The beginners guide stated that to strengthen one's mental strength, one had to first test the level of their ability. Yao Si started with the smallest creature that possessed mental strength, for instance the bunnies in the Shadow Planet!
Yao Si focused all her mental strength, staring at the white furball ahead that was munching on the grass, following the instructions on the beginner guide and attempting to affect its external consciousness.
"Your Highness, go for it! Concentrate your consciouss—"
"You're almost there, you're about to control it!"
"Keep your breathing steady, exert your mental strength… The bunny is about to fall from your ability, Your Highness!"
"Almost there, almost there!"
"You did it! The rabbit has been chased away by Your Highness' massive mental strength!"
It was chased away by you guys!
