Before he came, Gu An had used his Divine Sense to observe that the strongest person on the island was slightly stronger than a Divine Soul True Monarch, but not by much. If there were Celestial and Earthly Immortals present, he wouldn't dare to come.
With Celestial and Earthly Immortals, there could be even higher realms.
If the openly strongest was only a Wandering Immortal, then it probably wasn't likely that there were beings more terrifying than Celestial and Earthly Immortals hidden away.
Even if there were, as long as Gu An didn't stir up trouble, there wouldn't likely be any problems.
He came to the Sea Guard Mansion in the city to trade, and needed to register an Identity Token to enter various buildings, according to the information he had obtained through his Divine Sense.
The Sea Guard Mansion was huge with many Cultivators coming and going, covering an area of a hundred li. As soon as Gu An entered, a young servant came up to him.
