Coldfrost Citadel

When the astrological card in White Flame's hand lit up, Coldfrost Citadel hidden in the gap of space and time began to reveal itself. Ice walls that looked like blades and fangs began to rise on the empty ice sheet. Translucent phantoms appeared in the distant night sky like a mirage and quickly materialized under the starlight before turning into towering walls and pointed towers. As Hao Ren drove forward, the surrounding light and shadow continued to change. The scene alternated between the Arctic ice sheet and the Coldfrost Citadel, which made it almost impossible to distinguish illusion from reality. When it all finally stabilized, they had arrived in front of the demon hunters' "millennium palace", which greeted its visitors with its magnificent appearance.
