Chen Fei's face slightly changed, his figure flickered, and in an instant, he was already hovering above Thousand Geese City.
Zhao Ruizheng and the others also appeared one by one. They couldn't help but turn their heads towards the direction of the Sacred City's walls, where a crimson light was blazing, piercing through the clouds.
"Activate formation, move out!" Chen Fei commanded, flying towards the direction of the city walls.
The bells tolled, and the walls glowed red, signaling an urgent situation at the Sacred City's defenses.
According to the Sacred City's rules, at times like this, anyone within the Mountain Sea realm inside the city must unconditionally go to defend the walls. Even if you're in seclusion preparing for a breakthrough, you must set aside your endeavors.
Truly, if the Sacred City walls were breached, seclusion would become a dead end. It was better to block the enemy outside while the walls were still intact.
