Many people speculate that there are seventeen to twenty-one layers of underground fissures in the Earth, two thousand five hundred meters deep, crisscrossing each layer, separated by rocks and soil tens of meters or even nearly 100 meters deep, and each layer is like an independent world. Along the way, the six members of the expedition found that it was hard to believe that it was still part of the Yara world, and that in each level there would be a large number of animals and plants that had never been seen or even heard of by the outside world, and even the environment was very different from the environment in the Yala world.

Judging from the four floors that have passed through now, this is simply a paradise for arthropods, in the first layer, the six people saw a large number of giant centipedes and horses coiled into a mass to entertain themselves, and there are many animals that enter the cave from the open-air earth trace world to feed, these long giant arthropods, there are a large puddle in the second layer, the puddle is overgrown with algae, the sky is full of large mosquitoes buzzing and flying, the ground and the tunnel are full of cobwebs, and you can often see spiders hidden in the shadows crawling around, and Freya is soft when she sees it, and she barely climbed into the third layer by Catherine's hard drag。

By the third level, the number of giant spiders was much less, but there were long worms like stone bars everywhere. These insects are only sixty or seventy centimeters long, feed on mosses and light-sheltering ferns in burrows, and are a rare pure herbivore. They usually lie on the rock wall and stand still, the shape looks exactly like the stone on the rock wall, unless you touch it, it is difficult to think that this is a kind of bug, sometimes through a certain tunnel, suddenly a large number of these bugs will fly up with a buzz, when they are disturbed, they will spew a lot of irritating gas, if you don't close your eyes in time, it will be as painful as pepper sprinkled into your eyes. Most of the giant spiders in the third layer feed on these rock bugs, but there are many other large bugs that don't have many characteristics in the diet, and even other smaller spiders. However, in the third layer, these spiders also encounter a formidable enemy, which is inhabited by a species of bee-like insects, which are also more than a meter long and large, and often make the same noise as a millstone when it turns. These bees also catch rock worms, but they prefer to catch giant spiders, whose tail spikes pierce the spider's body and inject a paralyzing venom that paralyzes the spider's body, completely paralyzing the spider's body, and then relying on their strong flight ability to drag the spider back to the nest. According to Pannis, he had seen similar bees in the Sighing Swamp, but they were more than five times smaller, and the kind of bees would lay eggs into captives, and when the eggs hatched, they would have live food to eat. Due to the fact that there are more roads around the third layer, the travel time is more than eight hours, and there are at least 30 life-and-death battles between bees and spiders along the way, and there are 30 battles with their own winners and losers, but in general, it is still the bees that have an absolute advantage, and the victory rate is even higher than 80%. These bees are obviously interested in creatures of a certain size, not only spiders, but also the six explorers who pass by, but fortunately they always fly with a huge roar, and they also emit high heat, which is difficult to pose a threat to explorers, and is often split in half by Catherine before they can get close, and their fragile defense is as thin as a piece of paper compared to centipedes and horses in the first layer, and it is not able to hinder Catherine's slashing at all.

Now, it is the second day of officially entering the underground rift of the Earth Scarf, and the group has overfulfilled their task, entered the fourth layer ahead of schedule and passed the first Damned Underground River of the fourth layer, and is heading towards the fifth layer. Since there were no spiders on this level so far, Freya seemed to be in a good mood, humming a folk song from the vicinity of the Neutral Land in a charming voice, adding a touch of beauty and brightness to the boring journey.

"Well, there aren't many spiders left for the rest of the journey. Ike was answering Pannis's question, "I can't say no, but it's not much." However, if you encounter a spider in the back, it will become quite powerful, both in strength and speed, far exceeding the previous ones. By the way, the deepest I saw the existence of spiders in the tenth layer was the last, it was already a demigod beast, entrenched in an underground cavern on the tenth layer and fed on the surrounding creatures, and was considered one of the overlords of the tenth layer. If I hadn't found a trail in time to get into it and leave its territory, I'm afraid I would have been one of the victims. ”

"There are demigods on the tenth layer?" Pannisy raised his eyebrows and asked in surprise: "I remember you said, the further down the demonic beasts, the stronger the strength, if there are demigods on the tenth layer, then what monsters will exist in the deepest depths?"

