Bangudae Petroglyphs
Today was the first day he had lost a sparring match to his younger brother. Kang Dohyun was in a foul mood. And so, on this particular day—
Thud! Thud! Thwack!
"Hahk… ah-hahk… aheung… haaang!! Haaaaaang!"
He slammed his hips so roughly that Lee Chaerin collapsed in the throes of orgasm.
"Heh… heh… heuut…"
Pissing herself as her entire body went limp, Lee Chaerin lay sprawled and spent. Kang Dohyun pulled his cock free of her cunt and went over to Kim Sua, who had been resting nearby.
"M-me? Me again?"
Kim Sua flinched in alarm, but Kang Dohyun seized her hand and made her stand gripping the wall.
"S-stop—!"
She refused, but his cock—
Squelch.
"Haugh!"
—drove into her cunt regardless of her wishes. And then—
Squelch, thud! Thwack!
"Haut! Ah… it hurts! Aeut! Aaang!! It hurts! Aeut!"
Kim Sua cried out that it hurt, but Kang Dohyun only kept slamming his hips harder, and his hand as well—
Slap! Slap!
—cracked down hard across her ass until Kim Sua's already thoroughly spanked buttocks flushed a deep, burning red.
Her ass ached, but what throbbed worse was her cunt. She had simply been fucked too many times. And so—
"Dohyun-ssi, please… haut! Please stop now! Haugh! It hurts! I'm exhausted! Aeut!"
At last Kim Sua begged, worn past her limit—but today Kang Dohyun had no mercy. He kept driving his hips in hard.
"Ah! Ahang… aeut! Haaang!!"
Bit by bit, Kim Sua's moans turned sweeter. The pain was still there, but the pleasure swelled until it overtook it completely.
And so the sex between the two of them grew scorching hot.
From early evening on, Kim Sua and Lee Chaerin had to absorb his lust. Kang Dohyun worked out his rage in a threesome with both women.
Inside the tent, the moans of pleasure and pain that Kim Sua and Lee Chaerin took turns crying out did not stop until dawn.
The next day.
Because Kang Dohyun's sex with the women had stretched until dawn, neither of them could get up in the morning.
Kang Dohyun and Kang Dohun ended up eating breakfast alone—the younger brother smiling, the older still wearing a resentful scowl.
"Hyung, let it go already."
"…"
"You know as well as I do that if we fought for real, I'd lose. So drop it."
At his brother's words, Kang Dohyun let out a single sigh.
"From now on, you spar whenever I want."
"Fine. I will."
And just like that, the lingering grudge from yesterday's match was settled.
"Hyung, what are we doing today?"
"Dungeon runs, obviously."
They had leveled up and bulked out their specs considerably, but it still wasn't enough.
The brothers wanted to grow stronger still, and Ulsan remained a place full of easy opportunities to do exactly that.
"There's one light-green dungeon left. After that one, we go after the yellow dungeons."
"Every yellow dungeon in Ulsan? Then what about the white ones?"
"For now, let's clear everything up through yellow."
They finished breakfast while talking it over, and the two of them immediately—
Woom.
—summoned the drone and climbed aboard. Then they flew straight for the light-green dungeon.
It was exactly the fifteenth day since the party had arrived in Ulsan.
BOOM! BOOM! BOOM!
A chain of explosions ripped through Ulsan Airport.
Kang Dohyun and Kang Dohun had been roaming around setting fire to the zombies inside the dungeon, and the flames clinging to the burning undead had caught the aircraft parked on the tarmac and detonated them.
"Burn nice! Burn it all down!"
From atop the drone, Kang Dohyun and Kang Dohun sprayed fuel and herded every last zombie into the fire.
They waited a while, watching the zombies burn across the runway, and then—
You have cleared the Ulsan Airport Dungeon.
Additional experience acquired.
Additional Zombie Coins x400 acquired.
They had successfully cleared the Ulsan Airport Dungeon as well. And then—
A message even came through announcing they had broken the clear-count world record.
Having cleared the Ulsan Airport Dungeon, the brothers walked back to base camp.
"You're back early."
It was still broad daylight. Kim Sua was inside the tent helping Lee Chaerin masturbate after the other woman had started complaining of the ache.
"Hauh… hauh… Master…"
Sweat-slick and dripping arousal from her cunt, Lee Chaerin smiled when she saw Kang Dohyun—but he ignored her completely and spoke to Kim Sua.
"You've been working hard. Nothing unusual?"
"No. But… I haven't started dinner yet."
