In May of A.D. 1723 (the first year of Yongzheng), Yongzheng issued an imperial decree: "If there is a place to dispatch troops and take meals, the frontier defense minister, the governor of Sichuan, Shaanxi and Yunnan shall handle it according to Nian Gengyao." In this way, Nian Gengyao was in charge of all the affairs in Xixiang, and actually became a confidant of Yongzheng at the front line of Xixiang, and his power position was actually above the governors such as General Yan Xin of Fuyuan. Yongzheng also warned local officials in Yunnan, Guizhou and Sichuan to obey Nian Gengyao's orders. In the same year 10, Tenzin Rebellion occurred in Qinghai. The situation in Qinghai suddenly became chaotic, and Xiqiao war resumed. Yongzheng ordered Nian Gengyao to take over as General Fuyuan, and the commander-in-chief stationed all troops in Xining to command counter-insurgency.

At that time, Nian Gengyao had just arrived in Xining, and the army had not assembled yet. When Robert learned of it, he led an army to sneak attack and directly captured Xining. Nian Gengyao rate about dozens of people sitting on the tower, without panic. Lu Bu Zang Danjin thought there was fraud and led the army to retreat. Nian Gengyao ordered the soldiers to attack the thief base. The enemy thought that Nian Gengyao and Serenade were not prepared to drive Tufan's current team at Table Mountain. The gun went off, and death doesn't count. Yue Zhongqi's soldiers arrived and directly attacked the enemy camp. Rob Zangdanjin fled in defeat, and only a hundred people fled.

/kloc-at the beginning of 0/724 (the second year of Yongzheng), the final stage of the war came, and Nian Gengyao ordered the generals to "go their separate ways and destroy their nests". Military forces from all walks of life braved the snow and marched day and night, quickly mopping up the remnants of the enemy and winning a great victory. Nian Gengyao's reputation as "General 2000" has since deterred Xiqiao, enjoying a high reputation in the ruling and opposition circles.

Yongzheng was overjoyed at the success of the war to pacify Qinghai, so he gave Nian Gengyao a special reward: before that, Nian Gengyao had won the third class merit and the second class merit successively for his military achievements in pacifying Tibet and pacifying the Guoluoke rebellion. This time, he was promoted to a first-class public by careful planning and surprise. In addition, a viscount was awarded, which was inherited by his son Nian Bin. His father was made a first-class public when he was young, plus the title of a teacher. At this time, Wei Town, Nian Gengyao, northwest, can participate in Yunnan government affairs and become the main confidant minister of Yongzheng in other provinces.
