Rex kept the barbarian's head plunged into the pool of lava until his head melted away.
No use in torturing the barbarian when his mind was already made up.
Doing so would be a monumental waste of time—which Rex didn't need right now. Once the body was limp, a powerful discharge of fiery energy blasted the surroundings, but Rex already saw this happening through his Law of Foresight.
His senses picked up a rising heat inside the corpse, so he used the Law of Foresight.
And from the lens of that power, he saw the discharge riling the entire volcanic mountain and causing a big lava explosion. Rex would be completely fine, but the soldier from the Red Skull Elite Force behind him wouldn't.
So, he prevented that from happening.
Kingly energy burst from his forehead and tunneled the fiery discharge, sending it straight to the sky.
It was given no chance to rile anything.
Rex dragged the corpse back to the center and dropped it.
