Chapter 4

At Si Fan Palace, where Han Laomo, the old demon, lived alone in his ice palace, no one had ever been allowed to enter. Ning Fan was the first exception.

Pushing the door open, moonlight spilled in, and Ning Fan stretched lazily.

Dressed in white robes and cloud boots, with his long hair tied with jade, he wore a black Daoist robe over it, creating a striking contrast. He looked like a fine young gentleman in this chaotic world.

Though still a youth, his eyes held the wisdom of an old demon.

He closed his eyes, recalling the legacy of the Immortal Emperor. In the Immortal Emperor's memories, there were miscellaneous scriptures, insights, and only one orthodox cultivation technique.

*Yin Yang Change*! The legendary Immortal Emperor, the Great Emperor of Chaos, left this behind!

This technique was divided into ten levels, with Yin and Yang cultivation methods, requiring simultaneous cultivation of both. Each level completed would greatly increase one's cultivation. With the mystic power of the Yin Yang Lock, one could also enhance cultivation when practicing with a woman.

By Ning Fan's estimation, if he cultivated step by step, breaking through the Spirit Fusion stage would take at least several decades. However, if he used *Yin Yang Change* to practice with women, within half a year, he could at least reach the ninth level of Meridian Opening. If he completed the first level of *Yin Yang Change*, his cultivation would increase significantly, and breaking through the Spirit Fusion stage might not be impossible.

Ning Fan opened his eyes, his gaze sharp. With the Yin Yang Lock and *Yin Yang Change*, he would one day become a Void Shattering expert, unstoppable in the Rain World!

The cultivation of *Yin Yang Change* required both practicing with women and consuming flames, using Yang to supplement Yin, to achieve the balance of Yin and Yang.

The first level required practicing with any woman ninety-nine times and consuming nine kinds of ordinary flames.

The second level required practicing with a female cultivator at the Core Formation stage ninety-nine times and consuming nine hundred and ninety-nine kinds of ordinary flames.

The third level required practicing with a female cultivator at the Void Shattering stage ninety-nine times and consuming nine kinds of divine flames.

After reaching the third level of *Yin Yang Change*, one could use the Yin Yang Lock's inner world—the Mystic Yin Realm.

The mysterious woman was trapped in the Mystic Yin Realm. Once Ning Fan reached the third level, he could save her. However, within a few hundred years, Ning Fan did not think he could reach the Void Shattering stage, so practicing with a Void Shattering female cultivator was out of the question for now.

He smiled mysteriously, raised his finger, and a wisp of black flame rose, accompanied by a dragon's roar. This flame, formed from hundreds of ordinary flames, had been transformed into a fire dragon and killed by Ning Fan in the Joyful Union Sect.

This flame belonged to the old demon. Even though Ning Fan's cultivation was still low, with this flame, he could kill anyone below the Spirit Fusion stage like ants. This was his trump card, not to be revealed lightly.

At least, consuming flames was not a concern before the second level. The rest was just practicing with women to complete the first level of the technique.

Ning Fan turned back, and the sound of Zhehe's murmurs still came from the room. He felt a bit hesitant.

"If I practice with Zhehe... I can complete the first level of the technique and greatly increase my strength, but... she's still a child..."

Ning Fan had undergone great changes, and his heart was as ruthless as a demon's, but Zhehe had walked into his heart during his despair and saved him twice.

"In this life, I will not abandon this girl. Some things can wait until she grows up a bit more..."

Ning Fan pondered outside the room, while inside, Zhehe's voice of awakening and faint sobs could be heard.

Zhehe woke up, having saved Ning Fan twice. The first time, she gave him a jade lock and a bun; the second time, she lost her innocence.

But when she woke up and found herself alone, she felt a bit uncomfortable. She didn't understand why, as she had been caught by the Joyful Union Sect at the age of nine and had never interacted with men, nor did she understand emotions. Now, at twelve, she had lost her innocence for Ning Fan, but it had nothing to do with love; she simply couldn't bear to see him die.

But when she opened her eyes and couldn't see Ning Fan, she felt uncomfortable. At this moment, Ning Fan should have been there, but even if he was, what difference would it make? The innocence she had lost could never be regained.

She didn't understand, didn't understand.

Zhehe's small, pale body, covered in scars, pushed aside the silk quilt and got out of bed, but her lower body ached, and she stumbled and fell to the ground.

"Be careful!"

A slender embrace caught her. She was naked, but the other person had no lustful intentions.

"Are you awake?" Ning Fan smiled warmly.

