These monsters, these living dead, are externally strong, possessing remarkable strength and agility, but internally they are a desert, with only the residual, instinctual craving for blood meals.
They had devolved from humans to beasts, relying not on thought and intelligence, but on the power of their bodies.
This caused everything about them to be like a castle built on sand, hard encounters naturally resulting in headaches and bloodshed, but as soon as one targeted their loose foundations, one could easily destroy the apparent sturdiness and fierceness.
Li Xu's use of mental shocks each time wasn't much, yet they were like invisible, sharp knives stabbing into the heads of the monsters, whose meager spirit possessed neither resistance nor defensive power, thus it was as effortless as a knife slicing through butter, a stark contrast to the earlier difficulties.
