"No, I must go back to the ground tonight to rest......" Nilou woke up and only felt that her energy was at most half recovered, and by the way, she had back pain.

Paris, who is used to a bad sleeping environment, complained: "What, it's a gorilla, and it's still so squeamish." ”

"Huh~? Again, who is a gorilla? Nilou held up her long-handled tomahawk, which didn't match her small size, and the frightened Paris ducked behind Ban, "...... Sorry, class. ”

"Slow, slow! Don't get me involved with an apology! Ben struggled to push Paris forward behind him.

Old man Laban smiled, and even he felt a little lighter when he saw the energetic interaction of the juniors: "It's just that a proper rest is for a safer and more efficient exploration, and I think it's a proper choice to return to the ground every day or two to rest...... Besides, we should also sell the antiques we find to exchange them for weapons and equipment, and replenish food and medicine. ”

At the very least, a weapon with demon-breaking attributes, a tattered silver sword is also acceptable, he doesn't want to be a super god of swordsmanship but be hung up and beaten by an incorporeal monster that is immune to pure physical damage.

"And camping tents and kitchenware!" Nilou raised her little hand to add.

Paris was speechless, "Hey, do you really think we're here for an outing?" ”

The shift in charge of bookkeeping and procurement took this need to heart, and patted Paris on the shoulder, "Considering that the underground ruins are much larger than expected, and we have Nilou in our team, we can make a profit with tents and kitchen utensils." ”

“…… That's right. "It's just that I always feel that the atmosphere is not right, and there is no tension.

The long handle of the tomahawk slammed to the ground, interrupting the two of them and saying, "Hey, what do you mean by defaulting to letting me carry my luggage!" ”

"Huh? It's just right. ”

"The power warrior doesn't carry luggage, so let's have two speed fighters on their backs?"

Needless to say, the pair's natural answer angered Nilou, and there was another fight.

Resuming his exploration, Ben uses the lockpicking skills he has honed since childhood to open an iron door, Laban keenly sees a breeze blowing through a cracked wall, and Nilou uses her tomahawk to break through the wall to find an iron ore path that has not been set foot on by other explorers.

Ignoring the iron ore exposed at the end of the tunnel, eliminating a group of monsters who were holding a bonfire meeting, and obtaining a few pieces of equipment from the corpses of the explorers that were not in the flow but slightly stronger than they were wearing, the group exited through the normal entrance and exit of the tunnel, and found themselves on a rock face near a large underground lake.

It is not clear whether it was done by ancient people or monsters, there are two passages on the rock wall, one high and one low, and looking along the passage from afar, you can see several caves on the rock wall, and it is estimated that one of the caves is connected to the ancient residential area above.

Ben walked to the edge of the tunnel and shouted, "Hey, look over there!" ”

"I've seen it a long time ago, the skeleton of the dragon, and I can't take it away." Paris didn't have a good airway.

If it weren't for Qiuna's current slumber, he would definitely try to find a way for Nilou to move the keel, and antiques are worth no material.

"It's not! I mean, at the bottom, explorers on the island in the middle of the lake are battling out an army of monsters! Let's find a way down to help! ”

》》》》》》》

With magic stones with exorcist power to drive away low-level monsters, two beds in the piggy bank, two small earth houses shaped with earth magic, and water elements lurking in the river to guard them, Lyle and his party got a high-quality sleep effect, and even slept a little too much, and breakfast became lunch.

Originally, because Fran was born with a talent for making dark dishes, Lyle planned to rely on the shelf-stable accessories in the Flying Pig Piggy Bank, and Kilia, who learned of the situation, applied for a cooking job and made a delicious lunch that made Miss Maid embarrassed...... To this end, Lyle also officially sent out an invitation to work as a maid, of course, with a clear and firm reply of refusal.

The group walked along the widest passage of what was probably the 'main road', and soon came to the entrance to the staircase that had been opened by the adventurer who had gone ahead, but had been re-locked, and quickly followed the bloodstain to find two adventurers who had treated themselves with emergency wounds and eventually died of blood loss.

"Something doesn't seem right, this man's wound was caused by a spear." Kiria frowned.

