Patinated Bronze Key

A frightening call came in on a rainy night. Archaeologist Li Jing disappeared mysteriously, leaving only a string of mysterious numbers, a set of strange coordinates and a ninety-day countdown. One hundred and eighty-seven days later, a late package crossed the mountains and seas, and energy engineer Su Shunyu was involved in a shocking mystery that spanned two thousand years. The bronze key in the package is rusty, but it conceals modern industrial-grade precision patterns - the eighth extra star point on the handle of the Big Dipper, and the cylindrical key teeth with constant spiral groove lead, all tell the secret behind the "antique" status. The gears of the bronze waterfowl from the Warring States Period perfectly match the modern gyroscope. The mercury rivers in the Lishan Underground Palace are actually multiple barriers. The hollow structure of the Han Dynasty mourning platform is actually an infrasonic listening station. The seemingly unrelated ancient relics are connected in series to form a mysterious system that has been running for thousands of years. It is said that the jade seal of the country is not jade, but the energy core buried deep underground; the bronze key is not a lock, but a physical interface to activate the system. When the "Oracle of Destiny" is revealed to be a scam controlled by infrasonic waves, and "Get the Jade Seal to Win the World" is actually the ultimate code for geological stability, Su Shunyu is forced to transform into a "fictional bait" and use novels as a blade to test the truth. While dealing with the mysterious organization that covets the key, she decodes the cross-border clues left by Li Jing. Archaeological discoveries collide with hard-core engineering, and historical myths are intertwined with science fiction settings. She holds the only key and stands at the crossroads of fate: Should she destroy the key to preserve the present, or risk activating the system to explore the ultimate truth? When an engineering agreement two thousand years ago meets the choices of modern humans, when the key is turned, is it the dawn of civilization or the abyss of uncertainty that awakens?
