Xiaoguang heard in Weiqi class that Weiqi lovers frequented Weiqi clubs, so he took Zuo Wei to play chess. Here, he met Toya Akira, the son of a famous chess player. In order to test Zuo Wei's strength, Xiaoguang rashly played against Toya Akira, and the result was a small victory over his opponent. He didn't know Toya Akira's identity, and he mistakenly thought that Zuo Wei's chess skills were normal, which made him deeply dissatisfied. However, Toya Akira was hit and frustrated. A few days later, Toya Akira challenged Xiaoguang again. Although he was very angry at Xiaoguang's contempt for Go, he was defeated by Zuo Wei again. Toya Akira repeatedly frustrated, the heart more depressed.
At the invitation of a friend, Xiaoguang went to Yelai Middle School to participate in the celebration. At the meeting, he cracked the Q&A of Weiqi Department and got to know the chess player Kaga. Kaga found Xiaoguang's chess skills superb, so he wooed him to participate in the junior high school inter-school Go competition. In the final of the team competition, Xiaoguang defeated the enemy with Zuo Wei's strength. As a result, Yelai Middle School defeated the prestigious Haiwang Middle School and won the championship. Unfortunately, it was revealed that Xiaoguang was still a primary school student, so he was disqualified from the competition.
