Using the Crystal, the City Lord's wife personally created the Identification Badge for Xu Shan. The Badge held the false details that Xu Shan forced her to use.
With the Badge in hand, Xu Shan now had the means to enter restricted areas within the Teleportation Zones all throughout the Kingdom. In fact, he made his badge one of the highest tiers, so that he could pass through many unnecessary troubles along the way.
The Woman thought about trying something to make trouble for Xu Shan. However, she dropped the idea and didn't mess with the badge, at least not to the extent that he could notice.
The only thing she did was to leave a small thread in his badge which she could later use to locate him. Even with the knowledge, it was impossible to locate that tracing thread in the badge.
"I did as you asked. You can leave now," she told Xu Shan.
