I quickly rummaged through the room, but I couldn't find what I was looking for, but I knew in my heart that if I followed the ghost, it was likely that I had already passed by the key I was looking for, but I didn't recognize it.

"Keykey" I frowned and thought about the shape of the keyhole I had seen before, it was supposed to be a structure of three joints together, and it was not much thicker than my little finger, what was such a thing?

"Prince, think about it, is there anything in your mind that your parents would use to make keys?" I questioned the ghost as I described to him the clue I had gotten, "It should be a slender stick divided into three sections." ”

"I can't think of anything special in the three sections of the stick, what about the thickness?"

"It's about the thickness of a little finger." As I spoke, I subconsciously raised my hand to look at my little thumb, thinking that there might be some differences in the thickness of my fingers between men and women, so I raised my hand and added, "It's probably thicker than my little thumb." ”

"What about the length? How long is it? ”

Length? I frowned, looked at my fingers, and carefully recalled the situation when I inserted my hand into the keyhole, "It should be about the same length as my little finger and so on!" Little finger? ”

Something suddenly occurred to me, and I hurriedly asked the prince, "Prince, did you have any wounds on your hands while you were alive?" Or what happened after you died? ”

"I didn't have any injuries on my hands when I was alive." The ghost's voice was a little puzzled, as if it was a hexagram about why I asked this question, but it still answered me, "I don't know what happened after death, my current ghost body was formed after a period of time after death, and after it was formed, it was trapped in the bones, although it has its own consciousness, but it can't perceive things outside, until you destroy my bones and liberate me, I can use my consciousness to communicate with people, but I still can't perceive things outside." ”

He paused, as if he was afraid that I wouldn't understand, and then explained, "For example, what you just said is about the same length as your little finger, but this length is actually imperceptible, but can only be understood by guessing. ”

In other words, there is something around us that you can't even feel, right? What about the sound? Do you only get information from what I say, or do you perceive what others say? I asked, frowning, the ghost had said something I hadn't expected.

I was still hoping that this ghost would be my eyes and help me guard against some dangerous schemes, but now it seems that it will not be realized.

"I can perceive sounds, all, but not the environment, you can be when I am only ears and no eyes."

I nodded subconsciously, and then remembered that he shouldn't be able to sense my movements, so I said instead, "Well, I see." ”

Remembering what the ghost had just answered me, I had a vague guess as to what the key was.

Walking back to the door of the room, I looked at the skeleton standing on the side of the door and pursed the corners of my lips. I don't know if it's because they feed on people, but the taste of middle-aged men and women is really weird. It's a very complete skeleton, and I can't tell if it's a real human bone or something molded from other materials, but considering the couple's behavior, I think it's probably a real human skeleton.

The whole human skeleton was supported upright by a shelf, one hand hanging by his side, and the other hand was raised in front of his chest, just Bai Sensen's bones, without a trace of flesh and blood, and the eye sockets of the two black holes were very terrifying, and I felt chills when I saw it. Reaching out and touching the human bone, especially the position of the joint, I found that the joint of the bone had been specially treated and glued together, although it would not loosen and fall off, but it could no longer rotate freely. The whole skeleton is not purely used for decoration, but as a hanger. I'm afraid that ordinary people really don't dare to use this hanger

After understanding the composition of the joints of the bones, I had a certain number in my mind, and my guess about the key was immediately confirmed.

With that in mind, my eyes fell on the hand that the skeleton held up on its chest, which was the skeleton's left hand.

When I found the prince's bones before, I examined them carefully, and his bones were not complete, but a part of it was missing, and the missing part was the phalanx of his left little finger. Thinking back to the shape of the keyhole, the thickness and length of the key were similar to a person's little finger, and it was normal for the prince to be a grown man, and his fingers were thicker and longer than mine. In addition, there are two joints on the bone of a little finger, which are precisely divided into three segments, which also fits the shape of the three segments of the keyhole. I'm almost sure the key must be the prince's little finger phalanx!

