The underground rift in the Marks of the Earth is not so much a cave as a huge world hidden underground, even if you count the first eight layers that have been basically discovered by explorers who love to explore from all walks of life, the area covered by them is close to a quarter of the area of the Yara continent, and this is only half or even a third of the entire underground world. If Ike's guess was not wrong, and the underground world was indeed larger than the first floor, then the total area of all seventeen or even twenty-one layers would already exceed the surface area of the Yala continent itself.

It is obviously not so easy to find a research institute of several square kilometers in such a huge underground system, although there is a range of about fifty square kilometers, but the sum of these fifty square kilometers of each layer is probably close to a thousand square kilometers, and these fifty square kilometers are not a smooth road, but an underground world connected by twists and turns and complicated paths, maybe if you miss a certain path, you will always miss the opportunity to find the research institute.

"Mr. Ike, I have a question now. Catherine gasped and asked, "If there is another situation where the path of this must be blocked by demonic beasts, do we have only one option: to break through head-on and disperse or kill the enemy?"

This is the fourth underground level, and the six people have just climbed down from the crack in the third floor when they see that the only passage is blocked by a five-meter-long beetle. The beetle was pure black, covered in a thick carapace with a shiny scarapace, a pair of long tentacles, and six short legs thick and powerful, covered with barbs, which supported its body steadily. At the position of its mouth, eight teeth as sharp as knives are closed from both sides to the middle, forming a terrifying mouthpart, and the girls have seen it bite off a hard rock with its teeth, just to devour some slightly smaller insects hidden behind the rock, such mouthparts, enough power to bite the head of any legendary professional directly, the girls are very skeptical, even with the shield on, is there enough strength to resist the bite of the beetle. Not only that, but when the beetle saw several members of the adventure group, it immediately let go of the insects that had not been eaten, turned its head to face everyone, and the carapace behind it suddenly cracked, forming a pair of wings together with the hidden wing membrane under the carapace, and actually flew on the spot, while making a buzzing sound of wings, and quickly launched a dive towards the girls. When the beetle flew in place, not only did it startle the girls, but everyone keenly felt that in this spacious tunnel, the temperature actually had a significant increase, and with the beetle taking off, the temperature increased by at least about five degrees. The sudden rise in temperature made the girls mistakenly think that this was only a fire-attribute demonic beast, but unfortunately, it was not a fire-attribute demonic beast, but a physically strengthened demonic beast, it didn't have any magic, but its own strength, especially the power of the mouthparts, had been exaggerated.

This was the first tough battle encountered by several people after going deep into the traces of the earth, and in the face of the enemies of the legendary rank, the girls felt that they had no way to start. The giant beetle has the hardest shell of the beetle, which jingles when struck by hand as if it were a solid piece of metal. Catherine tried to slash at the enemy's shell with her weapon, but with a crisp crash, the black carapace did not leave any scars, but seemed to provoke the opponent, causing the beetle to speed up even faster. Although Catherine did not use Dou Qi to strengthen when slashing, the powerful slash of a Legendary knight caused enough damage to split a piece of marble in half, but it did not have any effect on the carapace of the beetle, which shows how hard the carapace is.

In order to test the opponent's combat effectiveness, Catherine refused to be helped by others, and fought with the beetle alone for five minutes, during which she was almost injured by the beetle's wings, which were not smooth, but had a large number of fine serrations, which were difficult to spot without looking closely. Fortunately, when her wings approached Catherine, she instinctively sensed the danger, and unfolded her fighting shield in time to avoid serious damage to herself. After five minutes of entanglement, she finally found an opportunity to cut the beetle's body open from its relatively soft belly, ending its life. Of course, this fierce battle also cost Catherine a lot, and when she finally killed the beetle, because she stood under the beetle and cut open her abdomen, the green insect liquid sprayed directly on her body, leaving her all over her body soaked with fishy mucus, emitting bursts of unpleasant smell.

"Vivien, do me a favor. Catherine asked Vivian for help with a confused expression, and Vivien forced a smile and condensed a water balloon out of thin air, helping Catherine rinse her body little by little like a shower, until she washed the dirt through the armor.

