In front of the Main Gate of the Sky Capital City, a keyhole could be clearly seen. Yang Chen took out the prepared key and inserted it directly into the keyhole.
With a click, the gate of the Heavenly Capital City opened.
Excitement appeared on the faces of Yang Chen and Jiang Caiying. However, the next moment, their excitement froze. Because, when the gate of the Heavenly Capital City opened, a sudden rumbling sound arose, and then the entire city moved upwards into the sky.
This forced Yang Chen and Jiang Caiying to quickly retreat, looking at the majestic scene before them but unable to feel any joy.
As the Heavenly Capital City moved upward, it signified that the moment they used the key to open the gate of the city, the Heavenly Capital City, as a symbol of the inner area of the Emperor's Treasure, had gradually emerged from the water, coming into everyone's view.
But that wasn't the most important part.
