When reading the "novel" of her friend A Yuan, Yue Xi had already been kept up all night by the regrets of "Slaying the God", secretly vowing to rewrite the plot - until she peeled the warm white egg handed to her by Lin Qiye, a strong light suddenly appeared, and she actually entered this tragic world!
She didn't know that this "novel" was a book of destiny that controlled cause and effect, that A Yuan hid the secret of subversion, and that she was the reincarnation of Chang'e whose soul was damaged and was recuperating in another world. This return was fate. "I'll protect you from now on!" The promise she made while peeling her eggs became a life-and-death agreement during the Ghost Faced King's raid. She fought back to back to death with Lin Qiye, who had awakened to the Divine Void.
From then on, the funny and warm Yuexi became the light of everyone: Lin Qiye always protected her, Wang Mian took off his cold disguise and guarded with action, Zhou Ping, who was afraid of society, broke through the barriers to hold the sword for her, and the cold goddess cherished each other.
But the book of destiny has been tampered with, a conspiracy to damage the soul has emerged, and the world is in danger. Yue Xi uses comedy as her armor and redemption as her obsession. She puts herself in danger time and time again, and finally goes into desperate situations to protect all sentient beings.
Later, some people murmured promises under the moonlight, some stood withered on the rooftop of the mental hospital, and some endured grief in the training room and repeated the breathing method she taught - they never doubted their cherishment of her, but in the end they could not keep that beam of light. And A Yuan's true identity hides the most painful truth.
