The distance was rather far, so nothing could be seen clearly; now, as Xu Ran and his three pet beasts arrived at the foot of the mountain, he could make out more details.
On the jagged rocks, bolts of lightning would crackle from time to time.
And under each flash of lightning, one or two slender, thin figures would faintly appear.
They were Thunder Sound Bats.
With his keen eyesight, Xu Ran managed to see those figures clearly and felt a little reassured inside.
Although Thunder Sound Bats were not dark attribute pet beasts, they too preferred to be active at night.
Right now, was when they were most energetic.
The lightning that crackled across the mountain was caused by the rapid swooping of the Thunder Sound Bats.
It was obvious that, as thunder attribute pet beasts, they enjoyed using their movements to stir up bolts of lightning, even actively plunging themselves into the lightning as if bathing in it.
