After leaving the forest with everyone, they've returned to the base only to be welcomed with zombies blocking their paths. The number of zombies isn't much but it easily passes hundreds in counting.
Thankfully, they didn't ride in their car and flew over instead by using the phoenix and two golden eagles as the mount. The rest of their tamed beasts were temporarily put inside Xueya's dimensional space. After mutation, the size of each bird enlarges enough to compete with a small jet plane. This is especially true when it comes to the size of the mythical bird phoenix.
In the beginning, everyone thought they were seeing things, with the difference of height of the sky to the ground all they could only see at the beginning were countless moving black spots. Only when they've lowered the altitude of their mount's flying space that they've seen their base destroyed and zombies roaming all over.
