Si Lingle had prepared in advance and took out a White Jade Gourd from her Storage Bag, a "Soul Suppressing Magic Artifact" she had made ready.

Si Lingle shouted in a low voice, "Seal!" The gourd gleamed brightly and a powerful suction pulled the split spirit back into its main body.

The resentful spirit was absorbed into the gourd, and the runes around its opening flickered, sealing it in. Si Lingle sighed in relief, "More troublesome than expected; if it had been fully intelligent, it would have taken more effort."

But the process wasn’t smooth—during the capture, another lurking resentful spirit launched a surprise attack from behind. Si Lingle sidestepped to avoid it but was grazed on the right arm by an arc of electricity, leaving a scorch mark.

Yun Chu operated her Cultivation Technique, and after a short meditation, Immortal Power nourished the wound, causing the scorch mark to gradually fade.

After achieving the mission objective, Si Lingle quickly withdrew from the Thunder Burial Ancient Forest. Along the way, she sensed more restless resentful spirits, and deeper in the forest, louder thunder roars—the disturbance seemed to have alarmed a high-level resentful spirit.

Yun Chu didn’t pause and summoned her Flying Sword, soaring straight into the sky.

As she exited the forest’s edge, dusk had fallen. The rain falling from the thunderclouds carried slight electric currents, sizzling against her Daoist robe.

Si Lingle calculated her rewards: three Thunder Quenching Fruits brimming with Immortal Energy, and the resentful spirit gourd sealed away, worth at least twenty Contribution Points. Along with her other tasks, she was one step closer to gaining access to the Book Collection Peak.

Upon returning to the Thunder Extreme Immortal Sect to submit her mission, the elder from the Artifact Refining Peak took the resentful spirit gourd, eyeing her with slight surprise, "You’re the only new disciple daring enough to venture deep into the Thunder Burial Ancient Forest? This is greatly beneficial for Artifact Refining."

Si Lingle coolly performed a salute, not mentioning her personal experience, merely saying, "Just doing my best for the sect." She turned and left, already planning her next task—the immortal technique tomes on the Book Collection Peak awaited her unlocking.

Si Lingle didn’t delay for a moment and set out the very next day, following the guidance of the mission Jade Scroll, to the "Yin Erosion Swamp" located seven hundred miles southwest of the sect—this place was filled with miasma, and the foul water concealed poisonous insects and demons. The mission required collecting ten stalks of "Bone-Eroding Grass," the main ingredient in the Poison Scripture for crafting Barrier-breaking Pills.

The swamp’s sky was forever shrouded by a lead-gray toxic haze; withered giant trees jutted like sinister bone claws through the water, while the dark green sludge occasionally belched out foul bubbles that released a sickly-sweet stench when they burst.

Si Lingle stood on a half-submerged rotting log, as the Myriad Phenomena Mixed Yuan Unity Cultivation Technique silently circulated within her, decomposing and refining the toxic miasma she inhaled.

With a light flick of her wrist, a condensed Wood Immortal Power transformed into a slender vine whip, precisely wrapping around a Bone-Eroding Grass whose leaf edges emitted a ghostly green glow from the mire.

A seemingly withered "tree knot" on her left suddenly split open, spewing a storm of purple-black Poison Needles!

The needle tips carried the icy aura of corrosive Immortal Power, with an accompanying sharp spiritual screech that pierced straight into her sea of consciousness—a Thorny Demon Vine’s mother body disguised as rotten wood!

Si Lingle swiftly retreated, her vine whip dancing before her to form a green light curtain. The Poison Needles hit the light curtain with a hissing sound, emitting pungent white smoke as the curtain quickly dimmed. 𝑓𝑟ℯ𝘦𝓌𝘦𝘣𝑛𝑜𝓋𝑒𝓁.𝑐ℴ𝓂

The mother body’s root mud churned, and seven or eight black vines covered in barbs burst from the water like giant pythons, sealing off all escape routes.

Even more treacherously, the spiritual screech clung to her mind like a bone-deep ulcer, threatening to shake her Dao Heart.

Just as the rotting wood beneath Si Lingle’s feet was violently shattered by a vine, and her form was about to plunge into the toxic mire—

"Watch out, junior sister! Hold your breath and close your senses!" A clear and urgent female voice rang out.

Immediately, a dazzling red-gold Fire Ring descended from the sky!

Boom!

The Fire Ring accurately ensnared the mother tree knot, erupting in a blaze of sun-pure fire that incinerated the sprayed Poison Needles into wisps of smoke.

The scorching wave expanded outwards, momentarily dispersing the thick toxic miasma and revealing a dim sky.

A figure in a Fiery Red Flowing Immortal Skirt descended swiftly on a blazing Golden Feather Fan, her hands weaving spell changes as she hurled three fist-sized, lava-condensed Fiery Sun Beads at the encroaching vines.

Sizzle! Sizzle!

The moment the Fiery Sun Beads touched the vines, they exploded, with the contained Fire Poison clashing violently against the vines’ inherent poison, emitting a sound like branding iron quenching water, causing the black vines to twitch and retract violently.

The rescuer was clearly an Inner Sect Disciple of the Thunder Extreme Immortal Sect, exhibiting the aura fluctuations of a Late-stage Earth Immortal Cultivation, her beautiful face hinting a pallor, as if bearing hidden wounds.

She forcibly activated the Fire Technique, muffling a groan as blood trickled from the corner of her mouth.

Si Lingle seized the opportunity created, a cold gleam flashing in her eyes. Using one of the retracting vines for leverage, she propelled herself upwards, her hands rapidly forming seals!

"Bind!"

It was no longer merely a defensive Wood Spirit Light Curtain, but an exquisite Killing Technique wielding the fusion of magical concepts and Immortal Techniques—Ten Thousand Forest Prison!
