The flying black creatures were also very large, at least a few dozen meters long. They were all covered in thick black armor, and held black sickles in their hands. Blood dripped from their fangs, adding more emphasis to their already horrendous appearance.
The moment these monsters appeared, they immediately attracted Shen Fei's attention. He would have to be blind to miss them.
Shen Fei gauged that the swarm covered an area of a few thousand meters, maybe even tens of thousands of meters.
"What... What the hell is this?" He had never heard of these bird-type monsters before. Furthermore, they do not look weak! 'How was this place formed?!'
Shen Fei's heart was filled with doubt. Although he had seen many things, this was the first time he had encountered such a monster.
Moreover, the spiritual Qi in this place was quite strange. It was much thinner than the outside world, like an abandoned space.
