Guo Jing teamed up with the Beggar Clan to search for Huang Rong, but they were unable to find any clues about Huang Rong for a month. Guo Jing and Lu Youjiao went north to look for Huang Rong and accidentally encountered a battle between Jin soldiers and Mongolian soldiers. Guo Jing helped the Mongolian soldiers defeat the Jin soldiers. Guo Jing met Torre again, and Torre asked Guo Jing if he wanted to return to the grassland together. Guo Jing was hesitant. Lu Youjiao asked Guo Jing to go back to the grassland to see his mother first. He led the Beggar Gang brothers to continue looking for Huang Rong. If there is any news, Guo Jing would be notified as soon as possible.
Guo Jing returned to the grassland, and both mother and son were very happy to meet each other. Guo Jing told his mother about his experience this year. Li Ping saw that his son liked Huang Rong, but was also worried about Guo Jing's engagement with Princess Huazheng. Guo Jing wanted to tell the truth to the Khan to terminate the engagement, and Li Ping said that she would support her son no matter what choice he made.
Guo Jing came to see the Great Khan and wanted to cancel his marriage to Princess Hua Zheng. The princes thought that Guo Jing's repeated attempts to cancel his marriage to Hua Zheng were too humiliating to them and wanted to teach Guo Jing a lesson. Hua Zheng appeared to defend Guo Jing. He even resorted to committing suicide to force his father and brother to give in. Hua Zheng asked Guo Jing what made her inferior to Huang Rong. Seeing that Guo Jing was unwilling to answer, she said that she would always wait for Guo Jing. Temujin gave Guo Jing an opportunity to make meritorious service and asked Guo Jing to follow him on the Western Expedition. Temujin also named Guo Jing Nayan and gave him 10,000 troops to follow them on the expedition.
Guo Jing knew nothing about marching and fighting, but thinking of Yue Fei's Wu Mu suicide note, Guo Jing studied it painstakingly, hoping to be helpful. Lu Youjiao and Lu Guanying learned that Guo Jing was about to march to the west, and they came to find Guo Jing to prepare for help. The Beggar Clan and others failed to find any news about Huang Rong. Lu Guanying told Guo Jing that Master Guo Jing had gone to Baituo Mountain to look for Ouyang Feng, and asked Guo Jing not to ask for help. Worry. Now Song and Meng are jointly attacking the gold, and the heroes from the Beggar Clan and Guiyun Village are coming to help.
Guo Jing accidentally understood many of the military tactics in Wu Mu's suicide note. Lu Youjiao took the initiative to explain them one by one to Guo Jing. As a result, Guo Jing grew up rapidly and successfully won the first battle. Guo Jing once again asked Lu Youjiao about the military strategy, but Lu Youjiao still refused to explain it until tomorrow. Guo Jing was suspicious and followed Lu Youjiao, but unexpectedly met Ouyang Feng in the woods who was looking for Huang Rong. Ouyang Feng wanted to capture Guo Jing and force Huang Rong to show up. The confrontation between the two attracted everyone from the Beggar Clan, and Ouyang Feng was accidentally injured by Guo Jing. In order not to attract attention, he could only leave temporarily.
Temujin was angry because he failed to attack Samar Seoul. Now he was in a dilemma. Lu Youjiao made a suggestion. Guo Jing also guessed from it that it was Huang Rong's idea and asked Lu Youjiao to take him to see Huang Rong. Lu Youjiao saw that he couldn't hide it from Guo Jing, so he had to take him to see Huang Rong. Lu Youjiao told Guo Jing that the gang leader was at the top of Tumu Peak. In order to see Huang Rong not afraid of the risk of being thrown to death, Guo Jing tried to climb the peak again and again. Lu Youjiao couldn't bear Guo Jing's injury and gave him an idea to build a climbing ladder using mutton legs to climb to the top of the mountain.
Guo Jing and Huang Rong met again, and they hugged each other to express their longing. Guo Jing apologized because he had misunderstood Huang Yaoshi and Huang Rong, and he also confessed that he was sincere to Huang Rong. Guo Jing asked Huang Rong how to escape. Huang Rong explained that she deliberately took Ouyang Feng to Guiyun Village, used Guiyun Village's Bagua array to trap Ouyang Feng, and took the opportunity to escape. Later, Huang Rong wanted to return to Peach Blossom Island, but Ouyang Feng chased her all the way, so she could only go all the way north to the grassland to find Guo Jing. She sneaked into the military camp, and Ouyang Feng also sneaked into the Mongolian military camp to find her. In order not to cause trouble to Guo Jing, Huang Rongcai never looked for Guo Jing.
Guo Jing asked Huang Rong to stay with him in the future and never leave him again. Huang Rong noticed that Ouyang Feng was also nearby, and deliberately mentioned the Nine Yin Scriptures to Guo Jing. She said that she would translate the Nine Yin Scriptures and write them down silently, and in order to prevent Ouyang Feng and the others, they could not take the Nine Yin Scriptures away from the top of the mountain. Ouyang Feng heard the conversation between the two and decided to wait for them at the top of the mountain. After Guo Jing and Huang Rong came down from the top of the mountain, they burned the ladder made of mutton legs, which was bound to trap Ouyang Feng to death on the top of the mountain. Ouyang Feng waited at the top of the mountain until midnight but did not find Guo Jing and Huang Rong. He scolded them for being dishonest.
The army had been besieging the city for several days and was unable to capture it. The Mongolian soldiers were already facing a shortage of food, and Guo Jing was in a bad mood because of this. Then Huang Rong saw Ouyang Feng leaping down from the top of the mountain, and she thought of a way to attack the city. She asked Guo Jing to order the soldiers to cut the tents into wings and use them to make leather umbrellas to help the army attack the city.
