My low-key cultivation of immortality was discovered by the emperor in my diary.

Chu Wen'er familiarized herself with her newly acquired "power".

This black mist looked terrifying and ominous, definitely not benevolent, but she was now only focused on revenge and didn't care whether it was good or evil.

Looking around the room, the hiding place was simple yet secluded. Chu Wen'er sighed softly, blew out the oil lamp, and pushed open the wooden door.

Outside the door, snow was falling heavily, covering everything in a vast expanse of white.

Chu Wen'er's gaze swept around, searching for that familiar figure, but all she saw was a vast, empty snowfield.

Her brother, Chu Lin, actually left alone, without waiting for her outside.

A complex mix of emotions welled up within her: disappointment, anger, sadness, and a barely perceptible sense of relief.

But she quickly suppressed these emotions, a cold smile playing on her lips.

Her brother was cowardly and incompetent. Faced with a blood feud, he only thought about escaping and protecting himself. She was ashamed to be associated with him!

It's better to part ways like this today, let my brother escape for his life.

She will prove to her parents in heaven that she was right.

Stepping into the vast snowstorm, Chu Wen'er moved as lightly as a swallow, leaving no trace on the snow. The magical power within her made her temporarily forget the cold, and she felt surrounded by warmth.

She lifted her trailing skirt and tried to take steps, even jogging. Chu Wen'er was pleasantly surprised to find that her speed had exceeded her expectations.

"Is this my power?" Chu Wen'er thought to herself with secret pride, her eyes gleaming with confidence.

This power will become the sword of her revenge.

"Chu Lengyu, you just wait!" she vowed silently in her heart, then quickened her pace and disappeared into the wind and snow.

And in the pale snow, the cold wind continued to blow.

Like weeping and lamenting, like an endless dirge.

Crimson blood dripped onto the pristine white snow, like dazzling red plum blossoms.

Chu Lin's body was hanging on a tree in front of the house.

His face was contorted in terror.

Those once bright and warm eyes were now wide open, their pupils almost bursting, as if telling of the endless fear before death.

His gaze remained stubbornly fixed on the direction where his sister had left; that was where his last concern and reluctance lay.

Deep within the shadows of the forest, an even larger and deeper mass of black mist lies hidden, silently lurking.

It extended a long, slender, and twisted tentacle, which tightly wrapped around Chu Lin's body.

With each wriggling of the tentacles, the flesh and blood within Chu Lin's body seemed to be drawn away by an invisible force, turning into nutrients in the black mist, nourishing that indescribable and terrifying being.

As it absorbed the energy, the red streaks within the black mist became increasingly prominent.

They moved through the mist like living creatures, and just by looking at them, one could smell the nauseating stench of blood.

Chu Lin's body rapidly lost its vitality under this constant draining. His skin became abnormally pale, losing its former color and luster. It was as if his bones and marrow had been sucked dry, leaving him completely drained.

His body began to wither and shrink until the thin skin could no longer support him, and was finally pierced and torn apart by the bare bones.

Then, chunks fell one after another, hitting the thick snow with only a soft thud.

He died just like that, silently and without a trace.

Torn to pieces, his body left to rot in the wilderness, he was no longer recognizable as the once spirited young man.

In the depths of that dark shadow, black mist slowly writhed in an eerie manner, seemingly harboring endless malice and greed.

It let out a low laugh that echoed through the silent forest, sending chills down one's spine.

Then, in a condescending tone, it commented on Chu Lin's plight: "I finally found a usable 'container' in this barren land, how could I let you ruin it? Hmph, it is your and your sister's good fortune to be able to offer everything for me!"

The mist dispersed, like a giant opening its mouth, taking a deep breath as if it could devour everything, including the surrounding cold wind and snowflakes.

"Ah, this world is truly wonderful. So beautiful, so pure, like a virgin, untouched by any defilement. This feeling is intoxicating."

"The only drawback is that the spiritual energy here is far too thin. But even so, I am quite satisfied with the integrity of this world."

"As long as I can find the weak point in the barrier of this world, break through that barrier, establish a passage, and bring my fellow demons to this place, then this world will no longer be able to maintain its purity and peace, hahahahaha!"

At this point, the voice of the black mist was filled with fervor and anticipation.

"Imagine what it would be like if the Demon Lord himself descended upon this complete and pure world! He would surely reward me handsomely!"

As it uttered wild and absurd words, it caused the black mist to slowly spread out, like an invisible giant net, covering the entire forest.

The evening clouds are heavy, for an unprecedented catastrophe is about to descend.

……

In the Pine Forest Cottage.

Chu Lengyu's hand, hanging by her side, suddenly trembled at the fingertips, causing her heart to flutter.

On a whim, she leaped into the air, hovering high above, gazing at the vast, distant horizon.

With limited spiritual sense at the Foundation Establishment stage, she didn't notice anything unusual. She simply pursed her lips and furrowed her brows slightly.

A cultivator's sudden impulse is fleeting, but it should not be underestimated. It must be something related to her that has already happened or is about to happen.

"I should try to overcome this tribulation as soon as possible," she muttered to herself.

After entering the Golden Core stage, her spiritual power will be more abundant, enabling her to refine magical treasures and accomplish more.

Chu Lengyu analyzed her situation and concluded that her biggest problem was that her methods were too limited.

The Dubu Sword is excellent, but it is only good for offense.

The system's diary rewards are too random and cannot be relied upon entirely.

It seems she needs to complete that task as soon as possible and obtain the Nine Provinces Town Cauldron. Although this ancient treasure has its drawbacks, it is comprehensive in function and is at least enough for her to use from the Golden Core stage to the Nascent Soul stage.

Afterwards, she will go to Wushan to see how much heritage the local cultivators have accumulated over the past thousands of years, and perhaps she can gather it and make it her own.

As for the spiritual plant cultivation plan, it will be continued by Master Lu. Once this part is successful, the entire system envisioned by Chu Lengyu will have a foundation, and the rest will have the confidence to be implemented.

Alchemy, weapon crafting, talismans, formations, Gu techniques, beast taming... the methods in the cultivation world are so diverse.

Perhaps thousands or tens of thousands of years later, a golden age of cultivation will emerge in this world.

She pondered quietly, her gaze fixed on the distant capital city.

Everything must begin with the Great Xia Dynasty.
