While Chen Hai was negotiating with Loiman Mardil in the lounge, a phantom-like figure was moving in a dark corridor beneath the Adventurers' Guild.
He was clad in black, wearing black gloves intricately carved with patterns. Because of his appearance, some Guild staff referred to him as 'Ghost.'
And now, the man in black ascended a spiral staircase to the upper floor, opened a mechanism known only to him, and finally emerged from an opening on the rooftop.
His name was Fels, originating from a great magic nation. In the past, he was a 'Sage' who had pushed the development ability 'Mystery' to its extreme, successfully creating the 'Philosopher's Stone.'
Centuries ago, while wandering Orario, he was taken in by Uranus and became his personal mercenary.
Fels had now received orders to investigate the 'Dungeon Lord' who had appeared at the Adventurers' Guild headquarters.
According to the intelligence he received, Uranus believed that the Dungeon was undergoing an anomaly.
If it was not investigated and resolved in time, it was highly possible that the terrible event of many years ago—the Dungeon monsters invading the surface—would repeat itself.
It was known that even today, monsters that had escaped the Dungeon and reproduced still existed in various parts of the world.
Fels walked to the edge of the rooftop, looked down, and saw the lit-up lounge.
The Dungeon Lord… that's what the Adventurers' Guild staff called the other party.
Eina, as the first person to interact with him, believed that this identity was most likely true.
Because after the 'Dungeon Lord' announced the sealing of the labyrinth's entrances and exits, the same situation indeed occurred.
Fels was also half-believing, half-doubting about this.
What if it was just a coincidence?
The Dungeon shouldn't be controlled by any lord.
After all, it was inherently like an unreasonable, irrational, twisted lifeform.
But speculation was speculation; Fels decided to listen to the conversation.
Then he would make his judgment.
If this 'Dungeon Lord' posed a great threat to Orario, he would need to try and resolve him.
However… once he failed, a conflict between the two sides was bound to erupt.
This made Fels remind himself to be cautious enough.
As he thought of this, Fels couldn't help but shift his gaze towards The Tower of Babel in the distance, and then recalled a word: 'Heretics.'
Fels had been in contact with 'Heretics' for 16 years.
If the 'Dungeon Lord' identity was true, then the fate of those Heretics should be able to change, right?
Just like that, Fels jumped off the rooftop, concealing his figure while moving along the outer wall.
The reason he didn't meet directly was to maintain the advantage of 'the enemy is in the light, I am in the dark.'
However, the situation was completely different from what Fels had imagined—
The moment he crept to the lounge window to eavesdrop, a questioning voice came from inside the room.
"Are you coming in, guest from outside?"
Chen Hai, sitting on the sofa, looked towards the window.
"Huh? Is there someone outside??"
Hestia was full of confusion, her gaze also moving to the empty window.
Just as Loiman and Loki were feeling curious, Chen Hai had already left his seat.
He walked towards the window, saying,
"I don't like sneaky guys."
Chen Hai, who could use his ability to sense the entire Dungeon, could also 'investigate' his surroundings, with himself as the center.
The range is definitely not as good as the Dungeon.
After all, in terms of area alone, the size of the Dungeon can probably cover the surface of this world!
And the person hiding outside had no intention of showing their face.
This is bad!
This was Fels's first thought.
However, as a seasoned sage, he did not panic, but chose to move to higher ground, intending to leave the scene.
As soon as he turned around, Fels saw light.
It wasn't the sun's, nor the moon's, but fire's.
Night's glow shone here!
Boom!!!!
That terrifying fire lit up the night sky above the Adventurers' Guild, and the high temperature, like a roaring beast, engulfed Fels completely!
In an instant, Fels's robe was ignited, turning him into a meteor falling to the ground.
The raging heat was like an unstoppable tide; Fels was utterly unable to resist!
In Orario, Fels possessed the strength of a LV.4 Adventurer.
Although there were still LV.5 and LV.6 above him, reaching LV.4 already placed him among the elite of the elite.
This was because in Orario, half of all Adventurers were at the LV.1 level.
Levels above LV.1 were called Upper-Class Adventurers, with a huge gap from LV.1 Adventurers, requiring sufficient aptitude to cross.
Yet, he, with his level, experience, and skill, had no time to react.
The magical aura expanded instantly, as if without chanting, detecting, locking on, attacking.
Like a tattered rag, the burning Fels crashed to the ground, his whole body in pain, almost unable to move.
But he knew that this was most likely the opponent holding back... "What happened?! Did the Guild explode?!"
"There's too much happening today!"
"First, put out the fire! This guy is burning up!"
"You're Adventurers' Guild staff, right? He seems to have flown out from the second floor."
Outside the Guild headquarters, Adventurers on the roadside noticed the bizarre situation and gathered around.
Looking at the commotion on the street, Chen Hai then returned to his previous spot and smiled at Loiman, saying,
"This is the real show of force. Also, I held back just now. You'd better send someone over quickly to check the situation."
"Ah, this..."
Loiman didn't know what to say, only staring blankly at the wall of the lounge, which had been shattered and destroyed by the fire impact.
It was a large hole, about three meters in length and width, with molten lava still flowing from its edges due to the high-temperature scorching... Bang!
The door was pushed open, and several staff members ran up in a panic.
Loiman waved his hand without waiting for them to speak.
"Send someone to treat Fels, who's at his limit. Don't disturb us later."
The staff members exchanged glances, replied 'We'll do it right away,' and immediately closed the door.
Seeing this, Hestia couldn't help but comment,
"Closing the door seems useless now, doesn't it?"
"Did you take out the Adventurers' Guild's 'phantom' with a single blow?"
Loki clapped her hands.
"As expected of the Dungeon Lord."
"I just don't like people who beat around the bush. I believe Mr. Loiman feels the same way, right?"
Chen Hai, who had brushed off Loki, looked at Loiman.
The person in charge wiped the sweat from his forehead and nodded.
"What the Dungeon Lord says is true."
Loiman, using an honorific, clearly understood that the 'Dungeon Lord' before him possessed extraordinary strength.
