Huang Lingxi, a female medicine collector, is born with a pulse type and can sense the spiritual veins of the three worlds. Three hundred years ago, Tianyuan's spiritual veins dried up. Demon King Ao Xu used a forbidden technique to inhale an abandoned spiritual vein, but the curse was implanted in the core and is spreading to the three realms through the spiritual vein network.
Only those with natural veins can purify the curse.
As a result, Huang Lingxi was involved in this fate - she took the waste demon Qi Jin deep into the gap of the netherworld to find medicine, and was lured to Tianyuan by Ao Xu to inherit her spiritual vein, but was persuaded by the Human Emperor Lu Lin to stay.
She went through three trials, exposed the truth of the curse, and finally fused her veins to become the Lord of Tianyuan and repaired the spiritual veins of the three realms, at the cost of having less than thirty years left in her lifespan.
Qi Jin shared his life with forbidden magic and stayed with her for the rest of his life.
