Yang Zhenshan approached the central building while pricking up his ears to listen to the sounds around him.
There were two postal couriers talking in the gatehouse to the left, and four sleeping in the room to the right; there were six horses in the stable ahead.
Yang Zhenshan could hear the breathing coming from each room distinctly.
Indeed, such a night was more advantageous to him; darkness might obstruct sight but not his hearing.
On the contrary, the quiet environment maximized his auditory abilities.
If he were in a noisy environment, it would be impossible for Yang Zhenshan to distinguish the sounds of breathing.
A moment later, he noiselessly arrived behind the central building of the post station.
Pressing his ear against the cold wall, he carefully listened to everything inside.
Three breathing sounds.
One was very steady, seemingly asleep, while the other two were faint.
