Shock, incomprehension, and disbelief appeared on Kaido's face.
He was shocked that a minor member of the Roger Pirates could possess such strength.
He could not understand how sword slashes could be used like this.
He could not believe that a brat had left him with so many wounds.
After his expression changed drastically, he flew into a rage, ignoring the sword energy attacks entirely as he charged straight at Zesi.
"Azure Dragon's Roar: Shock a Hundred Li!" Zesi gripped his sword with both hands.
The blade, imbued with powerful Armament Haki, trembled and vibrated at tremendous speed.
An earth-shaking dragon's roar rang out from the blade.
Behind Zesi, the manifestation of an azure dragon a thousand zhang long flickered in and out of sight, radiating a terrifying draconic presence.
The space around the sword distorted from the millions of vibrations passing through its blade every second!
"Hah!" Zesi gave a sharp cry and swung his sword.
This strike released no slash of sword light.
But as the sword descended, an invisible force crushed everything within a hundred li beneath it.
Yet although this invisible force could pulverize everything within a hundred li, it could not hurt Kaido.
Kaido's spiked club tore an opening through the invisible force and continued toward Zesi.
But in truth, the blade, blurred by its extreme vibrations, was this move's real killing strike.
In the blink of an eye, Zesi's sword and Kaido's spiked club collided again.
The greatest sound was silence.
The two terrifying forces collided, and tremendous power burst from their weapons, plowing through their already devastated surroundings once more and turning shattered rocks into sand and dirt.
That terrifying force also traveled into Zesi's and Kaido's bodies.
Both men were sent flying backward at the same time.
Zesi flew back over a hundred meters before finally stopping, a testament to the power of that force.
After landing, blood trickled from the corner of Zesi's mouth.
"Bastard!" Zesi was furious too.
This was truly an undeserved calamity.
He had only wanted to enjoy a good meal. Was that really so hard?
Other people had a lovely Lady Lin fall into their laps from the sky.
He, on the other hand, had Kaido fall out of the sky.
The man had started fighting without even letting him get a word out.
The more Zesi thought about it, the angrier he became.
He abruptly seized his sword and charged at Kaido again.
Kaido had also been injured in their last clash.
The more Kaido thought about it, the angrier he became too.
Being injured by those strange sword moves could still be chalked up to his opponent's tricks.
But when he unleashed his strongest attack and met his opponent head-on, he had actually been injured.
To think that someone barely into his twenties had left him in such a sorry state-how could Kaido not be furious?
The enraged Kaido ignored his injuries entirely and charged at Zesi again.
The two immediately clashed once more.
This battle lasted an entire day and night!
Back when he watched anime, he had seen fights that lasted for days and nights.
He had thought those were all exaggerations.
But only after coming to this world had Zesi learned.
There really were battles that lasted for days and nights.
Take his battle with Kaido, for instance. The man was simply a monster.
Zesi's sword could cut through his skin and flesh, leaving wounds on his body.
But it could not cut all the way through his flesh.
His muscles formed layer upon layer of shields, blocking both the sword and its sword energy.
With Armament Haki added on top, even Zesi using the Tremor-Tremor Fruit could not inflict overly serious injuries on him.
Most importantly, he also possessed an incredibly terrifying ability to recover.
Even if he was badly wounded, he could recover very quickly.
The same was true of Zesi. Although his recovery was far inferior to Kaido's, his defense was not lacking at all.
Through years of constant training with the Tremor-Tremor Fruit, Zesi had thoroughly tempered his body, skin, muscles, and bones.
With Armament Haki added in, Zesi's defensive ability was not much worse than Kaido's.
Besides Armament Haki and his physical defenses, he also had the Tremor-Tremor Fruit's defenses.
Zesi's Tremor-Tremor Fruit kept his own body vibrating intensely at all times.
While these vibrations trained Zesi's body, they also protected him.
These vibrations were like Zesi's muscles. Any attack entering his body first had to get past them.
That was why breaking Zesi's skin was easy, but driving an attack into his body was exceedingly difficult.
Harming Zesi's internal organs was even more out of the question.
All of this was actually unnecessary to mention. Even for an ordinary powerhouse, breaking Zesi's skin and getting through his Armament Haki was already exceedingly difficult, let alone anything else.
It was their two freakishly powerful constitutions that allowed them to fight for so long.
In the end, Zesi proved one move better, severely wounding Kaido with his supremely powerful Azure Dragon's Roar: Sword Draw and forcing him to transform into a flood dragon and flee.
"Everyone says Kaido isn't afraid of death, that he goes around courting death and trying to kill himself. Looks to me like he's afraid of dying too!" After Kaido fled, Zesi sat on the ground, panting and disheveled, and laughed.
In truth, if Kaido had not fled, he would have.
Azure Dragon's Roar: Sword Draw was the most powerful of all Zesi's sword moves.
This strike was somewhat like a sword-drawing technique.
The sword gathered momentum within its sheath before being drawn, unleashing incomparably terrifying power.
It was a move that brought together the culmination of Zesi's swordsmanship, Haki, and Devil Fruit.
But its consumption was enormous too.
He had already fought desperately against Kaido, and now he had used the hugely draining Azure Dragon's Roar: Sword-Draw Slash.
Zesi had already exhausted most of his stamina.
If the fighting continued, his situation really would not be good.
"As I thought, this kind of long saber still doesn't suit me. Looks like I'll have to find someone to forge me a sword sometime!" Zesi said.
The blade in Zesi's hand was quite good. It was a trophy he had acquired over the past few years and belonged to the Skillful Grade Sword class.
Although it was only a Skillful Grade Sword, his constant tempering with Armament Haki over the years had gradually put it on the path toward becoming a Black Blade.
Unfortunately, Zesi's swordsmanship differed from the swordsmanship of this world-or rather, its saber techniques.
His sword moves were more fluid and versatile. A double-edged Chinese straight sword would suit him better.
