Speaking of bat-winged zombies, Song Jian had encountered a large number of them on a rooftop of a high-rise building. These mature bat-winged zombies were all level 10 elite BOSS. However, the place wasn't their nest, they were merely passing by.
"In another place, the theater, I defeated a sizable number of level 10 bat-winged zombie juveniles. That must be their nest. There might be a nest of mutated bats nearby. That would explain the huge presence of bat-winged zombie juveniles!" A glint appeared in Song Jian's eye as he recalled the time when he hunted the juvenile bat-winged zombies.
Back then, wiping out those juvenile bat-winged zombies was extremely difficult for Song Jian at the time. But now, let alone normal level 10 monsters, even if he encountered a group of mature bat-winged elite BOSS zombies, he would be able to compete. He wouldn't be like before, forced only to flee.
