"Alright, now slowly open your eyes. Don't relax your control of the aura. What does it feel like?" Looking at the two, Takeru continued.
"It feels like being inside a special warm current." Hearing this, Naofumi quickly spoke.
"Yes, like wearing an extra layer of weightless clothing." L'arc said seriously.
"Good. You need to maintain this state at all times. Once you're used to it, you can even use Ten while sleeping." Takeru continued to explain.
"We understand." Hearing Takeru say this, the two nodded seriously.
"Now, feel the Nen I release again." Then, Takeru continued. He again released a powerful Aura pressure. Glass and the others, who had just come out, looked with surprise towards Takeru and the others.
Just looking at Takeru made them feel uncomfortable. They instinctively felt fear, as if Takeru might attack them at any moment.
"This is…!" Feeling the special fluctuation emanating from Takeru, Yui was stunned.
"Yui, do you know what Takeru and the others are doing?" Hearing Yui's words, Therese asked nervously.
"Yes. Takeru is probably teaching them a new ability, [Nen]." Hearing this, Yui spoke directly.
"Nen?" As expected, hearing Yui's words, Glass and the others were confused.
"So sneaky! Master promised to teach Filo too!" Hearing Yui's words, Filo exclaimed excitedly.
"Wait, Filo-chan, don't get agitated. Takeru-sama definitely has his reasons." Seeing Filo's agitation, Melty quickly stopped her.
"Ugh." Hearing Melty's words, Filo puffed out her cheeks, looking a bit unhappy.
Glass and the others were still confused. After all, they still didn't know what Nen was.
"The power to freely manipulate life energy emitted from the body, used in attack or defense, is called Nen." Looking at the confused Glass and the others, Beatrice explained briefly.
"Life energy?!" Hearing this, although they still weren't entirely clear, they seemed to understand a bit.
"If it's life energy, wouldn't continuous use harm the body?" Soon, Glass thought of something and asked curiously.
"If uncontrolled, naturally there is a risk to life. But with proper control, slowing the natural loss of life energy can actually allow one to live longer than ordinary people, while also better maintaining one's strength."
"Also, consumption in ordinary battles is not a problem. The consumed energy can also recover naturally with rest." Looking at the puzzled Glass, Ram spoke directly.
"I see. So Ram-san and the others all know how to use Nen?" Thinking this, Kizuna asked curiously.
"Yes." Hearing Kizuna's question, Ram nodded calmly.
Over with Naofumi and L'arc, with their Nen activated, facing Takeru's malicious intent again, they resisted much better, though still somewhat uncomfortable.
"Alright. You've basically learned Ten. Now you just need to practice diligently to control it better." Looking at the two, Takeru said softly.
"Yes, thank you!" Hearing Takeru's words, the two shouted excitedly.
With Nen activated, they felt they had already undergone some changes. Tomorrow, they would experience firsthand how much stronger they had become.
"Um, Takeru, can you teach us too?" At this moment, Kizuna and the others came to Takeru's side, looking at him expectantly.
Besides Kizuna, Glass, Therese, and even Raphtalia and Rifana had longing in their eyes. Yui and Mio were also curious. They didn't know that Nen was an ability one could learn so simply.
"Alright, since you all want to learn, learn together. Yui, Mio, do you want to learn too?" Looking at the women's pleading eyes, Takeru shook his head helplessly, then looked at Yui and Mio.
"Can we?" Hearing Takeru's words, Yui and Mio asked with surprise.
"Of course. Then, Ram and Beatrice, could I trouble you to first explain Nen to them?" After nodding, Takeru looked at Ram and Beatrice.
"Yes." Hearing Takeru needed help, the two naturally had no problem and nodded directly.
Then, the two quickly explained the concept of Nen to everyone. Of course, since they hadn't activated Nen yet, they focused on the application of Ten.
Soon, everyone had a clearer understanding of Nen. Takeru began to prepare to activate their Nen.
First were Yui and Mio. Among those present, besides Takeru, Ram, and the others, Yui and Mio were the strongest.
Also, they were often trained by Takeru and had great experience in controlling energy.
Soon, as time passed, Takeru skillfully opened their Aura Nodes. Their Aura began to circulate. Then, in just over two minutes, they easily wrapped their Aura around themselves, successfully completing Ten.
After having them maintain that state and gradually experience it, Takeru went to Glass and Kizuna. He also successfully activated their Nen.
The two took about seven or eight minutes to properly wrap their Aura. Next were the excited Filo and Therese.
Neither had any accidents. Only Filo's released Aura surprised everyone a bit. It was more than twice that of Glass and the others.
Finally, Raphtalia and Rifana. The two also wrapped their aura within five minutes. Their Aura volume was also not weak.
As for Koyuki, Emilie, and Melty, they did not participate. Mainly because their control over their own mana was still too unfamiliar. Takeru was worried they wouldn't be able to control their Nen properly, so he didn't activate it for them.
Although Melty was a bit unwilling, she couldn't say much. It was her own problem. If she couldn't control it, she could lose her life. That was no joke.
After handling this, the next step was the training of the four major principles of Nen. Beatrice and Ram could handle that. Takeru disappeared from the spot and went directly into his portable space.
Once inside, Takeru directly took out a large box. From the box, he took out the Sun Breathing Inheritance Scroll. Then, he stored the box back in his item bar.
Looking at the special scroll before him, Takeru didn't hesitate. He directly opened and used the Sun Breathing scroll.
Instantly, a flood of memories poured into Takeru's mind. Along with the memories, a scorching energy physically transformed and strengthened him.
About ten minutes later, Takeru had fully absorbed the Breathing Technique and sword techniques of Sun Breathing.
Looking at his attribute panel, Sun Breathing had directly reached Intermediate.
After slightly adjusting his breathing frequency, Takeru felt his strength seemed to increase again. At the same time, holding the long sword in his hand, he felt an urge to practice swordplay.
Sensing the peaceful atmosphere in the portable space, Takeru didn't want to damage it with his sword dancing. So, he directly disappeared from the spot, returned to the outside world, and flew out over the sea. Reaching the center, Takeru quickly began to move.
"Sun Breathing: First Form, Dance." Speaking softly, Takeru swung his sword.
As he swung, the long sword burst into blazing flames. With the arc of his swing, a scorching sword energy flew forward. The terrifying temperature caused a large amount of water vapor to rise from the sea surface.
Some fish near the surface were subjected to special pressure and burning, fainting dead and floating to the surface.
Seeing the damage from his casual attack, Takeru felt a bit helpless. At the same time, he was somewhat surprised that the Breathing Technique was not weak. Especially in the hands of a strong person, the power it exerted was vastly different.
With that single swing, Takeru had already greatly restrained his power, yet it still caused such a commotion.
Thinking this, Takeru directly used his freezing ability to completely freeze his position. He also set up defensive barriers around the area.
Then, Takeru again reduced his power and quickly moved.
"First Form, Dance! Second Form, Clear Blue Sky! Third Form, Raging Sun! Fourth Form, Burning Bones, Summer Sun..."
Swinging continuously with the Sun Breathing's sword techniques, within just a few minutes, Takeru had quickly performed the twelve forms dozens of times, cycling through them to form the Thirteenth Form.
