It's getting late, it's not dawn

It is said that people's psychology changes with the situation, that's it, life has to go on, if you encourage me and I encourage you, maybe life will become a little different.

Hua Xinyu took a sneak look at Lin Qing, and found that Lin Qing was also looking at her. She felt that the atmosphere was a bit weird, so she quickly returned to the topic and asked, "Great talent, you have read a lot of books, so the above four sentences What do you mean?"

Lin Qing didn't think about anything else anymore, and now the only thing to do is to go out. He looked at the words on the wall and pondered for a long time before he said: "The most important of these four sentences should be the last sentence'needle turns ugly Can survive'."

Lin Qing looked up at the white cloth hanging above, and then said: "That is to say, we have to adjust the coronal needle of the corona to the position of Choushi, so that the way out will appear, and we will have a chance of survival. It should be the meaning of 'turning the needle into ugly can survive' written on it."

Lin Qing pointed to the corpses hanging on his finger, and he guessed that the key to finding out should be on these corpses.

Hua Xinyu didn't dare to raise her head to look up, because the ragged corpse of a skeleton was really frightening, she lowered her head and asked, "Then how can I get the crown needle to the ugly position?"

Lin Qing pondered and said: "This... I don't know, but there should be a mechanism, let's find the mechanism to mobilize the crown needle."

Speaking of which, Lin Qing began to search again. After searching for a long time, the two of them found that the mechanism for mobilizing the crown needles was right next to the inscriptions, which made it easy for them to find.

Because the mechanism is designed to be on the same plane as the wall of the abyss, unlike the pits where the lettering is written.

Moreover, the moss on it is almost the same as the growth in other places, covering the position of the organ, so they couldn't find it at all at first, until they peeled away the moss around the four lines of characters, they found that the organ was next to the lettering.

Looking at the organ on the Yuanbi, the two heaved a sigh of relief, and finally found it!

The mechanism is a square of Gongzi grid, which is divided into 25 pieces on average, five by five. There are words on each square, but they don't know the words on the square.

However, numbers were engraved on the side of the mechanism, and each square has a corresponding number. Although the engraving is very small and the notch is not very deep, it is still clear. From the handwriting, it can be seen that it is still the same person. engraved.

The outermost numbers, that is, the numbers of the four side lengths of the square are 12345-54321-12345-54321, connected end to end, with two corners being 1 and two corners being 5.

Then there are nine inner blocks, two diagonal lines, one is 1, the other is 5, and the intersection is 2.

The remaining squares are all zero.

as follows:

1 2 3 4 5

2 1 0 5 4

3 0 2 0 3

4 5 0 1 2

5 4 3 2 1

Lin Qing and Hua Xinyu looked at this string of numbers, and then at the grid mechanism, feeling distressed in their hearts, especially Hua Xinyu, who is not very good at math, and this puzzle game really gave her a special headache.

But headaches are headaches, and you still have to pay some brain cells if you want to go out.

The two just stared at the numbers so hard, their brains running rapidly, wanting to see what was going on with this mechanism, and occasionally staring at each other, but helplessly, they still found nothing.

There is no way to start with this, Hua Xinyu complained again: "The reminder to go out was given but it seems that it was not given, how do we solve this?"

Lin Qing didn't answer Hua Xinyu's words, but still focused on looking at the numbers. Lin Qing always felt that the arrangement of these numbers was very familiar, as if he had seen them somewhere, but after thinking about it, he couldn't remember what it was. Where have I seen it.

"You can survive by turning a needle into an ugly one," Lin Qing murmured, and just after he finished speaking, he recalled an incident when he was a child. He looked at the numbers on the wall of the abyss again, and finally understood why they were familiar. It turned out that he really Having seen these numbers, he tried hard to recall, and he was sure that this was the math game number board that his uncle taught him to play when he was a child.

These numbers look like a headache, but the calculation method of this number plate is actually very simple, that is, an operation about addition, subtraction, multiplication and division.

His uncle once told him that this counting game is a commonly used arithmetic game somewhere in China.

Could it be that Uncle is talking about Changsheng Village, or that the people who carved these words were from the place that Uncle mentioned, or these words were carved by Uncle, but these handwritings are not from Uncle’s notes, so they should not be engraved by him .

Thinking of this, Lin Qing felt a little sad. His uncle had been missing for so long and he couldn't find him now. He misses every family member very much now. Of course, this is talking about the home he had when he was a child. The relatives of the family that maintained it.

However, he also knows that his uncle is not an ordinary person. How can an ordinary person have such a good skill, how can he have such a powerful martial arts, even if he has such a good skill now, in front of his uncle, he dare not say that his skill is good Well, what he has learned in this body is only superficially what his uncle taught him.

And his uncle was not brought up by his grandfather Manyue since he was a child, but was rescued by his grandfather when he was 20 years old, and then he lived with them all the time. Of course, Lin Qing hadn't been adopted by Manyue at that time , he was adopted after his uncle.

