If there were camera and lighting here, a huge close-up should probably be given to Wei Cang in the darkness.
Wei Cang, niece? Wei Lingling, a family very close to the Xiao family. Wei Lingling was more likely than Wei Cang to enter the Wei family. In fact, Xiao Shuai was really good to Wei Lingling, probably because the latter was young and romantic, fitting the role of any well-behaved daughter; while Xiao Shuai's truly beloved daughter, due to her family upbringing, was incredibly calm and never willing to act coquettishly, which inevitably caused some regret and helplessness for Xiao Shuai.
So it was Wei Lingling who carried the poison that caused the Xiao family to be poisoned.
However, even with such a family feud, Xiao Tingyun spoke and looked at Wei Cang in a way that reminded people every minute of a widely circulated but not-so-daring-to-gossip about a matter in Beiping - it was said that Xiao Tingyun and Wei Cang once had an affair.
