Although he complained about Cotton, Han Nuowei still fought hard and began to solve the problem. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The gold medal on the left is divided into four parts, the circle in the middle is one section, and the rest of the space is divided into the other three parts. They are arranged in the order of top left, top right, bottom and center, and the gold medal numbers in the first row are "4, 3, 6, 1".

The gold medal numbers in the second row are "1, 7, 4, 1".

The gold numbers in the third row are "1, 2, 3, 3".

The gold medal numbers in the fourth row are "4, 2, 3", with empty center.

The gold medal numbers in the fifth row are 3 on the top left, empty on the top right, 1 on the bottom, and 9 on the middle.

If the X is used to represent the missing number, it is:

4361，1741，1233，423X，3X19。

Han Nuowei frowned and thought for a while, what is the pattern of these numbers?

The first gold medal can be understood as 43 divided by 6, and the remainder is 1;

The second gold medal is 17 divided by 4, and the remainder is 1;

The third gold medal is 12 divided by 3, and the remainder is ...... 0?Han Nuowei stared at the 3 in the middle of the third gold medal and shook his head. There is no 0 in the gem particles available to him, and obviously, this rule is not right.

Could it be that the three numbers on the outside are added up, and the number in the middle is the biggest factor besides oneself?

Han Nuowei immediately dismissed the idea.

Han Nuowei pondered for a while, even the linear equation was used, but the calculation was not an integer, he was very irritable, and casually picked up the outermost 6 of the gem grains and put it into the groove in the middle of the fourth gold medal.

A violent shaking startled him. The metal fence at the edge of the stairs had risen a little higher, already waist-level with him. At the same time, the steps have also risen by more than ten centimeters, and now, Han Nuowei's line of sight has reached the position of the gold medal in the first row.

This thing is like a little cage.

Thinking of this, Han Nuowei shivered all over his body, if he couldn't solve the puzzle in a limited number of times, he would be raised to the ceiling and then trapped alive in a cage?

Han Nuowei turned his head, looked at the chessboard square, and sighed. There was no turning back, and he didn't dare to waste any more times, so he had to take out the 6 just now, put it back in the horizontal groove, and think hard.

So, could it be a sequence? Han Nuowei suddenly thought of the Fibonacci sequence. He had an idea and did the math again: first calculate the middle, the 1 in the middle of the first gold medal and the 1 in the middle of the second gold medal, add 1 to get the 3 in the middle of the third gold medal, add 1 in the middle of the second gold medal and add 1 to get 5, assuming this is the missing number in the fourth gold medal, then the 3 in the third gold medal, add the 5 in the middle of the fourth gold medal, and add 1 to get exactly the 9 in the middle of the fifth gold medal!

Han Nuowei was so excited that he immediately calculated the number in the upper right corner, hoping to solve the answer to the fifth gold medal. In a similar way, the 3 in the upper right corner of the first block plus the 7 in the upper right corner of the second block needs to subtract 8 to get the 2 in the upper right corner of the third block, and the 7 in the second block plus the 2 in the third block needs to subtract 7 to get the 2 in the upper right corner of the fourth block. And so on, the 2 of the third block plus the 2 of the fourth block needs to be subtracted by 6......

Han Nuowei was stunned, and the result was negative.

He scratched at his hair, a little desperate.

Han Nuowei stared at the gold medal directly, wondering if it would be too complicated for him to think again.

At this time, a column of gold medals on the right came into his eyes, and he had not carefully observed the right side when he had just counted the numbers on the left. These five gold medals are the same size as the one on the left, except that they are all carved with the pattern of a cross.

Cotton was probably Catholic, but along the way, Han saw no other obvious religious signs.

What if it doesn't represent religion? Han Nuowei stared at the cross for a few seconds, and suddenly realized that this was a plus sign!

It turned out that Cotton had already made such an obvious hint that he had once again complicated the matter.

Being "deceived" by Cotton again and again, he suddenly thought that Cotton really looked like a psychologist. Han Nuowei smiled and made a list of equations in his mind: add all the numbers in the upper left corner, (4+1+1+4+3), and the result is 13, and then add the lower row of numbers, (6+4+3+3+1), the result is 17.

Suppose the result of the equation between 13 and 17 is 15, then, subtracting (3+7+2+2) from 15, the result is 1, so that the top right corner of the fifth gold medal is 1.

13, 15, 17, assuming that the numbers in the middle are added to result in 19. Then, 19 minus (1+1+3+9) equals 5, and the number in the middle of the fourth gold medal is 5.

