Six years ago, Xiliang attacked the border of Jin Kingdom. General Zhou Buhui of the Bai family's army led the troops under the order of Bai Qingyan's grandfather to provide reinforcements. Bai Qingyan's father, Bai Qishan, intended to train Xiao Ruohai and sent him along. Xiao Ruohai's master, Shen Bozhong, worried about his apprentice's first time in battle, requested to accompany them.
Later, Xiao Ruohai recklessly advanced in several skirmishes, seeking to earn merits, causing General Zhou Buhui to be hit by a poisoned arrow from Xiliang. On the night before the great battle, Shen Bozhong left the camp in secret to find an antidote for General Zhou Buhui and never returned. Everyone believed he went to the Xiliang camp to fetch the antidote and was killed.
In that battle, if Bai Qingyan's father, Bai Qishan, had not arrived the next day with reinforcements of the Bai family army to take command, the outcome of the battle would have been uncertain.
