Qin Fanghao, an ordinary social worker, resigned out of anger when he saw his supervisor embezzling public funds. When he was sorting out his mother's belongings, a rough Pixiu jade pendant with a faint light unexpectedly appeared. From being chased by weirdos in suits, to the mysterious death of the richest man, to the strange shadows in an abandoned textile factory, under the guidance of the jade pendant, she accidentally stumbled into the secret dispute between the Yin and Yang worlds. When Lu Chen, a mysterious man with silver hair and golden eyes, reveals that the jade pendant is one of the "Yin Yang Jue" that opens the door to the underworld, Qin Fanghao is forced to be involved in a century-old conspiracy. Faced with the scorn of the boss and the terrifying trials in the underworld, she held on to the jade pendant with no spiritual roots and resolutely chose to pursue the truth. From the workplace to another world, this life-and-death adventure will eventually reveal the truth behind her mother's murder, and allow her to write her own legend in the gap between yin and yang.
