Ning Cheng's Divine Sense swept out like a blanket covering the sky, rendering all surrounding prohibitions useless against it. However, he saw no trace of Ning Ruolan, nor did he see the Helian Dai that Lu Yu had spoken of.
Ning Cheng entered the commerce building Lu Yu had pointed to. It was bustling with people, clearly indicating that the business was doing very well. It was an establishment that purchased spiritual grass and sold Dan Medicine.
"Call out your shopkeeper," Ning Cheng said as he pushed his way through, parting the crowd at the counter. The trail of Ruolan ended here, and Ning Cheng did not have the patience to wait in line.
Most people here were solitary cultivators, and none wanted to cause trouble. Carrying a slight murderous aura, Ning Cheng didn't even need to take action; the cultivators at the counter automatically made way for him. Some of the more timid cultivators began to back out.
