"The place where we live, everyone should have learned about in high school. The territory of Jiuzhou is like an isolated island in the endless wilderness beyond, and we live only on this small island. No one has yet been able to figure out just how vast the land beyond the wilderness is, for those who venture too far from this island rarely return."
"Our territory is frequently assaulted by beast tides. Desolate beasts from the wilderness often riot and sometimes gather in certain places, battering the defenses of Jiuzhou, attempting to break through."
The last major beast tide outbreak occurred six years ago. The entire boundary of Jiuzhou was completely surrounded, with several breaches in the boundary defenses, resulting in heavy casualties.