"Ah, big brother, don't look, I'm not wearing clothes!" Zhehe was a bit flustered, realizing that when Ning Fan held her, her already weak body became even weaker.

She didn't understand why, nor did she understand that the pleasure of intimacy was a wonderful experience. Last night, she only felt pain, nothing more.

"Okay, I won't look."

Ning Fan closed his eyes, carried Zhehe back to bed, and began to touch her body.

Ning Fan's gentleness made Zhehe feel a bit better, but being touched by him made her extremely embarrassed, "Big brother, don't... don't... Zhehe feels so strange..."

"I'm treating your injuries, unblocking your meridians, and promoting blood circulation. Sleep for a while, and you'll be able to walk tomorrow."

This massage technique was passed down from the Immortal Emperor's third thought, a technique for the bedchamber. Massaging a woman who had just experienced her first time would help her promote blood circulation, reduce swelling, and alleviate pain.

Ning Fan's technique was extremely subtle. If the old demon saw it, he would be greatly surprised. In just the time it took to burn an incense stick, Zhehe's face was flushed, and her breath was like a fragrant breeze. She felt warm all over, and the tearing pain in her lower body gradually subsided.

She looked at Ning Fan in a daze, feeling a sense of strangeness. After last night's transformation, Ning Fan seemed so unfamiliar, yet he gave her a sense of security.

"Big brother... you're so nice..." Zhehe fell asleep, her smile sweet.

Ning Fan covered her with a thin quilt and examined her face for the first time.

Her child's hair was disheveled, her oval face delicate and tender, making one want to protect her. Her eyelashes were long, and her eyes were closed in sweet sleep.

"If it weren't for you, I would have died twice. I, Ning Fan, am just a lowly life, with nothing to offer in return, but I can give you a promise: as long as I am here, no one in the Rain World can hurt you!"

He gently stroked Zhehe's sleeping face, his touch tender and caring.

As soon as he finished speaking, a carefree laugh came from outside the room, "Haha! You have spirit, worthy of being my disciple! I especially like that last sentence. I, whose meridians were destroyed and can never reach the Golden Core stage, have a disciple who will one day dominate the Rain World!"

Ning Fan frowned. The one laughing outside the door was undoubtedly Han Laomo. He had no particular feelings for Han Laomo, neither good nor bad.

He pushed the door open, his gaze calm. The old demon was startled, as if he were looking not at a youth but at a demon far more powerful than himself.

"Strange, when did this brat's gaze become as sharp as that of the Little Miss? Could he be from the Sword World? Impossible, haha, it must be my imagination."

The old demon looked at Ning Fan more and more approvingly, nodding repeatedly, "I said I would kill you, do you hate me?"

"How could Ning Fan dare to hate my master?" Ning Fan, though possessing the Immortal Emperor's memories, was still of low cultivation and would not provoke the old demon. Moreover, he was speaking the truth; he had little hatred for the old demon.

"Ah, don't hate me. This is a rule set by my master's master's... master—the old ancestor of the Black Demon Sect. The cultivation technique I practice is called *Black Demon Technique*, an ancient technique that only those with the Ancient Demon Bloodline can practice. You also have the Ancient Demon Bloodline, so once you reach the Spirit Fusion stage, I will pass the technique to you."

The old demon laughed, but Ning Fan frowned. Did this old demon really want to take him as a disciple?

"Remember, the Ancient Demon Bloodline is a secret, don't reveal it. When I was young and ignorant, I caused trouble everywhere with my Ancient Demon Bloodline and was stripped of my cultivation... and I also caused... hum, in short, you must not let others know your secret, or I won't be responsible if you die!"

A hint of sorrow appeared on the old demon's cold face, deeply hidden. Ning Fan, with the Immortal Emperor's insight, could see it.

"Remember, protect the women you have been intimate with. Don't be like me... that little girl was poisoned by the Joyful Union Sect's women. The poison is quite strong. Here's the antidote. Feed it to her when she wakes up. I went to the 'Great Void Sect' to get the antidote for your woman and was chased by a group of monks for three days... but let's not talk about that. Oh, and remember, once you finish *Seven Plum Records*, return it to me. If you damage a single page, I'll turn you into mincemeat!"

The old demon threw a small jade bottle to Ning Fan, laughed, and turned to leave, his back slightly lonely.

Ning Fan caught the bottle, opened the stopper, and sniffed the pill's aroma, slightly surprised, "Xu Yuan Pill? A miraculous pill that can cure all Golden Core poisons!"

Ning Fan couldn't imagine that Han Laomo, who had repeatedly said he would kill him, would go to the Great Void Sect to steal such a precious pill for Zhehe.

