Snowy Night, or the Seventh Murder of Poetry

"Snowy Night, or the Seventh Murder of Poetry" Poetry is the murder weapon, and readers are accomplices. On a snowy night in Old Beijing, the great poet Shen Hengtang was frozen to death on the ice of a lotus pond, with a line of poetry that no one should have read branded beside him. Poet detective Li Xueqiao was ordered to investigate, but found that all the evidence pointed to himself - the code on the deceased's hand pointed to the reader, the stolen poem manuscript became the prelude to the murder, and his name and photo were printed on a book of the Dead Poets Society called "Ice Tongue". What's even more frightening is that official records show that Li Xueqiao himself died a year ago. When his name appeared on the poem manuscript under the ice, and when the "shadow" with the same appearance walked on the snowy night, Li Xueqiao realized that this was not a murder about poetry, but a massacre with poetry. **In this puzzle where words are the murder weapon, everyone who reads this poem has already participated in the crime. ** And when you open this book, you have become the next reader.
