The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

Shen Yifei felt that this woman's way of speaking was so unappealing, like punching cotton – soft and yielding, yet impossible to counter.

"Third sister, I bet you wouldn't just stand by and watch me die." Shen Yifei chuckled twice. "You know I have the inheritance of the Five Elements Demon God."

The third sister sneered, "So you think you're something special just because you have that guy's legacy? You really think you're Wan Shuo? Once you're dead, his legacy will find another suitable person!"

When Shen Yifei heard his third sister say, "If you die, find another one," his heart sank.

"Third Sister, that's a really heartless thing to say," Shen Yifei chuckled awkwardly. "I'm, after all, Wan Shuo's successor. Can't you be a little nicer to me?"

"I've been good enough to you," Third Sister rolled her eyes at him. "If you weren't chosen by Wan Shuo, would you still be alive today?"

Shen Yifei felt that if this topic continued, he would be close to death.

"Third Sister, that ten-thousand-year-old cold marrow..."

"Ten Thousand Year Cold Marrow?" Third Sister pointed towards the depths of the rift valley. "That thing is at the deepest part of this rift valley. Just follow this path until you reach the end, and you'll see an ice-blue stone. That's the Ten Thousand Year Cold Marrow."

"You can just walk over and get it? It's that easy? Third Sister, please, stop testing me. I've already almost lost my life."

Seeing his cowardly appearance, Third Sister chuckled a few times. "Kid, I'm not lying to you this time. The Ten Thousand Year Cold Marrow is in the deepest part of the rift valley. It won't absorb your soul or bite you. You can rest assured."

Shen Yifei looked at her with suspicion, "Third Sister, if you try to trick me again, I...I..."

"What do you want to do to me?" Third Sister raised an eyebrow. "Hurry up and go. Don't dawdle. If you don't get the Cold Marrow before dawn, that thing will sink to the bottom of the ice and won't reappear until the next full moon."

Upon hearing that there was a time limit, Shen Yifei turned around and jumped into the rift valley without saying a word.

This time, he learned his lesson. With each step, he carefully probed his surroundings with his divine sense, fearing that something else might appear that could drain his soul.

After walking for a while, nothing unexpected happened. At the very end of the crack, there indeed appeared an ice-blue stone.

The stone wasn't very big, about the size of an adult's head, and it looked like a large sapphire.

Shen Yifei moved slowly closer, one step at a time, and after confirming that there was nothing unusual, he reached out and touched the stone.

In Shen Yifei's imagination, the Ten Thousand Year Cold Marrow should feel extremely cold to the touch, since it has accumulated ten thousand years of cold energy.

However, when Shen Yifei touched the stone, he felt a warm sensation.

Is this the millennia-old cold marrow?

Shen Yifei was somewhat suspicious. Could it be that his third sister was using this opportunity to test him?

He grabbed the rock with both hands and lifted it up with all his might.

The stone remained completely still.

"My God, how can such a small stone be so heavy?" Shen Yifei added more force, but it still didn't budge.

Shen Yifei kicked his legs, and the small vortex in his dantian began to spin wildly. All the spiritual power in his body was poured into his arms, but the ten-thousand-year-old cold marrow remained unmoved.

"Damn it, this thing grows in the ground?" Shen Yifei let go of his hand, squatted down, and carefully examined the bottom of the Cold Marrow.

There was no sign of connection between the stone and the ice surface; it looked as if it were simply placed on the ice. Yet, it couldn't be moved, as if an invisible force was holding it down.

"Brother, you can't pull it out. The Ten-Thousand-Year-Old Frost Marrow is one with the entire Frost Ruins; pulling it out is equivalent to pulling out the entire Frost Ruins!"

Xinghe's words made Shen Yifei suddenly realize why he couldn't lift it. With his strength, he could even turn over a small mountain in front of him.

"Xinghe, what should we do?"

"Master, ask this stone if it's male or female. If it's male, beat it up; if it's female, seduce it."

"Mengli, can you be serious for once? This thing is a rock, it doesn't even have a crack, what's the difference between male and female?"

"Master, you're wrong about that," Liu Mengli said seriously inside the cauldron. "All things in heaven and earth have a spirit, let alone a treasure like the Ten-Thousand-Year Cold Marrow."

"Mengli, what are you thinking about all day long? You even go after stones?"

"Brother, what Sister Mengli said seems to make sense. It can absorb ten thousand years of cold energy on its own, and it can only appear on the night of a full moon. Isn't that a sign of intelligence?"

After Xinghe's suggestion, Shen Yifei realized that it was indeed true.

"Then tell me, how am I supposed to tell if it's male or female?"

"Master, touch it and see if it reacts. The male stone will be hard, and the female stone will be soft."

Although Shen Yifei didn't believe Liu Mengli's words, he still unconsciously touched the Cold Marrow.

"The males are rock hard, the females are soft and fluffy..." Shen Yifei muttered. "How do you tell the difference? When I touch this thing, it's neither hard nor soft..."

"Master, try sending your soul in!" Liu Mengli continued to offer bad advice. "Since this Northern Underworld Land values ​​the soul, go in and try to feel it. Treat it like a woman, and you might be able to communicate with it."

Shen Yifei had no other choice but to try anything, so he separated a wisp of his soul and carefully probed into the interior of the Ten Thousand Year Cold Marrow.

I never expected that the Ten Thousand Year Cold Marrow would have such a unique feeling.

It is hard and cold on the outside, but warm and moist on the inside.

The space inside the Cold Marrow was vast, and Shen Yifei's soul wandered aimlessly within it.

After wandering around inside for an unknown amount of time, Shen Yifei actually spotted someone.

A woman!

The woman was completely naked, her long hair falling loose and covering half her face. Her eyes were closed, and her breathing was even, as if she were asleep.

When Shen Yifei saw the woman, his soul was suddenly jolted.

"My goodness, Liu Mengli was absolutely right!"

After stabilizing his mind, Shen Yifei looked at the woman more closely. Her appearance was not very clear, and she was blurry, as if she were looking through a thin veil.

He tried to communicate with the woman using his spiritual senses, "Hey... hello... can you hear me?"

The woman showed no reaction whatsoever.

He shouted several more times with his mind, but there was still no response.

"Is this a living person or a dead person?" Shen Yifei muttered, his spirit moving forward further to try and see the woman's appearance more clearly.

As Shen Yifei's soul drew closer, the woman's outline gradually became clearer.

The woman was lying on her side with her legs crossed and her arms wrapped around her chest, revealing nothing that should be covered.

Shen Yifei thought to himself, "This pose is truly perfect!"

The woman was extremely beautiful, with exquisite features that looked like they were carved from ice and jade. She had fair skin, long, black hair, and exuded a cold and aloof aura.

There was a light blue mark between her eyebrows, shaped like a snowflake, with a faint shimmering light.

Shen Yifei couldn't help but stare at her for a while longer. No matter how he looked at her, this woman didn't seem like an ordinary person. This was probably what a fairy from the celestial realm looked like.

Because time was limited, Shen Yifei was afraid that if it got light, he would have to wait for the next full moon. Otherwise, even if he stood there quietly for a whole day, he wouldn't get enough of watching it.

He cleared his throat and said softly, "Miss, can you hear me? I mean no harm. I just want to borrow a bit of the Ten Thousand Year Cold Marrow."

Unexpectedly, his gentle words had an effect.

The woman slowly opened her eyes.
