Everyone saw how ferociously that bloodied old dragon behaved under the sun.
Countless sea monsters in the area gathered around and surrounded the old dragon.
Roar!
The old dragon roared again. Everyone saw the scales all over its body beginning to break piece by piece; this was an effect of the world's shackles.
Everyone seemed to be able to see a huge hand in the world around it pressing down on that old dragon, preventing it from moving about.
The scales all over that dragon's body were resisting the terrifying pressure surrounding it.
That terrifying aura around the old dragon that sent shivers down the spines of many began to gradually dissipate before long. The scales all over its body no longer broke, and the beast was no longer covered in blood.
It seemed as if the beast had finally gotten used to the limitations placed on it by the world's shackles.
