In 2157 AD, quantum physicist Ling Ye accidentally fell into the Dachen Dynasty in another world along with the core of the cutting-edge equipment "Xingcha". At the same time, Chu Qingli, a modern female college student, touched the mysterious bronze mirror and "traced the moon", and her soul was transformed into the concubine of the Shangshu Mansion. The two possess future technology and modern thinking, and are regarded as "alien", causing turmoil between the government and the public.
The national master Xuan Jie has a glimpse of the secret of heaven and wants to control the power of time and space; Prince Jing Xiao Jingrui is ambitious and attempts to seize technology for power; the Beirong barbarians are eyeing the opportunity to go south; even the seemingly gentle seventh prince Xiao Jingheng quietly intervenes. What's even more fatal is that the existence of the two people is causing the laws of time and space to collapse. Light and shadow frequently overlap in the imperial capital. Chu Qingli is even facing the crisis of "time and space assimilation" and the dissipation of body and soul.
Ling Ye and Chu Qingli struggled to survive in the cracks of various forces, from being suspicious of each other to joining hands and relying on each other. They went deep into the thousand-year-old ruins "Xuanji" and discovered that "Xingcha" and "Suyue" were actually the time and space anchors and stabilizers left by ancient civilizations, and their journey through time was not accidental.
In the end, Beirong defeated the city, and the disintegration of time and space was imminent. Ling Ye resolutely used his body as a shield, and Chu Qingli gave up his soul to accompany him, and launched a shocking ceremony in the forbidden area of the palace to guide the torrent of laws in the two worlds. They built a "heart wall" with a will that transcended time and space and reversed the disaster. The price was that their memories were dusty and the past was covered up.
At the dawn of the new era, Ling Ye, who had lost his memory, became the minister of the Ministry of Industry, Chu Qingli opened a new school, and ancient civilization quietly absorbed the afterglow of the future. However, deep in the starry sky, the surveillance eyes of the unknown civilization still flicker coldly. Is this catastrophe that spans time and space really the end, or is it the beginning of another bigger chess game?
