Dracula patted the dust on her body, glanced at the information sent by the Geological Bureau, pondered for a moment and said: The main reason is that the terrain has changed.

The landform has changed? Chu Yu looked confused.

Yes. Dracula pointed his fingers around: The place we are stepping on now is at least ten centimeters more than what is shown on the geological bureau data. Apart from that, have you not noticed that the surrounding trees and flowers grow very quickly?

Chu Yu: That's four circles!
