Lu Shu knew that a war might occur here, but he did not expect it to come this quickly!
He looked at the quivering arrow and tried to estimate their power. Although the walls of the mud brick house were weak, not everyone would be able to shoot an arrow through. After the black arrow pierced through the walls, it could hit the kang and still have surplus energy.
Before Lu Shu could finish analyzing, Zhang Weiyu suddenly said, "It's a Rank Four expert from the Black Feather Army. The arrow came from the northwest direction. They should be the first batch of scouts. They came from the mountains. Under typical circumstances, scouts from the Black Feather Army are made up of one Rank Four and four Rank Five soldiers. They are all elites of the army!"
