When Niken and Richard performed the lifetime contract ritual, they never thought that the portal door connected the dark realm to the mortal realm was shattered.
The Beastmaster looked at the portal door with a terrifying gaze but did not prevent several dark beasts from leaving the gate. A lot of dark creatures were excited to come into the mortal realm and ate humans. Even though Zen wished to prevent it, he couldn't.
"We have to defeat the black knight to get to our fullest strength." the black Supreme Alpha couldn't wait to rip the tiny white cub that never left the black knight's feet.
"I think you're right. But I wonder what broke this vortex? Even though I can't control this vortex anymore, this portal door can't possibly be destroyed without reason.
The black Alpha raised its muzzle as it smelled a strange odor in midair. "Someone's coming."
Zen immediately activated the invisible shield so that no one could see him or notice his presence.
