I thought that the worst ending would be to starve to death in the secret room, leaving only a few corpses for future generations to admire. I never thought that if this place was squeezed down in all directions, it would not even be able to fall a whole corpse.

"Think of a way!"

"Think of a fart solution, if you can't find it, you can't find it?"

Just when they were arguing into a pot of porridge, Liu Shenghan suddenly spoke.

“…… Maybe it's not for us to find the lost one. ”

"What could that be?"

The three of them returned to Liu Shenghan's side and looked around the crystal flower at the tip of the cone. Indeed, the columnar space is much more cramped than before. The passage of time is also nerve-wracking.

"This petal is not lost."

Liu Shenghan said again. Immediately after, she reached out and pinched the mutilated place out of thin air.

"It's still there?"

"It's still there, but it can't be observed. It's crystal polished, like any other petal—a crystal that's clear. ”

Is that really the case?

Why can't I see it...... Is it because it is the same color as water? What color is water?

What color is water?

At this time, Bai Ya suddenly thought of something, and he pulled out a knife.

"Hey, what are you doing?" Qi Huan immediately became vigilant, "Don't cut down this flower, there is no way back." ”

"Shut up."

Bai Ya glared at him. I don't know if it's an illusion, he feels that Qi Huan's mind is even more noisy than when he speaks. Then, he turned the knife sideways and slowly touched the petals. He didn't exert any force, just made the knife surface come into contact with the petals.

Then, he removed the knife, and the crystal-carved Wa Sumire was missing another petal. Only three colors are presented to them.

Red, white, blue.

"What did you do?" Qi Huan asked, "How?" Is it ......?"

He didn't need Bai Ya to explain, he seemed to have figured it out. Legend has it that the molten stone of Nuwa to mend the sky fell with the fire of the sky, fell to the earth, and ignited the fire of the plain. The rain poured down, and the fire was about to be extinguished, and flowers bloomed, revealing the veins underground. It is a divine flower that gathers the power of the five elements, and each petal symbolizes a kind of power.

The sea is water, and Bai Ya's sword is gold. In this way, there is a way. Liu Shenghan immediately took out a pen...... No, it should be said that it is half a branch, a half branch that was cut off by the black. She used the pen made of bamboo to gently brush the other three petals, and the cyan petals lost their color.

Qi Huan carefully reached out his hand and touched the bare place, and indeed felt the invisible resistance—it was still there. So, he began to grope all over his body, and finally focused on his hands. Out of habit, he still had those white, now dirty strips of yarn wrapped around his arms. He put his finger into the crevice and scraped, feeling for a few very fine grains of sand. If it weren't for the situation, I'm afraid they would have been able to hide comfortably inside for a long time.

On the other two petals, he put two or three grains of sand on each. In front of everyone's eyes, the white crystal petals also faded their color. Now, all that remains of the originally beautiful fake flower is that dazzling red.

…… Where to make a fire?

A few people froze in place, you look at me, I look at you.

"Do mermaids need to face this kind of puzzle as well......?" Qi Huan was very curious about this.

"Stand back."

Frost Moon Jun suddenly raised his hand, and the others subconsciously stepped back when they heard his command. By this time, their backs had touched the cylindrical wall. They were all a little anxious about how quickly time had passed.

Before he had time to sigh more, his vision was suddenly wrapped in a miserable white, and all the scenes in front of him were shrouded in this white smoke. Is it white smoke? Or blisters, or something else? A strong cold current greeted them, and between the dense and frantic foam, several people vaguely saw the blue firelight. Does it burn under water, boiling the water? But what a few people could feel was not the warmth of the fire, but the biting coldness, and even the silk clothes could not stop this coldness.

Bai Ya raised his hand and found that the place covered with the thin cloth was covered with a thin layer of frost.

"What are you doing?!" Qi Huan exclaimed.

The gray color was distributed in all corners of the columnar chamber in an instant, and even the gas they inhaled in their lungs had a strange burnt smell. Several people narrowed their eyes and raised their arms to shield them, to reduce their uneasiness after being taken away from their sight. However, the anomaly disappeared sooner than they thought. When they felt that everything in front of them had calmed down again, they lowered their arms and found that their vision was much more empty than before. It's probably back to the way it was before.

The crystal cone and Wa Jinhua in front of them disappeared, and the front of the four of them was empty. If anything, it's the extra spiral staircase behind them. Admittedly, in their current situation, there is no need to "walk". But the staircase is a symbol, a guide, and perhaps it is also an architectural style that mimics the human style on land.

"What did you do?" Bai Ya asked Frost Moon Jun.

"A ...... Cold fire, fire of internal force, can burn under water...... You don't understand it after explaining it, so I'm too lazy to think about it. ”

This kind of arrogance has always been unpleasant, but arrogance matches ability. This kind of unreasonable style that is on the verge of a seizure is really annoying. Nuancai Literature Network

The spiral staircase that surrounds the wall makes it easy to entice one to go up the ladder. And they did.

The stairs were not long, and they soon came to the second floor. There is an extra light here compared to the first layer. Not the lights above, but the ground below. The ground is like a silver mirror, smooth and dazzling.

