No, the assassination in Meilin of "Long Xiang Si" was arranged by Mu Fei, who, in order to avenge the deaths of his clan members at the hands of Chi-Chen, set up an extermination array to abuse Xiao Yao.
"Long Xiang Si" Xiao Yao was abused in Mei Lin because she was the daughter of Chi-Chen, who had massacred many clans in the Central Plains, and Mu Fei planned the Mei Lin assassination in order to avenge the deaths of his relatives. Mu Fei took all the hatred towards Chi-Chen and retaliated on Xiao Yao, but Xiao Yao was in denial, in Xiao Yao's point of view, she had never seen Chi-Chen, and even her mother's life was cut short in Chi-Chen's hands, and everyone called Chi-Chen a murderous devil.
Small Yao can't accept that Chi-Chen is her own father anymore, not to mention that she has never enjoyed half of Chi-Chen's shelter. Even though Xiao Yao's body was severely tortured by Mu Fei, she still repeatedly emphasized that "I have no relationship with Chi-Chen, my father is King Hao Ling". Until Xiao Yao was dying, she still said to Mu Fei: "You killed the wrong person".
The reason why XinYue wanted to kill XiaoYao
Since ChenRong XinYue married to ZiGoldenTop, she never felt the slightest bit of love from the tinkling of gems, once she thought that the tinkling of gems was really like what FengLong said, the sincerity was never placed on a woman, and it was this kind of heartlessness that made XinYue feel relieved in return, she married the tinkling of gems when she thought that she was unique Her confidence did not come from herself, but from the Shennong Clan, the Chishui Clan, and the entire Central Plains behind her.
But then there was Nian, who used the entire empire as a dowry to marry the tinkling of gems, and she had all the confidence that Nian had, even more than she did, but after all, Nian lived in the Five Divine Mountains all year round, and had the name of queen but no real power, so she was naturally no threat to Xinyue.
But later, when she saw the images of Xiaoyao and the tinkling of gems together, Xinyue became more and more afraid day by day. She knew that the tinkling of gems was neither sentimental nor ruthless, but gave all to Xiaoyao alone, plus the fact that the tinkling of gems had been intentionally supporting the other clans, the Shennong clan was becoming less and less important to him, and Xinyue was worried that her own queen's position would not be guaranteed, and so she moved to kill Xiaoyao.
