The Black Dragon, previously lying peacefully in the courtyard, suddenly felt a powerful force engulf it.
A mysterious beam of light struck its body with unerring accuracy.
In an instant, the Black Dragon's body began to tremble violently, as if endless energy were being injected into it.
Its muscles expanded rapidly, and its bones cracked. Its entire body was growing at an astonishing speed.
As its size increased, the Black Dragon's appearance also underwent a drastic transformation.
Its once gentle face had morphed into a ferocious and terrifying visage. Sharp fangs protruded from the corners of its mouth, radiating a chilling aura.
A pair of piercing dragon eyes flickered with a cold light, revealing traces of murderous intent.
Its sharp claws became even more lethal, seemingly capable of tearing through steel with ease.
