The art of war prioritizes winning hearts over conquering cities. If the people's hearts remain unchanged and social order continues, that's the best outcome.

"When the army enters the city, they must not disturb the people, nor trespass into civilian homes, rob or harm lives. If anyone does, they will not be forgiven lightly," Ye Shikai ordered.
