The eight top Immortal Emperors in the current Immortal Realm are all experts proficient in the Array Path.
The Palace Master Hall where the Golden Crow Immortal Emperor resides is similarly surrounded by formations personally arranged by him, which are quite intricate and exquisite. Even if the other seven top Immortal Emperors were to come, they wouldn't be able to uncover it in a short time.
It is for this reason that the Golden Crow Immortal Emperor has peace of mind leaving Golden Crow Palace.
Several days after the Golden Crow Immortal Emperor left, Fang Bai, who had been lying dormant and undetected, went alone to the back mountain and entered a cave with a Concealment Formation. He declared to the outside world that he wanted to go into closed-door cultivation, but in reality, he was preparing to implement his plan to rescue Linghu Qianjiao.
