Tsunade had always been decisive. She immediately opened the Summoning Storage Scroll and took out some medicinal ingredients and extraction equipment.
After extracting the essences from all the medicinal ingredients, she held out her hand.
A large amount of Yang Release Chakra surged into the medicinal essence.
But she quickly discovered a problem.
There was a limit to how much Yang Release Chakra the medicinal essence could contain.
Once Tsunade could no longer pour in any Yang Release Chakra, she withdrew her hand.
"About one-tenth of the Chakra required for the Mystical Palm Technique was infused."
Orochimaru assessed.
The Mystical Palm Technique was an A-rank Medical Ninjutsu. It was extremely difficult to learn, and anyone who mastered it could be called a Medical Jonin.
Its effects were also comprehensive, capable of treating most internal and external injuries.
Only injuries such as missing limbs, near-death conditions, or extensive organ damage were beyond its ability.
"At one-tenth the effect of the Mystical Palm Technique, it may be stronger than the Blue Healing Potion, but only by a limited amount."
Tsunade sighed.
"If it is only slightly stronger than the Blue Healing Potion, then it cannot be widely promoted."
Orochimaru shook his head. "Its cost is far higher. Widespread use would not be worth it."
"Mm."
Tsunade agreed.
"But the limit of how much Yang Release Chakra the medicinal essence can contain is fixed. It will be difficult to increase."
Orochimaru frowned.
"Then is there some item capable of containing a large amount of Yang Release Chakra?"
Natsuki asked at the right moment.
Tsunade instinctively lowered her head.
Beneath her snow-white skin was a necklace.
It was a relic of Senju Hashirama.
Set within the necklace was a Chakra Crystal containing Senju Hashirama's Chakra.
"A Chakra Crystal would work."
Orochimaru immediately thought of the Chakra Crystal as well. "But it is far too rare. There is only one in all of Konoha."
As its name suggested, a Chakra Crystal was Chakra condensed into a tangible crystal.
It was rare because, apart from Senju Hashirama, it was difficult to find a second ninja with that much Chakra.
Not only could Hiruzen Sarutobi, Orochimaru, and the others not accomplish it, even Senju Tobirama would have found it difficult.
Orochimaru suddenly paused.
He thought of an item comparable to a Chakra Crystal: Senju Hashirama's cells.
He had participated in the Hashirama Cells experiments overseen by Hiruzen Sarutobi back then.
After learning about Hashirama Cells at the time, he had been deeply shocked.
He could not understand why, after a person had been dead for so long, his cells had not died. Instead, they possessed terrifying vitality.
It was that vitality that gave Konoha the idea of creating artificial Wood Release ninja.
Simply put, they transplanted Hashirama Cells into ninja.
But vitality was both their success and their failure.
The Hashirama Cells' seemingly living nature clashed violently with other people's bodies, resulting in no survivors.
What if Hashirama Cells were placed into the medicinal essence?
The medicinal essence was not human, so in theory, it would not conflict with Hashirama Cells.
Moreover, the amount of Hashirama Cells could be controlled. There was no need to use too many as in a transplant; just a tiny amount would be enough.
The only question was whether Uzumaki Mito and Tsunade would agree.
After all, Senju Hashirama was dead. Extracting his Hashirama Cells would be no different from desecrating the dead.
The reason Konoha's Hashirama Cells experiments had been able to proceed back then was also because Uzumaki Mito and Tsunade had agreed.
Hiruzen Sarutobi had only managed to make them reluctantly accept it by invoking the greater good of Konoha.
Could the Red Healing Potion: Blood of God truly achieve such results?
Orochimaru had serious doubts.
"I'll think about what items might work."
Tsunade came back to her senses.
She had not immediately thought of Hashirama Cells, but her thoughts were somewhat similar to Orochimaru's.
If the Red Healing Potion: Blood of God proved effective enough, she could use the Chakra Crystal on the First Hokage's Necklace.
But there was another problem: once the Chakra Crystal was depleted, it would not regenerate.
Still, she could first use the Chakra Crystal to make a single potion and see whether the result was truly worthwhile.
The Chakra Crystal contained quite a bit of Senju Hashirama's Chakra. Making one potion would not cause any significant loss.
There was no need to rush for now. They could see whether they could find a substitute.
"Mm."
Orochimaru nodded. "I'll think about it too."
Hashirama Cells were too special. Unless Tsunade brought them up herself, he would not mention them.
Though Natsuki found it somewhat regrettable, he could guess what Orochimaru was thinking.
If you won't say it, neither will I.
Natsuki ended the discussion with them and ran off to train with Nawaki and Uzumaki Kushina.
The night passed without incident.
The next day, the group continued on their journey.
By dusk, they finally reached the southeastern coast of the Land of Fire.
"It's my first time seeing the sea!"
Nawaki excitedly ran toward the shore.
"There is nothing much to see about the sea."
Uzumaki Kushina spoke without much interest.
The Land of Whirlpools was surrounded by the sea on all sides, so she had seen far too much of it since childhood.
Natsuki had seen the sea in his previous life, but this was his first time seeing it in this life.
Having lived two lives, however, he was not as excited as Nawaki and remained calm.
Tsunade glanced at Natsuki, then at Nawaki, and could not help shaking her head.
Fortunately, there were no enemies nearby. Otherwise, Nawaki's behavior would have been no different from courting death.
He was simply too young and reckless.
In contrast, Natsuki satisfied her greatly.
If he had the same personality as Nawaki, then the future of their squad would be truly worrying.
"Begin carrying out the mission."
After Nawaki returned, Orochimaru spoke. "Unless absolutely necessary, Tsunade and I will not intervene ourselves."
"Kushina, do you know any sensory ninjutsu?"
Natsuki looked at Uzumaki Kushina.
"I do."
Uzumaki Kushina nodded.
Although the Uzumaki Clan excelled most at Sealing Jutsu, their sensory ninjutsu was also formidable.
Mind's Eye of the Kagura was even considered the strongest sensory ninjutsu in the Ninja World, stronger than the Byakugan.
Of course, Uzumaki Kushina did not yet know Mind's Eye of the Kagura.
"Then let's find our target first."
After speaking, Natsuki formed hand seals with both hands and summoned his Summoning Beast, Crow Black Feather.
Nawaki summoned his Ninja Dog, Saburo.
Sea, land, and air—only the sea was missing.
Natsuki felt that he could find a Summoning Beast from the ocean.
However, ocean-dwelling Summoning Beasts were quite rare, and he could not think of any suitable one to form a contract with for the moment.
"Let's take this route."
Natsuki took out a map. "There are plenty of places to hide along this route, and it is not far from the shore."
"A good route."
Tsunade gave it a glance.
Natsuki's group immediately began scouting along their chosen route.
Tsunade and Orochimaru followed them in secret.
But evidently, finding a band of wandering Rogue Ninja was not a simple task.
Bored from following them, Tsunade continued pondering the Red Healing Potion: Blood of God.
Suddenly, her gaze sharpened. Like Orochimaru, she thought of Hashirama Cells.
Hashirama Cells contained an enormous amount of Chakra and perfectly met the requirements.
But... Tsunade hesitated.
