The old Taoist was no fool. He was aware of how competent his enemy was, that he was not rendered completely useless even after being caught by the immortal binding rope. Although he was sent away by the little fox's spell it wasn't possible for him to stay afloat forever. Hence, the old Taoist decided to use his 'Rise of Insects' to summon all bugs within a ten-mile radius, whose only mission was to devour every single living thing they saw.
Be it human or beast, no one could escape the insects' wrath. Once the poisonous bugs consumed Curator, the immortal binding rope would fall to the ground. The old Taoist would be able to regain control over the rope again if he was within a certain distance.
This was the countermeasure he figured out in this moment of desperation.
