The ancient female general Shen Zhaoning and the modern female lawyer Gu Huaijin both passed through each other's bodies because of their ancestral jade pendants. Gu Huaijin (ancient line) used evidence thinking to clear the Shen family's unjust case of collaborating with the enemy, teamed up with the third prince Xiao Yan to overthrow the King of Yan, established a police investigation department, and fell in love with Xiao Yan. Shen Zhaoning (Modern Line) used his military intuition to solve workplace assassinations, and teamed up with lawyer Jiang Yuzhou to uncover the real murderer Fang Min and the mastermind behind the scenes. He became the chief strategist of the law firm and fell in love with Jiang Yuzhou.
The two lines cooperated across time and space through the jade pendant synesthesia - Gu Huaijin taught Shen Zhaoning the art of war, and Shen Zhaoning taught Gu Huaijin legal logic. King Yan's secret overseas leads to the White Lotus Sect, Gu Huaijin goes overseas to uncover the truth about the "Twin Lock"; the high-ranking official behind the Fang Min case in the modern line has been sacked, and the transnational consortium has been destroyed.
The jade pendant shattered and the countdown ended. Both of them chose to stay in the post-travel world - Gu Huaijin became the queen and minister of Dali Temple, protecting the legal system; Shen Zhaoning bid farewell to Gu Huaijin's identity under his real name and continued his career and love. The dual time and space are mirror images of each other, living each other's best lives.
