Early Advancement (2)

That night, Shiraha's Wood Spirit Avatar, "Uchiha Issei," left Konoha and secretly went to the Uzumaki Clan grounds.

"Uchiha Issei" received a mission to carry out, which is why he was able to leave Konoha directly.

However, the mission has a time limit. If Uchiha Issei has not returned to Konoha by the time limit, it may cause some problems.

Of course, this is just a buffer measure for Shiraha. The transplantation of the Rinnegan is the most important thing. If more experiments need to be conducted using the Wood Spirit Avatar, then not returning to Konoha is not a big deal. At most, it would just be considered that "Uchiha Issei" has defected.

After years of planning, the concept of Shisui has been reversed.

Most importantly, Chiho also awakened the Mangekyō Sharingan. She was wholeheartedly devoted to Shiraha. With Shisui's assistance and Shiraha's secret efforts, the Uchiha Clan's problems could be perfectly resolved.

At this moment, in the underground laboratory at the center of the Uzumaki Clan grounds, "Uchiha Issei" had already been laid on the experimental table under Shiraha's orders.

With the Wood Spirit Avatar assisting in the experiment, Shiraha was able to directly experience the power of the Rinnegan through the Wood Spirit Avatar's body.

Shiraha Yu quickly Hand Seals, and a ball of light green Chakra gathered in his palms. He then placed his palms on the forehead of the Wood Spirit Avatar.

Using a modified version of the Spirit Transformation Jutsu, Shiraha entrusted a small portion of his soul to Chakra, which was then integrated into the body of the Wood Spirit Avatar.

The Wood Spirit Avatar lying on the experimental table opened its eyes. Shiraha looked at it, and it looked at Shiraha in return.

At this moment, Shiraha had a strange feeling of looking at himself, but he could clearly perceive that the main soul was still Shiraha himself.

"In a way, this can be considered as having an extra life," Shiraha thought to himself.

Even the strongest ninja will die immediately if their body is destroyed, and their soul will enter a place called ' Pure Land '.

Even powerful figures like Hashirama Senju and Uchiha Madara couldn't avoid this, which is one of the limitations of the Chakra system.

As a first-level Spirit Summoning Warlock, Shiraha's soul, Will runes, can even detach from his body and survive for a considerable period of time.

However, in the end, he still needs a physical body to contain his soul.

With the improved Spirit Transformation Jutsu, even if his main body suffers fatal damage and is directly destroyed, he can immediately transfer his soul and then change bodies. Both of his Wood Spirit Avatar are excellent backup bodies.

Of course, this is only one way out for Shiraha. The warlock's soul is naturally the most important thing, but if the body that integrates multiple bloodlines is lost, the impact will be quite significant.

"If Orochimaru knew that the Reincarnation Jutsu he painstakingly researched was just one of the basic abilities that a formal sorcerer (Wizard) could master, he would probably find it even harder to resist the temptation." Shiraha thought of Orochimaru. He really had perseverance. He had not yet integrated the blood that Orochimaru had given him, nor had he shown any signs of practicing the "Companion Serpent Meditation Method".

Coming to his senses, Shiraha took out a fist-sized bottle from his Storage Scroll. The bottle was filled with a pale purple liquid and a special eyeball— the Rinnegan!

The gentle and stable Yang Release Chakra gathered under Shiraha's control, Chakra Scalpel appeared accordingly.

Shiraha reached out and gently touched around the left eye of the Wood Spirit Avatar "Uchiha Issei".

Soon, in less than two minutes, the meridians around the left eye of the Wood Spirit Avatar "Uchiha Issei" were severed one by one by Shiraha.

Through a portion of the soul existing within the Wood Spirit Avatar "Uchiha Issei," Shiraha seemed to feel a tingling sensation around his eyes. This was a slight sensation resulting from his superb Medical Ninjutsu and Yang Release Chakra healing.

If an eyeball were to be transplanted onto an ordinary person, anesthesia would probably be necessary; otherwise, even a ninja would likely find the pain of the transplant unbearable.

However, it seems that ordinary ninjas do not need to use such advanced Medical Ninjutsu as transplanting eyeballs.

Shiraha carefully removed the entire eyeball of the Wood Spirit Avatar "Uchiha Issei" intact and placed it in a pre-prepared Culture Dish.

It's a Three-Tomoe Sharingan and full of Eye Power, so it should be cherished.

Next, Shiraha took the Rinnegan out of the pale purple nutrient solution. With the dual enhancement of magic and "Sixth Sense", his perception became stronger and stronger.

