The story begins with a strange commission.
Wu Xie, a small owner of an antique shop, received a mysterious female customer-Qiu Yingying on a rainy night. She is not an ordinary person, but a researcher who specializes in the history of ancient science and technology and cryptography. She has a capable temperament and a look of vicissitudes in her eyes that belies her appearance. Instead of antiques for sale, she brought a broken bronze mirror of a yin-yang fish.
The fragment of the mirror is the only relic left by Qiu Yingying's grandfather, an archaeologist who disappeared in the Kunlun Mountains forty years ago. Strangely, every night when the moon is full, if these fragments are immersed in rootless water at a specific angle, the water will no longer reflect the reflection of the moon, but will emerge an ever-changing star map, the trajectory of which completely violates the known astronomical laws.
Qiu Yingying told Wu Xie that this star map most likely points to a civilization that has never been recorded in history or mythology - the "Nine Tribes of Guixu". Legend has it that they master a technology called "Tiangong Core", which can compile and reconstruct the "state of existence" of objects and living bodies, almost miraculous. The ultimate creation they left behind, the "Qianqiu Mirror", is said to be a prehistoric supercomputer, which was buried in nine underground palaces named after stars. Once the nine mirrors are integrated into one, the "Tiangong Core" can be activated and even rewrite reality.
Qiu Yingying is looking for Wu Xie not because of his title as "Little Third Master", but because of a notebook called "Ting Lei Lu" passed down by the Wu family's ancestors. This notebook records a long-lost technique of "Tinglei Dingxue", which can decipher the structure of the underground palace by sensing extremely low-frequency vibrations in the earth's veins. The underground palace of "Guixu Jiubu" is built on the "resonance point" of the earth's plates.
