Chen Yuan, an archaeology graduate student, transmigrates to Chang'an in the Zhenguan era. Penniless, he has only a phone that can connect to all the worlds, so he is forced to make money by livestreaming. He just wants a quiet life, but his first private job comes from the top tipper in his stream, “Heavenly Khan”: investigate the “painted-skin beauty” in Chang'an. On camera, he discovers intricate circuitry beneath the beauty's skin.
Only then does Chen Yuan realize he is not the only transmigrator. An organization called the World-Reforging Society is trying to systematically replace the Tang dynasty's living heart with a “perfect” blueprint from the future. Meanwhile, the Taizong Emperor, who spends lavishly in Chen Yuan's stream and seems to know everything about him, appears to have seen this coming.
From unsolved cases in the ghost market to exam intrigues, from the aftermath of natural disasters to the depths of underground palaces, Chen Yuan is forced to walk through the shadowy side of history. The only things he can rely on are the countless pairs of eyes at the other end of his livestream and the emperor who has placed the whole realm on the gambling table. When viewers from two different eras join forces with a solitary emperor, they must fight a “civilization”-level takeover targeting an entire age.
