Xie Lian is summoned by Jun Wu to the Heavenly Realm where he's informed that a Heavenly Official needs to be rescued, so he goes to the Ghost Realm, the territory of the dead.
The City of Ghost is located at 
the border between Yin and Yang,
،مدينة الشّبح كائنةٌ في الحدود بين اليين واليانغ
Sie liegt an der Grenze zwischen Yin und Yang.
Der schillerndste Ort der Geisterwelt.
Si trova al confine tra Ying e Yang,
Fica na fronteira
entre Yin e Yang,
Стоит на границе инь и ян, самое
богатое место того мира.
