Both of them looked up to be surprised by the dark clouds that had gathered above them.
As for the booming sound, that came from the thunder and lightning that was currently
running through these clouds.
However, what confused them was that this was heavenly thunder, the kind that only fell when one broke through into the Soul Realm. There was no way that there was someone breaking through in this kind of place, so why was there heavenly thunder gathering?
The stranger thing was that the heavenly thunder was gathering right above Fei Jun.
Fei Jun could sense the danger coming from it, so ignoring Lin Fan, he immediately turned to run away.
But before he could run, the first bolt of heavenly thunder fell down on him.
