The speed at which the cold iron cooled was not slow, but after entering the crypt for about ten minutes, the burning sensation in his chest turned into a warm feeling. It's just that it's still a little difficult to remove it before it's completely cold. And because there is no connection to the wizard's vision, the networm can only carefully follow Bakham at the end of the line. It's not a good position, and the person at the end of the line is often the first choice for sneak attackers, who are often difficult to spot even if they are missing due to the lack of companions behind them.

Somewhat unexpectedly, however, there are some natural light sources in these passages. It was a fluorescent flying insect flying around the team, and at first Leon thought it was the Green Child, but after a few seconds of careful observation, the knight realized that it was some insect with a hollow body and a faint glow from it.

"Rotting fireflies. The crow reached out and grabbed one of them, crushed it cruelly on his fingertips, and said lightly.

Leon and Bakham, who grew up in the north, were unaware of the creature, but the knowledgeable killers and mercenaries, as well as Kirly, who had come from the southern cities, were no strangers to the rotting fireflies. The larvae of this insect are found in rotting food, and now these are their adults in the air. It is an extremely short-lived creature, and once it spreads its wings, it is not long before it dies. Folk legend is that these little creatures are spirits born from food that has never been properly kept, and that they will dissipate when they come into contact with sunlight. Wizards who are proficient in biological structures know that the lifespan of rotting fireflies is extremely short, only because they have no other organs in their bodies except for a simple reproductive system after becoming adults, and they starve to death after exhausting their physical strength.

"Why are you here? Aren't the nezumi vegetarians?" said the mercenary, a little puzzled, although these little guys did solve a lot of problems for her, but thinking of the witch Kuira's control over insects, she was afraid that the team had fallen under the watchful eye of the other party.

The wizard waved his hand slightly, signaling to everyone not to worry. "Cheese used to say that the nezumi here are different, and maybe they gathered food while trying to change the recipe. Don't worry, the structure of these rotting fireflies is too fragile to carry any magic. They are the living dead who are doomed to death. The crow shook his palm, letting the insect debris remaining on his fingertips fall, and then said silently, "Who isn't?"

The number of rotting fireflies slowly increased as they went deeper, and they seemed to be flying from the same direction, and after a brief discussion, several people decided to reverse the search for the birthplace of the rotting fireflies. It was supposed to be a granary or something else for the Rat People in Vale, and it shouldn't be too far from the main body. On the way, they inevitably passed by an uninhabited outpost, but there was no trace of insect activity in the building compared to the one where Leon and Buckham had encountered the giant ants. They even found some food at the outpost that they didn't have time to eat.

"Judging from the bite marks, it's indeed a rat man, but..."The Blood Lion picked up something that looked like dry food on the earthen platform, it was a faint green with a little fluorescence, far from the food in the eyes of ordinary people, but it did have tooth marks on it, and there were leaves on the earthen platform instead of plates.

Qili took the unidentified object from the knight's hand, she blinked, and then actually took a small bite from the other direction! The others were all surprised when they noticed her behavior, only the cursed crow impatiently snatched the object, pinched it off with her fingernails, crushed it, and put it under her nose to smell it. "The powder of many mushrooms, as well as some moss, is generally harmless to humans. Of course, taste damage is not ruled out. ”

By the time the wizard analyzed the ingredients of the nezumi food, the reckless witch was already throwing up in the corner. "It tastes like salted horse manure. Kiri commented, wrapping the object in leaves and hanging it carefully on her belt, "Peg must try it." "It looks like if she can get out of here, then poor Peg will inevitably be bullied again. Fortunately, no one in the team paid attention to this little episode, and even after Qili's nonsense, their tense nerves were slightly relaxed.

"Let's move on when you're rested, the number of rotting fireflies is much less. I'm afraid I'll get lost in the tunnels if I delay any longer. The Demon Spawn said, leaning against the exit of the outpost, crossed his arms and looked at the path that led to the depths, where there were as many as three branches. Fortunately, the rotting fireflies that are constantly flying out have become reliable beacons. Otherwise, it would take a lot of time just to find out these passages. However, at this time, the rotting fireflies that flew out one after another had a tendency to decrease, and given that it was not known how many such forks in the road would have to pass, Kalus proposed to step up.

The passage after passing through the post is much wider than before. Although the nezumi can walk on all fours, it is clear from this that they are still used to walking like humans, and the width of the three passages is large enough for adults to pass through. Seeing this, the crow also put away the metal ball from the heart of the darkness, and there was no need to widen the passage here, and the deeper it went underground, the more compact the structure built by the rats, and the rash use of the power to move the earth could cause the collapse of other spaces and cause unnecessary trouble.

Leon was at the front of the group after gaining Dark Vision, and the Demonborn was a few paces away from him. The reason for leaving a distance is to prevent the blood lion from being implicated with the people behind him when he falls into some trap, and it is also to reserve space for Leon to deal with the enemy. Moreover, such a distance of a few steps was as non-existent to Clarus, and it did not affect his speed at all to support Leon.

"It's such a wonderful structure, we've gone so deep into the ground, and we don't feel like we're out of breath at all. How do these nezumi do it? The Raven breathed hard into the air of the passage, which was mixed with the smell of earth, but it didn't stop it from bringing life to people. Such a magical underground building design, let alone ordinary humans, even dwarves or wizards dare not guarantee that it can be built. You know, so far, the sorcerers have not seen a facility or hole specifically for ventilation, and the rats have solved the most troublesome problems of underground buildings almost by virtue of their talents.

This made the gray-robed wizard think that if such a race could slowly increase in numbers, then in time, the title of Children of the Mountains might change to their heads. At this time, the cursed crow kind of understood why Cheese wanted to protect these rat people so much, they were a new species, and the possibilities were endless. And thinking that his transformation of Jerry might also be involved in the origin of this species, the sorcerer suddenly felt that the nezumi didn't seem to be so ugly anymore.

"Be careful, we're close. Leon gestured in sign language to the killer behind him. In front of him was a pit leading directly below, from which the rotting fireflies flew. This message was passed through the team one by one, and as the commander of the operation, the wizard quickly gave instructions to enter the room below.

One by one, the members slipped through the craters, and the ground below was not very deep, and judging by the improvised escalators built against the walls, the nezumi also entered and exited the room this way. If all the nezumi buildings that the previous few people had seen could barely accommodate a team, then the size of this warehouse could be described as huge. In front of the entrance, the top of the room forms a curved dome upwards, which is at least four meters high. In addition, the oval room is large enough to afford the name of a warehouse, and the footsteps on the ground can cause a slight echo.

"Guys, I think we overlooked one thing earlier. Just as everyone was looking around the room, the knight at the front of the line suddenly said, "Have you ever wondered why those rotting fireflies are leaving here?"
