The weather was already very hot in early June, and Li Moyun, who was wearing a gray hoodie, came to the place where he had made an appointment with his father, (about the Yuzi branch of the Qinling Mountains.) He was already sweating, and if it weren't for the bad influence, he would have wanted to take off his shirt completely.

Passing by a small stream, the spring water slowly left from the mountain falls into a stone pool. It is said that the stream of the mountain stream is cool, no matter how hot the weather is, at least the spring water on the mountain is indeed cold and refreshing. Li Moyun saw this gurgling stream, like a traveler walking in the desert, frantically rushing to the edge of the stone pool, and 'whooshing' the water on himself.

Li Moyun, who was happy enough, finally set off to the mountainside again, and finally met Li Han and the two at the mouth of a strange cave.

"It's so hot, there's something wrong with June this year, it's too hot. The first thing Li Moyun said when he saw the two of them was to complain, of course, Li Yun looked at his appearance and knew that this thing was lazy again.

Li Hantou said casually without replying, "When you are cool for a while, we are walking in a karst cave this time, the temperature is very low, don't be too cold when the time comes." ”

Li Moyun's expression is very exciting, and the black question mark emoji is more suitable for his current appearance. Of course, hearing his father's words, he probably guessed that they were taking the waterway. The Qinhuang test is divided into four levels, but these four levels do not have to be passed, but as long as you pass one level, you can reach the end, but these four levels are connected, and it is very likely that you will turn around in it and run to other levels.

The examiners are divided into four levels: gold, dark, water, and beast, which correspond to the metallic coffin level, the dark attribute poison swamp level, the water attribute cave level, and the beast attribute alien beast level. Before, Zhang Yuchang and others walked from the Golden Pass to the Beast Pass and passed through two levels, so they suffered heavy losses. Among the four levels, the water pass is relatively fantastical, and it is easy for those who are proficient in thaumaturgy to pass this level, so Li Han chose the water pass.

Before coming here, Ling Tan had already handed over some of the high-tech equipment of the scientific expedition team to Li Li, who would test the equipment. Li Moyun put on a black special combat uniform, put on a headset, changed into insulated leather boots, and had a ring-shaped high-voltage equipment on his wrist. Gloves made of a special material emit light in the dark, replacing light.

When the two of them were about to enter the cave, Li Yu took out two more synchronous video cameras, a small video camera the size of a round button, which could keep Li Liang and the two of them in the same field of vision, and he put the video camera on the left shoulder of the two to facilitate their movement.

Li Moyun walked in the front, and Li Han followed. At first, it was okay, there was a little sunlight, and Li Moyun was a little uncomfortable walking around, looking at the depths of the cave that was getting darker and darker in front of him, he seemed to be looking at the intestines of some animal. Li Moyun shivered from head to toe, indeed as Li Han said before, the closer he got to the center of the cave, the lower the ambient temperature inside it, just like the feeling of staying in a cellar in the hot summer.

Li Moyun observed the stone wall of the passage while walking, and Li Moyun's sudden voice startled Li Moyun, "Look at the surface of the stone wall is naturally formed, there are very few traces of artificial transformation, there are probably some things here that are not easy to deal with, you should be careful." ”

"Wow, uncle, you're going to scare me to death, you have to make a sound, say hello to me in advance." Li Moyun breathed a sigh of relief, patted his chest, and said into the communicator.

"It's not like you, how did you become so daring. Li Yu replied with a smile, which made Li Moyun extremely aggrieved, thinking to himself, "That's Ling Moyun, I have a Mao relationship, it's too difficult for me." ”

No way, Li Moyun is not very bold, but what he is afraid of is the unknown, and he is not very afraid of what he can see.

It didn't take long for the two of them to come to a spar-covered area. The terrain here is open, and in the dark underground caverns, there is still a faint light scattered around.

"Wow, old man, the stalagmites here can actually glow, it's too good, it's not scientific. Li Moyun couldn't help but admire when he saw the glowing crystal hanging upside down. In the video, Li Yu looked at the crystal and said with some puzzlement, "Indeed, looking at the appearance of the crystal, it resembles a crystal ore, and it is formed by water doping, generally speaking, it is impossible to emit light, even if it is a chemical product, but the crystal here is comparable to the brightness of a small light bulb, which is incomprehensible." ”

Li Han didn't approach these crystal mines, and pulled the hairy Li Moyun back, and said to him very seriously, "Stinky boy, don't touch the things here, this crystal should be a kind of amethyst, it is easy to break, and it will have a chain reaction, causing the water to rise here." What's more, this crystal also lives in symbiosis with a mosquito, similar to a lanternfish in the sea, which lures prey to take the bait. ”

"Huh~, what the hell, mosquitoes?" Li Moyun was very curious, he had never seen this kind of thing, and his curiosity was unprecedentedly high.

