It's a bizarre world, a bizarre world of ice and snow.

This is a cave with only a hundred thousand square meters, the wind blowing from the entrance of the cave hovers in the cave with warm and humid air, the humidity in the air turns into flying snowflakes under the action of low temperature in the cave, and the wind that loses temperature and humidity blows out from the exit of the cave with the cold and snow on the ground.

"It's cold. The thin Vivien rubbed her face red from the cold, and complained in a low voice: "I knew I had brought a tent with me, and a tent could still block the wind." ”

"You can't use a tent here. Lina sat cross-legged on her backpack with a big grin, and at this time her eyes lifted from the book: "The ice is too hard, it is difficult to set up the tent." Speaking of which, you are the only one of the four of us who should not be afraid of the cold, your cold place is only your face, but my whole body will be cold, and I should complain if you want to complain. ”

"You're wrapped in such thick clothes so you won't get cold. Vivien waved her little hand and accentuated her tone: "As for the face, you have such a thick skin, of course you won't feel cold." ”

"Vivien. Catherine glared at Vivien and said with a slight rebuke: "I said it, but you are the only one, you are not allowed to leave the scope of the hedron unless necessary, and quickly withdraw your hand." ”

"Why is it just me? Vivien protested dissatisfied, but seeing Catherine's stern eyes, she withdrew her hand back to the side of her body: "Okay, okay, I see." ”

Rachel watched the interaction of the three girls with some curiosity, and some curious about the ban Catherine gave Vivian alone, and wanted to ask the reason, but she couldn't say anything.

"It's nothing. Although Vivien didn't look at Rachel, she seemed to know the doubts in her heart: "My hands don't feel cold, and the eldest sister is afraid that I will feel frostbite on my hands, so she set this rule for me." In fact, how can it be so exaggerated, the eldest sister is just blindly worried. Well, I won't say anything, don't stare at me. ”

Catherine shook her head and smiled bitterly, lowered her head and used the metal rod that was originally used as a crystal lamp holder to reach into the ice cave several meters deep, stirring the water at the entrance of the cave to prevent the water from freezing again: "Pennis has been going down for more than two hours, he should be coming up, right? After all, the time limit for underwater breathing drugs is only two hours." ”

"Eldest sister, don't worry. Lina waved her hand nonchalantly: "According to him, there are no monsters under the water, so he will not be in danger." ”

"Forget it, I'm not waiting here. Vivien said and stood up: "I'll go and lie in the sleeping bag for a while, even if I can't rest at night for seven or eight days, my head will hurt to death." It's rare that it's safe here, so I'll go and rest for a while. ”

Catherine waved her hand: "You and we can rest in between, and we can take care of it." By the way, cover your face with something to keep out the wind. ”

"Know~Dao~la~" Vivian stretched her voice and said, "Long-winded eldest sister." ”

Catherine snorted angrily, but her eyes were full of pity as she looked at Vivien's back. Although Vivian had her back to Catherine, she knew exactly what Catherine was thinking, and said leisurely: "Sister, don't be like this, I'm fine, it's too good, not reluctant at all, don't feel sorry for me." ”

"You're smart. Catherine complained in a low voice, and suddenly felt the resonance crystal in her pocket vibrate, and quickly put away the metal rod: "Pennis is coming up." ”

Before the words fell, there was a sound of water, and the pannius fish generally jumped three or four meters high from the water, and landed lightly beside the crystal energy stove lit in the center of the girls. He wiped a handful of water from his face, and while reaching out to take the activated fire attribute spar handed by Lina and putting it in front of his face, slowly relieving the numbness on his face, he said, "Everyone is okay, what about Vivien?"

Vivien wanted to rest for a while, she could hear her, but she didn't bother to speak while she was resting, so she didn't bother to speak. Catherine said, "You didn't freeze down there, did you?"

Pannis felt that his face had warmed up, so he picked up the boiling water that had been heating on the stove and enjoyed the warmth of the water vapor: "Actually, it's okay, the water is warmer than this." ”

"Did you find the entrance?" Catherine relieved herself when she heard Pannis say that it was okay.

"No, I was fooled. Pannis's face was disgruntled.

"What's wrong?" said Catherine, frowning, a little worried.

"It's not a matter of intelligence. Pannis shook his head and explained, "Legend has it that there is a small lake in the center of this cave, and it turns out that it is. But who knew that this whole cave is actually a lake, and the scope of the lake includes the entire cave, and it is at least more than 30 meters deep, so the scope that needs to be explored is too large, even if you simply look at everything, it will take a long time. ”

"That's why I said I'd go down and help you explore together. Catherine was unhappy that she couldn't do anything.

