First, Shu would have to spend 1 C-Rank Side Plot and 2,000 Reward Points to upgrade to Two-Tomoe.
After that, what remained of his rewards wouldn’t be enough to scrape together another B-Rank Side Plot for Three-Tomoe.
Even if he settled for Two-Tomoe, it would mostly improve his perception and barely increase his actual combat power.
And Mangekyo?
Forget it.
As for awakening it through his own talent, spending over twenty years stuck at One-Tomoe had already proven exactly how terrible his talent was.
If Shu wanted to become stronger, he’d have to rely entirely on the Main God’s exchanges.
‘The chakra route is just too restrictive for me.’ ‘Or maybe…
I should switch tracks?’ ‘Or pull a certain ape and run two energy systems at once?’ With the Main God connecting countless worlds, there was no reason to stubbornly limit himself to chakra alone.
Once that thought occurred to him, Shu’s eyes began rapidly scanning the exchange screen.
He left the Naruto category and started browsing power systems from other worlds.
As he quickly scrolled down the list, one obscure exchange option suddenly caught his eye.
[Low-Grade Cursed Energy] [Description: From the world of Jujutsu Kaisen.
Entry-level Cursed Energy equivalent to a Grade 4 Sorcerer.] [The holder awakens basic Cursed Energy perception and can clearly see hidden Cursed Spirits and Cursed Objects.] [The holder will not suffer mental corruption from the passive curses of Cursed Spirits below Grade 4.] [Grants basic Cursed Energy control.
Cursed Energy may be infused into the body for simple physical enhancement.] [It may also be infused into ordinary weapons, temporarily turning them into Cursed Tools capable of exorcising low-level Cursed Spirits.] [Note: This level cannot use any Cursed Techniques and will not awaken an Innate Technique.] [Exchange Cost: 1 D-Rank Side Plot and 1,000 Reward Points.] “Jujutsu Kaisen, huh?” Shu’s gaze lingered on the option.
The series had fallen apart pretty spectacularly toward the end in his previous life.
It had produced plenty of hilarious memes, like 2.5 Gojo, heading south for the revival match, and Elbow-Spam Kaisen.
And in terms of overall power scaling, even the ceiling of that world—Gojo Satoru and Ryomen Sukuna—wasn’t particularly high-tier within the Main God Space.
On top of that, this exchange was another scam.
Innate Techniques had to be purchased separately too.
But Cursed Energy itself immediately caught Shu’s attention.
What exactly was Cursed Energy?
It was supernatural negative energy created by directly converting and refining human negative emotions such as fear, hatred, despair, and pain.
And what was the essence of the Sharingan?
A certain evil old Senju bastard had once explained the fundamental mechanism behind its evolution.
When an Uchiha experienced an extreme emotional shock caused by the loss of love, their brain secreted a special kind of chakra.
That chakra directly affected the optic nerves, triggering a bloodline mutation in the eyes and causing the Sharingan to awaken or evolve.
‘So here’s the question…’ Shu’s eyes grew brighter.
‘Can Cursed Energy, which is literally formed from negative emotions, directly replace that special chakra secreted by the Uchiha brain?’ After all, both originated from negative emotions given physical form.
In some ways, pure Cursed Energy might even be more extreme than chakra carrying someone’s individual traits.
‘If I directly channel highly concentrated Cursed Energy into an Uchiha’s optic nerves…’ ‘Could I skip the emotional trauma entirely and force the Sharingan to evolve through direct energy infusion?!’ If that actually worked, it would be an insanely cost-effective shortcut.
And he wouldn’t even have to become some legendary “filial son” to do it.
There were risks, of course.
But inside the Main God Space, Full-Body Restoration meant he didn’t have much to fear.
This was absolutely worth testing.
And even in the worst case, if Cursed Energy couldn’t stimulate his Sharingan, the power system itself was still excellent value.
Mechanically, it offered all kinds of Innate Techniques and Domain Expansions with guaranteed-hit, lethal effects.
In raw stats, Cursed Energy could greatly enhance physical abilities.
For recovery, Reverse Cursed Technique could supposedly even heal the brain.
Most importantly, Cursed Energy was specifically effective against ghosts and supernatural entities.
In a place like the Main God Space, where he could be thrown into worlds like Ju-On or Silent Hill at any moment, a power specialized against spirits would be an incredible survival tool.
And Cursed Energy exchanges existed at every level.
They ranged from D-Rank Low-Grade Cursed Energy all the way up to A-Rank Special-Grade Cursed Energy.
“Looking at everything together, the Cursed Energy system really does suit my current situation.” “Then let’s test whether Cursed Energy can evolve my Sharingan first!” Shu made his decision.
“Main God!
Exchange for Low-Grade Cursed Energy!” The moment he spoke, 1 D-Rank Side Plot and 1,000 Reward Points vanished from his account.
A pillar of light immediately descended and enveloped his entire body.
Unlike the warm light of Full-Body Restoration, this time Shu felt an icy power pouring into him.
Only a few seconds later, the light faded.
Shu could now clearly feel a completely new energy resting inside his dantian.
“Hiss…” “This feels completely different from chakra.” He closed his eyes and carefully examined the changes inside his body.
The energy felt cold and viscous, quietly lying dormant around his dantian.
Its operating method was completely different from chakra.
Chakra was produced on demand by mixing physical energy from the body’s 130 trillion cells with spiritual energy.
When not actively molded, its components remained distributed throughout the body’s cells.
Cursed Energy, however, behaved more like internal energy.
It was stored around the dantian and drawn out whenever needed.
“It’s only D-Rank Low-Grade Cursed Energy, but the purity of this negative energy is seriously impressive.” “The amount is pathetic, though.” “Well, that’s expected.
It’s only entry-level Grade 4 Sorcerer territory.” Shu clenched his fist.
The Main God’s exchanges might be predatory, but at least they were generous enough to include basic control appropriate to the purchased level.
He didn’t have to start from scratch and learn how to move Cursed Energy himself.
“First, let’s see whether this stuff conflicts with chakra.” “Last thing I need is some kind of energy runaway.” Shu began molding chakra.
Chakra flowed smoothly through his pathways, while the dark Cursed Energy inside his dantian remained completely stable.
Neither interfered with the other.
They were two entirely independent energy systems operating in parallel.
“Good.
No conflict at all.” Shu let out a relieved breath.
He drew out a trace of Cursed Energy and guided it through his pathways toward his right fist.
A faint sheen immediately appeared over his knuckles.
Shu walked toward the edge of the plaza and threw a punch into empty air.
“Whoosh—!” …
