The mission to the Jade Ant Nest was for Klaus to lead Rory, Omen, Slate, and Echo to retrieve a drop of the Immortal Essence water that was known to have existed in the Jade Nest when the Jade Ant Queen was alive.
If they manage to get their hands on it, it would greatly help Lord Victor in forming his 10th immortal ring.
That was the main mission objective.
However, Klaus had side missions, and one of them was to find a way to add more Ant Queens to Asha's Legion of Ant Soldiers.
Granted, he had no idea how Queen Mantis died, so he believed he would be able to get his hands on some Ants that may still exist inside the Nest.
Unfortunately, that wouldn't be the case since the Heavens Court had already slaughtered her and her children and even buried the reason, so nobody was aware they were involved.
Now, however, he had something even better.
