Hmm...
As soon as the Heavenly Emperor spoke, the Four Heavenly Kings fell silent.
Despite their earlier uproar, none of them were willing to descend to the mortal realm. Regardless of potential risks, besieging Vermilion Bird City was a demanding task under scrutiny from above; there could be no deception or sloth.
The troops under the Four Heavenly Kings were elite units loyal only to them. According to future plans, Heaven's Court would inevitably be temporarily abandoned. Should a Heavenly Demon invasion overwhelm them, the troops would be their assets in future ventures beyond heaven—shedding them would be out of the question.
"You want to sit back and watch at this hour?" The Heavenly Emperor sneered, "Don't forget, if your stationed troops can't take the foothold below, you're willing to use them to slog through against those Heavenly Demons here?"
The Four Heavenly Kings flushed red upon hearing this.
