This is not the same time as it used to be, so be sure to complete your task before flooding the Crystal Cave. Guo Cheng is deeply aware of this. He was worried about the two of them in his heart, so don't be angry and quarrelsome.

How deep and long is the mysterious crystal cave?

The three of them did not reach the end at all. Before them, there was one person, and that was the old stationmaster, Deng Tian. With the help of a flashlight, he entered the crystal cave two or three kilometers by himself. Yesterday, a dozen of them only reached the depth of five hundred meters in the ice cave and discovered a huge miracle. Can you imagine what you will find if you go a few hundred meters further?

The three of them do not know that the iceberg here is one of the three largest and brightest locations on the Antarctic continent, covering an area of several tens of kilometers. The other is the Crystal Imperial City discovered by Wang Hu, and the other is the land of the once frozen spaceship, where there is a huge subglacial lake, the tip of the iceberg, and an alien research room, which is now garrisoned by the American stationmaster Rogge.

They didn't calculate the depth of 500 meters, and it took a few minutes. In my mind's memory, how is yesterday's picture very different from today's, and what is the reason? They all saw the suspicious caution in their hearts.

Guo Cheng has always been calm, generous, and decisive. Yesterday there were thousands of square meters of vast halls, and now a crystal pillar appears in the center, directly docking with the space above.

"Where did this come from? I didn't have it before. The pony asked, looking up.

"Yesterday, yesterday there was nothing here. Isn't it strange that it has suddenly appeared? It seems that someone is operating. Although Xiaohan was surprised, he thought calmly at the critical moment.

"Please be careful, let's go find the control room. Your crystal skulls are there. Guo Cheng was shocked in the face of the sudden change, but he didn't show it at all, and said to them calmly.

"There's no way to block the road, right?" Pony worried.

"Don't crow's mouth." Xiao Han immediately retorted.

"What kind of crow is I? Don't you have something to do? ”

"I'm not looking for trouble, am I? But your mouth has always been sharp. ”

"Hey, don't make any noise. What time is it? Race against time to know what? Guo Cheng said to them with a serious expression, what he was worried about had finally happened.

Pony and Han were angry when they saw the stationmaster on our board. However, the stationmaster doesn't seem to care about the strange appearance here.

They regained their tranquility, and followed the sudden appearance of not caring about the place, and followed the stationmaster to the certain place.

"Stationmaster, I have a question." The pony walked up to him and asked, "Now that the icebergs are melting, and the water is dripping outside, why is there no water dropping inside, not even a shadow of water, why do you say that?" ”

"You don't know yet, it's all made of crystal, how can the ice melt?" Xiao Han replied to him.

"No, that's not what I meant. I mean, why isn't there any water coming in? Could it be that this place is all sealed and not a drop of water can enter? The pony corrects his question.

Guo Cheng raised his head and looked up at the huge sky. Is it a huge sealed space? He was right.

Why is there no water coming in? There must be a secret reason. One of the biggest mysteries, how did they come to light? Where does the light source come from? I won't figure it out for a while, maybe only when I get to the real inside, maybe there will be an answer.

"That's how it should be." Guo Cheng replied to Pony's words.

"I'll say it. It's a huge complex, and it's completely sealed. Only when all the icebergs have melted, and in the summer of next year, when the Antarctic becomes the polar day, the true face of Lushan will appear. Pony added the point.

"You figured it out too. Yes, when the iceberg melts, the world can change beyond recognition. Xiao Han thought more far.

"Go! Who would have as much as you think? The pony replied dismissively.

"The country's leaders think more far-reaching, so they will send troops to garrison the scientific research station. It's definitely a top priority here. If nothing else, the advance force will be seen tomorrow and the next two days. "Han's thoughts are very different from his.

"It's no use when they come. When it's all water and ocean, who would risk their lives to burrow into a flooded crystal hole? Pony doesn't think so, and knows what the country is doing.

"You know what? What is the first opportunity, as expensive as a thousand gold? What would you think if you were occupied by the United States? Scolding my mother in my heart, it must be uncomfortable? What is a national strategy? Do you understand? The little man glanced at him, obviously a little angry, and he actually had a skeptical attitude towards the orders of the state.

The two of them began to talk to each other again, not paying any attention to the changes in the situation around them, and they had already arrived in the control room without noticing.

Guo Cheng paused and paid close attention to the slightest change in the control room. They almost hit my ass and alertly avoided it.

"We're here." Guo Cheng reminded them.

