Silver Dragons are spawning in this dungeon!

After that battle, both the dragon race and the human empire were severely weakened.

Various dragons suffered heavy casualties, and even the legendary dragons of the five colors came to help in the later stages of the battle.

Since then, the Dragon Clan and the Casa Empire have completely broken ties, and they still frequently launch small-scale battles against each other.

The Kingdom of Red Copper also disappeared completely, and all the Red Copper Dragons migrated to the territory of the Brass Dragons, forming the Copper Domain together with the Brass Dragons.

It was from that time onward that all the dragons on the continent of Oris were completely united and formed the Dragon Federation.

The Bronze Domain is one of them. The other metal dragon kingdoms have been renamed: the Gold Dragon is now the Gold Domain, the Silver Dragon is now the Silver Domain, and the Bronze Dragon is now the Bronze Domain.

Of the five colored dragons, only the blue dragons formed an organized Blue Domain.

The remaining black and green dragons, led by the red dragon, formed the evil realm, a chaotic and savage land.

As for the White Dragon...

Nobody wants to play with an idiot.

In the world of heavy metal dragons, the iron dragon reigns supreme, forming the Iron Realm.

Rare dragon species, such as the Rainbow Dragon, are scattered throughout various dragon domains.

The Koso Hills are the border region between the former Copper Kingdom and the Casa Empire.

Since that traumatic event, few people or dragons have come to explore this place.

As for why the Copper Dragons had to relocate their entire clan, it was naturally because of the forbidden alchemical equipment used by the Casa Empire.

The pollution has rendered most of the Copper Kingdom unsuitable for life, turning it into a forbidden zone. Even the dragon's stomach, capable of digesting anything, cannot digest the polluted soil.

The area was desolate, which is why it became a buffer zone between the Dragon Federation and the Casa Empire.

Even today, eight thousand years later, in the Koso Hills, far from the epicenter of the forbidden weapon outbreak, life is gradually returning.

The Casa Empire had not yet issued any instructions, but the Adventurers' Guild was already eager to act, offering substantial bounties to drive adventure groups to embark on adventures.

To probe the attitude of the Dragon Federation, and to investigate the specific situation of the Copper Nation.

This laid the groundwork for the empire to launch another war or plunder land in the future.

Ries received information that the location of this mission might hide an undeveloped underground city, and the mission objective was to find this underground city.

A preliminary assessment of the underground city was conducted to determine its potential for development and utilization.

Reis's goal this time is not just to find this dungeon; he wants to possess it. The reward boss that appears when it is first discovered is usually at the entrance.

He wants to defeat this boss and then obtain the reward.

After completing his advancement to swordsman, he went to his family to fulfill his three-year agreement. That year, he was expelled from his family for coveting his father's concubine!

Thirty years east of the river, thirty years west of the river, never underestimate Lei Si's poverty!

Once he becomes an eighth-level professional, he will be able to arm wrestle with his father.

Reis grinned maliciously as he looked at the stone gate embedded in the mountainside, its ancient patterns gleaming in the air.

With a wave of his hand.

"Brothers, charge! Open the entrance to this dungeon!"

"The first one to open it, I'll reward him with five gold coins!"

Gold coins have very strong purchasing power; one gold coin can support a family of three for a year's basic food and drink.

The forty-odd people behind him, upon hearing Reis's words, also displayed their unique abilities.

Demolition experts used bombs to force open the door, alchemists searched for mechanisms, and mechanics drilled holes in the mountainside next to the stone gate, preparing to find another way...

Inside the Boss's room.

Hilo felt hungry and stopped playing around with Novi.

We need to find a way out quickly, but currently there is no way out of the surrounding circular boss room; only the way we came is left.

The stone door that we came through had closed automatically when we entered, but it reopened after Hilo defeated the Slime King.

In Hiro's inherited memories, such a reward was enormous, second only to the rewards of the bosses on the last few floors, and being located on the first floor of the dungeon, it could only be a pioneer reward prepared for the excavators.

Reward the first creature to discover the dungeon.

Hilo suddenly realized a problem: this underground city had clearly never been discovered before, and no humanoid creatures had ever tried to conquer it.

and so……

I've never heard of a dungeon that can be opened from the inside!

In other words, there is no mechanism that opens from the inside out!

Hilo and Novi also checked every inch of the entire boss room.

There was no hidden compartment triggered at all.

Does this mean we're stuck in the dungeon?

He really doesn't want to eat slime every day!

Hilo thought to himself.

Just as Shiloh and Novi were leaning against the wall, feeling dejected and somewhat listless.

The Reiss Adventure Team at the entrance of the dungeon has made a major breakthrough!

The alchemist proved superior, discovering the hidden mechanism to open the dungeon.

"Commander! Commander Reis! I've activated the mechanism!"

The alchemist shouted at Reis.

"Good job, kid. I'll give you five gold coins when we get back after the mission."

There's really no problem with doing this. If the money is paid in advance, then people will be hesitant and timid about the tasks that follow.

Reese walked over and, without hesitation, pushed the lever.

The entire mountain shook violently!

Hilo and Novi, who were in the boss room, both felt the violent tremor.

What happened?

What changes have occurred in the underground city?

Does the dungeon have a mechanism that detects the death of the gatekeeper boss and automatically opens the dungeon?

wrong!

Hilo suddenly realized that the dungeon wouldn't open on its own, meaning it was outside at this time.

Just then, someone discovered this underground city!

"Novie! Get ready! Charge out!"

"Some creatures have opened the dungeon! They're coming in!"

Currently, most humanoid beings on the continent of Oris view dragons as if they were treasures.

Once lone fledglings like Hilo and Novi are discovered, hordes of humanoid creatures will inevitably flock to them.

The gates to the underground city slowly opened, and a ray of sunlight shone into the city.

Reis, carrying a greatsword, stood at the very front of the stone gate.

Dust was swirling around, making visibility poor.

Suddenly, just as the door opened wide enough for the three of them to walk side by side, a sword light flew out from the darkness and headed towards Reis.

Just as Reis raised his arm to block, two silver shadows flashed past above his head.

Reis was momentarily stunned; he had never heard of a dungeon boss being able to escape from the dungeon.

What was that thing just now? He didn't even have time to stop it.

The sword, which was invincible on the first and second floors of the dungeon, only managed to scratch the skin on Reis's arm in the face of his life level.

Hilo's current physical strength is roughly at level three, and with his magical abilities, his challenge level could reach level four.

In addition, the spell casting speed with no cooldown can be increased by another level.

As a veteran professional, Reis has a life level of 7, which translates to at least level 6 in terms of challenge level.
