Void formation

The moment yohan and Natasha left the forest and took their first steps on the ground something unexpected happened, the whole surrounding started shaking violently, the surrounding weather started changing drastically, Yohan and Natasha felt a chilly sensation in their spine, both of them become shocked seeing sudden changes in their surrounding, a few moments before everything was okay.

Ding,

[you activated void formation]

"Void formation what the hell is that mean"yohan mumbled as he heard that notification in his mind and looked towards the ground, this place is somewhat different, the ground here in this place is more hard and sturdy compared to the forest where they spend their last few days, this place is looking completely different and there might be some formation existed in this place which they activated the moment their foots landed here.
