Who Controls the Ups and Downs of the Prosperous Tang Dynasty?

In the first year of civilization, Emperor Gaozong died, and it was revealed that the deposed prince Li Xian was plotting a rebellion. Wu Zetian ordered Zuo Jinwu Guard General Qiu Shenji to go to Bazhou to search the residence of Li Xian, a commoner, and search for evidence. Li Xian's eldest son, Li Guangshun, was killed by a missing cane, and his body's whereabouts were unknown. Li Xian, who was imprisoned in another room, was also forced to kill by Qiu Shenji. The case of Li Xian's rebellion ended here. In the first year of Yanzai, Wu Zetian received a secret report and ordered to detain Fang Shun, the general of Zuoying Yangwei Zhonglang. Three more years later, another major case occurred in Shendu, and the finger pointed at Li Xian's case again. Is this a coincidence or someone did it on purpose.
