Lin Zheyu's cold voice rang out.

"Move, and you die!"

The woman's body stiffened, and the surging spirit power within her came to an abrupt halt.

"D-Don't kill me!" the woman said, her voice trembling with fear.

Lin Zheyu snorted softly, gripping the woman by the neck. In an instant, he vanished, and when he reappeared, he was already over a hundred kilometers away.

Lin Zheyu rummaged through her belongings, pulling out several storage pouches, and said calmly, "Open them." 𝐟𝐫𝕖𝗲𝘄𝚎𝗯𝕟𝐨𝕧𝐞𝚕.𝕔𝕠𝐦

The woman did not hesitate. With a movement of her spiritual sense, the storage pouches opened at once. She was sensible enough to erase the spiritual sense imprints inside them as well. Her level of cooperation surprised Lin Zheyu slightly.

"Name, family, strength..." Lin Zheyu said flatly as he inspected the storage pouches taken from her.

"This humble one is Mu Yin, under the Directorate of Celestial Observation, late-stage Foundation Establishment realm..." Mu Yin replied hurriedly.

She hid nothing and poured everything out in one breath. Mu Yin did not want to die. She had endured countless hardships to reach the late-stage Foundation Establishment realm. If she were to die here just like this, she would never accept it!

Lin Zheyu listened without expression. He only treated her words as reference and did not fully believe them. What surprised him most was that she was actually at the late-stage Foundation Establishment realm.

Are cultivators at this level really so weak? So I've already become this strong? Lin Zheyu muttered inwardly.

A supposedly powerful late-stage Foundation Establishment realm cultivator was as easy for him to deal with as slaughtering chickens and dogs, which spoke volumes of his strength. Of course, it was also possible Mu Yin was simply weak for her level. He shook his head slightly, not dwelling on it, and asked calmly, "What did you use just now to bypass my perception?"

"White Flow Jade," Mu Yin replied in a soft, delicate voice.

Her voice carried a faint, breathy quality that stirred a tingling sensation upon hearing it. At the same time, her appearance began to change. Her disguise vanished, revealing a fair, fox-like, alluring face. She looked at Lin Zheyu with pitiful eyes. With a slight circulation of spirit power, her clothes shifted into thin gauze, her full and enticing figure faintly visible beneath.

Lin Zheyu observed her figure with interest. It had to be said that these immortal cultivators maintained themselves well. Nourished by spirit power, their appearances were all exceptional.

Lin Zheyu took out the warm jade he had just retrieved from her and asked curiously, "So this is White Flow Jade?"

"That's right," Mu Yin replied softly. A trace of doubt flashed in her heart, as if she found it strange that Lin Zheyu did not recognize it.

Seeing the confusion in Lin Zheyu's eyes, Mu Yin explained, "White Flow Jade is a powerful concealment-type dharma artifact. Each piece can only be activated ten times. After ten uses, it loses all effect. This kind of jade is extremely expensive. One piece costs a mid-grade spirit stone."

She blinked, her beautiful eyes moving as they swept over him, as if trying to see through him.

A demon cultivator? No, impossible. The aura he released in battle wasn't that of a demon cultivator. Could it be some special secret technique? Mu Yin's thoughts raced.

After confirming he was not a demon cultivator, Mu Yin relaxed slightly. That was also why she had been so cooperative. As long as he was not one of those mad demon cultivators, there was still a chance to survive.

"White Flow Jade? Interesting." Lin Zheyu showed a trace of surprise.

This kind of dharma artifact was indeed remarkable, but far too expensive. One piece cost a mid-grade spirit stone and could only be used ten times.

After checking all the storage pouches he had taken from Mu Yin, his brows furrowed slightly and he asked coldly, "Only one?"

"We obtained it earlier in a demon cave from a fallen expert. When we found him, he was already dead, likely killed by a powerful yao. This White Flow Jade came from that senior," Mu Yin explained hurriedly.

Lin Zheyu frowned. He had found nothing of value in the storage pouches. There were no jade slips, nor any technique manuals.

"Senior, please don't kill me. I possess a Profound Yin physique. The Profound Yin Cauldron King Technique I cultivate can accelerate spirit power absorption and purify it through dual cultivation," Mu Yin said quickly in a soft voice when she saw the unfriendly look on Lin Zheyu's face. Her waist swayed, and a faint seductive aura spread from her.

