The human race and the demon race have been separated and opposed for thousands of years, and the law strictly prohibits intermarriage between humans and demons. He Dai, a medical girl with a special origin, lives in seclusion in Qingxi Town. The owner of the steamed bun shop in the neighboring street speaks in dialect, but in fact he is a patrolman who abides by ancient precepts and specializes in controlling the strange people in the mountains. The two people with contradictory views accompany each other day and night, and the dusty past is swept away. Can they break through racial hatred and wait for the good news in the world?
He Daixing has been practicing medicine with his mother since he was a child. He relied on the jade hairpin to suppress the demonic energy. He always thought that he was just an ordinary mortal and did not know that he had dual origins from the royal family and the demon clan.
The dialect across the street means that he started working as a steamed bun shop owner incognito. His father's generation slayed demons and left endless blood debts. The ancestral Jingxuan ancient blade can identify demons and suppress evil, but it also makes him forever bear the shackles of the fate of "the descendant of demon slaying".
The two got to know each other and secretly fell in love. An old case stirred up a storm, and various forces traced He Daixing's traces. In times of crisis, the jade hairpin shattered, her demon power awakened, and the truth about her life experience that had been buried for many years was finally revealed.
The secret was made public, and the traitors in the court, the Jianghu forces, and the demon clan's main war faction all attacked the two. On one side is the human race's laws, on the other is the demon race's feud. Fang Yanyi insists on protecting He Daixing regardless of the numerous criticisms, and deals with the three forces.
Thousands of years of hatred surged forward, and the two people, burdened by their fate, struggled to find a way for humans and monsters to coexist.
Purpose: Break down racial barriers and exchange peace between the two worlds with gentleness and perseverance.
