The light shattered behind them. Darkness slammed down, absolute and suffocating. An oppressive

  weight settled into the marrow of his bones, the weight of the world pressing in from all sides. He

  was underground, trapped in a throat woven from the gnarled roots of dead gods. A sickly green

  glow pulsed from the wood, a phantom heartbeat in the gloom, throwing shadows that clawed at

  the edges of his vision.

  The air was a thick, wet poison. Each breath was a struggle, dragging the taste of grave-dirt and

  decay deep into his lungs.

  Krupp’s claws dug into the fabric of his cloak, a frantic, needle-sharp pressure against his shoulder.

  A low vibration, a constant whimper, shuddered through him from the bird’s puffed-out form. Four

  terrified eyes burned in the dark, scanning the encroaching rot.

  Deeper. The pressure mounted, a stone shroud laid upon his soul. The green pulse of the roots bled

  into a grayish-brown twilight that devoured light. The air thickened to sap. His lungs burned.

  “These spores…” Jin Luo’s voice was a strained rasp. The red line on his detector was a flickering

  wound in the dark. “Neurotoxins. Hallucinogens. They’ll give your fear teeth.”

  My fear already has teeth.

  He saw it in the others. Huang Xiaohu’s golden wings were leaden, dragged down by invisible

  chains of stone. The fire in him guttered, choked by the damp wood. Alanka’s face was ash, the

  Earth power draining from her like sand from a cracked hourglass. The decaying passage was a

  parasite, and she was its host.

  Then came the whispers. They slithered from the wood, but they bloomed inside his skull. Luo Han

  flinched, hearing phantom cries. Laughter, sharp and cruel as glass, made Huang Xiaohu bare his

  teeth. For him, it was the voice from the Sun God’s temple, an echoing curse that coiled around his

  heart. “The great reincarnation… has opened the gates for us…”

  Ya Mei’s fingers tightened on her jade flute, a silent anchor in the storm of whispers. The presence

  of Shuifulin, a deep and quiet water, slept within her, undisturbed.

  Hours bled into one another. Nerves stretched taut as bowstrings, ready to snap.

  The path fractured. Two tunnels yawned before them. The left, wide and flat, bled a demonic energy

  so dense it was a physical chill on his skin. The right was a narrow, treacherous maw of crumbling

  roots, but the spiritual energy within felt… clean. Alive.

  Jin Luo’s detector shrieked, a sound of pure panic. “Left path suppresses non-Wood power.

  Seventy percent suppression.”

  “And the right?” His own voice sounded hollow.

  Alanka swayed, her voice a fragile whisper. “The right… it’s a detour… but I can breathe.” The

  Root Path was already drinking her power. The left path would leave her a husk.

  “We go right,” Luo Han’s voice was granite. His eyes were fixed on Alanka’s pale face.

  “Through that rotten garbage pit? It’s not on the map!” Huang Xiaohu’s wings flared, a burst of

  frustrated fire. “We’re burning time. He say we push through the fast route.”

  “The fast route will cripple her,” Jin Luo countered, his voice tight with irrefutable logic.

  “And a collapse won’t?” Jin Gan’s voice cracked, sharp with a fear that tasted of salt and

  crushing water. “I’m not dying in another tunnel! The left path is stable. It’s known. That’s all

  that matters.”

  Luo Han stepped in front of Alanka, a mountain of flesh and resolve. “We don’t leave her.”

  “Who’s leaving her?” Huang Xiaohu shot back, stung. “What if the right path is a dead end? Or

  it caves in? Then we all die!”

  The air crackled, thick with ozone and rage.

  Krupp pecked frantically at his ear, a tiny, desperate drumbeat. Do something. Fix this.

  “Enough.” The word was quiet, but it cut through the storm.

  They all turned to him. He saw Alanka, a flickering candle. He saw Jin Gan, trembling with the

  memory of drowning. He saw Huang Xiaohu, his pride a burning coal.

  “We go right,” he said, his voice a blade severing the tension. “We don’t leave people behind to

  save a few hours. That’s not who we are.”

  He moved to Jin Gan’s side, laid a hand on the cold, trembling metal of his arm. “I’m scared

  too,” he said, his voice dropping to a low murmur only for him. “We all are. That’s why we stick

  together. A hard path, a long path… we walk it together. If we start tearing at each other down here,

  the whispers have already won.”

  Huang Xiaohu’s golden wings slowly, reluctantly, folded. “…Your lead,” he conceded, the fire in

  his voice banked to embers.

  Jin Gan’s head dropped. The tremor in his mechanical arm stilled.

  Luo Han gave him a single, grateful nod.

  They turned right, into the crumbling unknown. The argument was ash, but the crushing weight of

  the earth remained.

