one piece: gene extraction and fusion system

"Should we wait here, sir?" Lilith asked, gazing at the calm sea before her. Mio had just explained the nature of the Radluff Permanent Pointer, and she understood now that the island tied to the pointer lay deep underwater, encased in a membrane.

This island would only surface when a rising current occurred.

But if they were to wait for that current, no one knew how long it would take.

Mio shook his head. "No need. I'll dive down."

"You all stay up here," he added, glancing at the group. Some of them were Devil Fruit users who couldn't enter the water, and in truth, only one person was needed for the task.

Without another word, Mio leapt straight into the sea.

Underwater, his body darted forward like a shadow, swapping places with various lifeless objects on the seabed using his ability.

It didn't take long.

Soon, Mio spotted an island wrapped in a protective bubble membrane.

He held his breath and swam to the island's exterior, passing through the bubble and entering its enclosed space. Gravity took over, and he began falling—until he halted mid-air, adjusted his stance, and landed lightly.

Ahead, perched on a cliff, he spotted the wreckage of a ship. Around it lay piles of gold and silver treasure, glinting dimly in the filtered light.
