The Heaven and Earth Yin-Yang Intercourse Divine Art
"What? Saekgong? Are you serious?"
Seong-il's face was frozen in pure disbelief. Saekma looked back at him with an expression of solemn dignity.
"It seems the Young Master is dismissing Saekgong. Allow me to clarify—Saekgong is, in fact, an extraordinarily powerful martial art."
The Young Sect Leader glared at Saekma with the same expression one might give a pile of garbage. Saekma, however, ignored her completely and continued his explanation.
"Since the Young Master spent three months inside the Taoist sect, this should be easier to explain. There's no need to overthink it. Why? Because Saekgong is a martial art built directly on Taoist foundations!"
"What is the root of Taoist philosophy? Nothing less than a cosmology based on the harmony of yin and yang! My Saekgong was created on exactly those Taoist yin-yang principles!"
Now genuinely intrigued, Seong-il asked, "What kind of martial art are we talking about?"
"It's simple! The Heaven and Earth Yin-Yang Intercourse Divine Art I cultivated is a technique born from contemplating the natures of heaven and earth, yin and yang, then adapting them to the human body!"
Saekma paused to catch his breath before continuing.
"Just as yang and yin exist in the world, humans exist as male and female! Ordinary Taoist martial arts analyze the human body—a being born from heaven and earth—then build internal energy by harmoniously absorbing yin and yang through breathing and training. It's true that storing the yin and yang of heaven and earth inside one's body is both safe and a cultivation method close to the Great Dao."
"However! Although humans are born from heaven and earth, they are existences separated from it! Strictly speaking, they are distinct from heaven and earth, which lowers efficiency! But the Heaven and Earth Yin-Yang Intercourse Divine Art is different!"
"Why?! Because men are yang and women are yin. This mental technique was built on the concept of humans as yin and yang, making cultivation far easier and faster than drawing from heaven and earth. After all, the fact that men are yang and women are yin is an observable truth!"
"And that's not all! When a man and woman engage in intercourse and mutually supplement each other's vital essence, they can train simultaneously as a pair. The efficiency skyrockets!"
"Since the yin and yang closest to humanity—men and women themselves—are cultivating at the same time, the amplification effect can reach dozens of times higher! In theory, no internal energy mental technique accumulates power faster than the Heaven and Earth Yin-Yang Intercourse Divine Art!"
"Furthermore! Because it was created from Taoist theory, it boasts excellent compatibility with Taoist martial arts. I can confidently say it will pair especially well with the Young Master's sect's Taeguk Geomgyeol! If I'm wrong, I'll press my own hand onto a hot stove!"
"If you train my Heaven and Earth Yin-Yang Intercourse Divine Art diligently and consistently, you will be recognized as a proper martial artist within a year, and called a peak expert within three to five years!"
Seong-il melted under the weight of those words. Before he realized what he was doing, he dropped to his knees and begged.
"Saekma, sir! Please teach this unworthy one your martial art!"
The Young Sect Leader stared at the pair with the expression of someone watching two certified idiots.
"Excuse me... Young Master."
"Quiet! This is the important part!"
"...."
The Young Sect Leader watched Seong-il's ridiculous display until she finally couldn't stand it anymore.
"That... according to the Lust Demon's theory, that mental technique would accumulate internal energy at the absolute fastest rate in the world. Correct?"
When Seong-il nodded eagerly, the Young Sect Leader let out a long sigh.
"Then let me ask you this. If such a technique that builds internal energy so quickly exists, why has no supreme expert ever emerged from it?"
"Huh...?"
She looked at Seong-il with pity in her eyes and continued.
"Does it not occur to you that there must be a reason such a speed-focused technique isn't considered the greatest martial art...?"
"Speed-type techniques always carry side effects. Or they come with severe restrictions. Just look at that Lust Demon. Even after training that Heaven and Earth Yin-Yang Intercourse Divine Art—or whatever he calls it—for decades, he still got absolutely demolished by me, someone who's only practiced martial arts for about fifteen years."
At her words, Seong-il's kneeling posture straightened instantly. He was so furious he was about to unleash a torrent of curses at Saekma when...
