In the vast mountain forest filled with miasma, Liu Yanzhi, an orphan Orion girl who is familiar with "Herbal Medicine for Famine Rescue", rescues Su Yanzhi, a lost son of a wealthy family. The "Book of Mountains and Seas" in his hand is full of errors and omissions, but her unique "Mountain and Forest Classics" - smelling scents, identifying poisons, and gaining insight into the ecology - have become the basis for the two of them to overcome dangers together. From seeing through the murderous intention of the white poisonous umbrella to the wise resistance of the drug dealer Du Heng's greedy hunting of rare animals, Yan Zhi sublimated the survival wisdom of the hunters into the "ecological chain balance" of protecting the mountains and forests. Rejecting the drama of robbery, she joined forces with the old hunter Shi Pan, the medicine-gathering girl Ah Yin and other mountain people to establish the "Mountain Forest Protection Association", turning the hunting bow into a monitoring eye. This is a sweet love that grows in the fragrance of pine needles and the cries of animals and birds. It is also a legend of mountain forest guardianship composed by the daughter of Orion, with natural history as the string and ecological protection as the score.
