In 615, Yuwen was involved in a major massacre of a noble clan. While Yuwen was still Emperor Yang's guard commander when Emperor Yang was crown prince, Li Hun (李渾) the son of the senior noble Li Mu (李穆) the Duke of Shen, who had died in 586, had become angry at his nephew Li Yun (李筠), who had inherited the title of Duke of Shen, and he had Li Yun assassinated, while framing his cousin Li Jutan (李瞿曇) for the murder and had Li Jutan executed. He then bribed Yuwen, his brother-in-law, with a promise that if he were allowed to inherit the ducal title, he would give Yuwen half of the stipend received from the fief. Yuwen persuaded the Crown Prince to in turn persuade Emperor Wen to agree, so Li Hun inherited the title. However, after Li Hun received the title, he only paid the bribe for two years and then stopped. Yuwen, resentful of Li Hun's broken promise, planned his revenge. By 615, there had been rumors throughout Sui territory that the next emperor would be named Li. Emperor Yang therefore particularly became suspicious of Li Hun's nephew Li Min (李敏), the husband of his sister Yang Lihua's daughter Yuwen Eying (宇文娥英, who was also the daughter of Northern Zhou's Emperor Xuan, as the Yang Lihua, the Princess Leping, was Emperor Xuan's wife and empress), because Li Min's nickname was "Hong'er" (洪兒), meaning "son of a flood," and Emperor Wen had long ago dreamed that a flood would overflow the capital. Emperor Yang therefore tried to hint to Li Min that he should commit suicide, but Li Min did not. Yuwen Shu then had the official Pei Renji (裴仁基) falsely accuse Li Hun of plotting treason. Emperor Yang put Yuwen Shu in charge of the investigation, and Yuwen Shu manufactured evidence, particularly persuading Yuwen Eying that Emperor Yang would have the Lis executed anyway, and that she should save herself. Yuwen Eying thus wrote a confession implicating both Li Hun and Li Min. Li Hun, Li Min, and 32 of their clansmen were executed, and their other relatives were exiled. Several months later, Yuwen Eying was also poisoned.