"Of course, that would normally be true! But the Young Master is different."
At Saekma's decisive tone, Seong-il dropped back to his knees.
"Why?"
Saekma grinned slyly and continued.
"Because the Young Sect Leader is right here!"
"?"
When Seong-il stared at him with an expression that screamed what the hell are you on about, Saekma cleared his throat loudly and began to explain.
"In ordinary circumstances, the Heaven and Earth Yin-Yang Intercourse Divine Art can only safely be cultivated up to the sixth level."
"Why? Because this mental technique gradually transforms the male body into a 'Pure Yang Physique.' A Pure Yang Physique is a body composed of pure yang energy that grants immense physical power... The problem is that the stronger the yang energy becomes, the greater the yin energy required to balance it."
When Seong-il continued staring blankly, Saekma smiled and pressed on.
"Consider this! After absorbing yin energy through intercourse, the man grows stronger. If his yang energy increases significantly, will he need more yin energy or less?"
"...More?"
"Exactly! The deeper one cultivates the Heaven and Earth Yin-Yang Intercourse Divine Art, the more yin energy it demands! The usual solution is simple—absorb yin energy through an enormous amount of sexual activity!"
Seong-il tilted his head. "Then couldn't you just get married and do it with your wife all day?"
Saekma shook his head.
"If only it were that easy. The problem is that a woman's yin energy is not infinite. If she receives too much yang energy from a man through repeated acts, her own yin will weaken. That's why you need other women to fill those gaps."
"Which is exactly why I met woman after woman and shared the pleasures of the clouds and rain with all of them!"
The Young Sect Leader spoke with open revulsion. "So you piled up grudges from countless people, got labeled a public enemy of the murim world like the idiot you are, and ended up in this sorry state."
Her words struck the mark perfectly. Saekma lost his train of thought for a moment, smacking his lips before continuing.
"Yes... One of the main reasons people fail while cultivating this art is indeed the accumulation of enemies and grudges."
"Why? Once you're strong enough, can't you just beat everyone up?"
Saekma gave Seong-il a look that said are you stupid.
"Young Master. It looks like you've read quite a few wuxia novels during your three months rolling around in the West... In a fight, ganging up is king. No matter how strong you are, if the numbers are against you, you lose. Got it?"
Wait... did he just use some weird modern slang?
"Anyway, to continue—the Heaven and Earth Yin-Yang Intercourse Divine Art is powerful, but it has many external variables. The grudge problem the Young Sect Leader mentioned is the prime example."
"But the Young Master doesn't need to worry about any of that."
"?"
When Seong-il gave him another why look, Saekma smiled brightly.
"As I said before, it's all because of the Young Sect Leader."
"???"
When Seong-il still looked lost, Saekma sighed.
"Your application skills are rather poor. You must be weak with variant questions, so passing the old civil service exams would have been difficult for you?"
"What the hell are you babbling about, you bastard?"
Unable to endure any longer, Seong-il cursed. Saekma quickly cut to the point.
"It's because the Young Sect Leader possesses the Heavenly Yin Physique."
"Ah!"
"Now you're getting it? Correct. It wouldn't be an exaggeration to say the Heaven and Earth Yin-Yang Intercourse Divine Art was practically created to meet the Heavenly Yin Physique."
"As explained earlier, after the sixth level, the Heaven and Earth Yin-Yang Intercourse Divine Art requires enormous amounts of yin energy, which means many women. That process creates countless real-world problems and obstacles."
"But if your partner possesses the Heavenly Yin Physique, everything changes. Why? Because a woman with the Heavenly Yin Physique is the owner of infinite yin energy. Normally, practitioners hit a wall at the sixth level because they need so much yin."
"With a Heavenly Yin Physique that provides unlimited yin, however, the story is completely different. You simply continue sharing the pleasures of the clouds and rain with her, and your cultivation advances naturally. That is precisely why I said the Young Master is in the optimal position to cultivate the Heaven and Earth Yin-Yang Intercourse Divine Art."
"I see...! So that's why!"
