Those were Thunder Sound Bats.
With his keen eyesight, Xu Ran could make out those figures and felt slightly more certain in his heart.
Although Thunder Sound Bats were not Dark Attribute Pet Beasts, they too preferred nocturnal activities.
At this moment, they were most active.
The electric sparks that rocked the entire mountain were also a result of the Thunder Sound Bats' swift flight.
It was apparent that as Thunder Attribute Pet Beasts, they enjoyed the sensation of stirring up sparks with their movements, even actively approaching the light sparks as if to bathe in them.
Even Ziyun couldn't help feeling tempted to try when she saw the Thunder Sound Bats' antics.
It looked quite fun.
"Don't forget our main task," Xu Ran tapped Ziyun's head with moderate force and lowered his voice, "The Thunder Sound Bats possess a Two stars skill called 'Electric Sound Echo'."
