"Udaeus"

Amidst a deafening roar that shook the air, Leo finally saw the full form of the enormous creature before him.

It was a skeletal monster, entirely black, with its lower body buried underground and its upper body nearly ten meters tall, resembling a gigantic, Earthborn.

Its forward-leaning, curved spine had countless vertebrae trembling, undulating like waves with a will of its own. Its head had two horns that looked like those of a demon. The black bones gave one the feeling of being sucked in just by looking at them. Its whole body had a sharp luster that was both eerie and dangerous.

At the center of its enormous skeletal body, in the chest area, an abnormally large Magic Stone was exposed to the air, protected by thick sternum and ribs. The huge crystal, radiating a dazzling blue-purple light, was like a heart, but it was not as bright as the small crimson flames burning deep in the dark eye sockets of the creature.

It is Udaeus, the floor master of the 37th Floor.

With its jaws agape, it faced the skeletal monsters around it that were howling like newborn babies. After a while, the crimson flames flickering in its eye sockets turned as it looked at the figure standing not far from it.

There was a palpable sense of ferocity and malice emanating from it.

"Ugh----!"

The girls standing at the entrance of the cave tensed up involuntarily when they saw this scene, as if they were the ones being stared at by those strange eyes.

Ais drew her silver saber and stared intently at the enormous skeletal monster, while Lefiya Viridis unconsciously took a step back, her pretty face turning slightly pale.

About a month ago, they watched Leo challenge the newly reborn floor master in the same way, supporting him.

However, unlike last time, this time Leo is facing Udaeus, who is classified as level 6, instead of Goliath, Goliath is classified as level 4.

Leo challenges Goliath, yet the women remain confident in supporting him, watching the battle with composed expressions, certain that they can intervene in time to protect Leo no matter the situation.

But when their opponent changed to Udaeus, they lost that confidence.

That was a formidable enemy that even they dared not face alone; a terrifying existence that even if they were to take action, they dared not say they could stop in time.

Therefore, Ais, as well as Tiona and Tione, all gripped their weapons tightly and assumed fighting stances.

However, Udaeus did not set his sights on the women outside the cave, but only on the insignificant ants who dared to stand before him.

J

Roar oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh!"

With a roar that shook the air, Udaeus slowly raised his twisted, black, shiny bone arm and unleashed a fierce attack on Leo, who stood before him.

"Boom!"

The moment the massive, twisted bone arm fell, Sonic Boom resounded.

"[ -Comet Dash.]"

Faced with this devastating attack that could crush the air, Leo did not hesitate to cast a flight spell.

The opponent is Udaeus, the floor master of the 37th Floor, who possesses potential abilities that may even surpass Lv.6. A single blow could severely injure or even kill a level 5 adventurer. If Leo, a mere level 4, doesn't unleash all his trump cards right from the start, then forget about fighting, even surviving for a little longer will be an impossible task.

Therefore, Leo activated his flight magic without hesitation. His entire body was enveloped in dazzling Starlight, and he soared into the sky like a comet, avoiding this terrible attack.

"Boom!!!"

The enormous skeletal monster slammed its paw into the ground, instantly shattering it into pieces.

With a deafening roar, the ground collapsed as it kicked up thick dust, and countless cracks spread outwards from the surrounding area.

Having dodged the attack, Leo transformed into a comet once more after ascending into the air, hurtling towards Udaeus at an astonishing speed and tearing through the atmosphere.

His target was the enormous Magic Stone exposed to the air.

Ordinary monsters hide their Magic Stone deep inside their bodies, but Udaeus, due to his physical structure, has no flesh or internal organs to hide his Magic Stone, so he can only protect it in his sternum.

The Magic Stone is the core of a monster's existence. Even if Udaeus is a terrifyingly powerful floor master, he will still die once he loses his Magic Stone.

Therefore, when faced with a formidable enemy like Udaeus, almost all adventurers would do the same thing: try to attack its chest cavity directly, break its breastbone, destroy the Magic Stone located there, and thus defeat this overly powerful monster.

If someone can still resist targeting their weaknesses after they've been exposed, they can hardly be considered a qualified adventurer.

As for the fact that the enormous Magic Stone could fetch an astronomical price if sold on the ground, that's not something worth considering in the midst of the life-or-death battle on the upper floors.

If your opponent is a floor master whose potential ability even surpasses Lv.6, and you still consider whether to keep their Magic Stone and take them to the surface to make a fortune, then you are either incredibly strong and don't take Udaeus seriously, or you are a complete idiot driven by pure greed.

The former might exist, but Leo is currently only Lv.4, is definitely not among them. The latter usually have to pay the price for their greed. Not only do they not make any money, but they may also die on the spot. Leo naturally does not want to become such a fool.

