For a millennium since the establishment of the Great Zhou Dynasty, it has always been abundant in martial virtue, and has committed acts such as city slaughter and nation annihilation numerous times. It is precisely because of such illustrious military achievements that it possesses tens of millions of square kilometers of vast territory. Yet over these years of warfare, the Zhou Dynasty has also suffered its share of setbacks. Skull Plain was one such instance, and the current Outer Sea is another.
The reason why the Outer Sea proved indigestible lies mainly in two aspects.
On one hand, the tribes of the Outer Sea are adept in warfare, with no shortage of strong individuals at the Earth Immortal Realm.
Moreover, due to the special environment of the Outer Sea, there are many Gu Insects with mysterious functions. During combat, they often exhibit unexpected effects; thus, overpowering stronger foes is not unusual, making them extremely difficult to deal with.
