Later in 746, yet another incident again nearly brought disaster to Li Heng. One of Li Heng's other consorts, Consort Du, was a daughter of the official Du Youlin (). Consort Du's brother-in-law Liu Ji () had a dispute with the Du family and falsely accused them of using witchcraft in favor of Li Heng. Li Linfu had Ji Wen interrogate Liu, and Ji implicated Liu in the alleged plot as well. Du Youlin, Liu, and Liu's friend Wang Zeng () were all caned to death, and Li Heng felt compelled to expel Consort Du from the household as well. Li Linfu also used this case to have two other officials friendly with Liu, Li Yong () and Pei Dunfu (), executed by caning.
