Passing by Guangxin Palace, Fan Xian saw a man in black robe following a female official inside. He couldn't bear his curiosity and followed him, and found that the man in black robe was actually Zhuang Mohan.It turns out that Zhuang Mohan and Sean are brothers. He was trapped by family ties, so he had no choice but to agree to the eldest princess to frame Fan Xian at the night banquet. The eldest princess's defense of Fan Xian at the night banquet actually added fuel to Zhuang Mohan's troubles.What shocked Fan Xian even more was that Yan Bingyun was arrested in Northern Qi because he leaked secrets for the eldest princess.
