Happy Halloween

The puzzles on the stone wall can be replaced by filling in numbers.

The white stone bricks can only be filled with numbers from 1 to 8, and each number can only be filled once.

Judging from the pattern on the wall, the numbers that are required to be filled in match the calculation symbols carved on the black bricks.

For this type of problem, you can start with multiplying and dividing numbers.

The prime factors of 8 are 4, 2, 1.

The prime factors of 6 are 3, 2, 1.

The prime factors of 4 are 2, 1.

7、5、3、2、1是质数。

Because each number can only be filled in once, 1 cannot be filled in the grid of the multiplication and division formula, and 4 cannot be used as the product of multiplication.

那么，乘除法两个公式就只能由6与8担任被除数或积。并且，由于2是6与8的公因数，2必然填于左下角的白格中。

假设左上角的白色方格为6，则第一列的数字从上往下依次为6、3、2，最后一行的数字从左到右依次为2、4、8。

The numbers that have not been filled in at this time are: 1, 5, 7.

Let the second number in the first row be X, then the square in the upper right corner is (6-X), and the second number in the last column is [8-(6-X)]=(X+2).

If X=1, (6-X)=5, (X+2)=3, if the condition is not met, discard it.

If X=5, (6-X)=1, (X+2)=7, the conditions are met.

If X=7, (6-X)=-1, (X+2)=9, if the condition is not met, discard it.

再假设左上角的白色方格为8，则第一列的数字从上往下依次为8、4、2，最后一行的数字从左到右依次为2、3、6。

The numbers that have not been filled in at this time are: 1, 5, 7.

Let the second number in the first row be X, then the square in the upper right corner is (8-X), and the second number in the last column is [6-(8-X)]=(X-2).

If X=1, (8-X)=7, (X-2)=-1, if the condition is not met, discard it.

If X=5, (8-X)=3, (X-2)=3, if the condition is not met, discard it.

If X=7, (8-X)=1, (X-2)=5, the conditions are met.

There are two answers, and it is impossible to determine which solution is correct.

At this time, it is necessary to analyze the second sentence on the stone wall.

1, 2, and 3 follow the habit of werewolves from small to large.

What are the habits of werewolves?Do you go crazy after seeing a blood moon?This obviously has no causal connection to the puzzle.

Mu Xuanying thought for a while, and the words written in the "Witcher's Handbook" suddenly appeared in her mind again:

The lone wolf is always looking up at the bright moon which he cannot touch.

Looking up at the bright moon... Observing the moon from the ground...

From the ground, the moon at night rises from the west in the sky and sets in the east.

On the plane, according to the general drawing method, the direction is generally defined as the north, the south, the left, the west, and the east.Using your fingers as a line of sight, you swipe across the air from left to right, which happens to be a half-arc going clockwise.

In other words, the numbers 1, 2, and 3 follow the law of clockwise arrangement from small to large.

Use clockwise to indicate the answers to the puzzles.

假设一：6、5、1、7、8、4、2、3。

假设二：8、7、1、5、6、3、2、4。

Assumption [-] meets all the conditions of the title.

Going around the planetarium, Mu Xuanying carefully tapped the white stone bricks one by one.Every time it is tapped, the white brick is sunken back a little.When the last knock fell, there was a "click" in the ear, and the black brick grid in the center of the stone wall puzzle made a loose sound.

Mu Xuanying's heart skipped a beat, and she rubbed her fingers along the edge of the stone slab for a while, then took out the slate, revealing a secret passage that could allow one person to pass through.

"It seems that it leads directly to a certain room on the third floor." Mo Yu curled his lips. The stairs outside are useless except for escape. Oh, maybe they are just used to place the row of self-confessed statues.

"There is no other way..." Mu Xuanying laughed helplessly.

Mo Yu's gaze slid down to the black stone slab in Mu Xuanying's arms, and suddenly he fixed his gaze and let out a "huh".

"What's wrong?" Mu Xuanying wondered.

"There are words on the back of the slate." Mo Yu said.

Mu Xuanying lowered her head when she heard the words.

"Ah, really."

"Heart of a Wolf"

"Beautiful moon, bright moon.

That curved reflection was the scar in the werewolf Shen Mianfeng's heart that couldn't be erased.

The moon is his redemption, and its pure and holy light bestows upon him supreme peace.

The moon is also his pain, cold and ruthless, he cannot touch it, let alone own it.

Indulging in happiness, indulging in pain, the werewolf exiled himself and became more and more crazy. "

"It's a very sad feeling..." Mu Xuanying couldn't help sighing.

"I can't ask for it." Mo Yu said, he didn't know what he thought of, he rolled his eyes slightly in the dark, and suddenly showed a slightly gloomy expression, "People who are not capable will choose to degenerate themselves, and only those who have enough power can grasp Live what you want."

"..." Mu Xuanying opened her mouth, but did not make any sound.

He disapproved a little in his heart, but he didn't know how to refute Mo Yu's remarks, so he just followed Mo Yu into the secret passage, and then pushed the black brick back to its original position.

Only one person can pass through the narrow secret passage, the air inside is cold and damp, and the sound of water droplets can be heard from somewhere.

The rubbing sound of the soles of the boots on the steps was inaudible. It seemed that the werewolves hadn't approached this area, and the surroundings were very peaceful.

At the end of the stone ladder was also a stone brick, Mo Yu raised his hand to push it, moved the brick away, jumped out of the dark passage, and then stretched out his hand to pull Mu Xuanying.

"here is?"

After he climbed up, he put back the stone bricks, looked left and right, showing a little surprised expression.

The scene in front of them didn't look like they were still in the castle at all.

The ground is paved with black and white brick grids, surrounded by high walls with twists and turns, and light-colored mist floats in the air.

