Xiao Heng was besieged alone under the city tower. Shen Yurong stood on the city wall and ordered the archers to prepare. He laughed at Xiao Heng for being abandoned by others. Suddenly Xue Fangfei came riding on horseback. She was also ready, willing to accompany Xiao Heng to fight for Dayan, and allowed Shen Yurong to kill her again. Shen Yurong couldn't understand. He hated the powerful people for crushing him and Xue Fangfei, and thought it was not worth dying for Dayan. He instructed Xue Fangfei to kill Xiao Heng and wanted to go back to the past with her.
Xue Fangfei had a firm belief. She read out loud the names of the Longwu Army soldiers who had died in Wangcheng, and angrily accused King Cheng of letting a hundred Longwu Army soldiers die in Wangcheng in order to cover up the crime of abandoning the city. When Xue Fangfei called out their names, the Long Wujun present were touched. Here were their comrades and relatives.
Shen Yurong didn't want to hear any more and asked the archer to continue preparing. At this time, Situ Jiuyue arrived with Dazhao reinforcements. Shen Yurong took out the fish charm and ordered Yang Qing to kill him. Yang Qing could not resist, and anyone who disobeyed the order would die. Shen Yurong thought he could control it, so he laughed at Xiao Heng's incompetence and let the Longwu Army and the Allies kill each other.
Xue Fangfei showed no mercy. While Shen Yurong picked up the fish charm, she shot two arrows to injure Shen Yurong's palms. Situ Jiuyue flew over with Qinggong, snatched the fallen fish charm and handed it back to Xiao Heng. Xiao Heng and Xue Fangfei temporarily separated and led Long Wu's army back to seek revenge on King Cheng.
Shen Yu endured the pain and pulled out the arrow from his palm. Xue Fangfei walked up to him and asked him to accept Dayan's legal sanctions. Shen Yurong wanted to stay, but he blamed himself for taking the wrong step, thinking that he should not have passed the No. 1 exam in the first place so that he and Xue Fangfei could live a good life in Huaixiang. Xue Fangfei turned around and looked up at the moon, hoping that Shen Yurong would be born rich and a pure good person in his next life.
After Xue Fangfei left, Shen Yurong stood on the tower, played the tune that the two had shared, and jumped off the tower with a bang. Xue Fangfei stayed for a moment, but still walked forward without looking back. Shen Yurong looked at Xue Fangfei's back and her vision blurred.
Xiao Heng asked Long Wujun to capture King Cheng. King Cheng tied up Concubine Li and threatened Xiao Heng with her life, believing that Concubine Li was the most beloved concubine of Emperor Hong Xiao. Concubine Li hoped that Xiao Heng would not tell the emperor about the palace maid, so she deliberately committed suicide by following the sword of King Cheng. King Cheng panicked, and Xiao Heng took the opportunity to stab King Cheng. King Cheng begged for mercy, but Xiao Heng showed no mercy and killed him with one sword.
After the death of King Cheng, the remnants of the northern border rebelled on the grounds that something had happened to King Cheng. The imperial court officially sent Xiao Heng and others to suppress it. Li Zhongnan and Li Jin were interrogated and executed for colluding with traitors, Shen Yurong's home was ransacked, and Shen's mother and Shen Ruyun, who had fled to the countryside for refuge, were also arrested and interrogated. Jiang Yunxing and Yang were expelled from the Jiang family. Calm finally returned to the capital.
Emperor Hong Xiao looked at Concubine Li's portrait and his eyes were filled with tears after learning her last words before her death. Xiao Heng set out three days later, and Emperor Hong Xiao hoped that he would follow him with heavy troops. Xiao Heng was worried that there were remnants of King Cheng in the capital, so he only led the Longwu Army to the north.
Xue Huaiyuan's condition improved and he could recognize everyone. Xue Fangfei was relieved to know that. Xue Huaiyuan recognized Xiao Heng and supported Xue Fangfei's approach. Xue Fangfei confessed to Xiao Heng, suggesting that he renovate the Duke's Mansion. Xiao Heng giggled all day after hearing this. The two came to the cemetery to see Jiang Li. Xue Fangfei seemed to see Jiang Li appear, and Jiang Li thanked her for clearing her stigma.
Xue Fangfei and Xiao Heng got married and entered the bridal chamber. Xue Fangfei gave the civet cat jade pendant to Xiao Heng. After getting married, the two planted wintersweets with their own hands, and Xiao Heng promised that when the wintersweets bloom, it will be the day of his triumph. Seeing Xiao Heng's leaving figure, Xue Fangfei was reluctant to leave.
Jiang Yunbai resigned from his job and moved to Yongzhou with his family. Before leaving, he was worried about Xue Fangfei. Xue Fangfei said that she would wait for Xiao Heng, otherwise she would be a widow for the rest of her life. She confessed her identity, but Jiang Yunbai already knew it, but this was also the pain deep in his heart. After the Jiang family left, Ye Shijie recognized Xue Fangfei as his sister, hoping to help her in the capital.
Xue Fangfei went to water the wintersweet every day, waiting for Xiao Heng to come back, year after year, spring passed and autumn came. Xiao Heng suppressed the remnants of the northern border and sent troops to attack on behalf of the country. Longwu's army suffered heavy casualties. Lu Ji and Wen Ji were also killed by arrows, leaving only Xiao Heng. On the battlefield, the Dai army continued to attack. Xiao Heng held the jade pendant given by Xue Fangfei in his mouth and looked firmly at the sky.
Finally, when the wintersweet blossoms bloomed, Xue Fangfei, dressed in red, ran under the wintersweet tree and watched them bloom. Suddenly, the sound of a horse racing behind her drew her back. A man in red wearing a civet cat jade pendant was running towards her...
