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

"Demonic energy?" Chu Lengyu murmured softly.

It seems that this was the source of her sudden impulse yesterday evening.

The black mist was slightly surprised to have its origins exposed.

What surprised him even more was that this young man opposite him was already at the third level at such a young age, and he was in such a world.

It's like a pure lotus flower suddenly blooming in a parched, cracked patch of land, standing out from the crowd.

In the blink of an eye, their eyes met, and without a word, they were already enemies, and they attacked simultaneously without hesitation.

Chu Lengyu drew her longsword, its light as bright as the moon, transforming into more than ten crescent-shaped silver streaks that intertwined to form a net, firmly sealing off the surrounding space.

The demon, however, paid no heed. He casually spat out a dark gourd, its mouth wide open, and in an instant, black mist filled the air, obscuring the sky and completely engulfing Chu Lengyu's consciousness.

With a thought, Chu Lengyu conjured a spiritual shield that protected her.

With a flourish, she resembled a dragon emerging from the sea, soaring straight into the sky, as if trying to break through the layers of mist.

However, the mist seemed to possess a spirit, spreading and following her, trapping her firmly and making it impossible for her to discern her direction.

The demon watched her dash through the mist and sneered from the side, "Just give up and surrender, and maybe I'll leave you with a whole corpse."

The sound echoed in the mist, cold and eerie, as if it came from the depths of hell, sending chills down one's spine.

Moreover, it is sometimes near and sometimes far, unpredictable and difficult to pinpoint its true location, making it impossible to discern the exact location where the demon is hiding.

Chu Lengyu's expression was solemn, and she was secretly on guard. She put away the slight complacency that arose from her successful tribulation. She did not expect that she would suffer a loss right from the start due to her lack of combat experience.

However, now is not the time for reflection; she only needs to think about how to deal with the enemy.

The demon spoke sternly, seemingly not taking her seriously, but in reality, he knew that he was currently severely injured and that Golden Core cultivators were not so easy to deal with, so he kept a close eye on Chu Lengyu's movements.

Moreover, he realized that his clone had met with misfortune, which made him even more vigilant.

The demise of that clone was most likely the work of the woman before him, indicating that she possessed some means that could threaten him. How could the demon not be wary of her?

He decided to put more pressure on her to force her to reveal her true abilities. He exerted his strength once more, spitting out two curved blades, one gold and one silver, which flew into the mist to chase after Chu Lengyu.

The two curved swords are also third-tier magic weapons, with sharp attacks and perfect coordination.

Chu Lengyu used her escape technique to avoid the attack, but she was already eyeing the demon's storage bag.

The system said that there would be enough materials in this world for her to use in the future.

Now it seems that I was right.

This demon is quite wealthy, and can use magical treasures one after another to fight his enemies.

However, this also proves that he is by no means easy to deal with.

Chu Lengyu had a plan in mind, but she didn't show it on her face. She just focused more on dealing with the curved blade's attack. She knew that only by stabilizing her position could she find an opportunity to counterattack.

Seeing this, the demon was secretly pleased with himself.

He thought Chu Lengyu was just a "native" female cultivator. Although her cultivation was not low, her methods were limited. She was already at her limit, having been chased so badly by the curved blade magic weapon he released.

He became even more convinced that this world was devoid of spiritual energy and resources, making it difficult to nurture true powerhouses.

This woman has already reached the Core Formation stage, which means she must be at the peak of this world and a remarkable figure. Yet, she only has a spiritual sword to fight against.

It seems that this world is nothing special, and there is nothing that can threaten him.

“Your soul should be much stronger.” The demon looked at her and muttered greedily to himself, “Once I capture you, search your soul and seize your spirit, I will have all the information in this world. I wonder how much trouble that will save me.”

In that case, he should thank her for walking into his trap.

"clang!"

The Lone Sword clashed with the golden scimitar magic weapon again. Although the golden scimitar was powerful, it was still knocked away by the Lone Sword's sharp sword light.

However, the silver scimitar silently circled around from below, attempting to launch a surprise attack and achieve victory.

Chu Lengyu reacted quickly, hastily setting up three layers of spiritual energy shields and retreating rapidly.

The shield that Fu Wenshen could not break through no matter what was done was extremely fragile in front of the curved blade magic weapon, as thin as paper, and could only slightly delay its attack.

