Li Longji had long known that the imperial court was a place where people were cooked, but he had no choice but to grow up in this family. In order to avoid disaster, he always used hunting to relieve boredom and relieve difficulties. Unexpectedly, during a safari, he encountered a human bully and went to rescue him. He was coaxed by a knowledgeable person to the palace of his grandmother, Emperor Zetian, and was killed. At this time, Li Longji had no way to advance or retreat, so he launched the "Xuanwumen Revolution".
