[PPS: I want to recommend and collect support!! Because it's important, say it twice

There was a blazing burning sensation under his feet, but Su Du didn't have time to pay attention to the bottom for the time being, because the chessboard behind him was already lit up. Sudo turned his head to look at the chessboard under Fiindora and noticed that the bottom row of squares lit up with seven lights, and only the black square in the outermost position 8 was a dull black.

"Seven! It seems that the bottom is the easiest. Su Du whispered to himself, now there are more than 20 seconds left before the impact of the checkerboard squares, Su Du has enough time to climb to the seventh row, but unfortunately there is a light film blocking between the seventh and eighth rows of squares, Su Du tried to climb up, but was stopped by the light film.

Out of boredom, Su Du slipped to the white square of the No. 2 position next to him.

Then, the checkered shock began.

"Boom" The black square in the No. 1 position on Su Du's right almost grazed his arm and rushed out, and this scene suddenly made Su Du sweat with fear.

"It's the opposite!" Su Du was so frightened that he broke out in a cold sweat, and his liver was fluttering and trembling, he grabbed the safety bar in his hand, turned his head and yelled at Fiindora, "You didn't tell me that this safety point is the other way around!" ”

Freindola was not angry, and continued to answer honestly: "That's because Your Excellency didn't ask this question. "Should I say that this girl is terrible honest! For such an important matter, even if I don't ask, shouldn't you squeak in advance? Suduton was speechless, and felt as if he had made a wrong choice.

At this time, the light film above Su Du that prevented him from climbing the seventh line was broken, Su Du had already figured out that there was no specific time limit for this trial, but the demon flame below would slowly rise, and if he didn't climb to the top of the chessboard as soon as possible, even if he wasn't pressed into human meat sauce, he would be roasted into human jerky.

Su Du immediately climbed onto the black square in the second position of the seventh row, and then continued to ask Fiindora, "Is the light of this safe point the opposite?" ”

Fiindola replied, "This is a forbidden matter, and you can not answer it below." ”

Fiindola didn't answer yes or no, which made Sudo suspicious, and then turned his gaze to carefully observe the light of the safe spot on the opposite chessboard. This time, Su Du felt that the time for the seventh line of squares to appear safely lit up seemed to be a few seconds less than when they were in the eighth row. Don't doubt Sudo's feelings, based on his experience in various games, this kind of trial has always been more and more difficult, and the reduction in time for judgment is also expected.

There are only 6 safety points lit up in the seventh row, and there are still 7 in the eighth row, and further up they belong to the blockade zone, and Sudu cannot observe.

[If this safe point is decreasing according to the difference sequence of 7, 6, 5, 4, 3, 2, 1, then when you reach the second row, there is only 1 safe point left, and the first row doesn't even have it, damn it, are they kidding me?] Su Du calculated in his heart, and suddenly felt that something was wrong, but he had already boarded the thief ship, so he could only continue the trial.

The safety point that lit up was the remaining squares in the seventh row except for the outer squares 6 and 7, and Su Du had already guessed in his heart, so he quickly transferred to the white squares in the first position of the seventh row. Sure enough, the squares of this impact were the squares of the seventh row No. 2 and No. 3 and the eighth row No. 1 on the left side of Sudu.

After the collision, Sudo continued to move forward, this time the unlit squares in the sixth row of the board at the feet of Fiendora were 3, 4, and 6; The next fifth row is the 2, 5, 7, and 8 squares.

At the same time, as Su Du came to the fifth line, the time for the safety to light up was getting later and later, and the time provided for Su Du to transfer the position was less than 20 seconds. Sudu believes that there is a pattern to the location of the safe point on the chessboard, but so far, he has not found this pattern. Now, Su Du thinks that if he continues to move forward, a little bad luck in the fourth row of squares will be the end of turning into human meat sauce, so he still stays in the fifth row, trying to find the pattern of the appearance of safe points while the demon flame has not yet burned.

Because of Sudu's stay, this time the squares in the fifth row of the impact became 3, 5, 6, and 8, and in the next impact it changed to 1, 3, 4, and 6, and the next time it became 1, 2, 4, and 7, and in the fourth collision, it returned to the 2, 5, 7, and 8 positions at the beginning. Su Du also noticed that the squares in the sixth, seventh, and eighth rows below, the squares that collided with them, also returned to the original position at this time.

This discovery also made Su Du confirm his speculation, and sure enough, this safety point, ah no, it should be said that the appearance of the collision point is regular.

But the first thing to talk about is the relationship between the chessboards, the two chessboards are actually exactly the same, but because they are placed opposite each other with the front, the 8th position of the eighth row of the chessboard under the feet of Freindora corresponds to the 8th row of the 8th position on Carla's side.

And this calculation is not to calculate the safety point, but to calculate the collision square, take the initial collision as an example, the chessboard on the side of Freindora, the collision square is the eighth row 8, the seventh row 6, 7, the sixth row 3, 4, 6, the fifth row 2, 5, 7, 8, after excluding these squares, the rest is the safety point.

The rule is also very simple, with the eighth row of the 8th position as the initial positioning point, the initial positioning point of the seventh row advances 1 square in the 7th position, and at the same time, the adjacent square in front of the initial positioning point of the seventh row collides with the square in the 6th position, which is temporarily named as the new point A; The initial anchor point of the sixth row advances 1 square in the 6th position again, the new point A in the seventh row is adjacent to the initial anchor point 1 square in the 4th position, and then the adjacent square in front of the new point B appears in the 3rd position; The initial anchor point of the fifth row continues to advance 1 square in the 5th position, the new point A advances 2 squares in the 2nd position, the new point B advances 1 square in the 8th position with the new point A as the positioning point, and the adjacent square in front of the new point B appears the new point C in the 7th position.

It's not a complicated reasoning, and with enough time, many people can deduce the rules, but not many people can figure it out in such a short period of time.

After this calculation, the collision squares in the fourth row are 2, 3, 4, 5, and 8, which are converted to the board on Kara's side, which is 1, 4, 5, 6, and 7; The third row after that is the 2, 3, 4, 5, 6, and 7 positions; The second row is the 1, 2, 3, 4, 5, 6, and 7 positions.

Sudu believed his speculation and went directly to the No. 3 position in the fourth row, and almost at the same time as he just grasped the safety bar, the impact began, as Sudu speculated, the No. 2, 3, and 8 positions in the fourth row were all safety points. Then Sudu moved forward quickly, quickly moved to the No. 8 position in the third row, dodged the new shock, and then came to the No. 8 position in the second row without the slightest hesitation.

This time there was only 5 seconds, and almost as soon as Su Du put his hand on the safety bar, the impact began. The collision grid brushed the soles of Su Du's shoes, and once again frightened Su Du into a cold sweat. At this time, Su Du suddenly realized the biggest problem:

The squares in the first row, according to his assumption, were no longer safe.

[Could it be ......] Su Du suddenly thought of a possibility, and before he had time to hesitate, he quickly reached out and grabbed the safety bar of the first row of squares, but at this moment, the first row of squares had already begun to impact.

The squares with a thick sense of substance slammed forward with Sudu, and on the opposite side, there were hard squares that also hit at high speed.

ps: Try to see if you like this simple reasoning game. If you think it's okay, there will be this kind of intelligence duel in the future, of course, in other ways.

PPS: When I was writing this chapter, the author drew two chess boards on the left and right sides to make up for my lack of spatial imagination. It seems that the author is not qualified to use the dragoon system.
