It was clear that Rasa's so-called "Breathing Technique" was inspired by another anime he had seen in his previous life—Demon Slayer: Kimetsu no Yaiba. To some extent, this method of training was quite reliable, akin to aerobic exercises in fitness training.
As for why Rasa had revealed the existence of Senjutsu energy and this place to so many people, it was because he needed to strengthen the faction capable of using Senjutsu energy.
The more people who could use Senjutsu energy, the less resistance he would face when the time came to convert all the world's Senjutsu energy into chakra.
Hearing this, everyone present understood Rasa's intentions.
"Is this similar to Konoha's Eight Gates?"
Michikawa asked, seeking clarification.
"Yes, but as you've all trained in the Eight Gates, you know its entry barrier is quite high, and the side effects are severe. What I need is a taijutsu technique that's suitable for all ages, with minimal side effects and a low entry barrier. Of course, the advanced stages can be more challenging, but the basics must be accessible to everyone. My goal is to improve the overall potential of Sunagakure's citizens to some extent."
Everyone nodded, finally grasping Rasa's vision.
"From now on, all of you are free to come here to train at any time. However, secrecy is paramount. This place cannot be exposed to too many people yet. Additionally..."
Rasa glanced back at the forest and warned,
"The depths of the forest are off-limits unless you have my explicit permission or are accompanied by Bunpuku-sama. He will explain the rules to you and will remain here to oversee things."
Ebizō, connecting the dots, asked,
"So, Kazekage-sama, when you asked me to develop a large-scale barrier technique, was it to protect this place?"
"Yes and no," Rasa explained.
"That's one of the reasons. The other is that, as you've likely noticed, with more people joining Sunagakure, our current land is no longer sufficient. In the future, Sunagakure will inevitably expand. As Senjutsu energy continues to transform this desert, more habitable areas will emerge. When the time comes to relocate the village, we'll lose the natural protection of the terrain, and barriers will become our only defense."
The group was surprised by how far ahead Rasa was thinking.
"I understand. For the future of the village, I'll do everything in my power to develop the barrier technique you need."
Ebizō declared.
"There's no need to push yourself to the brink, Elder. With Honoka's assistance, it should be easier than you think. Honoka, you'll also need to work hard. You can discuss the Reverse Summoning Technique with Ebizō-sama. Once everything is ready, I plan to connect this place to the Forgotten Island."
"Forgotten Island? What's that?"
The sudden mention of this name piqued everyone's curiosity.
Rasa began to explain.
"That is an island inhabited by many giant creatures. It was also the main reason I left the village this time. The creatures there are highly suitable for summoning contracts. However, the island is too far away. The best way to control it is to use the Reverse Summoning Technique to create a spatial passage. While these creatures may not compare to the Three Great Sage Regions, they are more than enough to address Sunagakure's lack of powerful summoning creatures."
Everyone was amazed by this revelation. It seemed that Rasa, as the Kazekage, had been doing far more than they had imagined. In comparison, the village's high-ranking officials and elders felt as though they had been slacking off, contributing little.
Seeing this, Chiyo took the initiative to speak up.
"I understand. Leave it to me. I'll quickly familiarize myself with this energy and develop the corresponding techniques. However, I'll need you to explain the characteristics of this Senjutsu energy, Kazekage-sama. Otherwise, without the ability to sense it, this old woman would be completely lost."
"Of course."
Rasa breathed a sigh of relief seeing Chiyo take on the task so proactively.
When it came to developing techniques, Chiyo was undoubtedly the most talented in the village. While Pakura was also highly gifted, she was still too young.
Technique development required not only inspiration but also accumulated wisdom.
Chiyo's words also ignited the curiosity of the others, who were eager to learn just how powerful this so-called Senjutsu energy was.
Rasa didn't hold back. After gaining the power of Mōryō, the abilities he was about to demonstrate could no longer be considered his trump cards.
"Follow me."
He wasn't foolish enough to destroy the newly formed forest just to showcase his power. He walked a few steps to the edge of the forest, where the desert began. The others followed curiously.
Once they were in a suitable location, Rasa stopped and turned to face the group, ready to explain Senjutsu energy.
"First, the most basic characteristic of Senjutsu energy is its powerful life force."
As he spoke, Rasa pulled out a kunai from his pocket and made a shallow cut on his palm. He held it up for everyone to see, and to their astonishment, the wound healed visibly before their eyes.
"Essentially, this is the result of using Senjutsu energy to activate and enhance the body's natural healing abilities. However, unlike the Star Release chakra I once gave you, which consumes the energy within your cells and places a burden on your body, Senjutsu energy is different. This energy comes from nature itself. Not only does it not burden you, but its life force also enhances your recovery, reduces fatigue, and boosts your physical stamina."
With that, Rasa extended his hand and walked up to each person, infusing them with a small amount of Senjutsu energy.
Aside from Pakura, who had experienced the power of Senjutsu energy before, the others were stunned. They felt as though they had just woken up from a deep, restful sleep. Their bodies were filled with energy, their spirits invigorated, and it seemed as though old ailments had been healed, making them feel years younger.
"So this is Senjutsu energy? This life force is truly incredible!"
Chiyo exclaimed in awe.
Michikawa clenched his fist, equally amazed.
"With this power, we can finally discard Star Release chakra."
"Exactly."
Rasa nodded.
"Once you master Senjutsu energy, Star Release chakra will indeed become obsolete. Using Senjutsu energy to train in the Eight Gates will no longer place such a heavy burden on your bodies."
As Rasa spoke, his gaze shifted to Pakura, who blushed slightly, clearly recalling Rasa's earlier concern for her.
"Now, for the second point. Like Star Release chakra, Senjutsu energy is fundamentally a force that activates and enhances the body. This means it can significantly boost your taijutsu. I won't demonstrate this here. As for its effects on ninjutsu, I haven't tested that yet. That's something you'll need to explore."
Rasa then decided to hover to next point.
"Having covered the basic characteristics of Senjutsu energy, let's move on to some of its abilities. The first one I'll introduce is called: Material Transformation..."
With that, Rasa clasped his hands together, and Senjutsu energy surged within him.
"Four Pillar House Technique..."
