章 578: Chapter 321: Sword Qi of Immortal Slaughter, A Million Demonic Beasts_1

Boom boom boom~~

Not long after, an enormous army of the Demon Clan flew towards the Tri-Star Island Group. A formidable and frightening aura erupted from them, darkening the sky above, creating an effect like the shroud of nightfall.

Countless Sea Clan monsters swarmed on the sea too.

A rough estimate put their number to over a million.

Of course, the primary force was the Thunder Hawk tribe.

They soared in mid-air, tearing through the sky like supersonic jets. Their bodies would occasionally emanate streaks of golden lightning, accompanied by an ominous aura of destruction.

Although their numbers were only in the tens of thousands, each one of them was at least a second stage monster, and some were even third stage monsters.

Even a single Thunder Hawk's combat power far surpassed that of other monsters.

Naturally, the grand scale of this assault force was detected right away by the human cultivators of the Tri-Star Island Group.
