If Xiang Kun hadn't spotted that mutated big bird from a distance on the plane yesterday, he wouldn't have associated it with a mutated bird when Chu Xiuwen and others discussed this incident.
Just as ordinary birds seldom attack humans, the probability of mutated birds attacking humans is very, very small, especially in a crowded, daylit tourist area like this.
At least from his experience, both the giant owl and the mutated spider have a strong sense of wariness and fear towards human society and consciously avoid crowds, which is one manifestation of their increased intelligence.
However, based on the time and area where Xiang Kun saw that mutated big bird, there indeed is a possibility that the mutated big bird appeared in the Wushu Mountain Scenic Area this morning.
If it really was the mutated big bird, it must have risked appearing in front of humans for some unavoidable reason.
Of course, there is a greater chance that those were just ordinary eagles or birds.
