After a prolonged battle, the void is filled with thin and long cracks of varying sizes. Once void cracks appear, they require a long time to gradually heal.

The humanoid being retreated violently, its life aura suddenly dropping by more than half. Its form made of golden smoke began to tremble, showing signs of instability.
