Gan Long heard that Wei Zi had lost his army and strength.

At that time, because of the Jinchuan War, Gan Long sent back-office workers to fight. Neiqin is arrogant and rude to the Han people in the army and will not command a losing streak. After the defeat, he asked Gan Long to send Tibetan lamas and Taoist priests to the front to support him. This made Gan Long furious. Later, Gan Long received a tip-off, saying that without his relatives, he could not avoid the war, and told the soldiers not to act rashly. At this time, the unbearable Qianlong ordered someone to send a knife and let his ex-wife commit suicide. In this way, my dead wife, who was very popular in Qianlong period, was given the death penalty.

Niu Kelu, an aristocrat in the Qing Dynasty, was an office worker, and his grandfather was a founding hero of the Qing Dynasty. The back office inherited the title in Yongzheng period and began to move towards its own political path in Qianlong period. In the early years of Qianlong, in order to consolidate his dominant position, Qianlong began to have distrust of the old minister left by his father, and he was determined to cultivate his own power. So Zhang and E Ertai began to be left out by Qianlong. Neiqin stepped onto the political peak step by step with family power and political skills. For Gan Long's favor, he knew it was hard-won, and he was very cautious at ordinary times, whether in the DPRK or in life.

During Qianlong's southern tour, some local officials wanted to put in a good word before the emperor in exchange for a good job. They prepared generous gifts for their former relatives, and they all refused. After returning to Korea, the back office reported this to the emperor, and the emperor trusted the back office more. Later, the back office was made a first-class public, and at the same time assisted the prime minister's affairs. Soon after, in order to weaken the arrogance of E Ertai and Zhang, the back office was promoted to one of the most important military ministers by Qianlong. At this time, the back office became the most powerful minister in the dynasty.

It is such a powerful minister who is deeply loved by the emperor. His performance in a battle completely ruined his future and his life.