Li Han explained, "Pretty much, I've seen this kind of crystal under the East China Sea, and if it wasn't for your mother by my side, I don't know what would have happened." Okay, let's go" Li Moyun originally wanted to ask about his mother, but was interrupted by Li Han, it seems that he doesn't want to mention it for the time being.

After Li Handi deliberately reminded him, Li Moyun no longer touched the east and west, and it seemed that he still hated insects. The two of them cautiously walked through the crystal mining area to the depths of the stalactite-strewn cave. The sound of 'dripping' and 'dripping' water droplets echoed in the silent cave, and it didn't take long for them to come to an area where stalactites were becoming scarce. In the distance, Li Moyun saw that there seemed to be something hanging on the top of the cave, and Li Han saw those black reflections, his brows furrowed tightly, as if he already knew what it was.

When the two of them got closer, those black figures were all the corpses of people who fell in mid-air, and most of them were foreigners wearing camouflage uniforms. Originally, if it was just a corpse, Li Moyun's reaction would not be very large, but he saw that all the corpses had no skin and no moisture, which made him feel sick to his stomach immediately.

"What's going on, what about these people's skin? It's so dry that there's no blood. Li Moyun asked Li Han on the side with a disgusted expression.

On the other hand, Li Han was very calm, and his slightly frowning brows showed a slight resistance in his heart, "It should be done by a large bat, in the ancient south, people called this kind of bat a skin eater, because they don't eat meat, only suck blood and gnaw the skin of various creatures, so they were hunted down for a while, and it is said that they died a long time ago, but I didn't expect that there was still here." ”

"Ahh Li Moyun shook his head and swallowed, shining the light source at the hanging place above the corpse. After looking closely, it was found that the lower part of these corpses had been integrated into some crystal ore, and from a distance, it looked as if the corpse had grown out of the crystal ore.

"I'll go, I've really taken these damn things, the crystal ore here can also decompose corpses, it's too disgusting. Li Moyun found that the crystals here can melt people's bones, and when he thought of this, the feeling of appreciating these crystals suddenly disappeared, and his heart was full of disgust.

"Okay, don't look at it, we still have a task to complete, don't waste time on this. After Li Han finished speaking, he took the lead in walking forward, while Li Moyun straightened his collar, looked back and forth, and quickly followed.

After walking for a long time, Li Moyun felt that he stepped on the water, took a picture on the ground, and asked with a frown, "Old man, is there a water source here? Why is there stagnant water on the ground?" Seeing the water beach on the ground, Li Moyun was a little puzzled, but he didn't expect the water level to slowly rise as he walked.

"Old man, the water is rising. Li Moyun asked Li Han with some vigilance.

"Someone touched the ice mirror of the water gate and broke the ice in the underground river. 'Alas', trouble, stinky boy, it seems that some of you have suffered it, support the qi, otherwise we will be attacked by mosquitoes. Don't worry that where there are mosquitoes, the skin eaters don't dare to stay, go straight and don't care about anything. After Li Han finished speaking, he took out the Xun Lishu and asked Li Moyun to click on the center of the box until the aperture rose, he held the box in his hand and walked forward quickly.

Without saying a word, Li Moyun directly supported the momentum of the Imperial Qi Realm, enveloping the two of them in it. Gradually, the water level on the ground became higher and higher, and it was a little troublesome for both of them to walk. Suddenly heard a scream, it seemed to be a woman's voice, Li Moyun glanced at Li Han, Li Han nodded to him, and he hurriedly rushed to the place where the voice sounded.

When he got close to the source of the sound, he found several huge bats attacking a soaked girl, and it was thanks to this girl that she still had a bit of a foundation in her aura, otherwise it would have become a good meal for these skin eaters.

Li Moyun pulled out the folding knife on his waist, and slashed at one of the most ferocious skin eaters, the sound of 'stabbing' sounded, and the swinging folding knife had already cut off one of the skin-eaters' wings, and the others found the imposing Li Moyun, and hurriedly left the girl and flew away.

After Li Moyun had completely killed the skin-eater, he looked at the girl.
