Only when your fist is broken into pieces can you survive.
On the first day Long Sheng traveled to the pirate world, he was bitten out of his bones by a hungry wolf.
It was also that day that he awakened - [Tenacity].
Repair, heal, regenerate. Every near-death is a reshaping; every scar is a medal.
He smashes mountains with his fists, resists knives with his bones, and shakes the laws of this world with his flesh and blood.
There is no devil fruit, no innate power, just a soul that never heals, and a pair of fists that become harder and harder as they are broken.
"What are your abilities?"
"Be beaten."
"... And then what?"
"Then it was my turn."
When the galactic impact tears the sky apart, the world finally knows that some monsters are born. Some monsters fight themselves out.
This is not cheating, this is the art of being beaten.
