Cheng Ying was of high status and favor, and had three houses outside the palace. Two of them were in excellent locations, both in the inner city, very close to the imperial city.

The other house was more hidden, and Lu Jin had to go through some trouble to find out where it was. In the past few days, except for being on duty, he had been guarding outside Cheng Ying's three houses. The two houses near the imperial city did not have any servants going out to buy groceries every day, so it did not look like anyone was living there, with only a few servants guarding the yard.

The house in Yudai Hutong was different. Every day after half past the morning hour, not only would someone deliver vegetables, fruits and meat to the house, but there were also many more people moving around in the house than in the other two houses. Even the two gatekeepers were skilled in martial arts and were very alert.

As soon as Lu Jin got close to the house, he would be driven away.

Cheng Ying was in charge of the East Factory and had many experts under his command. Lu Jin sneaked into the house in Yudai Lane at night, but before he could climb over the wall to enter the house, he alarmed the people in the yard, causing a big commotion, so he had to leave in disappointment.

In the end, he failed to meet Liang Wushuang.

At that time, something happened in the Gongwei Division again. Zhou Fang, a doctor of the Dushuiqingli Division of the Ministry of Works, died in the Gongwei Division's secret prison. Lu Jin was unable to spare the time to guard Yudai Hutong, so he hired a woman to wander around Yudai Hutong every day, hoping to wait until the people in the house came out.

A carriage stopped at the entrance of Yudai Hutong. As Lu Jin walked out of the alley, a bony hand stretched out from behind the curtain. The curtain was opened and Yu Qizhe was sitting in the carriage with a book in his hand.

"Junior brother, why are you here?" Lu Jin asked in surprise.

"Get in the car and talk." Yu Qizhe lowered the car curtain.

Lu Jin walked to the carriage and said, "Junior Brother, the Guards have an urgent matter. I have to go there first."

"You come up first and I'll take you there in the carriage." Yu Qizhe's voice came from inside the carriage.

Lu Jin had no choice but to get on the carriage. After sitting down in the carriage, Yu Qizhe ordered the coachman to go to the Gongwei Division.

"Junior brother, what do you want to talk to me about?" Lu Jin asked.

Yu Qizhe put down the book in his hand, raised his eyes and asked, "Something happened to the Guardian Department?"

Lu Jin was surprised and asked, "Junior brother, how did you know? I just got summoned too, and Zhou Fang died."

"Go back to the Guard Bureau and don't get involved in matters related to Zhou Fang. It would be best if you can rest at home." Yu Qizhe said.

Lu Jin was puzzled and asked, "Why is that? Junior brother, you know I have a simple mind, so you should tell me the whole story so that I can have a clear idea in my mind."

Yu Qizhe closed his eyes and said in a low voice, "I just have some guesses. I'm afraid you will get involved in the dispute, so I can't be sure yet."

"What guess? Do you know how Zhou Fang died?" Lu Jin felt more and more confused. He was on duty at the Jinyiwei and didn't know the cause of Zhou Fang's death. His junior brother had only been in Beijing for a few days and had no connections, so how could he be more informed than him?

"If I'm not mistaken, Zhou Fang must have been silenced or hanged himself out of fear of punishment. If he committed suicide out of fear of punishment, it's fine. Although the people on duty in your Guard Bureau have failed to do their job, it's not a serious crime. If Zhou Fang was silenced, someone will have to take the blame." Yu Qizhe said lightly, leaning against the wall of the car.

After hearing this, Lu Jin understood, "Are you saying that someone in the Jinyiwei killed Zhou Fang?"

Although Zhou Fang did not die while he was on duty, he was summoned back at this time, which might mean someone wanted to frame him for the crime.

Moreover, he was appointed as a captain, in charge of guarding Zhou Fang, and the key to the secret cell where Zhou Fang was imprisoned was also in his possession.

Yu Qizhe then asked, "Has there been any progress in the case of clearing the silt from corrupt officials in the north these days?"
