Solomon's 72nd dungeon is like an 'arena' for demons.

Some might be dissatisfied that the means to prove one's strength became dungeon management ability rather than individual versus individual strength, but ultimately, to prove strength as a being in the Demon King's army, what mattered was how much you contributed in the war against the human alliance.

And those at the very bottom could be said to be the most passionate about that. In reality, how many become dungeon masters to contribute to the Demon King's army, but anyway, being the most active and passionate, their rank changes were also frequent.

"From 66th to 72nd rank. The dungeons whose masters change most frequently. The Andromalius dungeon you just conquered is like that too, Master."

Shaitan spoke first. After Shaitan's emergency report, we gathered at the Ras Vegas government office meeting hall.

Me, Lune, Shaitan, Gremory, Eila, Meri. Though the gender ratio leaned one way, this composition was essentially our dungeon's executives.

"So maybe Dantalian's dungeon at 71st also disappeared?"

"Correct. If the dungeon master temporarily died or vanished, the portal might not open. Of course, like higher-ranked dungeon masters, they could use illusion magic to conceal their dungeon, but..."

"Solomon's system comes first. No matter how skilled in illusion magic, you can't fool the system."

Gremory refuted Shaitan's answer to my question. Even excluding praise for Solomon, there was no way anyone tricked Solomon's system. Much less a 71st-rank dungeon master.

"So right now, Dantalian's dungeon definitely 'doesn't exist'?"

The portal won't open. That was no different from saying dungeon connection through the system was impossible. In other words, the dungeon of a demon named 'Dantalian' currently doesn't exist.

"Maybe someone already conquered it and registered it as a sub-dungeon?"

"But I'm currently registered as Andras's dungeon. And Gremory came to attack my dungeon registered as Andras's dungeon. Shaitan, same with Andromalius's dungeon, right?"

"Correct. Unless a new Andromalius officially appears, if someone opens a portal to attack the 72nd dungeon, it will be here. The portal door will become the entrance to the sub-dungeon or open somewhere in this dungeon."

"Right. The farthest place from the entrance. ...Wait, isn't that connected to Gremory's dungeon by portal?"

"I think the system probably adjusts it automatically, but I heard that when the sub-dungeon entrance is too close to the summoning facility, the portal spawns at the farthest place."

"Who told you?"

"I heard from Lord Solomon."

Can't argue with a statement from the source. Gremory, who wanted to argue about something, and Meri, who was mulling over the system's loopholes, no longer argued. What mattered now was that a portal to Dantalian's dungeon wouldn't open.

"Any other opinions?"

"What about cases where another dungeon is conquering Dantalian's dungeon? For instance, fundamentally blocking third-party intervention in 1:1 between dungeon masters."

Eila seemed to think it might be a sacred duel ritual. But in such cases, wouldn't the system display different text? Shaitan also seemed to read my thoughts, seeking my permission before answering Eila.

During a Seizure Battle, only one portal opens. That was the summary of Shaitan's words.

And while Shaitan talked about dungeons, I mulled over the system notification.

"Doesn't exist, doesn't exist..."

Dantalian, the 71st dungeon doesn't exist. Then what's the reason the portal won't open? Thinking about how the Seizure Battle system works, the conclusion converges to one thing.

"Got it."

I came up with one hypothesis. And to confirm that hypothesis, I immediately stood up.

"Lune. Tell Lime to gather all Slime Dragons. I'm going out myself."

"Yes. Where will you install the portal?"

"Right in the center of the cavity. Not going far, gonna raid it right away."

Lune ran to the portal without any doubt. While Lune trusted my orders unconditionally without question, the other four looked at me with puzzled faces.

"Did you figure out another method?"

"Yeah. If I'm right, it's an immediate raid, if not, just watching... but doesn't really matter. Either way, the main goal is stomping all those below me."

If I eliminate all dungeons from 64th to 72nd rank, I won't have to worry about uprisings. I'd already eliminated the 72nd dungeon, but didn't seem necessary to knock down all those dungeons one by one.

"The war's already started, and I'm not the only one thinking of beating down everyone. If there's a scumbag like me stomping lower-ups, there's bound to be underdogs trying to tear off higher-ups' heads. The latter would be overwhelmingly more numerous."

"...Ah, that's possible."

"I apologize, but I don't understand what you mean."

Shaitan didn't understand at all. Same with Eila. Born high and noble, the two didn't know an underdog's feelings. Having never been robbed, not feeling the need to rob from someone, they couldn't think of it.

"It's simple."

I raised my palm lying horizontal at the bottom one step up.

"If there's someone going down from above, there's naturally someone climbing up from below. Shaitan. The 71st dungeon won't open? Then check the 70th, 69th dungeons. Don't actually open them, just check 'if they can be opened.'"

"...Please wait a moment."

Shaitan also briefly crossed through the portal.

"Eila. I'm entrusting you with the orcs. If enemies attack, you can personally lead the army and smash them."

"...Master, are you really okay with that?"

"Your level's risen considerably, and more importantly, our troop composition is better than humans in quality and quantity. Orcs, Andras, harpies. Use these three species well. From now on, defending Ras Vegas will be your exclusive responsibility."

"Understood. ...I'll do my utmost to defend it."

