Zhou Yu, in truth, is quite cautious, but you can't expect a person who has been in the South for years and has barely come to the North to understand the Northern Barbarians' way of scouting with eagles.
Li Yan, who was also sent to complete this task, is also quite cautious, but the problem is none of his precautions accounted for aerial reconnaissance. For someone like Li Yan or Zhou Yu, who has largely been in the South, this is something they have never encountered.
This led to the situation where, although Zhou Yu and Li Yan were very vigilant, they were actually already exposed and unaware of it.
"General, there's a group of about thirty Miscellaneous Huns rushing towards us," a scout hidden in the grass carefully reported to Li Yan.
"Hmm, directly towards us?" Li Yan asked after a moment of silence.
"Yes, there's no sign of determining their position, yet they are coming straight at us," the scout replied truthfully.
