Hainan Treasure Island is connected by mountains and seas, with extremely diverse biological species and beautiful scenery, just like the back garden created by Nuwa. There are nearly 200 species of rare and endangered plants here, and even plants that are extinct elsewhere can be seen in this tropical primeval forest. Lin Mu is a top student in botany at a top university in the country. A series of changes made him, a social fear, take the initiative to return to his hometown and become a forest ranger. Along the desolate and rugged paths, he visits every plant and listens to every animal. He repeats the daily routine of his father and protects the plants that his father once defended with his life. The sudden appearance of Ci Yingxue and botanist Wen Heng gave him a deeper understanding of the plant friends around him, and he gradually got out of his self-imprisonment and relaxed his heart. In the process of protecting endangered plants and rescuing stolen plants with the two, Lin Mu resumed the study of plants, played a foundational role in the protection of endangered plants in tropical primeval forests, and became a senior botanist.