Pannis picked up another bottle of underwater breathing potion and put it in the pocket inside the waterproof leather suit, and once again refused: "Forget it, you are not an explorer, and it is useless to go down." And there are not many underwater breathing agents, so let's save some use. ”

"You're going down again?" Catherine was a little worried when she saw Pannis's actions, "Do you want to rest for a while?"

"No, I have some ideas, I need to go down to verify it, if I'm lucky, I should be able to find the entrance next time I come up. Pannis walked to the hole in the ice and smashed the surface of the water, which had frozen after a few minutes without stirring, with a metal rod: "Be careful on it, it's not completely safe here." ”

"We'll be careful, and you'll ...... Well, already down. Seeing the splash in the ice cave, Catherine pursed her lips helplessly, and glared at Lina who was snickering: "Don't laugh, you have a lot of ghost ideas, come over and let's discuss, you can help me find a way." ”

"What can you do?" Lina sat down close to Catherine, her demeanor was quite rough, her eyes glanced at the ice cave, and suddenly said, "What do you mean......"

"Yes, that's it. Catherine smiled apologetically at Rachel and whispered to Lina. Rachel consciously moved a few steps away, avoiding the two who were quietly communicating.

——————————————

"Temperature, temperature. As soon as Pannis got out of the water, he destroyed the four fire attribute crystals in various parts of his body through the waterproof leather suit, so that the whole body was soaked in the cold water without any temperature protection, until the body completely adapted to the temperature under the water, and then began to swim slowly, and the thoughts in his mind turned quickly: "The research institute is built near here, and it must be provided with energy by absorbing the energy of the ice element here." It is inevitable that the temperature on the side of the institute will be very slightly higher than that on the other side. Then, as long as you feel the small changes in temperature with your heart and follow the changes, you can always find it. ”

Having made up his mind, Pannis focused most of his attention on his skin, carefully sensing the change in the temperature around him as he tentatively moved around.

"Sure enough, there is a difference. Pannis said secretly in his heart: "The more you go this way, the more obvious it becomes, it is estimated that to the very edge, the temperature can be raised to the point that anyone can see the difference, it seems that this is the side." ”

Thoughts swirled in his head, and Pannis swam faster and faster, and soon he reached the edge of the lake, slowly searching along the rock face.

"Sure enough. As he approached the bottom of the lake, Pannis clapped his hands, looked with some joy at the entrance of a dark hole in the rock wall, and thought to himself, "If nothing else, this is it." But just to be on the safe side, I'd better go check it out first. ”

Tentatively swimming into the cave, Pannis found that it was a passage with a slope of gentle slope, and the end of the passage should be several thousand meters away. After swimming a few hundred meters along the ramp, traces of artificiality can already be seen around the ramp, and a few hundred meters further, the surrounding rock walls have been replaced by artificially created stones.

Swimming to the end of the ramp, Pannis found that it was a shaft more than ten meters deep, and there was a metal ladder on one side of the shaft for people to climb, but the metal ladder that had not been maintained for hundreds of years had long since been rusted and unusable.

Above the shaft, you can see the soft light. Already sure that he had found his target, Penis reflexively re-entered the water and quickly returned. After swimming for a short time, Pannis suddenly felt a vibration of the resonance crystal under the waterproof leather suit.

"It's a sign of condition on it. Pannis's heart sank, but he slowed down his swimming, getting closer to the hole he came from, and kept his swim as silent as possible. When I arrived at the entrance of the cave, I found that the hanging metal rod was still stirring the water very slowly to prevent the ice from condensing again.

Seeing this scene, Pannis understood that Catherine still had room to spare, indicating that the situation had not yet reached a very urgent level, so he reached out and tapped the resonance crystal to send a signal to it. It wasn't until he saw the metal rod retracted that Pannis quietly surfaced, and as soon as he came out of the water, Pannis found an anomaly, the crystal lamp on it had been extinguished, and the ice was plunged into darkness.

Confused, Pannis tapped the Resonance Crystal again, only to find that the crystal quickly responded with vibrations, and at the same time heard Catherine's low voice sound from above: "Come up." ”

It wasn't until he heard Catherine's voice that Pannis was completely relieved, reaching out to destroy the two light sources on his helmet, plunging himself into darkness, while supporting the sides of the ice cave with both hands, trying to crawl out of the cave without making a sound. As soon as he came out of the cave, he touched Catherine's outstretched hand, and after he held it with a little hesitation, he was pulled down by Catherine, and whispered in his ear: "Just now I vaguely saw a figure shaking at the entrance of the frozen hell. I'm pretty sure it's a person, but when the Crystal Lamp is extinguished, there's no halo from the Light Crystal, which is weird, except for the Shadow Hand guys, I've never seen anyone move around in such an environment without illumination. ”
