Han Nuowei rushed to the door and thrashed wildly, but the stone door did not move. www.biquge.info The original design of this stone door was to be opened and closed by the gemstone badge on the outside, but now he is inside the door, and what he does is in vain.

Although he was not without caution along the way, he underestimated the lure of gold to a poor fisherman. What's more, taking away his gas cylinder at the bottom of the sea in this world means that Rawudu can have more chances to escape.

Although Han Nuowei was angry, he didn't hate Rawudu, but felt a little guilty, because he didn't have time to tell Rawudu, and there was likely to be a deadly mechanism on the other road.

"Humans are the only animals that blush, and perhaps the only ones who should blush. Han Nuowei leaned his back against the stone gate and muttered to himself. He sighed, wiped his sweat, and picked up the flashlight that had fallen on the ground.

It was an empty room, about the same size as the gray prison he had been locked up in Yin and Yang. He looked at every corner, there were no furnishings or strange looking places, like an empty gray prison, but the gray prison still had a window, he couldn't help but laugh at himself.

However, a new question arose in his mind: why did Cotton build an empty chamber on the side of a fork in the secret passage, just to trap the treasure hunters of the Unkind Society, so why not just kill him with a trap?

Han Nuowei thought to himself that since he was launched, so many problems have been solved, and he will never be trapped in this "submarine gray prison" so helplessly. Many of the traps in front are hidden in inconspicuous places, and it is likely that this "gray prison" has a similar design. So he walked slowly along the wall of the house, knocking on the wall with the back of his tool knife as he went. Suddenly, he stumbled and almost tripped over something. Han Nuowei's spirit was lifted. He turned to shine his flashlight on the ground and saw a pile of round stone balls, of various sizes and scattered irregularly everywhere.

Han Nuowei picked up the smallest stone ball and weighed it, it weighed about two or three catties. He counted nine stone balls, each with a pattern on it, and the pattern varied. He looked at it for a moment and realized that the patterns were astronomical symbols of the eight planets, and that the one that was particularly large, with a circle and a spot in the middle, was the sun.

Behind the stone balls, there is a long stone channel, which seems to be used to place the stone balls. Han Nuowei tried to put the outermost Saturn, which was painted like an H symbol, but there was no response. He put the stone balls representing the sun in again, and when the sun touched Saturn, the two stone balls actually lit up. Han Nuowei was amazed, and put the stone ball representing the earth into it, and the moment the earth touched the sun, Saturn and the sun both dimmed.

It seems that as long as you place them in the right order, you can make all the stone balls light up. Thinking of this, Han Nuowei began to painstakingly recall the positions of the major planets in the solar system. From the time he entered the water to now, he has consumed a lot of physical strength, and at the moment he is hungry, and his brain is starting to become difficult. After thinking about it for a long time, he finally remembered that in order of distance from the sun, it should be Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Han Nuowei immediately lined them up in this order, however, to his dismay, not only did he not touch any mechanism, but also the stone balls lit up for a while, didn't light up for a while, and finally didn't light up at all.

Is it to be arranged in order from far to near? Thinking about it this way, Han Nuowei reversed the operation again, but it was still useless.

"If it has nothing to do with the concept of distance in astronomy, then how should it be arranged?" Han Nuowei muttered to himself.

He was puzzled and irritable, so he had to casually arrange the stone balls randomly, trying to find the pattern of their arrangement.

When Venus slipped behind Uranus, the two stone balls lit up.

Han Nuo was stunned, how could Venus be behind Uranus? He thought about it carefully, Venus is Venus in English, and Uranus is Uranus. In alphabetical order, the V comes after the U.

Han Nuowei suddenly patted his head, how could he forget this? He tried to silently recite the English names of the eight planets, plus the sun, which were: Earth, Jupiter, Mars, Mercury, Neptune, Saturn, Sun, Uranus, and Venus.

He carefully arranged the stone balls in the order of Earth, Jupiter, Mars, Mercury, Neptune, Saturn, Sun, Uranus, and Venus.

