Naruto: Kurotsuchi Mayuri

"Go call Orochimaru!" Tsunade, feeling a burst of inspiration, slammed her hand on the table, breaking it into pieces, and told Shizune.

Then, she pulled Kagetsu along to discuss the further development of Blood Armor.

Of course, it was mainly Kagetsu presenting his ideas and questions, while Tsunade solved the difficult parts and offered her expertise.

In no time, Tsunade's expertise in medical ninjutsu easily helped Kagetsu solve many of the issues related to the body.

While they were in the midst of their heated discussion, Orochimaru arrived at the Senju compound, led by Shizune, who had been waiting for him. He joined Tsunade and Kagetsu in the courtyard.

As soon as Orochimaru arrived, without much time for small talk, Tsunade pulled him into a seat and into the discussion.

Orochimaru patiently listened to Tsunade's explanation, his snake-like eyes glancing with surprise at Kagetsu, who was sitting nearby.

Even though this technique was still in its early stages and not yet fully developed, the concept alone was enough to impress him. The idea of "Blood Armor," which Kagetsu had suggested, intrigued him even more.

"So, the Blood Armor is divided into two parts.

First, there's the Active Blood Armor. This uses the Eight Gates technique to stimulate excess chakra in the body's Chakra pathways, creating a powerful boost in attack. The intensity can be controlled, minimizing harm to the body.

Second, there's the Passive Blood Armor. This combines the Eight Gates with medical ninjutsu, forming a protective layer over the body's surface and nourishing it.

The Active Blood Armor can be activated when needed, while the Passive Blood Armor, once perfected, can be maintained continuously without interruption.

Did I understand that correctly?" Orochimaru quickly summarized what Tsunade had explained.

"You got it," Tsunade nodded.

"So, what exactly do you need from me?" Orochimaru asked, though it was clear he already understood why Tsunade and Kagetsu had called him here.

Even though he had plenty of his own tasks, the uniqueness of this technique, combined with its growth potential, made him willing to invest some time in it.

Besides, this concept had come from Kagetsu, his own disciple. As his teacher, especially with Tsunade so eager to help, it wasn't in Orochimaru's nature to stand idly by.

"You'll be in charge of the seals and the technique. I'll handle the medical and body-related aspects," Tsunade said enthusiastically, waving her hand.

It wasn't just the excitement of the technique itself that lifted her spirits. She had realized that this technique could help her overcome some obstacles in her own research.

She had been working on these problems alone for a long time. But now, with Kagetsu's ideas and Orochimaru's expertise in techniques and chakra, she felt that the breakthroughs she had been searching for were within reach.

If successful, she might still have her hemophobia, but her ability to defend herself in dangerous situations would greatly increase! 

With her growing strength, it would be much easier for her to leave the village and explore the world.

And so, Tsunade didn't hold anything back. She shared everything she knew about medical ninjutsu, including her own related research.

"The Passive Blood Armor, which involves medical ninjutsu and yang-release chakra, is similar to a technique I'm working on.

I've named it Creation Rebirth! By gathering chakra in a specific area over time, it can be released when needed to stimulate rapid cell regeneration and fully heal wounds. But the downside is that it shortens your lifespan."

The Passive Blood Armor can maintain itself for a long time after being mastered, according to theory. But compared to my Creation Rebirth, it weakens healing abilities while increasing defense!

If Creation Rebirth is a healing-type jutsu that allows me to fight without worrying about injuries, representing a 'shield,' then the other jutsu I want to create is based on monstrous strength, greatly boosting my attack power and representing a 'spear'—that's the Hundred Healings Technique.

I've already created both of these jutsu, and I'm refining them. They can keep me in an immortal state during battle. However, they consume a huge amount of chakra. Even for me, I can only use them as a last resort or when I need to decide the outcome of a fight.

Now, what I want to solve is the issue of the chakra consumption for both of these techniques.

I've ranked Creation Rebirth and the Hundred Healings Technique as S-rank jutsu in terms of difficulty and power. Although the Blood Armor is different from these two, it likely also requires a massive amount of chakra to maintain."

"What an astonishing technique. I thought you, Tsunade, had lost your spirit and had become nothing but a drunk and a gambler. But it turns out you secretly created such powerful jutsu?" 

Orochimaru was equally surprised by the fact that Tsunade had quietly developed two S-rank jutsu. This made him take a fresh look at his teammate, while also feeling a sense of urgency within himself.

Clearly, Tsunade had completely broken through her own power system and walked far along that path. If it weren't for her hemophobia and long absence from battle, she would likely be even harder to deal with now, stronger than ever.

And what about his path? Eternal life and immortality?

Looking at the confident Tsunade, who no longer appeared defeated, Orochimaru reevaluated her and reflected on himself.

Perhaps it was time for him to choose his own future path in ninjutsu.

The Third Hokage's way was becoming less and less suitable for him.

"There are many ways to solve the chakra problem. If you trust me, I can share some of my research results with you. Though they aren't perfect yet," Orochimaru uncharacteristically offered.

But Tsunade shook her head, "Of course, you can share, but you don't need to give me all of your research. I already have a prototype idea in mind.

I have a feeling that once I complete the Blood Armor, my prototype technique will also come to fruition."

"Suit yourself. But I should still thank you. I didn't expect you'd be willing to get involved in something as troublesome as this," Orochimaru said softly.

He genuinely hadn't expected Tsunade to involve herself in something like this.

"You paid me, didn't you? Besides, as his half-teacher, isn't it my job to help solve his problems?" Tsunade snorted, crossing her arms.

The three of them immersed themselves once again in discussing and researching the creation of the technique.

Kagetsu provided the requirements and ideas. Orochimaru handled the technique and chakra issues, while Tsunade focused on the body's Tenketsu and Chakra pathway System, and connecting Kagetsu and Orochimaru's ideas. 

She evaluated their suggestions based on her understanding of the human body to determine whether their ideas were feasible.

If an idea was feasible, they would continue to explore it. If not, they would reject it and find another approach.

Unconsciously, time passed little by little amidst their debates and the sparks of inspiration.

The three of them were so engrossed that they talked all night long. When the Nara clan members came looking for them and saw this scene, they were taken aback. They could only quietly leave as quietly as they had come.
