Chapter 520:- Soul Devouring Spider [IV]; Three Forest Guardians

The next second she felt the roots tightening around her body, making her feel suffocated. Before she could do anything, she felt her mana was being sucked from her. She wasn't just losing a small amount of her mana each second. It was as if a dam had been broken and the water holding the dam had been released. She feared that if this continued within a few minutes, her reserve of mana will be completely sucked dry by these grey roots. 

Crack!!!

The next second, the heavy silence on the battlefield was broken by loud cracking sounds. The earth started to crack. Large fissures appeared on the ground. Seeing this everyone panicked. Even the Soul-Devouring Spiders also panicked. This also caused a small earthquake. The people inside the city also felt this earthquake.
