Firstly, Liu Xue's status offered a layer of protection for Mao Caiwei. Mao Caiwei, a mere outer sect disciple, was vulnerable to Ye Fan's influence within the Azure Peak Sect.
With Liu Xue, a core disciple of the Jade Lotus Palace sect, by her side, Ye Fan would be less likely to attempt any brazen maneuvers against Mao Caiwei.
After all, an overt attack on Mao Caiwei while Liu Xue was present could easily escalate into an inter-sect conflict, a risk Ye Fan wouldn't readily take. Additionally, Ye Fan remained blissfully unaware of Liu Xue's connection to Wang Li, further diminishing the threat of immediate action.
Secondly, as Wang Li had subtly explained, Liu Xue's presence served another, more clandestine purpose. While Mao Caiwei sought out her former sect sisters, Liu Xue was tasked with keeping a watchful eye.
