In reality, both sides are descendants of the Ancient Human Race, sharing the same bloodline origin.
This is why, nowadays, within the Dongji Kingdom, as long as human forces dominate within the Grotto Heaven powers, they generally maintain good relations with the Dongji Kingdom.
After all, everyone shares the same ancestors and has the same bloodline origin, allowing them to connect easily.
As for Jiuli Grotto Heaven, since the Mao Race holds dominance internally, they have been in opposition to Dongji Kingdom for years, maintaining even cannibalistic customs.
Compared to the carefree citizens of Dongji Kingdom, Yann Xiyue and Yaoo Yexin face much greater survival pressure, especially with Blue Star's ultimate catastrophe imminent. To survive in the apocalypse, they must do whatever it takes to enhance their strength.
This is also why they proactively transferred to Linjiang First High School, seeking proximity to Huang Liwen.
