Snow Maiden and Dongfang Hongyue had agreed on a prisoner exchange, but in fact, this statement wasn't quite accurate.
The ones Dongfang Hongyue's group had captured were indeed prisoners, who had been overawed by the might of Lin Yu on the battlefield; they, in reality, were all warriors.
Whereas the people captured by the Grassland People were all civilians.
For the sake of getting the people back, Dongfang Hongyue did not pay much attention to these details.
Upon returning to the military formation, Snow Maiden saw that both Zhang Ling and Huyan Jue had already returned.
With the current combat power, a forceful attack on Mountain and River Pass was also possible.
However, the Mountain and River Pass was protected by a Formation, which could not be broken in short order.
