Happy Halloween

"Fill in the square..."

Mu Xuanying sat on the ground with her sleeves hanging down, her fingers resting on the mirror-smooth brick surface, her brows were tightly frowned, her face solemn.

Each square has two possibilities of black and white, either black or white.According to the clues given by the puzzle, in a total of 400 squares, there are 176 black squares and 224 white squares.All he needs to do is find the correct location of those 176 black squares.

"The way to solve the problem... Start with the longest row of black boxes, for example, the 8th row counting from bottom to top. The clue given by the question is (2,12). , and the 12 black cells cannot be arranged on the top to the left, at least 8 cells need to be vacated for 12 black cells and 3 white cell. From this, we can simulate 2 possible situations in row 1... "

Among these 21 possibilities, the results of the 9th to 15th columns are determined to be black, and the gray parts of the other columns are doubtful. Therefore, the 8 white cells in the 9th row, 15th to 7th columns can be directly turned into black .

In the same way, use the digital information given by each row and column to first flip the determined black box over.Then, use the previously filled squares as new clues to eliminate the possibility of unqualified rows and columns with fewer black cells, and narrow down the selection range step by step until the original pattern is restored.

click.click.click.

The stone slab was flipped over and over again, Mo Yu stood on the spot, and could see Mu Xuanying's quiet silhouette with her head slightly lowered, her hair hanging down, her eyelashes lowered, casting a feather-like shadow.

The moth flapped its thin wings and quietly stopped on the edge of the jack-o-lantern, and the enlarged shadow stretched and flapped on his shoulder.The young man shrouded in dim light exudes a quiet and peaceful atmosphere, and his eyes are filled with soft and confident bright colors.

From an angle that Mu Xuanying couldn't see, Mo Yu's eyes were so red that they almost turned black, and the light in his eyes moved secretly, with a strange and treacherous brilliance quietly flowing.

In his field of vision, the originally white stone bricks glowed faintly with blood, and these blood bricks were being turned over to the side of the black bricks one by one, forming an incomparably vivid figure together with them.

"It's done!" Mu Xuanying said happily after flipping the last black box to the ground.

Solving the puzzle, the shape obtained is——

A cat playing with a ball of yarn.

Hearing the "click" sound from the door, Mu Xuanying immediately breathed a sigh of relief, feeling relieved.

In an inconspicuous place under the original door lock, a small partition suddenly moved away, exposing another keyhole.

According to the witch's message next to the floor tile, it is obvious that this is the real door lock.

The keyhole on the top is just a cover-up.Or rather, it was a trap.

"This design is really cunning!" Mu Xuanying exclaimed.

Mo Yu gave a "hmm", looked at him, and stretched out his hand.

Mu Xuanying held Mo Yu's hand without hesitation, stood up, and looked back at the restored floor tile pattern.

"This, it seems... a cat playing with a ball of yarn?" He hesitated slightly, guessing uncertainly, "It's quite cute."

"It's just a bad joke." Mo Yu pouted as he said.It seems that he is dismissive of the hobby of witches.

Mu Xuanying smiled.

It seems that the rumors are true, the witch really likes cats very much.

But speaking of it... the place is really heavily guarded.

The nine-life cat guarding the door, the puzzles in front of the door, and the key to unlock the door at the end. Before entering the witch's room, they have gone through several tests.If he and Mo Yu hadn't been reminded by the ghoul, he and Mo Yu walked up the stairs to the second floor, and it would have been impossible to find this place no matter what.

There are many traps, and as long as they make a mistake in the process, they may be injured or die.

He has to be more cautious, more cautious... Mu Xuanying quietly glanced at Mo Yu and made up her mind.

Brother Mo Yu must not be allowed to fall into a dangerous situation.

The Witch's House is a delicate and beautiful house.Hanging gauze curtains, the sweet orange nectar mixed with the rich aroma of roses permeates the air, and the smell of benzoin seems to linger in the nose.The slightly swaying rocking chair is covered with a layer of soft white fox fur, as if someone was lying on it leisurely just a moment ago.

There are dolls in gorgeous dresses everywhere in the room. The brocade is silky and bright, and the intricate and delicate lace is piled up on the cuffs and skirts.These dress dolls are made to be extremely beautiful, some are blond-haired and blue-eyed and cute, some are silver-haired and red-eyed are ice-cold, some are black-haired and blue-eyed are elegant and refined, they sit or stand, raising their eyes and frowning, lifelike.

"It's amazing, just like a real person..."

Mu Xuanying has seen many dolls. The girls in the town always have such a toy in their homes. Some are placed in the most conspicuous position in the house, and some are held in their arms all day long.But even the most expensive shops in town don't have such exquisite dolls, and I'm afraid even the craftsmen who boast of their superb skills can't do anything about it.

