"The Wan family may no longer be fitting suspects, but that still doesn't explain how or why both Bai Chen and Jiang Hao disappeared within their territory," Yang Qing muttered as he shifted his posture, leaning back in his seat.

Analyzing that information, with the Azure Sapphire Kingdom as the common denominator in their disappearances, it was natural to suspect the kingdom.
