One Piece: Start as a mythical beast, practice to become stronger

"So it's you guys who are the experimental subjects..."

Jin An narrowed his eyes slightly, his tone was cold,

"The World Government has lost all its dignity and is using these things as a shield."

However, the Seraphim did not respond at all. They were like cold-blooded killing machines and did not care about Jin An's words at all.

The Seraphim that looked like Mihawk was the first to launch the attack. It flashed and turned into a black shadow and rushed towards Jin An. The blade was as fast as lightning and whistled at him with a violent sword energy.

Jin An snorted coldly and quickly blocked with his long sword.

"clang!"

There was a loud bang and sparks flew.

The moment the blades touched, the impact force almost caused the ground to crack.

However, the power of that Seraph was not inferior to that of a top swordsman!

Jin An felt a slight numbness at the base of his palm, but the feeling disappeared in an instant.

He spun sideways, using the force to shake off the Seraph's blade, then turned the long sword and chopped it back.

However, the next moment, the Seraphim on the other side had raised the energy ball in his hand and bombarded him directly.

As the purple light flashed, Jin An's eyes became stern. He stepped forward and his figure retreated like a stream of light, barely avoiding the frontal impact.

"boom!!!"

But when the energy ball landed, it caused a huge explosion, the ground collapsed, and rubble and dust flew everywhere.

"call out..."

Before Jin'an could stand firm, he heard the sound of breaking air from behind.

He subconsciously turned around and slashed with his sword, only to see the Seraphim who looked like Kaido punching him. The wind from his punch was as violent as a tsunami, sweeping in with a heavy pressure.

"These replicas are really annoying."

Jin An cursed under his breath as his blade collided head-on with Seraphim's fist.

The huge recoil force was transmitted along the blade to his arm, but Jin An took advantage of the momentum to turn over and jump up, and the blade drew a sharp arc again.

The Seraphim joined forces to launch a fierce offensive. Every move was precise and deadly, and the coordination was almost impeccable.

Although Jin An handled the situation with ease, he also realized how difficult these replicas were to deal with - their strength, speed, and even reactions were far beyond those of ordinary strong men, truly achieving what Vegapunk called "human limits."

"Vegapunk...what kind of monster did you create?"

Jin An thought to himself, but the knife in his hand did not stop at all.

He chopped left and blocked right, his figure moving among the siege of the Seraphim. Every ray of light from his long sword carried a domineering aura, and he forced back two Seraphim.

However, he could sense that this was only the beginning.

In the distance, the laughter of the Five Elders could be heard, and Jaygo Lucia Satan Shengyouran said:

"Jin An, how long can you hold on now? These Seraphs are not ordinary pawns. They are terminators prepared for people like you."

Jin An smiled slightly and wiped the blood off the knife.

"Really? Then let me see how powerful these 'Terminators' are."

After saying that, he shook his sword, and the domineering aura on the blade became more and more intense, transforming into a dazzling light, heading straight for the core of the Seraph.

This battle is far from over.

"You really think highly of me."

Jin An raised the corner of his mouth slightly, turned the blade, and his domineering aura overflowed, as if a real wave of air exploded around him.

His eyes swept across the ten people opposite him. Each of them exuded an aura that should not be underestimated. Among them were Seraphim, strong men from the World Government, and even some familiar faces.

It was clear that his former comrades in the navy, whether enemies or friends, were now all standing against him.

The people on the other side did not reply, but their actions revealed murderous intent.

The Seraphim who looked like Mihawk was the first to move. He swept out the miniature black knife in his hand, and the sword energy was like a rainbow, heading straight for Jin An's face.

Immediately afterwards, a purple light gathered again in the palm of the other Seraph, and an energy ball shot towards Jin An's back at lightning speed, trying to block his retreat.

Jin An snorted coldly, stepped on the ground, and rushed towards Mihawk Seraph like an arrow.

"Stab..."

The moment the blades collided, there was a sharp sound of metal clashing and sparks flew.

Jin An only felt a powerful force coming from the knife, but he did not step back. Instead, he used the force to spin and directed the force of the Seraph's knife to the side.

"boom!"

The purple energy ball brushed past Jin'an's shoulder and hit the ground. The shock wave of the explosion created a huge pit in the ground, and gravel flew like rain.

But Jin An was not disturbed. His blade turned into an afterimage and slashed straight towards Mihawk Seraph's neck.

However, the Seraphim next to him suddenly appeared behind Mihawk Seraphim as if by teleportation, and deflected Jin An's attack with a palm.

At the same time, the Seraphim who looked like Kaido suddenly jumped up, and his fist smashed down with pressure like a mountain and sea, aiming directly at Jin An's head.

Jin An's eyes focused, he stomped his feet on the ground, and his whole body spun like a whirlwind, and the knife in his hand drew a huge arc.

With a loud "boom", the domineering aura surged and the sword energy was like thunder, which directly dissolved the fist of Jinbei Seraph and at the same time forced back several approaching enemies.

"Ten people?"

Jin An sneered, his voice full of disdain and fighting spirit.

"It's no use having more people. Come on all of you. I want to see who will be the last one in this game!"

The Seraphim did not show any emotion; they coordinated their attacks mechanically, with movements so precise that there were no flaws.

Almost at the same time, Mihawk's Seraph's blade, Crocodile-type Seraph's energy palm, and the joint offensive of several powerful World Government figures swept towards Jin'an like a storm.

Every strike blocked Jinan's escape space.

Jin An was still at ease, his figure looming among the flashes of swords and explosions, the long sword in his hand was like a living thing, blocking, stabbing, or slashing, each move was full of power and exquisite angles.

"Crack!"

With a crisp sound, Jin'an's blade accurately cut off a sharp spear approaching him, and then he slightly tilted his body to avoid an energy wave from a Crocodile-type Seraph, and swept the long sword out, forcing the three strong men of the World Government to retreat again and again.

“No matter how many ants there are, it cannot change the fact that you are ants.”

Jin An stood up straight, holding his sword horizontally, his eyes as sharp as a torch.

"Come on, I'll play with you till the end."

As soon as he finished speaking, the ground beneath his feet cracked again. The Seraphim and the strong men seemed to have sensed the danger in Jin'an. They no longer held back and launched a more intense offensive.

The siege of ten people became more and more impenetrable. The sword energy, fist wind, and energy explosion intertwined into a chaotic killing vortex, enveloping Jin'an's figure.

The battlefield fell into a stalemate again, but the powerful aura belonging to Jin'an was like an unquenchable flame, still burning in the center of the battlefield, making everyone dare not approach easily.
