The reason why Thor was able to tell at a glance that he was on a certain level of the tower at the moment was because of the sky outside the window.

This room is surrounded by brick and stone walls, with only a wooden window frame on the front wall, in which there are no lattices or crystal windows, so the transparent view can be seen far at a glance.

Outside the window, there was a vast expanse of blue stretching into the distance, occasionally dotted with some drifting white clouds.

In mainland Salvinia, there is no sky, or even if you look up, there is only a dark canopy of the sky.

People can only rely on the descriptions in those old books to fantasize about what was once blue. As a result, Thor has never been interested in the scenery personally, but at this moment, looking at the clear and untouched sky outside, he still has to sigh beautifully.

Approaching the window, as his vision widened, Thor expected to see the horizon in the distance, but he didn't.

The only thing that catches your eye is still the boundless blue, and sometimes there is a warm wind, rushing in from the window frame and hitting your face.

Thor didn't give up, and the whole person stepped on the blue-gray masonry to climb the windowsill, adjusting his gaze to the maximum perspective from above and down. He had thought that he would be able to see the land around the foot of the tower, but it was still only blue.

This shocked Thor a little, and he couldn't see the horizon, and there were roughly two possibilities.

One is that the tower I am on is very high, so high that it is indescribably high, which is contrary to architecture. The other is that the land supporting the foot of the tower may be just a small island, obscured by the poor vision caused by the height of the tower.

Eventually, Thor gave up on the idea of building terrain in his head, which was clearly out of the realm of logic.

And even if you rack your brains to figure out where this tower is, whether it is a magic tower, a lighthouse, or something else, it won't help you on your journey to the top in the end.

In fact, if you think about it, you came to this place after falling asleep, maybe it was just an absurd dream of yourself.

It was obviously daylight at this time, and the ample light made the environment of the entire tower floor clear.

Looking closer, you can see withered vines clinging to the surface of the exterior wall, and some of them have even climbed near the window.

The whole environment has a sense of ancient desolation, as if no one has set foot here for hundreds of thousands of years.

The room he was in had only three walls, the left and right sides of the wall were at right angles behind him, and the front wall was a large semi-arc with a small window on the half-curved wall.

Again, back to the path you have now chosen.

At the moment, there are wooden stairs up and down in the room, and then there is an old wooden door on each side of the wall, which means that if you want to start moving, you have four options: up, down, left, right, and left.

Thor reckoned that if he chose a random door from both sides and opened it in the same direction, he would probably end up looping the tower and returning to the original room, provided that there were no strange changes in the terrain.

Of course, everything was just speculation, and Thor began to take steps to verify it.

The bare feet stepped on the old wooden floor, and the sound of decaying explosions was amplified in the silence.

Thor walked to the wooden door on the right wall, the whole wooden door was not high, the square bottom was domed, and there were no locks on the door, which was not much different from the wooden doors he was common to in reality.

The only thing that's interesting is that the door can be pushed both outwards and inwards.

Constantly opening the door in one direction, Thor soon circled the tower.

In the end, I concluded that my judgment was basically right.

The tower has a total of nine rooms, or is divided into nine rooms of various sizes by the masonry walls of the 'well' shape, and the eight rooms around it are exactly in a circle, and then there is another room in the center of the tower.

In terms of environment, except for the one in the center of the tower, each of the other eight rooms has a small window that can be overlooked. Some of these rooms have two wooden doors, some have three, and the one in the center of the tower has four doors.

This is supposed to be a vertical labyrinth built with the tower as the main body, and the way out should be in a certain direction between the top and bottom, and the doors that can be opened on the perimeter walls are just to increase the complexity of the labyrinth.

Saul breathed a sigh of relief after coming to his conclusion, because this maze might be a little easier than he thought. The way out is nothing more than choosing between up or down, that is to say, if you choose a direction randomly, you have half the probability of going right.

The only thing that worries me is that once you make the wrong choice, it takes twice as long to correct it.

For example, starting from the tower where Thor is located, assuming that the exit of the maze is on a certain level below, the distance between the two floors is ten.

But if Thor chooses to go up, and after walking the distance of ten, he feels that he is wrong or wants to change direction, he must turn back and walk out of the distance of ten plus ten to solve the mystery.

That is, for every wrong step, you will end up with double punishment.

Thinking back to the time when he was promoted to the third order, he spent more than a month in the underwater maze.

Now that you are promoted to the fourth order, even if you choose the right direction, it is estimated that it will take two or three months, even if it is three months.