Originally, his grandfather didn't allow his uncle to live here, because the family was in a difficult situation, and his grandfather also spent all the family's money before begging a barefoot doctor to save his uncle, because his uncle said at the time that it was considered a Don't go to the hospital to die.

After he recovered from his injury, his uncle saw that his grandfather had spent all his money to save him. In order to repay his kindness, he often went out to earn money to subsidize the family. After a long time, Man Yue also accepted the fact that his uncle became a part of the family.

He didn't understand it before, but now that he has experienced so much, he has come to understand it. Even if his uncle is injured, he will not go to the hospital. All signs indicate that his uncle is not an ordinary person.

After thinking about it for a while, Lin Qing wanted to get back to business, and remembered the rules of this counting game.

Simple addition, subtraction, multiplication and division rules.

This number plate uses the combination of numbers and shapes to calculate.

The way to press the plus sign is to press the number on the middle line of the square horizontally first, and then press the number on the middle line of the square vertically, and the track is "+".

The way to press the minus sign is to press the number on the middle line of the square horizontally, and the track is "-".

The method of multiplying is to press the numbers on the two diagonals of the square, and its track is "x".

The method of pressing the division sign is to press the number on the center line of the horizontal square, and then press the number on the midpoint of the upper and lower side lengths, and the track is "÷".

The rules of this game are: give the first to the last, and count the tail from the first; if it is smooth, it is irreversible; when counting, the smallest is the first, and the smallest is the largest. First, repeat, until the mantissa comes out, according to the rule, first press the number, then press the point, continue to press the four arithmetic operations, and then press the number.

That is to say, this game gives the first and last numbers, use the first number to calculate the last number, and can only be calculated in the order of addition, subtraction, multiplication and division, and the order cannot be reversed. When calculating, you must first calculate from the smallest number. If the result is still not reached, then take the smallest calculation, and then proceed to the next level of calculation. If it still cannot be calculated, take the calculated result as the first number, and repeat the above rules until the result is calculated.

According to the rule, first press the number, then press the most central number, then press addition, subtraction, multiplication and division, and finally press the next number.

Lin Qing looked at the top of his head. At this time, the crown needle was pointing to Shen Shi, that is, the first number was Shen, and Shen was nine, and they wanted to turn the crown needle into ugly, that is, the tail was ugly, and ugly was two. The first and last counts are nine and two, that is to use nine to calculate two according to the above requirements.

According to the algorithm his uncle taught him in his memory, Lin Qing quickly came up with the pressing method, and then imitated pressing on the engraved number, and after confirming that it was correct, he pressed the pressing method on the palace mechanism. .

As soon as the button was pressed, an abnormality appeared below the abyss. Dots of green light began to slowly appear below, and the dots of green light gradually increased, and finally turned into clusters of green light.

Green light slowly surged upwards, illuminating the abyss in a faint green, like the Hall of Hell, this green light is much brighter than Lin Qing's watch, because there are too many spots of green light, they have clustered into clusters at this moment.

Not long after the green light rose, bursts of rapid buzzing came up from under the abyss. The sound was very strong like the sound of a windmill spinning rapidly.

The green light slowly approached Lin Qing and the others. After the green light got closer and closer to them, Lin Qing realized that the rising speed of the green light was not slow, but the speed of the green light was a bit slow when it came from a very deep place. .

The green light got closer and faster, and the buzzing sound became louder and louder.

"not good!"

Lin Qing exclaimed, and quickly pulled Hua Xinyu close to the wall of the abyss, then squatted down quickly, trying to lower her body and keep close to the wall of the abyss. When they squatted down, the green light continued to rise from them at an extremely fast speed.

After these green lights passed by them, the ears of the two were filled with persistent humming, as if the whole world had no other sounds except humming.

It wasn't until the green light continued to rise for a while that the buzzing sound gradually died down from their ears.

The two looked up and found that the green light was all attached to the hanging corpses and the ropes hanging from the corpses, and instantly turned into a crown needle emitting green light.

Then something strange happened.

A slight buzzing sound came down from above, and then the two saw the green light driving the hanging corpses and ropes to slowly turn, and the top had turned into a huge crown needle emitting green light. The crown needle slowly changes from Shen time to Chou time.

At the moment when the crown needle turned to the ugly time, a "click" sounded, and this "click" seemed to be a starting signal. With its sound, a series of sounds followed.

The abyss wall slowly changed, and they quickly stepped back a few steps to observe.

A space on the wall of the abyss was slowly recessed, moss was scattered, and a regular octagonal hole appeared on the wall of the abyss.

As the movement gradually became smaller, the two people slowly approached the entrance of the cave. Unexpectedly, as soon as they approached the entrance of the cave, a large group of dark things appeared at the entrance of the cave. Dodge along the wall of the abyss to avoid those dark things from attacking them.

They didn't look up at the group of black things until after the group of black things flew out, and saw the group of black things swarming towards the green light, the green light was swallowed up in an instant, and the entire abyss Immediately it became dark again.

It was just dark for a while, and there was a change again. There were bursts of screams from above, and then there were clusters of fire lights, and those fire lights fell one after another. It smelled like it was burnt.
