Yan Nanshang's answer was very natural, but she didn't know that her answer ruthlessly overturned all Luo Yang's previous speculations.

Although the sound of books falling is not very loud, it still attracts the attention of some people in such a quiet place.

Xiao Nan obviously discovered Luo Yang's abnormality, and asked in a low voice, "What's the matter, what problem do you remember?" ”

Luo Yang didn't answer Xiao Nan, he organized the language for a moment and then asked Xiang Yan Nanshang: "Is it possible, the answer can only be the only one?" ”

Yan Nanshang did not disappoint him this time: "In fact, no one can fully explain the deep principle of Sudoku, but your question is also a problem that many people have been studying all their lives. Now the official conclusion is that a minimum of 17 numbers is needed to ensure a unique answer! ”

Luo Yang looked at the notebook in his hand and suddenly sighed lightly: "I think I understand the true meaning of those numbers." Xiao Nan! From the first floor to the third floor, it seems that there is only one way to the next floor! This means that we need to fix a unique answer. And the official should and must meet this condition. Otherwise, even if we get the answer, we will get the data out of the box because it's not the only answer. If we get the real answer by eliminating the wrong answers, there is definitely not enough time! The reason why we get so many numbers in just two layers is not because the questions are simple, but because we have to get enough numbers above 17 to get the only answer. That's what the maze is really about! ”

Speaking of which, Luo Yang has come to the final conclusion: "This question is very simple, and we can easily get the answer, but the key point of the problem is that we may not live to that time!! ”

Xiao Nan rubbed it, and just when he was about to stand up, he suddenly remembered something, and he only rubbed half of it.

She whispered and said eagerly, "Then what are you waiting for, let's hurry up and find more clues!" ”

Luo Yang shook his head: "You forgot that there is another key issue??? How the hell did we get to the second floor! ”

Yan Nanshang didn't rush to answer after hearing this question, she thought for a while before replying: "This problem can find the law through calculus, and I can be responsible for calculus." You'll have to find the pattern yourself. ”

Luo Yang nodded, then turned to Xiao Nan and said, "Don't worry! Even though we may not have the only answer, we have super cheats. Maybe you can brute force it through cheats. If we can find the truth to move on to the next level, then it's almost like solving the puzzle! ”

Xiao Nan looked at Yan Nanshang, who was working hard, and Luo Yang, who was holding a piece of paper and studying it carefully, and nodded boredly with his left hand supporting his head.

She knew that this morning might be over.

Although Yan Nanshang likes liberal arts, her talent is added to science.

Although the speed of cracking was getting slower and slower, she still handed over the answers one by one.

Luo Yang stared at the five answers and examined them carefully, each with a different number at the entrance of the passage. When he entered the state, he also took out a pen and paper and began to calculate, trying to find a pattern.

At first, Xiao Nan could still endure to watch the two calculate, but sitting for a few hours had reached her limit.

"If we really can't find a pattern, we can't memorize all these answers, and try them one by one? It's better than wasting time! ”

Luo Yang didn't answer her, he looked at Yan Nan's clothes.

Yan Nanshang shook his head and handed over the sixth answer by the way.

As you can see, it's uncertain how many answers there are to Sudoku. What if we don't have the right answer in the back! ”

Xiao Nan took the answer for him and handed it over.

On the other hand, you can't prove that the answer is in it, right? Then the swallow's actions are invalid! I've come up with a compromise. We memorized the answers and then went into the game to try them out one by one, and Swallow continued to crack them here. In this way, there is no delay. ”

Luo Yang thought for a moment and replied, "That's an idea!" ”

Seeing that Luo Yang actually agreed with him, Xiao Nan changed his previous malaise.

She excitedly added, "Then without further ado, you quickly memorize the answers." Aren't you good at pulling lists? Let's test these answers one by one in a list format. ”

"Order..."

Luo Yang took the answers handed over by Xiao Nan, and while looking at them, he was planning in his mind which order to record them.

At this moment of dual-mindedness, he was suddenly stunned after a few instinctive glances.

"Order, order..."

Xiao Nan and Yan Nanshang found that Luo Yang had entered a neurotic state at this time, which often indicates a major discovery, and they held their little hands very tacitly and quietly watched Luo Yang go crazy.

Luo Yang didn't stay in a daze for a long time, he pointed to the latest answer and pointed to the first fork in the road between the two: "Maybe I'm thinking too much, or maybe the answer is that simple." When I saw this answer, I realized it at first glance. It's simply the simplest matter of order! Now, the number corresponding to the first layer to the second layer is 1, the number corresponding to the second layer is 2, and so on, will this be the principle of entering the next layer? ”

The two looked at the position pointed by Luo Yang, and the first number on the first layer was indeed 1, and the sixth number on the second layer was exactly 2, if this was really a coincidence, it would be too coincidental!

"That is, we only need to remember the number of ascending numbers in the remaining layers to predict all the remaining exits in advance?"

Luo Yang nodded vigorously: "Not only that! Conversely, this answer is exactly the same as the first three entrances we explored earlier, so could it be the correct answer? ”

The three of them glanced at each other, quickly got up and ran to their dormitory.

Luo Yang quickly recited while holding the paper, and at the same time quickly applied for leave on the desk. By the time he returned to the dormitory and entered the game, Xiao Nan was already waiting by his side.

When the two of them went offline, they were at the fork in the road from the second floor to the third floor.

Luo Yang thought about the answer and found that the entrance to the third floor happened to be the sixth fork.

In other words, as long as they continue to move forward from the fork in the road in front of them, as long as they can't see the gold coins at the end, it means that they have directly entered the fourth layer!

Luo Yang calmed down, grabbed Xiao Nan's hand and strode forward!

Xiao Nan anxiously reminded: "You haven't marked it yet!" ”

Luo Yang smiled: "No need, if we guess correctly, we can go all the way with the plug-in." If you guess wrong, the mark doesn't seem to make much sense! ”
