(Foreword)

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

Suddenly a memory appeared in my mind, and I suddenly remembered that it was on the bookshelf in the palace. I also saw the battle of the three generals like the 'Heavenly Shadow Book Pavilion'.

"When I was in the palace, I also saw books about the battle of the three generals." It occurred to me that I had an idea.

At the same time, another clue also appeared in my mind:

Wang Ningshuang once mentioned to me that Wang Lao used to go to 'Ningxiu Pavilion' to read. What I am looking at is the 'battle of the three generals'.

"It's a book!! It's a book!! I exclaimed happily.

"Cheng Yin, I'm just proposing to find a few books on the art of war, are you so happy?" Cui Li looked at me inexplicably.

"I know what the old man entrusted to Elder Wang to protect back then!! It's the 'Battle of the Three Generals'" I feel like I've found hope of getting out of here.

"Cheng Yin, you won't tell us that these words are engraved under the 'stone box', you think so, isn't it a bit too simplistic?" Lin Yun didn't believe my conjecture.

"That's right, Wang Lao worked hard to make the 'stone box', but in the end he simply engraved the entrusted things on the 'stone box', which is too trivial?" Cui Li said.

"It's because we didn't think in the position of the old man. The reason why Wang Lao and the head of the Sword Tilting Sect decided to build the 'stone box' was not to keep everyone out of the palace, but to find someone who was destined, so those who broke into the palace by force and stratagem to get the 'stone box' would definitely not be destined, but when they got the 'stone box', it was just an empty 'stone box', and the four heirloom blades without qin, chess, calligraphy and painting could not be opened at all. I paused and continued: "So Wang Lao and the others have come up with a seemingly simple method, that is, to put the guardian in the palace for a long time, and it is a place where everyone who is invited into the palace can see it. ”

"So we were invited into the palace by Wang Lao, and lived in the 'Ningxiu Pavilion', and it was this that you saw that book." Cui Li seemed to understand.

"This idea is so ingenious, only those who are invited into the palace, or who are invited to see themselves, will be brought into the palace by Wang Lao, and placed in a place where they can see the 'Battle of the Three Generals', if they can really open the 'Xuantian Stone Gate'. Naturally, it is easy to think of the 'Battle of the Three Generals' that I once saw. Lin Yun exclaimed.

"What you said is good, but I have a question, if the person who was invited into the palace didn't care about the 'Battle of the Three Generals', even if the 'Xuantian Stone Gate' was opened, wouldn't it be useless? That's too low, isn't it? Zhao Haoyu asked.

"That's it, that's what the old man said about fate, if this person really has a fate with this 'Battle of the Three Generals', how could he not see it? On the other hand, if you don't care about it, you are naturally not the destined person that the old man said. And it's almost unlikely. The destined person will definitely care. I said confidently.

"It's not uncommon to say that you don't see it." Zhao Yuyu said unconvinced.

"In fact, the reason is very simple, just like a computer game, the person who plays the game must be destined to be a talented hero who saves the world. Otherwise, the game can't continue at all, so the people who are destined to be mentioned by the old man are those of us who participate in the 'odd array'. Don't forget, before this 'odd array', what we experienced was the battle of the three generals, and when we saw this book on the shelf, how could we not care? If we really don't see it, then we are just like those who can't pass through the 'odd array', and the destined people here actually refer to those who can pass through the 'odd array'. I explained.

"This ...... It's a really clever design!! Professor Wu couldn't help but admire.

But now there is a new problem in front of us, even if we know that the 'battle of the three generals' left by the old man is very important to the battle situation in Yiling Pass, but it will take a few days to get from the palace, even if I move very fast, but I can't catch up with tomorrow's decisive battle.

"Cheng Yin, then what are you waiting for? Now that we know that it is the 'Battle of the Three Generals', let's hurry up and go to the palace and take it out." Lin Yun urged.

"That's a good word, but ...... It's not a short journey from the palace, and even if we leave now, we may not be able to catch up with tomorrow's decisive battle. I hesitated.

"Then don't fight tomorrow, wouldn't it be nice to change the time?" What Zhao Yuyu said was very light, but the military order is like a mountain, even in this 'virtual world'. If we can't fight a decisive battle tomorrow, it will definitely affect the morale of the whole army, and even if we think of a way, we may not be able to capture Yiling Pass.

"It's a dilemma." Professor Wu fell into deep thought.

"Cheng Yin, have you ever flipped through the book 'Battle of the Three Generals', do you remember the content in it, maybe you can recall it." Cui Li's proposal is a solution.

I closed my eyes and tried to remember the contents of that book, and it was like the 'Battle of the Three Generals' appeared in front of my eyes again.

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 could no longer afford 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 shocks the Quartet...

No matter how hard I try, I can only think of these things. I can't remember anything else......

"No, I can think of so little that I can't analyze it." I said a little depressed.

"It's okay, Cheng Yin, maybe there is another way." Lin Yun's words made me blame myself even more, I held the book in my hand at that time, why didn't I discover the secret in it. I should have paid attention, after all, the words 'battle of the three generals' were enough to make me care, but I actually simply flipped through it and didn't take it too seriously. I finally understood what it means to use a book.

I continued to try to recall, hoping to find at least some clues from some of the sentences, and perhaps these simple words were the key to opening Yiling Pass. The whole tent suddenly became very quiet, and everyone was anxiously waiting for my answer.