Therefore, Leo not only went all out from the start, but also attacked the Magic Stone, which was his weakness, without any hesitation.

Unfortunately, if Udaeus's Magic Stone were so easy to attack, it wouldn't be so feared.

"Boom!"

Just as Leo transformed into a comet and hurtled toward Udaeus's chest, the ground that it had smashed into with countless cracks suddenly began to rise again.

The next second, a huge, pitch-black pillar burst through the ground and shot out from underground.

The pitch-black pillar resembled a spear reaching upwards, a dark sword mountain, or an inverted stake. The commotion it created as it swept through the darkness was considerable. With a thunderous roar, it broke through the air and shot towards Leo.

Without a second thought, Leo abruptly stopped, freezing the speeding comet in mid-air and avoiding the oncoming sword mountain.

Sword Mountain then slammed heavily against the wall on the other side of the cave, shattering the wall into pieces.

The power of that strike was in no way less than the force that Udaeus had unleashed when he slapped the ground earlier.

Leo's expression immediately became even more serious after dodging the extremely sharp attack.

These inverted piles, continuously shooting out from the ground, were Udaeus's most prized weapon.

When Udaeus is born, it usually only has its upper body above the ground, while its lower body is buried underground, looking as if it has not completely broken free from the "egg shell" from which it has hatched. This makes it basically unable to move, and even turning around is not easy for it. However, its lower body is not buried underground in vain.

Strictly speaking, Udaeus did not actually have a lower body.

It is like a huge tree with its massive roots deeply embedded in the ground, its lower body already transformed into countless parts, spreading out into the underground of the Throne Room, ready to transform into inverted pillars and shoot out from the ground at any time.

The fallen stakes are spread throughout the entire cave, and their attack range covers the entire battlefield, so even if the user cannot move, they can easily attack enemies located in any corner of the room.

It can be said that this entire vast "cave" was Udaeus's territory, a minefield riddled with countless landmines.

Once you reach Udaeus, even the entrance and exit may be blocked by the dark mountain of swords. The Bone King will not allow the enemy to escape until the slaughter is over, so even a large raiding party cannot defeat this inflexible floor master in one go. Instead, they may be toyed with by him.

Using the force of the falling pillars, it can prevent enemies from getting close and from escaping easily. If anyone dares to approach it, they will be attacked continuously by this sword mountain.

Now, Leo is facing this kind of weapon that combines offense and defense, a terrifying weapon that made Udaeus famous in the Lower World.

"Boom!" "Boom!" "Boom!" "Boom!" "Boom!"

As explosions echoed through the air, one after another, jet-black stumps combined to form a sharp sword mountain, which broke through the ground one after another and shot out at a terrifying speed, attacking Leo. Leo, who had transformed into a comet, could only dodge left and right in mid-air to avoid this endless attack. The jet-black sword mountain also crashed into the surrounding walls, destroying them.

The comet, like a shooting star chasing something, sometimes turns left, sometimes right, sometimes rises, sometimes dives, leaving its brilliant Starlight to streak across the sky, leaving long tails of light that create a dazzling spectacle.

During this process, the comet continued to accelerate and change direction, making the dark sword mountain try to pursue it countless times, but it was always unable to hit its opponent.

"--Roar oh oh oh oh oh oh oh oh oh oh oh oh!"

Seeing this, Udaeus was instantly enraged. He swung his massive bone arm, creating a whistling wind, and repeatedly struck the flying comet. However, the comet nimbly dodged the blows and could not hit him at all.

"[Light of Heaven, Sword of Stars.]"

Leo, who was flying back and forth among countless sword mountains, also performed Parallel Chanting and launched his proud attack magic.

"[Meteor Dance]!"

A thick meteor shot out from the rotating magic circle and headed straight for Udaeus.

"Bang!!!"

Udaeus's eyes burned with strange flames, yet he fearlessly threw a punch that struck the incoming meteor with a deafening roar, colliding violently with it.

In the surging shockwave, the thick meteor was blasted apart by Udaeus's punch, scattering into countless stardust fragments, leaving not a trace.

This floor owner's power is so great that he can even suppress Leo's firepower.

"[Meteor Dance]!"

"[Meteor Dance]!!"

"[Meteor Dance]!!!"

Leo, however, calmly chanted his spell again, launching meteors one after another, each one thicker than the last, displaying overwhelming firepower.

"--Hengwei, Udaeus accepted all comers without fear, his fists flying in unison, blasting the incoming meteors one after another, displaying extraordinary strength."

This made Leo realize something.

"This battle is likely to be quite difficult."