I squinted slightly, raised my hand to touch the left hand on the skeleton's chest, and pinched the part of its left little finger with my thumb and forefinger. The bones of the skeleton's whole body have been processed and connected, to put it bluntly, its joints are actually dead and inactive, so if my guess is correct, the part of its left little finger must be alive, that is, it can be disassembled!

I pinched the pinky phalanx, and with the other hand held its entire left hand, and the two fingers pulled outward with a slight force—

Really!

My eyes lit up, my heart beat uncontrollably faster, and as I had guessed, I felt only a slight reaction and managed to remove the little finger!

This is the mermaid chain and the key you need to open the door! Didn't run away!

Looking at one of my disassembled finger bones, I compared it to my little finger again, and sure enough, it was a little thicker and longer than my little finger. After confirming it, I carefully received it on my body and put it with Yu Pu's pocket watch. In my left pocket was the necklace taken from the prince's bones, and in my right pocket was Yu Pu's pocket watch and the key to the finger bone I had just found.

When I put in the finger bone, I also touched Yu Pu's pocket watch, now I think about it, this pocket watch was lost in the attic, I don't know if it fell by coincidence or Yu Pu intentionally, I probably checked it, but fortunately, the pocket watch was not damaged. By the way, I glanced at the time above at three and four minutes.

When I heard the merfolk crying for help in the shower, it was supposed to be midnight, which meant that it had only been about three hours since I went to explore the secret room with the wolf fangs, but it felt like a long, long time had passed for me.

Sighing, he put the pocket watch back in his pocket, I knew that now was not the time to be depressed or tired, what I needed to do now was to find my companion as soon as possible, no matter who it was, even if it was Chen Si or Qu Ying, I needed companion.

Leaning on the door and putting my ears to it, I listened carefully for a while, and after making sure that there was no sound outside, I opened a small gap again, and took advantage of the time when the light was tilted out to quickly look at the dim corridor outside, and after making sure that at least there was no danger on the surface, I quickly slipped out the door and closed the door of the room.

The first thing I did after securing the door was to quickly dodge to the side and lean against the side of the staircase, hiding in the shadows of the staircase. I blinked my breath and blinked rapidly, watching the dark hallway in the distance as I waited for my eyes to adjust to the darkness. It wasn't until I felt like I had completely used the darkness that I began to look for companions.

"Prince, I remember you said that there are only four rooms on the second floor, the guest room, your parents' room, your room, and the music room." I looked at the seven doors in front of me, wondering why something was wrong, and frowned to confirm with the ghost.

"Yes, no, it's four rooms. This castle was our temporary residence when construction began, so not too many rooms were built, what's wrong? ”

After hearing the ghost's words, but it was still not that I was misremembering or misunderstood, I communicated with the ghost further, "But now there are seven doors in front of me, which means that there are nine rooms on the second floor, including the guest room and your parents' room. ”

The ghost was silent for a few seconds, as if thinking about the unexpected situation, before saying, "It stands to reason that unless the two rooms of mine and the music room were separated into small rooms, it is impossible to have five more." ”

Partitioned by a large room? My eyes flashed and I looked at the seven doors in front of me. The seven doors are not on one side, there are three on the wall on my left, and four on my right, if they are separated

"Is your room and music room facing each other or on one side?"

"Naturally, it's next to each other, and there is no room on the other side of the staircase."

If the two holidays are next to each other, then these seven doors are definitely not separated!

I looked at the side with the three doors, and suddenly I realized what was wrong with me. It's still the same old problem – space.

This is the same as the situation where we found the stairs in the color TV tower in the uninhabited city and the existence of the secret room, which is a matter of space. It's just that the space was hidden both times, and this time it's more space!

The side of the three doors is the side next to the staircase, and I remember vividly that you can see it from the staircase on the right from the first floor to the second floor, which is about half a meter thick, with the corridor on one side and the empty hall and the top of the staircase on the other. There is no room in just half a meter of walls!

I don't know why three doors without rooms were built there, but this anomaly certainly doesn't bode well. So I gave up on exploring the three doors and turned my attention to the other four.

"Prince, where are your rooms and music rooms located on the right side of the second floor?"
