Chapter 176: Creation Rebirth, Sage Mode!

For Shūichi, this was just a minor accomplishment, hardly worth dwelling on.

With a few strokes of his pen, he recorded the formula for his new Fire Nether Chains and then stored it away. This would be a valuable asset for the the future.

Afterward, his attention turned to the Tag Tree.

The new Fire Nether Chains had been recognized by the Tag Tree as an S-rank sealing technique, which meant he could now activate the Sealing Master tag.

As the tag leaf was filled with a red glow, its effects came into play: sealing and curse mark talent increased by 100%, thought processing speed increased by 100%, and the ability to crystallize a sealing technique into a kekkei genkai with no barriers to learning any non-bloodline-based sealing or curse marks.

"A red tag… So, even Master-level tags can have different ranks!"

Shūichi was overjoyed.

Currently, the strongest tag on his Tag Tree was Prodigy, his only golden tag so far.

But solidifying a sealing technique as a kekkei genkai was astonishing in itself.

Without hesitation, Shūichi chose the Fire Nether Chains, his own S-rank sealing technique.

Immediately, intense pain seared through his body.

It felt like every cell was being branded by fire.

And he could feel his chakra transforming into symbols, forming the Fire Nether Chains formula, compacted a thousand times over and forced directly into his genes.

"So intense…"

Shūichi couldn't help but suck in a cold breath.

This was nothing like his previous experience of learning Lava Release, where the power permeated gradually, quietly making itself known.

But once the pain faded, Shūichi realized a benefit.

By crystallizing the Fire Nether Chains as a kekkei genkai, the Tag Tree had perfected the information, something he couldn't achieve on his own.

This meant that his descendants would inherit the Fire Nether Chains as close to his own level as possible.

And future generations would also have a higher chance of awakening it.

After all, genetic information can lose its integrity through generations.

Of course, for Shūichi himself, having the Fire Nether Chains as a bloodline limit wouldn't enhance his strength directly.

"Even so, the Fire Nether Chains have not yet reached their full potential. There's still room for growth."

Shūichi had high hopes for this sealing technique.

Currently, the Fire Nether Chains were based on Fire Release and Yin Release.

He had considered integrating Yang Release to further enhance its sealing power, aiming to make it Yin-Yang Release.

One day, it might even rival the Six Paths Chibaku Tensei.

Of course, that goal was still a ways off.

Putting that thought aside, Shūichi continued sorting through his latest achievements.

Second goal: Yang Release.

With a clap of his hands, Shūichi was suddenly surrounded by a brilliant green chakra glow.

Instantly, the vitality in each of his cells surged, and his life force skyrocketed.

One times... two times... three times!

At three times the normal level, he reached his limit. He then released his hands, pulled out a kunai, and sliced his arm. The wound opened immediately.

But before any blood could flow, it healed in an instant.

"Not bad—it's not as good as the First Hokage, but it's certainly on par with the lower White Zetsu."

Nodding in satisfaction, Shūichi deactivated the technique.

This time, he had used only his own chakra, as his chakra level had already reached the level of a Tailed Beast, eliminating the need for Yin Seal support.

The drawback was that, once activated, the technique's healing became uncontrollable.

Even minor injuries would trigger rapid cell division and accelerated healing, risking overuse.

This technique's effect was similar to Tsunade's original Creation Rebirth.

"I'll call it Creation Rebirth, then!"

Not putting much thought into naming, Shūichi began drafting the technique on a blank scroll. He intended to give this to Tsunade.

However, he added the Hundred Healings technique to the scroll's formula.

This was not just because Tsunade and others lacked sufficient chakra; even Shūichi himself would combine it with the Yin Seal in future use.

Once he finished writing the formula, Shūichi paused and continued writing down his future thoughts and directions for the technique.

The healing effect of Creation Rebirth was beyond question, but Shūichi saw some shortcomings.

First, it only worked on himself.

Second, it lacked control.

Moving forward, Shūichi aimed to enhance cell vitality—or, rather, the power of Yang Release—to reach or even surpass Hashirama's level.

Second, he wanted to study Asuka's cells to refine Creation Rebirth, making it controllable and allowing it to heal others.

Finally, he hoped to make these enhancements permanent, forming a bloodline limit.

After finishing, another thought struck him: "Making these effects permanent is actually achievable for me since my body is already as strong as a Tailed Beast, with Yang Release properties meeting the requirements for self-healing without seals."