Seong-il finally understood why Saekma had spoken so confidently about learning his Saekgong.
At that moment the Young Sect Leader spat out in disbelief, "You two idiots. Do I not get any say in this?"
Saekma shamelessly shot back, "But Young Sect Leader, weren't you captured by that black bead and had even your soul bound? Seeing how obedient you've been, that bead's power must be real. Since you're stuck like this anyway, why not become that sort of relationship with the Young Master? Once you two get physically intimate, I'm sure he won't treat you badly!"
"This motherfucker is really asking to die..."
Swearing viciously, the Young Sect Leader began mercilessly torturing Saekma with the Poison Gu.
"Kek!! Kuek!!"
Seong-il hurriedly stopped her. "Stop that right now!"
"Why should I! Hmph! What are you going to do if I don't?"
When the furious Young Sect Leader snapped back, Seong-il simply dropped one word.
"Pain."
"Kyaa! Kuaaak! Kuaaaaaaaaaaak!!!"
As the two of them thrashed wildly on the floor in agony, Seong-il looked at the Young Sect Leader.
"What did you just say?"
"I'm sorry! I must have lost my mind in anger!! Young Master, I was wrong!!! Kyaaaaak!!"
"Then stop the Poison Gu immediately."
"I'll stop it the moment you stop the pain! Please!! Uuugh!"
Seong-il ended her pain. Only then did she stop the Poison Gu's convulsions.
What is this, some kind of reservoir dog hierarchy? Me > Young Sect Leader > Saekma > me...?
Seong-il suddenly remembered a scene from a classic movie he'd seen at the repertory theater. Three men pointing guns at each other's heads.
Ah. I've been talking with these maniacs so long that I'm starting to lose it too.
"Eun-wol."
Seong-il quietly called her name.
"Y-yes! Young Master."
"I'm sorry, but I think I need to seriously consider Saekma's method."
The Young Sect Leader immediately protested with a look of pure disgust.
"Young Master! Think this through! Is there any guarantee that this Lust Demon bastard will properly and completely transmit a real martial art to you? He hasn't said a single word about the actual side effects! And you're still going to accept it?"
Huh...? Now that she mentions it.
Seong-il recalled how Saekma had glossed over the side effects when talking about making many enemies.
"Now that you mention it... what are the side effects of the Heaven and Earth Yin-Yang Intercourse Divine Art?"
Saekma's face twitched. He began, "Well... that is to say..."
"Short. Fast."
Having figured out Saekma's long-winded personality, Seong-il had no desire to let the man drag things out.
"Levels one to three require intercourse at least three times per week. Levels four to five need it at least twice per month. Levels six to nine require it at least once every six months. Levels ten to eleven need it at least once per year. Fail to do so and your brain explodes. Aside from that, it just increases sexual desire slightly?"
"And level twelve...?"
"At level twelve, it's perfected, so you won't die even without it."
"Understood."
Having completely grasped the nature of the martial art, Seong-il sank into deep thought.
Even if I can't find a sex partner here, couldn't I just do it with my partners in Pocket Girls? Or would that not work? Since the me inside the game and the me outside aren't linked, maybe it's pointless?
After long deliberation, Seong-il finally made his decision.
If I keep living like this, I'll just get pushed around by combat-capable people for the rest of my life. If something happens in the field with an ability that can't even fight properly, I'll die like a dog without being able to resist.
And that bastard Go Yeong-tae.
The face of Go Yeong-tae, who had constantly humiliated him, floated up in his mind. The deep grudge buried in his chest rose to the surface. Overwhelmed by the desire to crush that son of a bitch, Seong-il finally resolved to learn Saekgong.
After all, if you don't risk losing anything, you can't gain anything either.
"Saekma, sir. Please teach me the Heaven and Earth Yin-Yang Intercourse Divine Art!"
Seong-il knelt before him, bowing his head and formally requesting instruction.
Saekma quickly helped him up.
"Aigoo! Young Master, you don't need to do this! I'm only transmitting the art out of my own necessity as well!"
"What necessity?"
Then Saekma answered.
