one piece: gene extraction and fusion system

"Sir, you should let me go now, right?" Lucifer asked Mio hesitantly and nervously. Seeing Hei Yan's transformation, Lucifer felt that his purpose had been fulfilled and that he could finally leave.

Hearing this, Mio grinned. "You're right. You can leave now."

Lucifer's face immediately lit up with joy.

But the next moment—

Swish!

A cold gleam flashed as the Raikiri on Mio's waist was drawn in an instant. A single slash later, Lucifer's head was cleanly separated from his neck, landing with a dull thud on the ground before rolling to a stop at Mio's feet.

"Congratulations on collecting the pirate (sensory) gene!"

A system prompt appeared on the panel in front of Mio.

Not far away, a massive Susanoo erupted into view and delivered a powerful punch, collapsing an entire row of houses and killing many pirates in an instant.

At that moment, Hei Yan felt a familiar presence within the range of his Observation Haki. His eyes widened in disbelief as he turned toward the source. "My Lord?!"

Seeing Mio's unmistakable silhouette, Hei Yan rubbed his eyes, almost unwilling to believe what he was seeing.