From the moment he placed the second Jupiter, the stone balls lit up one by one, and finally, all nine stone balls lit up. In an instant, the "gray prison" was as bright as day, and Han Nuowei looked at this scene in surprise, as if he felt the power from the light. He couldn't help laughing: it was really arranged in alphabetical order of the English names of the planets, and Cotton was so clever that he almost stumped him by arranging such a "clever" game.

Slowly, the fluorescence dimmed, and then in the gradually dimming secret room, there seemed to be nine small candles jumping, and then, another rumbling sound sounded, and on the wall opposite the stone door, a stone slab slid up, and then, a stone window more than half a person high appeared.

Han Nuowei curiously raised his flashlight and shone it behind the stone window, which was facing a dark corridor, about one and a half meters wide, which looked very narrow.

The sudden "click" startled Han Nuo, and he looked down to see that the stone ball representing the sun had cracked for some reason, and something had fallen out of it. When he picked it up, it was a white shard.

Han Nuowei hurriedly took out the other three pieces in his waist bag, and compared them, it was indeed the fourth piece that was missing. After the four white pieces were put together, a face appeared, but Han Nuowei couldn't tell what kind of face it was—there were peculiar patterns on the forehead, the nose was particularly fat, the eyes were far apart, and the mouth seemed to be cracked—it was a strange face that was intimidating.

Han Nuowei was bittersweet, happy that he had finally collected all the fragments and didn't have to worry about it anymore, and worried that he didn't know where to use this terrifying face. He plunged from a shipwreck into a secret passage to the bottom of the sea, but the people outside knew nothing about it. Even if Madui sent someone down to look for him, I am afraid he would not be able to get in. Whether you want to find a treasure or find a way out, you can only rely on yourself in the end.

Han Nuowei put away the fragments and cheered up. He picked up a piece of the "wreckage" of the "sun" and threw it into the corridor behind the stone window.

After the stone hit the ground, it just rolled to the side, and there was no movement.

Han Nuowei waited a little longer to make sure that there was no mechanism, so he gently supported his hands and jumped in from the stone window.

However, he had barely walked a few steps when he heard the sound of a mechanism running under his feet. He subconsciously wanted to jump back, but then there was a deafening roar, like the movement of a landslide, which shook him off balance and fell to his knees. Han Nuowei was shocked, raised the flashlight, and shone towards the roar.

A large stone ball more than half a person tall rushed over, feeling that it was about to come to him in the blink of an eye, Han Nuowei didn't have time to react otherwise, so he had to quickly bite the flashlight in his mouth, and then jumped up and kicked the wall against the wall, while supporting both sides with his hands and legs, hanging in the air.

The stone ball hit the stone window with a "bang", and Han Nuowei breathed a sigh of relief and jumped down.

Unexpectedly, the stone ball stopped for less than two seconds before it began to roll back again. In an instant, Han Nuowei was about to go crazy, and before he could catch his breath, he was forced to jump on the wall again.

Han Nuowei looked at the stone ball rolling back, feeling very passive, thinking to himself if this thing should wait and come back, right? He waited patiently for more than ten seconds, and after a dull "dong", he prayed in his heart, must stop, must stop. But it backfired, and about two seconds later, the stone ball rumbled back again.

Han Nuowei smiled bitterly, this thing is really evil. He took a deep breath and began to analyze the current situation. Looking at the movement of this stone ball, it is very likely that it will keep rolling back and forth like this, he can't go down, and hanging on the wall all the time is not a solution, after all, it is very physically exhausting. He turned his head and saw that he was relatively close to the stone window, so why don't he go back first? But turning back is a dead end, and if he wants to live, he must go forward. As soon as he thought of this, the stone ball hit the stone window with a "bang".

Han Nuowei decided to move on.

As soon as the stone ball rolled under his feet, he immediately jumped off.

As soon as he landed, Han Nuowei held a flashlight and shone on the walls on both sides and began to observe carefully. Unsurprisingly, to his left, there are three stone doors. Each stone door is carved with a different pattern. The first door has two small flowers carved on it, the second door has a few more tiny leaves and stems than the first, and the third door has only leaves, no stems and no flowers.

