This modification to the Summoning Technique was not actually revolutionary.
It was merely a deep expansion based on the Summoning Technique Genma currently possessed, similar to the previous Lightning Flicker.
Impure World Reincarnation was also a type of Summoning Technique and could summon souls.
There was still quite a gap between it and the Sage of Six Paths' Summoning Technique, which required neither chakra nor biological samples as a medium.
So it only required 3 Setting Value points.
"Tomorrow is my day off. I can use that opportunity to test this technique, then go find Tsunade."
Genma mused to himself.
After spending 3 Setting Value points, he had to squeeze something worthwhile out of Tsunade.
But who should he use as a test subject tomorrow?
The First? The Second Hokage?
Going to dig up graves now—no, going on an archaeological expedition—didn't seem very appropriate.
"But I don't necessarily have to summon a soul first..."
Genma quickly settled on a plan, then closed his eyes and went to sleep.
The night passed without incident.
The next morning, Genma first went into the woods and entered Wood Release Chakra Mode, eating and drinking his fill before heading to Tsunade's home.
Tsunade, Shizune, and Huixiang were all there.
Genma did not beat around the bush and got straight to the point. "Lady Tsunade, I've made a breakthrough with the Summoning Technique. Let's test it now!"
"The Summoning Technique?"
"I'm not interest—"
Tsunade started to speak instinctively, but quickly stopped and fixed her gaze on Genma. "What do you mean?"
Genma said, "I mentioned it last time."
Tsunade abruptly rose to her feet.
Sensing that something was wrong, Shizune quickly asked, "What is it?"
Genma smiled. "I made some changes to the Summoning Technique."
Tsunade interrupted the two in a low voice. "How are we going to test it?"
Genma said, "Let's start with something simple."
"Lady Tsunade, pull out a strand of hair for me. It needs to have the follicle attached."
Tsunade immediately understood. "You only need a biological sample, not a summoning scroll?"
Genma nodded. "I think it'll work."
Tsunade stared at him for two seconds before pulling out a strand of hair.
Taking the hair, Genma retreated into the courtyard.
Tsunade and the other two followed him outside, but Genma stopped them. "Just stand by the door."
Then Genma clasped his hands together, holding Tsunade's strand of hair between his palms.
Summoning Technique!
A technique formed from black runes immediately spread beneath Genma's feet, followed by a bang as smoke erupted.
At nearly the same moment, Tsunade, who had been standing between Shizune and Huixiang, vanished from the doorway.
When the smoke cleared, Tsunade stood before Genma, her presence overwhelmingly oppressive.
Genma took a step back and looked up slightly. "If I have a biological sample or chakra, I'm highly confident that I can summon a soul from the Pure Land."
"Of course, that assumes the soul is in the Pure Land and hasn't been sealed by a Sealing Technique."
"Lady Tsunade, want to give it a try?"
Tsunade's heart trembled, and she suddenly became incredibly nervous. "You... are you sure you can do it?"
Huixiang was still completely confused, but Shizune had already understood. She clenched her fists, looking worriedly at the two ahead of her.
Seeing Tsunade's hesitation and even fear, Genma said seriously, "I'm sure."
"I'm a genius, after all!"
Tsunade drew a deep breath, then said, "Wait here."
With that, she used the Body Flicker Technique and vanished.
Huixiang hesitantly asked, "What's wrong with Lady Tsunade?"
Shizune quietly explained it to Huixiang.
Huixiang listened in astonishment.
She had never expected that Tsunade had lost all her loved ones as well, or that the once-powerful Senju Clan had vanished just like the Uzumaki Clan.
No wonder she had never seen any of Tsunade's relatives after coming to Konoha.
"If only there hadn't been any war."
After hearing it all, Huixiang murmured instinctively.
Meanwhile.
Tsunade rushed to Orochimaru's laboratory at top speed.
Though it was her first time coming here, she moved as though she knew the place well.
Orochimaru was quite surprised by Tsunade's arrival. "Tsunade, it's been a long time. I never expected you to come here."
Tsunade should not have known about this place, but he was not surprised that she had managed to find it.
This was within Konoha. There were no absolute secrets.
Especially not from Tsunade.
She knew Orochimaru too well. Finding someone in Konoha was easy for her.
Staring at Orochimaru, who was busy at work, Tsunade went straight to the point. "You've been researching my grandfather's cells all this time, haven't you?"
Orochimaru stopped what he was doing, turned around, and smiled at Tsunade. "Oh? Have you taken an interest, Tsunade?"
"If you join me, I'm confident we can achieve results quickly."
Tsunade said coldly, "I have no interest in your work."
"Give me a sample of my grandfather's cells."
Orochimaru was puzzled. Was she planning to study them herself?
But he could tell that Tsunade was in a poor mood, so he did not ask further. He smiled and said, "Of course, no problem."
"If you need anything, you can come find me anytime."
As he spoke, Orochimaru walked off to retrieve what Tsunade needed.
Tsunade had arrived suddenly and left just as quickly.
After watching Tsunade leave, Orochimaru suddenly laughed. "It seems something interesting happened that I don't know about!"
He and Danzo had not been the first to experiment with Hashirama Cells.
They had already been researched during the Second Hokage's era.
Later, more than a decade ago, his dear teacher Sarutobi Hiruzen had also conducted large-scale human experiments. In the end, the losses were too severe, forcing him to halt the project and seal it away permanently.
That was why Danzo could only conduct his research in secret.
But did Teacher Sarutobi truly know nothing?
Orochimaru smiled, turned around, and continued working.
At Tsunade's home, Genma could not help staring blankly at the test tube Tsunade handed him.
Senju Hashirama's stem cells?
She hadn't gone to find Nawaki's?
That was a little too filial!
Genma reached out and accepted the test tube, though he knowingly asked, "Whose cells are these?"
Tsunade's expression was complicated. "My grandfather's."
Genma nodded. The moment he opened the test tube, he sensed an immense vitality.
As expected of the First!
Of course, Senju Hashirama had been dead for so long that these could not be ordinary cells. They were stem cells capable of independent replication and division.
So even though Senju Hashirama was dead, it was reasonable for these cells to remain so powerful.
Because they had not been obtained from a corpse, and they were not ordinary cells.
After examining the Hashirama Cells, Genma used Chakra Refinement Technique 1.0 before Tsunade and the others. He combined his spiritual energy with Senju Hashirama's cellular energy, refined it into chakra, and absorbed it into his body.
This gave Genma direct control over Senju Hashirama's biological information.
From now on, he would no longer need a medium to use the Summoning Technique.
Genma took several steps back and clasped his hands together.
Black runes rapidly spread beneath him, forming a technique.
Bang!
Smoke surged upward.
Tsunade's eyes narrowed. "It really worked?"
Shizune and Huixiang grew tense as well, their eyes wide.
The First!
The God of Shinobi!
Alive!
The smoke gradually dispersed.
Senju Hashirama, in a spirit-body state, appeared before them.
"Hm?"
"This is..."
