Mu Yunji, Emperor Zhaowu of the Dayan Dynasty, once saved the dynasty from collapse with his iron and blood tactics. However, during the winter solstice to worship the heaven, he fell into the rift of time and space when the altar collapsed. When he opened his eyes again, Xuan Mian was stained with dust. He was in the bizarre modern streets and became a helpless "alien".
Yun Muxi, an antiquities restorer, isolates herself from the world with a cold attitude, and only talks to thousand-year-old antiquities with her fingertips. However, she unexpectedly picks up this "weirdo" wearing a royal robe and with blank eyes. When they first met, he thought she was indifferent and rude, and she hated him for being stubborn and old-fashioned; but when the emperor put down his dignity and learned to use a mobile phone, when the cold beauty made an exception to explain modern rules to him, the two hearts that were separated by overlapping time and space quietly came closer in collisions. An encounter that spanned a thousand years changed the fate of the two people.
