After Becoming a Spirit Tree, I Saved Another World

Qi Yu, female, 21, works as a nanny. Then she transmigrated. In another world ruled by demons and beasts, the mortality rate among young ones is so high that there aren't enough young adult demonfolk to fight the magical beasts. As a result, vast swaths of territory have been seized by monsters. Just as Qi Yu was completely lost, the demonfolk discovered her and uprooted her. That's right, Qi Yu transmigrated into a tree, a tree that could cleanse demonic energy and protect demonfolk young from its corruption. It was also the only Purification Tree still alive on the entire continent. Qi Yu was happy to save as many demonfolk young as she could, but she was about to be plucked bald!! Theme:
