Storm Dragon Veldora: Dungeon? What are you doing here?!

Black Dragon: Master?! Save me!

"What is this...?"

The boy sat in the center of a cave illuminated by glowing magic stones, staring at the enormous creature before him—the abyssal dragon.

Its scales shimmered with a deep purplish-black light, each one incredibly hard, seemingly capable of withstanding any attack;

Its eyes are like two gems burning with a deep blue flame, revealing an indescribable wisdom and an ancient aura;

When the dragon's wings were spread out, they almost covered the entire cave. They were not the membranous structure of ordinary dragon wings, but were composed of countless sharp bone spikes, each of which was like a carefully polished blade, radiating a cold light.

When it gently flaps its wings, the surrounding air seems to be torn apart, producing a deep roar.

If an average person saw it, their first instinct would be either to run away or to be instantly killed...

But now the dragon moved its tail and pushed a bunch of things that looked like fruit in front of the boy, Chen Hai.

"What's for today's food?"

"...!!!"

Upon being asked this question, the dragon nodded respectfully.

"Okay, I'll try it."

After saying that, Chen Hai picked up a food that looked like a combination of an apple and a watermelon.

With one bite, the sweet juice and pulp immediately fill your mouth.

"tasty."

"Roar……!"

After being praised, the dragon, which understood language, happily wagged its tail, like a husky receiving a reward from its owner.

After finishing the fruit, Chen Hai, feeling quite satisfied, returned to his previous spot.

It's time to look at today's data.

In the void, a panel appeared under Chen Hai's subconscious manipulation.

Name: Chen Hai

[Occupation: Dungeon Master]

Race: None.

[Strength Level: LV95]

[Magic: None.]

[Magic: None.]

[Inherent Skill: Dominator (Dominator of the dungeon, can gain all internal experience)]

Special Skills: Dimensional Assimilation (The dungeon connects to another world; depending on the degree of invasion, the dimension can be transformed into one's own territory, and power can be exercised), City Lord's Crown (Can subdue subordinates, turning them into city members, increasing experience points tenfold), As long as the city exists, one is immortal (as long as the dungeon exists, one is indestructible)

[City Member: None.]

[Connected dimension: The world of DanMachi.]

[Level of encroachment: 1%]

That's right, Chen Hai has transmigrated to the world of "Is It Wrong to Try to Pick Up Girls in a Dungeon?".

However, three days have passed since Chen Hai arrived here, and he remains stuck in this 'Abyss Floor'.

As for why...

Below the data panel is a so-called 'newbie task'.

[All features will be unlocked once the host level reaches 100.]

Thanks to this, Chenhai has been waiting.

In just three days, my level went from LV1 to LV95!

Because all battles that occur in the dungeon will be converted into experience points, which will eventually be absorbed by Chenhai.

I'm 5 levels away from LV100. I should be able to get it done today, right?

Ding--! !

Thinking of this, Chen Hai's thoughts were suddenly interrupted by a system sound effect.

The data panel changed instantly, and the level jumped to LV100.

[Level achieved, all features unlocked.]

"Are you finally here?"

As Chen Hai laughed, he noticed a new section appearing at the bottom of the panel—"Glossary".

Goodness, this system even has subsystems?

Chen Hai opened it and soon saw more content.

[Entry]

All-round genius (Gold) (Experience: 0/100): Can learn all magic and moves he has ever seen.

Dungeon Global Movement (Gold) (Experience: 0/100): Allows movement to any floor; after enhancement, it will no longer be limited to dungeons.

Unlimited Energy (Gold) (Experience: 0/100): Never tires; can rest or remain awake as needed.

The entries have five levels: gold, purple, blue, green, and white.

This shows that these are all quite good entries.

Thinking this, Chen Hai suddenly turned to the giant dragon in front of him.

"look at yours."

Having understood Chen Hai's words, the dragon obediently lowered its head.

The moment Chen Hai extended his right hand and touched the other person, he saw the basic data.

[Name: None.]

[Race: Dead Dragon.]

[Strength Level: LV120]

【Magic Power: 110000】

[Magic: Fire Breath, Flame Storm, Blazing Wings, Dragon Language Magic]

[Entry]

Greed (Gold): For each treasure collected, attack power increases by 1%, up to a maximum of 100%.

Sleeping Eye (Purple): While asleep, you can use the 'Insight' ability to perceive your surroundings.

Ancient Pact (Purple): This pact has a mysterious connection to this land; any act that damages it will incur the wrath of the Dead Dragon, increasing its destructive power.

Unlike Chenhai, the Dead Dragon's stats do not have levels.

As he was thinking this, he saw a new notification: "[Do you want to add the target as a member? You can then choose to copy their entries.]"

Chen Hai remained very calm in the face of this situation.

Before he was hit by the truck and thrown here, he had read a lot of isekai light novels and crossover anime with the theme of being transported to another world.

Of course, some of the themes are rather... well, you know.

Enough of the digression. Chen Hai, who was quite familiar with this function, did not immediately recruit the dead dragon as a 'city member'.

Firstly, the upper limit of the number of 'city members' is uncertain;

Secondly, there must be something even stronger in this 'Abyss Floor'.

Perhaps sensing Chen Hai's thoughts, the Dead Dragon curled up in frustration.

"Now that we've completed the mission and can freely teleport to different floors, let's go straight to the top floor and take a look."

Having been here for three days, Chen Hai still hasn't seen the world of "DanMachi".

Upon hearing this, the dragon raised its head.

"You can't do it."

Chen Hai waved his hand.

Bringing a dragon of a higher level than oneself to the upper levels would certainly cause a commotion.

Chen Hai has no immediate intention of revealing his identity.

Having said that…

"Every battle that takes place in the dungeon will become my experience points, so the adventurers from Orario who come to the dungeon are basically working for me."

For sustainable development in the future, it is necessary to think about how to turn those adventurers into our own 'laborers'.

You can use incentives to lure people in;

It can also be dominated by force;

But whichever method you choose, that's a story for another time.

However, just before setting off, Chen Hai suddenly realized that he had not been cautious enough.

Even if you have the "I am as long as the city exists" buff, which grants you immortality, you still cannot teleport after leaving the dungeon and may get into trouble.

and--

"I don't know how to upgrade this entry."

[Consume your level to upgrade the attribute level (level = your experience points)]

The system suddenly provided an answer.

Simply put, it means there's one more step in the process.

A battle breaks out in the dungeon—Chen Hai gains experience as a result—levels up—and uses the level to strengthen himself.

Why not just use experience points?

The grade is one of the standards for the strength of the connection between planes.

Upon seeing the second answer, Chen Hai finally understood.

Without continuing this 'exchange', Chen Hai went to the surface and his gaze returned to the Abyss Death Dragon.

The entry 'All-Round Genius (Gold)' allows Chen Hai to learn all the magic and techniques he has ever seen.

Since that's the case, let's just take advantage of the dead dragon.

But if I don't have magic power, can I still use magic?