"Sure enough, there are fewer meridians that can be connected." Shiraha compared the Rinnegan with the Three-Tomoe Sharingan of the Wood Spirit Avatar "Uchiha Issei" and found that the Rinnegan's eyeball had many more tiny meridians. In a normal transplant, many meridians cannot be connected, but this was also one of the purposes of Shiraha's experiment.

Shiraha placed the Rinnegan into the empty eye socket of the left eye of the Wood Spirit Avatar "Uchiha Issei". Then, under the effect of his powerful Yang Release Chakra and Medical Ninjutsu, the flesh in the eye socket began to slowly writhe, and the meridians began to connect with the meridians on the Rinnegan eyeball.

Sizzle

A wisp of white smoke slowly rose from around the eyes of "Uchiha Issei," the Wood Spirit Avatar.

Transplanting an eye is much more complicated than removing it, so it takes longer.

In about ten minutes, the eyeball transplant was successful. Except for some meridians that could not be connected, the Rinnegan eyeball successfully merged into the eye socket of the Wood Spirit Avatar "Uchiha Issei".

With Shiraha's control, the Wood Spirit Avatar as "Uchiha Issei," sent Chakra into the eyeball to establish a connection.

At this moment, Shiraha suddenly felt a darkness before his eyes, and a strong and surging Eye Power surged out from the Rinnegan. Even though the soul he left in the Wood Spirit Avatar "Uchiha Issei" was only a small part, he could clearly feel the powerful pressure from the depths of his soul.

For a time, even his physical body was affected.

"Ugh!"

Shiraha subconsciously covered his forehead. At the same time, he retrieved part of the soul and Chakra from the Wood Spirit Avatar "Uchiha Issei".

Lying on the operating table, the Wood Spirit Avatar "Uchiha Issei" was convulsing uncontrollably, as if he were suffering some great pain.

After a long while, the Wood Spirit Avatar "Uchiha Issei" finally stopped convulsing.

With his enhanced perception through his "Sixth Sense," Shiraha discovered that the Energy Particles on the Wood Spirit Avatar "Uchiha Issei" were extremely active, reaching several times stronger than before. The powerful radiation surprised even his own body.

"Very strong radiation, very pure, but also very strange."

Sensing the radiant field, Shiraha made an assessment in his mind and did not absorb it rashly.

After a moment of contemplation, he recorded the physical state of the Wood Spirit Avatar "Uchiha Issei" at this time. Then, he took a deep breath and activated the modified version of the Spirit Transformation Jutsu again.

At first, he only separated a small part of his soul to experience the changes after the Wood Spirit Avatar "Uchiha Issei" transplanted the Rinnegan. This time, he wanted to experience it more directly.

Shiraha directly separated his entire soul from his body and completely entered the body of the Wood Spirit Avatar "Uchiha Issei".

The next second, an immense pressure filled Shiraha's entire body. He felt as if he were on a deserted island in the deep sea, with the sea breeze constantly whipping up huge waves that crashed against the island, carrying away the soil and sand. All around him was a dark, boundless expanse of seawater. A sense of loneliness and terrifying pressure filled his heart.

The dual pressure of physical and psychological oppression felt like it was about to devour a person.

As Shiraha controlled the Wood Spirit Avatar "Uchiha Issei" to use Chakra to enter the Rinnegan, this feeling became even more pronounced.

"Is this the Eye Power of the Rinnegan?" The terrifying Eye Power surged like a tidal wave, relentlessly assaulting Shiraha's mind and body, making him feel extremely uncomfortable. However, with Shiraha's mental fortitude and strong will, he did not lose his mind because of this, but instead continued to resist the impact of the Rinnegan's Eye Power.

At this moment, Shiraha did not notice that the Wood Spirit Avatar he controlled, "Uchiha Issei," had unconsciously activated the Sharingan in his right eye. Within the scarlet iris, three tadpole-like Tomoe were evenly distributed, and there were faint signs of them gathering towards the pupil.

Under the constant impact of the Eye Power, Shiraha actually felt tired.

Since he was promoted to a first-level Spirit Summoning Warlock and began practicing Arcane Martial Arts, he had never felt tired even after fighting Kushina for a day and a night. But now he felt a very obvious sense of fatigue.

This is a feeling of fatigue from the soul.

However, soon, Shiraha felt the power of the Rinnegan begin to flow into his soul.

[An extraordinary biological eyeball has been detected; the probability of it being Super Radiation Creature biological level is 97%; the probability of it being Mythological Creature biological level is 3%; the energy contained in the current biological eyeball is close to the source of the main bloodline, and after absorption, the probability of bloodline purity increasing is 73%, the probability of bloodline purity degrading is 9%, and the probability of bloodline mutation is 18%]

The information displayed by the "Super Brain Deduction" spell gave Shiraha certainty, and before he could even make a choice, the Eye Power of the Rinnegan began to merge into his soul.