"It's Tsunade and the others who would struggle. Both Tsunade and the director have sufficient talent, with mastery over the Hundred Healings Technique and the Yin Seal, so they can use Creation Rebirth without issue, but solidifying it as a bloodline would be out of their reach."

"Then there's Shizune. She doesn't have Tsunade or the director's talent. Forget about solidifying it; I'm not even sure if she can master it."

"To enhance their physical capabilities without transplanting Hashirama's cells, there may only be one path left."

The Bijuu Sealing mark!

Or, in other words, Sage Transformation!

The fire-based enhancement he named Bijuu Sealing mark might need a different name if adapted to boost cell vitality.

"Combining the Natural Curse Mark, Hundred Healings, Yin Seal, and Creation Rebirth…"

As he pondered, Shūichi stored the scroll for Creation Rebirth and pulled out another blank scroll to start writing.

He'd only spent three minutes on Creation Rebirth, so the remaining three minutes didn't allow him to reach his ideal goal with the Bijuu Sealing mark, but it was progress.

He had managed to outline a basic formula.

Quickly, he completed the formula.

Shūichi then laid the scroll out on the floor and sat in the center of the formula.

With a clap of his hands, Shūichi closed his eyes, bringing his focus to its peak, and then activated the formula on the scroll.

The next moment, Shūichi felt an immense flow of natural energy surging into his body, merging with every cell, transforming into a powerful life force that rapidly boosted his cell activity—surpassing the effects of Creation Rebirth in an instant, reaching four times his usual baseline!

Moreover, he sensed a substantial increase in his strength, physical resilience, and reaction speed.

This far outperformed Creation Rebirth in that regard.

The Amplification of Yang Release!

However, this formula lacked the ability to store natural energy.

But Shūichi was confident that he could merge it with the Bijuu Sealing mark.

Disabling the technique, Shūichi stood and stored the scroll. "Still needs a step-by-step refinement."

"But I should also try out Sage Mode myself."

Putting the scroll away, Shūichi stood in the center of his study, closed his eyes, and easily sensed the vast natural energy all around him.

Immediately, he began to absorb a large amount of natural energy, combining it with his own spiritual and physical energy in a 1:1:1 ratio, refining it into Sage Chakra.

Sage Mode, activated in an instant!

Opening his eyes, Shūichi picked up a mirror to check, and sure enough, there was no sage mark on his face.

His chakra control was so refined that the Sage Chakra caused no visible effects on his body.

Just as he could fully activate the Hundred Healings Technique without developing curse mark patterns on his skin, Shūichi noted with satisfaction, "From an enhancement standpoint, Sage Mode is undoubtedly superior to the Bijuu Sealing mark."

"Especially in sensory range—it surpasses my Listening technique, and combining them makes it even more remarkable, not only broadening the perception field but also making it more precise."

"However, Sage Mode relies on absorbing natural energy in one go to refine it into Sage Chakra, and once it's exhausted, I have to reabsorb, which can be dangerous during combat."

"The Bijuu Sealing mark, however, can store natural energy and sustain itself continuously."

"When using Fire Release Chakra Mode, Blaze Release Chakra Mode, or Lava Release kekkei genkai, the Bijuu Sealing mark still outperforms Sage Mode."

Of course, for Shūichi, the two techniques didn't conflict.

"So, I should keep optimizing the Bijuu Sealing mark to enhance it comprehensively, making it comparable to Sage Mode. This way, it would be like Sage Mode in curse-mark form, allowing me to maintain it for extended periods—up until my own stamina is depleted."

With that in mind, Shūichi gathered his things and used the Flying Thunder God Technique to teleport directly to the research base.

In an office at that moment, Tsunade was frowning as she examined recent experimental data.

Shūichi stepped forward and handed her a scroll.

Tsunade looked up, frowning. "What's this?"

Shūichi grinned. "An S-rank medical ninjutsu—completed!"

Tsunade froze, then exclaimed in shock, "How… is that possible?"

"How did you finish so quickly?"

Shūichi raised his chin smugly. "Now you see how amazing I am?"

"Take a look. Paired with the Yin Seal and the Hundred Healings Technique, you shouldn't have any trouble using it."

"Of course, it's not perfect yet; once activated, the self-healing is uncontrollable."

