Later that year, the conspirators tried again. Their plan was for Princess Eyi to invite Huo to a feast, and then to ambush Huo and kill him, and then depose Emperor Zhao and make Prince Dan emperor. (However, the Shangguans allegedly conspired to instead to have Prince Dan killed once he arrived in the capital, and for Shangguan Jie to declare himself emperor.) The conspiracy was revealed by a servant of Princess Eyi, and the conspirators were arrested and executed with their entire clans. Princess Eyi and Prince Dan committed suicide. Empress Shangguan was spared, however, because of her young age and her status as Huo's granddaughter.