"Do you know formation arts?" Lin Zheyu asked calmly.

"No."

"What about alchemy?"

"No."

"Restrictions?"

"Um... still no..." Mu Yin replied weakly.

Lin Zheyu was speechless. It seemed this woman had been raised more as an aid to cultivation than anything else. He took out a blank jade slip from his own storage pouch and tossed it to her. He had prepared well for this trip. While wandering outside Ruyang City, he had come across some and bought a few jade slips for later use. Ordinary jade slips only cost five low-grade spirit stones, which he could easily afford.

Lin Zheyu let out a cold laugh, his tone icy as he said, "Record all the techniques you know. Don't tamper with them, or..."

Mu Yin caught the jade slip and responded quickly, "Yes, yes, I wouldn't dare!"

She could tell that this powerful senior had no interest in her Profound Yin physique. In ancient times, such a physique held many profound benefits. Its primordial Yin could even aid in breaking through to the Golden Core realm.

But the Immortal Dao had changed. Most of those effects were lost, leaving only its function as a cultivation aid, and even that was only useful to low-level cultivators. For someone as strong as him, it was natural to dismiss it.

She pressed the jade slip to her forehead, her spiritual sense flowing into it. After more than ten minutes, Mu Yin finally opened her eyes, looking exhausted. Recording information onto a jade slip consumed a considerable amount of spiritual sense, especially with the low-quality slips Lin Zheyu had bought. The poorer the material, the harder it was to record and the shorter the preservation time.

"Senior, these are all the techniques I know. The Profound Yin Cauldron King Technique was exchanged from the Directorate of Celestial Observation. It was placed under restrictions upon exchange, so it cannot be passed on. Please forgive me," Mu Yin said respectfully.

Seeing that Lin Zheyu remained unmoved by her attempts, she restrained herself and put on a pitiful expression. Lin Zheyu glanced at her indifferently and sent his spiritual sense into the jade slip. Instantly, five different techniques came to mind. All five were spells and divine abilities, not cultivation techniques. After a quick look, he shook his head slightly, disappointed.

Lin Zheyu put away the jade slip and asked coldly, "No soul secret arts?"

"Soul secret arts are extremely rare. Even if you want to buy them, it's hard to find any channel," Mu Yin replied quickly.

"Oh." Lin Zheyu responded lightly.

Just as he expected, soul secret arts were not easy to obtain. There was little of value in Mu Yin's storage pouches, and she clearly lacked any strong backing. It was normal that she did not possess such arts.

Next, Lin Zheyu continued asking questions. He inquired about how to use Divine Power Crystals, the cultivation forces within Great Wei, and the locations of various immortal markets. Though Mu Yin's eyes were filled with confusion, she answered everything she knew without holding back. Her level of cooperation almost made Lin Zheyu feel embarrassed to kill her.

"Alright, you can go," Lin Zheyu said calmly.

Surprise and joy flashed in Mu Yin's eyes as she quickly expressed her gratitude, "Ah! Yes. Thank you, Senior! Thank you!"

She spun around, and her escape light flared. The excitement in her eyes vanished in an instant, replaced by a dark and sinister expression.

Pfft!

Suddenly, her expression froze, and her body exploded on the spot. Lin Zheyu's figure fully materialized behind her.

Lin Zheyu shook his head slightly and murmured, "So it was all an act. You were so cooperative, I almost didn't want to kill you."

Mu Yin had been too cooperative, answering many of his doubts. Lin Zheyu had genuinely considered sparing her. Unfortunately, she failed to seize that chance. If Mu Yin knew his thoughts, she would surely cry injustice. The dark, sinister look she showed earlier had only come from losing everything she had worked so hard for. It was not directed at Lin Zheyu at all. Facing someone so overwhelmingly powerful, she had not even a trace of resistance or revenge in her heart.

Lin Zheyu's figure flickered and vanished from the spot. As he traveled, a Divine Power Crystal appeared in his hand. After hesitating for a moment, he shook his head and put it away again.

The method Mu Yin described required using blood as a medium, engraving sacrificial inscriptions onto the Divine Power Crystal, and injecting spiritual sense and spirit power to establish a connection with divine power.

Lin Zheyu did not trust Mu Yin. Even if the method worked, he had no intention of trying it. It felt too strange and deeply unsettling.
