As the name suggested, the Immortal Welcoming Hall was the place where the Heavenly Courts welcomed guests. It was located in the inner part of the Middle Heavenly Gate.
The Immortal Welcoming Hall was mainly used for receiving the famous Itinerant Immortals of the Primordial World who had come to seek refuge with the Heavenly Courts. Occasionally, it would be like this, as the place where the righteous gods of the Heavenly Courts would officially meet the Itinerant Cultivators.
The definition of itinerant cultivators was different. In the Primordial World, there were many independent Qi Refinement Warriors who did not have any sects to rely on.
In the Heavenly Courts, those who did not enter the Heavenly Courts' immortal records could be treated as itinerant cultivators.
