Following Zhang Yunian's instructions, Jiang Zuiyao walked out the door and arrived within a few steps.

It was a narrow house with no windows. The walls were made of solid dark gray bricks. In front of the heavy iron door stood a guard in leather armor with a knife. When he saw Jiang Zuiyao standing in front of the door, he stopped and immediately shook his hand.

Holding the sword tightly at his waist, he asked cautiously: "Who is coming?"

Jiang Zuiyao didn't know who he was, so he replied: "I am the second commander of Yinfeng Hall. Master Zhang asked me to come here."

The guard looked at Jiang Zuiyao in surprise, as if he didn't expect it to be a woman, but he didn't ask any more questions and just said: "Show me your embroidery pattern."

Jiang Zuiyao lifted up her sleeves and showed her left arm to him.

The guard took a look at it and saw that it was the pattern of the new Second Commander he knew. In addition, after seeing the newly tattooed totem, he immediately identified Jiang Zuiyao. He immediately released his sword, clasped his fists and saluted, "I see you, Your Excellency, the Second Commander."

Jiang Zuiyao held the box in her hand and carefully looked at the person in front of her.

This man is about seven feet tall, thin, about 20 years old, wearing a purple robe embroidered with green patterns, and has a dignified appearance.

Jiang Zuiyao immediately asked: "Who are you?"

The man in front of me replied: "I am the guard of Yinfengtang, and I will be in charge of guarding your office in the future."

"I'm asking what your name is."

"You can just call me Mu Yan in the future. This is my subordinate's embroidery pattern."

Jiang Zuiyao glanced at the embroidered pattern on Mu Yan's left arm, and she immediately recognized it as the totem of a low-level guard from the Imperial City Division. It seemed that they had just been dispatched.

You can't ask anything about the rest. This is the rule of the Imperial City Department. Everyone's identity is confidential, and even if they know it, they must not be disclosed to anyone.

Therefore, we are not allowed to ask questions about where Mu Yan's family lives or who his last name is.

Jiang Zuiyao took out the key from the box and opened the iron door, revealing everything in the house.

The room is very small, so small that it can only accommodate seven or eight people. It only has a table, a chair, and a small bookshelf. It can't be simpler.

Jiang Zuiyao walked in, but Mu Yan did not follow him. Instead, he closed the door and remained guarded at the door.

A room with no windows and a small space immediately becomes completely dark.

After lighting the candle, Jiang Zuiyao stood in this small room, feeling depressed, and even her breathing became less comfortable.

Because I was new here, there was nothing in the room except the furnishings. The table and bookshelf were empty.

I looked at the keys in my hand. There were three in total. One was for opening the door to the house. Where were the other two?

Jiang Zuiyao started to investigate, trying to find the lock with the two keys, but she couldn't find any locked box or door.

After searching for a while, I discovered something unusual under the chair.

The floor was made of stone tiles, built one by one, tightly and seemingly without any gaps, but the sound of the nine stone tiles under the chair being knocked was hollow.

Jiang Zuiyao simply knelt on the ground and looked carefully, and then she discovered that there was a small keyhole in the gap between the stone bricks. This was because her key contained a key as big as an ear spoon. At first, she was curious about what kind of lock it opened.

Only now do we know this.

It is conceivable that such a small key and such a small keyhole are extremely difficult to find hidden in the gaps between stone bricks.

She inserted the key into the keyhole and twisted it slightly, fearing that she would break the key if she applied too much force.

Until I felt the direction of the lock, I twisted it hard to the right. With a "bang" sound, nine stone bricks were instantly bounced up, overturning the chair on top.

Mu Yan outside the door heard the noise, but did not come in. He just asked: "Sir, are you okay?"

Jiang Zuiyao replied: "It's okay."

Mu Yan stopped talking, didn't come in, and didn't even open the door.

The nine stone bricks were very heavy when they were opened, and Jiang Zuiyao had to use a lot of strength to open them.

Later, Jiang Zuiyao realized that this was actually a secret door. Under the stone bricks were long steps leading underground, just like when Zhang Yunian took her underground when she first came to the Imperial City that day.

The passage was so narrow and thin that there was only room for her alone, and it was completely dark below with no light at all.

Jiang Zuiyao had no choice but to hold the candlestick in one hand and the box in the other and walk down.

The further you go down, the darker it becomes. A small candlestick cannot illuminate the distance at all, so that Jiang Zuiyao has to bend her body slightly, and the weak light can only see the road under her feet. Fortunately, the steps are neatly laid out, so it is not difficult.

Walk..

But having reached the end, Jiang Zuiyao held up the candlestick and looked at it. Just like last time, there were many rooms underground, all locked, and each room was independent. The surrounding roads were complicated and connected in all directions.

Jiang Zuiyao walked straight forward, and after walking about twenty or thirty steps, she reached a room.

This room is directly facing the steps, so it should be this one.

Putting down the box, he took out the key and picked out the only key that had not been found in the lock. He held up the candlestick and shined it on the copper lock. He almost had to press it in to see the keyhole. His forehead was a little hot because of the candlelight. Jiang Zuiyao insisted on putting the key into the lock.

By comparing them with the eye, you can tell from the shape, and they indeed match.

The key was inserted smoothly into the keyhole, and with a twist, the lock opened.

Jiang Zuiyao quickly opened the door. When she pushed the door, a burst of dust rose up. She was caught off guard and lost her eyes. She quickly raised her hand to fan the flying dust and rubbed her eyes.

It's still black, very black, so black that you can't even see it.

With the candlestick, she finally found the candle lamp on the wall. Jiang Zuiyao lit it, and the room lit up instantly.

This room is not empty.

There are four sides of the house. There is nothing on the side with the door. The remaining three sides are lined with iron bookshelves. The bookshelves are filled with books. The overall look is like three walls made of books. In the center of the house

There is a desk, which is covered with dust.

It seems that this place once belonged to someone, but it has been idle for a long time.

There was no water in this place, and there was no way to clean it. Jiang Zuiyao didn't mind it, so she started to look through the books on the bookshelf, and when she picked one up, she realized that it was not a book at all, but a handwritten file, which clearly recorded the name of Yinfeng Hall.

Things that have been done before.

As the words came into view, Jiang Zuiyao discovered that they were all ulterior secrets. When and where the incident occurred, who went to investigate the information, and what the information was. It was recorded clearly. Every piece of information was clearly recorded.

It took me seven or eight pages to finish.

After reading seven or eight books like this, Jiang Zuiyao discovered that the handwriting was different. It seemed that it was not written by one person. In addition to the years recorded above, which were several decades apart, it seemed that the deputy commander of the Imperial City Division had been changed by several people.

.

Jiang Zuiyao was deeply attracted by the words above. After a while, two or three hours passed. She read about a dozen books and learned some things that she had never known before. Those things, as a government woman, she might never be exposed to in her lifetime.

.

Jiang Zuiyao put away the box that Zhang Yunian gave her. This place was naturally safe. She locked the door and went back to the house. She locked the cellar door again. When she went out, it was already dark.

Mu Yan was still there. When he saw Jiang Zuiyao coming out, he immediately bent over and waited for her to speak.

Jiang Zuiyao asked: "Will you stay here forever?"

Mu Yan replied: "I am only responsible for guarding during the day. At night, someone will come to replace me. Don't worry, sir, there are people guarding here at all times. It is very safe."