This structure... looks like a maze.They seem to be in a big maze, they don't know how big the edge of the maze is, they only know that they are as small as a grain of grass.

"Is this a room on the third floor? Why is it so big?" He was confused.

"It's just a blindfold." Mo Yu's expression faded, showing a lack of interest.

"Blindfolded?" Mu Xuanying repeated suspiciously.

Mo Yu glanced at him, without further explanation, just said: "The way to get out of the maze is to walk with one hand against the wall, but the safety here is unknown, we don't need to touch the wall all the time, as long as we follow this way of thinking OK."

Seeing that Mu Xuanying understood, Mo Yu took his hand.

"Prevent getting separated," Mo Yu said.

Mu Xuanying smiled and nodded.

A cloud-like mist floats in the air, wandering quietly in the air, even if you hook it with your hand, it doesn't affect its flowing trajectory, and it seems to have no other effect except to block the vision and affect the visible range.But I don't know if it was Mu Xuanying's illusion, he always felt that someone was watching here in the depths of the fog.

The sense of existence is not clear, and the feeling of being spied on is also vague, as if everything is an illusion caused by too tense nerves.

But looking at Mo Yu's side face bathed in the cold light without any emotion, and the inadvertent sharp coldness in his eyes, Mu Xuanying keenly noticed that Mo Yu didn't seem to be indifferent.

There is another person in the maze.

Is it something extremely dangerous like ghouls and werewolves?or something else?

Coldness rushed through his whole body from the soles of his feet, his skin felt a little dense needle prickling, and his fine hair stood up briskly. He hid his nervousness, and focused on observing the surrounding environment as he moved forward.

Unknowingly, his eyes focused on Mo Yu's back.

He felt more and more a sense of déjà vu, this feeling was like a treasure that had been dusted for a long time was gradually wiped off the dust, revealing a beautiful brilliance bit by bit.

It must be a treasure that he cherishes even more.

It became more and more difficult for him to restrain himself from staring at Mo Yu, even though he knew he would be noticed by the other party, but Mo Yu didn't say anything, so he let himself be immersed in this familiar and nostalgic atmosphere.

Everything that happened in the castle along the way, in retrospect, is like a dream.

Maybe it's a nightmare.

Maybe it was a dream too.

A sense of joy similar to lost and found filled his heart. He had no intention of exploring why this strange emotion occurred. He just wanted to slow down time a little bit, and then a little bit slower, as if they could hold hands forever, until the end .

He hurried forward a few steps, walked to Mo Yu's side, and walked side by side with him.

Mo Yu turned his face to the side and glanced at him quietly, without saying anything, turned around and looked forward calmly.

After walking in the maze for a long time, I finally came to the end.But Mu Xuanying looked at the scene in front of her and was taken aback for a moment.

At the exit of the maze, there are four identical doors lined up side by side.

"You only have one chance to open the door."

The soft voice sounded slowly behind itself, without warning, and without any approaching footsteps, but it was already very close to them.

"Who?" Mo Yu turned around and stopped in front of Mu Xuanying, looking around vigilantly.There is nothing around.Suddenly, his body stopped, and he raised his head sharply.

The white smoke seemed to flow substantially, and a pitch-black shadow gradually appeared on the high wall.Mu Xuanying showed a surprised expression until she saw the real appearance of the other party.

"A... black cat?" He was surprised.

That's right, a petite black cat.

Covered in silky and shiny fur, with no variegated color in the pitch black, the cat walked on the top of the wall with silent and graceful steps, flicked its long tail slightly, and sat upright in front of the two of them.

It's really weird, it's just a cat, but it has human-like eyes, rational, calm, sharp, with a slightly peeking interest in it.

It was completely different from the witch's cat I met on the second floor.

That pair of captivating orange pupils stared quietly at the two people on the ground, as if it had seen something that made him feel very interesting, Mu Xuanying found inconceivably that he could see the Mischievous smile.

"Please don't be so nervous, I have no malicious intentions." The black cat said, its tail hanging on the edge of the wall drooped down, and the tip of its tail moved slightly, "You can call me Smoke, even though this is just a greeting The code name used when sending it, but it is by no means taken casually to perfunctory people."

The tone of the smoke has a wonderful and melodious rhythm like singing an opera, and the ending is low and lingering, which makes people's hearts itchy.

It's a pity that there are only two puzzled teenagers standing here.

Mo Yu stared impatiently at the black cat, showing obvious displeasure.

"What do you want to do?" He asked coldly.

The black cat gave a soft "meow" and wagged its tail leisurely.

With the end of the cat meowing, the four doors at the exit of the maze suddenly made a "clicking" sound of the mechanism opening.When they looked back, a groove was removed from the center of the leaves of the four doors, and a sentence was written on each of them.

"There are four doors, behind the three doors are the black and white bears from hell, and behind one door is the room leading to the next puzzle. Only the words on one door leaf are true." Yan said in a relaxed tone, "You only have A chance to open the door. If you guess wrong, you will have to play hide-and-seek with my pet in this maze. Ah, of course, you can also go back to the second floor to play hide-and-seek with that grumpy Mr. Werewolf... It makes no difference anyway, they run at the same speed."

The black cat blinked slightly, its pupils flickering with a playful and sly look.

"How about it, can you confidently identify the only correct one among the messages of these four doors, and find the safe door?"

It seems that if you want to leave this room, you must solve the puzzle of the black cat.

Mu Xuanying approached the gate and checked the words recorded on each door leaf.

〖Gate A: D is connected to the real hell, only B is safe. 〗

〖B door: A is lying, if you want to survive, don't open me and A. 〗

〖C Gate: Open me, I am safe. 〗

〖Ding Men: C is right. 〗

Which door is giving the correct message?Which door leads to the right path?
