Being chased for their lives

Because Third Mo had already finished up his business there, Sima You Yue and the others planned to head to Prime City where Xuan Yuan Pavilion was holding its auction. 

Prime City was Northwest of Shandong City. It happened to be in the middle of West Moon City and Prime City. As such, she thought of a way to say her farewells to Bei Gong Tang and the others before heading to Prime CIty.

Sima You Yue and Ximen Feng would have motion sickness taking the teleportation array. However, because Prime City was rather far away, they wouldn't be able to reach there in three to five days. As such, they had no choice but to take the teleportation array.
