This is the map Lu Chan submitted to me earlier, marking three suspected branch bases.
At first glance, Lu Chan's list of suspects seems shorter, as if he has delved deeper than Liu Shuying, but the areas marked on the two maps mostly do not overlap. This might be unavoidable, as Ming Zhuo himself is inherently suspicious, making all associated branch bases appear suspect.
One of them used social networks for the investigation, while the other likely used the powers of Impermanence; hence, their standards and directions of suspicion differ, but it's like devouring from two ends of the same line, eventually converging at the same point.
Both Lu Chan and Liu Shuying insisted that there is definitely one real "culprit" on their lists, and there's one overlapping mark on both maps. I think the location we need to focus on is this one.
