How did Jiang Rou (Nu Yunrou) die in Jinxiu Weiyang?

In the TV series Unfinished Splendid, in order to frame Li Weiyang, Chi Yunrou deliberately took a small amount of poison, and then said that Li Weiyang poisoned him. Originally, you could detoxify slowly after eating the antidote, but then all kinds of accidents happened, and the poison could not be completely discharged.

When she received the news that her nephew Yun Chi was killed in Yunnan, she knew that Yun Chi's family was doomed and could not stand the stimulation, and finally died.
