Cold ice can't break the water, and dead wood can meet spring again.

I looked at the pieces scattered on the ground, and while it all seemed to have a lot to do with chess, it didn't rule out that there could be other ways to solve the puzzle. In many cases, the so-called truth is often just a blind spot in front of our eyes.

"Xia Cheng, do you think it's possible that the puzzle we have in front of us is not just as simple as a chess array?" I picked up a chess piece from the ground with the word "Jin" engraved on it.

"Cheng Yin, I also think this is very strange, aren't these chess pieces, but trying to give us some hints?" Xia Cheng carefully looked at the chessboard in front of him and continued: "This chessboard is just a simple nine-palace layout, and it is not a chessboard, there must be some connection in it that we don't know. ”

"I think you're just thinking too complicated. Isn't this just a chess-related puzzle? Cui Li picked up a chess character engraved with the word "handsome" from the ground and put it back on the nine-square grid.

"I think the key to this puzzle is still on this chess piece." Cui Li said and moved the "handsome" chess piece on the nine-square grid repeatedly, as if looking for the answer to the question.

But the mechanism in front of him did not react in the slightest, and Cui Li did not give up.

"Cui Li, don't try, if it is a puzzle that can be solved by just moving the 'handsome' chess, it will not appear in the puzzle designed by Mr. Ouyang Yu." I said.

"Yes. Of all the puzzles we've encountered since the Lost Garden, the only thing we have encountered since we thought of the complex problems was oversimplification, and it seems that this time will definitely be no exception. I always felt that the puzzle in front of me was not just a chess game. If it's just a game of chess, then at least the opponent's chess pieces will appear on the chessboard, but you see that there are no other chess pieces on this chessboard except for a 'handsome' chess, just imagine if there are only your own chess pieces on your chessboard, and the opponent does not even have a chess piece, is this still a duel? Zhao Yuyu said.

"You've said so much, but no one has made the problem clear, and it's not right or that, so what should we do? If we can't activate this mechanism, there will be no hope of defeating Lu Xun's army. It can be seen that Cui Li is very emotional now.

"Cui Li is right, no matter what, we should try as much as possible, even if we can't succeed in the end, then at least it will rule out a wrong option, just like we are in physics research, before the subject research, none of us know what the real answer is, only repeated testing and research, eliminating one impossibility after another, will finally find the real answer." Professor Wu's tone was like he was explaining the course to us.

Professor Wu also has some truth in what he said, rather than thinking about the answer here, it is better to eliminate one impossible after another as Cui Li did.

"Professor Wu is right, all of us now apply our ideas on this chessboard, maybe we really happen to discover some mystery." I agreed.

"You see, this chessboard is made up of nine squares, but strangely enough, there is only one piece on it. Do you think you can solve this strange array by putting chess pieces on all nine spaces? Li Ruina said as she picked up eight chess pieces at random and placed them on the chessboard. Of course, the answer is conceivable, and it doesn't work.

"It doesn't seem to be useful, maybe it's not as simple as filling it with chess pieces." Arthur said helplessly.

Suddenly, Zhao Yuyu had a flash of inspiration and exclaimed, "I know, I know!" Li Ruina is right, as long as you put chess pieces on the nine-square grid, you can activate this strange array. However, it is not placed randomly, but it needs to have some fixed chess pieces. ”

"Fixed pawns? So what are the other eight pieces? Cui Li didn't seem to believe what Zhao Yuyu said.

"Quite simply, there are 32 chess pieces in the chess we are familiar with, but the pendulum of chess is not placed anywhere at will like in Go, but is placed at the beginning of the game according to the rules of chess and then played." When Zhao Yuyu was excited, he was interrupted by Cui Li: "We all understand what you said, isn't it like flying chess, you have to put the chess pieces in the base camp at the beginning, but what is the connection between this and what you said?"

"Of course, that's where the key lies in unlocking the game. On the same straight line placed with this 'handsome' chess, there are two 'shi', two 'elephants', two 'horses' and two 'rooks', and if you count the 'handsome' in the middle, there are no more or no less, exactly nine chess pieces. Zhao Yuyu's words were amazing.

That's right, there are certain rules for the placement of chess, and the chess pieces around 'Shuai' chess add up exactly nine pieces to correspond to the nine-square grid in front of you.

"That's right, classmate Zhao, you're right, these chess pieces add up to exactly nine, let's hurry up and find the other eight scattered chess pieces among the scattered chess pieces on the ground." Professor Wu said happily.

It seems that all the problems are solved in front of us, and the door to victory is slowly opening to us.

After Professor Wu finished speaking, we searched for the eight chess pieces on the ground. Thanks to everyone's efforts, we soon found all eight chess pieces.

Zhao Yuyu put all the eight chess pieces on top of the nine-square grid, looking forward to this mechanism being activated by us in this way. However, victory did not seem to come so easily, and the mechanism in front of him still did not react. It seems that this method is not the final answer.

"How so? It's impossible, it should be these eight chess pieces, what's wrong? Zhao Yuyu looked very confused.

"Do you think that although we have found these eight chess pieces, there is also a certain pattern in the placement of these eight chess pieces?" Arthur suggested.

"That's right, it must be like this, if the eight chess pieces we found are not wrong, then the reason why we didn't activate the mechanism must be the placement of the chess pieces. But what is the correct order of placement? What is it? Zhao Yuyu fell into deep thought again.

I looked carefully at the chessboard in front of me, was it really as Li Ruina and Zhao Xiaoyu guessed, as long as the corresponding chess pieces were placed, the mechanism in front of me could be activated? My mind was always full of questions.
