After returning to the Divine Realm civilization, Han Wu immediately sent a message to Long Xiang of the Ancient Dragon Tribe, indicating that he had safely returned from the dragon race.
This action wasn't because he had a particularly good relationship with Long Xiang, but because he had no way to contact Long Qi. Sending the message to Long Xiang was merely to have him pass it on.
Upon receiving Han Wu's message, Long Xiang reported it to the clan leader of the Ancient Dragon Tribe, Long Lie, who then passed it up the chain to inform Long Qi. When Long Qi learned that Han Wu was safe, he let out a long sigh of relief.
He then summoned Long Xiang to inquire about the various events that had occurred within the dragon race during this time.
