The approaching "things" have been confirmed, and they are all skeletons that move on their own, ostensibly human, very similar to the undead warriors depicted in many game comics.

The only difference may be that there is no so-called "soul fire" in their eyes, and there is no light in them.

They are just simple human skeletons, completely deprived of the breath of life, and the bones have decayed and blackened, but I don't know why they are not completely decayed. Dressed in ancient armor and holding weapons and shields in their hands, they approached step by step.

In between actions, the noise of metal grinding from their heavy armor made one wonder if their old bones were going to crush themselves.

But although the actions of these skeleton warriors were not fast, they were very heavy, as if they were dragged down by the burden on their bodies, but none of them were crushed by themselves, but they approached slowly, teamed up with the dense "companions" around them, and formed a deadly formation-

It's not very refined, it's not very ingenious, it's not a tactical formation, it's just an endless sea of skeletons!

At least from the passages in all directions, there are skeleton warriors, and in the ancient ruins of this black underground space, only the light of flashlights shines through, and it is really not a good experience to see such a scene everywhere.

Bang! Bang! Bang!

Earthquake-like shaking came and went, and more than a dozen AIBO-type killer Graeme marched in an orderly manner around them, and this group of dog-headed robots was three meters tall and extremely powerful. There was no need for any tactics at all, just constantly walking, and crushing countless skeleton warriors.

They also raised their arms and pounded the ground as they went, making a rumbling, dull vibrating sound.

Although those skeleton warriors used the Skull Sea tactic, they were still ants after all, and it would take a long time to bite an elephant to death.

What's more, there is not only one "elephant" here, basically those skeletons have been trampled and smashed in tens or hundreds of quantities to be able to leave a few scratches on the steel shell of an AIBO-type murder Graeme.

Deep or shallow.

In the middle is the giant canine-like robot, which holds two huge arms, holding everyone up, and moves slowly forward under the support of the dozen or so smaller "little brothers" around it.

But because of its huge size, it takes more than a dozen steps for ordinary people to catch up with each other, so although the movement is slow, the speed of movement is definitely not too slow, basically equivalent to the speed of ordinary people trotting, and it can be maintained all the time.

……

……

"I always feel that the situation is very delicate now, as if I am playing a game......

Sanzenin Nagi knelt down, looking at the sea of skulls below and the small robots that were opening the way around him, muttering with a complicated expression.

Behind her was a careful guard, for fear that her master, a young housekeeper who accidentally fell from a high altitude. After that, there is a stupid trio such as Miki Hualing, who look completely heartless, each holding a flashlight and shooting in all directions.

And Egremiya Isumi sat kneeling in the palm of the robot like Yamato Nadeshiko, looking at the back of the blonde double-ponytail girl in front of him, and his expression seemed to be very worried.

At a very young age, she often accommodated Nagi's interests, played with her, and helped her out. It's not just because of friendship, it's also because of guilt and compensation — she did something wrong when they were both very young.

Although she was well-intentioned and didn't want to see her friend immersed in grief all the time, her behavior didn't change anything, it only made her friend sadder even more. At first, hope was given, but only to find that there was nothing to be done, so that unnecessary hope turned into more despair.

What a cruel thing this is, Egret Palace Isumi knows it well.

Therefore, she has always carefully guarded the happiness of her friends, and tried her best not to let her friends continue to get in touch with the field of extraordinary knowledge. It's just that the current situation is not something she can decide, she can only say that the situation is stronger than people.

Glancing at the seemingly endless sea of skeletons around them, Egret Palace Isumi sighed, when they left the confines of the dungeon and entered the confines of this ruin—even if it was only the edge, they might have been doomed to not be able to turn back easily.

They're actually moving deeper now.

Because when they tried to return the same way before, they always encountered all kinds of landslides and collapse accidents, and a large number of skeleton warriors were also forcing them into the darkness in the depths, no matter what, they had no way to return the same way, and after tossing for an hour-

Basically, there is no road left.

In this regard, the ghost priest's explanation is that there is a strong will in the deep demon cave, there is no doubt that it is "alive", although it does not have more intuitive power, but it can have some incredible ability within the scope of this ancient ruin.

Father Regiosta even suspected that he had died inexplicably under his own poisoned arrow, and it was also for such a reason that he refused to admit that it was because he was already old and demented at the time, and he could not remember what happened.

Therefore, in such a situation, he can only go into the depths, anyway, someone says that he can get out no matter what, and he will resist when the sky falls...... And it seems that he really has the qualifications to withstand the sky falling.

……

"So, what's in there?"

Mu Xiu asked with a slight squint at the ghost priest on the huge arm of the robot on the other side. However, although it has not been made into a super-spirit body and used as a supporting material for possession and integration, the ghost priest is obviously not a person who knows how to read words and feelings.

This is true before and after death.

