Cheng Susu and Zhou Chen know the paths well; if they took the wrong route, it would surely arouse suspicion, particularly since Zhou Chen and Li Shentong don't get along.
Earlier, when she returned with the disciples of the Cyan Cloud Sect, she piloted the flying ship swiftly through the sky, not paying attention to the route.
As long as she searched carefully, she would surely find traces.
If Li Shentong changed direction midway, it would cause a conflict with Cheng Susu and Zhou Chen.
However, Cheng Susu's strength was inferior to Li Shentong's and she was unprepared.
Facing an abrupt attack from Li Shentong, she would probably suffer a lot.
Even if Zhou Chen were stronger and deeply hidden, at his age, he could at most reach Body Refining of over a dozen turns, at best comparable to the weakest Divine Form Realm.
Facing a powerhouse like Li Shentong at the Peak of Divine Sea Realm, an exceptionally strong figure in the sect, he stands no chance.
"Li Shentong, damn you!"
