Izuna Uchiha's Research Progress
The entire laboratory area was enveloped by several layers of barriers, isolating it from the outside world and preventing the effects of the spell from spreading to other areas of the island.
The heavy doors, constructed of metal and rock, slowly slid open to both sides, releasing a faint aura of medicine, reagents Chakra fluctuations.
The laboratory was filled with a dense array of instruments, and sealed containers of all sizes were neatly arranged. The containers contained Hashirama Cells and Natsu's cell samples, with various colored culture media flowing slowly. Countless runes and spell patterns were engraved on the walls and floor, with a faint glow flowing around them.
Izuna Uchiha stood in front of the experimental table.
He still possessed the body created through the Impure World Reincarnation, but the grayish-black surface of the Impure World Reincarnation had undergone countless improvements and refinements, no longer resembling its rough and unpalatable early form.
After a long period of research and debugging, and repeated modifications using a special Gene Serum formulated from Hashirama Cells and Natsu cells, this reborn body has been completely transformed.
Now, he can fully unleash the fighting power he possessed during his prime.
Moreover, the addition of two high-quality cells caused his Chakra reserves to surge, making him even stronger than at his peak in life.
No matter how powerful it is, it is ultimately just a puppet body Impure World Reincarnation.
True rebirth, completely freeing oneself from the shackles of the Impure World Reincarnation, remains a distant prospect.
According to the previously agreed plan, to achieve a true resurrection, Madara Uchiha must successfully fuse with the Gene Serum, awaken the Rinnegan, and obtain the basic conditions for the Rinne Rebirth Technique before anything can be officially put on the agenda.
Izuna Uchiha traced the spell scroll floating in front of him with his fingertips. Countless intricate runes flowed and danced on the surface of the scroll. He spent most of his time in this secret room.
After arriving in this world, he had almost no time to rest, constantly iterating and perfecting the various parameters of the Impure World Reincarnation.
While burying himself in researching and simplifying the Flying Thunder God Technique, he also helped refine and complete the various new Ninjutsu conceived by Natsu.
Flying Thunder God, a unique Space-Time Ninjutsu.
Even though the Uchiha Clan possesses numerous and terrifyingly powerful Forbidden Technique, spatial abilities still belong to the most profound category.
The threshold for mastering the Flying Thunder God is so high that it is daunting. The requirements for Chakra control precision, instantaneous mental calculation, and spatial perception are almost abnormally demanding. Most geniuses in the clan, even after years of hard work, cannot even touch the threshold of entry.
Hearing footsteps approaching, Izuna Uchiha looked up and saw Natsu walking slowly into the laboratory. A hint of surprise and doubt flashed across his eyes.
"Why are you here at this hour? What happened?" Izuna Uchiha put down the stone pen used to record the parameters of the spell and gently closed the unfolded scroll.
Natsu walked to the lab bench, her gaze sweeping over the densely packed calculation drafts and the mountain of spell scrolls, with tiny specks of Chakra floating in the air.
"No unforeseen circumstances." Natsu shook her head slightly, her gaze falling on the several parchment scrolls filled with calculations of the Flying Thunder God technique. She got straight to the point, "I came here to ask about the progress of the simplified version of the Flying Thunder God Technique."
Upon hearing this question, Izuna Uchiha let out a soft breath, reached out and took the thick scroll from the top, laying it flat on the stone table.
The scroll was covered with layers of revisions, erasures, and rewrites. Countless spatial coordinate formulas and Chakra flow routes were densely covered on the paper. Every change represented countless days and nights of deduction and trial and error.
"The basic framework is complete." Izuna Uchiha lightly tapped a core rune on the scroll with his fingertip, his tone tinged with fatigue, yet also revealing a hint of satisfaction at completing the research.
"I stripped away some of the overly complex spatial calculation logic from the original Flying Thunder God, rewrote the Chakra conduction path, and lowered the threshold for sensory talent required to get started."
If one cultivates according to this improved version, a group of clansmen with above-average talent will already have the potential to begin, unlike the original version where only one in a thousand geniuses are qualified to even attempt it."
At this point, his brows furrowed slightly, and his tone turned somber as he frankly pointed out the unavoidable shortcomings of this simplified technique.
"However, the flaws are also quite obvious."
First, the teleportation distance has been greatly reduced. The original Flying Thunder God could make long-distance jumps across large areas of sea, but the simplified version can only cover a range of a few thousand meters at most in a single teleportation.
Secondly, the stability of the coordinate markers has decreased. The original Flying Thunder God technique markers can remain for a long time even after violent impacts and artillery bombardment.
The simplified markings will be directly erased by high-intensity Haki impacts and powerful Ninjutsu bombardments.
"And there's one more crucial point." Izuna Uchiha looked up at Natsu, his expression serious, "The reaction speed for instantaneous spatial teleportation is not as fast as the original."
In the face of a high-speed surprise attack and a life-or-death struggle, this simplified version cannot achieve the near-zero-delay evasion of the original.
Simply put, it's suitable for long-distance raids and tactical maneuvers, but relying on it for emergency evasion in life-or-death combat remains extremely risky.
As he spoke, a complex mix of emotions welled up within him.
Impure World Reincarnation body, enhanced by the drug, possessed strength and Chakra that surpassed its former self, but it was still not made of flesh and blood.
Without a beating heart or flowing warm blood, no matter how much power one gains, one is essentially still an undead sustained by spells.
He had imagined countless times, alone in the dead of night, what it would be like to be truly resurrected.
Freed from the shackles of Impure World Reincarnation, possessing a true physical body of their own, no longer subject to the control of the caster, and no longer fearing the dissipation brought about by the Sealing Jutsu.
But all hope was placed on Ban, who was traveling far away in the East Blue.
Madara must successfully integrate the complete set of Gene Serum and Awakening the Rinnegan before the resurrection plan can proceed.
If anything goes wrong on Madara's side, he will be trapped in this Impure World Reincarnation body forever.
He rarely revealed this secret to others, even when facing Natsu, he kept it buried deep in his heart and never showed it easily.
After listening quietly to Izuna Uchiha's complete explanation of the improved Flying Thunder God, Natsu bent down to carefully examine the runes and calculations on the scroll. Her fingertips lightly traced several key spell nodes in the air, and she quickly assessed the practical value and limitations of this spell in her mind.
