Zhai Yao's mother-in-law and her family were bitten by a rare round-spotted viper while camping. Only her husband Jiang Ji's biological company had the antidote serum. When Zhai Yao asked for urgent help, Jiang Zong was accompanying Bai Yueguang to celebrate Sun Xiao's birthday. Not only did he not listen to the explanation, he mistakenly thought that the ones who were bitten were Zhai Yao's parents. He mocked them and blackmailed them for extorting money. He also gave Sun Xiao a life-saving serum and even pretended to receive Zhai Yao's valuable birthday gifts and gave them to Sun Xiao. In the end, five members of her husband's family died due to lack of timely rescue. Zhai Yao's investigation found that Sun Xiao's parents deliberately released the poisonous snake, and Sun Xiao also deleted Zhai Yao's message asking for help. Jiang Zong collapsed and regretted after learning the truth.
