In the primary school science class, the teacher announced an exciting news - the school will hold a science king competition, and each class can only nominate one person to participate.After hearing the news, the students were all eager to try, hoping to show off their talents in the competition.

The squad leader felt that he was very promising, but at this time, Li Li recommended Che Chi, another classmate in the class.Che Chi usually has a rich reserve of knowledge and a strong interest in science, but he seems a little shy and nervous when facing the expectations of teachers and classmates.He coyly expressed that he did not want to participate, which surprised everyone.

Mi Xiaoquan saw Che Chi acting like this and decided to encourage him to participate.He ran to Che Chi and encouraged him to bravely accept the challenge and become the king of science.With Mi Xiaoquan's encouragement, Che Chi finally agreed to participate.

However, when school was over, Che Chi seemed very nervous.He and a man named Wu Siyuan were chatting in a low voice in the distance. Wu Siyuan looked very confident, even a little arrogant.He laughed at Che Chi for overestimating his abilities and gave him the nickname "Che Lao Er%".Faced with Wu Siyuan's provocation, Che Chi seemed to lack confidence and hesitated to speak.

Mi Xiaoquan and the others were very dissatisfied when they saw this scene and wanted to settle the score with Wu Siyuan.But Wu Siyuan felt that they were making too much fuss.He also provocatively proposed to compete with Che Chi to see who had more knowledge.Jiang Xiaoya wanted to make a bet with Wu Siyuan, but Wu Siyuan defeated him with his rich knowledge.

Mi Xiaoquan and the others decided to help Che Chi and let him win the game.They helped Che Chi review his knowledge and printed out Wu Siyuan's mugshot to try to give him moral support.Before the game, they also discovered that Wu Siyuan's family had very high expectations for him, which put a lot of pressure on him.So they took the opportunity to participate in volunteer activities and indirectly helped Che Chi.

On the day of the competition, Che Chi was very nervous, but his three partners kept cheering him on.Wu Siyuan also came to the competition with the expectations of his family.However, during the game, Wu Siyuan's button broke and he was unable to successfully answer.At this time, Mi Xiaoquan took the opportunity to repair the button, allowing Wu Siyuan to continue playing.But Che Chi did not cheat because of this. He refused the secret help from his partners and insisted on competing on his own strength.

In the end, Che Chi performed well in the Q&A session and successfully won the title of King of Science.Although Wu Siyuan had tampered with Che Chi's things during the game, Mi Xiaoquan and the others did not report him, but kindly explained to him the reason for the failure.Wu Siyuan also received education and realized his mistake.
