Sang Luo, who grew up in the Flower God Tomb, was born without emotion and would only make everything bloom. The moon tree in the Nine Heavens withered, and the roots of love in the three realms were about to be cut off. She was sent to the heaven to cultivate the tree, but accidentally fell into the cold pool under the moon, awakening the fallen angel Xuan Heng, who had been sealed for three hundred years. One is a flower used by the gods to replenish their destiny, and the other is the sin god under the moon whose name has been erased by the heaven. Sang Luo and Xuan Heng formed a common curse, from testing each other to protecting each other in life and death, they also gradually revealed the truth about the death of the moon tree, the flower god's sacrifice, Shen Yuan's old ministry and his own old destiny. She thought she had no soul and could not love. Later I learned that lovelessness was not born, but someone had personally removed the love from her in order to let her live.
