one piece: gene extraction and fusion system

"Extract abilities."

After praising the creature, Mio silently uttered the command in his heart.

The abilities began to extract immediately.

Mio looked forward to the result.

The creatures cultivated this time were all impressive. No matter what ability he extracted, it would increase his combat power—well, except for [Fearless].

"Starting extraction~ Extraction successful. Congratulations on extracting the ability [Endless Life] and one-tenth of the all-round attributes of the creatures you cultivated this time!"

Seeing the prompt appear before him, Mio's eyes lit up with surprise. "That's a good ability."

In this world, any ability used in battle—whether it be Haki, swordsmanship, physical techniques, or Devil Fruit powers—consumed stamina. One could say stamina was the core foundation of a strong fighter.

Mio's physical endurance wasn't weak, but compared to the true powerhouses of the sea, he still had room to grow.

Now, with the ability [Endless Life], that weakness was immediately addressed.

After all, [Endless Life] rapidly restored stamina.
