Saving the Uchiha clan starts with becoming the clan leader.

"Hiruko, you should close the door tightly when you're doing experiments. That scream is a bit creepy." Zongxian walked into the huge laboratory and saw one Hiruko after another running back and forth, so busy that it gave people a sense of urgency.

"Lord Hokage? You arrived really quickly. I was just about to send someone to fetch you."

"So the experiment has made progress?"

"We'll be able to conduct the final step of the experiment soon."

This wasn't the kind of perfunctory "wait a minute" or "it'll be done soon" followed by ten minutes of waiting without seeing anyone. When Hiruko said "soon," he meant it. About ten seconds after he finished speaking, the clones who had been busy gradually finished their work and then turned into chakra smoke and dissipated.

Only Hiruko's original body and Sogen remained, standing in front of the suspended experimental subject.

"Storm Release contains the properties of water and lightning, Lava Release has the properties of fire and earth, and Magnet Release bloodline limit with the property of wind completes the five nature transformations of chakra. Kaguya's Shikotsumyaku is the symbol of Yang Release. Next... is the final step, injecting the bloodline limit symbolizing Yin Release power into the recipient. At that time, Yin and Yang, water, fire, wind, lightning, earth, the seven natures will merge into one."

"Hiruko said softly."

"Is only the final Yin Escape technique missing?"

Zongxian looked up at the experimental subjects who were suspended by iron chains.

This is a death row inmate.

Originally a ninja from a small clan, he killed his father and brothers for the clan's ninjutsu scrolls passed down through generations, becoming a wandering ninja. Unfortunately, his wandering life did not last long, as his atrocities of robbing merchant caravans during his travels attracted the pursuit of Konoha.

then,

He appeared on Hiruko's operating table and underwent Hiruko's Oni-Garara Technique along with nearly a hundred death row inmates. Perhaps it was his talent or his good luck, but he survived the repeated modifications and acquired a total of four bloodline limits.

I was fortunate enough to become the third experimental subject for Zongxian to observe the combination of Yin and Yang Escape techniques.

correct,

The experiment personally overseen by Hiruko was to create the 'perfect ninja'.

but,

Creating perfect ninjas was not the goal. What Sogen needed was to understand how the Yin and Yang Release within the bodies of perfect ninjas could truly merge together, and how the five chakra natures could be harmonized without conflict. Unfortunately, Hiruko's first experimental subject, after becoming a perfect ninja, only existed for seventeen seconds before completely collapsing and decaying, turning into a pool of dark red blood, with only a thin layer of human skin covering it.

The second test subject existed for a shorter period of time.

It lasted for less than five seconds before turning into ashes, leaving nothing behind except its clothes and accessories.

"Hopefully this time it can last a little longer. Both times it lasted less than twenty-five seconds in total, so there's really not much to observe." Zongxian opened his eyes wide and looked up and down at the chakra flow in the test subject's body, which was completely different from that of an ordinary person.

"Having learned from the previous two experiences, I discovered several flaws in the Ghost Sprout Technique and have corrected them all. This time, it will definitely last longer."

Hiruko chuckled twice and explained.

Making two failed products in a row certainly gave him a bad reputation, but he was also secretly glad that he hadn't been able to absorb the Sharingan's power to complete his final evolution. Otherwise, he might have turned into a pile of unknown trash.

Death was not frightening to him.

On the contrary, his use of the Ghost Sprout Technique was not perfect enough, which ignited a strong fighting spirit in his heart. He thought that before he died, he should try to further improve the Ghost Sprout Technique. He didn't want it to be truly perfect, but he didn't want it to become a death warrant.

Let's begin!

Zongxian didn't say anything more.

He didn't care how much Hiruko improved the Demon Spear Technique; all he needed was the mystery of the seven chakra nature transformations within the so-called perfect ninja created by Hiruko. After so many years of exploration, he had confirmed that the awakening of the Rinnegan required the perfect fusion of Yin and Yang, as well as the seven chakra natures of water, fire, wind, lightning, and earth.

just,

How exactly to do it?

Zongxian still had no clue.

Blinding around like a headless fly is far too time-consuming, so he needs these so-called perfect ninjas created by Hiruko to help him with his references.

With permission granted, Hiruko stepped forward, aimed the prepared syringe at the thigh of the suspended test subject, and plunged it in, injecting the Uchiha gene serum, which had been refined using the Oni-Garaku technique, into the test subject's body.

There are very few bloodline limits in the ninja world that possess the power of Yin Release.

After much investigation, Zongxian discovered that only the Uchiha and Kurama clans possessed bloodline limits centered on Yin Release.

Helpless

Zongxian could only take out Obito Uchiha's thigh.

The materials were given to Hiruko to extract the genetic material of the Uchiha clan. Konoha had no shortage of other bloodline limit materials, as there were plenty of corpses of bloodline limit users collected. As for the Shikotsumyaku bloodline limit, it was obtained from Kimimaro under the guise of a physical examination.

"Ahhhhh!!!"

The frantic howling echoed through the room once again.