Among them, the most solemn, luxurious and ingenious one——

Queen doll.

In the center of the field of vision facing the gate, the queen is wearing a crown, holding a life-length scepter inlaid with huge gemstones, and a crinoline-style dress with as many as [-] layers supports the graceful curvature of a birdcage.The long dress is made of bright and smooth taffeta, with clusters of lace and a long skirt that trails to the ground.She stood in a dignified posture and was extremely glamorous. A curtain of argentine red hung down, making her white and tender skin seem to be glowing lightly, and her pair of sparkling eyes were captivating and soft to the bone.

A miniature white Persian cat was lying on the queen's feet, with golden and silver demon eyes, and the little felt was very realistic.

If there were two girls standing here, they might have already lingered on these beautiful dolls and couldn't put them down.

But Mo Yu glanced at the whole room, but remained indifferent, almost writing the word indifference on his face.

Suddenly, a black hardcover book came into his field of vision, Mo Yu's expression changed slightly, and he walked to the bookcase.

This book looked ordinary, with no words on the spine or cover, but in his eyes, a flame-shaped pattern appeared on the cover.Opening the book, the first thing that catches the eye is a delicate girl with a red hood, gold foil, silver bells, and a Persian cat, all of which are brightly colored pictures.

Turn to the second page and it says:

"Witch Notes"

"Everyone has a ghost in their heart.

Fierce evil spirits, cunning evil spirits, they constantly struggle with the good side of human nature, tempting people to go down the road of degeneration.

It grows day by day, becomes stronger day by day, and the older the human being is, the more bewitched it is.

I am the witch Mirigul, a witch who signed a contract with the God of Death and belongs to the dark world.

People justly say that I am evil, but my cat tells me that the evil spirits in their hearts have already swallowed up human nature, and they are several times bigger than ghouls!

Hee hee hee.

Human beings are a bunch of selfish, self-deceiving liars. "

Don't trust anyone, even a witch who hates humans?

Mu Xuanying leaned over to Mo Yu's side. He thought he was doing it without anyone noticing, and quietly tiptoed to peek at the notebook in the young man's hand, with a pensive expression on his face.

So she has so many dolls in her room, would she rather live alone and be with cats than be close to other people?

"Did you find anything?" Mo Yu asked without looking back.

"Huh?" Got caught?When did brother Mo Yu notice it?Mu Xuanying was taken aback, and said nervously, "Uh, I found out... I found out that there are so many dolls here!"

Is not this nonsensical?He wanted to cry for a moment.

Mo Yu turned around and glanced at him, and said lightly "Oh".

In order to prove that she didn't get nothing, Mu Xuanying hurriedly told her discovery: "I counted, and there are a total of 66 dolls in this room."

"……so what?"

An envelope tied with a red ribbon was handed to Mo Yu.

Mu Xuanying looked at him with a smile, tilted her head, and her long ponytail slid down her shoulders.

"Found it in front of the doll, I guess it's a new puzzle," he said.

Mo Yu took the envelope silently.

The bow is undone, the ribbon falls to the feet, and the opened letter exudes a fresh sweet scent of laurel.

The faint but distinct fragrance of fragrant leaves diffused into the air, and the two stood side by side, looking at the crumpled letter paper together.

The bronze lamp shines brightly, and the orange-red candlelight shines brighter through the thin crystal.The reflection of the queen doll holding the scepter was reflected on the ground, and suddenly moved.

"I am the queen of the puppet kingdom."

"I am the queen of the puppet kingdom."

"I have the most beautiful face and the most luxurious dress."

"I have the most beautiful face and the most expensive dress."

Mu Xuanying was slightly taken aback, and turned around to look.There was clearly no third person in the room, but the position where the queen doll stood changed unconsciously.She stood outside the curtain, facing the direction where he and Mo Yu were standing!

The sweet female voice drifted to her ears, telling her heart, which was also written on the letter paper.

The Doll Kingdom has 66 dolls, the most beautiful one is the queen, and the rest are her subjects.

"However, no matter how excellent a doll is, it still needs countless jade and jewelry decorations to bring out my nobility and beauty...

"Master Witch bestowed 66 precious gems on the doll kingdom, each doll has one.

"The queen has the right to change the gem distribution plan, but the change plan must be decided by the votes of the subjects, the minority obeys the majority, and I cannot vote myself.

"My subjects are selfish. If she gets more gems, she will agree with my decision; if she gets fewer gems, she will oppose my decision; if her gems remain the same , she will not vote.

"I am a great queen, and I deserve to get the most gems. Those ugly dolls don't need gem decorations at all, and their faces can't bring out the brilliance of those gems at all.

"Can you help me realize my wish? As a reward, I will give you my favorite rose."
