Is “Fei Yi was assassinated by Wei defector Guo Xun while heavily intoxicated.” true?

Historical fact. The novel describes Fei Yi being assassinated in autumn at Liubei Pool while heavily intoxicated. Chen Shou's Records of the Three Kingdoms clearly records: 'In the sixteenth year, at the New Year's assembly, Wei defector Guo Xun was present. Yi drank joyfully and became drunk, and was killed by Xun's hand.' The core events are completely consistent.
