Mourning howls rose, and twelve zombies were all stopped by this bolt of light. Every zombie's body couldn't stop twitching, with lightning flickering on them.
Light attributes indeed cannot restrain these special wraith entities, but thunder attributes seem capable. Under the pressure of thunder, these copper-green zombies revealed extremely pained expressions and were desperately struggling.
The Spirit Furnace Academy students present all had insightful eyes, from the speed and explosive power of these copper-green zombies earlier, they could vaguely judge that these should at least be of the 4th Rank, even possibly the 5th Rank wraith entities. They were much stronger than the wraith entities that had appeared before.
Yet, Tang Leiguang managed to halt these wraith entities by himself. What terrific explosive power that was!
