Xiao'er knew that Shangguan Xuanyi was under great pressure. In reality, it wasn't quite the right time to attack Nangong Country, as Minze Country had only just begun to develop. If they failed, returning to their original state would be the best outcome, the worst-case scenario being the extinction of their country due to a careless mistake.
