The story follows a modern female special forces soldier Shen Lei (who was named Han Lei after time travel) who accidentally traveled through the Tang Dynasty and became an orphan of the Shen family, a prominent family in the south of the Yangtze River.
When she woke up, she was caught in the whirlpool of the calculations in the Han Dynasty and the intrigues of the court. In order to protect herself and vindicate her family, she secretly formed the intelligence organization "Jinglei Pavilion" and used modern investigative concepts and fighting skills to gain a foothold in the turbulent Chang'an. From the salt smuggling case on the Longyou Trade Road, to the struggle for the throne between the crown prince and the third prince in Chang'an City, to the secret collusion between the remnants of Webster's party and the Turkic forces, Shen Lei led core members such as Ying 1, Ying 2, and Ying 3 to use secret passages to shuttle through the gaps in power, stirring up all the forces with their ingenuity.
She deciphered the secrets left behind by her biological mother and uncovered the connection between the Shen family's destruction and the deposed crown prince's case...
