The Sandpeople didn't do much circumventing, hence it was very straightforward for Du You to locate the secret chambers in the City of Sand People. Truth to tell, they had learned the art of building these secret chambers from humans- initially, they didn't even have such a concept.
The chambers were simple, located below the residence of the city lord, typically an ordinary cellar.
The treasures stored here were the wealth accumulated by this city over the years.
"This is the place, right?" Du You said, standing before an iron door amidst a heap of cleared rubble. The door was discovered by Death Scorpion, but it didn't dig further, fearing it might collapse the cellar.
Besides, this place was the sole underground room in the vicinity. Du You couldn't fathom any other plausible places for the loot to be hidden. As for the lock on the door, it was negligible to him.
