Alert! The Dragon Lord has emerged from seclusion!

"My daughter Qingxue, if you see this book, you will have already awakened the Profound Yin Body. This body is a gift from Heaven, but also a shackle of destiny. To break free of this shackle, you must seek the Nine Yang Body, achieving harmony between Yin and Yang, to attain the Great Dao. However, the Nine Yang Body is rare, something you can only encounter, not seek. If you never encounter it in your lifetime, remember never to force yourself to cultivate the most Yin techniques, otherwise the cold energy will backfire, and you will not live past thirty. Mother."

The signature is "Murong Wan", and the date is eighteen years ago.

Lin Chen closed the book, a sudden realization dawning on him. No wonder Su Zhenbang valued the marriage so much; it turned out that Su Qingxue's mother had already foreseen that her daughter needed the Nine Yang Physique to help her.

He took the books and the warm jade with him.

When they returned to the ground, it was already broad daylight.

After a night of turmoil, the Su family manor was now unusually quiet.

Most of the tribespeople have moved as planned, leaving behind only loyal guards and a few elderly stewards.

Su Qingxue was in her study reviewing intelligence reports from various regions when Lin Chen returned. Her gaze fell on the "Mysterious Yin Chronicle" in his hand, and she paused slightly, "This book..."

"Found in the warm jade display case, it should have been left by your mother." Lin Chen handed the book to her.

Su Qingxue took the book, her fingertips lightly tracing the cover, a complex emotion flashing in her eyes: "My mother passed away when I was three years old, supposedly from a relapse of an old illness."

"Now it seems that it may also be related to the Xuan Yin Body."

She turned the pages of the book, and her fingers trembled slightly as she read the last page.

Lin Chen waited quietly until she calmed down before speaking: "The warm jade has been obtained. Tonight at midnight, when the yin energy is at its peak, we can begin to clear away the yin energy. Before that, I need to prepare some auxiliary materials."

"Just say what you need." Su Qingxue closed the book, her expression now calm.

"Three qian of cinnabar, a piece of century-old peach wood heartwood, and three drops of pure yang chicken blood—it must be from a rooster over five years old, and the blood should be collected at dawn." Lin Chen listed the ingredients:

"In addition, prepare a quiet room and set up a soundproof array so that you are not disturbed in any way during the process."

Su Qingxue nodded, noted everything down, and immediately instructed her servants to carry it out.

In the afternoon, the Su family's intelligence network delivered its first piece of bad news.

A property owned by the Su family in the south of the city was attacked by an unknown force, and the warehouse was burned down. Fortunately, the people had been evacuated in advance.

A faint aura of malevolence was detected in the traces left at the scene.

An hour later, two Su family residences in the west of the city were attacked simultaneously. The attackers were ruthless, and three of the six guards left behind were killed or injured.

The injured recalled that the attackers were all dressed in black robes, moved like ghosts, and used strange and insidious techniques.

"The Netherworld Sect has begun to purge the outer forces of the Su family." In the study, Su Zhenbang's expression was solemn. "They are testing us and forcing us to reveal our weaknesses."

Lin Chen stood by the window, looking at several high points that were vaguely visible outside the manor: "There are already three groups of spies monitoring the area. Their cultivation levels are all around the mid-stage of Qi Refining. They should be peripheral disciples of the Netherworld Sect."

Su Qingxue stood beside him, her gaze icy: "Do you think we should pull it out?"

"No need for now, lest we alert them." Lin Chen shook his head. "The most urgent task is to clear the Yin energy from your body."

"Once it is removed, the Netherworld Sect will lose its most accurate means of positioning, at which point we will be able to advance or retreat at will."

He turned to look at Su Qingxue: "However, when the spell is cast tonight, the Yin Sha Yin will be fully activated, and the Netherworld Sect will definitely notice. They may very well take the opportunity to launch a strong attack."

Su Zhenbang stood up, leaning on his cane, a resolute glint in his eyes: "Although I am old, these old bones can still fight. Tonight I will personally oversee the ancestral home, recall the entire guard team, and activate all defensive formations."

