There was no specific information about the Sixth Bureau of the Overwatch Council in Joy of Life. Therefore, I don't know the situation of the Sixth Bureau of Joy of Life.

The Fourth Bureau of the Overwatch Council in Joy of Life was a department of the Inspection Council. It was responsible for supervising officials at all levels outside of Jingdou, including intelligence gathering and investigation work. The leader of the Fourth Bureau was Yan Ruohai. His son, Yan Bingyun, later became the leader of Northern Qi's underground organization. The power of the Fourth Bureau extended far beyond the borders of Dongyi and Northern Qi. All in all, the Fourth Bureau played a key role in maintaining the stability of the Qing Kingdom in Joy of Life.
Joy of Life's Overwatch Council was divided into eight departments, three of which were responsible for the development of drugs and weapons. The Third Bureau was managed by Fei Jie, one of the founders of the Overwatch Council. Fei Jie was very good to Fan Xian in the show because Fan Xian was his disciple. He hoped that Fan Xian could become the future successor of the Overwatch Council. The existence of the Overwatch Council had a profound impact on the Qing Kingdom. It was a special agency directly under the Emperor and was not subject to the interference of other officials. The Overwatch Council's functions included supervising officials, collecting intelligence, developing poisons and weapons, supervising foreign officials, protecting the director, assassinating and protecting, torturing and imprisoning enemies, and managing the printing of books and reviewing articles. The Overwatch Council's power could even surpass the Emperor's power, so the Qing Emperor loved and hated it. In short, the Overwatch Council in Joy of Life was a powerful secret agency responsible for monitoring and managing all aspects of affairs.
In Joy of Life, Zhu Ge was the director of the First Bureau of the Overwatch Council. He was responsible for supervising the officials in Jingdou and placing spies in various departments to gather intelligence. Zhu Ge's character was rigid, stubborn, and ruthless. He was initially loyal to the Eldest Princess Li Yunrui, but he was later bribed and betrayed the Overwatch Council. Zhu Ge was eventually killed by Chen Pingping, and Yan Bingyun took over as the director of the First Bureau of the Overwatch Council. Zhu Ge's ending was suicide.
The Black Knights, which the Fifth Bureau of the Overwatch Council was in charge of, were a special force in the Qing Dynasty. They were established by the Qing Emperor's personal decree. The Black Knights were known as the strongest cavalry in the world. They were the most powerful force in the Overwatch Council. Their main duty was to protect the safety of the Overwatch Council Director, Chen Pingping, especially when she was out of the capital to handle Council affairs. The combat strength of the Black Knights was not in individual combat, but in small-scale cavalry cooperation or group combat. They had performed outstandingly in the Qing Emperor's Northern Expedition. They had completed many surprise missions that spanned thousands of miles and captured Xiao En, the head of the enemy's spies. The deputy commander of the Black Knights, Jing Ge, was an important character in Qing Yu Nian. He led the Black Knights to display powerful combat strength in battle. The existence of the Black Knights had a profound influence on the Qing Kingdom. Their power could even surpass the imperial power of the supreme ruler.