"Don't go yet." Liu Shenghan stopped Qi Huan, who was about to move forward, "It's not quite right. ”

"It smells of metal." Frost Moon said.

Sheng Han took out half a pen again and threw it towards the flat ground in front of him. It wasn't a cylinder, it certainly wouldn't roll, the half of the pen just fell to the ground, in front of them, motionless.

Then, the ground caved in.

It was engulfed - it's weird. Countless tiny, silver-white tentacles stretched out from the ground, and they picked up the half of the pen, pulled it hard, and dragged it hard under the floor. Under their astonished gaze, half of the pen completely disappeared from view, and the ground quickly became smooth as new.

Then, Liu Shenghan threw the other half of the pen out vigorously. You could see that she wanted to throw it far away as best she could. But soon there were silver-white tentacles again—thicker, more disordered, and they flew hungrily, grabbing the other half of the pen in a very strange way. The tentacles then pulled it into the floor again. After this more intense anomaly than the last, the ground returned to its original state, and there was no change in the slightest.

"Is the floor alive?"

"Mercury."

"How is that possible?!"

Qi Huan is not stupid, of course he knows what mercury is. But mercury should be very heavy, and everything should float on it. More importantly, how could mercury be alive? Like just now, like ...... Is there life like that? Of course, he had heard of the use of mercury as a trap or preservation in various tombs, but did it actively "hunt"? Like a living, unknown life?

It's so creepy.

"It's mercury." Frost Moon Jun was very sure, "It's just that some kind of spell has been cast." ”

"That's it?!"

It's useless to be surprised, you have to find a way to get over. But apart from the path in front of them, they certainly had no choice. Do you just swim there? They will be dragged into this crazy mercury and held to death until their lungs are filled with this liquid metal, and the slightest gas will be squeezed out, and the silk clothes will not save them.

"Why don't you try...... Conquering gold with fire? ”

Qi Huan tentatively made a suggestion, and Frost Moon Jun actually did so. His hand didn't touch the surface of the mercury, but hovered less than an inch away from it. Suddenly, a fierce fire ignited from under his palm, spreading to every corner of the mercury surface in an instant. At the same time, bluish-white frost marks slowly grow and spread on the mercury surface.

The translucent mercury completely reflects the eerie fire of the sea, doubling this confusional vision. The flames burned, distorted, and the blue and white smoke or bubbles struggled and writhed, causing the picture to be fragmented and turned upside down, and they felt varying degrees of discomfort.

As the pale frost spread, the fire faded and the whole field of vision darkened and became quiet. A thin layer of shell covers the surface of the mercury, like a snowfall.

"Now...... Can you go? ”

"You try?"

"No, why don't you explore the road first?"

"Why don't you go?"

Several people pushed and shoved, but no one dared to take a step. At that moment, there was a sudden sharp sound in front of me, as if something was drilling into wood or metal, very harsh. The ground in front of him suddenly cracked, and although there was no obvious tremor, the cracked marks were still unstoppable, as if the seeds buried deep in the ground had broken through the ground, ready to turn into a towering giant tree in an instant.

Again, they took a few steps back. Qi Huan turned around and found that the stairs that came up were gone, and there was no passage to the next floor. Behind it, only a round, flat ground that originally belonged to a spiral staircase remains. The floor here is also made of clear crystal, and is the only place where you can settle other than mercury. Through the transparent floor, they couldn't see downstairs either.

Several huge shadows fell on him. Qi Huan turned around and found that many rocks had risen from the ground. They were arranged in a very orderly manner, apparently on purpose. And the level of that layer of mercury has dropped. Bai Ya ventured out and found that the mercury had retreated to a barely visible position on the upper floor, and only a glimmer of reflection could be seen. The pillars of the reef resemble plum blossom piles. Do they grow directly from one layer, or do they come from deeper?

"The mercury reacts a lot to the barrel, perhaps because it's wooden. As for these reefs...... I think it's still about the Five Elements. Liu Shenghan continued to speculate.

"How?"

"Fire overcomes gold, and earth is born of fire."

"Ah, I see." Bai Ya reacted quickly, "The reef is soil, so you have to use wood." ”

And then ...... will lead to fire. Qi Huan deduced from this, "It seems that Wa Jinhua is just a hint. However, if fire is born with wood. That is, if we use wood against it, the Crystal Palace will burn again? ”

"Is there any other way?" Qi Huan said, "Aren't you going to jump the plum blossom pile now?" Will it collapse as soon as you step on it? I always felt that there were mechanisms everywhere, and there was no way to exploit them. ”

"Do you still have a talisman?" Bai Ya asked him.

"It's already broken." Qi Huan glanced at him, "You can't use it if you don't dry it." ”

You can't go down the crooked way, so you can only solve the problem honestly. The four of them looked at each other, and no one spoke for a while.

The atmosphere was eerily silent, more unsettling than any silence that had preceded it. Although there seems to be no time as a limit now, they also know very well that there is no way back for them. Even if the merman friends are still waiting above, they can't get out of the way. Seeing that the situation was not good, he couldn't run, so he could only move forward. This feeling is like an invisible knife on the neck, and if you are not careful, you will never see the light of day again.

What's going on......
