Wu Yijun's skill
Wu Yijun was a beautiful woman but by no means a vase that only served to display her beauty as an ornament; she was also a very intelligent and capable woman in her own right.
While she had not been useful in combat, from the first moment she was rescued from the female dormitory along with the rest of the survivors, Wu Yijun had demonstrated that even without the care or recommendation of Shangguan Bing Xue and Chen He she also had certain credibility that allowed her to participate in important meetings and contribute to decision making.
So far, the ideas Wu Yijun had put forward that had been implemented as a rule or as a push to increase work effectiveness, maintain order, or even to inflict fear and keep troublemakers at bay had not been just once or twice.
