At the end of the Northern and Southern Dynasties, during the Taijian period of the Southern Chen Dynasty, there was a secret saying in Jiankang City that "the Xie family has a daughter who can wear a spring shirt". The reference is not to beauty, but to Xie Wanyi, the legitimate daughter of the Xie family, who is good at solving puzzles and reading people's hearts. She was born into a declining noble family, and with her keen eyes and ink-making skills, she weaved a dark web between aristocratic and poor families.
In the spring of March, the Northern Zhou Dynasty envoy came to visit, and the deputy envoy Xiao Jin took charge of the important position of Honglu Temple with his humble background. At the palace banquet, a party of "Jin Ye Chun Han Mo" triggered an old case - this was the imperial ink recipe that was lost when the Xie family was falsely accused of collaborating with the enemy twelve years ago. Xie Wanyi was ordered to approach Xiao Jin to investigate, but found that this powerful official known for his coldness was actually a mute boy she had rescued at the border when she was young.
