I recommend a few novels about willow trees to you, including "Wilderness: Starting from the Willow Tree","Starting from the Willow Tree to Crazy Evolution","I Became a Willow Tree","The Space Willow of the Revival of Reiki", and so on. These novels all involved the unique abilities and growth of the willow tree. Some even incorporated elements such as immortal cultivation, mythology, science fiction, and so on. I believe you will like them. I hope my recommendation can meet your needs, Muah~
