Dungeon City
There were many reasons why humans failed to immediately suppress the zombies when the apocalypse began.
The sudden change caught everyone off guard, machines malfunctioned without warning, and communication networks collapsed in an instant. Add to that the fractures between people themselves — all these factors combined meant humanity couldn't crush the zombie threat, and instead, the undead only multiplied.
But among all the reasons, one stood above the rest: the dungeons.
When the apocalypse started, thousands of dungeons spawned across the globe. And where they appeared was the real problem.
Some emerged in places of cultural and historical significance, but others took over massive industrial complexes, power plants, airports, ports, railway stations — even parts of mechanized military divisions with heavy firepower. The dungeons destroyed industrial infrastructure and crippled military forces, leaving humanity unable to mount an effective response against the zombies.
Kang Dohyun pointed to a label on the map reading Onsan National Industrial Complex and explained to his brother.
"Looks like this was a major industrial zone."
After Dohyun explained the situation with the multiple dungeons, Kang Dohun asked,
"But, hyung — Ulsan has a lot of industrial complexes, right?"
"That's exactly why Ulsan got nicknamed 'Dungeon City.'"
At that, Dohun finally understood what Ulsan was all about.
The group entered the Onsan National Industrial Complex, an area densely packed with dungeons. They moved along the paths between them, clearing out zombies as they went, until —
"Whoa!"
A colossal blue-barrier dungeon appeared before them. Everyone in the party gasped at its sheer size — everyone except Lee Chaerin, who was still asleep on Dohyun's back.
"We should turn back, right?"
"Obviously. Blue-barrier dungeons are way beyond what we can clear right now."
The group took a wide detour to avoid the blue dungeon and continued moving.
They navigated around the dungeon and emerged from the Onsan National Industrial Complex. A little further on, they reached a bridge — and the view on the other side was staggering.
"Hyung, this is insane."
Just as Dohun said, two enormous circular blue barriers were visible across the bridge.
"Left is the Ulsan Petrochemical Complex. Right is the Yongyeon Industrial Complex."
He checked the map while answering, then sensed something off and activated his aura detection to scan the surroundings.
"And there are tons of zombies between those dungeons too."
The moment they crossed the bridge, the number of zombies surged dramatically.
But now they weren't just Dohyun and Dohun — they had two non-combatants with them, like cargo. Moving quickly was no longer an option.
"A bit early, but let's camp here for the night."
Dohun and Kim Suga nodded in agreement.
The place they chose to stay was an area between the industrial complexes — naturally, there were plenty of factories. And naturally, there were also bandit groups occupying them.
Kang Dohun pushed open the entrance of a large factory and stepped inside.
"What the hell?! Do you know someone here?"
"An enemy?"
The lawless men inside the factory — they watched Dohun warily, but —
"So what are you gonna do about it?"
Dohun charged in and began eliminating the bandits occupying the factory one by one.
Dohyun waited with Kim Suga and Lee Chaerin at a safe distance. Then —
"You can come in now."
After confirming through aura detection that no living beings remained inside except his brother, he stepped into the factory.
Dohun had cleaned it out thoroughly.
"Hyung, no survivors left?"
"Nope. None."
Dohun had eliminated thirty-three enemies in a short span of time, yet there wasn't a trace of fatigue on his face.
"Good work."
"Nah, it was easy. They were way weaker than I expected. Let me loot the bodies."
Dohun smiled as he answered, then began rummaging through the dead bandits' corpses to scavenge supplies.
The factory floor was messy with blood from the battle, so Dohyun took the women up to the rooftop.
"This is clean."
The rooftop was spotless. There was even a shade structure, providing a wide area sheltered from the sun.
"Ms. Suga, please set up the tent here. We'll sleep."
"Understood."
Kim Suga began setting up the tent in the area Dohyun pointed to, and he set down Lee Chaerin, who had been carried on his back.
Zzzzzz
Chaerin was still asleep.
She's definitely changed.
Her sleep time was abnormally long. The brain damage had clearly caused side effects, including extended sleep duration.
At least she's not whining anymore. That's something.
Dohyun asked Kim Suga to handle the tent setup and preparations, then went back down to the factory.
Meanwhile, his brother Dohun was looting the bandit corpses as he wandered through the factory — when he found something unusual.
"Hyung, come look at this."
"What?"
"There's a pile of bodies here."
Following his brother, Dohyun entered a storage room in the corner of the factory.
"....."
Inside were more than thirty corpses — naked female bodies.
"Ah, these guys were truly vile."
That was why there had been no women among the bandits — they had been repeatedly kidnapping women, gang-raping them, and killing them.
All bandits were trash, but these were especially low-quality scum. The brothers both felt they had done the right thing killing them.
After surveying the entire factory, they found plenty of supplies but very little food.
"Dohyun-ah, I'll leave the surrounding area cleanup to you."
