Chương 729: Sin City         

As Ren and the group approached Sin City, the stark contrast between the vast desert that surrounded it and the cobbled stone floor beneath their feet became immediately apparent. 

The transition from the unforgiving sands to the city's borders brought a sense of familiarity, a reminder of the bustling city life they once knew back home. 

However, any comfort in the resemblance was overshadowed by the foreboding atmosphere that enveloped Sin City.

"We better conceal our identities here," Ren advised, glancing around. "We don't want to draw the attention of demons and devils just because we're surface dwellers."

"I've got you covered," Vivi assured, retrieving something from her pouch that she wore as a sling bag.
