"Inner destruction fist."
The old demon glanced at Iwan while saying the name of the 'first fist' before looking at Barbero.
"My disciple, Barbero, look at this carefully."
The old demon said to Barbero before pulling back his right fist.
But, this also allowed Iwan to look at the steps of the first fist that had left half of his body in a thrashed state.
The old demon threw a straight fist. To Iwan and Barbero, it looked like a simple punch that kids would throw at one another in the alleyways.
But, everything changed when the old demon added the twist of his shoulder to the power of his fist that had already reached the maximum range.
Iwan could feel the space around the fist distorting. But, it wasn't only him as Barbero was seeing the same thing.
