This is a love story that spans Yin and Yang and runs through the path to immortality.
During the Republic of China, Shen Yanzhi returned to his old house in Huaianli due to his uncle's last wish. While sorting out his belongings, he met Su Wanjing, a female ghost who had been waiting for her lover for ten years. Su Wanjing is stranded in the world due to obsession, and the "Shen Lang" he is waiting for is Shen Yanzhi's grandfather. With the contact, Shen Yanzhi learned about her tragic past - her grandfather was wronged, she ran to save her lover to no avail, and eventually passed away with regret.
One person and one ghost, from the initial fear and temptation, to the gradual growth of feelings. In order to help Su Wanjing resolve his obsession, Shen Yanzhi embarked on the road to redress his grandfather's case, but encountered many obstacles in the process. Su Wanjing secretly helped Su Wanjing with ghost power, and the bond between the two deepened day by day.
After the unjust case was revealed, Su Wanjing could have entered reincarnation, but she remained in the world because she was unwilling to leave Shen Yanzhi. After experiencing the dangers of the netherworld and never returning to the island to realize enlightenment, the two relied on each other's obsession and yang energy to nourish each other, and finally broke away from the shackles of yin and yang, and went on the road to immortality together, creating an unparalleled romance that spanned life and death.
