The Imperial Palace, Imperial Observatory.
This place is not a palace, but a Pocket World created during the first Heavenly Tribulation—the One-Star Heavenly Tribulation. Every subsequent Heavenly Tribulation has descended within this Pocket World. At this moment, every member of the royal family, along with the civil and military officials and their descendants, has already entered the Imperial Observatory. This was a promise Long Zaitian had made long ago: to allow the entire younger generation to face the trial of the Heavenly Tribulation together.
"Your Highness, Crown Prince, Chu Xuan has entered the palace."
