The scene of thousands of ghost wolves lying on the ground shocked everyone, but what was even more surprising was that the wolves in the outer circle crawled on the ground and actually made way of a passage!

Shen Mo looked along the passage, his eyes shrunk, and a group of naked strong young men followed by Quiet, slowly walking towards the silent people.

"You're finally willing to show up." Shen Mo looked at Quiet and said, in the first two games, he has been planning behind the scenes, and Jiang Xiaochuan is the pioneer, but this time it was surprising that Quiet was the first to appear.

"Since it's a war game, then of course I'll come forward, Jiang Xiaochuan has more important things to do, then, you have to use this person against my army of the Ghost Clan?" Quiet has always had a smile on the corner of her mouth, as if she had a winning expression.

"No, you've always been talking about conditions, why don't you let me play a game with you first, and then play what you call a 'war game'?" Silent and slow.

Although there were thousands of ghosts and wolves around, and dozens of ghost clan masters were present, they were silent and fearless!

"Oh? Why should I listen to you, what capital do you have to negotiate with me? "Quiet's eyes are full of disdain, the first two defeats are all due to silence being too cunning and keen, but this last one, he will win!

Shen Sanshi stood behind Shen Mo and compressed his voice into a line: "These people in front of me are not to be afraid, but I faintly feel that at least three auras that are not weaker than mine are locking us in the dark. ”

Shen Mo put his hands behind his back and quietly gestured to 'don't be impatient', and then said to Quiet: "You don't want to defeat me with your wisdom? Are you sure? ”

Quietly narrowed his eyes, his eyes revealed a trace of resentment, and he said in a deep voice: "What game?" ”

Seeing that Jing Jing didn't plan to invite himself up the mountain, he pondered silently for a moment and said, "Then let's play Sudoku." ”

"Sudoku?" Quietly fell into thought and slowly spoke: "What's so fun about this, if there is only one solution, you and I can calculate the whole picture." ”

Sudoku, a game of logical reasoning through numbers, a total of 81 grids, divided into nine areas, each area needs to fill in the numbers from 1 to 9 respectively, and each number can not be repeated horizontally, a game with infinite possibilities.

Finally, each area is 1-9, and the horizontal and vertical are 1-9, which is to solve the puzzle in its entirety.

"Of course, it's not fun to play like this, so we add two rules on top of that, the first one, on the 99 squares, we start writing down the numbers one by one until the blank sheet is full.

If the person who wrote the wrong word, erase the mistake and it will be put on hold for two rounds! ”

"Hmph, isn't this just a little change in the rules of Sudoku?" Quietly listened to the silent words and laughed.

"Within the nine-square grid, we have to complete the second rule: 'three consecutive lines', that is, in a small nine-square grid, the last person to fill in the number is to occupy the nine-square grid, and the last to occupy the nine-square grid is up and down, left and right, obliquely, and the person who can connect the three nine-square grids into a line is the winner." Silence said this rule after a moment's thought.

Quiet frowned, since this is the case, then the person who writes the number first has a complete advantage, you once, I once, and after eight times, the ninth time can occupy a nine-square grid.

This kind of idiotic rule, could it be silently figured up?

"Yes, but I need to write it first." Quiet instantly understood the loopholes in the rules and spoke first.

"I'm fine, but what if I win?" Silent smiled and narrowed his eyes and asked.

You win?

Are you kidding!

The Sudoku rules combined with the one-line rules form an irreversible unfair game!

There are a total of 81 grids in the nine-square grid, and the person who writes first is completely superior, how can you win!

"What if you lose?" The corners of Quiet's mouth hooked up a sneer, and he asked rhetorically.

"Whatever you want, but if I win, I need to meet Li Tiecheng, I want to make sure he doesn't die, and then come to play war games with you." Silently said his conditions, thinking that even if he arrived in the land of ghosts, he would not let himself see him, so it was better to use this as a winning condition.

Quietly listening, he slowly closed his eyes and turned around and said, "Okay, then let's go." After turning around, Quiet couldn't help but smile, and said secretly in his heart: Very good, silent, this is your own death, I will leave you a lifelong memory!

He had already begun to fantasize about how to torture and kill Shen Mo, begging for mercy in pain towards Shen Mo.

Stepping on the snow, the ghost wolves burrowed into the ground one after another, and the silent people followed Tranquility to the territory of the Ghost Sealing Clan, which was a complex of buildings standing on the top of the mountain.

The entire Goddess Langma Peak is as if it has been flattened by a sword, and at this moment the cap has been built into a quaint small city.

