Faced with the chaos, epic farces and serial mysteries of the Magic Academy, they use wit and friendship to deftly resolve the crisis, but unexpectedly involve themselves in a dark conspiracy that has been hidden for many years. In the chase scene where they laughed and wiped sweat all the way, the teenagers gradually revealed the grudges of the old magic family, the unprecedented magic disaster and the ultimate secret of the world. When Lester finally understood that "the most amazing magic is to believe in yourself," it also pushed the gears of the world's destiny. The whole story has ups and downs, joy and joy, and finally ends successfully with the joyful vows of magic and growth.