"It doesn't have to be infighting, it's a fact that the monsters in this ruin have their own culture, and it's not surprising that they will use spears as weapons." Lyle, who knew what Kiria was worried about, spoke, but his attention fell elsewhere, "...... I'm more concerned about the treasures they don't want to throw away when they die. ”

One adventurer is holding a giant egg to death, and the other has several ancient coins, a magic key, and a bone fragment in his backpack.

"People die for money, birds die for food, boring." Kiria said coldly.

"In other words, it's something that even they know has that value." Lyle was the first to pick up the giant egg, he didn't see the reason from the surface, and injected magic into the egg, some strange reactions, whether it could hatch again is not clear, but at least it was not a rotten egg, put it in the piggy bank first.

Kilia blinked, even though she had seen Lyle pull out the bed, kitchen utensils, and food from the Flying Pig piggy bank last night, she still felt that this so-called 'prop for the most basic application of space magic' was amazing.

…… If you can get such a convenient storage prop, it is not impossible to consider being a half-moon maid......

"Bones, broken bones." Lyle picked up the treasure in another deceased's backpack, and always felt like he had seen this thing somewhere.

Fran couldn't help but sigh, "It's impossible to tell which part of the bone is such a big bone, what kind of huge creature it is?" ”

"Huge...... Isn't that right? Alerted by Fran's unintentional reminding, Lyle had an idea and quickly took out the tools and potions from the piggy bank.

“？” Fran is a well-behaved maid, and Kiria is not a mouthy woman, quietly watching as Lyle scrapes off the bone meal for experimentation.

"Sure enough, it's a dragon's bone...... And it's a very powerful dragon bone, and the color of the potion has completely turned blue. "Lyle, who once made dragon bone weapons for the warriors of a western island country, naturally studied the characteristics of dragon bones," that is, the dragon egg just now? ”

The dragons of this world are not extinct, but their scarcity is a fact, and they mainly live on a certain island nation in the west, and it is difficult to find them elsewhere.

"Dragon egg, isn't this an ancient relic that has been sealed in the dust for many years? Even reacting to magic just now? "Franton was incredible.

Lyle casually stuffed the keel fragments into the piggy bank, and said helplessly: "Who knows...... Magical biology has always been the subject with the most research projects and the slowest progress in the Academy, let alone the dragons that have never had a living sample to refer to. ”

“…… Hurry up and see what's going on behind that door. Kiria urged.

Lyle naturally had no opinion, took the magic key he had just received and opened the locked door, only to find that it was a staircase going down, and after a few steps, he found corpses in a place, both monsters and humans. It is impossible to tell exactly what happened, and the order of occurrence of 'death of a companion' and 'the lock of the gate' is reversed, and the nature of the matter is completely different.

"Someone is fighting from afar!"

"Young master, there is a sound of battle!"

Kilia and Fran said at about the same time, the former rushing down the stairs first, and the latter staying where he was, waiting for orders.

“…… Have it? "Born with an excellent physique, it is not as good as a person who has specialized in cultivation, and Lyle, who can't hear the so-called 'sound of battle' at all, muttered two words, and also ran down the stairs, and almost tripped over the corpse, but fortunately, Fran was quick to grab him in time.

The first thing that catches your eye is a keel hundreds of meters long, and the staircase exit is about the middle of the keel neck. The answer to why the dragon bone fragments in the backpack have better attributes than ordinary dragon bones, the standard body length of ordinary dragons recorded in the literature is about ten meters, and magical creatures generally follow the rules of the largest and most powerful.

Turning his gaze downwards, at the bottom of the semicircular space, the underground river that flows down from above accumulates into a huge lake. There was a small island in the center of the lake, and there were some torches on the small island, and it was barely possible to see the adventurers fighting with the monster army, but it was not clear which side had the advantage, the distance was too far.

"Oh~ I can hear a little bit of fighting here!" It so happened that some unruly genius magician used a very noisy lightning magic.

"That kind of thing doesn't matter at all, okay! We're going to find a way to go over and help! Kiria glared.

"Yes, yes~ Don't worry, leave the big scene to me~" Lyle put his right hand around Fran, stretched out his left hand, and pulled Kilia, who was not paying attention to him, into his arms.

"You-"

The three flashed onto the dragon's skull.

“——！？” Kilia's words weren't spoken.

"Stay here and don't run around." Lyle let go of the two and flew towards the island in the lake. (Recommended reading: Reading Files 2013)
