According to Zhang Yunian's instructions, Jiang Zuiyao went out and walked a few steps away.

It was a narrow room, with no windows, dark gray bricks and solid walls, and a leather-clad armor guard with a knife stood in front of the heavy iron door. ”

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

The guard looked at Jiang Zuiyao with a little surprise, as if he didn't expect it to be a woman, but he didn't ask anything, only said, "Show me your embroidery." ”

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

The guard glanced at it, it was the pattern of the new second commander he knew, and when he saw the totem of the new thorn, he immediately identified Jiang Zuiyao, and immediately let go of the treasure knife and hugged his fist and saluted: "My subordinates see the second commander." ”

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

The man was about seven feet tall, thin, about twenty years old, wearing a purple robe embroidered with green stripes, and his appearance was dignified.

Jiang Zuiyao immediately asked, "Who are you?" ”

The man in front of him replied: "The subordinate is the guard of the Yinfeng Hall, and the supervisor will guard your office in the future." ”

"I'm asking what your name is."

"You can call me Mu Yan in the future, this is the embroidery pattern of my subordinates."

Jiang Zuiyao glanced at the embroidery on Mu Yan's left arm, and she immediately recognized that it was the totem of the low-level guards of the Imperial City Division, and it seemed that it had just been dispatched.

The rest of the people can't ask anything, this is the rule of the Imperial City Division, everyone's identity is confidential, even if they know, they must not be revealed to anyone.

Therefore, you can't ask where Mu Yan's family lives and who their surname is.

Jiang Zuiyao took out the key in the box, opened the iron door, and everything in the room came into view.

The room was small, small enough to fit seven or eight people, with only a table, a chair, and a tiny bookshelf.

Jiang Zuiyao walked in, but Mu Yan didn't follow up, but closed the door and still stood at the door.

The windowless room and the small space were all dark.

Lighting the candle, Jiang Zuiyao stood in this room, only feeling depressed, and even breathing became not so pleasant.

Because it was new to the house, there was nothing in the room except for the furnishings, and the tables and bookshelves were empty.

I looked at the keys in my hand, there were three of them, one was to open the door of the house, and the other two?

Jiang Zuiyao began to investigate, trying to find the locks of the two keys, but she didn't find any locks such as boxes or doors.

After searching for a while, I found an anomaly under the chair.

The ground is a stone brick floor, built one by one, tightly packed and seemingly without gaps, but the sound of the nine stone bricks under the chair is hollow.

Jiang Zuiyao simply knelt on the ground and looked carefully, only to find that there was a small keyhole in the gap between the stone bricks, this was because there was a key the size of an ear spoon in her key, at first she was curious about what lock was opened, but now she knows.

It is conceivable that such a small key, such a small keyhole, is extremely difficult to find hidden in the cracks of the stone bricks.

She inserted the key into the keyhole and twisted it slightly, lest she push too hard to break it.

Until I felt the direction of the lock, I twisted it hard to the right, and with a "bang", nine stone bricks were instantly bounced up, overturning the chair that was pressed on it.

Mu Yan outside the door heard the sound, but didn't come in, just asked, "My lord, are you okay?" ”

Jiang Zuiyao replied: "It's okay." ”

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

When the nine stone bricks were opened, it was very heavy, and Jiang Zuiyao had to use a lot of strength to uncover them.

Then, Jiang Zuiyao realized that this was actually a secret door, and under the stone bricks was a long staircase leading to the underground, just like when Zhang Yunian took her underground when she came to the Imperial City Division for the first time that day.

The passage was narrow and thin, and there was only room for her, and it was dark underneath, and there was no light at all.

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

The further down it goes, the darker it becomes, and only a small candlestick can't shine far at all, so that Jiang Zuiyao has to bend his body slightly, and the faint light can only see the road under his feet, fortunately, the steps are neatly built, and it is not difficult to walk.

It can be regarded as coming to the end, Jiang Zuiyao held the candlestick and looked at it, just like last time, there are many houses underground, all locked, each room is independent, and the roads around it are complicated and extend in all directions.

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

This room is facing the steps, so this must be the room.

Put down the box, take out the key, pick out the only key that didn't find the lock, hold the candlestick and shine the copper lock, almost stick it in to see the keyhole, the candle burns a little hot on the forehead, Jiang Zuiyao insisted on comparing the key to the keyhole, you can tell from the shape, it is indeed a match.

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

Jiang Zuiyao hurriedly opened the door, and when she pushed the door, a burst of dust was raised, and she was caught off guard, she quickly raised her hand to fan the flying dust and rubbed her eyes.

It's still black, it's very black, and you can't see the black of your fingers.

With that candlestick, he finally found the candle on the wall, Jiang Zuiyao lit it, and the room lit up in an instant.

This room is not empty.

The room has four sides, the one with the door has nothing, and the remaining three sides are lined with iron bookshelves, which are full of books, and the whole looks like a wall made of books on three sides, and there is a desk in the center of the room, which is all ash.

It seems that this place once belonged to someone, but it was left unused for a long time.

There was no water in this place, and there was no way to clean it, Jiang Zuiyao didn't dislike it, and began to open the books on the shelves, and took one down casually, only to find that it was not a book at all, but a handwritten file, which clearly recorded what Yinfeng Hall had done.

With the words coming into view, Jiang Zuiyao found that they were all some ulterior secrets, when and where the incident happened, who went to investigate the information, what the content of the information was, the records were clear, and each piece of information was written full of seven or eight pages before it was finished.

After reading seven or eight books like this, Jiang Zuiyao found that the handwriting was different, it seems that this is not from the hand of one person, plus the years recorded above, with an interval of several decades, it seems that the second commander of the Imperial City Division has changed several people.

Jiang Zuiyao was deeply attracted by the words on it, and after a while, two or three hours passed, she read about a dozen books, and learned some things that she didn't know, those things, she may not be able to touch in her life, an official wife.

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

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

Jiang Zuiyao asked, "Will you stay here all the time?" ”

Mu Yan replied: "The subordinates are only responsible for guarding during the day, and at night, someone will replace the subordinates, rest assured, there are people guarding here all the time, and it is very safe." ”

"Thank you for your hard work." , Jiang Zuiyao simply said four words, locked the door, and left.