Eila even knelt on one knee from her seat and bowed to me. Her expression was so solemn I almost became serious too.

"Eila Aries, following Master's command, I'll stake my life to defend this city."

"Are you crazy? Making you defend with your life?"

I immediately lifted Eila's body and smacked her butt. Eila flinched at suddenly having her butt slapped, and I raised my palm to slap Eila's chest left and right instead of her cheeks. Not painfully, just enough to heat up slightly.

"Ahng...!"

Eila's lips trembled at my not-quite-punishment punishment. She couldn't understand why and how she was being punished this way. But as lord of Ras Vegas, there was one mindset she should have.

"What did I tell you to do if this city seems about to fall?"

"...You mean to escape through the portal?"

"Obviously. Run if you're gonna die. Don't act tough saying stuff like 'Kugh, kill me' like before. The only time you say stuff like that to me is when we're doing that kind of play on the bed. Got it?"

"...Understood. I apologize."

Eila bowed her head deeply. I comforted Eila by fondling her perky chest.

"Yes, yes. I'll think of it as coming from excessive loyalty to me."

"Master."

Shaitan quickly checked and returned.

"A portal won't open to the 70th rank, Seere's dungeon either. Likewise, a portal won't open to 69th rank Decarabia's dungeon. But..."

"68th rank is possible?"

"...Yes. It's possible to open a portal to the 68th rank, Belial's dungeon. Just in case, I checked and it's possible to open portals to all from 64th to 67th rank."

The 72nd dungeon I'd surprise attacked had vanished. And dungeons from 71st to 69th rank also vanished.

"Hehe, I see. As expected, a demon living up to their name."

"What?"

"Just rambling. More rambling... wish they'd kept that name, but they changed it themselves, so can't help it. Eila! I'm counting on you for the rest."

I pointed beyond the portal to Gremory and Shaitan. Eila rushed to my side with bewildered eyes.

"M-Master...?"

Eila rubbed her thighs and rolled her eyes left and right. From my touching, Eila seemed slightly heated up. I slowly pushed my hand that had been touching Eila's chest and butt into Eila's underwear.

Squish.

Soaking wet. I pulled my finger out and pointed Eila to the government building.

"Spend tonight alone. Punishment for saying you'd die on your own."

"...."

What punishment is more effective for those addicted to Ras than sleeping alone? Eila stood there blankly with a world-collapsed face, and I crossed the portal with Shaitan and Gremory.

"You're mean."

"Says the one who'll pounce on Eila right when midnight passes."

"Obviously."

Tonight's sleeping alone. Once midnight passes it becomes tomorrow night, so if I enter the bedroom right at 12:00, she'll come in saying she likes it while embarrassed. The timing was just perfect too.

"Master, we're ready."

Lune was waiting in the middle of the dungeon's cavity leading the Slime Dragons. Already the evolved Slime Dragon Units 1 through 3, and following them, newly summoned Slime Dragon Units 4 and 5. A total of five Slime Dragons were waiting for my orders.

"Then let's prepare to attack. You rested well, right? Gotta go raid the next dungeon right away."

"Ready to open the portal."

Shaitan unbuttoned the shirt covering her lower belly. A heart-shaped red light sparkled as a tattoo, ready to open a portal to anywhere I wished at any time to launch a surprise attack.

"Preparations are done, so let me explain. Frankly speaking, Dantalian, the master of the 71st dungeon, smashed 70th and 69th and stole their names. Starting with Dantalian, he became Seere, then Decarabia."

In other words, Dantalian crushed the heads of the two above and took their positions. That was my hypothesis and conclusion. Just like how I, who was outside the list, snapped Andras's neck and stole Andras's dungeon.

"Lune was beside me then. Lune, remember? Do you remember the conditions when robbing another's dungeon? Three. Multi, sub, and lastly."

"You said you'd register as 'Andras'?"

"Right. That's also the path to climb to higher ranks. Of course, new Andromalius, Dantalian will appear in the empty spots, but..."

How much could a new monster entering the arena as a newbie after being crushed once really perform? Veterans had already matched their grades to 5-star, 6-star and evolved their subordinates into all kinds of high-grade, high-level individuals.

"No need to worry. Even if we just block one speed bump below, we can block enough. In that sense, the dungeon we'll attack is this place."

I drew numbers on the floor. The executives immediately grasped the meaning after hearing my words and seeing the number.

"Indeed. It'll definitely serve as a speed bump."

"Right. Blocking the entrance after eating multi is the most basic of basics."

On the floor was written the number 64.

The rank directly below Andras, a dungeon with the name [Flauros].

"Our dungeon's speed bump is here. And after completely eliminating the danger below..."

"We just need to eliminate from 57th to 62nd rank. Don't worry. 57th Ose and 58th Amy—I robbed them both so many times they went back whining like idiots."

"That's good news. Then let's go. Shaitan, open the portal."

"Yes."

A portal opened right in front of the cavity. The reason for not installing it far away is that I and my legion are confident of victory against Flauros.

"Let's go."

Lune, Lime, and five Slime Dragons. The winning combo that conquered Gremory's dungeon in the past, plus Slime Dragons.

Plus me.

An unbeatable combination.