A better result, if you choose the right direction once, you can return to reality after three months. The worse result, if the direction is wrong, is three months plus six months double the time to go back and correct the mistake, and you can return to reality after nine months.

Of course, this is just my own optimistic estimate, and maybe this maze is more complicated.

With a rough guess, Thor didn't hesitate anymore and began to climb the entire tower upwards.

There is no specific reason for choosing the upward direction, most people may choose to go down, because the closer you are to the psychological aspect of the people at the bottom of the tower, it may be easier to do so, after all, people live on land. Although I yearn for the sky, it is still scary to climb into the sky.

Another reason is that Thor remembered the first vast labyrinth, and common sense would have thought that the exit of the labyrinth was at the edge of the labyrinth, but in fact the final exit was somewhere in the center of the labyrinth.

If you insist on finding the border, you may still be trapped in the first maze today and haven't come out.

So Saul thinks that these labyrinths may be out of the logic of common sense, and the exit of this tower may be in the sky.

Of course, it may also be that all of Thor's speculations are meaningless, and everything is just a coincidence. Anyway, in the final analysis, you always have to choose a direction, since there is half a chance of success up and down, so go up with your heart.

As his footsteps shifted and time passed silently, Thor gradually entered the state.

This so-called state of entry does not mean that the mental state has improved, but that the whole person has entered numbness and forgot the time.

For the first few days, Thor was on the upswing and enjoying the quietness in his heart.

He can calm down and think about some questions about life and the future.

Later, I began to fear what if I couldn't get out again, what if the whole tower suddenly collapsed.

Later, the madness and irritability passed, and they returned to their original calmness or numbness. The whole person is almost too lazy to think about anything, he will only go up, layer after layer, forgetting where he is and why he is climbing.

Somewhat contrary to Saul's initial judgment, he didn't just go up all the time.

He had to go through all nine rooms of each tower, first around the eight rooms, and then open the middle one to take a look, and he had to make sure that the exit was not hidden in one of them.

And in the process of climbing, there are still some troubles from time to time, such as often encountering a door that cannot be opened, and cannot be broken with force, or when you want to go up, you suddenly find that the wooden staircase is broken.

So Thor could only go around and around, looking for an exit that might appear in the next moment, or never find it.

Time is no longer able to calculate how much time has passed, maybe a month or two, maybe longer.

In order to slow down the rate at which his will is being drained, Thor has to start recalling. Think about anyone you met in your life, where you said what you did, and what you did.

So the soul may be sitting in a tree in Newtown, enjoying the night view with Chletty, or lying on the edge of a wall with Hughes, peeking at the slender lines of a bathing nun.

Later, he couldn't think about it anymore, and he could only fall back into the reality in front of him.

Count the steps of the wooden staircase of each tower and talk about getting by.

Thor had fantasized more than once that it would be nice if a monster suddenly appeared in a room. Then you can kill him yourself, or just have a fight, and just talk a few days.

But no.

The tower of the sky seemed to have no end, it was so quiet and extended.

After climbing for a long, long time, Thor suddenly broke out in a cold sweat, and he found that he still wanted to be simple.

Since there is no end to the upward pathway, there is no chance of correcting the mistake at all.

Whenever you want to turn back, the voice in your heart will tell you that you are not far away, and you will be there one level higher. And when you go up a level, another voice will tell you that you are going in the wrong direction, and that one day you will have to go back to the old place and pay a greater price.

This mental torture was initially only vague and tiny. Then it is amplified with the flow of time and begins to be everywhere, tearing at your nerves all the time.

In addition to this, there is an unchanging view of the surroundings, including the room, including the weather. In the tower, it is always daytime from the window, there is no night, only blue sky and white clouds.

And Saul's mood has also changed from initial appreciation, to later ignorance, and now as long as he sees the blue sky, he will be inexplicably irritable.

will not be hungry, sleepy, and stop, this kind of silent and silent consumption is obviously the most terrible, and people who are not strong enough in their hearts will probably choose to end in place long ago.

Thor suspected that he had climbed above the sky, and what was above the sky? That's good, it's obviously a blessing to have a new question that has no answer, or to be able to think about it.

I don't know what day it was, after counting the steps of the wooden staircase under his feet, Thor habitually moved to the right to open the wooden door on the wall, but subconsciously raised his hand and felt empty.

No, I have long been familiar with the various spacing of each layer, and I have never missed it, why......

Suddenly look up.

Thor stood there and shuddered for a moment, as he found himself in an aisle.
