The night I transformed into the devil's concubine in the 999th room, I ran away overnight and fell into the mortal world. I originally wanted to be a salted fish in the lower realm where spiritual energy is thin, but I didn't know that mortals in this world are still making fire by drilling wood and tying ropes to remember things. Seeing that winter was approaching, I casually drew a fire array to keep warm, and was actually regarded as a god by the natives. When the demon king followed the spiritual energy fluctuations and came to me, I was leading the believers to build water conservancy, build roads and build cities. He pinched my cold-red fingertips and chuckled: "Is my runaway concubine a betrothal gift for myself in the lower realm?"
