"Is this because his corpse was taken away, so some kind of balance was broken, and it started coming back to life?"
Colin stood up, his eyes on the things above his head.
It was at this moment that a larger "cocoon" cracked open, its shell made of tree roots, followed by a stream of blurred humanoid smoke that burst out quickly and attacked him.
Without any courtesy, he waved his hand and conjured a thick wave of flames.
As he had expected, just this one move should have been enough to severely damage that thoroughly contaminated humanoid monster...
But to his surprise, the smoke didn't disperse when it met the flames; instead, it let out a scream.
Immediately after, a figure was forced out from the smoky state, its head and limbs were shrunken, but its belly was hugely swollen, and there was a large vertical mouth on its stomach, starting from the belly button and split open...
This mouth sucked in violently and actually devoured some of the bonfire.