The suspended experimental subject struggled frantically, but his limbs and neck were bound by sturdy iron chains, and his physical strength alone was not enough to break free from such restraints. Of course, this was only at this stage; it was hard to say what he would become after completing the final evolution.

Hiruko moved aside, making room for the Hokage.

then,

He stared intently at the evolving experimental subject.

Dramatic changes are taking place.

The test subject's aura surged like bamboo shoots after a spring rain, their chakra flowing like a torrent. Yin Release, Yang Release, and the seven natures of chakra—water, fire, wind, lightning, and earth—intertwined and mingled, their boundaries gradually blurring and their differences disappearing...

"Roar!!!"

The painful howls turned into a beastly roar.

The test subject's eyes were bloodshot as he glared at Zongxian and Hiruko standing before him. "You, you beasts, I'll kill you all!!"

"Hmm? Has the tongue regenerated?"

Hiruko looked at the experimental subject who had spoken with surprise.

To prevent the test subject from being too noisy, a section of his tongue was cut off from the beginning. Now that the test subject can speak, it can only be said that he has regenerated his tongue, which is something that has never happened before.

"Beast? Humph! How dare you say that."

Zongxian smiled.

He was certainly no good person, but the test subject himself was even worse, capable of harming his own father and brother. Zongxian was far inferior to such scum and trash.

"I'm going to kill you all, I'm going to kill you all."

The emotionally charged test subject suddenly opened his mouth and spat out a bright laser beam that struck the illusory ribs wreathed in deep crimson flames. This sudden attack did not harm Zong Xian in the slightest, but instead gave him a pleasant surprise.

"Abandoning hand seals and releasing the technique directly is not unusual, but... why wasn't the chakra refined?"

Zongxian stared intently at the experimental subject.

To be honest, if someone hadn't been prepared, most Jonin would have suffered some losses from that move, but it would only have caused some damage, not enough to be fatal. As for Sogen, it didn't even scratch a hair.

"Lord Hokage, watch out!"

Hiruko saw the crimson magma suddenly surging from the test subject's body and couldn't help but shout. He also possessed the Lava Release bloodline limit, so he knew very well how destructive this thing was. Those iron chains couldn't withstand the erosion of the magma.

really,

The next second, the test subject broke free of the chains and pounced on Zongxian like a demon crawling out of hell.

"Get down on your knees."

Zongxian gave a soft snort.

A giant skeletal hand slammed down from the sky, swatting the experimental subject into the ground reinforced with advanced earth-遁术 (earth-遁术 is a type of earth-遁术 is used to describe a technique or method of swatting flies). Then, it grasped the subject in its palm, holding it like a chick.

The experimental subject was still roaring and struggling.

He attempted to use the power of Lava Release to melt the skeletal hand.

only--

Before the skeletal hand was melted, the struggling test subject suddenly froze, as if all his flesh and blood had been melted away, leaving only a light, floating skin that slipped from the skeletal hand. Once it hit the ground, thick, dark red blood gushed out from his eyes, ears, nose, mouth, and anus.

"Thirty-one seconds, that's more than half a minute."

Hiruko was in a good mood.

"Well done! Hiruko, you did a great job this time."

Hiruko, who had received the praise, was stunned for a moment. He looked at Munen, who had released Susanoo. Was half a minute enough? Moreover... he felt that the Hokage was different from the Hokage just a moment ago.

"I will continue to make improvements, and barring any unforeseen circumstances, the next practical exercise can be conducted in half a month..."

"It's no longer needed."

Zongxian said with a smile.

"That's enough. This experiment can end now. The relevant data... just delete and destroy it. Hiruko, go do other research! But don't worry, you did a great job this time. Without your help, I might have been delayed for even longer. So... don't worry about the death penalty for the next ten or twenty years. Focus on your other research!"

Feeling,

I am experiencing the ultimate joy at this moment.

It was comparable to when he moved into the Hokage's office; no, to be precise, the joy was even stronger than that.

"Finally, we have the resources to take another step forward!"

[Chapter 332. Rinnegan and Graduation]

The spotless mirror clearly reflected those purple, wavy eyes. The light purple looked less ferocious and murderous than the previous scarlet, but it also had a more tranquil and profound feel.

Zongxian blinked.

The eyes reflected in the mirror turned pitch black.

"call!"

A long, drawn-out sigh echoed in the room.

It contained a deep weariness.

"Looks like I'll have to wait patiently." After catching his breath, Zongxian left the private washroom and returned to his office.

About two months ago, he awakened the Rinnegan. There were no dazzling displays or golden lotuses emerging from the ground. Everything was completed silently at the forbidden technique research base. Even Hiruko, who was standing in front of him at the time, was unaware that he had awakened the Rinnegan.

then,

For the past two months, he has been immersed in exploring the unknown.

The Rinnegan is like a bottomless deep sea, with too many mysteries for him to explore. This is different from the Mangekyou Sharingan, which only has two types of eye techniques and Susanoo. Some only have one type of eye technique and Susanoo. But in any case, from the moment he opens his eyes, he clearly understands the depth of his eye techniques. He just needs to expand the depth in the predetermined direction.

However, the Rinnegan is different.

It has too many complex and difficult-to-master capabilities that require time and effort to acquire.
