Devil's Hairpin

This film is a children's fantasy movie. The Happy King (played by Lu Xiaopin) and the Happy Queen Huanzhen (played by Juanzi) use magic to make children only have fun and forget to study, and at the same time steal children's energy to make themselves immortal. Wen Wen (played by Yue Wei) dreamed that Huan Zhen gave her a hairpin, and a voice warned her not to bring it because the devil would possess her. The robot on the table calls himself Stinky Ball, and he and the "Mr. Will" seen in Wenwen's dream simultaneously stop Huan Zhen from harming people everywhere. Qiangqiang (played by Shi Chen) did not perform as well as before in the exam. Huanzhen sent the card in time and told Qiangqiang that if he took the exam with him, he would be invincible. At the same time, Wenwen found a hairpin that had flown to him at home. After taking it with him, he was like a god who could do anything during the exam. "Mr. Will" and Huan Zhen were struck unconscious during the fight, and the energy ball in the magic cave continued to expand, making the Happy King and Queen laugh wildly. One day, the children walked into the magic cave under the control of Huan Zhen's will. Wen Wen was surprised to find that she had become an old woman, while Qiang Qiang and Xiaolu (played by Li Longfei) had become old men...
