Many people speculate that there are 17 to 21 layers of underground cracks in the Earth Trace, 2,500 meters deep, crisscrossing between them, each layer is separated by dozens of meters or even nearly a hundred meters of rocks and soil, and each layer looks like an independent world. The six members of the expedition team walked along the way and found that it was hard to believe that it was part of the Yara World. In each layer, a large number of animals and plants that the outside world had never seen or even heard of, were found, and even the environment was very different from the environment in the Yara World.

Judging from the we have passed, this place is a paradise for arthropods. On the first floor, six people saw a large number of giant centipedes and horse land that were plated into a ball of entertainment, and many animals that entered the cave to feed from the open-air world of traces of the earth. These long giant arthropods have a large number of puddles in the second floor. The puddles are covered with algae, and large mosquitoes are buzzing everywhere in the sky. The ground and tunnels are covered with spider webs. You can often see spiders hiding in the dark crawling around. Seeing Freya is soft and almost dragged by Catherine to force herself to climb into the third floor.

When it comes to the third floor, the number of giant spiders is much smaller, but there are long bugs like stone strips everywhere. These bugs are only sixty or seventy centimeters long and feed on the moss and light-proof ferns in the cave. They are rare pure herbivores underground. They usually lie on the rock wall and stay still, and their shapes look exactly the same as the stones on the rock wall. Unless they touch them with their own hands, it is difficult to think that this is a kind of bug. Sometimes they pass through a tunnel. Suddenly, a large number of these bugs will fly up with a buzz. When they are disturbed, they will emit a large amount of irritating gas.

If you don't close your eyes in time, it will be as painful as pepper sprinkling into your eyes. Most of the giant spiders on the third layer feed on these rock insects. Of course, there are many other large bugs that don't have many characteristics in the recipe, even smaller spiders. However, on the third layer, these spiders also encounter terrible enemies. This layer is home to a bee insect, which also has a huge body of more than one meter long and often makes the same noise when flying as the millstone rotates. These bee insects also catch rock insects. But they prefer to catch giant spiders.

The spikes at the tail pierced into the spider's body will inject a numb venom. The spider's body will be completely paralyzed, and then the spider of the same size will be dragged back to the nest with its strong flying ability. Panis said that he had seen similar bees in the Sighing Swamp, but their size is more than five times smaller. The bees will lay eggs into the captive's body, and after the eggs hatch, there will be living food to enjoy. Since there are many ways to detour the third floor, the journey took more than eight hours. Along the way, at least thirty life-and-death battles between bees and spiders. Thirty battles each have their own outcomes, but in total

In other words, bees have an absolute advantage, with a winning rate even higher than 80%. These bees are obviously very interested in creatures of a certain size, not just spiders. They also include six explorers passing by here. Fortunately, they are always accompanied by huge roars and emit very high heat when flying. It is difficult to pose a threat to explorers. They are often split in half by Catherine before they get close. Their fragile defense is as thin as a piece of paper than the centipedes and horse land on the first layer, and they cannot cause any obstacles to Catherine's chopping.

Now, the second day after officially entering the underground crack of Earth's Trace, the group has exceeded the task. The first underground river that has entered and passed in advance is heading towards the fifth floor. Since there has not been any trace of spiders on this floor so far, Freya seems to be in a good mood, humming the folk songs near the Neutral Land in a charming voice, adding a bit of beauty and beauty to the boring journey.

"Well, there are not many spiders in the future." Ike was answering Panis's question: "It can't be said that there is no, but there are not many. But if you encounter a spider later, it will become quite powerful, both in terms of strength and speed, far exceeding the previous ones. By the way, I saw the existence of a spider at the end of the tenth floor. It was already a semi-god beast. It was entrenched in an underground hole on the tenth floor to feed on the surrounding creatures, and was one of the overlords of the tenth floor. If I hadn't found a path in time and crawled in and left its territory, I'm afraid I would have become one of the victims."

"There are demigods on the tenth level?" Panis raised his eyebrows and asked in surprise: "I remember you said that the more you go, the stronger the monster is. If there are demigods on the tenth level, then what monster will exist at the deepest point?"

