Compared to the more powerful conceptual equipment, Kanae was obviously more interested in the Breathing technique Ryuga mentioned.
Magic was something Kanae had tried - after purchasing the commodity, she could indeed successfully extract mana, but the same technique couldn't be taught to others.
Whether it was her sister Shinobu, Kanao, or the other Pillars, none could master this power.
At that time, Tohsaka Rin had helped investigate this point, and the final conclusion was that humans in each world had different constitutions.
But Breathing techniques were different - skills improved based on the original Flame Breathing would certainly be very compatible with human physiology in her world.
In other words, this power was very likely teachable to others.
If her power alone was insufficient to slay the Demon King Muzan Kibutsuji, then all the Pillars working together wholeheartedly might be able to create a miracle.
Regarding Kanae's thoughts, Ryuga could guess them with his eyes closed.
So he didn't waste any words and directly uploaded the skills he had comprehended.
[Ryuga: "I've uploaded all the previously comprehended skills to the store - check them out yourself!"]
With these words, everyone immediately opened the group store interface.
Then they saw four new products all at once.
[Kanae: "Water, Fire, Wind, Thunder, Earth - the Five Elements Breathing Technique actually includes all the basic schools, and even possesses techniques from the long-lost source of all Breathing - Sun Breathing?"]
[Kanae: "How is this possible! Lord Ryuga only purchased Flame Breathing, didn't he?"]
After reading the product descriptions, Kanae was completely stunned.
Compared to existing schools, the legendary Sun Breathing was the true power capable of restraining demons.
Unfortunately, Sun Breathing had long been lost, and no one could master this power anymore.
She never expected it to reappear here at this moment.
Regarding Kanae's surprise, before Ryuga could say anything, Erica shrugged.
[Erica: "It's just drawing inferences from one example - is this really surprising for Lord Ryuga?"]
With just one magical technique, Ryuga had almost mastered an entire conceptual equipment system of magic.
Compared to this performance, merely reverse-engineering an entire system through one Breathing technique wasn't worth being surprised about.
The Breathing technique system was much simpler than the equipment system.
[Kanae: "You're right."]
After taking a deep breath, Kanae calmed down.
To say something disrespectful, even the genius who could create Sun Breathing probably couldn't compare to Lord Ryuga in any way. It was natural for Ryuga to reverse-engineer the entire system.
At this time, Ryuga also provided a simple explanation.
[Ryuga: "I merely used Flame Breathing to reverse-engineer and restore Sun Breathing, then successfully deduced the other types of Breathing techniques."]
[Ryuga: "Water, Fire, Wind, Thunder, Earth - these five Breathing techniques are actually inferior versions compared to pure Sun Breathing. However, people with insufficient life force aren't suitable for traditional Sun Breathing - forcing its use will inevitably consume one's lifespan."]
[Ryuga: "To lower the threshold, I designed the Five Elements Breathing Technique, preserving Sun Breathing's lethality while greatly reducing the drawback of life force consumption."]
[Ryuga: "Although the upper limit isn't high, as a combat-type skill, it should suffice."]
Hearing Ryuga's words, Tohsaka Rin, who had also finished reading the product descriptions, tilted her head with big question marks appearing above it.
[Tohsaka Rin: "Upper limit isn't high?"]
[Tohsaka Rin: "Lord Ryuga calls this kind of power - priced at ten thousand points and capable of reaching Second Order strength - having a low upper limit?"]
Second Order level strength, whether in the Campione world or her TYPE-MOON world, could already be called the pinnacle of humanity.
Even Crown-designated mages from the Clock Tower might not possess this level of combat capability.
How did it seem somewhat despised in Ryuga's words?
Hearing Tohsaka Rin's words, Kanae, who had been overjoyed, suddenly stiffened.
Wait, how much did it cost again?
Meanwhile, hearing Tohsaka Rin's question, Ryuga shook his head and explained.
[Ryuga: "I said the upper limit isn't high because the entire Sun Breathing system's architectural framework has fundamental problems."]
[Ryuga: "Power that can only consume life force but cannot replenish it has problems at its source design. If based on the existing structure, ordinary practitioners' limits are essentially fixed."]
Sun Breathing was a technique created by Yoriichi Tsugikuni, its core essentially helping someone with exceptional life force talent to squander their excess vitality.
For Yoriichi Tsugikuni, with his abnormal constitution, Sun Breathing was naturally no problem.
But for other ordinary people, they simply couldn't bear this power and consumption, naturally only able to create derivative schools suitable for themselves.
However, no matter how they derived and improved, they couldn't change the fact that consumption exceeded replenishment.
In the Demon Slayer world, this Breathing technique might have positive meaning, but for Ryuga, this was definitely not a path to becoming stronger.
It could be used as a technique, but not practiced as a method.
[Ryuga: "So I completely overthrew Sun Breathing and recreated a cultivation method with life nurturing as its core."]
[Tohsaka Rin: "Are you referring to this Pure Yang Cultivation Method?"]
[Ryuga: "Correct."]
[Ryuga: "I recommend using Pure Yang Cultivation Method as the foundation and Five Elements Breathing Technique as application - this way you can increase your life force and elevate your life level."]
Pure Yang Cultivation Method focused on life nurturing, Five Elements Breathing Technique focused on combat.
Increasing life force would greatly help both physical enhancement and total mana enhancement.
With Tohsaka Rin's intelligence, she naturally immediately understood the Pure Yang Cultivation Method's advantages.
Compared to skills that consumed life force and mana, cultivation methods that could improve one's physical limits were true treasures!
Just like immortal cultivation techniques in manga.
If placed elsewhere, this could be called a closely guarded secret!
Extremely excited, she immediately opened the [Pure Yang Cultivation Method] product interface.
However, the moment she saw the price, she froze as well.
"Ah?"
