Nova silently read the notifications.

The next moment—

lightning exploded beneath his feet.

With a flash of blue light, he dashed toward the colossal gate standing before him. The massive doors that had remained shut until now slowly began to open with a deafening sound, shaking the entire dungeon floor violently.

Nova tightened his grip around the two longswords in his hands.

Although he had no idea what kind of monster awaited him inside, confidence still burned within him. Compared to when he first entered this cursed dungeon, he had grown unimaginably stronger.

This quest had pushed him into despair countless times but it had also become the greatest opportunity for growth he had ever received. And Nova intended to squeeze every last bit of value out of it.

With that mindset, he stepped through the massive gate.The room beyond was pitch black. Silent. But the moment he entered—

he felt it.

His senses had evolved far too much to miss something like this. A terrifying aura filled the entire boss room, so heavy with bloodlust that chills instantly ran down his spine. The pressure alone nearly froze his body for a moment. It felt overwhelming.

Oppressive.

As if death itself was staring directly at him from the darkness. Fortunately, the strengthened Demonic Aura inside him stabilized his mind almost instantly, allowing him to regain control of his body.

Even then— his instincts screamed at him violently.

Run.

Run away immediately.

Every fiber of his being warned him that whatever existed inside this darkness was far beyond anything he had faced until now.

”Oh?... A human brat possessing demonic aura?”

A dreadful monstrous voice echoed through the darkness, deep and heavy enough to make the entire room tremble slightly. The sound seemed to come from somewhere deep within the center of the enormous chamber, carrying a terrifying pressure that instantly made Nova’s senses scream in warning.

His body subconsciously tensed as he slowly took a few steps backward, tightening his grip around the longswords before speaking cautiously.

”W-who is it?”

The next moment, blue flames suddenly ignited one after another across the massive dungeon walls, illuminating the previously pitch-black chamber. As the eerie blue light spread across the room, a colossal figure slowly emerged from the darkness, and the moment Nova fully saw it, his breathing nearly stopped.

The creature was massive—easily over thirty meter tall. Its enormous wolf-like body was covered in thick silver fur marked with dark black stripes that resembled cracks spreading across steel. Every movement of the beast radiated terrifying power.

Its blood-red eyes glowed ominously as they stared down at Nova like he was nothing more than a tiny insect it could crush beneath its claws without effort.

The creature’s limbs were monstrously thick, packed with explosive muscles that looked capable of shattering mountains, while its enormous silver claws gleamed sharply beneath the blue flames, appearing sharp enough to tear through anything in existence.

Acidic saliva dripped continuously from its massive jaws onto the ground, melting parts of the dungeon floor with hissing sounds. Thick bloodlust oozed from its gigantic body like a physical force, making the surrounding atmosphere feel suffocatingly heavy. Even breathing near the creature felt difficult, as though an invisible predator was crushing down on his entire existence.

Nova instantly activated All Appraisal Eyes.

=================

[A colossal wolf-type monster carrying traces of Fenrir’s bloodline—the legendary Wolf of Destruction.]

[Possesses monstrous physical strength, terrifying agility, extreme regenerative abilities, and overwhelming predatory instincts. Its claws are capable of tearing through steel and stone effortlessly.]

[The pressure emitted from its bloodline alone is powerful enough to suppress lower-ranked beasts.]

Nova’s eyes widened in complete shock after reading the information. Fenrir... the legendary Wolf of Destruction from Norse mythology. A god-level existence he had read about countless times back in his previous world. And now, standing before him, was a monstrous beast that carried traces of that very bloodline.

Cold sweat slowly dripped down Nova’s body as he stared at the gigantic Moonclaw Tyrant towering before him. This thing was an A-rank monster... a creature completely beyond anything he had faced until now.

’What sort of fucked-up monster am I supposed to fight now...?’

”To think a puny human like you, who hasn’t even reached the Initial Breakthrough Stage, dared to kill all my subordinates... and now you still dare stand before me?” the colossal wolf spoke, its dreadful voice echoing throughout the massive chamber.

Every word distorted the surrounding air around its gigantic figure, carrying overwhelming pressure that shook the dungeon itself. Its blood-red eyes stared down at Nova with pure killing intent, as though looking at a tiny insect that had unknowingly offended a king.

”Do you not wish to live, human child?”

Nova’s eyes narrowed slightly after hearing those words. His first thought wasn’t fear—but confusion.

Initial Breakthrough Stage?

