Even if we take a step back, if the Demon Clan's Heavenly Court really cannot hold out until the completion of the Two-World Passage, Sun Wukong can only make the painful decision to stop the development and stabilization of the passage. This would allow the Quasi-Saint Realm powerhouses of the Demon Clan's Heavenly Court to first pass through an unstable temporary passage to the Three Realms. As for the remaining powerful figures, we'll have to wait until a Boundary-Opening Orb is found to create a passage.
Unlike in the past, Sun Wukong is now the master of the Heavenly Que Realm, with complete control and rights over everything in the Heavenly Que Realm. Within this realm, it's impossible for there to be only one Boundary-Opening Orb. A careful search should yield more, but this would render the past half-year's effort meaningless, and everything would have to start anew.
"You've been prepared for this all along?"
