The mechanism in the return door is very different from the ordinary mechanism, the craftsman must have struggled in the design of this aspect of the craftsman, so Su Xin was afraid that he would have to activate the two-sided mechanism when he went out of the door, and now one of the mechanisms in the door has lost its effect, and the falling boulder also trapped the city lord Lan Lan back then, according to Su Xin's thoughts, it is actually a simple truth, some people can enter the door, then the person who enters will definitely know the secret of the mechanism that opens the door.

It is said that the people who can find this place must be very shrewd, just like Su Xin, followed by Shui Xiaoxing and others, and after learning the secret of entering the Huimen Agency, they will definitely try to escape again according to the same method, thinking that this is inevitable, because they already have this memory in their minds.

But at that time, would the people who designed the mechanism be stupid enough not to think of this, according to common sense, it should not be, Su Xin was worried about this, if the mechanism that went out to return to the door needed to activate the boulder mechanism on both sides at the same time, then the boulder that had failed on one side would inevitably become a stumbling block for the other mechanism to be activated, and the moment the mechanism was activated, the room would collapse instantly, so that the bluestone was a little huge, even if it was a small piece falling from above, With Su Xin's small physique alone and the fact that she didn't have a little magic to protect her body, she was afraid that she would face certain death.

Seeing Su Xin circling around Lanlan, but she didn't find anything abnormal at that time, this room was not very big, but Su Xin knew her whereabouts, if you asked Su Xin how to calculate so accurately, the answer was the design of this tomb.

When Su Xin walked around the room, she picked up a small pebble next to Lan Lan, and then she drew a sketch, Su Xin had to figure out the design of the mechanism, so that she could better unlock the secret here, and the mechanism would also surface.

Judging from the sketch, Su Xin clearly drew the two holes that Shui Xiaoxing and others entered, saying that these two holes at that time can also be said to be thieves, after all, the king at that time did have the idea of stealing the best witch book here, but because he couldn't enter the next layer back to the door, he fell short, and it was estimated that he also went elsewhere, although the king was very familiar with this place, but after all, the day city has sunk into the sand, and the day city under the sand is completely different from the former day city, although the location can be determined, but where can be entered everywhere and is buried by Sha Shuo, Everything is an unknown, so it is understandable to have a few more caves here, and perhaps this is one of the reasons why there are mysterious unknown caves in the desert.

They all know that under the two holes are the left and right rooms, and the rooms are very high but a bit like two transit halls, so Su Xin will think that there must be a lot of secrets in these two rooms, but for the furnishings in the house, Su Xin still thinks that it was stolen by people, just like the main hall, there are only some torches in the room, it is impossible to think about it, maybe there are extremely precious things in the house at that time, so they will be stolen, but at present, these things will not be so important to Su Xinran, Su Xin wanted to figure out the general layout of this place, at this time Su Xin continued to draw, under the two halls, Su Xin did vacate the distance of half a room, and then she continued to draw in the vacant place, she took half of the hall and painted a room, then it can be said that the wall between the two halls is the center point of Su Xin's place where the city lord of Lanlan is located.

"Ahh Su Xin couldn't help but gasp, she gradually frowned, and looked at the bluestone above in despair, and then said to herself: "I'm afraid I won't go out, the big stone pressed on the master here should be the mechanism that goes back to the door, if it weren't for the active mechanism, such a huge boulder, I don't think it would fall so easily!" ”

Su Xin knew that he walked in from a similar corridor on the right, so there should be a corridor on the left and right, and the corridor was not long, just a few big characters, but Su Xin was sure that the position at the end of the corridor should correspond to the center of the two halls above, which is the so-called place of the organ, and after the organ is down, Su Xin can see the entrance of the corridor, so as to enter this place like a tomb.

But would a person be so stupid as to make three exits in the middle of the door? Wouldn't that increase the chance of letting the opponent take advantage of the situation, Su Xin shook her little head, and said to herself, "No...... If it's me...... I'm not going to design like that. ”

Now Su Xin has understood a truth, that is, why Lan Lan didn't give up her legs and escape from here, saying that with her witchcraft cultivation, she should be able to escape alive, but it will definitely be miserable, but at least she can save her life, but the reason why Lan Lan didn't do this, it should be what Su Xin thought, the mechanism that went out had fallen due to dust and sand, and the falling boulder was like a steel stone sealing the door, no one could push it, and no one could restore the mechanism, Therefore, Lan Lan was disheartened and wrote a suicide note, and then she was trapped alive in this secret room!

Looking at Su Xin again, her expression was very desperate, with Su Xin's mind, she couldn't come up with a better way, I'm afraid it would be difficult for Shui Xiaoxing and the others to come up with a way, and Shui Xiaoxing and the others were currently waiting for Su Xin to come out and then take them into the back door, so the expectations of Shui Xiaoxing and the others might have to be wiped out.

