The Thunder Burial Ancient Forest is located three hundred miles southeast of the Thunder Extreme Immortal Sect, a desolate area eroded by lightning throughout the year.

Legend has it that this was once an ancient battlefield where immortals underwent tribulation, countless cultivators perishing here, leaving scorched earth and a sinister atmosphere.

The ancient forest is perpetually shrouded under gray thunderclouds, the air filled with the pungent smell of charred vegetation and metal, with occasional blue arcs of electricity crackling in warning.

Si Lingle arrived early on her sword, dressed in the sect’s gray Daoist robe, a Jade Token symbolizing an inner sect disciple hanging from her waist, tightly gripping a task Jade Scroll in her hand.

Her objective was to collect three "Thunder Quenching Fruits" and capture at least one "Tribulation Ash Resentful Spirit" — the former being a scarce material for the Alchemy Peak, the latter exchangeable for contribution points at the Artifact Refining Peak.

Upon landing, Si Lingle walked cautiously on the charred soil, her boots making a rustling sound.

The surrounding trees had long carbonized, twisted branches reaching skyward like ghostly claws, the ground strewn with obsidian-like rubble, each step avoiding hidden Thunder Patterned traps.

The task Jade Scroll mentioned that Thunder Quenching Fruits only grow in the core area of the Heavenly Tribulation, namely those scorched pits blasted by high-intensity lightning strikes.

Such places often retain a violent lightning force, difficult for ordinary people to approach.

Si Lingle operated the "Myriad Phenomena Mixed Yuan Unity" cultivation technique, letting the immortal power within her circulate like a stream, absorbing the surrounding dim glimmers of lightning into her meridians, converting it to her energy. She took a deep breath, released her Divine Sense to scan the surroundings, quickly locking onto several areas with strong lightning fluctuations.

The first scorched pit lay beneath a cliff, more than ten zhang in diameter, with the pit’s bottom covered in a layer of crystalline purple moss.

As Si Lingle approached cautiously, sensing the electric resistance, she swiftly sealed, her two fingers drawing out a wood element barrier — though she now focused on immortal techniques, her early training in the Magic World had forged wood element instincts as her auxiliary means.

The barrier absorbed the crackling electric arcs, and Si Lingle seized the opportunity to jump into the pit.

Cracks covered the pit walls, faint remnants of resentful spirits flickered in the crevices like phantoms, not yet forming entities. Ignoring these disturbances, she focused her gaze on the center’s plants: they stood about one chi high, with sword-like leaves, their tips suspending fist-sized, blue-violet fruits, precisely the Thunder Quenching Fruits. Fine arcs of electricity danced on their surfaces, three hundred years of tribulation power condensed within.

Si Lingle took out a specially made Jade Bottle, softly reciting the Capture Technique. As she picked the first Thunder Quenching Fruit, the scorched earth beneath her feet suddenly trembled!

Dozens of Thunder Serpents burst from the pit, winding towards her — the residual mechanism of the Guardian Demon Beast "Thunder Patterned Spider."

Yun Chu reacted swiftly, toe-tapping the ground to leap into the air, while the wood element immortal power transformed into green vines coiling towards the Thunder Serpents.

The Thunder Serpents were absorbed by the vines, vanishing instantly. She successfully collected three fruits, placing them into her Storage Bag.

The entire process took less than half an incense stick’s time, but sweat already dampened her temples. She thought to herself, "The lightning in this scorched earth is fierce; if not for cultivating the transformation technique, it would be hard to even approach."

The latter part of the task was more challenging: capturing a "Tribulation Ash Resentful Spirit." These spirits were remnants of souls failing tribulations, floating deep within the ancient forest, their forms as ethereal as smoke yet bearing strong resentment and lightning attributes, adept at ambushing the heart and mind.

Following her Divine Sense, Si Lingle ventured deeper into the forest’s core. The fog grew thicker here, visibility only ten steps, the air filled with a howling wind mixed with whispers of the dead: "Why didn’t you save us... we’ll be destroyed together..."

The whispers of resentful spirits corrode the Dao Heart, Si Lingle silently recited the Clear Heart Technique, resisting mental agitation. She had faced Heart Demons head-on during assessments at the Thunder Extreme Immortal Sect, making such illusions minorly impactful on her.

Next to an abandoned altar, Si Lingle finally encountered her target: a Tribulation Ash Resentful Spirit condensed into form.

It appeared as a humanoid shadow, surrounded by blue-black electric arcs, its hollow eye sockets flashing red light, devouring surrounding lightning fragments.

The resentful spirit screeched once it saw her, swooping towards her with a wave of bone-chilling resentment shock.

Si Lingle advanced instead of retreating, accelerating the flow of immortal power through her technique, sealing with both hands to summon nine wooden spikes — a skill from the Magic World, now refined into the immortal technique "Ten Thousand Forest Formation." The wooden spikes shot out, weaving into a net trapping the resentful spirit.

The resentful spirit struggled and roared, unleashing lightning strikes, but the wooden net absorbed the electric force, becoming even sturdier.

Seeing itself at a disadvantage, the resentful spirit suddenly split into three strands, attempting to flee.
