Ling tide, the former "Zhen Yesi" cultivator, was deprived of half of his life span for breaking into the royal secret treasury, leaving only three months to burn lanterns. When she was seriously injured and comatose six years ago, she had a night of entanglement with a mysterious man. When she woke up, she gave birth to twins "Chenchen" and "Yueyue" - the boy can see the lights of Shouyuan, and the girl can understand the voices of objects. In order to survive and find a father for her child, Lingxi sneaks into Chang'an with her child, but unexpectedly discovers that the birthmark on the child's wrist exactly matches the dragon talisman of the rumored "dead" former prince Zhaoye.
She was forced to disguise herself as a married palace maid and sneak into the palace. She used "talisman paper as a band-aid" and "immortal magic to coax the baby to sleep" to cope with the house fight, while relying on Chenchen's "lantern viewing technique" to find out the mole who stole longevity. Little did they know that Zhaoye's fake death was actually a plan, and he was secretly investigating the royal family's conspiracy to use the "furnace" to refine longevity. When Lingxi's life-extending talisman was accidentally attached to Zhaoye, the dusty past of the two was revealed together with Chang'an's shocking secret.
