Seconds become minutes as waves of the world's energy flooded into the Refinement Cauldron, coalescing into Old River's body and revolving around it, improving every cell.
Red Hawk, Blue Crow, Specter, and Ghoul watched solemnly at the cauldron since they knew they would be next. Even if Old River were to perish, that would not deter the man with the red mask from experimenting with them.
"¡Boom!"
A small blast echoed from inside the Refinement Cauldron after nearly an hour. Just as the four Atroxs imagined Old River's body had blasted to pieces like a balloon full of blood, the lid opened, and a figure emerged from it.
Shock and surprise appeared on the faces of the Atroxs when they saw that Old River was not only fine but also seemed much younger now, no different than a middle-aged man.
