Yan Liqiang recalled hearing about the uprising of the White Lotus Society in the Heavenly Realm before. It was extremely chaotic, especially in the Qu, Huang, and Yue Provinces. Not only did the White Lotus Society breach the city, they also massacred the local influential clans. Any imperial court officials who fell in their hands couldn't escape. Many of the officials from the three provinces were killed by them...
Since Sun Bingchen was going to Yue Province to perform his duties as the provincial governor, Liang Yijie would probably follow him there too. That'd be no different than venturing into the lion's den. Naturally, Yan Liqiang was quite worried about them.