"I want to know too. Ike's eyes flashed with yearning for the unknown and desire to conquer: "Mortal creatures, demigods are already your apex, but what if there are creatures below that can break this common sense? Unless there can be an expedition team composed of all demigods with rich experience in exploration, the number of people must be sufficient, maybe they can go deep into the world after the fourteenth layer, such as the team of the heroes who fought against the gods a hundred years ago, I heard that Kyle and Nelly are both experienced in exploration, and the others are not academic demigods, and their combined strength should be able to break through to the sixteenth layer. It's a pity that those people are important figures in various forces, and it is impossible for them to risk their lives to accept this proposal. ”

"It's really unlikely. Pannis's smile was a little unnatural: "Those important people can accept sacrificing their lives for the safety of the mainland, but I'm afraid they won't accept coming here and risking their lives meaninglessly." ”

"How can it be said that it is meaningless. Ike said dissatisfiedly, "Exploring and conquering this world that no one has ever set foot on is the greatest significance." ”

"Well, maybe you're right. Pannis smiled wryly, "But I don't think they think so." ”

"That's why I said it's a pity. Ike sighed and shook his head regretfully.

The location where the few people are now is still a long tunnel, and the characteristics of the underground world of the Trace of the Earth are that there are many huge cavities connected by a large number of tunnels, so advancing in the tunnel has become one of the most common things to do in this exploration. This tunnel is low and narrow, and can only be used by one person to bend down and walk in it, and if Freya has not lost more than 20 kilograms during this time, I am afraid it will be difficult to pass normally in it. At this time, Pannis took the initiative to take the lead, from Catherine to the end of the break, the tunnel has reached the narrowest place, everyone can only crawl on the ground, but there is also a benefit here, most of the dangerous arthropods in the underground world are relatively large, it is difficult to enter such a narrow space, so there is no need to worry about being suddenly attacked.

Supposedly, underground adventures will always bring a certain amount of stress to the heart, just like everyone felt in the Weeping Cave before. But on the one hand, because the cave is narrow and the lights are sufficient, the girls can't feel the impact of the darkness at all, and on the other hand, there are unknown creatures everywhere here, and their attention will be attracted by the unknown at any time, so they can't care about feeling the depression and uneasiness brought by the space.

"Are there any other notable creatures in the fourth level?" said Pannis, reluctant to discuss the heroes, digressing the subject, "creatures like the scorpion and the beetle at the entrance." ”

"There are tens of thousands of insect species living on each floor, and each one has a certain danger and needs to be paid attention to. Ike replied, "But there aren't many dangerous bugs in the area we need to pass through." Except for some powerful creatures roaming around, such as the beetle just now, most of the rest are social creatures, in the true sense of the word. ”

"Gregarious?" Rina behind Ike asked curiously, "Is it like a spider and a mosquito on the second layer?"

"No, that's why I emphasize that it's really a social dwelling. Ike explains, "The ones above are just living together, not in groups. True social dwelling is like most of the creatures in the fourth, fifth, and sixth layers, where a large number of creatures of the same kind gather together, act together as one entity, rest together, cooperate in foraging, hunting, and building nests, and form a large-scale group together, so that it can be regarded as social dwelling. ”

"Well, it's like bees from the outside world?" asked Lina, "and ants, they're all social residents." ”

"Yes, just like those. Ike nodded and said: "On the fourth, fifth, sixth, and third floors, except for some creatures with super individual strength, the rest of the overlords are social creatures, tens of thousands and hundreds of thousands of them are gathered together, and no predator dares to provoke them easily, and many times they will attack predators in turn to compete for enough living space." But fortunately, the individual strength of the social creatures is not strong, and the size is relatively small, which is not too much of a threat to us with shields. ”

"What are the characteristics of the social creatures on this level?" asked Pannis, "what does it look like?"

"At this level, the most powerful thing we can encounter should be regarded as a locust. "I think it's like locust-like insects, but they're all small and don't like to move, so they don't usually come across them. ”

"Very small?" Pannis's laugh was odd: "About twenty centimeters?"

"Yes. Ike said, "Of course it's bigger than the insects outside, but it's definitely small here." ”

"They are not very ugly in appearance, their bodies are yellowish-brown, and they have two very pronounced strong thighs. Pannis asked, "And there are tawny wings on the back, the mouth is bulging outward, and there are vertical and horizontal teeth?"

"How do you know?" Ike said with a dry smile on his face, "You saw them?"

"Heh, heh, heh. Pannis also laughed dryly and said, "Obviously, they're in front of you, and they don't look very friendly." (To be continued.) )
