Chapter 148, Demon Bud Technique and Senjutsu.
"Is this place okay?"
Hiruko brought Raijin and Tsunade to a laboratory.
Although it's called a laboratory, there's actually nothing inside. There's a bed for resting, and another bed that clearly isn't for resting.
And there's a desk for writing, and another desk that clearly isn't for writing.
"I don't know what you'll need for your experiments yet, so there's nothing here now. Once you have a direction for your experiments, you can write an application form and give it to me. The village will deliver it then."
Hiruko casually sat on the bed that clearly wasn't for resting and said to Raijin.
"Yes, what we have now is enough. After all, we don't have a clear direction yet."
Raijin nodded in response and sat on the bed for resting with Tsunade.
"So, can I understand what Senjutsu is? If possible, I might be able to provide some help to you."
Hiruko licked his lips and asked Raijin a question.
Despite gaining the favor of the Hokage, Hiruko couldn't suppress his desire to prove his worth.
"It's a technique that channels natural energy into the body and merging it with our chakra. We call it Sage Mode. The next step is to use natural energy to permanently enhance the body," Raijin explained to Hiruko.
In fact, permanent Senjutsu and the Demon Buds Technique share some similarities.
At their core, both involve taking power from an external source.
Permanent Senjutsu takes power from nature.
The Demon Buds Technique takes power from other living beings.
But both aim to use that power to strengthen the user.
"Natural energy?"
Hiruko was surprised. This was a type of energy he had never heard of before.
"That's right," Raijin confirmed, sharing information about Senjutsu with Hiruko. Since Senju Tobirama had said they could discuss it with Hiruko, it meant he was trustworthy. Additionally, the similarities between the Demon Buds Technique and Senjutsu indicated that Hiruko's research could be beneficial to Raijin.
Moreover, Senjutsu wasn't something that could be mastered easily. It took Raijin a year and a half just to sense natural energy.
"Can this energy really fuse with the body?" Hiruko asked Raijin.
Hiruko didn't question the existence of this energy. He was naturally low on chakra, making his path to becoming a ninja much more challenging than for most people.
It wasn't that Hiruko lacked intelligence.
In fact, the creation of the Demon Buds Technique proved his high intelligence. He was a scientific talent who could even rival Orochimaru.
If natural energy didn't exist, the Hokage wouldn't personally bring Raijin and Tsunade here to develop it.
Even if Tsunade was the Hokage's granddaughter, that wouldn't matter.
Given Raijin and Tsunade's abilities, they wouldn't waste time developing an uncertain technique.
Hiruko just wanted to confirm if this natural energy could fully merge with a living being.
Verifying this was a significant challenge.
"Based on current information, we can confirm that natural energy can merge with the body, extending lifespan, enhancing intelligence, and boosting strength. Some beings have lived for over a thousand years thanks to it," Raijin explained to Hiruko.
"That's truly an incredible technique," Hiruko said after a moment of thought.
"I feel that permanent Senjutsu and the Demon Buds Technique share similarities, especially in the final stage of merging natural energy with the body," Hiruko observed.
"Exactly. So, Hiruko-sensei, do you have any progress in this area?"
Raijin asked.
"I wouldn't dare call myself a sensei, but I have made some progress," Hiruko replied, waving his hands modestly.
"The main issue I'm facing is how to merge the stolen energy with my own body," Hiruko explained his thoughts to Raijin and Tsunade.
As Hiruko elaborated, Raijin's brow furrowed.
He realized the fundamental difference between Senjutsu and the Demon Buds Technique.
Natural energy is pure energy, while the Demon Buds Technique involves taking something that isn't purely energy.
Raijin wasn't sure what the final form of the Demon Buds Technique would be.
For now, Hiruko's experiments were still at the stage of merging flesh and blood.
The research materials were not exactly crucial for Raijin, but they were better than nothing.
"What a great concept."
As Hiruko's explanation gradually came to an end, Raijin timely praised.
Regardless of whether Hiruko's achievements were helpful to him, since Hiruko was willing to share, some praise was naturally due.
"If possible, I think I need a monkey," Raijin said to Hiruko.
Monkeys, mammals, their physical data and other aspects are not much different from humans. Therefore, if you want to develop permanent Senjutsu, the most suitable creature is a monkey.
"Okay, it will be sent to you soon."
Upon hearing this, Hiruko nodded and stood up.
"You two rest here, I hope my materials can help you."
"Um, I benefited a lot from your explanation," Raijin also stood up and said to Hiruko.
"Um."
Hiruko chuckled, nodded, and left.
In fact, it was through Hiruko's explanation that he gradually realized that his current research results seemed to be of little help to Raijin...
Watching Hiruko leave, Raijin let out a sigh.
"I thought it would be somewhat useful."
Tsunade raised her eyebrows and said to Raijin.
"Who would disagree? But Hiruko, he seems quite enthusiastic."
Raijin came to Tsunade's side, it was surprising that he could tell his research results to a person he just met, even with the existence of Senju Tobirama.