But that brief moment of hesitation was enough for a Golden Core cultivator to react.

Chu Lengyu seized the opportunity and released the Heavenly Net Umbrella, which was now almost just a frame. The silver curved blade rushed straight at her, unable to turn around or retreat, and could only fall into the center of the umbrella.

The umbrella frame closed quickly, trapping it inside temporarily.

However, the Heavenly Net Umbrella was severely damaged under the lightning tribulation, and its ability to trap the curved blade magic weapon for a short while was its limit.

With only a golden scimitar remaining, Chu Lengyu felt a significant reduction in pressure and drew her sword to meet the attack.

Upon seeing this, the demon immediately devoted more of his attention to controlling the golden scimitar to fight against her.

With him in control, the golden scimitar suddenly became agile, no longer just charging around aimlessly as before.

Since Chu Lengyu transmigrated, this was the first opponent she had encountered, and the first battle she had fought.

Moreover, whether the demon was seriously injured or overly cautious, he did not reveal himself to fight her with all his might. This was the perfect opportunity for her to test her cultivation and hone her sword skills.

She was in high spirits, constantly demonstrating various sword techniques to compete with him.

She usually practiced swordsmanship alone, working in isolation without ever achieving perfection. Now that she had finally met a worthy opponent, she was overjoyed and kept changing her moves, testing them in her mind.

This trick looks cool but isn't practical.

The upward movement of this move is too obvious; the opponent will dodge it.

This move has a long recovery time, making it easy for opponents to exploit openings.

This move is too slow, this move isn't concise enough, this move is okay but can be improved...

Chu Lengyu constantly observed, thought, and summarized, adjusting her moves and deeply imprinting each practical experience into her mind.

Her face gradually paled, but her eyes grew brighter and brighter, and the sword light she unleashed became purer and purer, with many complexities removed.

Her progress in battle was nothing short of miraculous.

The demon noticed that she was getting more and more energetic as she fought, as if she was using him as a sparring partner. He couldn't help but feel annoyed. He wasn't her senior from her sect, and he wasn't there to give her pointers!

The golden scimitar suddenly erupted with a violent surge of spiritual energy.

Chu Lengyu reacted quickly, forming hand seals to create a spiritual energy shield.

Even so, the immense force still caused her to involuntarily slide back quite a distance before she could barely regain her balance.

However, the demon did not take this opportunity to launch a sneak attack. He looked at Chu Lengyu's pale face, grinned, and released a hundred blood threads that slithered towards her.

He thought smugly: This mist contains a demonic poison, colorless and odorless, that can poison people without them even realizing it. In his hands, it has never failed.

However, he naturally wouldn't kindly point it out and remind the female cultivator that she had been poisoned; instead, he was prepared to enjoy her struggle and despair.

These blood vessels twisted and swirled in the air, like hungry venomous snakes, rushing toward Chu Lengyu as if they couldn't wait to devour her flesh for nourishment.

Chu Lengyu's face was as cold as frost, and her eyes were icy.

After dealing with him for so long, it's about time.

She bit down on the Shennong Herbal Pill that she had been holding in her mouth, and the abundant medicinal power surged out instantly, sweeping through her limbs and bones, completely healing the minor injuries she had suffered during her tribulation and the demonic poison she had inadvertently inhaled in the mist.

Therefore, elixirs are truly indispensable.

She was distracted and thought: I should urge Master Lu again later, because time is running out.

He gripped the Lone Sword tightly, ready to strike, and swung it horizontally in a dazzling arc. Silver light burst forth, repelling the persistent blood vessels, but failing to eliminate them all at once.

The severed blood vessels split in two, yet still greedily surged towards her.

Chu Lengyu paid no attention and raised her sword again, as if swatting mosquitoes. However, these blood streaks were condensed with the power of blood and qi, making them extremely strange and difficult to annihilate.

The demon lord watched the show leisurely from outside the mist, observing the flashing sword lights, until Chu Lengyu drew closer and closer, at which point he suddenly realized something was wrong.

But it was too late.

A silver sword light appeared before him as if it had traveled through time and space, its radiance flowing, beautiful yet deadly.

She acted for so long just to deliver this one blow to him.

The third move of the Moon-Slaying Sword Technique: Flowing Moonlight!