The brothers had returned relatively early, so she hadn't had time to prepare the evening meal.
"That's fine. There's still plenty of time before dinner. Take it slow."
"Then…?"
Kim Sua glanced toward Lee Chaerin as she asked.
"Yeah. Keep working that bitch over."
"Yes."
Kim Sua went back into the tent and started working the vibrator already buried in Lee Chaerin's cunt.
Squelch, squelch, thrust.
"Haaang! Ang! Aaang!"
And Lee Chaerin screamed with pleasure.
Finished talking with Kim Sua, Kang Dohyun headed straight for the shower tent set up in the corner of the greenhouse, while Kang Dohun—
"Training time, training time!"
—threw himself into exercise even for that short stretch of free time.
Kang Dohyun stepped into the shower tent, stripped, and turned on the water.
Shhhh.
Standing under the cold spray, he sank into thought.
Fifteen days since arriving in Ulsan. The two brothers had been ranging across Ulsan and the southern reaches of Gyeongju, clearing dungeons as they went.
Clearing fourteen more had brought their total to eighteen dungeons cleared.
The moment we cleared twelve, the world-first record started ticking.
A message had said that world-record clears paid out cumulative rewards.
Right now the brothers had set the world-first mark from twelve all the way through eighteen—seven record updates. When the time came to settle up, the payout was going to be enormous.
After finishing his shower, he sparred lightly with his brother. And when evening arrived, Kim Sua had dinner ready.
A simple meal of rice, soup, and side dishes. The party ate and talked.
"Hyung, so there are no light-green or yellow dungeons left in Ulsan now?"
"Yeah. None."
White dungeons and blue dungeons still littered the map in huge numbers, but every easy dungeon in Ulsan had been cleared by the brothers.
"Nothing on the Ulsan–Gyeongju border either?"
"Nothing there either."
Kang Dohun wanted to push their world-first dungeon clear count to twenty.
"Hyung, shouldn't we clear two more somehow?"
But white barrier dungeons were a coin flip.
Even among white dungeons of the same color, difficulty varied wildly, clear times differed enormously, and the rewards were completely unpredictable.
"Yeah. If we're going to clear white barrier dungeons anyway—"
Kang Dohyun brought up a place he had already been considering.
"Let's try the Bangudae Petroglyphs."
The place Kang Dohyun named was the area around the Bangudae Petroglyphs, one of Ulsan's famous historic sites.
The Bangudae Petroglyphs—carvings cut into the cliff face along the Taehwa River at the western edge of Ulsan, depicting the daily lives of people from the late Neolithic through the Bronze Age.
Kang Dohyun had chosen this spot because, before his regression, he had once heard that someone had gotten something excellent out of the Bangudae Petroglyphs dungeon.
But at the time it had only been a rumor, and the dungeon in question had already been cleared, so he had never looked into the details.
I should have paid closer attention back then.
He regretted it now, but there was no use dwelling on it.
Still—there was a rumor that someone got something good.
He didn't know the particulars, but the information that something valuable had been obtained was enough. He decided they would go to the Bangudae Petroglyphs.
The next day.
Early in the morning, the brothers boarded the drone and headed west across Ulsan.
"Bangudae's pretty far out, huh?"
"Yeah. It's administratively Ulsan, but it's way out on the fringe."
After about twenty minutes of flying along a tributary of the Taehwa River, they arrived at the Bangudae Petroglyphs area.
And there, just as expected, stood a single white-barrier dungeon.
A white dungeon that had swallowed part of the Taehwa River itself.
"A dungeon that includes a river? Something water-related might come out of this."
"Bangudae Petroglyphs—that's the famous rock art, right? You know anything about it?"
"Nope."
They thought it over, but neither of them had any special information.
"Is there any point preparing?"
"Probably not. Let's just go in."
The two brothers finished their combat preparations and entered the dungeon at the same time.
The moment they stepped inside, the world changed.
"…"
The sky had turned blue, and both of them felt as though they were underwater—though, fortunately, they could still breathe.
"What the hell?"
"No idea."
As they looked around—
The message carried the words Special Dungeon. And a moment later, the current began to quicken—
Mmmmmuuuhhh… oooooong… uuuuuummm…
A deep, low-frequency resonance. A thoroughly unique cry rolled through the water.
"Stay sharp."
At Kang Dohyun's warning, Kang Dohun went on guard. Moments later, a being radiating a strange light arrived on the current.
The master of the Bangudae Petroglyphs dungeon—the Whale Spirit Garnok—had appeared.
