In the depths of the netherworld, Meng Po and the Hell Messenger are surrounded by eternal loneliness. They fulfill their destiny day after day, but they still cannot get rid of the shackles in their hearts. Yan Ran, the King of Hell, was sitting in the Senluo Palace, staring at the eternal trajectory of reincarnation in the book of life and death. Seeing the frost and snow in the eyes of the two people, she finally felt compassion.
She shed her crown of hell and transformed into a pretty fairy in a crimson skirt. She walked straight into Yuelao Immortal Palace on the shining river of stars. The red threads in Yuelao Hall are flying like clouds, and the marriage book on the jade scroll is glowing with a warm and moist light. Yan Ran clutched the life soul thread of Po Meng and the messenger from hell, and her eyes flashed with cunning light: "Old man, these two threads have been entangled for thousands of years but cannot intersect. Why don't you show mercy and use the fireworks in the world as a guide to tie a concentric knot?" After saying this, two strands of netherworld energy condensed on the fingertips and gently blended into the red lines, adding a mysterious background to the fate that spans Yin and Yang.
When the spring rain in the mortal world wets the willows of Baqiao, Po Meng transforms into Shen Xueer, the eldest daughter of Prince Yan's palace, with Manzhu Shahua from the Wangchuan River pinned to her temples; the Messenger of Hell takes off his mysterious robe and becomes Gu Yuan, the third prince who was taken hostage in the Northern Desert, with a jade pendant engraved with Netherworld runes on his waist. Yue Lao's fingertips moved slightly, and two red threads passed through the barrier of the three realms and were quietly tied between their wrists. A worldly relationship that spanned the cycle of life and death slowly began with the sound of morning bells and evening drums.