Therefore, Father Regiosta just looked at the huge robot that everyone was in, and thought unwillingly: "It's even more handsome than my robot......

"Of course! I bought it with all my mother's savings!! The violent nun glared angrily at Mu Xiu.

Muxiu: "......"

Now the dozen or so AIBO-type killer Graeme around him were completely controlled by Mu Xiu's manipulation of the radio waves, and the huge canine robot under his feet was also dragging cable plugs behind him, and it was obvious that Mu Xiu was also supplying power, so he was naturally under his control.

Although she knew that this was the best thing to do, Miss Nun's mood was certainly not much better.

Cracking sound!

A flash of electric light flashed on Mu Xiu's forehead, and several people next to him felt a flash of a powerful static electric field, and the hair on his body showed signs of standing up. Father Regiosta was even more unbearable, only for a moment, his figure blurred, as if he was a hologram that would dissipate at any moment.

In the face of such a direct threat, the ghost priest immediately started a serious painting style:

"I don't really know what's inside, in fact, I've never been into the depths, and I only got to the edge with spells and holy water, and now you're in a position that exceeds the distance I explored at that time......"

"What's the use of you?" Mu Xiu was a little disappointed.

Father Regiosta hesitated for a moment, then hesitated:

"There's one place that might be worth noting...... I heard the roar of some beast coming from the depths, and I don't know if I heard it wrong, but at that time, it felt like my soul was really shattered, and I only faintly heard a trace of it......"

The rumbling sound continued, and at this time, everyone's feet were violently shaken.

This is due to the fact that the space in front of it has become low, and the giant canine robot is only able to bend its body. However, everyone has already had experience along the way, so there is no problem, and occasionally someone who is unstable is also pulled by the person next to him.

“……！！”

Suddenly feeling a tightness in his shoulders, Mu Xiu glanced back, only to see Gui Daisy behind him looking straight ahead, his expression stiff, and his shoulders trembling slightly.

The pink-haired girl's hand grabbed his shoulder so hard that he felt a dull pain in his shoulder blades when he pinched it, and the adult's other hand also used the wooden knife Masamune as a crutch, nailing the other end to the metal shell of the robot's palm under his feet for stability.

It's really pitiful, both afraid of heights and afraid of ghosts, now Gui Daisy is in the air at a height of seven or eight meters, but below is a dense sea of skeletons, the so-called dilemma can be said to be vividly reflected in her.

"Daisy-san, do you want to sit down?" Mu Xiu sighed and asked.

"No, no, no...... It's a little difficult...... ...... can't scare me" Her voice was trembling, almost crying, not convincing at all.

Mu Xiu couldn't help but look over to the other side, and found that Takako Itsushima was already lying on Mizuho Mizuho's lap with her eyes in circles, and it seemed that she couldn't recover before she got out of the range of the Skull Sea.

"Ahem, okay, but I want to sit down and take a break, Daisy-san is bothered to accompany me, right?" Mu Xiu said with a smile, and pressed the girl's shoulder with his backhand without saying anything, and pressed her hard to sit down.

Obviously I'm afraid of heights, why are you still so strong!

“……”

glared at someone very angrily, but Gui Daisy let out a long sigh of relief, and did not continue to resist, but just knelt down and sat down with a proper posture, and did not let go of the palm that was tightly gripping Mu Xiu's shoulder-

She didn't see the perspective directly below now, and she couldn't feel the presence of height, so she was a little more relaxed.

But she didn't fully recover right away, you must know that her legs are still weak, and she is completely insecure psychologically if she doesn't grasp something.

Mu Xiu didn't care, he carefully sensed the front, and then with a wave of his hand, relying on a powerful magnetic field, he attracted a certain weapon in the sea of skeletons below in the air and flew into his hand.

It was an old spear, but it wasn't rudimentary. The head of the spear is made of a piece of pure iron, in the shape of a broad leaf, with a pointed top, and seems to have been deliberately designed to pierce deeper, but the head is mounted on a spear shaft made of ash.

Whether it is an iron spear head or an ash wood spear shaft, there are several simple and strange strange symbols engraved on it, which have not been worn by the years and are very clear.

"Sharp, piercing, and ...... durable" Muxiu children's shoes are no strangers to those symbols, and the main effect of their combination can be read almost instantaneously.

After all, it is only a combination of several rune runes, and the basic rules used in the rune sequence are not particularly advanced combination formulas, at best, it is the difference between addition and subtraction, and it is also a single-digit calculation, which naturally does not make it difficult for him.

Casually put this spear gun aside, Mu Xiu absorbed a few more spear guns, and after careful inspection, he found that the rune inscriptions on it were exactly the same, and the number of runes, the specific type and the location of the inscription were all exactly the same.

These seem to be standard weapons of ancient rune craftsmanship?
