Bay Domain's army rapidly advanced underground, expanding the underground space and exploring more Resource Spots.
They were always busy, not only the Bay Domain Soldiers but also accompanying engineering troops and staff.
Compared to the cautious progress on the surface, the Bay Domain's movements underground were much more uninhibited.
Various magical creatures and cavern monsters along the way were driven away in advance to prevent them from attacking, and thereby avoid costless dying.
The vast underground space contained many resources and wealth.
Along with the influence of Elemental Tides, the metal veins and Magical Material were easier to extract compared to the Material Plane.
During their advancement, the Bay Domain conducted relatively detailed explorations, recording valuable areas for staff and Adventurers to handle meticulously.
In just five days.
They had advanced over 300 kilometers.
