On that night, Li Quan slept in the bedroom. Since 9 o'clock, Sun Zheng and Chen Fang took drugs in the living room again. After taking a large amount of drugs, Chen Fang was extremely excited. She had a relationship with Sun Zheng, but unable to suppress the excitement brought by drugs, she went to the bedroom and had a relationship with Li Quan. Until the wee hours of the morning, Chen Fang was still very excited, constantly teasing Sun Zheng.
