In the later years of Jiajing's reign in the Ming Dynasty, Japanese pirates were rampant in the southeast. On the eve of the decisive battle, there was a mutiny in Yulin Town in the northwest. The famous general Chang Yun rebelled from the border and besieged Yulin. Mongolia, rebels, horse thieves, all forces are ready to move. In order to fight against the Japanese, the chief minister of the cabinet, Yan Song, blocked the news and secretly appointed Mu Sanguan, a member of the Jinyi Guard Qianhu, to go to the northwest to quell the rebellion. At the same time, the Qing faction headed by Xu Jie and Gao Gong conspired to overthrow Yan and make King Yu the crown prince. Mu Sanguan uncovered Master Wen's plot to hold the prefect hostage in Suide City, escorted military supplies to Yulin with the powerful general Ma Gui, and joined forces with Chu Qianjin to kill Master Wen, defeated thousands of horse thieves, and then went north to the grassland to seek help from Samozhe, the master of Yunzhong Fort. Samozhe made a condition that as long as he had a jar of pickles from Liuxinju in the capital, he would help him put down the rebellion. Mu Sanguan and Chu Qianjin rushed to the capital, but were ambushed by Ren on the banks of the Sanggan River. Chu Qianjin died in a bloody battle, and Fu Guiyan showed up to help. At Dongsheng Inn, Gao Wuye reminded Mu Sanguan that the situation in the court was extremely unfavorable to Yan Dang and advised him to make early plans. Yan Song left Beijing after becoming an official. Mu Sanguan brought pickles to send him off, and Yan Song gave him some parting words. Mu Sanguan and Fu Guiyan rushed back to the grassland. Yunzhong Fort had been looted by Chang Yun, and Samozhe was nowhere to be seen. Mu Sanguan found Samozhe's cavalry in Wuliangsuhai, and together with Fu Guiyan and Lao Shi, they attacked Hengshan Village and killed Luo Changgeng. Outside Yulin City, rebel cavalry gathered; at the top of Yulin City, the defenders were heavily armed with artillery. Mu Sanguan went out alone to play a chess game. Chang Yun immediately responded to the challenge and committed suicide in front of the formation. The situation in the DPRK took a turn for the worse. In the grassland outside the Great Wall, the white horse is blowing in the west wind, and Mu Sanguan returns with his beauty.
