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

“Ice Age!” Kuzan placed both palms close to the sea.

The sea surface was rapidly frozen, and the warship was also frozen at a very dangerous angle.

The pirates were not so lucky; their eyes filled with terror as they couldn't even beg for mercy, instantly turning into ice sculptures.

“We're saved.”

The marines released their hands and landed steadily on the ice surface.

“Don't let your guard down!” Kuzan warned. “The guy who attacked us is definitely still under the sea.”

“I feel like the danger posed by this guy in the sea is even greater than the sea monster we encountered yesterday...”

The marines were still shaken, looking at the dozens of meters high ice pillars beside them.

“This place is too close to the Calm Belt; encountering danger twice in such a short time.”

“I think we can leave this sea area...”

“Let's wait for Captain Jin'an's notification...”

The encounters of the past two days had left them shaken, but they made a living doing this, and being with danger was a common occurrence.

“Boom!!!”

A violent tremor came from the ice surface, startling the marines who were chatting, thinking the monster in the sea had returned.

“Everyone, get on the ship.”

A familiar voice came, and the marines looked at each other, looking towards where the warship was.

The thick ice layer below the warship became fragmented, and the warship returned to its original state from its precarious position.

Even in the direction of advancement, the ice layer just revealed a straight route.

“Yay! Long live Captain Jin'an!”

The marines cheered and formed an orderly queue, climbing up the ladder lowered from the warship.

Below the frozen sea surface, the giant beast hidden in the dark depths of the sea finally found the culprit who had deceived it.

“Roar!!!”

A roar rang out, and it suddenly broke free from the ice on the sea surface, ice blocks and water splashing everywhere.

“Boom!!!”

With a deafening roar, the giant beast leaped out of the water, a figure over a hundred meters tall soaring into the air, dazzling lights dispelling the darkness on the sea in front of its fish head.

It was actually a lantern fish giant that exceeded imagination!

This lantern fish giant was majestic and imposing, its scales shimmering with a deep reddish-brown light, as if it were a mysterious creature from ancient times.

“What kind of lantern fish is that?”

“The warship isn't even as big as one of its teeth!”

The marines on the sea stared in astonishment at this scene, and they couldn't help but be shocked by the appearance of this behemoth.

Moreover, the imposing aura of this giant lantern fish was unbelievable, as if it were the true master of the ocean.

“Kuzan, freeze the waves!” Jin'an said in a deep voice.

When the lantern fish fell from the air, it stirred up a sea wave, and this momentum was several times more terrifying than a tsunami.

Unfortunately, before Kuzan could deal with the giant wave covering the warship, the lantern fish in the sea let out another roar.

“It's too late!” Kuzan looked anxious.

In this vast sea, if the warship was destroyed, even if they survived the lantern fish's attack, they would hardly escape death.

Under the majesty of the lantern fish giant, the ocean seemed to be silent, leaving only the giant beast's roar echoing in the night sky, it was the undisputed overlord of the sea, in charge of the lives of all living beings in this sea area.

......

[Ding! System side quest issued!]

[Fight with Lord Lantern and ensure the safety of the marines.]

[Quest reward: Training space time, a random Devil Fruit, 500,000,000 Berries, Store Points +10000.]

[Please host be careful, this opponent's strength is beyond your imagination!!]

Jin'an finally knew what the information given by the system meant.

The culprit who swallowed the island was this lantern fish in the sea!

Closing the system panel, Jin'an smiled wryly, the monster in front of him was one of the top monsters in terms of size that had appeared in the pirate world so far.

Such monsters may have skin that is tens of meters thick, and Jin'an didn't know if his current strength could shake this behemoth.

“Kuzan, the safety of the marines next is up to you.” Jin'an tore off the coat he was wearing. “Dof, you must also concentrate on training during the days I'm away; I'll come and check later.”

“What are you...” Kuzan hesitated.

“Don't be stubborn!” Doflamingo was also anxious. “I'm still waiting for you to teach me some powerful moves!”

“You have my life card.” Jin'an showed a confident smile. “I won't fail!”

Kuzan understood what he meant; the life card could tell if Jin'an was safe, and he was preparing to fight the huge lantern fish to exchange for a chance of survival for them.

“Roar!!”

With the roar of the lantern fish giant, the ocean seemed to be stirred up by huge waves, the wind howling and the waves surging.

And at this moment, Jin'an's body slowly rose into the air in the astonished eyes of everyone.

Floating in the air, Jin'an felt a strange power surging within his body, carrying him up into the sky.

In the eyes of everyone, Jin'an's body continued to grow larger, and his body gradually merged with the clouds, he felt a powerful energy surging within him.

His eyes flickered with a strange light, and he seemed to be undergoing a long-awaited transformation.

At the same time, the lantern fish giant rushed out of the sea, its body towering, like a huge mountain, its eyes flashing with fierce light, and its mouth making a deafening roar, as if venting its inner dissatisfaction.

Then, the lantern fish giant waved its tail, and a huge whirlpool suddenly formed on the sea surface, devouring everything in the ocean, and the warship was also caught in it.

The warship kept spinning in the vortex, being ruthlessly devoured, and the marines controlled the warship trying to escape, but they seemed powerless and insignificant in the face of the huge power.

“Don't panic, grab everything around you!”

As the clouds churned, Jin'an's voice came from the sky.

Suddenly, the clouds were torn apart by a huge claw, and a huge beast emerged from the clouds, its body extremely huge, its skin bright cyan, as if it were from a distant mythical legend.

This beast carried an incomparably powerful aura, as if it were the embodiment of heaven and earth, its eyes as bright as shooting stars, projecting an unparalleled majesty and power, its huge body standing in the air, blocking the moonlight, casting a silent shadow, like a sea god.

Jin'an transformed into a Azure Dragon, overlooking everything, his body standing straight in the sky, his dragon eyes flashing with cyan light.

The dragon's body exuded a powerful aura, his dragon tail swayed, stirring up storms and huge waves, his dragon claws clenched the void, as if controlling everything.

“Azure Dragon Fruit?” Kuzan murmured, looking up at the sky. “It's the first time I've seen Captain Jin'an use his fruit ability; I didn't expect it to be this situation...”

The expressions of the marines changed from astonishment to surprise, and they watched as their warship escaped the shackles of the vortex.

“We're flying!”

The warship was shrouded in flame clouds.

Under the protection of the flame clouds, they soared into the air and flew into the sky.
