Despite the fog in this small dimension, it was as if the Flame Wing Centipede has eyes everywhere. After the 4th rank centipedes fused and became a single 5th rank magic beast, it continued on its way to reach Rezen that was busy taking two gold coins on a floating island
The breaking of his spell naturally alerted Rezen and after he stored the gold coins, he look in the direction where the centipede was coming from
Szzz!!
Some of the fog dissipated as tens of balls of fire flew in the air, all of which were released by the Flame Wing Centipede
Since this entity is now a 5th rank magic beast, despite the fact that Rezen could still defeat and kill it, things wouldn't be as easy
Aside from that, even if he did kill the centipede, since killing and sealing wouldn't work then there is only one thing he could do
"[Earthen Projectiles!]"
Magic circles formed on the floating islands surrounding Rezen and they moved according to his will