Su Xin is at risk of being trapped alive, but this incident is true for Su Xin's immortal body, Su Xin will still feel a trace of happiness, but Su Xin doesn't know if she can really die here, and she herself has never tried to go without a drop of water for a few days.

Su Xin's work and rest are very regular, she has been eating and sleeping on time for sixteen years, and she has never stopped, even in the few thoughts of being a ghost, Su Xin will also be like this, maybe Su Xin was born to be everyone's best girl, so life will be so regular.

"I've thought about what it's like to die, but ...... But I never thought it would be ...... now," Su Xin said as he sat quietly on top of a small bluestone brick that had fallen.

If a person thinks of death, then the probability of this person dying will become extraordinarily large, the answer is that despair is at work, and then the various organs of the body will gradually fail, the taste of waiting for death may be bitter after Su Xin herself, she has already thought of death, but Su Xin does not want death to come so quickly, at least to give her a farewell.

"Is that the end of it? Lin Yao...... Maybe we won't see each other again, Xiao...... Hyosung ...... I...... I don't have any scruples now, I can't get out anyway, so what does it matter if I love it or not? Su Xin lowered his head and said this paragraph.

Su Xin is still very strong, she has not shed a single tear from beginning to end, but if Su Xin is replaced by someone else, if it is Lin Yao, even if it is a very bold crescent, when they are also facing the same predicament and going to death, they will definitely leave tears of despair and hatred at this time, but Su Xin really has no hatred for this world at all?

I don't think about it, she hated it when she was a ghost, she was also desperate when she couldn't leave the high school enchantment, when her college dream was shattered, it was a torture that was worse than death, she also wanted to see more of the world, but she didn't want to see the day when Shui Xiaoxing and Lin Yao and others left her, she also wanted to see Lin Yao, and then look at the kid Shui Xiaoxing who made her uneasy, even if it was to give Su Xin another chance to say goodbye, it was always good, But God didn't leave Su Xin with this goodbye!

Su Xin, who did not shed tears, still had a glimmer of hope, she also knew that emotions would change her fate, and there was no food or water source here, even if she was lost, there might be a time when the stream dried up, so it was better to save more physical strength and find the secrets here, so she might as well come by herself.

Speaking of this house, it is extremely weird, it turned out to be a square, it looks a bit like a Rubik's cube, because Su Xin looks at it from the ground, it is divided into nine areas, and each area is a square, but looking at the roof from the perspective of the ground, it is not a square, at least the nine-square grid is not presented in front of Su Xin's eyes.

"It's strange that the roof doesn't show the same nine-square grid as the ground, but why is there only one on the ground, and here is a square, then there must be nine suspended palaces, but why not?"

Su Xin's meaning is that this room is like a Rubik's cube, a square of the Rubik's cube, including the middle, Su Xin thinks that it is the nine palaces, which add up to the twenty-seven palaces, when the appearance of the nine palaces originated from Luoshu, and then there were the nine palaces of the I Ching, and the feng shui of the nine palaces also followed, and the hexagrams and stars were of course essential.

However, the construction of houses is rarely boxy, which can't help but cause Su Xin to wonder, why did the people who built the city at that time design this house like this, in addition to the purpose of protecting the city lord, could this house have other uses?

Su Xin just guessed a random guess, and then guessed something, and heard him say to himself again: "Is it built according to feng shui?" So the location of the falling boulder should belong to the earth according to the five elements? Ay! I'm really ashamed that I'm not good at feng shui, and if it's related to feng shui, I'm afraid I can only solve it here. ”

Taoist knowledge is broad and profound, and Taoist priests are even more difficult to understand, Su Xin can write down the words and sentences in the Mao family's Taoist book, but if she is allowed to calculate, Su Xin will still have a headache, she does not have so much practice to certify her arguments and decisions, just like Su Xin drew a Dao talisman that is exactly the same as Edamame, but Su Xin's heart is not sure to use this Dao talisman, and he doesn't know how powerful this Dao talisman will bring.

The solution to the nine palaces is difficult for Su Xin, so the solution for the twenty-seven palaces is also difficult for Su Xin, it's just a matter of time, but for the solution of the nine palaces of the I Ching, Su Xin is the first two big, so twenty-seven at once, Su Xin is of course unbearable, here not only has the five elements, but also has the five elements to attract and repel each other, just like gold gives birth to water, you can say that one gold gives birth to one water, but what about two gold? Two waters? Ershui must extinguish a fire, this is the so-called attraction and repulsion, of course, this is just according to the five elements, if the hexagram and stars contained in it are added again, I am afraid to solve such a complicated matter, it seems that only one person can do it smoothly, I am afraid it has to be Lin Yao, who is superb in Taoism.
