In the 83rd edition of Legend of the Condor Heroes, I remember an episode in which Guo Jing learned the plough Beidou array method and helped Quanzhen Qizi win together. Which episode is that?

In the original book, Guo Jing caught a glimpse of the plough Beidou array in the darkroom while watching the healing of the seven sons of the East Evil War, and realized the magical power between the fingers (Guo Jing is stupid, but he is a martial arts wizard). When I was looking for Eden to save Huang Rong, I accidentally bounced off Yu Qiao's ploughing weapon with my fingertips. I was very impressed to see Eden's healing skill to acquire a Yang finger. Seven sons joined hands to draw with Dong Xie at most. By the time Guo Jing of Yan Language Building joined the plough Beidou array, Dongxie had already lost. When it was misty and rainy, Dong Xie was able to break the plough Beidou array, but Guo Jing beat him to seal the Beidou position. Only later, Guo Jing explained the misunderstanding between Dong Xie and Qi Zi, and they didn't want to fight, and then the story didn't go on.
