Those are Thunder Sound Bats.
With his keen eyesight, Xu Ran could make out the figures, his heart settling a little.
Although Thunder Sound Bats aren't Dark Attribute Pet Beasts, they also like to be active at night.
Right now, it's when they're at their most energetic.
This surging electric light covering the mountain is also caused by the Thunder Sound Bats swiftly darting through the air.
It was obvious that, as Thunder Attribute Pet Beasts, they really enjoyed stirring up electric flashes with their motions, even actively diving into the lights, as if bathing in them.
Even Ziyun, seeing the Thunder Sound Bats' actions, could barely hold back from wanting to try it out.
It looked like it would be a lot of fun.
"Don't forget why we're here." Xu Ran knocked lightly, yet firmly, on Ziyun's head and lowered his voice. "Thunder Sound Bats have a two stars skill called Electric Sound Echo."
