However, that was because his control over Cursed Energy was still too crude!
A vast majority of the Cursed Energy was wasted due to uneven output and imprecise control.
If he could increase the maximum output capability of that Cursed Energy and perform precise control over this power, injecting it into his optic nerves without wasting a single bit, perhaps…
He could still strike while the iron was hot to make one more breakthrough, instantly reaching the Three-Tomoe Sharingan!
As for how to forcibly increase Cursed Energy output and precise control in such a short amount of time?
“Hehe, come on! It’s time to show off a real technique!”
The corners of Shu’s mouth lifted into a smile.
“Loans, let me see the limits of your capabilities!”
“I, Uchiha Shu, at the price of permanently forfeiting my Innate Technique, exchange it for an enhancement in the precision of my Cursed Energy control and my own Cursed Energy output capability!”
That’s right!
This was the most bug-like special power system in the perspective of the Jujutsu Kaisen world: the Binding Vow!
In that world, individuals possessing the Cursed Energy power system—whether Jujutsu Sorcerers, Curse Users, or Cursed Spirits—could all apply specific Binding Vows upon themselves.
By intentionally restricting certain abilities or paying a specific price, they could exchange that for an increase in ability in other aspects.
The most classic example is the Innate Technique Disclosure:
In battle, by revealing information regarding one’s own technique abilities and weaknesses to the enemy as a price, one forms a Binding Vow to exchange it for a drastic increase in power for the next strike of that technique.
Although in the latter part of the original storyline, humorous situations arose surrounding these Binding Vow settings.
Especially Sukuna, dubbed the King of Curses; he even relied on many Binding Vows that appeared cheaply priced—even somewhat ridiculous—to others, to exchange for huge tactical advantages, winning one fight after another while in desperate positions, leading many to shout that the balance mechanism of Binding Vows in Jujutsu was truly pathetic.
Although it was indeed quite pathetic, there were limits to that patheticness.
For instance, if Shu made an oath like “as a price for eating less meat bun at breakfast tomorrow, exchange it for the next punch to definitely unleash a Black Flash and blow up the head of Six Paths Madara,” such a ridiculous Binding Vow would never be formed.
The essence of a Binding Vow is usually presented in the form of paying the price first, then obtaining the compensation.
Once a Binding Vow is formed, the process cannot be reversed.
If he were to violate the Binding Vow he had set for himself in the future, then the benefits obtained would not only be instantly withdrawn, but he might even suffer a severe backlash.
Among these, Binding Vows with time limits can be violated.
However, permanent Binding Vows, once set, can never be violated in one’s lifetime. Get faster updates on g.com.
In other words, a Binding Vow is a sort of cheap version of Equivalent Exchange.
Whatever you pay, you will receive an equivalent return.
The heavier the price paid, the more abundant the reward obtained.
Naturally, this cannot be compared to the true equivalent exchange in alchemy.
Although the items that can be used as a price to set a Binding Vow are diverse—such as severing a limb, permanently sealing a portion of one’s power, even making an oath to never do “XXX,” or directly sacrificing one’s own life and soul, etc.—all of these can serve as heavy prices for a Binding Vow, but that does not mean a Jujutsu Sorcerer can exchange for whatever they desire.
The ceiling of a Binding Vow lies in the fact that it can, at most, only enhance certain attributes one already possesses, such as the upper limit of Cursed Energy output, precision in technique release, attack range, and so on.
It absolutely cannot make a Jujutsu Sorcerer add total Cursed Energy to their body from nothing, cannot create matter that didn’t exist before, and absolutely cannot perform things the user is fundamentally incapable of.
However!
Using it to forcibly increase control precision and output power—this is the field where Binding Vows truly excel!
Along with the oath Shu made in his heart.
*BUZZ!*
Shu sensed clearly that, from out of nowhere, it felt as though an invisible shackle had fallen upon his soul.
From this moment on, he had lost the possibility of ever using his own Innate Technique.
Though, because all these exchanges in the Main God Space were piecemeal, he didn’t even know what his Innate Technique was yet!
But in return!
He felt that his perception of the Cursed Energy within his body, his control ability, and his output power had undergone a qualitative transformation that turned heaven and earth upside down.
If previously when he moved Cursed Energy, his output channel was like a small stream…
Then now, that channel was instantly widened into a rushing, mighty river.
He could even feel that he could control the flow and shape of every single strand of Cursed Energy with precision.
“Undoubtedly, this is a ‘borrowing’ style of cultivation!”
Shu felt the extremely fluid control of Cursed Energy within his body, as if he were moving his own arm, and felt incredibly satisfied.
Using an unknown Innate Technique to exchange for extreme control power and the output capability he needed most right now—this transaction was truly very profitable.
Moreover, he hadn’t truly become a technique-less isolator forever unable to use any techniques.
One must remember, this is the Main God Space.
So, couldn’t he just spend money to exchange for other techniques from the Main God Space?!
In a place where even God-tier bloodlines can be purchased, as long as Plots and Reward Points are sufficient, don’t talk about ordinary Cursed Techniques; even if a Reincarnator wanted to exchange for the Limitless or the Ten Shadows Technique, that was a matter that could be settled in minutes.
“Finding loopholes in settings is indeed a traditional virtue of a Reincarnator.”
Shu hid the smile at the corner of his mouth and no longer thought about those distant, strange operations.
He held his breath and focused his mind, adjusting his Cursed Energy to its best condition.
After preparations were complete, the procedure was the same as before.
Shu directed the Cursed Energy precisely toward the optic nerve node.
This time, thanks to the qualitative change in control precision, that abundant Cursed Energy didn’t leak or waste a single bit, and was entirely injected into his Sharingan!
*SHUA!*
Along with the final drop of Cursed Energy being squeezed out and fully injected into both his eyes.
Within Shu’s blood-red vision, the Sharingan that previously only had two tomoe was now undergoing a magical high-frequency resonance!
Accompanied by fluctuations of chakra, a third, jet-black tomoe slowly emerged on the edge of his pupils!
Three-Tomoe Sharingan!
The three tomoe connected end-to-end, rotating at a constant speed within his pupils.
Shu slowly stood up and observed his surroundings.
With the support of the Three-Tomoe Sharingan, his dynamic vision, detailed observation ability, and perception of energy flow had all experienced a massive qualitative leap!
Even the trajectory of tiny dust motes floating in the air, and the subtle light refraction angles of the Main God Space’s light sphere, were all clearly visible within his mind, as if everything had slowed down.
“Success…”
Shu stroked the corner of his eye, feeling the massive power brought by his eyes.
The thing that made him feel most relieved was that opening his eyes this way would not stimulate his mind at all, so he wouldn’t end up like those Uchiha.
The higher the level of the eyes opened, the more extreme their mental states became, eventually turning into lunatics who shouted, “I want to create a world that has Rin!”
With 1 Rank-C Plot, he had forcibly managed to pry open the Three-Tomoe Sharingan, which was equivalent to a Rank-B Plot!
And he also got a free bonus of Cursed Energy reinforcement at the level of a Grade 3 Jujutsu Sorcerer!
Sure enough!
The core of the Main God Space is not to strengthen a single system step-by-step, but rather to play with the fusion of power systems from the Myriad Worlds—like the operation of stepping on the left foot to lift the right, soaring to the skies!