With a "bang", Han Nuowei's heart tightened. "Boom", the stone ball rolled back again, and he sighed helplessly.

What is now certain is that it takes about fifteen seconds for the stone ball to roll from one end to the other, and if it takes fifteen seconds each way, it will take thirty seconds to go back and forth. Then, with the position he was in now, he could stay for about twenty seconds after the first landing. Combined with the physical exertion, it will become more and more difficult to climb the wall, so the time he spends on the ground will gradually decrease. He hoped that he could figure out the information on the three stone doors as soon as possible, so as to unlock the mystery of the passage. Because the further he goes in, the more passive he becomes.

Seeing that the stone ball was about to arrive in front of him again, Han Nuowei stepped on the wall with a "pout" and thought about it: behind the three stone doors, there are theoretically stone rooms, and there must be only one stone room that he is looking for, and the other two are probably organs.

When he was looking at the door just now, he noticed that the flowers of the first two doors were the same, and the leaves of the last two doors were the same. There are flowers without leaves, flowers with leaves, and leaves without flowers, and it seems that only the second type is more common. But if that's the case, it's too simple. Han Nuowei did not dare to take it lightly, he knew that Cotton was an expert in botany, well-informed, and it was not impossible to use some rare plant as a riddle.

Han Nuowei had a headache when he thought about it, he looked down and saw that the stone ball was rolling under his crotch, and when he was about to jump down, his eyes suddenly lit up. On the surface of the stone ball, there seems to be something.

Han Nuowei jumped down and chased the stone ball. He tried to get as close as he could to the stone ball so that he could take a closer look. But after a few seconds, he realized that what he had just seen seemed to be just a small piece of the pattern. As the ball rolled rapidly, it was impossible for him to see what it was or determine its location. After the stone ball "bang", he was startled, and instinctively kicked on the wall, this time, he was scared out of cold sweat, the stone ball would only stay for two seconds, he patronized and thought, and almost died.

After stepping on the wall, he quickly adjusted the flashlight in his mouth to let the light shine on the stone ball. Although he only looked at it for a moment, he could be sure that there was nothing on the surface of the stone ball. After the stone ball rolled under the crotch, Han Nuowei jumped down to rest, his brain thought quickly: after the stone ball began to roll, it rubbed against the wall, and the ball would keep spinning, so when the stone ball rolled to both ends of the passage, the contact point between the stone ball and the wall was random. Therefore, if he wanted to understand what the surface of the stone ball was, he could only stay by the stone window, or stay where he was now. He could only see clearly when the orb had stopped, and it happened to be the object's position facing up.

The stone ball rolled back again, and Han Nuowei hurriedly went up to the wall.

After tossing about seven or eight times, Han Nuowei finally saw the secret of the stone ball.

On the surface of the stone ball there is a square opening half the size of a palm, and inside it is embedded a golden square object. The square inlay is about a finger long in depth, and the four corners are just in the middle of the four sides of the opening, like an ancient diamond-shaped window. In addition, the four corners have straight grooves, like tracks.

Seeing those four tracks, Han Nuowei could almost conclude that the contents could be taken out. He waited a few more times, and when he finally saw the square facing upwards again, he quickly reached for it. But he exerted a great effort, and the square was unmoved. The stone ball paused for less than two seconds, and he quickly retracted his hand.

Han Nuowei jumped to the ground, he was already going crazy, jumping up and down over and over again, he was exhausted, and he finally touched the square, but he couldn't take it out. Cotton is really torturous enough to design such a mechanism.

Han Nuowei thought about it, but still felt that the key points were on those four tracks. Isn't there a track to guide the direction of movement of the objects embedded inside? If you can't catch it, do you need to push it?

Han Nuowei suddenly realized and stepped on the wall again.

After the stone ball rolled back and forth a few more times, he finally waited for his chance.

When the stone ball stopped, Han Nuowei grabbed the square object and pushed it hard. A strong rebound force reached him, and he pulled it out.
