Zhao Xu knew very well that nothing like this had ever happened in his previous life. The undead tide was indeed extremely terrifying. They were like white ants that could eat away at anything that stood in their way, and once they got caught up in the undead tide, it meant that the entire camp would be destroyed.
For example, one would become a 'zombie' within a few days after being killed by a devil soul corpse.
Any humanoid creature that was killed by the fear chestnut bind will become a new 'bind' after a few rounds.
the humans killed by vampires would also turn into " blood-sucking derivatives. "
All sorts of things.
If they were not careful, a powerful undead creature might enter a group of humans who had no ability to fight back. When they saw it again half a day later, it was likely to be a whole nest of undead creatures.