"I want to know too." Ike's eyes flashed with yearning for unknown areas and desire to conquer the unknown: "The creatures of the mortal world, the demigods are already your peak, but what if there are creatures that can break this common sense below? However, the possibility of going on is not high. Several demigod explorers have fallen on the thirteenth and fourteenth floors. Unless there can be an expedition team composed of demigods with rich adventure experience, the number of people must be enough, maybe you can go deep into the world after the fourteenth floor. For example, the team of heroes who fought against the soul a hundred years ago is good. I heard that Kyle and Nellie have rich experience in exploring, and the others are not academic demigods. When they combine, their strength should be able to reach the 16th floor. Unfortunately, those people are important figures in various forces, and it is impossible to risk their lives to accept this proposal."

"It's really unlikely." Panis's smile was a little unnatural: "Those important people can accept sacrificing their lives for the safety of the mainland, but they may not 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 in is the greatest meaning."

"Okay, maybe you're right." Panis smiled bitterly, "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 of the few people is still a long tunnel. The characteristic of the underground world is that a large number of tunnels connect many huge holes together, so moving forward in the tunnel has become one of the most common things to do here. This tunnel is low and narrow. It can only be used for one person to bend down and walk inside. If Freya has not lost more than 20 kilograms during this period, it may be difficult to pass normally inside. At this time, Panis took the initiative to walk first, retreating from Catherine to the end, and after the tunnel was broken, the tunnel had reached the narrowest place, and everyone could only lie on the ground and crawl, but there is also an advantage here. Most dangerous arthropods in the underground world are relatively large in size and it is difficult to enter such a narrow space. Therefore, there is no need to worry about being attacked suddenly.

Underground adventures always bring some pressure to the heart, just like what everyone felt when crying in the cave before. But on the one hand, this place is because the cave is narrow and the light is sufficient, and the girls cannot feel the impact of darkness at all. On the other hand, unknown creatures can be seen everywhere here. The attention is attracted by the unknown at any time, so they don’t care about the depression and anxiety brought by the space.

"Is there any other creature worth noting in it?" Pennis was reluctant to discuss the heroes and asked in a different way: "Like creatures like the scorpion and the beetle in the entrance."

"There are thousands of insects living on each floor, and each one has certain dangers and needs attention." Ike replied: "But there are not many dangerous insects in the areas we need to pass through. Except for some powerful creatures wandering around, such as the beetle just now, most of the remaining ones are sociable creatures, which are truly sociable."

"Flock together?" Lina, behind Eke, asked curiously: "Are you living together like a spider and a mosquito on the second layer?"

"No. That's why I particularly emphasize that it is a real group living." Ike explained: "The above are just living together, and cannot be considered a group living. Real group living must be like most of the creatures on the fourth, fifth and sixth floors. A large number of similar creatures gather together, act together to rest like the same body, jointly foraging, hunting and building nests, and form a large-scale group together, so that they can be considered a group living."

"Well, it's just like bees from the outside?" Lina asked, "There are ants. They are all considered to be in groups."

"Yes, just like those." Ike nodded and said, "On the fourth, fifth, sixth and third levels, some creatures with super-individual strength, the rest of the overlords are group creatures, tens of thousands or hundreds of thousands gather together. No predator dares to provoke them easily. Many times they will attack predators in turn to compete for enough living space. Fortunately, the individual strength of the group creatures is not strong and has a relatively small size, which is not a big threat to those with shields."

"What are the characteristics of this layer of social creatures?" Panis asked, "What does it look like?"

"In this layer, the most powerful one we can encounter should be considered a kind of locust." Ike said: "It should be said that insects like locusts, but they are very small in size and do not like activities, so they usually don't encounter them."

"It's very small?" Panis laughed strangely: "About twenty centimeters?"

"Yes," said Ike. "It's of course bigger than the insects outside, but it's definitely a small insect here."

"Do they look very ugly, their bodies are brown, and they have two very obvious strong thighs." Panis asked, "There are brown wings behind them, their mouths are protruding outwards, and their vertical teeth are all?" Panis asked, "And there are many serrated teeth on their thighs, and their eyes are protruding outwards?"

"How do you know?" Ike's face suddenly froze and he said with a dry smile: "Did you see them?"
