In the third year of Tianqi's reign in the Great Zhou Dynasty, Crown Princess Chu Qingli was deposed due to the "scourge of witchcraft" and was imprisoned in the cold palace. When she touched the "bleeding" ancient bronze mirror, what appeared in the mirror was not her own reflection, but a woman in white who claimed to be "the last Yaochi Immortal Envoy".
"The spiritual veins are about to dry up, the catastrophe is coming, and the power of this human dynasty has been exhausted." The prophecy of the immortal envoy and the spiritual fire ignited at Chu Qingli's fingertips simultaneously burned her knowledge. What was even more frightening was that she saw in the mirror the future three months later - the imperial city was reduced to scorched earth, and the newly-consecrated crown prince's concubine stood among the mountains of corpses and the sea of blood, with a strange lotus mark blooming on her forehead.
In order to find out the truth, Chu Qingli embarked on a dual journey. On the surface, she was a down-and-out noblewoman who regained the favor of the emperor through her embroidery skills; secretly, she practiced the "Yao Chi Heart Sutra", searched for ancient records in the library of the Imperial Prefect's Mansion, traded spiritual materials with mysterious medicine dealers, and even secretly cultivated a group of children from poor families who could sense spiritual energy.
When the Crown Prince's concubine's "Red Lotus Fire" burned down half of the imperial city, Chu Qingli finally understood that behind this spiritual disaster lay the thousand-year grudge between the world of immortality and the dynasty. And she, the "outsider" who accidentally obtained the fate of immortality, will become the key piece to break the deadlock.
But the chess pieces were never her end. When the national master Mo Linyuan handed the natal sword to her hand, this man who once said "immortal cultivators should not interfere in the mortal world" would not have thought that one day, his sword would open the gate of heaven for this woman, and she would redefine the world of immortals and mortals in this world.
