A gentle breeze suddenly rose, and several sheets of paper fluttered down to Ran Yan's feet. She bent down, picked up two of them, and glanced over them. Indeed, just as she expected, they were all about how Dou Chengfeng and others harmed Chai Xuanyi and how they intended to take liberties with Princess Wenxi.
Ran Yan had tossed and turned, unable to sleep last night, thinking over the entire case thoroughly.
There was a significant flaw in the case: Li Wanping knew that the murder was committed by Chai Xuanyi, so she took the blame herself and committed suicide to save his life. Then, as a person with only a day's memory, how could Chai Xuanyi know about his hatred for Dou Chengfeng and the others?
There were two possibilities: one was that he had a habit of keeping records, and after losing his memory, he inadvertently saw what he had written before, thus reigniting his hatred. The second was that someone had reminded him and incited him to seek revenge.
