Only other living beings who were not native to this lake could not use their abilities once they went too deep into the lake.
Ainsley didn't know that others could not even use their abilities that could be seen with the naked eye.
Ainsley could use her love virus only because her ability was invisible to the eye.
The water of this lake did have a problem and Ainsley also had a hunch that maybe, just maybe...
There were beasts and monsters here who could devour special energy, draining the energy of any ability users which was why the ability users could not use their abilities.
Ainsley tested another batch of monsters and beasts to test her hypothesis and she had to wait for a full ten minutes to finally find some strange water monsters and beasts who devoured special energy!