Walking into the city, the streets are a little deserted, because there is no guide, and the silence does not know what is going on, it may be that the peak is cold, so they are all in the house to avoid the cold.

With the quiet along the street into a palace-like building, the palace is all made of bluestone blocks, now full of snow, like an ice palace, silently from a distance, I saw a golden statue standing in front of the palace door.

It's the shape of Quiet in a fur coat and standing on crutches and looking ahead!

But after a long time, the statue was also covered with a layer of floating snow.

Walking into the main hall, Jiang Xiaochuan greeted him, and seemed to be asking quietly with his eyes: What is the situation, how did you come to get it back!

Quietly recounted everything to him, Jiang Xiaochuan also smiled and said, "That's right, I'll go and prepare some paper and pens for you." ”

Everything is in place, and the white paper is a square of one meter by one meter, and 9 rows and 9 columns are outlined evenly on it, with a total of 81 grids.

The positions of the three columns in each of the three rows are accentuated and thickened to form nine areas, each with nine grids.

Quietly stood in front of the paper with a red pen, and silently held a blue pen opposite Quiet.

And Jiang Xiaochuan and several masters of the Ghost Sealing Clan stood behind Quietly.

Shen Sanshi was also standing behind Shen Mo, and they were also very curious about how Shen Mo would win this game.

The game of Sudoku is ancient, Shen Sanshi and Chu Ming don't understand it, and they haven't touched the milk bottle, only Bai Youbai knows some.

"Since you go first, then you write down the first number first." Said with a silent smile.

Quietly glared at him, looking at Jiugongge and falling into deep thought.

Time passed minute by minute, quiet but no intention of writing at all, and everyone suddenly felt a little confused.

"Why hasn't he written yet?" The few people in the bottle looked quiet and didn't move, and asked Bai Youbai next to them.

Bai Youbai pondered: "Although this is a Sudoku game, but because of the three lines, this is more like playing chess, 81 grids, just like the 81 points of the chessboard, every step must be accurately planned, every step must not be mistaken, not only to calculate the number of each grid in the whole game, but also to ensure that he can occupy a small area, but the first seventeen numbers should not be so difficult, so he should be planning something." ”

Shen Mo turned back very easily: "What Bai Youbai said is also right and not right, he is thinking, where to write the number, what number to write, now the 81 grids are empty, then that means there are infinite possibilities, but as I write more and more numbers with him, in the end there is only one number law that can fill the whole picture, so he will consider, how to write, can not only cause me trouble, but also cannot let me predict what the number on a certain line is." ”

"Huh? Is this game so difficult? Shen Sanshi's eyes widened, although he didn't understand a little, but it was so difficult to listen to.

At this moment, the silence moved, and he held the pen and gently sketched a delicate number on the seventh column of the first row of the grid: 4!

Shen Mo didn't think about it after seeing it, so he wrote the same one in the third column of the sixth row: 4.

"Huh? Sister Bai, since there can be no duplicate numbers in the same column and area of the same peers, it is completely possible to write the same number in different areas with the numbers written quietly. ”

Bai Youbai glanced at the milk bottle and said: "Then it's not a puzzle game, it's a game of brainless numbers, they are digging holes for each other, and through the numbers they write, they are embarrassed for each other." ”

Quiet frowned and glanced at Shen Mo when she saw it, and then quickly picked up her pen and wrote the same letter in the fourth column of the third line: 4!

Shen Mo didn't put down his pen quickly this time, but mentioned it and looked at Jiugongge and fell into deep thought.

"Ahh Then why do they just write a number! The bottle looked at the silent pause, and asked again with some worry in his heart, according to his understanding, the more a letter appears, the easier this game will be to solve, so why did the great god fall into thinking instead?

Bai Youbai thought slightly: "Neither of them wants to write down other numbers, to deal with more thinking routes, the more a number is written, then the rest of the number positions will be relatively fixed in a range, and the algorithm will be less and less, but there will be countless possibilities for other grids, in addition to 4, there will be countless combinations of 12356789, for example, you see ...... here." ”

Bai Youbai stretched out his hand and pointed to a few small areas without the letter 4 and said: "All the grid numbers are fixed into some kind of law because of these three 4s, which means that the solutions have become countless in an instant. ”

Silently looked at the white paper, and finally wrote a 4 again in the fifth column of the seventh row on the white paper, and then looked at the quiet.

Bai Youbai is right, although it seems easy, but in fact, it is necessary to calculate well, what number can be written in each grid.

