After annexing the territory of the Skeleton Tribe, Zhou Tian's Beastman Clan had improved immensely. However, they had yet to fully digest these gains. Additionally, the Undead Monsters were extremely powerful. In the end, Zhou Tian's Beastmen were defeated not long after the battle began with these Undead Monsters.
Indeed, one could say, given the strength of Zhou Tian's Beastmen, they were crushed upon contact when they faced these Undead Monsters. The power gap between the two sides was too big. If the strength of Zhou Tian's Beastmen was between level twelve and twenty, according to the monster rating system, the strength of the Undead Monsters was at least level twenty.
In such a situation, the defeat of Zhou Tian's Beastmen was inevitable. As a result, the second layer of the Skeleton Cave that they once occupied was lost to the Undead Monsters after their invasion.
