The total number of demon cultivators on Zixuan Island is only over five thousand, and with this mobilization, only a thousand demon cultivators remain, with the First Island Master, Lion Heart, personally overseeing the island.
In fact, if not for the concern that Lu Ye might have doppelgangers lurking on the island without appearing, Lion Heart wouldn't need to stay behind at all. With the strength of Zixuan Island's protective array, no force in the All Phenomena Ocean can shake it, so even without a Moon Jade governor, there's no risk of it being breached.
