The Yunsheng Dynasty guarded the destiny of the country with the "Sacred Tree of Supporting Light". Everyone in the capital respected the tree, but no one knew that under the roots of the sacred tree was the "Moon Eclipse Abyss" that could swallow people. Royal families of all dynasties secretly used women with elven blood to feed the tree to prolong its life. Su Qingtang, a modern botany blogger and wilderness survival expert, takes the form of Ning Zhixia, the abandoned daughter of the Hou family. She is sent to celebrate Prince Jing Xiao Zhi at the beginning of the story, who is under a tree curse. She was accidentally bound to the "Ten Thousand Trees Illustrated Book", which allows her to hear the voices of plants, read the remaining memories of plants, and unlock all-round elven skills such as refining medicine, controlling vines, setting up formations, and forging weapons. As the half-elf blood in her body awakens, the palace secrets, old debts of the dynasty, and the truth behind the disappearance of the elves are revealed. Step by step, she discovers that the so-called sacred tree has never been a refuge, but a scam that has been carefully maintained for hundreds of years.
