Carefully, little by little, Gray increased his Cell Rotation speed. After a while, though, the friction it produced sent his body temperature soaring, and his skin turned red all over.
"This won't work. My body isn't strong enough to withstand the heat being generated inside me."
"The heat will damage my cells. Damaged cells will shorten my lifespan." That was exactly why Gray hadn't started this process earlier.
Only after he learned Life Return could he use it to absorb nutrients from food and repair his cells. That was what gave him the confidence to begin Cell Rotation.
"Life Return: Repair!" Gray used the nutrients his body hadn't yet absorbed to repair his cells.
About half an hour later, Gray began rotating his cells again, but this time was different.
"Armament Haki Enhancement: Full-Body Hardening!" Using his will to infuse his cells, along with Observation Haki to examine them, Gray could clearly see every one of his cells covered in Armament Haki Hardening.
"This time, I should be able to hold out until I draw out the bioelectric current!"
"Cell Rotation!"
This time, Gray easily raised his cells' rotation speed. His Haki did an excellent job of shielding him from the heat generated by friction.
Little by little, his cells began spinning faster. The current inside his body was drawn out, then joined the rotation.
That small current acted like a spark. Before Gray's cells even reached that speed, friction had already begun to generate electricity.
Bzzzt!
From the outside, electricity danced across Gray's body, like a member of the Mink Tribe generating electricity or Railgun Girl using her ability.
The powerful current began stimulating his cells, but the Haki covering them was also highly effective at defending against it.
"Something's wrong. At this rate, the current won't have any
