Lu Zhen's ears twitched as he had a classical smile on his face, hearing these old men arguing about the same topic again and again.
"What's the point of the argument, as in the end, someone has to do it," he mused with hints of annoyance.
"So, what should I do with these old guys…" His face remained expressionless as he looked at the map made with leather from some unknown animal in front of him, featuring various colours. However, the mark of the river was in red, making it highly contrasting with the background.
Basically, the problem was that due to the deep river, these passes to reach the Xia family were challenging. Since it was surrounded on all sides, you couldn't just go around.
