This is the Cloud Light Realm City.
"This city is an extremely powerful Heavenly God Artifact, containing numerous formations within."
"From today onwards, you all are to comprehend the formations of this city. Be sure to fully master all thirty-six formations," Li Yuan said in a deep voice.
"Yes." Over ninety Heavenly Divines nodded in agreement and, under the leadership of Xuan Yang Heavenly Divine and Ice Ming Heavenly Divine, entered the Cloud Light Realm City to study and comprehend the internal formations.
Li Yuan was satisfied with this.
"Once they are familiar with the Cloud Light Realm City formations, and when we reach the Divine Realm, the city fully unfurled can be defended by just thirty-six Heavenly Divines working together, enough to withstand the joint attack of multiple Divine Monarchs," Li Yuan thought to himself.
He had long considered how to employ this group of Heavenly Divines.