This requires a lot of computing time, and the purpose of playing this game is to use your own strengths, quiet has quick wit, quick thinking, but you are good at thinking slowly, and thinking farther than quiet.

Now it's very simple to fill in the numbers at this stage, as long as there is no 4 in the horizontal and vertical, and there is no 4 in the small area, you can fill it in, but each time you fill in one, the game is simpler.

Quietly looked at the 4 written silently and began to calculate it in his heart, and then Jiang Xiaochuan lightly touched Quiet's back and whispered: "Don't be fooled, you can't write four." ”

Quiet for a moment, then looked at Shen Mo and his eyes rolled wildly, indeed, you can't write, the more you write this Sudoku whole, the more obvious it will be, after you calculate the numbers in each row and column, you have to cause trouble for the other party, this is the most important thing.

After a quiet momentary thought, write the letters in the first column of the first row: 1.

Looking at the quiet pen, each number from 1 to 9 instantly came to mind, and then his brows furrowed, and he fell into deep thought again.

"What's the situation with this great god, why did it stop again?" The bottle was a little anxious, he didn't understand Sudoku, but he understood that the great god was a little hesitant at the moment.

"Shhh Bai Youbai whispered.

"What, is this something that the human brain can do? Is the great god an advantage or a disadvantage now? ”

"Although this game seems to have a certain advantage for the person who writes first, it is not easy to say, and it can only be seen who gives whom the problem is greater, because as the number is written more, there are some grids that can be deduced by relying on the rules of Sudoku."

As the two discussed, Shen Mo finally put pen to paper, and he chose not to be another number, it was still 4!

Fourth row, ninth column, letter: 4!

Quiet raised his head suddenly, a trace of consternation flashed in his eyes, how could he still write 4?

You must know that there are a total of 81 grids, and each number can only be written 9 times, and now the two have written 5 4s, which means that there are only 4 4 in the unknown grid!

And the more you write, the more obvious the position of 4 becomes!

Quiet gaze scanned back and forth on the nine-square grid, staring, the corners of the mouth showed a smile, do you like to write 4 no, that's good!

Quietly lifted the pen and landed in the sixth column of the fifth row, looked at Shen Mo and smiled: "I'm sending you a 4!" ”

The bottle was stunned!

How to write another 4!

"Sister Bai, what's going on, isn't it that the more you write, the less you write, the more difficult it is to write, how can he still write this number!"

Bai Youbai pointed to a few 4s on the white paper: "This 4 is not written quietly, but silently forced to write quietly, you look at all the positions of 4, just silently put down the grid directly ruled out the reason why a whole line can not appear 4, and the other two 4s written by Shen Mo directly excluded 7 spaces in the middle area of the nine-square grid, and the 4 written quietly in the second area is also excluding a space in the middle area, so calculated, the position of the middle area can write 4, and there is only this place, this is the elimination method!" ”

Quietly glanced at Bai Youbai with interest: "There is really a person who can play Sudoku, you are right, this number is a clear number, that is, the number position that is clearly pointed out by the number 4 we wrote before, also known as 'irreversible fixed number'!" ”

Quietly smug a smile, he looked at Shen Mo again and said, "You want to leave this position as a space to think, but I'm sorry, I won't leave this space for you!" ”

"What are you so proud of, when you see that the great god will write down the next 4, you won't have a place to cry." The bottle pointed at the quiet and shouted.

Jing Ze sneered: "If you have the ability, you can let him write one and read it." ”

"Ahem." Jiang Xiaochuan coughed at the right time, turned around quietly, and saw Jiang Xiaochuan pointing to the bottom of the white paper.

Quietly looked at her fingers, and was suddenly shocked, and almost shouted a 'Nima'.

"That's right, I can still write 4, not because I can, but I think farther than you, you only saw a bright area when I wrote 4 last time, but!" Speaking silently, his tone suddenly became heavier, he picked up the pen and wrote down the number in the eighth row and eighth column, and continued: "I set two 4s in one stroke!" Since you said I couldn't do it, then you can find the next 4 there! ”

4！

The number stung the quiet, the authorities were confused, the bystanders were clear, Jiang Xiaochuan also frowned, he suddenly found that Shen Mo was more powerful than he thought, he was far-sighted, and deliberately omitted a 4 for Quiet to write, and when his arm was withdrawn, it blocked Quiet's sight, so that he couldn't see the position of the 4, so that he could write another 4, causing psychological pressure on Quiet.

But will Quiet easily admit that she might as well be silent?
