"Hmmm…" Kane gave it a thought. "Honestly, only two of them are truly necessary. The rest, I can teach you without them. They're more optimizing training equipment."

He turned towards Rui. "What you truly need are the Parymethia gas masks and the Franmulth drug system."

"What?" Rui raised an eyebrow. He did not like the sound of those.

It wasn't that he hadn't undergone training regimes that required special esoteric substances, it was just that he hadn't expected it for the Godspeed technique.

"What kind of substances and what's their purpose?"

"The Parymethia gas masks are necessary to help you train the weight expulsion method and the Franmulth drug system is necessary to help you train the accelerating of power generation and consumption of your body for the greater speed," Kane mentioned.

"Is it possible to train the Godspeed technique without the training equipment?" Rui wondered.

"Technically, it's possible to train all techniques without their training equipment, it's just way harder because these training systems make use of sophisticated esoteric technology to help you master them faster," Kane pointed. "In this case though, I wouldn't recommend it, I have no idea how long it will take you to even reach the level that you seek to reach without the training equipment, definitely won't happen within a short amount of time."

"Hm," Rui nodded. "Makes sense. But if training equipment is needed for the most important parts of the technique, then why even begin the training?"

After all, what were they supposed to do without the training equipment? Content is property © .

"The training equipment is not needed for all stages of the training, especially not the earliest training stages," Kane told him. "You first need to master a breathing technique and learn how to apply it in combat."

"A breathing technique?" Rui raised an eyebrow. "What for?"

"It's the breathing technique with which you will eventually use to expel mass and to speed up your energy consumption and generation for the extra power to become faster," Kane explained. "Once you've mastered the breathing style and are able to use it consecutively with the movements that you specifically want to apply the boost in speed too."

"Movements that I want to apply the speed boost to?" Rui raised an eyebrow. "You mean that you cannot simply apply the speed boosts to all kinds of movements freely?"

"I did tell you that your reaction and processing speed will lag behind your movement speed, right?" Kane reminded him. "You need to build a certain degree of muscle memory of using the speed amplification of Godspeed with whatever movements you want to use them with. If you plan to use Godspeed with a straightforward bullrush, you need to memorize the timings of the technique by reflex. Because the movement speed is so much faster than your reaction speed, you won't have time for active coordination."

"I see…" Rui frowned. "I plan to use it as a general speed boost for all movements, so that means…"

"You need to master timing that breathing technique with all movements with your muscle memory alone," Kane confirmed. "It's usually because of that it's the norm to apply it to a handful of movements like I do. For example, I have mastered applying Godspeed breathing technique to bullrushes, thus when I do use Godspeed to amplify my speed, I amplify a charge."

Rui nodded. He did recall Kane always using Godspeed to cross distances between him and his opponents to land a strong strike.

"If you want to use Godspeed to amplify the speed of all movements that you make in combat, then you're in for an even rougher time than I was," Kane threw an expression of pity towards Rui. "It's extremely difficult. Normally I'd say it takes too long, but your growth rate and speed of mastery have always been spectacular, so who knows, you may be able to pull off what I wasn't able to, at least, with a diluted version of the Godspeed technique."

Rui appreciated the optimism, but it only made him realize how difficult the venture he was seeking to go out on was.

"Alright, let's get started with the breathing technique," Rui told Kane.

Kane nodded. "It's best we came out here rather than did this in the inn since the breathing can be disruptive to the environment."

Rui nodded.

A normal person's breathing was, of course, unproblematic. However, that wasn't the case when Martial Squires. Their breathing was so powerful that normal people could even die to them just breathing at full power with breathing techniques.

"The breathing technique places a great amount of emphasis on the quality of exhalation," Kane explained. "After all, it is the manner by which you will be expelling mass to increase mass."

Rui nodded, absorbing everything Kane conveyed.

"Of course, as you are currently, you won't be able to expel any mass," Kane continued. "But that's fine, the point is to get you to memorize the form and learn to use it with your movements. Once you have that down, you can start training with the two training equipment and resources that I mentioned earlier, they will help you actually master the ability to expel mass via breathing and to be able to use it to trigger higher energy consumption and dispel mass using the breathing technique."

He inhaled deeply, holding his breath for a moment, before suddenly exhaling.

BANG!

Rui's eyes widened as Kane's forceful exhalation sounded like a heavy-caliber gunshot. Given how heavy his breath was, it was not actually far from the truth at all.

"That was strong," Rui murmured. "Is that what it's like?"

"That was just one breath of the technique, yes," Kane nodded. "You have to do this in rapid succession and only then can you possibly be able to actually trigger the Godspeed technique."

"I see," Rui nodded. "Well, let's get this out of the way."

Rui was eager to master the breathing technique. He had just learned that the road ahead of him was going to be tougher than he had expected, but he was up for a challenge.
