Bai Ruozhu just rushed over and heard Jiang Yichun call out "Senior Brother," which surprised her. Wasn't Jiang Yichun's senior brother Wei Guanyu supposed to have died early?
Back then, Wu Yunfeng had taken in three disciples; the eldest was Wei Guanyu, the second was Xu Huilin, and the third was Jiang Yichun.
Wu Yunfeng wanted his daughter to marry one of these disciples. While Wu Wanqing told Jiang Yichun that she liked him, she chose Wei Guanyu instead. This was quite an unpleasant matter for Jiang Yichun during his youth.
However, many things happened later, and Jiang Yichun and Bai Ruozhu gradually unraveled many mysteries, including that Wu Wanqing had once used a forgetfulness poison on Jiang Yichun.
And that Wei Guanyu didn't die accidentally back then, but was killed by Wu Wanqing.