He passed information about two nearby bandit groups to his brother, then said,
"There's still plenty of time before nightfall, so I'll go scout around. If I'm late, just have dinner with Ms. Suga first."
"Got it."
After entrusting the area cleanup and the women to his brother, Dohyun mounted his drone and took to the sky.
Dohyun flew around, surveying the area from above.
There are dungeons overflowing to the south.
The Onsan National Industrial Complex, the Ulsan Petrochemical Complex, the Yongyeon Industrial Complex — there were numerous large-scale industrial zones of various types, and dungeons were scattered throughout.
Twenty-one dungeons, just counting the big ones?
He did a rough count and found twenty-one. Dohyun now fully understood why Ulsan was called "Dungeon City."
Dohyun left the industrial zone and entered the Nam-gu urban area.
No dungeons here.
The commercial streets were dominated by zombies. Occasionally, survivor groups could be spotted, but they were few in number. And besides —
They look like bandits.
Most of the survivor groups consisted of men and a small number of women — more accurately, they appeared to be bandit groups made up of men and sex slaves.
From Nam-gu to Jung-gu, most of the survivors seemed to be bandit groups of this type.
Non-combatants and non-bandits probably fled the city.
After surveying, he moved east across the Taehwa River. And here —
More dungeons overflowing.
The Hyundai Motor Company factory and related facilities, plus the large shipyards — all had become dungeons. There were three blue-barrier dungeons just on the east side of the Taehwa River alone.
And with so many smaller dungeons scattered about, Ulsan was definitely a city of dungeons.
He headed north toward Ulsan.
That's the airport.
The Ulsan Airport had become a yellow-barrier dungeon. And in Buk-gu, there were noticeably more survivor groups than in Nam-gu, Jung-gu, or Dong-gu.
They're closed off. Definitely closed off.
Probably because bandit groups were so prevalent in other areas, the survivor groups showed an exclusive, insular disposition toward outsiders.
And —
There are a lot of small dungeons in Buk-gu too.
While there were no large industrial complexes like in Nam-gu and Dong-gu, there were many smaller industrial zones, so numerous small dungeons were observed.
But most importantly —
Four yellow-barrier dungeons.
He found nine dungeons in Buk-gu alone, four of which were yellow-barrier.
Dohyun completed his reconnaissance of all of Ulsan and returned to the base camp. When he landed on the rooftop —
"You're back."
Kim Suga greeted him.
"Eup! Eup!"
Lee Chaerin, who was bound and gagged, also gave Dohyun a delighted look upon seeing him.
"Everything went well? Where's Dohun?"
"Yes, your brother is downstairs."
"I'll go down for a moment."
He went straight down to the factory building, where Dohun was lying down, having already set up a tent in a clean spot.
"Hyung, you're back?"
His brother had already showered and was resting.
"Did you clean up the area well?"
"Yeah, cleaned it up nice and tidy."
Dohun had eliminated the two additional bandit groups nearby, and his expression was bright.
"Those bastards were crazy too. Killed them all good."
"Good. Thanks for the hard work."
"I already ate dinner. You eat too. And I'm sleeping here tonight."
Dohun said he'd sleep inside the factory rather than on the rooftop, so Dohyun thanked him briefly and went back up.
Kim Suga had prepared a feast.
"Wow, what is this?"
"Mr. Dohun brought back wild boar meat, so I tried making a few meat dishes."
Dohun had found frozen wild boar meat while looting the bandits. Thanks to that, dinner was very abundant.
Dohun began eating his dinner with relish. And Kim Suga, noticing that Chaerin was suffering, loosened her gag slightly to give her water.
"Master! Master! Please fuck me! Please ram it into my ass! Please!!"
After being left alone for three hours, Chaerin's headache had been growing worse. The moment her mouth was freed, she began begging.
"She's being loud. Put the gag back in."
"Yes."
Chaerin's gag was reinserted, and she was left alone until Dohyun finished his meal.
After Dohyun finished eating and showered, he went to Chaerin and removed the gag from her mouth.
"Master!!! Please!!!"
Chaerin begged through tears. Dohyun, wearing only his underwear, immediately stripped and pulled out the dildo that had been inserted in her, then thrust himself inside her.
Thwump!
"Haaahhh!!!"
Even with just the insertion, Chaerin reached her climax and let out a loud moan. And then —
Squelch.
Urine leaked from her urethra, and her eyes went unfocused.
"She came right away?"
When Dohyun pulled out, Chaerin immediately closed her eyes right there and —
Zzzzzzz
She fell asleep.
This was Chaerin's reality — mentally, physically, and through the slave contract, completely subjugated to Dohyun. It was convenient for him, but —
It feels empty.
His cock was still erect. So —
"Shall I take care of you?"
Kim Suga, who had been nearby, quietly approached and asked.
"Yes, please."
Kim Suga smiled seductively and began undressing. Then the two of them went into the tent, and —
"Haa.. hah! Ah! It's good!"
Kim Suga's moans flowed out of the tent for a long while.
