Once upon a time, there was a big hole in the world.

It was a large cave that could give birth to infinite monsters, which could be called a demon cave.

Countless alien monsters that poured out of the great cave once wrecklessly wreaked havoc on the surface, and their footprints swept through the forests, mountains, and even valleys, oceans, and skies, all over the world.

In order to regain their dignity, to regain peace, and to avenge their victimized compatriots, the Terrans crossed the racial barrier and began to work together to fight back against the monsters.

After countless years of struggle, under the leadership and active performance of the being known as "heroes" by later generations, the Terrans drove the monster back to the Great Cave that was the root of it, and built a fortress on top of this Great Cave.

This fortress is the labyrinthine city of Olali.

That big hole is the dungeon.

The dungeon is a labyrinth.

There's another world inside that's different from the surface.

In this world, there are countless floors.

Exactly how many floors, no one knows.

People only know that the environment and terrain of each floor of the dungeon are different, and the types of monsters are also complex and changeable, the deeper the layer, the more complex the environment and terrain, and the monsters will become more and more terrifying and powerful as the floor deepens.

In other words, people who are not strong will not be able to go far even if they enter the dungeon.

Even if it is the first layer that is closest to the surface, recognized as the safest, and the weakest monster, an ordinary person entering it, eighty percent of them will encounter life-threatening dangers.

Even those who have already received favors and have abilities will need a certain amount of courage and like-minded teammates to break through the dungeon.

Therefore, during the day, the square in front of the Tower of Babel gathers many adventurers who have received favors and come from various families who have registered in the "guild" that manages the labyrinth city and whose main job is to explore the labyrinth.

They will form teams and venture into dungeons in order to gain great wealth, fame and prestige in this "unknown" realm.

As for the night, it's usually not likely that adventurers will enter the dungeon.

However, in the middle of the night, a man entered the Tower of Babel, through the decorative door of the hall on the first floor, and followed the stairs along the edge of a huge opening, to the first floor of the dungeon.

The person who recklessly broke into the dungeon in the middle of the night didn't even have a decent piece of armor and equipment, and directly wore a civilian clothes with zero protection ability, grabbed a short sword, and entered here.

“————”

Boundless silence pervades.

Rig raised his eyes and looked ahead, and suddenly saw the roads that seemed to be underground tunnels that stretched out in all directions.

The walls and ceiling are a consistent light blue.

Terrain such as forks, intersections, and gentle downhill roads form neat roads at regular intervals.

There was no one else around.

At this moment, Rig stepped into a demon cave, an underground labyrinth, as he literally said.

"It's a bit like when I was trying to survive in the wilderness in the forest, and I accidentally strayed into a cave inhabited by bears."

Rieg was unusually calm, just walking in the cave at random, and the footsteps were clearly audible in the silence.

"Ho..."

"Ho..."

I don't know if it was attracted by Rigg's undisguised footsteps, and a faintly audible roar appeared one after another, hidden in the darkness.

Riege's eyes moved, his footsteps did not stop, only his gaze shot straight ahead, looking towards the end of the cave.

There, at a fork in the road, a pair of scarlet eyes lit up in the darkness.

The monster that lurked in the dark, waiting for the prey to come to the door, quietly appeared.

It wasn't until he got a little closer that he saw the monster clearly.

It was a labyrinth monster with a dog's head and sharp claws——— "kobold".

"Ho..."

With a wheezing breath, a kobold broke away from the group and walked out of the darkness as if impatiently.

It was thinner than Riege, uglier than humans, but full of violentness, and it was absolutely shocking for Rig, who saw the "alien" for the first time.

However, Rieger did not stop.

"Gah!"

As if seeing its prey coming to his door automatically, the kobold let out a sharp roar and pounced on Rig.

The vicious alien shape continued to expand in Rig's pupils, and the figure kept approaching.

"Whew..."

Letting out a breath of turbidity, Rig struggled to suppress his pounding heart.

This feeling———

"It's been a long time."

The corners of Riege's mouth were rarely outlined naturally.

Obviously facing danger, Rieg not only did not feel timid and afraid, but fell into an inexplicable state of excitement.

Thinking back to the beginning, when he left home for the first time, left his family's field of vision, and sought thrills outside for extreme sports, Rieger felt the same way, not only did not feel uneasy, but was inexplicably excited.

Maybe it's been numb for too long.

Maybe it's been too long.

