Jin Shu was nervous and left on the pretext of preparing tea.Outside the house, three heads were sneaking around, secretly observing the situation inside the house. Seeing Jin Shu taking off her clothes and getting ready to go to bed, Du Ruofei felt nervous and expressed her trust in Xun Changhao.Chang Ren discovered that Jin Shu had put medicine in the tea, and everyone mistakenly thought it was an aphrodisiac. Du Ruofei couldn't hold himself any longer and was pulled by Chang Le and Qi Wan.Xun Changhao actually realized that there was something wrong with the tea, but he still drank it without changing his expression, and lay down on the bed pretending to feel uncomfortable.Seeing Xun Changhao asleep, Jin Shu got up and went to the study to search.Outside the house, Du Ruofei told Qi Wan and Chang Le that Jin Shu was looking for Xun Changhao's investigative diary. She had already dropped the diary at Xun Changhao's signal, but when she lowered her head, she suddenly realized that the diary in her arms was a fake one.