Before he could think further, the system instantly responded to his thoughts.

[Host, the Initial Breakthrough is the first major evolution humans experience after crossing Level 100.]

”Hm... so that’s what it is,” Nova thought inwardly. But honestly, he didn’t care much about it right now. Whether it was some breakthrough stage or not didn’t matter anymore. He had already survived nearly ten days inside this hellhole by constantly standing at death’s door.

Slowly lifting his head, Nova directly met the giant wolf’s terrifying gaze without showing the slightest intention of backing away.

”So what if I killed all your subordinates?” he spoke calmly, though his voice carried a cold dominating tone. ”And so what if I haven’t crossed level hundred yet?”

A faint grin slowly appeared on his blood-covered face as lightning flickered faintly around his body.

”I still dare to fight you.”

Then his eyes sharpened further.

”And for a wolf carrying the bloodline of a legendary beast like Fenrir...”

”You sure talk too much.”

”GRRRR... YOU DARE SPEAK THE NAME OF OUR ANCESTOR WITH YOUR FILTHY HUMAN MOUTH?!” the Moonclaw Tyrant roared furiously.

The entire dungeon shook violently from the sheer force of its voice. A monstrous wave of bloodlust exploded outward from the giant wolf like a tsunami, crashing toward Nova with enough pressure to destroy the minds of weaker beings instantly.

If it had been anyone else standing there, they would have collapsed immediately under that terrifying aura.

But Nova’s Demonic Aura activated instinctively, shielding his mind from the pressure while stabilizing his senses. Though the overwhelming bloodlust still made his instincts scream in danger, he remained standing firmly.

The giant wolf noticed this instantly.

Its enormous crimson eyes narrowed slightly.

”No more words...” the beast growled deeply while lowering its gigantic body slightly, preparing to pounce like an apex predator about to tear apart its prey.

”Today...”

”I will feast on your flesh.”

The next moment, the colossal wolf exploded forward with terrifying speed. Its gigantic claws shattered the dungeon floor beneath it as the thirty-foot monster rushed toward Nova with the intention of ripping him apart completely.

Nova activated every single one of his skills at once.

The next moment, lightning erupted violently around his body as his figure shot forward like a thunderbolt toward the incoming Moonclaw Tyrant. Both longswords in his hands became coated in crackling lightning, producing sharp screeching sounds as they tore through the air.

And then—

BOOOOM.

Nova’s swords collided directly against the gigantic claws of the Moonclaw Tyrant, creating a violent shockwave that blasted through the dungeon chamber. The ground beneath them cracked instantly from the impact, spreading massive spiderweb fractures across the floor.

But neither of them stopped there.

Again.

And again.

Earth-shattering clashes echoed throughout the dungeon as claws and blades collided repeatedly at terrifying speeds. Lightning exploded wildly around Nova while the gigantic wolf’s silver claws tore through the air like natural disasters.

”Hmph.”

The Moonclaw Tyrant snorted coldly while continuously exchanging blows with Nova . It was obviously far stronger physically, but after several clashes for few hours, even the giant wolf became slightly shocked.

Nova hadn’t even crossed the First Evolution yet—and he already possessed strength at this level.

Now the Moonclaw Tyrant finally began taking Nova seriously.

Its monstrous crimson eyes narrowed as killing intent exploded from its gigantic body. The colossal beast suddenly swung one of its massive claws toward him with enough force to kill him instantly.

This attack was completely different from the previous ones.

A strange oppressive aura coated the giant claw, distorting the atmosphere around it so heavily that even the surrounding space seemed to tremble under its pressure.

Reality itself looked as though it was shaking.

Nova’s instincts screamed in absolute danger.

”System! Quickly—put 30 stat points into Strength and 30 into Agility!”

The system instantly obeyed his command.

[+30 Strength]

[+30 Agility]

The moment the stat points were allocated, a massive surge of power exploded throughout Nova’s body. His muscles tightened violently while lightning burst around him uncontrollably.

Without hesitation, Nova crossed both swords in front of himself to block the incoming claw.

BOOOOM.

The impact was horrifying.

Even after strengthening himself, Nova still felt overwhelming force crash into him like a mountain. His body was blasted backward instantly as he shot across the dungeon like a cannonball before violently smashing into the massive dungeon wall.

CRAAACK.

The wall shattered behind him from the impact. Nova coughed out a mouthful of blood as pain exploded throughout his entire body.
