One Piece: The Max-Level Blacksmith of Marineford

"Puff puff!"

Amidst the fierce barrage of bullets, the shields that Batu had previously made for his men began to crumble.

Even the strongest shield cannot withstand an attack of a hundred bullets per second.

Blood mist instantly appeared on the deck.

The Karami, whose shields were shattered, were reduced to pieces of flesh and blood before they could even scream.

Iron Hammer was somewhat bewildered by what he saw; a person who was alive just a second ago had turned into pieces the next.

Even though he had made ample preparations over the past year, he still felt a pang of reluctance when he actually saw it with his own eyes.

The churning in his stomach made him stop firing.

The sound stopped suddenly.

The air was thick with the stench of blood, and the remains of pirates were scattered everywhere.

"vomit!"

The next second, the hammer bent over and vomited.

"Damn it! He killed all my men!"

"Take your life!"

"Shield! Shield break!"

In his fury, Batu conjured up a shield with a bizarre, scribbled appearance.

Batu then stopped holding back and stepped forward with his shield raised.

Seeing this, Iron Hammer quickly wiped his mouth and tried to retreat as fast as he could, but the churning sensation in his stomach made his movements very slow.

"Die!"

"Iron!"

The large shield came crashing down from above, leaving Iron Hammer with no choice but to use his iron block again.

But the next second, he understood what the Iron Block Law meant.

"boom!"

The shield slammed into the hammer, and an explosion rang out instantly.

The hammer was instantly enveloped in a burst of flames.

"puff!"

In the explosion, the hammer was blown high into the air, black smoke billowing from its mouth, and its clothes were torn to shreds.

He had a large bump on his head, but since he had used an iron block, he wasn't injured.

"Hmph, you navy brat, my destruction shield can explode!"

"Take your life!"

Emboldened by his successful attack, Batu became even more ferocious and charged again with his shield raised.

Iron Hammer, spewing black smoke, dared not let him get close.

After shaving several times, they quickly increased the distance between themselves.

But Batu had already become ruthless; no matter where the hammer flashed, he would appear the next second.

"Are you a dog? Why are you biting so tightly!"

"Moonstep!"

Iron Hammer, driven to despair by the relentless pursuit, cursed angrily, his feet shifting rapidly as he took several steps, leaping into the air.

Seeing the hammer disappear into the air, Batu's face was full of resentment.

"Come down if you dare!"

"Come up if you dare!"

"get down!"

"you come up!"

The two instantly transformed into street thugs, neither able to gain the upper hand.

However, Tiechui knew in his heart that he had to get rid of Batu, since he was worth 100 million and perfectly met the assessment requirements.

But his Shield-Shield Fruit is really annoying.

Up close there are thorns, from a distance there are serrated edges, and now there are even explosions.

How did this grandson develop his Devil Fruit ability so well?

Thinking about this, Iron Hammer suddenly realized that he himself was also a Devil Fruit user.

A solution immediately came to mind.

"shave!"

The iron hammer, which was still in mid-air, disappeared instantly and reappeared above Batu.

Batu was overjoyed at the sight and immediately swung the Destruction Shield upwards.

Iron Hammer wasn't going to let him get away with it. He clenched his right fist and threw a punch from top to bottom, but there was clearly some distance between him and Batu. All that could be heard was Iron Hammer's roar:

"Hammer strike! Hit the bull from a distance!"

His right fist slammed heavily into the air, and an invisible wave instantly appeared, hurtling towards Batu with lightning speed.

This really caught Batu off guard.

He thought to himself: You bastard, you don't play by the rules!

The violent shockwave blasted Batu away.

He crashed heavily onto the deck.

"Crack!"

The wooden plank couldn't withstand the violent impact and was smashed open with a large hole.

Batu was forcefully shoved into the cabin.

"Cough cough cough, you bastard!"

This blow caused Batu Gan to vomit blood.

Iron Hammer, on the other hand, was very satisfied with his masterpiece.

This air hammering technique was something he had figured out over the past year, and he didn't expect it to be so effective on his first try.

Not bad.

"Batu, surrender!"

Batu couldn't stand it. He roared and charged onto the deck to fight Iron Hammer again.

"Zigzag Chain Shield!"

A rotating serrated shield hurtled through the air.

"I'll hammer it again!"

The air hammer strike reappeared. Although the serrated shield was incredibly powerful, its material was inferior to other shields. Faced with the hammer's blow, it shattered into pieces and fell to the ground.

Batu went completely mad, and countless shields appeared around him.

"Shields! Thousand Shields Formation!"

"Kid! Die!"

In Batu's rage, countless shields soared into the air and flew straight toward the iron hammer.

"Hmph! I don't care how many shields you have, I'll break them all with my strength!"

"Big Hammer! Eighty! Devastating Strike!"

Iron Hammer's right arm veins bulged as he slammed out a punch.

An invisible wave began to spread in all directions.

Wherever it went, shields and decks shattered.

Iron Hammer, engrossed in the battle, was completely unaware that the value on his panel indicating his Devil Fruit development ability had suddenly increased from 40% to 50%.

Under the full force of the hammer's blow, Batu had no way to resist and was blasted by the shockwave, coughing up blood and collapsing.

Fell into coma.

"Ha ha..."

"Hmph, you little loser, you've already lost!"

Looking at Batu, who had fallen into a coma, Tiechui panted heavily and mocked him.

However, he sounded very happy, not for any other reason than that he had passed his assessment.