These surging Eye Power contain Energy Particles that are highly compatible with Shiraha.

However, Shiraha quickly stopped absorbing the Eye Power, because the data from the "Eye of Truth" shocked him.

[Bloodline: World Tree Companion Serpent, Fourth-Level (White Phosphorus Serpent, Half Fourth-Level + Divine Tree, Half Fourth-Level); Bloodline Purity 78.6%, Quality "Excellent"]

Lifespan: 840-1050 years

The bloodline and lifespan data displayed by the "Eye of Truth" have shown significant changes.

In such a short time, his bloodline purity rose from 74.5% to 78.6%.

Back then, Shiraha spent several years trying to improve the bloodline purity of Third Level creature, even if it was only by 1%.

In such a short period of time, his bloodline purity increased by 4.1%!

However, just like when he absorbed the Energy Particles from the "star" before, this time, Shiraha's lifespan decreased by nearly 100 years.

Of course, gaining a significant increase in bloodline purity by 100 years of lifespan is definitely a good deal. Last time, when absorbing Energy Particles from the "star", it took 50 years of lifespan to get a 1.5% increase in bloodline purity.

"Like the 'Star,' the Rinnegan contains Energy Particles that are harmful to my body. Although they share the same origin, they can never perfectly merge. Is it because I am not a direct descendant of the Sage of Six Paths?"

After Shiraha stopped absorbing the Eye Power, he immediately felt the impact of the Rinnegan's Eye Power. As expected, it was not something he could easily control.

Therefore, Shiraha controlled his soul to leave the body of the Wood Spirit Avatar "Uchiha Issei" and return to his original body.

After returning to his original body, Shiraha quickly felt a warm sensation throughout his body. A sense of satisfaction from the depths of his bloodline filled his mind and body. He already knew about the influence of bloodline power on the soul. It seemed that the soul could also nourish the physical body, which was something he had not thought of before.

"Is this about to awaken his Sharingan?!" At this moment, after his soul returned to his body, Shiraha noticed the change in the right eye of the Wood Spirit Avatar "Uchiha Issei". The Eye Power was converging towards his right eye, Three-Tomoe Sharingan seemed to be evolving.

"Indeed, besides the pain of losing loved ones, there is an even more direct way to evolve: directly absorbing power of the same origin."

Shiraha realized what was happening.

After just one night, the right eye of the Wood Spirit Avatar "Uchiha Issei" remained unchanged.

He yawned, walked out of the lab, and headed home. He was really sleepy this time and needed to rest.

At noon, Shiraha had only slept for a few hours when he woke up under Kushina's gentle caress.

Shiraha opened his sleepy eyes and asked, "Kushina, what's wrong?"

"A ninja named Kodama has come from outside the clan's territory. He says he's here as a representative of the Akatsuki to see you. He's very strong," Kushina said succinctly.

She felt that Kodama was very strong, but not as strong as Nagato. The reason she came to inform Shiraha was because Kodama was very polite. At the same time, she was not sure of the true strength of the Akatsuki, so she would negotiate rather than resort to violence at the beginning, especially knowing that Nagato was a descendant of the Uzumaki Clan. Kushina did not want to push things to the extreme.

Anyway, Shiraha is at home now, so she's happy to leave this kind of thing to Shiraha.

"Let him in. I'll handle this," Shiraha nodded.

So far, only he himself knows his true identity. Although Kushina is the person he trusts the most and even knows his identity Wizard transmigrator, couples still need to have some privacy.

If you know everything perfectly well, then it's no fun.

This is similar to how Shiraha secretly saved money before getting married. Back then Kushina gave him more money, but Shiraha still saved it himself, finding it a kind of fun.

Unfortunately, after marriage, he became the one earning money, and this joy gradually disappeared.

Kushina picked up Shiraha's clothes and gently helped him put them on.

Shiraha then brought the "Kodama" to the underground experiment.

Seeing that "Uchiha Issei" still hadn't evolved his right eye, Shiraha removed Nagato's other Rinnegan and began transplanting it into "Kodama".

Outside the Uzumaki Clan grounds.

Obito and Black Zetsu, along with tens of thousands of White Zetsu, were poised to attack.

They need to wait for the outcome of the negotiations between "Kodama" and Shiraha.

PS: I'll delete the leave request after I finish updating it in the next few days.
