When Li Shisan from Qingshi Town was seventeen years old, he spent three years of his life in exchange for a strange stone engraved with lotus flowers. When he discovered that there was a Nine-Aperture Crystal in his heart, the threads of fate had quietly woven the mirror world of the Three Lives - the white fox he saved in childhood turned into a wife, the ice coffin opened by the young man sealed the future Taoist monk, and the bloody young man who fell from the sky during the middle-aged tribulation actually called him his grandfather.
The fragments of the ancient bronze book are scattered across the eight universes, and the tide of chaos is about to swallow up the nine planes. Li Shisan's left hand holds his grandson who has returned from reversing time and space. On his right shoulder stands his first love who walked out of the star map. Behind him are nine daughters of destiny who gathered from different timelines. The love marks between their eyebrows are the final key to completing the ancient book.
When the sweet-scented osmanthus in the Mirror Flower Realm covers the Changli Sword, and when the blood sea in the Mirror Moon Realm pours into the galaxy, people see the white-haired sword immortal holding the newborn baby in his arms and crushing the void. This is the end of the fateful reincarnation and the starting point of the closed loop of time and space - it turns out that the shocking glimpse by the Luoshui River fifty years ago was the cause and effect planted by the grandson's daughter-in-law traveling through time and space three hundred years later.
