The rooftop was flat, perfect for landing a helicopter. There were no Giant Zombies here to threaten the aircraft, and with the engines now shut off, the noise had ceased, causing the zombies below to quickly disperse.
The Night Demon's Nest was in the neighboring building. They could have landed the helicopter directly on that building, but to avoid any accidents, it was better to be cautious.
There were quite a few zombies inside this building as well, but none of them were strong. Not even a single Level 3 Zombie was found, and Wang Tao and his companions easily cleared them out down to the first floor. However, slaughtering these zombies did not increase Wang Tao's HP by even a drop.
By then, most of the zombies attracted by the helicopter downstairs had already dispersed. After killing some more zombies, Wang Tao finally proceeded to the building with the Night Demon's Nest.