Escaping for three days... the old demon made it sound easy, but Ning Fan understood the danger. He must have been chased by Golden Core experts for days.

This old demon, ruthless in killing, was genuinely good to him.

"Wait." Ning Fan called out.

"What? I need to treat my injuries!" The old demon was impatient.

"I know a lost method that might cure your meridian poison." Ning Fan's tone was very calm.

"What did you say!"

A flash of shock appeared in the old demon's eyes. He had only told Ning Fan that his cultivation was destroyed, but how did Ning Fan know it was due to meridian poison!

He joined the Ghost Sparrow Sect because its leader was a medical genius, but even after decades of treatment, the leader could only suppress the poison, not cure it.

The poison was like a parasite, even the Xu Yuan Pill, which could cure all Golden Core poisons, couldn't cure it. What could Ning Fan do to cure it?

But the fact that Ning Fan could identify the poison at a glance was astonishing. Perhaps Ning Fan really had a way to cure him?

This was absurd, but what if it was true...

The old demon's mind raced. Looking at Ning Fan, he saw no signs of lying or exaggerating.

"Three days haven't changed you, but you've become as steady as an old man..."

The old demon was still hesitant, but Ning Fan spoke again.

"Absolute Yin, an ancient poison, harmless to ordinary people but effective only on those with the Ancient Demon Bloodline. Once poisoned, the demon bloodline is sealed, and cultivation begins to decline. When cultivation is completely lost, death follows. Initially, the spirit is refreshed, but gradually, the personality becomes violent, and only killing can calm it. In the end, the Yin poison devours the heart, and even gods and spirits cannot save the victim."

Ning Fan's tone was calm, but the old demon heard it like a thunderclap. The leader of the Ghost Sparrow Sect couldn't identify the poison, but Ning Fan, a mere youth, had identified it at a glance.

The old demon didn't know what "Absolute Yin" was, but the symptoms Ning Fan described were all correct!

"Can you really cure me! Who are you? How do you know secrets even the leader doesn't know!" The old demon, excited, grabbed Ning Fan's shoulders, his voice trembling, with a hint of caution.

"I have the Ancient Demon Bloodline and know some ancient secrets. Is that strange? Don't look at my low cultivation; before being caught by the Joyful Union Sect, I was a famous doctor who treated many immortals. If you don't believe me, you can search my soul and erase my memories..." Ning Fan smiled lightly.

Searching the soul and erasing memories was a technique to read someone's memories, but the side effects could damage the mind, even turning the person into an idiot.

Ning Fan was testing whether the old demon was genuinely good to him or just pretending. If the old demon really searched his soul and erased his memories, Ning Fan had a way to make the old demon regret it.

Because he knew a weakness of the "Absolute Yin" poison: under moonlight, Yin energy is strongest, and it's difficult to use magic.

At this moment, the old demon's cultivation was only at the eighth level of Meridian Opening. If the old demon had murderous intentions, Ning Fan could use the black flame to easily kill him.

But when the old demon heard Ning Fan mention searching the soul and erasing memories, he gradually calmed down, his face stern. He believed Ning Fan's words to some extent but was still skeptical. However, he couldn't bring himself to search his disciple's soul.

"I am from the Black Demon Sect. According to our rules, if a disciple violates the demon path, the master can kill them. But if a disciple follows the demon path, the master must not harm them. If you disobey me, I will kill you. But if you haven't done anything wrong, I won't search your soul or erase your memories. Even if someone tries to harm you, I will protect you! Because you are my disciple!"

After the old demon finished speaking, seeing Ning Fan smile without a word, he, with his keen insight, immediately understood Ning Fan's thoughts and laughed.

"Brat, curing me is really important... I need to avenge her... If you really can cure me, what conditions do you have? Speak up!"

"I want to be the young lord of Seven Plum City!" Ning Fan smiled faintly.

"Agreed! From today on, Seven Plum City is yours! 9,752 demon cultivators will be under your command, and you can use any pills, treasures, cauldrons, or immortal jade as you wish!"

The old demon agreed without hesitation, becoming even more satisfied with Ning Fan.

Daring to make demands like a true demon! Unfortunately, Ning Fan still had some reservations about him. Ah, it seems it will take time for him to truly accept me as his master.

"Perhaps I've taken in an extraordinary demon genius! The entrance exam in half a year will surely shock those old fools! Haha, just thinking about their surprised faces makes me happy! But what does this brat want to do as the young lord? Can he control those rascals?"

(*Yin Yang Technique* changed to *Yin Yang Change*... Maybe the book will be renamed *Yin Yang Change* in the future.)
