Urban white-collar Lila Wood faints from overwhelming work pressure, quits her job and returns to her hometown to take over the barren Mystery Grove Forest left by her grandfather. She accidentally awakens the Fantasy Forest System, gaining the ability to communicate with animals. Rare animals including golden monkeys, cloud leopard mother and cubs, rhinos, Asian Elephants, pythons and other rare animals come to the forest one after another. Lila gradually lets go of her resistance and forms deep bonds with the creatures. She deals with external disturbances, the arrival of forestry inspection and scientific research personnel, and discovers that the forest hides a Forest Heart that can nurture the intelligence of living beings. If the host leaves, the animals will regress, so Lila decides to stay permanently to guard this mountain forest home.
