Watching Videos at Home, I Find They Connect to the Past and Present

In a modern city, Zhou Wanwan is a history major who has just graduated. A typical history fanfic enthusiast, she is obsessed with creating historical fanfiction, but too lazy to socialize or take action. After graduating, she simply stays home and becomes a shut-in. Her biggest dream is to become a million-follower history blogger, and her daily life consists of editing historical video compilations and staying up late watching all kinds of history-related short videos. One night, while watching videos late, a mysterious pop-up suddenly appears on her phone, binding her to a space-time connection System that calls itself Xiaotuantuan. Zhou Wanwan assumes it is junk software, casually taps confirm, and goes right back to her homebody routine, completely unaware that the videos she edits and the content she watches have already been projected silently across the skies of several ancient dynasties, becoming messages from beyond the heavens in the eyes of the ancients.