"Grandpa, let me reinforce the formation," Lin Chen said. "My sect has several formations that specifically counter evil spirits; perhaps they will come in handy."

Su Zhenbang cupped his hands in greeting: "Then... I'll have to trouble you, young friend."

For the next half day, Lin Chen set up the cores of the Nine Yang Subduing Demon Formation throughout the Su Family Manor.

The main array was made of Crimson Sun Jade, supplemented by thirty-six jade tablets engraved with runes, which were buried in the four directions of the manor.

Once the formation is activated, it can form a pure yang barrier, which has a strong restraining effect on yin and evil spirits.

Su Qingxue then mobilized her troops, reorganized the guard team, and deployed hidden sentries at key locations.

Although she is young, she commands with composure and has the demeanor of a general.

As dusk fell, all preparations were complete.

Lin Chen and Su Qingxue sat facing each other in the quiet room, with items such as the Crimson Sun Warm Jade and Vermilion Talisman Paper placed between them.

Outside the window, the last rays of the setting sun sank below the horizon, and night spread out like ink.

"It's almost midnight." Lin Chen looked up at the woman opposite him. "Miss Su, are you ready?"

Su Qingxue took a deep breath, a resolute glint in her icy blue eyes: "Let's begin."

She took off her outer clothes, leaving only a thin, plain garment, and sat cross-legged.

Lin Chen mixed cinnabar with pure yang chicken blood and drew a complex yang fire talisman on her chest—that was precisely where the yin evil spirit lurked.

When their fingertips touched their skin, both of them trembled slightly.

At this moment, the Nine Yangs and the Mysterious Yins resonated most directly.

Lin Chen composed himself, placed the Crimson Sun Jade in the center of the talisman, formed hand seals, and chanted a mantra: "Heaven and Earth are boundless, Qiankun borrows the law; Nine Yang True Fire, burn away evil and destroy all evil—Activate!"

The Crimson Sun Jade suddenly lit up, its crimson light spreading along the talisman's patterns and entering Su Qingxue's body.

Almost simultaneously, in a gloomy cave a hundred miles away, Master Youquan suddenly opened his eyes and let out a sinister laugh:

"The Yin Sha Lure has been activated! Su Qingxue, you are finally going to fall completely into my hands!"

He crushed a communication bone talisman:

"All disciples, listen to my command! Target: Su Family Manor! Attack with all your might! Whoever seizes the Profound Yin Body will be rewarded with three Foundation Establishment Pills!"

In the darkness, dozens of dark figures rose into the air from all over Jiangnan, swarming towards the same direction like locusts.

The Su family manor was brightly lit.

The thirty-six jade tablets at the array's focal points emitted a barely perceptible golden glow in the night, interlocking to form a vast, invisible net.

Inside the study in the main building, Su Zhenbang stood with his hands behind his back by the window.

The old man changed into a black outfit, and in addition to his usual pistol, he also wore his ancestral goose feather knife at his waist. His white hair was neatly combed.

"Master, all the sentries are in position." The old guard Su Tie bowed and reported, "As instructed by the young lady, twelve gaps have been left around the manor—seemingly oversights, but actually traps."

Su Zhenbang nodded slightly, his gaze sweeping over the figure standing quietly in the courtyard.

Those were the last thirty-eight guards of the Su family, all dressed in black and carrying swords, with specially made Yang Fire Talismans hanging at their waists.

These talismans were drawn by Lin Chen himself that afternoon, using red cinnabar mixed with red yang warm jade powder, which has the effect of restraining yin energy.

"Uncle Tie," Su Zhenbang suddenly spoke, "how many years have you been with me?"

Su Tie was taken aback: "Forty-two years. When the master rescued me from human traffickers, I was only thirteen years old."

"Yes, forty-two years." Su Zhenbang turned around, a complex expression flashing in his eyes.

"If anything goes wrong tonight, take Qingxue with you. Go to the Murong family in the Northern Border; that's her mother's family, they'll protect her."