Tsunade hurriedly took the scroll, and as she reviewed it, her shock only grew. "You… you really managed to pull it off."

"But you just said yesterday that you still had a bit left to complete."

Shūichi nodded, "I did. So today, I completed that bit."

Tsunade gave him an exasperated look, then blinked in surprise. "It requires only one hand seal?"

Shūichi chuckled, "That seal is for your use."

Tsunade clenched her fist, tempted to punch him. "You really have a way of getting on my nerves with that attitude."

Shūichi sighed, "One must recognize reality; certain gaps are inevitable."

Tsunade gritted her teeth, resisting the urge to throw a punch.

After nearly half an hour, Tsunade finally put down the scroll. "It's extremely well-crafted and more than enough for our use."

With that, Tsunade stood up. Instantly, the Yin Seal symbol on her forehead lit up, followed by the Hundred Healings Technique's curse markings spreading across her body, and she formed the hand seal.

Ninja Art: Creation Rebirth!

"The vitality is on par with White Zetsu cells, though it still falls short of my grandfather's cells, but it's enough to handle most injuries," Tsunade observed.

Shūichi replied, "Our research still has to continue, like making this technique usable on others."

"And also, finding a way to control self-healing."

The first part, in fact, he had a rough solution for: merging it with the Yang Release natural energy amplification formula he had recently completed.

Clearly, the curse mark is best suited for those close to me.

Tsunade nodded and, after deactivating the jutsu, asked, "Do you have any ideas on solidifying cellular activation?"

Shūichi replied, "Once Yang Release's nature transformation is strong enough, it can be solidified, but it also requires sufficient energy, meaning a strong enough physique and chakra reserves."

Tsunade understood instantly. "Yes, that makes sense."

Shūichi added, "Of course, there's one more way."

"You must know about Sage Mode, right, Tsunade?"

She nodded. "Of course."

"Shikkotsu Forest has a Sage Art inheritance, but I never mastered it."

Mentioning Shikkotsu Forest, Tsunade continued, "Shūichi, you should make time to form a summoning contract with Shikkotsu Forest."

Shūichi thought for a moment, then replied, "It's better if Shizune and Asuka handle that."

"I'll focus on combat, and you all can handle the healing."

Tsunade didn't insist and nodded in agreement. "That works."

Shūichi steered the conversation back. "You already know about the Bijuu Sealing mark. I've managed to develop a new jutsu formula that can further amplify Yang Release."

"We could use the Hundred Healings Technique to link the Yin Seal and curse mark, solidifying cell activation—essentially enhancing your current state with my curse mark."

"Though it may not reach the full level of Creation Rebirth, the effect will still be impressive."

Currently, Tsunade's chakra is subtly nurturing her cells to slow down aging and maintain her physical state.

"Is that so?"

Tsunade was intrigued. "With that curse mark's amplification, the effect should be promising. When do you think you can finish developing it?"

Shūichi felt a bit speechless.

When it comes to beauty and youth, women seem to have zero resistance—especially older ones!

Of course, he dared not voice this thought, lest he get punched.

"It shouldn't be too difficult," he assured, then promised, "After New Year's, definitely before my birthday."

"Speaking of which, Tsunade, what do you plan to get me for my birthday?"

Tsunade's expression shifted instantly. "Why would I get you a gift?"

Shūichi pouted, "Stingy!"

She glanced at the necklace Shūichi wore.

That necklace was her most cherished possession, and this brat was still so greedy!

Birthdays weren't that important for a shinobi, anyway.

"Tsunade, you have hemophobia, don't you?"

Shūichi suddenly asked.

Tsunade replied, "Did Shizune tell you?"

Shūichi shook his head. "Just a guess."

"That's probably why you've avoided the battlefield, unable to even work as a medical ninja in the Konoha Hospital or on the frontlines."

Tsunade remained silent.

Shūichi continued, "I might have a way to cure you."

Tsunade raised an eyebrow. "What method?"

"It's not a physical condition, after all."

Shūichi nodded. "I know that, of course. As for the method, I'll keep it under wraps for now—saying it out loud might lessen its impact."

"All you have to do is decide whether or not to let me try."

Tsunade was quiet for a moment before saying, "If you want to try, go ahead. Just don't get your hopes up."

Shūichi grinned. "Don't worry; I'm not that fragile."

"Alright then, it's decided."
