The S-Grade queen insect had received Peter's warning earlier. Thus, it controlled a large number of mutated creatures to guard it by its side. Then, it waited patiently for its master to return.
The wait was very short. When its master's figure appeared in the cave, the S-Grade queen insect did not immediately use its control ability. Instead, it waited for its master's orders.
The sound of its master activating his ability could be heard from the dim cave. A moment later, the S-Grade queen insect was shocked to find that the smart mechas, that were continuously rushing into the cave, suddenly fell to the ground.
Then, it received its master's orders.
"Hurry up and control these smart mechas. Don't stop."
