The shackles around the Devil kept breaking apart, one after another. As more and more chains broke, he was able to use even more strength to break the chains even faster.
The chains that were made by a being that was considered to be the strongest broke like they were made of a thin layer of glass, unable to resist the onslaught of the brutal force resisting them.
After an unknown amount of time, the chains were finally broken completely, freeing the Devil from its grasp.
Even as the Devil was freed from the shackles, his strength didn't stop increasing at all. The entire space around him was breaking apart slowly.
Even the Abyssal Beasts at the core of the Abyss sensed that strength yet terrifying energy which made them tremble to their core.
