As a bald graduate student majoring in folklore, Wen Ning's graduation thesis was titled "Test of the Forbidden Moon in the Mid-Autumn Festival - Tracing the Origin of an Endangered Folklore." After reading the proposal report, the instructor adjusted his glasses and pondered for a long time: "This... Topic selection is a bit dangerous, how about changing it to another one?" Wen Ning smiled confidently: Thank you for the invitation, outstanding young people in the 21st century do not believe in strange powers and chaos. In order to collect first-hand information, she went to Tsukimi Village, the birthplace of the legend. A village that still strictly abides by the ancient taboo "No moon viewing during the Mid-Autumn Festival". The old people in the village avoided her like a snake or a scorpion, and the eyes of young people her age were full of fear. "The moon will see." "If you are spotted by 'Gui Ying', you will never come back." Wen Ning just thought it was a foolish talk about closing the village. Until the night of the Mid-Autumn Festival, her traveling companion and best friend who had no taboos stayed under the moon for ten more minutes. Then, it was like the best friend evaporated from the world, surveillance, footprints, smell... All traces of existence were wiped clean. Only a crumpled note was left, with the panicked handwriting of my best friend on it: [They are recruiting. Recruitment? What recruitment? Is Guanghan Company in the Moon Palace doing some autumn recruitment? ! The ancient legend is no longer empty talk on paper. Under the cold moonlight, the indescribable "osmanthus shadow" begins to spread. Wen Ning's worldview was shattered. In order to find her best friend, she must take the initiative to step into that weird world that only people who stare at the moon for too long would enter. This time, she wanted to verify her thesis herself. Conclusion: Tutor, you are right, this topic cannot be written by humans! Help!
