The Sky Screen Between Two Worlds: A High Schooler's Cross-Time Daily Life

High school student Cheng Qianyue returns to the modern era after spending ten years trapped in the Great Feng Dynasty, but unexpectedly leaves behind a livestream System connecting the two eras. As she settles back into high school life, tries to catch up with the academic demands of H Province, and enjoys the everyday pleasures of milk tea and shopping malls, the sky screen above the Great Feng Dynasty never goes dark. The splendor of Chinese civilization unfolds before the people of Great Feng through the screen.

They see skyscrapers piercing the clouds, more imposing than the palace halls; iron birds (airplanes) soaring across the sky and long dragons (high-speed trains) racing over the land, far faster than a thousand-mile horse. Even more astonishing is the miracle of “divine seeds” yielding ten thousand jin per mu, prompting people who once feared famine to exclaim, “These must be the methods of immortals!” Even the lights that never go out, day or night, amaze the people of Great Feng, accustomed to the faint glow of candles: “It's as if daylight has come!”

Scholars and poets no longer ask only about lines of poetry. Instead, they investigate how the “tall buildings” were built. Agricultural officials gather around the sky screen to record what the “divine seeds” look like, hoping to solve Great Feng's grain shortage. Craftsmen pore over diagrams of high-speed train wheels and tracks all night, hoping to build a “vehicle that needs no horse.” Cheng Qianyue has no idea that what she left behind was more than a livestream System. It was also a key to a new world. Through the sky screen, China's modern civilization is quietly reshaping the Great Feng Dynasty's understanding of the world, binding the fates of two eras together through the collision and blending of civilizations.
