Lu Yanqiu, a Northern Song dynasty mounting and framing craftsman, accidentally activates his family's heirloom jade pendant. When he opens his eyes, he finds himself in Chang'an's West Market, where foreign merchants crowd the streets.
A strange curtain of water above Bianjing's Rainbow Bridge livestreams his encounter with Pei Jiulang, a musician from Pingkang Ward. The man looks exactly like him and wears a fragment of jade at his waist that can trigger distortions in time and space.
As a Persian scimitar slashes through a foreign dancer's sleeves, on-screen comments from the Song dynasty burst across the sky above the prosperous Tang:
"Run! The Sasanian merchant behind you has drawn his blade!"
"The filter's turned blue-green! This is Yan Liben's style!"
On one side are constantly refreshing tips in copper coins; on the other, a deadly pursuit spanning three centuries.
Lu Yanqiu gradually discovers that this transmigration livestream was recorded in an astrological scroll from the era of Wu Zetian long ago. And the burden carried by Pei Jiulang turns out to be the bloodiest imperial clan mystery of the Xuanzong era...
