The flying mutated creatures were the first to charge into Crystal City.
From afar, these flying mutated creatures looked like raptors with wingspans exceeding two meters, with some even reaching four or five meters.
Fortunately, Xu Xin didn't spot any existence similar to the previous pterosaurs among this group of flying mutated creatures.
Judging by this, there shouldn't be any advanced mutated creatures in this beast swarm.
At least not yet.
This is good news.
Because at this level of beast swarm, they are fully capable of holding their ground!
"Everyone, pay attention to the sky, flying mutated creatures have entered Crystal City and are about to approach!" Xu Xin announced to the group.
The situation on the ground wasn't optimistic either.
The beast tide that originally surrounded the outside of Crystal City has completely surged into the city,
and on the map in his mind, areas of Crystal City were entirely enveloped by red dots!
