The heat and humidity made the air a little less oxygen, so that no matter how much the three of them adjusted their breathing, there was no way to calm down their heart rate.

Urging the formation with all their might, the three of them still took off all the coats on their bodies, leaving only their close-fitting underwear.

Ji Xiaoran felt the benefits of his state at this time. She grouped herself as hard as she could, her two little eyes looking at the cave in the light.

The disgusting-looking, dark red stones gradually turned gray as they went deeper into the darkness, until a cauliflower-like gray matter began to appear on them. The surface was covered with filaments that seemed to be woven of light, and it looked crystal clear in the white light of light and dark. However, in some places, the filaments are piled up and twisted into clusters, making it look more like a cocoon woven by an insect in the ground.

"What is this?" Ji Cheng stretched out his hand with some curiosity, but he was worried that it was something poisonous, so he didn't dare to touch it.

"Lime?" Ji Xiaoran had a little impression of the stone that looked like a pile of snowflakes in this white flower, but it didn't look like the limestone in the cave.

I probably saw it in a documentary.

"What is lime?"

"It's a hot stone in the water, and it's so humid here, so I think it's probably lime." Ji Xiaoran pointed to the rocks that were not covered by "snow", which had already condensed and were full of water droplets.

But Ji Xiaoran was even more worried that they would be dehydrated. The human body is more likely to sweat in hot and humid environments than in hot and dry environments, which can lead to dehydration.

"It's too hot in here." Ah Rishan was glad that he had already taken Fuxi Dan, otherwise his original self would have died of heat here, "I'm afraid this temperature is already higher than on the sand dunes, right?" ”

This is not in line with their so-called common sense: the more you go underground, the cooler it should be?

"Medicine!" Ji Ying suddenly remembered the medicine bottle Tengger gave them, and immediately took out a blue pill from it, "I remember that this is for the heat?" ”

The other two also reacted randomly. The entrance of the pill turned into a coolness and directly integrated into their spiritual power, and as the spiritual power circulated in the veins, the excessively high body temperature began to drop, and even the heart rate slowed down a little.

Qi Pi exhaled, and a mist of water condensed directly in the air.

"Wow, I feel like I'm next to a mobile air conditioner right now." Ji Xiaoran moved to the top of the snake's head, "This temperature is a little cool for snakes." ”

"Your teacher is amazing." Qi Qi and Ji Cheng didn't know how to refine medicine, so they had to be amazed, "I just don't know how long a pill can last." ”

Three of these pills were eaten, and there were three left.

"It's the first time I've eaten something like this, too." Ah Rishan spread his hands, "I can only rush forward as much as possible." ”

The confrontation with temperature turned into a race against time. The uncertainty of the drug's effect forced them to speed up their pace, which also caused their clothes to gradually get wet, and they didn't know if it was the dampness or sweat in the cave.

"You'd better slow down." Ji Xiaoran relied entirely on his body to surround the Qi Qi so that he would not be left behind by their running and jumping movements, "The high temperature is already physically exhausting, and you are sweating so much, and the ground is uneven." ”

"Anyway, with so much physical strength, try to have a chance to move forward." Qi Qi chuckled, "Look at Ah Rishan, although he has begun to breathe, he is so excited." ”

Of course he was excited. Ji Xiaoran rolled her eyes in the bumps: it was like a captive puppy could finally run freely.

"What are you afraid of, I haven't disappeared." She muttered quietly.

"If you do disappear, does that mean we should all be here?"

Ji Cheng turned around suddenly, "Ah Qi, you move faster, and you have been thinking about it in the back." ”

Following the footsteps of the light, the cave in front of it was no longer as white and monotonous as a snow cave, and sawtooth and edges gradually appeared on the rock wall, and the transparent crystals reflected the light.

It looks like snow has turned to ice, but the temperature is a lot hotter.

The trio were already feeling the effects of the medicine wearing.

"Doesn't that look like a hedroon?" Ji Cheng finally didn't suppress his curiosity, and touched it with his hand, the texture seemed to be very hard, but it was definitely not as good as the spare, and there was no spiritual power in it.

"It's crystal, isn't it?" Ji Xiaoran's little head leaned over directly, and then his body almost bounced back directly on the head of the monkey, "I remembered!" It wasn't lime, it was plaster! Below this is the Crystal Cave! "TV updates the fastest//

"You know this? Are crystals dangerous? He felt the guy above his head shivering.

"Anhydrite slowly concentrates water and sulfate, calcium molecules, to form this clear gypsum crystal. It's not dangerous, it's the crystal cave that's dangerous. Ji Xiaoran's voice was trembling, "Now you are only feeling hot flashes, but in the crystal cave, its temperature will be higher, and the air humidity will be greater." At that time, if you are still in this state of cooling, when you breathe, the surface of your lungs is the coldest surface that comes into contact with the hot and humid air, and the water droplets will condense directly in your lungs, and you will die! ”

"And it is said that every drop of water in the crystal cave contains hundreds of millions of bacteria, which will also directly kill people."

"But there is no way back." Qi Pi's voice was solemn, "We may not be able to beat the spiders in the desert, and we can't go up without the power of space in the place where we come down." ”

Ji Xiaoran really felt like she was about to cry, "In the documentary, the best explorers only dare to stay in the crystal cave for three quarters of an hour without wearing a cooling suit. ”

"What does the cooling suit do?"

"It's like a garment with ice cubes and then a special mask that provides dry, cool air." Ji Xiaoran's tone was firm, "Anyway, you can't move forward anymore!" ”

"But is it possible that this place is different from what you think?" Seeing that the two people in front of him were waving to him, Qi Qi lowered his voice and followed, "After all, the interface we are on is not the same. ”

"How is the natural evolution of nature different?!" Ji Xiaoran's tail knocked on his head one after another, "The crystal cave is hot and humid!" ”

Crystals had begun to grow from the walls to the ground, turning the less than three-foot wide corridor into a dazzling walkway covered with sharp crystals.

The three of them began to walk carefully with each step, otherwise one of them could get the soles and skin cut if they were not careful.

The complete failure of the elixir forced them to stop and stand in the middle of the craggy spar. Their heart rate rises again, and it doesn't ease in the heat because their bodies need more oxygen, and the heat and moisture reduce the oxygen levels in the cave.

According to the message from the butterflies that were exploring the path, there were at least two miles left in the tunnel before entering a cavity that seemed to be covered with stones.

I think it's the so-called Crystal Cave.
