The cool breeze blew gently, night had fallen, and the stars dotted the sky.
Lin Xinghe lurked in the shadows, her heart hammering like a drum.
Ahead of her, Lin Feng and a mysterious figure were whispering together, their figures appearing eerie and sinister in the dim light.
"The launch of the Netherworld Plan is set for the eighth of next month," the mysterious figure rasped in a hoarse, low voice, sounding like a whisper from the depths of hell. "We must ensure everything is foolproof by then."
Lin Feng nodded slightly. "Everything is proceeding according to plan, but..." He paused, seeming somewhat hesitant. "As for Lin Xinghe..."
"No need to worry," the mysterious figure sneered. "She is just a wet-behind-the-ears girl who can't stir up any major waves. Even if she discovers something, she is powerless to stop us."
A chill struck Lin Xinghe's heart. The four words "Netherworld Plan" exploded in her mind like a thunderbolt.
She recalled fragments of conversation she had accidentally overheard earlier, which seemed related to some kind of taboo art.
If this plan were truly launched, the consequences would be unimaginable.
She clenched her fists, a strong sense of unease surging into her heart.
She had to improve her strength as quickly as possible if she wanted to prevent this disaster from happening.
The night grew heavier, and Lin Xinghe slipped into the Sword Tomb Secret Realm once more.
Starlight filtered through the dense woods, casting mottled shadows on the ground like an entrance to another world.
She found Yun Wufeng and poured out all her discoveries and worries.
After listening, Yun Wufeng's expression turned grave. "The Netherworld Plan—this is no trivial matter. You did the right thing; we must stop them." He pondered for a moment. "The fifth-layer Sword Soul contains immense power, but absorbing it also carries huge risks. Are you sure you want to do this?"
Lin Xinghe nodded without hesitation. "I must grow stronger, in order to protect everything I cherish."
Yun Wufeng looked at her deeply, nodded, and led her to the Sword Soul Cavern.
Deep within the cavern, five multicolored beams of light interwove and shone upon one another—the energy fluctuations emitted by the five layers of the Sword Soul.
Lin Xinghe took a deep breath, feeling the overwhelming pressure rushing toward her.
Each layer of the Sword Soul was like an insurmountable barrier blocking her advance.
The first-layer Sword Soul was like a gentle breeze brushing the face, soft and soothing.
The second-layer Sword Soul was as heavy as a mountain, steady and firm.
The third-layer Sword Soul was as scorching as a blazing fire, violent and fierce.
The fourth-layer Sword Soul was as agile as flowing water, unpredictable and ever-changing.
When Lin Xinghe tried to touch the fifth-layer Sword Soul, a powerful repulsive force beat her back.
Her body trembled violently, as if it were about to be torn apart.
"Ah!" Lin Xinghe groaned in agony, beads of sweat rolling down from her forehead.
She felt her consciousness begin to blur, as if she were about to be swallowed by darkness.
Just as she was about to give up, a familiar voice rang in her ear: "Xinghe, hold on!"
It was Baili!
Baili's figure appeared before her, radiating a soft glow.
She reached out, gently stroking Lin Xinghe's cheek, offering her encouragement and support.
"Xinghe, I know you are in pain, but you must keep going. There is immense potential hidden within you; you can definitely do it!" Baili's voice was gentle yet firm, like a warm current pouring into Lin Xinghe's heart.
Lin Xinghe clenched her teeth, once again gathering all her strength as she charged toward the fifth-layer Sword Soul.
This time, she felt her body become much lighter, as if an invisible force were pushing her forward.
She broke through the first-layer Sword Soul, the second-layer Sword Soul, the third-layer Sword Soul, the fourth-layer Sword Soul...
Finally, she touched the fifth-layer Sword Soul!
A mighty surge of energy poured into her body, as if it were going to burst her apart.
Her body shook violently, emitting a dazzling radiance.
Lin Xinghe slowly opened her eyes, feeling an unprecedented, powerful force surging within her.
Lin Xinghe continued to play the role of a lowly maid of the Lin Family. The dust and coarse cloth concealed the surging Power of the Sword Soul within her body, and also veiled her sharp gaze.
She melted into the Lin Family like a drop of water in the ocean, silently observing everything about them, especially Lin Feng.
The warning in the anonymous letter lingered persistently in her mind, acting like a taut string that constantly reminded her of the lurking danger.
She remembered Yun Wufeng's teachings in the Sword Tomb Secret Realm: power is not meant for showing off, but for protection.
And now, what she needed to protect was not just her own life, but also countless innocent people shrouded by the "Netherworld Plan."
On the surface, the Lin Family was calm and peaceful, but underneath, unknown undercurrents surged.
Lin Xinghe acutely caught some subtle changes.
Lin Feng's whereabouts had become erratic, and he frequently frequented the Forbidden Land of the Lin Family late at night.
His conversations with the family head, Lin Zhentian, also grew more frequent, their words always carrying a hint of imperceptible tension.
What on earth was the "Netherworld Plan"?
Lin Xinghe repeatedly pondered this question.
She had tried searching the Scripture Pavilion for clues, but found nothing.
Records concerning family secrets in the Scripture Pavilion were sparse, as if someone had deliberately erased them.
Lin Xinghe was not discouraged; she knew well that the truth was often hidden in the most inconspicuous places.
She began paying attention to the conversations of the Lin Family servants, piecing together scattered information from their stray words.
She learned that the Lin Family had recently been secretly recruiting martial artists and had stepped up the excavation of the mine veins.
All these signs indicated that the "Netherworld Plan" was underway in full swing.
At the same time, Lin Xinghe was also secretly improving her strength.
Every day she set aside time to practice the sword techniques taught by Yun Wufeng, integrating the power of the fifth-layer Sword Soul into every move and stance.
She understood that only by possessing sufficient strength could she remain undefeated in the impending storm.
Late one night, Lin Xinghe was lurking outside Lin Feng's study, trying to eavesdrop on his conversation with Lin Zhentian.
Suddenly, a powerful aura emanated from afar, startling her.
This aura was cold and eerie, completely different from any aura she had previously felt.
Lin Xinghe held her breath, completely concealing her presence.
Through a crack in the window, she saw a mysterious person draped in a black cloak walk into Lin Feng's study.
The person's face was hidden in the shadows of the hood, making their features indistinguishable, but Lin Xinghe could feel the dangerous aura radiating from them.
Upon seeing the figure in black, Lin Zhentian immediately stood up and bowed respectfully, his tone deferential: "Emissary, you have finally come."
"How is the progress of the Netherworld Plan?" the figure in black asked, voice hoarse like the cry of a Yexiao.
Lin Zhentian hastily replied, "Everything is proceeding according to plan, only..." He hesitated, seeming to have some unspeakable difficulty.
"Only what?" A hint of impatience laced the figure's tone.
Lin Zhentian glanced at Lin Feng, who immediately understood, walked up to the figure in black, and whispered a few words in their ear.
Upon hearing this, the figure in black let out a cold laugh. "It seems we still need some special 'sacrifices'."
Lin Xinghe's heart sank, an ominous premonition welling up within her.
"Sacrifices"?
This word made her hair stand on end.
She realized that the "Netherworld Plan" was far darker and more cruel than she had imagined.
The figure in black conversed in low tones with Lin Zhentian and Lin Feng for a moment longer before quietly departing.
Lin Xinghe watched the figure of the person in black vanish into the night, her heart filled with doubt and unease.
She vaguely sensed that she was stepping ever closer to the core of the truth, yet she was also facing even greater danger.
Lin Xinghe continued to track Lin Feng, attempting to find more clues regarding the "Netherworld Plan" and the mysterious figure in black...
