark completely can even grant a special constitution?"
"Sage Transformation? Is it similar to Sage Mode?"
This was an unexpected surprise!
But thinking it over carefully,
The so-called curse mark was essentially a method Orochimaru developed based on Jūgo's unique constitution.
It was just a tool for Orochimaru to make it easier to take over others' bodies.
If the curse mark could be perfectly mastered without its erosion, obtaining the same special Sage Transformation constitution as Jūgo wouldn't be strange at all.
Still, even Orochimaru likely never imagined that someone could perfectly synchronize with and master the curse mark without being consumed by it!
How could such a thing be possible?
Even Jūgo himself wouldn't claim to have perfectly synchronized with Sage Transformation.
After all, whenever Jūgo entered his Sage Transformation state, he would lose control and go berserk.
But Sasuke, with his incredible talent and possibly his exceptional physical constitution,
Managed to master the curse mark flawlessly.
"So now... I have essentially gained a unique Sage Mode."
"Even better, in my Sage Transformation state, I don't need to consciously absorb and generate Sage Chakra."
"My body can do it automatically for me."
"And with the added effects of Wood Release, the speed of producing Sage Chakra will be even faster!"
Sasuke's eyes gleamed with excitement.
If he'd known the Curse Mark of Heaven concealed such a surprise, he would have worked tirelessly to bring it to 100% long ago.
Why wait until now?
"From now on, I need to dedicate all my time to training every technique."
What if mastering certain jutsu to a high enough level also brings unexpected rewards?
After achieving 100% mastery of the curse mark and gaining the special Sage Transformation constitution,
The most immediate change was that Sasuke no longer needed to exert control over his Curse Mark Stage Three form.
This form seemed to fully activate the complete Sage Transformation state.
In other words, Sasuke could now enter Curse Mark mode and use techniques like Thunder Breathing without any strain.
Unlike before, where he had to carefully maintain the curse mark's activation while controlling his chakra just to use Thunder Breathing.
"'Lord Sasuke, are you there?'"
"'I am Kabuto Yakushi. At Orochimaru-sama's orders, I have come specifically to assist Lord Sasuke.'"
Kabuto's voice echoed from outside the cave.
Sasuke stood up slowly.
Perfect timing... now he was fully ready to proceed with sealing the Three-Tails!