Han Nuowei picked up the two gems of 5 and 1 and carefully placed them in the gap in the gold medal.

The round gold squeaked and spun, and then the metal beams all moved to the side, and the metal fence at the edge of the steps disappeared and the steps fell back to the ground. Han Nuowei took a deep breath and gently pushed the door open.

The light inside the room was not bright, even a little dark, and he turned on his flashlight and began to observe the cabin. The interior of the hut is very quaintly decorated: on the wall facing the gate is a patchwork of flowers and vines. Bookcases are symmetrically placed on either side of the wall, on which many books are arranged. Next to the bookcase on the left, there is a small round table with a red velvet tablecloth on it.

Han Nuowei had just taken two steps into the house when he suddenly stopped.

A sense of incongruity filled his mind. He took two steps back, looking at the two statues of cherubs that were almost as tall as a human in the room, near the door. The two statues face each other, both have pedestals, and both have classic shapes ready to fly, the difference is that the one on the left holds a trumpet in his hand, and the one on the right holds a gong in his left hand and a gong mallet in his right hand.

Needless to say, the trumpets and gongs, as well as the gong mallets, are pure gold.

Han Nuowei stared at the little angel on his right, a little puzzled: Why did it play a traditional Chinese instrument? He recalled that Mo Aogu had taught him that gongs had been introduced to Europe in ancient China. In 1791, the French composer Gossec used gongs in his orchestral works.

Cotton lived in the mid-to-late nineteenth century, and he knew the gong as an instrument. However, it was not popular to play gongs in Europe at the time, and the little angel always looked a little out of place with the gong.

Han Nuowei looked at the gong in the little angel's hand for a while, smooth as a mirror, without any patterns. He tentatively stroked it, but the gong didn't respond. He was a little bolder, pushed the gong, and watched it sway trembling in the little angel's hand for more than ten seconds.

Nothing has changed around them.

What if you struck this gong with a mallet?

Thinking of this, Han Nuowei looked back vigilantly, the blue gate was still standing there, and the statues on the chessboard square were also standing silently. He looked down at his feet again, and there was no change, no gaps appeared.

Don't fall into any more holes!, he prayed secretly, and then took the mallet from the little angel's right hand and struck it against the center of the gong.

With a "bang", Han Nuowei subconsciously clenched the gong mallet in his hand. In this almost maddeningly quiet seabed, the sound of striking a gong is really frightening.

Suddenly, the statue of the cherub on the left slowly turned, and after a few seconds of spinning, it stopped again, from the cherub facing to the right, to facing the gate.

Han Nuowei cheered in his heart, there is indeed a mechanism here!

After the little angel statue rotated, a dark grid was revealed on the base, Han Nuowei took a flashlight and saw that there seemed to be something inside, so he cautiously reached in and touched it, fortunately, that thing could be taken out.

This is a ceramic model of a ship, extremely exquisitely made, oddly only halfway. It is the size of half a ping-pong ball, and the mast and spinnaker are quite detailed and realistic, but there is no cabin. The hull is almost solid, with a small groove in the middle, as if used to hold the other half.

Where is the other half? Han Nuowei pondered for a while.

Since the statue of the cherub on the right can open a "voice-controlled" mechanism, what about the one on the left? Han Nuowei looked around the "trumpet" curiously for a while, but found nothing. The trumpet is fixed in the hands of the cherub, and if you want to take it off, you will have to destroy the cherub.

He sighed, the trumpet is not like a gong, as long as there is a gong mallet can be struck. If you want to blow the trumpet, you have to aim at the mouthpiece. But the trumpet was fixed to the left hand of the little angel, and the little angel was now facing the door, and it was so close to the door that he couldn't reach the mouthpiece.

Han Nuowei looked at the trumpet for a while.

Suddenly, he laughed, and it was he who thought about it again. Each trumpet has three pistons on it, and by pressing the pistons, you can change the sound of the trumpet. If you want to activate the mechanism, you don't have to let the trumpet make a sound, in theory, as long as you simulate the necessary actions to make a sound, you can do it.

As soon as he said it, he immediately approached the little angel on the left and pressed the piston in the middle. Han Nuowei didn't know which piston was the right one, he just thought of the one in the stone ball passage before, and the final correct answer was the one in the middle of the three doors. Based on that experience, he guessed that Cotton would habitually put the correct answer in the middle.