"Most of the time, you can choose to take a detour. Ike explains, "A lot of the roads here are figured out, and when you can't get through here, it's easiest to take a detour from the side. However, in a situation like the one just now, if you need to go around, you need to retreat to the third floor, and then go around in a big circle and re-enter the fourth floor, which will take a lot of time, so in this case, it is better to kill or drive them away. ”

"Okay, I see. Catherine nodded and said to her teammates: "Everyone has seen the enemy's combat effectiveness, since this beetle can occupy the position of a predator in the fourth underground layer, it means that the combat power of most of the demonic beasts is relatively close to it, so if you have to fight in the future, everyone will work together to solve the other party as soon as possible." ”

"No problem, if you work together, you should be able to kill the monster as quickly as possible. Lina nodded and said, "But I found a very strange thing, since we came down to the underground world, the more powerful monsters we have seen are basically large insects, and there is no normal point of monsters, Mr. Ike, do you know why?"

"Didn't I tell you?" Ike widened his eyes and recalled carefully, as if he hadn't mentioned it, so he could only scratch his head in embarrassment: "After the seventh underground floor, it is difficult to see the traces of giant bugs, but before the seventh floor, the underground world is occupied by bugs, and this place can almost be said to be the kingdom of bugs." ”

"In other words, we accidentally broke into the bug hole?" Lina lamented, "I wonder if there is any way to reduce the chances of the bugs spotting us." On the third layer of the road just now, there were at least four cases of us racing against the bugs, and if it weren't for the wide range of perception of Pannis, who avoided the hunting range of the bugs in time, maybe we would have started a war with the bugs a long time ago. If there are other methods, such as turning off the lights, to reduce the chance of being discovered, I guess we can make it easier on the way. ”

"To correct it, we didn't carelessly, but we broke into the bug hole very carefully and meticulously. Pannis corrected harshly, "And don't you like bugs like Freya?"

"There are a few normal girls who like a bunch of bugs, especially ugly bugs of this size. Lina rolled her eyes, muttered a few complaints, and suddenly said to Freya, "Don't get me wrong, stupid, I thought of this because I hate bugs, and it's not for you." ”

"Whatever your reason, I'm afraid you're going to be disappointed. Pannis shrugged, turned off the shoulder light on his shoulder, moved a few steps sideways out of the team's light range, and said regretfully in the dark: "The strength of the light has a very small impact on the bugs, but it has a greater impact on us, after all, the dark vision of most bugs is stronger than Ike, and turning off the lights in the dark will only give the bugs more opportunities to attack us." ”

"Hey, that's a pity. Lina pursed her lips and shook her head, "Then it looks like we're going to have to move forward in the swarm." ”

"It's not that exaggerated. Ike explains, "One of the peculiarities of the bugs here is that they don't move in groups, they choose to live alone. Maybe it has something to do with their size, after all, they are so big, if a group of people live together, I'm afraid they can eat and wipe out the creatures of an area in the blink of an eye. ”

"And that's not all. Pannis said: "The existence of insect swarms is originally because the insects are too weak to protect themselves and obtain food, and now that they do not have this problem, there is naturally no need to live in the community." So, as you have seen on the road before, most of the insects live alone, at most two or three together, and sometimes they will even be wary of their own kind, so as not to hunt each other. However, the results you want to achieve are not necessarily achievable. ”

"Huh?" Freya and Lina paused at the same time, almost stopping: "Is there a way to get the bugs to take the initiative to avoid us?"

"There is a way. With a mysterious look, Pannis took out a bottle from his pocket and held it in front of him: "The best way to do this is this." ”

"Isn't this the slime you just collected, the beetle that the eldest sister killed?" Lina asked puzzled, "It looks disgusting, what are you going to do with it?"

"There are often some strange inductions between insects, and even if they are far apart, often one part of them can be very sensitive to find the other part of the bugs. "So some people have theorized that their bodily fluids carry some strange signals that can be transmitted far and wide anytime and anywhere," Pannis said. Ike and I confirmed just now that this beetle is one of the top overlords in this layer, and if we smear these bodily fluids on our bodies, even if it is just a little, the rest of the bugs will mistake us for beetles, and most of them will stay away. ”

"You guys stop and then we talk. Catherine and Ike's voices came from the front, "Better come and have a look." (To be continued.) )
