Duan asks why his deskmate is so amazing. It's just that he's the first to answer the first question. The second question is more difficult, and Duan and his classmates will have to solve the second problem in a slightly longer time frame. The students from Linjiang No. 6 High School answer the second question first. Duan congratulates the students from the school for their hard work. They're the ones who won the first half of the competition, but Duan's team lost the second half. He's annoyed that Duan didn't write the answer to the draft papers on his own hand. Three hours later, Duan wins the individual competition. The individual competition is like a lottery, except that the players have to answer questions within a specified time. The players can't bring anything that isn't related to the competition. They don't even have to whisper to each other. The first question is about finding all the triple sets of odd numbers, which Duan thinks is confusing. The head teachers of the four schools have issued the questions for the tournament, but the students are confused by the lack of details. The time for the competition has passed, and the students have only ten minutes to answer all the questions.
