A drug used by Zhang Shufen and Gu Hongmei to drug Song Wanyue. The system carefully measured the dosage—Gu Dahai got a lighter dose, Zhou Shanshan a heavier one. The plan was to drug Song Wanyue so Gu Dahai would lose control and have intimacy with her, but the plan backfired when Zhou Shanshan and Zhang Shufen were drugged instead.
