Pirates: Trainer on the Straw Hat Ship.

"Luffy! Be careful!"

"This is my final blow!"

"Sun God Shiranui!!!"

bake! ! ! !

A bright red flash suddenly appeared on the sparkling sea, melting the golden sunlight and making the sea red.

The blazing flames formed a vortex in the air and soared into the sky, and soon condensed into a huge flame giant. The terrifying high-temperature flames turned into fists and suddenly blasted forward!

On the other side, Luffy, who had entered gear 4, used the air pressure from his legs to float in the air, with a smile on his face.

After fighting with Ace for half an hour, the energy and blood all over his body was surging crazily.

Facing the attack from Ace, Luffy took a deep breath.

The air flow seemed to materialize, hanging on both sides of his mouth.

The next moment, Luffy's eyes suddenly flashed: "Sorry, Ace!"

"The person I am today is completely different from yesterday!!!"

"And this is also my final blow!!!"

As soon as he finished speaking, Luffy's two thick, mechanical-like arms suddenly pushed back, compressing his fists into his arms, like a heavy cannon ready to go.

The clicking mechanical sound sounded, more like announcing to the opponent in front what kind of terrifying power the crimson arm contained!

"Rubber...double-bomb rocket launcher!!!"

boom! ! ! !

Two giant black and red fists like cannonballs suddenly attacked!

With the power of Armament Haki, Luffy's fist directly broke through the flame giant's body, and he found Ace's figure along the scorching flames.

"What!? How did this kid suddenly become so strong!?"

Ace, who had never experienced using the Pokémon game world to upgrade and become stronger, immediately had a look of surprise on his face.

But before his brain could react, Luffy's fist had already struck his body.

At this time, Luffy's physical foundation may be slightly worse than when he just finished training from Rayleigh two years later...

But due to the increase in Pokémon energy and the effects of bodybuilding moves, his current strength has surpassed what he was when he defeated Doflamingo in the original timeline! ! !

Whoosh! ! !

A ray of fire suddenly flew out of the flame giant's body like a falling meteor and hit the forest in the distance!

With a rumble and a mournful cry from the earth, countless birds flew away from the lush dense forest and fled into the distance.

The originally mighty flame giant also turned into little stars and dissipated in the air.

"Hey!"

Luffy, who knocked Ace away for the first time, suddenly had an excited smile on his face.

Looking at the burn damage that had begun to spread down his arm, Luffy suddenly had a pink shimmer and a light breeze around his body, using the ability of Bright Storm to eliminate the burning state left by Ace. .

Just the next second, his huge body suddenly shrank as if it was leaking air.

"Sure enough, the domineering power is still a bit insufficient..."

Unable to maintain his fourth gear, Luffy returned to his original body and landed on the soft sand, panting.

On the other side, with the one-handed move of Chihong who was watching the battle from a distance, Ace, who was supposed to fall into the hole in the forest debris, fell directly from the extra-dimensional hole back to the beach.

Compared to Luffy, whose physical strength has been greatly reduced, Ace's condition is obviously much better and he is still capable of fighting.

However, under Luffy's blow, he was also seriously injured, and a trace of blood spilled from the corner of his mouth.

His body was covered in scars and in an unspeakable state of embarrassment.

wow——

A piece of green grass spread from the soles of the red feet, all the way to the bodies of Luffy and Ace.

Seeing this scene, the two people who had already become proficient suddenly threw their heads up and fell down, lying on the grass field to recover from their injuries.

At this time, Chi Hong walked on the green grass and came between Luffy and Ace, his eyes swept over the two embarrassed figures.

Then he suddenly clicked his tongue: "The problem is still very serious~"

Red first looked at Ace: "First of all, you, Ace."

"Although you did listen to me and no longer rely too much on the fruit's ability to fight..."

"But now you are just using your energy and energy that was originally used on the fruit ability instead on the fire Pokémon's moves."

"Although jetting flames can indeed make your flame temperature higher, it also has a certain burning ability."

"But the fundamental problem you have now is that your physical and mental resistance is too weak!"

"Logically speaking, with your strength, you shouldn't be knocked away by Luffy so easily!"

"This is a problem with your subconscious mind. Your two-color Haki and even your Overlord-color Haki cannot give you an advantage in battle!"

"You have to adjust yourself!"

"Otherwise, no matter how talented you are, it will be difficult to join the ranks of the top experts!"

Red scolded Ace without mercy.

Although judging from the result of the battle, Luffy, who was unable to use Haki, would definitely not be able to defeat Ace, who still had some physical strength left.

But this was what was supposed to happen, and it couldn't be a reason for Ace to shirk.

"I...I will adjust..."

Ace, who was lying on the ground, didn't offer any rebuttal.

In fact, he had heard Chi Hong say the same thing more than once, but the convenience and power of Devil Fruit abilities had already created inertia in his body, and it was not easy to change.

There is also the issue of domineering that Chi Hong mentioned...

Perhaps it was because he had stayed with Whitebeard for too long, and the family-like warmth brought by his companions had stopped him from pursuing too much power.

So until now, his level of Overlord Haki is not much different from that of Luffy who had just awakened.

There is no problem in cleaning up the trash fish, but it is a bit difficult to use it in battle.

"I hope so."

Chihong, who could see that Ace was indeed making corrections, did not say anything more, but directly turned his gaze in Luffy's direction again.

of course.

Under the training of Red Red who has traveled through time for almost three years now, Luffy has long known what path he wants to take.

All the problems he is showing in the battle can be attributed to his own lack of domineering power and lack of proficiency in using the fourth gear, which can be compensated for.

This problem is not difficult to solve.

When it comes to cooking, just practice more!

Whether it's sparring in real life or fighting in the game world, as long as Luffy keeps trying Gear Four...

With his potential, it won't take long for him to completely master the fourth gear.

As for the next 5 gears, we can only leave it to fate.

After all, even Chi Hong has no idea how to get Luffy to develop Gear 5.
