Letting the two girls be, Caelum took the moment to apply what he had learned to his Myriad Blade Technique. He stood silently concentrating on the mental images of a weapon grasped by his hand.
His inability to physically manifest his mental energy only applies to spiritual creatures such as ghosts and spirits.
Caelum had yet to find someone worthy of clashing weapons with and took a while to decide an opponent to fight.
There is one person who stands above all sword users that even on earth made him fascinated. A man who mastered two sword styles and had been recognized as the strongest swordsman.
His frame is slightly hunchback wielding two uneven blades with one smaller than the other. He exudes a ferocious beast that had sliced countless humans unchanged by slaughter in war and his fierce gaze sharper than his own blade capable of cutting you down without a second thought.
Caelum had his Martial Art combined with his own Myriad Blade Style yet comparing it to the original is nothing but mere imitation.
It lacked what made the technique to be feared yet Caelum only imagined everything that he knew about the person. He had not met him in his previous life and didn't interact with humans when he was the God of Mount Tempest.
He spent it mostly with his family and training, never bothering himself to the outside.
Regardless, Caelum could feel the silhouette before him radiating a more dense air than Doppo. The weight of his body, the texture of his skin and the grips that held the two blades.
Meanwhile, Hana who was watching to the side while her friend slept in her lap was curious at what Caelum was doing and took a video.
She is not a fighter and unable to see the manifestation happening before Caelum only saw him appear frightened and shaken then shocked to see him fall into the ground without one touching him.
He appeared to be in horrendous pain squirming in pain before flipping his body laying on his back, out of breath.
'Amazing! I only use my knowledge about the man yet able to slice me into pieces in the blink of an eye!!'
Earlier, before Caelum could react his body was sliced into multiple sections precisely sliced through every part of his body.
He was cut akin to a hot knife cutting through butter. Everything was only in his mind and far from the true Miyamoto Musashi yet the power already far surpasses Doppo.
This kind of ability can only be found when that person lives through a life and death battle with no rest while perfecting their martial art to the peak.
A Level of a Great Grandmaster that transcended the limit of a human and was able to cut without a blade. It had made them very limp, the blade itself making it into part of their body.
This is the same to Unarmed Martial art like Doppo Karate that after devoting his life in practicing this art had become part of his own existence.
It was no intent nor the mystical power only the power of a human surpassing themselves. A body of mortals that broke through by acquiring the essence of their martial art.
"Are you alright? What happened, a moment ago you were standing then the next you're laying on the ground?"
"It's part of my training. Have you heard of Shadow Boxing?"
He asked the young girl while standing up, dusting off the sand caught by his body.
"Yeah, I heard about it where Boxers use their Imagination to fight someone. Is this what you did?"
"Yes, you might not have seen my opponent since you're not a fighter."
"Wow, then why did you instantly fall rather than fight your imaginary opponent?"
"It's because my opponent was too strong."
Caelum gave slightly chuckled wounds, his pride being defeated by a phantom of Miyamoto Musashi. He pondered if it was the real deal would he still be alive now?
Probably but he would lose a limb or two from encountering this monster. Though, it would be an honor being cut by the famous swordsman.
"Who were you fighting with?"
"Miyamoto Musashi."
"What!? The famous Miyamoto Musashi!? The greatest swordsman who ever lived?"
"At least you know you're history. Yes, that person but he is on another level."
He compares Baki, the only pseudo Great Grandmaster level that he had seen so far, with the legendary swordsman. The answer is a mystery as Caelum had yet seen Baki's full power along with Miyamoto Musashi.
However, he personally thinks that the latter would reign victorious based on the phantom's strength alone.
"Can you show me some moves?"
"Sure."
Caelum took a stance, deciding to change his opponent back to Doppo as Miyamoto was out of his reach. He was far too strong for his immature Martial Art.
He had grasped quite a bit of Doppo allowing to fight a portion of the power from the real Doppo. His blood circulates through his body, flexing his muscles and breathing in a rhythmic pattern.
The style was the gentle fist from the Naruto verse that perfectly synchronized with his Painting scripture as the movement akin to the stroke of a brush.
Hana took a video in awe seeing his hands moving slowly and smoothly like pieces of ribbon dancing with the wind. After his palm pointed up and down did he execute precise movement of the gentle fist.
The Gentle fist focuses on internal damage that is perfect when the opponent has a thick hide of muscle pointing in their weak points blocking the flow of blood.
In contrast, the Strong fist style focuses on dominating their opponent with their immense strength and durability.
Caelum preferred the Gentle Fist over the Strong fist despite being a power hungry beast when fighting in the past. Though, he had already combined the two styles into one.
He uses this gentle fist to fight phantom Doppo due to focusing more on precision than confrontation.
The young girl watched agape unable to process the movement due its tremendous speed that could hear the flick of the wind.
She saw him move in a precise manner using the two fingers to poke the air that made her recall a show she once watched.
'My eyes now have been opened!? How can a human move like that?'
Her bewilderment did not stop their noticing Caelum was bleeding and had few bruises. She wondered if there's an invisible person fighting him.
Meanwhile, Caelum movement grew sharper and precise while his muscle tearing then tightened, tempering his body to utmost limits causing his body to steam.
He decided to end it by getting up close enough redirecting his strike before grabbing and pulling it's body then kneeing his chin.
The phantom gradually faded away while Caelum wiped the blood from his mount feeling refreshed upon growing stronger. He looked down seeing his footwork then frowned as it was far too chaotic from what he desired it to be.
'Its too rough and I produce far too much dust. The best thing I should do is begin from the basics and read some books. I have knowledge about history but it's best since this world may be different from where I lived.'
Caelum knew that in each world there may be many minor to major differences like he did not have an anime called Tensei Shitara Slimes. He only knew after linking himself to another timeline by his Omniscience.
Having decided on what to do change his attention to Hana who was confused and shocked.
"Why are you bleeding!? Wait, come here, let me help your bruises."
"Hahaha I do like the gesture but I'll be fine. My body is more sturdy than normal people."
He reassured her while giving a bright smile then went closer as the sleeping younger eyes began to twitch and finally open.
"...where am I? What happened?"
"Oh, Miko, you're finally awake! I'm so glad!"
Her friend tightly hugged Miko who slowly stood up while turning her attention to Caelum still felt drawn to him by his mesmerizing light.
Then she noticed her mind felt more calm and clear then realized it was the first time she slept without having a nightmare and looked at him who gave a light nod seeing her on the verge of tears but held it in.
