While Others Cultivate, I LVL UP In My Sleep Using The Dungeon System

{Ding, the host has now entered a Sub-Dungeon}

"AAAAHHHH" screamed Adam as he slid down the long hole, as his back scraped against the hole of the wall. ​​

However, as he fell, he suddenly felt the sensation of being sucked into another space, that he felt when entering the dungeon, and when he felt that he had landed on land, opened his eyes.

Looking around him he was in a dimly lit den of some sort that had 3 cave-like entrances before him.

{Ding, in this Canidae Sub-Dungeon the host will have to rely on luck, power and determination to reach the end where there is a reward.

Each entrance leads to a different stage and after completing 3 stages, the host will reach the end of the Sub-Dungeon and can return to Floor 1.

After each stage completed, the host will reach a checkpoint that he will be transported to the next time he enters the dungeon if not completed in one try.

However, the entrances are randomised each time and the host cannot complete it by trial and error} the system announced.

Hearing the system's words, he was both anxious and excited.

"Are you ready" said Adam to his Leporidae.

Receiving a squeak and a nod from the small white snow hare, Adam took a deep breath and walked towards the different entrances.

Without hesitating, knowing that it would only waste his time and make him second guess himself, Adam picked one without overthinking it.

"I will go right this time" he decided.

Lifting the small white snow hare in his palms, despite him feeling slightly nervous around it especially with its now reinforced and strengthened claws, Adam walked into the right tunnel.

{There is no need for the host to be scared of his Collector Skill summons as they will completely submit to you with your current charisma being at 5 points. However, as they reach a higher level of strength they will become harder to deal with. But for the current moment, the host does not need to worry and can retract the summon in the worst-case scenario in the future} the system reassured.

As he entered the tunnel there was a sudden and loud thud from behind him that shook the ground.

Adam turned to there being a large wall blocking off his retreat, but instead of being worried, Adam continued forth with anticipation of what was to come.

As he continued forwards, there was an end of the tunnel and an open and empty area.

Adam thinking that he had lucked out and chose the easiest route ran straight into the open area, but as soon as he entered the tunnel was closed off in the same way the entrance was.

{Stage 1 - Defeat 5 LVL 5 Arctic Foxes} the system announced.

As he heard this, similar to a game, 5 quite small white and grey foxes spawned out of thin air before him.

"Shit" he exclaimed as he jumped back to make some distance between them and have his back to the wall so he couldn't be sneak attacked.

"I really am lucky especially when my summon is a hare and am battling arctic foxes" he mumbled sarcastically.

The Leporidae Summon in his hand seemed to be offended by his joke and seemed to hate being looked down upon as it jumped out of his palms and glared at the fox beasts.

[It seems my summons really do have a consciousness] he noted seeing how it reacted.

Leporidae Summon

LVL: 5

HP: 90

Strength: 10

Speed: 21

Intelligence: 13

Special Traits - Camouflage

Types Integrated - Snow Hare

Enhancements - Strengthened Claws

Seeing the stats of his Leporidae Summon that he had fed all the claws of the snow hares he defeated, Adam was confident in its ability.

Arctic Fox

LVL: 5

HP: 130

Strength: 14

Speed: 15

Intelligence: 13

Then seeing the statuses of the arctic foxes, Adam was unsure who would win in a battle but seeing their intelligence being on par knew it would be close.

Canidae and Leporidae beasts are both very intelligent, but almost every time they shared an ecosystem, the Leporidae beasts would be prey to the Canidae beasts.

The fox beasts seemed to be programmed to be hostile towards Adam and his summons as they growled furiously at them and made Adam wonder who or what exactly was the Dungeon System and where it came from.

However, in the current situation, Adam didn't have the time to think to himself and got ready and prepared for battle.

With his fists clenched he slowly approached the growling beasts.

They were in a quite small enclosed room formed of some kind of rock and was like a small cave that was around 10 metres in length, and it being closed off made it so that there was no escape.

It was somehow mysteriously dimly lit without a light source, yet after everything he had seen, Adam just shrugged it off as normal and focused on the situation ahead of him.

The Leporidae Summon instead of waiting for orders suddenly burst off its feet towards the closest arctic fox.

Adam not wanting his summon to get injured, which would waste his MP, chased after it, but the difference in speed was too large.

After hunting in the dungeon a few times now, Adam realised that his MP wasn't only for using skills but also represented the energy in his body and his overall stamina and when it was lowered he felt that his body would become sluggish and tired.

The fox beasts seemed to be stuck in the position they were in, but as soon as Adam's summon attacked, what was holding them back seemed to be released.

The seemingly weak snow hare with its fast speed lunged at the closest fox beast and slashed with its dagger-like claws and gauged out the beast's eyes mercilessly and jumped backwards in retreat.

Howling in pain the fox beast despite being blinded charged towards the snow hare relying on its strong sense of smell as the rest of the beasts followed after him furiously.
