Alex knew he had to keep walking if he wanted to find the treasure so he kept looking for it, following the clues, for days and days, until then a bunch of weird guys came, but they were different. Their clothes, the way they talk are different, and it appears that they are also searching for the treasure so that they can bring back the treasure of their family, unlike Alex he wanted it for himself so that he could prove to them that he is great and can discover the hidden treasure. They wanted to murder him at first, but the group's leader refused because he wanted to help, and after one night of working together, they discovered the treasure, of which Alex carried some to town. And received a certificate for discovering the secret treasure, becoming extremely well-known. So he proved them wrong by doing what he wanted, and the weird group bought back the family treasure.
Based merely on "out of water," this is a prepositional phrase.
Explanation:
"Out" is an adverb (an adverb asks what, where, when) because out answers the question of what. "Of" is a preposition and "water" is the object of the preposition.
