When cultural relic restorer Su Nianci accidentally dies while restoring a mysterious bronze, history researcher Shen Shigui's world completely collapses.
Three years of love was gone in an instant.
While sorting out her belongings, Shen Shigui discovered a shocking secret - Su Nianci had been studying the legend of the "Guardian of Time" during his lifetime. Ancient books record that the soul of the deceased will be divided into seven pieces and scattered in the long river of history. As long as these seven soul fragments are collected, she can be resurrected.
"If I could turn back time, I would pay any price."
With this obsession, Shen Shigui embarked on a journey through seven historical eras.
During the Spring and Autumn Period, he met Chen Cai, the master and disciple of Confucius, and also met Lin Wanyin, who possessed a fragment of Su Nianci's wisdom. Her words "Remember me, but don't stop for me" made him experience heartbreak across time and space for the first time.
During the Warring States Period, during the bloody revolution of Shang Yang, the idealist Xiao Ruohua sacrificed her life for the ideal of the rule of law. The fragments of tenacity in her body made him understand what true faith is.
During the Qin and Han Dynasties, the first emperor's daughter Ying Qingya died heroically to protect the classics; Zhang Qian's wife Zhang Waner waited ten years for her loyalty, and every encounter was a baptism of the soul.
The talented girl Xie Lingyun of the Wei and Jin Dynasties, the court musician Li Qinglian of the Tang Dynasty, the doctor Shen Huixin of the Song Dynasty, Zheng Zhiruo of the Ming Dynasty... Seven eras, seven women, each of them has the shadow of Su Nianci, and every parting is a growth.
But when he finally gathered the seven soul fragments and prepared to resurrect Su Nianci, he discovered a bigger truth...
