Nie Yan and Tang Yao entered the building. The building's earthen walls were full of cracks and looked like they could collapse at any moment. Several NPCs stood inside dressed in various desert dweller outfits, their faces covered with cloaks. They sold a variety of items and materials, all special products from the desert.
Nie Yan led Tang Yao past these NPCs, walking deeper inside. They reached a secluded corner and pushed open an old wooden door, revealing a narrow tunnel leading underground. Nie Yan carefully walked down.
"What are we doing inside?" asked Tang Yao, puzzled. The tunnel was dim, and he couldn't see the path beneath his feet, so he could only follow Nie Yan by feeling.
The dark, narrow passage, with no indication of where it led.
