This sword technique demands a high level of explosive power from the legs, hence the "Lightning Flash" is indeed the most rudimentary form of the Thunder Breathing, yet it is also the most difficult to master among the six main forms of the technique.
So, if one were to channel their power into one leg while using the Sun Breathing as with the Thunder Breathing and then release it in a burst to execute a high-speed assault, what would that become?
The answer, Reiger had just demonstrated it.
Tearing through the air was no longer the sound of thunder, but a deafening blast.
The flash was no longer that of lighting, but of fire.
The strike delivered wasnât the "Lightning Flash," but a "Round Dance."
This was an extension technique of Sun Breathing used once by Kamado Tanjirou in the original âDemon Slayerâ seriesâ the "Round Dance Flash."
When Reiger was pondering how to increase his speed while using Sun Breathing, he suddenly remembered this moveâs existence.
Therefore, Reiger tried it out here and succeeded in a single attempt.
"Indeed,"
Reiger silently voiced in his heart.
"After all, Thunder Breathing is a technique I use very often, especially the âLightning Flash,â which Iâve executed as many times as the various forms of Sun Breathing."
"And I have developed a secret technique of Sun Breathing, âBlossom,â just like âLightning Flash,â it is a draw-and-slash."
"With such a foundation, setting others aside, it would certainly not be difficult for me to use the explosive technique of Thunder Breathing while in the state of using Sun Breathing."
Even Kamado Tanjirou managed to do it; naturally, it wasnât impossible for Reiger to accomplish the same thing.
Of course, this was just the beginning.
"Since the trick of the âLightning Flashâ can be used to execute the forms of Sun Breathing, can I perhaps also harness âGod Speedâ to execute the forms of Sun Breathing?"
"If âGod Speedâ is possible, then would âFire Thunder Godâ also be feasible?"
"If I could unleash speed comparable to âFire Thunder Godâ while using Sun Breathing, even when in a strong offensive mode, my speed would not be inferior to that of a speed-focused mode and might even surpass it, right?"
If this concept were to succeed, Reigerâs strong offensive mode would amalgamate the advantages of a speed-focused mode, achieving a perfect state with both comprehensive strength and exceptional speed.
By then, Reigerâs power would surge, and he might not find Lancelot or Gawain as troublesome as before.
"In the original âDemon Slayerâ narrative, Tanjirou even accomplished the unthinkableâcombining Water Breathing with Sun Breathing to use hybrid breathing techniques."
"Therefore, could I not think more boldly and continue to evolve, integrating Thunder Breathing into Sun Breathing, using both Sun Breathing and Thunder Breathing together?"
"What about Wind Breathing? Moon Breathing? Can they be mixed and combined as well?"
As a result of the successful execution of the "Round Dance Flash," Reigerâs mind was flooded with all sorts of ideas.
"Mr. Reiger!"
As Reiger was lost in thought, Matthew cried out in alarm and brought him back to reality.
"Boom, boom, boom, boom, boomâ"
The very next second, a barrage of dark cannon blasts struck, engulfing Reiger while simultaneously unleashing an explosive roar as they hit him.
Facing an opponent who dared to sheathe his sword and stand lost in thought while surrounded and enclosed within their ranks, the Mors no longer hesitated and initiated their attacks.
"Bang!"
The explosive roar, loud enough to create sonic waves, caused the ground to crack and fissure.
However, this time the explosions werenât caused by the Mors, but by a surge of fierce flames igniting.
The flames evaporated the atmosphere, releasing intense heat, and managed to disperse the pitch-black Magic Power laden with an astonishing curse.
The scene resembled a holy fire purging evil as it burst forth in the darkness, quickly and violently flinging the twisting, soft-bodied Mors into the air.
"Sun Breathing·Land Form·Bone-Burning Sun."
Like a fiery vortex, the flaming slash erupted, severing the Mors that were cast into the air.
"Spurt!" "Spurt!" "Spurt!" "Spurt!" "Spurt!"...
The blade of flames, like a sudden burst of firelight, cleaved through one Moers after another before they even had a chance to hit the ground, severing them in two and slaying them on the spot.
The surging flames ignited, enveloping each Moers and purifying, exorcising, and burning them to cinders.
Standing with his sword, Reiger was surrounded by clusters of flames that fell down around him; within them, the Moers gradually burned to ash, creating a spectacle like fireworks in full bloom, sacred and exquisite alike.
"So, so powerful..."
Matthew was once again entranced.
She didnât know what those monsters were or how much of a threat they could pose.
But still, her instincts told her that what she was witnessing was something that couldnât possibly occur on an ordinary day, something beyond the capabilities of ordinary people.
At that moment, Reiger, in Matthewâs eyes, was no different from a god.
He was the god of fire who controlled the flames.
He was the sun god who illuminated the earth.
He was also the War God and Sword God, swinging his blade as if it had a life of its own.
"Mr. Reiger... even more incredible than Sir Gawain..."
Matthew murmured subconsciously, then immediately checked herself in confusion.
"Who is Sir Gawain?"
The girl cocked her head, her face a picture of perplexity, gently diffusing the tension in the air.
"Are you alright?"
Reiger approached and, seeing Matthewâs baffled expression, immediately inquired.
"No, itâs nothing!" Matthew quickly recovered, shaking her head and asking, "What was that just now...?"
"Those were the Moers," Reiger did not press further, simply stating, "Iâll explain the details to you afterward."
"Okay." Matthew nodded soberly but then asked again, "Who is Galahad? And what is an Elf Knight?"
"...You donât know?" Reiger looked at Matthew with a puzzled gaze, saying, "Then why did you use that title?"
"Well... Iâm not sure..." Matthew became hesitant, somewhat uncertain, "It just felt like there was a voice in my head at the time, telling me I could do it."
"That makes sense," Reiger watched Matthew with a wry smile, "Indeed, no one is more suited to use that title than you."
"But, itâs one thing to be Galahad, I didnât expect you to use the title of Elf Knight, too."
"Itâs a good thing youâre a Lesser Servant, though not a true one, but you do possess the traits of a Servant, otherwise, the fairies of this land might die of laughter because of you."
Fairies can distinguish between themselves and humans by scent, Magic Power, and appearance, but they canât discern between a fairy and a Servant.
Therefore, in the eyes of most fairies, Servants are not much different from them.
In other words, both Matthew and Reiger could pass as fairies and would not be seen as humans.
Even if Matthew announced herself as an Elf Knight in front of a crowd, she would likely only elicit expressions of surprise rather than mockery.
Thinking of this, Reiger glanced at Matthew by his side.
The faint glow that once surrounded the girl had now vanished.
But as she came to this place, to Britain, to the land once inhabited by the Knights of the Round Table, the power that was unique to Galahad within her had been fully activated.
Furthermore, with her self-proclamation as an Elf Knight, Matthew now likely received the "bestowed name" blessing familiar to the Elf Knights.
At least, the power that Reiger had just felt, no less formidable than that of an Elf Knight, was definitely not an illusion.
Naturally, that power wasnât the kind of counterfeit goods youâd get from Tristan, but on a level that could compete with Lancelot and Gawain.
"The Knights of the Round Table..."
Reiger murmured nostalgically.
Indeed, it would be quite something to witness those fabled knights on this land.
