"Why did you come back so quickly?" Jing Wuming noticed that Ning Cheng had returned shortly after leaving and realized something must be amiss.
"If I've raised the money, why not come back? We're leaving the city now," Ning Cheng signaled to Jing Wuming with a hand gesture.
Jing Wuming quickly grabbed Ning Cheng, "You've raised the money, let's hurry to the slave market. Why leave the city?"
"Didn't you say the slave market is at night? It's not dark yet," Ning Cheng replied.
"Then why are we leaving the city?"
"You'll know once we're out."
...
Three hours later, Ning Cheng and Jing Wuming hurried back to Xuan Jade City. Jing Wuming finally understood what Ning Cheng had done outside the city; Ning Cheng's proficiency in array formations was remarkably high. He had set up seven or eight arrays close to the ninth level, including trapping and killing formations.