Walk in and put down the backpack, observe the tall chairs that are untouched, and go to the crystal chairs in front of you to see if the eight crystal skulls are there?

"Is our Crystal Skull here?" The pony said to take a look.

"Yes, they're still there." Guo Cheng replied to them.

"Wow!" Xiaohan put down the heavy backpack, stretched his arms and twisted his waist and said, "I'll take a look, I've been thinking about it all my dreams." ”

Pony and Han become affectionate brothers, observing and stroking the crystal skulls together, and they are delighted and loved.

Guo Cheng used a telescope hanging from his chest to look at the dense robots in front of him through the transparent crystal glass. They stood there majestically with a glittering crystal. This is definitely the control platform that operates the command robot. The eight crystal chairs will definitely sit with eight people directing the robot, and the tall crystal chair in the back, it is the commander-in-chief.

Putting down the binoculars, Guo Cheng returned to the tall crystal chair and took a closer look. There was a crystal platform in front of it, nothing left, but a small hole, the size of a female finger.

Why is there a small hole? Reminiscent of the eight crystal caves in front. They fit perfectly into matching crystal skulls. This small hole is also in the shape of a skull. There should be nine crystal skulls here, missing one of the smallest crystal skulls. Where is it?

"Hey, come and see." Guo Cheng called them.

They didn't respond.

Look back.

The two of them were struggling to move the crystal skull in their hands.

"Stationmaster, don't you think you can move out?" The pony barked bitterly.

"Me too." Xiao Han also said with a bitter face.

Guo Cheng tried it for himself.

It seemed to be locked inside and didn't move.

"No need to pull it out. They are locked. Guo Cheng told the two of them who didn't give up.

"Alas——! The greater the hope, the greater the disappointment. The pony sat down on the ground in discouragement.

Xiao Han sat with him, equally discouraged, "I wanted to hold it and sleep well." ”

"Come and have a look." Guo Cheng beckoned to the discouraged ones, "Look there's one less crystal skull here." ”

"Crystal skulls?" They heard in their ears that the crystal skull was about to come to their senses, and when they went to the place where the stationmaster pointed, it was indeed a small hole. The hole is shaped like a skull. There are only eight crystal skulls, so where did the smallest crystal skull go? The entrance of the cave is only the size of the female finger, so it is only the size of the female finger.

"You come here and wait. I'll look there. Guo Cheng suddenly knew.

"Oh, be careful." Pony and Han instruct the stationmaster.

"Hmm." Guo Cheng picked up his backpack and ran out.

"Hey, old friend. We've all been disappointed. It seems that we went for nothing. The pony gives up the idea of having it.

"Alas——, I'm not reconciled!" Xiaohan was still angry, "How is it possible?" Gently put it in, and now it takes a lot of effort to move it out. What do you think this is all about? ”

"Forget it. If it's not ours, it's not ours, and I can't help it. The pony laughed and patted his arm.

Xiao Han smiled relaxedly, "That's not bad." We entered the most amazing crystal cave in the world, and found one great miracle after another. Look at the countless robots in front of you. There is no greater mystery in the world than this. I think we're going to be big names in the world. ”

"Hehe, what you think is beautiful. Celebrities can't be eaten. Now the only thing is to help the stationmaster move a robot out. You said that we stood next to the robot and took a group photo, how majestic it was! It's better for the stationmaster to think. The pony couldn't help but smirk.

Guo Cheng ran to the room from yesterday.

It was filled with countless crystal chests. One by one, I rummaged through the cabinets, except for piles of dust, and I could no longer touch the crystal skull that I imagined in my mind.

Looking at this and that in disappointment, he looked like he had died of his son, and that look of eagerness was heart-wrenching.

Don't give up, never give up, it's the only possible hope.

Guo Cheng searched for them all again, and there was not even a ghost shadow.

Really deflated, Guo Cheng gave up walking out of that room, but he didn't give up looking back and fantasizing about whether there would be a miracle. In front of me is a huge crystal pillar, how can it be said that it has come here? Out of thin air?

Definitely not, there must be a reason. Who touched the switch system here? Was it because of our mistake yesterday? It seems to be, and it doesn't seem to be.

It stood tall and erected in front of him, which made Guo Cheng very interested.

It's full of magic.

Guo Cheng walked around it, estimated to have a circumference of forty or fifty meters, and a height of about ......? It seems that it can't look up at the top, and it extends all the way up to the top.

It couldn't find a trace, and it couldn't find a switch or anything, so it gave it up for now. What's the mystery about it? I will slowly find out later.
