The post of "Nine Gates Commander" was established during the Qing Dynasty. It was called "Nine Gates Internal Official Commander" during the Ming Dynasty. Initially responsible for guarding the imperial palace, it later became responsible for guarding the main gates of the capital, typically held by loyal and high-ranking eunuchs.

The Wucheng Bingmasi (Five Cities Military Command) was the equivalent of the later Public Security Bureau, responsible for patrolling the capital, arresting thieves, clearing streets and drains, and managing prisoners and fire bans. It had one commander, a sixth-rank official, and four deputy commanders, each of seventh-rank official.

Bi Ziyan understood as soon as he heard it. The emperor had already taken control of the Beijing camp and had the defense and security of the capital firmly in his hands. He was either going to take action against the powerful and noble relatives, or to prevent them from causing trouble.

He nodded when he understood, and Bi Ziyan didn't ask any more questions, so as not to embarrass his brother. Being able to reveal these things to him was already extremely rare, and it would be suspected of revealing the emperor's will.

Cracking down on official business was obviously also a boon to the Imperial Bank he was about to take over. Many powerful officials did not engage in business directly, but instead invested in or lent money to businessmen.

Cutting off this road would be beneficial to the development of the Imperial Bank's loan business.

Moreover, the Imperial Bank's loan interest rates are obviously lower than those of individuals and private lenders, and it is still very competitive.

"Your Majesty, you are diligent and diligent in governing the country. You are wise and powerful, and you embody the spirit of a wise ruler." Bi Ziyan pondered for a moment before slowly speaking, "As your brother, you are also the Minister of Finance, and I am well aware that the Liaodong war is extremely costly. Without strategies to increase revenue and reduce expenditure, the national finances may be in danger of collapse."

Bi Zisu nodded and said, "Brother, you are good at managing finances and have economic capabilities, so your judgment is correct. I will only investigate and prosecute officials for their illegal activities, and rectify the rules and discipline for Your Majesty."

Bi Ziyan knew his brother's temper. He knew that being responsible and conscientious in the Censorate would definitely offend many officials and dignitaries. However, being diligent in the king's affairs was his unshirkable duty.

Bi Zisu's appointment as Chief Censor of the Censorate, along with the six ministers of the six ministries, was a meteoric rise. With such a gift, how could he not devote all his energy to repaying the emperor?

As he was speaking, a servant came to report that someone from the palace had been sent to summon Bi Ziyan to the Qianqing Palace for an audience.

Bi Ziyan did not dare to delay. He quickly tidied up his clothes and appearance, and followed the palace servants to meet the emperor.
