Feeding It With Poison Essences

"Sigh... Looks like one Peak-Level Earth Grade Poison Essence isn't enough..." Davis became a bit disappointed as he floated in the skies over the darkness.

The Pestilent Dragonfly Dust Spawn didn't reach King Grade! That made him sigh even after he gave Natalya his word that he would try to stop sighing all the time.

He sent another Poison Essence, the Haze-Loving Lavender Beetle, a High-Level Earth Grade Poison Essence, one level lower than the previous one, hoping that it would be enough to make it step into the next stage. 

Its appearance looked like an adult palm-sized insect. It didn't look harmful at first glance, and even its presence was not big, but its description said that its bite could even cause humans to be infused with both a dormant poison and an aphrodisiac, with the latter being more potent enough to send the victim insane rather than horny.
