The Eight Gates technique had always been Satori Hyūga's ultimate forbidden technique in Taijutsu.
The Hyūga Clan had long been a powerhouse in physical combat, and naturally, he had no intention of abandoning such an advantage.
With the enhancement provided by the Byakugan, combined with advancements in genetic science, modifications and combinations of the Eight Gates technique had finally reached a higher level of refinement.
Shinno applied the Body Regeneration Jutsu and Cell Activation techniques to the Eight Gates technique, further refining it through genetic modifications that made the test subjects more compatible with opening the gates.
However, this was only the first step.
This initial stage allowed individuals to unlock all Eight Gates, greatly enhancing defense, attack power, speed, agility, and overall Chakra reserves.
The second stage involved Shinno's deeper enhancements to the test subjects. Bei Gongcheng received Lightning Release abilities along with a Lightning Armor, granting him a second-stage transformation.
In this state, Bei Gongcheng converted his Chakra into Lightning Chakra, forming a lightning-based armor around his body.
Once equipped with the Lightning Armor, both offensive and defensive capabilities were vastly improved—each movement radiating with the sheer force of thunder.
Right now, on the screen above, Bei Gongcheng had successfully entered this state.
Lightning surged around him as he radiated divine might, as if the Thunder God himself had descended—unmatched and unstoppable.
Faced with this transformation, Jiraiya couldn't help but recall the Ab brothers from the Cloud Village.
Same muscular build, same powerful physique, electrified presence, delivering devastating punches—it was uncannily similar.
Jiraiya kept dodging while summoning frogs using the Summoning Technique to counterattack.
At this point, he was still not fully proficient in Sage Mode and couldn't activate it during battle. Forced to retreat while fighting, he improvised under pressure.
On the other side, Kondō—who had been standing idle for quite some time—suddenly opened his eyes.
His pupils were pitch black, resembling voids, radiating a sinister, malevolent aura.
Near the battlefield, waves of fear, terror, death, and ill omens gathered, sending shivers through Kondō's mind.
"So intense... such dark power. It's utterly intoxicating."
Without even joining the fight, the dense negative emotions surrounding the battlefield unconsciously triggered his second-stage transformation.
Kondō's two-stage transformation system originated from Shinno's original concept—a form based on Dark Chakra.
In this mode, he could infinitely draw upon the darkness hidden within people's hearts as a source of Chakra.
The benefit of this power was that it didn't require drawing Chakra from his own body—it was purely external energy.
As long as there were others nearby, he could continuously siphon their inner darkness and negative emotions.
This form granted unending physical stamina beyond the Eight Gates, with increasing strength with each passing moment.
It was a mode designed for the final stages of battle.
The drawback, however, was that if someone blocked the acupoints and meridians controlling Chakra flow in his body, he'd be completely incapacitated in an instant.
In the original series, Shinno was defeated when Sasuke—possessing the Sharingan—saw through this weakness and sealed his acupoints and meridians with a few well-placed needles.
Dark Chakra surged outward from Kondō's body as his presence spread, locking onto those consumed by genuine fear and draining their negativity.
One by one, ninja were bound by chains of Dark Chakra, transformed into living batteries fueling Kondō's monstrous power, making his aura grow ever more terrifying.
His jet-black hair flowed down to his waist, similar to the Saiyan beside him.
Those he had entangled lost all ability to move and could only let him extract energy and negative emotions from within their bodies.
Feeling another massive surge of dark chakra, Jiraiya silently cursed under his breath.
He had just brought his apprentice out for a simple mission—never expecting to encounter such a difficult situation.
One enemy was already extremely troublesome, and now another was now at his side.
Just as he was straining to enter Sage Mode, his opponent suddenly stopped advancing and ceased his attack.
"Huh? Why'd you stop? You're not thinking about switching places with someone else to fight me, are you?"
Jiraiya looked up and saw Bei Gongcheng, who seemed to be receiving orders, begin walking away without even glancing back.
Not far away, Minato shouted anxiously, "Professor Jiraiya! Bad news—the employer is dead!"
Jiraiya glanced toward the Great Daimyo of the Land of Rice Fields and felt his stomach drop. The client really was dead.
The Great Daimyo had been bound by chains of Dark Chakra, linking his mind directly to its influence. His innermost fears were then infinitely amplified.
After all, these people had come specifically to kill him. Not even the combined forces of so many ninja and samurai could stop them—who wouldn't be terrified?
Fear kept growing, flooding over him until the nervous-by-nature man died from sheer terror.
Seeing the client's death, Jiraiya helplessly scratched his head and let the enemies leave without further resistance.
With the target gone, there was no point in fighting anymore.
If the client had still been alive, failing the mission would mean answering for failure. But now that he was dead, things became much easier—no complaints, no problems.
He never lingered on regrets, so he immediately called for Minato and Kushina, preparing to leave.
Before departing, Jiraiya gazed at the retreating enemies and the airborne fortress, murmuring to himself, "Shinno… What a terrifying covert faction. I must report this to my master."
This group had suddenly appeared, with deep connections to the Sky Ninja from the Second Great Shinobi War. It was likely they might in fact be the original Sky Ninja faction.
Faced with a potential threat, thorough preparation was necessary—gathering intelligence and swiftly developing tailored countermeasures.
Who knew when the enemy might strike again?
But their act of distributing seeds puzzled Jiraiya greatly.
He collected some of these seeds and returned to Konoha accompanied by Minato and Kushina.
Bei Gongcheng and Kondō returned to the airborne fortress, where specialized researchers immediately began collecting data on the test subjects.
The results from this first trial were particularly important.
Despite treating the weak researchers like insignificant insects, Bei Gongcheng and Kondō did not resist the examination, allowing full access to inspect their entire beings.
After all, just because someone was weak didn't mean those behind them weren't powerful.
After thirty minutes of rigorous testing, every bodily change had been recorded.
Satori Hyūga received the test reports instantly and began reviewing them carefully.
[Thunder Chakra Sage Transformation] consumed excessive energy but delivered immense destructive power. Most ninjutsu couldn't inflict real damage on him.
Kondō hadn't engaged in actual combat, but once he activated his [Dark Chakra Sage Transformation], his body and psyche underwent noticeable changes.
Examinations confirmed that Dark Chakra had indeed exerted measurable effects—both on his body and gradually corrupting his personality.
This erosion would occur silently, gradually unleashing his brutal and savage nature.
Moreover, the powerful Dark Chakra Chains increased his dark chakra reserves.
It was undoubtedly a path of demonic cultivation within the ninja world.
However, one involved extracting bones and marrow, refining souls, and consuming essence, while the other absorbed negative human emotions.
"Dark Chakra Mode isn't as convenient as anticipated. It still requires further research and improvements."
Satori Hyūga carefully reviewed the report before delegating new missions.
The reason for his emphasis was simple—he wanted both modes.
Not just the Dark Chakra Mode and the Lightning Release's Eight Gates Mode, Satori even wanted to develop Eight Gates transformations for other elemental natures.
If it worked with Lightning Release, then why not with other natures as well?
Though he looked like a child, Satori's potential was boundless.
