Obviously, this rope is the key to opening the wall.

But the rope is so heavy, it's an impossible task for me to pull up the whole wall by myself, not to mention that I have to go in...... There must be some mystery in this mechanism that I haven't discovered.

I looked again at the ceiling, where the end of the rope had last disappeared. This mechanism should be the simplest pulley principle, right? Labor-saving by pulleys. So how many pulleys are used for such a heavy wall? How do you feel like it's not enough......

Wait, isn't it...... Did I not find the angle well when I pulled?!

There is indeed this possibility, even if you use more pulleys, if the angle of the pull is too far at the beginning, it will still become very difficult due to the existence of the component force.

I began to try to change positions to pull the rope, but to no avail, the rope was still so heavy, and even a little heavier in some places, until in a few moments my hands were covered with red strangulation marks, and suddenly there was a swollen stinging pain.

If only there were my uncle's medical rubber gloves...... I thought bitterly as I blew into the palm of my hand. There are less than two minutes left before the ten minutes I set, and I have obviously found this step, and I am really unwilling to give up at this time.

At this time, I lowered my head and found something again.

The floor is an old-fashioned stone pavement. This in itself is nothing, but there are a few places that seem to be particularly smooth, and the small edges and corners on them have been polished to a little smooth. I counted five pieces of smooth flooring, one on the left, three on the right, and one in front of the nearest wall.

Each piece of smooth floor is about the size of a footprint. Don't...... Pull a rope, what footwork do you have to pay attention to?

I couldn't help but look at the three pieces on my right hand first. Because it is difficult to see which floor is smooth when you look down from the front, and you can only see the tiny reflections when you look at the side with a light, I specially glued the outline of them roughly with the medical tape from the first aid kit in my bag.

These three pieces are not arranged in a straight line, but two pieces are placed side by side in a triangular shape, parallel to and perpendicular to the right wall. The third block is farther away from the front wall, next to the second block counted from above.

I looked at it for a long time and didn't see anything, so I couldn't help but look at the left-hand piece in frustration. After gluing its outline in the same way, I found that it was the farthest from the front wall, not very close to the wall on my left, and the "footprints" were not parallel to any of the walls.

As for the piece that was clinging to the front wall, I glued the outline and found that it was almost completely level with the front wall. And unlike other "footprints" posted, this one seems to feel empty underneath when you step on it.

I leaned over and carefully touched the floor, and when I reached out and knocked on it, I found that the sound was indeed a bit hollow and dull, and there was some looseness around it. I picked at it, and somehow I lifted the floor.

A small thin piece of iron sits underneath. When I picked it up, there was a small note pressed underneath.

Hurriedly picked up the note and saw that there were only five small brush words on it: "Morality and Thought".

…… What the heck?

I flipped through the front and back repeatedly, and after making sure that there were really only these five words on the paper, I was dumbfounded. The literal meaning of these five words doesn't work here...... What else can you think of? Does it mean that each floor refers to a single word?

…… Does that mean anything......

With a glimmer of hope, he looked at the thin piece of iron in his hand. On the light of the flashlight, at a certain angle, I saw that it really had something written on it: "|\>/".

…… What is it? ……

It's not even a kanji...... How can I read it??

I looked down under the open floor, and there really weren't any other hints?!

It turned out to be really ...... Well...... Well, does a crack count as a hint?

In the white light, the deep crack under the floor looked like a cassette machine. The width...... I subconsciously looked at the small piece of iron in my hand, it seemed to fit very well? …… Hesitating, he reached out and carefully inserted the iron along the crack.

The width was really just right, and the small piece of iron easily "slid in" into it. The crack seemed to be really deep, and it was long before I let go of my hand that I heard a "ding" sound from below, like the sound of iron colliding with each other. Then, as if touching some kind of mechanism, the floor shook slightly, and then suddenly something protruded from the floor.

It was five iron notches, each with a finger-sized hole, all in the smooth floor that I had marked.

It was false to say that I wasn't scared, and my first reaction was to almost throw the tape out of my hand. But before I could come to my senses, the second wave of change began. The small piece of iron seemed to slide off to another track after the first impact, and when it hit something again, the different pieces on the left and right walls suddenly began to bulge and dent in different directions.

I quickly tugged at the rope on the wall to prevent it from wringing into the mechanism as the wall block moved.

Thankfully, after moving to a certain point, the wall blocks stopped again. The walls on the last two sides take on a strange shape.

Then I felt something hit my feet, and I pinched the rope in a daze, and subconsciously shone my flashlight on it, and found that it was actually the small piece of iron that had been thrown in, and it seemed to be ejected after activating all the mechanisms.

I bent down to pick up the little piece of iron, but by chance I was able to read the font on it at the moment—I could just look at it vertically.

“ˉ

ˊ

ˇ

ˋ”

This...... Seems to be the tone in pinyin?

Hey? It seems like it's really those four tones. Why write tones here?

I looked at the five sticky outlines on the ground and the bulging notches, and then at the four tones, and suddenly understood something.

These five notches are in four rows...... Do you represent those four tones?!

So, do the five words on the note mean - to determine the order of the notches according to the tonal order of these five words?

The more I think about it, the more it looks like this. Dao, Virtue, And, Thought, Thought, a total of one tone, two tones and four tones, two three tones, just correspond to the position of these five notches - the first, second, and fourth rows each have a notch, but the third row has two notches.

I stared at the small hole in the notch, that is...... Is this a reminder for me to use this order to string the rope into the notch?

Why don't you give it a try, maybe it will work. I looked at the time, it was more than five minutes, and hurriedly picked up the speed in my hand, pinching the rope and threading it through the notch in order.

The first is the fourth sound, "Dao", which is worn in the fourth row, on the left-hand side...... Then there is "De", and the second sound, the top one on the right-hand side......

But should the next "and" be the lower right, the left or the right? I thought about it, "yǔ" is lower than "xiǎng" in the pinyin table, and it should be the one on the right.

The fourth is "thinking", which is undoubtedly the top ...... The last is "want", of course, the last left right bottom left one.

With all the piercings done, I took a deep breath and pulled it gently.

With the sound of the "crunch" mechanism turning, the wall in front of me was pulled up by me so easily.
