'The Dragys Lordess didn't deploy her whole force to the Untamed Jungle's outskirts. There are less than 3,000 Higher Lifeforms and only three Divine Lifeforms.' Michael sensed using the Nature Heart.
The Higher Lifeforms were problematic as most were either Tier-5 or Tier-6, but the rest were dealt with rather smoothly. At least, that would have been the case if the Dragys attacked recklessly, but that wasn't the case. They moved with great vigilance through the Untamed Jungle and burned everything to ashes, ensuring that no one could surprise attack them. However, burning everything to ashes was a slow process, especially in a place like the Untamed Jungle.
