Flying in the Dark

On the night of moving, 23-year-old Xu He died in a room he had half-packed. Her landlord was the first to come in and took away a pair of reading glasses that had been missing for three days from the table. Her ex-boyfriend owed her $5,800 and threatened her with her night job. Her next-door neighbor helped her pay the rent, went to see a doctor with her, and only asked one thing after her death: whether she was still breathing in the end. Twenty minutes. Twenty minutes that no one saw. A textbook that she had clearly said she would use "next month" appeared in a book box with another person's name on it, stained with blood. Logic teacher Zhao Yinan reasoned one by one in the same way he taught his students, and then found that the conclusion he wrote down had committed the fallacy he had mentioned on the blackboard. Detective Shao Ning said: First I ask you what you saw, then I ask you what you heard, and finally I ask you what you thought. Everything Xu He did - taking screenshots, taking photos, and keeping accounts - was adding a person who saw it to "no one saw it". None of those things killed Xu He. They're just always there.
