The reason for holding the Demon Gathering in the Kneecap Desert this time is to gain the support of undead creatures.
The difficulty lies in the absence of similar types of beings among the extraterrestrial fierce beasts, making communication with these desert lords troublesome, as there's an innate distrust, causing them to expend a lot of energy in the desert.
As a result, there was insufficient attention to overseas affairs, leading the Sea Clan to be somewhat disunited; ultimately, it's because these visitors lack diversity, with a scarcity of undead types and sea demon types. Basically, every extraterrestrial fierce beast arriving here is either a land or sky demon beast, which is unavoidable.
