At that voice, the entire battlefield seemed to fall silent. Though the fighting continued, humans and Ferocious Beasts alike began holding back, all turning their attention toward the source of the voice.
Those who were only in the Spirit King Realm, whether human or Ferocious Beast, paid it no mind. A master capable of unleashing such terrifying pressure would never concern himself with them. They were better off continuing their fight here.
The violent aura suddenly withdrew, and a massive winged, two-headed lizard-like creature appeared in the sky. Its appearance resembled that of a winged True Dragon, though its body was more slender and natural. Its blue-green scales shimmered with captivating radiance beneath the sun, while its long, narrow tail swayed through the air, stirring ripples with every movement.
The two heads looked almost identical, except one had red eyes and the other blue. One radiated scorching heat, while the other exuded icy coldness. Those were likely the Dragon Beast's attributes.
A Dragon Beast with two heads was almost equivalent to two Dragon Beasts. Moreover, its aura had reached the Eleventh Heaven. With such an expert arriving, it seemed this fortress city was doomed to destruction today.
"You bunch of trash. You can't even destroy a human fortress. What use are you?" the red head said angrily. Then it opened its mouth, condensing a ball of Flame within. The fireball flashed away and struck the fortress with perfect accuracy. With a boom, the entire fortress was blasted flat, becoming a massive pit.
The attack itself was not especially powerful, but it was a blatant provocation toward the humans. Unfortunately, there was not a single person in the entire city capable of contending with this Dragon Beast. Just one of its heads possessed strength comparable to an ordinary Peak Spirit Venerable.
