Under the moonlight in Chang'an during the prosperous Tang Dynasty, the sick and talented Shen Yao was forced to marry the general Li Yifeng. However, on their wedding night, she broke up her husband's affair with her cousin Su Wan. After drinking a glass of poisonous wine, she died. Only then did she realize that this wrong marriage was actually a love disaster set by heaven for the tenth life - she was originally the spirit of the mirror of the moon in the Yaochi, and he was the fallen immortal Yinghuo Xingjun. The prophecy of blood and tears was carved on the stone of three lives. When a rift in the demon world tore open in the night sky of Chang'an, the Heavenly Emperor's mount with a glass heart climbed out of the bronze coffin. The former gentle cousin shed her human skin, revealing the true appearance of the Moon Soul Mirror Spirit. It turned out to be the half-wisp of evil soul that Shen Yao had separated to survive the love tribulation. She stole not only her marriage, but also the god-killing poison that overturned the three realms. With the blood moon in the sky, Li Yifeng used his back as a shield to bear the nine-layered thunder punishment for her. Shen Yao crushed the ice crystal hairpin to awaken the memory of the tenth life: he was the priest who cut out her heart in the Shang Dynasty, the general who shot arrows from the tower in the Warring States period, and the idiot who fed her poison for twelve years in this life. When Liuli's heart was reunited in the Demon Lord's claws, the candlelight of thousands of families in Chang'an City turned into the Milky Way. They stepped on the fragments of the Three Life Stones and kissed. Ren Tiandao was broken in the fire of love. With a blood moon wedding ceremony that shocked the three worlds, the fate of "falling in love with Chang'an Moon" was tempered into a thousand-year-old love lamp.
