With Lamiya's map guidance, the Sky Ship kept teleporting through the Underground Space, and soon arrived at a vast, empty underground plain, where a huge, brightly lit fortress stood tall in the middle of the flatlands.
Da Fei couldn't help exclaiming, "Didn't expect there to be such a huge open area underground."
Lamiya smiled, "That's why only terrain like this is suitable for building an Underground City. Besides, there are two underground rivers running through here, making it a perfect spot for a city. This city is different from Fire Cave City that has a secret mine—it doesn't have a barrier. Its greatest value is its excellent geographical location, which makes it convenient for the Hell Race to expand underground. So with the City Lord absent, the difficulty of robbing it is much lower."
