Lin Yu, a modern ordinary employee, was caught in a strange purple light door on his way home from overtime work. When he woke up, he was in a fantasy world with towering vegetation and full of unknown creatures. What caught him even more off guard was that lying next to him was a little girl with light blue curly hair, Xingya. The girl called him "Dad" in a daze, and inexplicably, there was a vague instruction in his mind that "you must protect Xingya and find a way home."
This world is full of dangers: giant mushrooms that can devour living things, strange birds that can control wind blades, and mysterious shadows that seem to be pursuing Xingya. Lin Yu has no experience in surviving in a fantasy world, but he has to grow up quickly for Xingya. He uses modern knowledge combined with the "natural perception" ability acquired by chance to find hope in the crisis. While he was learning to build a safe temporary shelter and identify edible fantasy plants, he was also exploring the mystery of Xingya's life experience and the truth about his own time travel. As the adventure deepens, he discovers that Xing Ya hides secrets related to the balance of the world, and the goals of those who pursue them are far more dangerous than he imagined. A fantasy adventure with guardianship as its core begins here.
