A long trail of black flame flashed across the void, as if carving a pitch-dark wound into the nothingness.
Seeing this, the Demonic Beast's eyes sparkled with excitement. As it continued its mad dash forward, it opened its mouth and spat out beams of red and black light.
The black firebird let out a clear cry and, just as the light beam was about to hit it, it exploded into specks of black flames with a "bang".
The next moment, behind the strange Demonic Beast, clusters of black flame appeared, which then converged into one spot and transformed back into the black firebird.
No sooner had the firebird reappeared than it extended its sharp, black-light-gleaming talons like knives, ripping through the air with a piercing gale, and aimed for the weak spot on the beast's back.
Feeling the wind from behind, the Demonic Beast sharply turned its head and opened its mouth wide, spewing out more than a dozen fist-sized balls of black and red light, flying towards the firebird.
