章 447: Chapter 277: The Fourth Brood Nest! The Expedition (Extra 12)

The Rob Sea Star Realm is not particularly vast.

During the inquiry of the Seven Star Civilization, the largest explored range exceeded thirty thousand kilometers.

However, decades of relentless effort and massive resource investment have only led to the establishment of an outpost base within about three thousand kilometers of the star realm's entrance.

Further in? The Seven Star Civilization has only been able to dispatch small squads for exploration, struggling to establish a solid base.

The most significant reason for this is the obstruction of the Cloud Beast Civilization.

This foreign civilization, as one of the earliest to enter the Rob Sea Star Realm and the first to invest massive resources, built numerous mother nest lairs, enabling it to maintain a strong offensive against the Seven Star Civilization.

About eight thousand kilometers away from the Seven Star Civilization's nearest outpost base, there is a continuous mountain range.
