Xiaoman, a primary school student, was worrying about the heavy Mathematical Olympiad questions. By chance, he got a "magic homework book" from the tree spirit grandpa under the century-old sycamore tree on campus that could automatically complete his homework. However, this miracle is not free. It requires Xiao Man to remain absolutely honest, otherwise the shadow will mutate.
As Xiaoman continued to use magic to be lazy and cover up the truth with lies, his shadow began to become transparent and funny, and even "cut" the connection in full view of the public, and fled to the mysterious "Shadow Kingdom". In order to regain the shadow, Xiaoman and Chen Mo, a transfer student who also lost his memory due to reliance on magic, broke into the underground world where black and white were reversed and full of temptation.
In the trial hall of the Shadow Kingdom, there is no magic to cheat. They must rely on their own sweat to solve the problems they once escaped before dawn. This is not only a fantasy adventure of searching for the shadow, but also a spiritual transformation about honesty, hard work and self-salvation. When the first ray of morning light illuminated the window sill again, Xiao Man finally understood that the greatest magic in the world was actually hidden in the efforts of every stroke.
Intention: There is no shortcut to growth, honesty and hard work are the strongest magic to the future.
