Boom—!
A single blow capable of destroying a large galleon or shattering a small mountain, a giant fist of magma.
It collided with Yamato's relatively small spiked club.
The lightning-wreathed club instantly unleashed a powerful force. The shockwave formed by Armament Haki shattered Akainu's Great Eruption with a single blow.
Pieces of magma, large and small, scattered in all directions.
Casually swinging her club to knock away the magma flying towards her and Karl, Yamato looked at the somewhat astonished Akainu and grinned, "Your opponent is me!"
"Thunder Bagua... What is your relationship with Kaido?!"
Akainu, who had just erupted like a volcano, was instantly calmed by Yamato's blow and asked in a deep voice.
"I am Kaido's so... daughter, Yamato!"
Yamato introduced herself, pausing at the gender part, and uttered the two words Karl loved to hear most.
"Kaido's daughter!"
Even Akainu couldn't help but widen his eyes at this moment.
He first looked at Yamato, then at Karl behind her.
Could it be that this kid not only defeated Kaido back then but also stole his daughter?
And Kaido didn't even seek revenge? Was he beaten into submission?
"Hahaha... to think you're Kaido's daughter, how surprising!"
Garp, who was standing by, also gave Karl a thumbs-up and laughed heartily, "Kid, you've really got something!"
"Thank you for the compliment."
Karl looked at Garp with eyes full of fighting spirit and said, "Since the opponents have been assigned, then please give me your guidance... Marine Hero Monkey D. Garp!"
"Let's go. I'm interested in you too!"
Garp retracted his exaggerated smile and grinned at Karl.
In fact, Garp was indeed very curious about Karl.
His birthday was the same as his adopted grandson's, he was two years younger than Ace, and only one year older than his own grandson...
At such an age, to be known as one of the Twin Stars of the East Blue alongside Ace, who had mastered all three types of Haki and the Logia-type Flame-Flame Fruit, he must be an extraordinary existence.
But...
This person had also ascended to the position of an overlord of the seas, becoming one of the highest peaks in the world, relying solely on the three types of Haki and the Logia-type Rumble-Rumble Fruit.
The Rumble-Rumble Fruit, the strongest Logia fruit, shouldn't be that exaggerated.
Clearly, it must be because the other party was a natural-born monster.
However...
As a Marine Hero, Garp had seen his share of natural-born monsters like Charlotte Linlin and Karl.
He had even seen several true monsters and fought with them countless times.
A mere innate monster physique, at this age, shouldn't have such strength.
Otherwise, why would Charlotte Linlin have needed to join the Rocks Pirates in the previous era?
It was precisely because of this that Garp had agreed to Sengoku's forceful request, to see what kind of existence this young man, who was of the same generation as his grandson, truly was.
A few seconds later, Garp understood!
The reason Karl could reach the pinnacle at this age was because he was also... a true monster!
Whoosh—
The moment Garp's voice fell.
Karl's figure, as if teleporting, appeared out of thin air in front of Garp.
It wasn't the electric field teleportation of the Rumble-Rumble Fruit, but high-speed physical movement.
Immediately after, Karl threw a punch that, compared to Garp's iron fists, was as small and cute as a little girl's.
Such a small fist, yet it made Garp feel a powerful presence that he hadn't felt for who knows how many years.
Boom—!
From decades of accumulation and countless battles of experience.
Garp didn't even need to consciously act; his consciousness automatically mobilized the powerful strength within his body and threw an iron fist.
A casual blow, infused with Life Return, seemed ordinary, but was actually a punch with 100% of his normal strength, colliding with Karl's small fist.
In an instant, a violent airflow, like a clash of Haki, erupted from Karl's and Garp's fists.
A portion of the surrounding sea of fire was even extinguished by this gust of wind, not fanning the flames, but burning more intensely.
The two's fists were only deadlocked for about ten seconds.
Then Karl's body, as if gently pushed, suddenly took two steps back.
But, a smile appeared on Karl's face.
Seeing this, a rare look of astonishment appeared on Garp's face.
"As expected of a legendary figure!"
Looking up at Garp, Karl grinned with a face full of fighting spirit.
Being knocked back by Garp was a normal thing.
Because that punch was just an ordinary punch, not even 80% of his strength.
Garp's iron fist, Karl could sense, was infused with Life Return, definitely over 90%, or even 100% of his normal strength.
Here, Karl found another one of his shortcomings.
Besides the special ability of Conqueror's Haki, his Life Return had not yet reached the pinnacle.
At least, there was a considerable gap between him and a master of martial arts like Garp.
But what he lacked in skill, he would make up for with his natural gifts!
And so...
Karl, who had taken two steps back, once again threw an iron fist at Garp.
This punch, Karl also infused with his consciousness, using the technique of Life Return.
"Hahaha... I underestimated you, you monster kid!"
Looking at the fist that was incredibly similar to his own, Garp suddenly burst out laughing.
Then, the way he looked at Karl was no longer like looking at a junior.
With a long-unseen fighting spirit on his face, he seriously responded to Karl's punch.
The sandbag-sized fist once again collided with Karl's.
Boom————!
A louder collision than before erupted with an airflow like a hurricane.
In just an instant, the sea of fire in a radius of several hundred meters was extinguished by this special airflow.
The stalemate this time lasted for a full one or two minutes.
At this time, Yamato had also engaged in a fierce clash with Akainu.
Since they met, Yamato had not just been adventuring.
Karl, treating her as a future first mate and wanting to improve her Conqueror's Haki Infusion, often sparred with Yamato at a full-power level.
From the initial clashes of Conqueror's Haki Infusion, martial arts, Haki, and fruit abilities...
In the past two years, Yamato's strength had also improved considerably.
Except for Benn Beckman, whose strength was not inferior to Shanks', Karl believed that Yamato's strength would not be at a disadvantage, and might even have the upper hand, against the other three first mates of the Emperors.
Therefore, Akainu, without an island-destroying ultimate move, was destined to be unable to defeat Yamato in a short period of time.
