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

(Text)

Once again, I was lost in thought, and everyone was silent. No matter how hard we tried, we couldn't find the piece we needed, so much so that I began to wonder if this piece really existed in this 'odd array', could it just be used to play us?

But Mr. Ouyang Yu is not such a boring person, the 'odd array' he designed must have some kind of intention, and there will never be such a boring setting, but at this time, we have not found the key point, and the real answer has been ignored by us.

I looked at Arthur who was constantly searching, and although she didn't know if she could find the piece I was talking about, she didn't give up, she trusted my judgment so much, and I questioned myself again and again.

"Cheng Yin, I roughly estimated that there should be thousands of these scattered chess pieces, and we have almost searched for them all, but there is still no chess piece engraved with the word 'Dong' as you mentioned. Is there a chance that there won't be two pieces together to make up the piece you need? Although Zhao Haoyu's speculation is that there are some possibilities, such as the text can be disassembled or reassembled, and each edge of the structure can be replaced with each other to form a new text, the structure of 'Dong' is quite simple, and there is no single character that can be composed at all.

Zhao Yuyu went on to explain: "Just like the crossword puzzle we played when we were young, when we needed a word for 'dew' but we didn't have a ready-made word, we would combine 'rain' and 'road' to achieve this word. Do you think we are in this situation now, and we need a combination of two chess pieces to achieve the effect of the two chess pieces that Cheng Yin said? ”

"Although what you said is right, what Cheng Yin needs is the 'East' chess piece, which doesn't seem to be able to be combined with the other two chess pieces, right?" Professor Wu said with a skeptical expression.

"That is, how is it possible to combine this with the other two words?" Cui Li patted his head and thought hard, but he didn't seem to have any good ideas.

"Yes, there are indeed two words that make up this word." Xia Cheng said categorically.

"Yes, there are two words, but they are now in my hands." Zhao Yuyu held two chess pieces in her hands, and I saw her walk quickly in front of me, spread out the two chess pieces in her hand and said, "These two chess pieces are 'seven' and 'small'." ”

"How do you make up the words 'seven' and 'small'?" Cui Li asked puzzled.

"You're stupid, can't you just structure up and down?" Zhang said coldly, with a hint of sarcasm in his tone.

I looked at the two chess pieces in Zhao Yuyu's hand, and although I didn't know if it was possible, I found all the chess pieces, at least giving me a chance to realize my conjecture. I picked up the two chess pieces in Zhao Yuyu's hand and walked towards the nine-square grid.

"Cheng Yin, can you tell us what your thoughts are now? What exactly is the function of 'east', 'south', 'west' and 'north'? You always say that Mr. Ouyang Yu has told us the answer from the beginning, but what is this answer? Cui Li desperately wanted to know the answer to this puzzle.

"Cui Li, don't worry, I'll explain all this now. When we entered the security setting of this AEF research center, there were three problems in front of us, the first was the mystery of the wall of light, the second was the battle of the three generals, and the third was the 'strange array' we were in now. We have always mistakenly thought that these three problems have no connection, but in fact, these three problems are connected to each other, and together they form one of the three 'strange arrays' carefully designed by Mr. Ouyang Yu. The first puzzle of the wall of light tells us the framework of this 'strange array', and the second battle of the three generals runs through all the main lines, which is the key to solving the puzzle in front of us. I said slowly.

"The battle of the three generals is the key to solving this puzzle? But I don't see any connection between the two. Cui Li looked at me with a look of no understanding.

I took out the book on the battle of the three generals and spread it out in front of everyone and said, "As I just said, Mr. Ouyang Yu has already told us the answer, and this answer is exactly what is written in this book. "Before I finished speaking, Cui Li had already read the text on the battle of the three generals:

"Once upon a time, there was a general who led a large army to press in, passing through a city, and after a few days of fighting, the defenders of the city were no longer able to continue to defend the city. In fact, he could have fled the city, but he didn't, and still led the remnants of his old army to stand on the tower. Its heroic spirit is terrifying..."

Cui Li finished reading the above words in one breath, but he still looked inexplicable.

"Cheng Yin, I admit that I'm not smart, you better tell me what the hell is going on."

In fact, the answer is in the last sentence of the whole paragraph: its heroic spirit shocks the Quartet...

The 'their' in this sentence refers to the general, that is, the 'handsome' chess in my hand, and the answer to the 'shock Quartet' is probably self-evident, right? ”

"'Shock the Quartet'! No wonder, no wonder you need to look for the four chess pieces of 'East', 'South', 'West' and 'North', that's what it means! It seems that this time it can't be wrong! ”

Zhao Miyu's face showed the joy of success.

"I didn't expect it to be so laborious to start a mechanism, but at least it shows that our efforts for so long are worth it." Cui Li said with emotion.

"Alright, now is the moment for us to solve this puzzle." I stood in front of the nine-square grid, put the 'handsome' chess piece in the middle of the nine-square grid, and then placed the chess pieces in my hand one by one on the nine-square grid in the order of going up, north, down, south, left, west, right, east.

When I put the last chess piece that was supposed to be engraved with the word 'Dong', I realized that the position on the right was exactly the upper and lower structure, which seemed to be in line with Zhao Yuyu's conjecture.

We put the two chess pieces behind the nine-square grid, and we were full of hope that the mechanism in front of us would be opened, but as time passed, the result we expected did not appear in front of us.

I seem to feel that time has stood still in front of us, are we still wrong? I couldn't believe what was happening in front of me.
