After entering the customs in the Qing Dynasty, the young Kangxi ascended the throne. Kangxi was the emperor who made the greatest contribution to the Qing Dynasty. Kangxi cut San Francisco to eliminate the curse for future generations, and he also killed Ao Bai to regain political power for himself. Later, Kangxi passed the throne to Yongzheng. During the Yongzheng period, there was a very powerful general, and he was Nian Gengyao. In the Kangxi period, Nian Gengyao passed the Jinshi exam and entered the official career, while Nian Gengyao was still a little official, which was not outstanding. Nian Gengyao was familiar with the Four Books and Five Classics since he was a child, hoping to gain fame and honor in the future. Nian Gengyao did not bear the hardships of studying hard for ten years, and finally gained fame through layers of screening. Because of his good political achievements, Nian Gengyao was soon promoted as the governor of Sichuan. Nian Gengyao appreciated Kangxi's esteem and wrote a letter to express his gratitude. At that time, Nian Gengyao knew etiquette and knew the pecking order. After taking office, Nian Gengyao made an in-depth investigation of the people's feelings in Sichuan and recorded all the problems in some places. After returning to Nian Gengyao, he invited his colleagues to discuss and solve these problems. When he worked in Sichuan, he solved many problems for the people and was praised by the people. Later, Kangxi also wrote in recognition of Nian Gengyao's contribution and placed high hopes on him.

Later, Allabo sent troops to invade Tibet, and Nian Gengyao began his life as an iron horse. He observed military affairs many times and provided support for military logistics. Nian Gengyao was appointed governor of Sichuan on the recommendation of his master Yin Zhen, and Nian Gengyao began to have the power to control the army. Under the careful deployment of Nian Gengyao, the whole army gained a new record in fighting against the rebels. Nian Gengyao's army returned home in triumph. After Nian Gengyao returned to Beijing, there was another rebellion in Qinghai. Nian Gengyao was once again assigned to pacify. This time, Nian Gengyao used tactics to pacify the rebellion in Qinghai easily.

At that time, officials in the Qing Dynasty all had their own imperial patrons, and these patrons were usually the sons of the emperor. During the Kangxi period, the imperial court was roughly divided into three factions, one was the prince, and the officials of the prince were all over the world. There is also a group of people who belong to the Eight Sovereigns, whose power is second only to that of the Prince. The other faction is the people of the four princes. At that time, the only faction of the four princes was thirteen princes, which was the weakest faction in the DPRK. However, the group of the Eight Sovereigns and the Four Sovereigns knew that if they wanted to ascend the throne in the future, they would have to pull down the Prince together. In the end, the prince was pulled off the horse by their two big groups because of corruption and rebellion. At that time, Nian Gengyao was a slave of Yin Zhen, the fourth sovereign, so Yin Zhen recommended Nian Gengyao for many times.

Later, after Kangxi's death, Yin Zhen, the fourth grandfather, succeeded to the throne, and Nian Gengyao's career became more spacious, because he followed the right master. But soon there was another rebellion in Qinghai, and Nian Gengyao was appointed as General Fuyuan and sent to Qinghai to put down the rebellion. Nian Gengyao lived up to expectations and once again put down the rebellion in Qinghai, and Yongzheng made Nian Gengyao a first-class public, which is also the highest honor of Nian Gengyao.

Nian Gengyao monopolized power in the northwest in his later period, and his character became more and more arrogant. He acted first and then acted second in dealing with affairs for many times, and his achievements were almost overshadowed by Yongzheng, which made the relationship between Yongzheng and Nian Gengyao suspicious. Later, Nian Gengyao, who was on his high horse, left his post and returned to Beijing alone without Yongzheng's recall. This was a violation of the military orders of the Qing Dynasty, and it was also the foreshadowing of Nian Gengyao's final demise. In the end, Yongzheng couldn't stand Nian Gengyao's arrogance, and loudly criticized Nian Gengyao in the court and pointed out many crimes of Nian Gengyao. Nian Gengyao was eventually jailed, and later Yongzheng ordered Nian Gengyao to commit suicide in prison. Since then, the most powerful general in the Qing Dynasty has come to an end.