Sure enough, as Han Nuowei pressed the piston, the little angel on the right also moved, and its rotation direction was just the opposite of the little angel on the left, which was counterclockwise. After a few seconds, the little angel stopped, and a dark grid was also revealed on its base.

Han Nuowei couldn't wait to take out the things in the dark grid, and as expected, it was the other half of the ship model. He fitted the silhouettes of the two parts of the model together, and only a slight "click" was heard, and the two halves of the model were tightly clasped together, turning into a complete boat.

He turned the hull upside down and saw a round metal button embedded in its bottom, and the pattern on the button was extremely intricate. He tried to press it, and found that the metal button was fixed to it and could not move. He lifted the boat up again and shone it with a flashlight, trying to illuminate it for a closer look.

However, no matter how much the flashlight was pressed, there was no response. Han Nuowei was a little panicked, and tossed and turned for a while, but the flashlight still couldn't be lit.

Han Nuowei felt a burst of chagrin in his heart: I don't know if the flashlight is broken or there is no electricity. He didn't know when he would be able to return to the ground, and all that was left was the faint light source above his head. To conserve electricity, he turned off the overhead light, and then he looked at his diver's watch. At this moment, a full six hours have passed since he entered the water.

Ma Dui, a liar, also said that everything on his ship was American, but it didn't light up so quickly. Han Nuowei was speechless for a while, but still received the flashlight into his waist bag.

Han Nuowei slowly walked into the hut.

He walked to the bookcase on the right, curiously pulled out a book, opened it, and found that there was only the cover, and the inside was empty. Of course, he thought to himself, there would be no people living here, so books were just decorations. Han Nuowei checked all the books and found no clues.

He walked over to the small round table again and lifted the tablecloth. To his astonishment, there were many strange curvilinear patterns carved on the tabletop, which were intertwined and intricate, and there were many small circular holes scattered on the top of the patterns.

With such a table, it's no wonder that you have to lay a tablecloth, otherwise you can't place things, and it's not even at all. Han Nuowei thought mockingly.

Suddenly, there was a wave in his heart.

He took out the ceramic boat from his fanny pack and looked at the metal buttons on the bottom of the boat. The metal buttons seemed to be the size of the small holes on the table, and he immediately aimed at one of the small holes and pressed the ceramic boat on. When the boat came into contact with the hole, it seemed to be sucked through it, and it was embedded in the hole. Then, he heard a "click", and the boat seemed to bounce up a little. He crouched down and glanced along the edge of the tabletop, and sure enough, there was a piece of metal attached to the boat's metal button.

Han Nuowei got up and looked at the boat, and then looked at the patterns on the table, the more he looked at them, the more he felt that these patterns looked like a waterway! Could this be that he wanted to use this boat to "sail" on the table?

In the upper right corner of the table, three small letters are engraved, "END", which should be the end. But where is the starting point? Han Nuowei looked around, but found no other letters on the table. So with the mentality of giving it a try, he casually slid the ceramic boat forward from its current position. The curve of the ceramic boat gradually lit up, as if to imply that he was doing the right thing. Han Nuowei happily slid the ceramic boat one step further, but the curve that had been brightened slowly darkened again.

After tossing and turning for a while, he began to react: this is the traditional one-stroke painting. The ship had to go through all the curved "fairways" on the table without going through the same path until it finally reached the "END".

Compared with the previous problems, this is simply a "welfare", he secretly laughed in his heart: Cotton must not have imagined that in a hundred years from now, in China, there will be many children who will play the game of drawing at a very young age.

It didn't take much time for Han Nowei to finish painting the "channel" of the ceramic ship, and when the boat reached the small circular hole of "END" in the upper right corner, all the channels were lit up. Then, a thin drawer popped out from the side of the round table, and in the drawer lay something wrapped in satin.

Han Nuowei took out this thing and opened the silk, but inside was a thin board. He couldn't tell what the sheet was made of, but felt that it was softer than glass to the touch, more elastic than plastic, and it looked a little like it was made of the skin tissue of some animal.

Han Nuowei put the thin plate close to his nose and sniffed it, there was a soft aroma that smelled good. He looked at it several times and found that the sheet was not uniform, transparent in some places and completely opaque in other places.

Han Nuo pondered for the only time he couldn't understand, so he wrapped the thin sheet again in silk and put it in his waist bag.

He left the round table and continued to look around the room. After the "fairway" was all lit up, the room was much brighter. The interior of the house is not gorgeous, but it is not shabby, there is a fireplace, a sofa, a coffee table, and even a row of bells calling the maids.

Bell?