Once too depressed, too restrained, Li Ge seems to have bottomed out, and things must be reversed, once he encounters something very exciting, the calm and composure that he has maintained in the past will suddenly reverse, and he will be so excited.

With this inexplicable excitement, seeing the kobold pounce on him, Rig did not stop and sped up his pace from beginning to end.

From walking to galloping.

From galloping to galloping.

——— run.

Rig launched a fearless charge towards the "unknown" that he had never seen before.

"Gah!"

The kobold immediately reached out with sharp claws and grabbed Rig's head.

In the next second, with a "bang", the kobold's claws landed on a short sword decorated with bells and whistles.

When Rig approached the kobold to the limit, he boldly raised his short sword and blocked the opponent's claw attack that poked into the head.

"Bang!"

The next moment, a muffled sound exploded.

But it was Li Ge, who set up a short sword to block the kobold's attack, and with his free other hand, he clenched it into a fist and slammed it into the hideous dog's head.

"Gah!"

The kobold let out a howl of pain, and his thin body was unable to block the impact of this punch, and he was directly bounced to the ground.

"Ho!"

"Gah!"

Seeing that his companion was unfavorable, he was punched by the prey waiting for him, and the rest of the kobolds hiding in the darkness couldn't sit still, and all of them rushed out at once and rushed towards Lige.

Seeing this, Li Ge's heart beat faster, and the excitement in his heart also increased, and he felt that his whole body was full of strength and strength.

This is a phenomenon caused by the stimulation of adrenaline.

The scene in front of him reminded Rieg of the time when he was surviving in the wild in the forest.

At that time, there was also a time when Rig was ambushed by wolves at night, and like this, he was pounced on by multiple wolves.

Remembering the events of that time, Riege's body naturally moved.

Although he traveled from a world without any mystical and supernatural powers, since he had played wild survival and extreme sports, Rige's original physique was naturally good.

Although the original owner is also a guy who does not learn and has no skills, as a peasant child who has worked in the countryside, he is not bad in terms of physical strength and physique.

This puts to good use the martial arts skills that Rig had learned in order to defend himself and the knowledge he had learned in his self-defense classes.

So, in the face of the head-on attack of several kobolds, Rig chose the most appropriate approach at the moment.

"Gah?"

The kobold, who was wailing and being beaten to the ground, found that he had suddenly been lifted.

Rig grabbed the leg of the kobold who fell to the ground, shook it violently, and threw it at the kobold group that was rushing towards him.

"Bang!"

There was another muffled sound, and in the howl of the kobold, the first two kobolds were hit by their oncoming companions.

The kobold's group immediately plunged into chaos.

The kobolds in front of them were smashed to the ground one after another.

The kobold in the back tripped over the kobold who rushed in front, and lost the momentum of the charge for a while.

And at this time, Rig moved again.

He automatically launched a charge, rushed to the nearest kobold, and while the other party was at a loss and fell into chaos, the short sword in his hand burst out and stabbed it in the head.

"Quack, ahhhh

With a terrible scream, the kobold fell to the ground with blood splattering all over his head.

A drop of blood stained Rieger's face with a cold glow of his eyes, looking like a merciless demon.

"Gah!"

"Ho!"

The kobolds seemed to be enraged, and one by one they trampled on their companions and rushed towards Rige.

In this regard, Li Ge directly grabbed the kobold who fell to the ground and died, carried its thin body, and used it as a meteor hammer, slashing the tiger and the tiger, whirring, and sending the kobold who pounced one by one.

In his hand, the dagger is rarely used, and is only used to block when the kobold's claws and fangs reach his body, or else he will only use it when he needs to deliver a fatal blow, stabbing his sharp blade into the body of his enemy.

Such a battle lasted for an unknown amount of time.

"Poof!"

Soon after, Rig stabbed his dagger into the chest of the last kobold, piercing his heart.

The last kobold fell, announcing the end of the battle.

Silence returned to the dungeon.

Rig stood in the middle of a kobold's corpse, looking at the blood and monster wreckage all over the ground, and then at his blood-stained hand and short sword, the blush on his cheeks was particularly glaring.

"Not enough..."

Rieger suddenly whispered.

"It's not enough..."

A heart that beats faster cannot be calmed.

The gushing blood can't be stopped.

The excitement of emotions swelled in his chest, making Rieg whisper from the heart as if he had vomited out all the depression caused by the unfreedom of the past.

"It could have been more violent..."

Following his inner whisper, Rig completely lost his former politeness, like a berserker chasing something that he couldn't see, and took steps deeper into the underground labyrinth.
