When the spiritual energy quietly revived, Lin Xiao found that the children in his class were getting more and more strange: when they cried, it would rain, and when they stamped their feet, it would cause earthquakes. As an ordinary kindergarten teacher who firmly believes in "love and professionalism", she took out "Kindergarten Teacher's Notes" and used child psychology and behavioral guidance methods to try to deal with these "problem children". It wasn't until the new fairy trainee teacher pulled her into a thousand-year-old tomb, pointed at the roaring beast on the mural and said, "Look, the great-great-great-grandfather of your class Xiaozhuang." Lin Xiao realized that she was facing an unprecedented "cub management crisis." Her mission has been updated: before relevant departments intervene, teach these little ancestors to hide their tails and control their instincts, and hold regular "alternative parent-teacher meetings" with the participation of mythical beasts, great demons and sword fairies. And her "Kindergarten Teacher's Notes" is quietly becoming the supreme secret book that affects the balance between the two worlds.