  Another half-day of marching, of breathing dust and decay. Then, the tunnel ripped open into a vast,

  echoing cavern. Krupp launched from his shoulder, a black streak against a sudden expanse. The bird

  circled once, then let out a sharp, clear cry that shattered the silence. All clear.

  Before them, a city of impossible light bloomed in the heart of the earth.

  It wasn’t a city of stone, but of life. Giant, glowing mushrooms formed towers that pulsed with soft

  luminescence. Crystalline rocks veined with light served as walls and bridges. The streets teemed

  with strange, subterranean creatures, their movements unhurried, peaceful. Fluorescent moss

  carpeted the avenues, casting everything in an ethereal glow. The air was a balm, rich with the scent

  of clean earth and fungi, washing the rot from his lungs.

  “Market district ahead,” Jin Luo said, pushing his glasses up. “Restock. Gather information.”

  They stepped into the city’s vibrant heart. Stalls overflowed with bizarre, glowing vegetables,

  writhing vines, and flowers that bled perfume into the air. He reached out, his fingers brushing a

  patch of moss that shone like captured starlight.

  A prickle of ice on his neck. A weight. He was being watched.

  His hand clenched on his Crystal Staff. A low thrum of warning pulsed from the wood, a vibration

  that resonated in his bones. The gaze wasn’t hostile. Just… ancient. And curious.

  Ya Mei touched his arm, her voice a raw rasp. “There…” She pointed a trembling finger at a pile of

  giant cabbages. “A pure aura…”

  He held his breath. Feigning calm, he reached between the leaves. His fingertips brushed something

  small, cool, soft.

  Hey! That tickles! Don’t touch me!

  The voice exploded inside his skull, a shrill thunderclap. He leaped back, sending cabbages tumbling.

  A thumb-sized green creature with three blinking, dewy eyes shot out from the leaves, landing on a

  cabbage head with impossible lightness.

  “A spirit?” he breathed.

  The story has been stolen; if detected on Amazon, report the violation.

  It puffed out its chest. “Vegetable Spirit! And the best-informed one down here!”

  Its middle eye glowed, a piercing light that seemed to strip him bare. “Your spiritual power is…

  strange. The Wood is pure, but inside… are those five different powers?”

  Ice flooded his veins. It knows. How?

  The Vegetable Spirit’s leaves drooped. “Don’t be nervous.” It waved its tiny hands, then hopped

  onto his shoulder, its voice dropping to a conspiratorial whisper. “You carry the scent of the Forest

  Heart… and… that prince’s consciousness…” It glanced at Ya Mei, and its three eyes widened.

  “You’re here for the Forest Heart, aren’t you?”

  The words hung in the air, heavy as stone.

  Xiao Lu suddenly trembled, its eyes darting in terror toward the end of the street. “Oh no! They’re

  here!”

  “Who?”

  “The Black-Armored Guards!” it shrieked. “They tracked you! Run!”

  The uniform tramp of armored boots vibrated up through the soles of his feet. Dozens of guards in

  black plate mail swarmed from the shadows, their runic spears crackling with contained lightning.

  They sealed both ends of the street.

  The captain’s gaze was cold iron. As it swept over them, a dark red light flashed deep in his eyes, a

  spark of banked hellfire.

  “It’s them! Seize them!” he bellowed.

  Xiao Lu dove into the cabbages and vanished.

  “Go!” Luo Han roared. His longsword was a streak of light as he planted himself between them

  and the guards.

  Ke Munan ripped a handful of Voice Transmission Talismans from his pouch, shoving them into their

  hands. The paper felt thin, fragile. “If we’re separated, use these!” He barked a command. “Split

  up! East alley!”

  The world exploded into motion. Huang Xiaohu shot into the air, a golden comet weaving through

  the narrow alleys, drawing a squad of guards after him. Jin Luo and Jin Gan moved as one mind in

  two bodies—one calculating escape vectors, the other firing beams of light from his mechanical arm

  that sent pursuers stumbling. A sharp vibration. Jin Gan yanked his brother sideways an instant

  before a volley of spears shattered the spot where they’d stood.

  Luo Han and Alanka were a storm of fire and earth, a roaring wall that sent guards tumbling like

  broken dolls.

  Ya Mei, running at his side, suddenly stopped. Her hand flew to her temple. “Water…” she gasped,

  sweat beading on her brow. “Shuifulin… is guiding…” She raised a trembling hand. Pointed.

  “…Left…”

  He didn’t hesitate. He veered into the alley. A black maw gaped in the shadows. A sewer entrance.

  “Here!” he hissed.

  One by one, they plunged into the dim, wet darkness. The thunder of armored boots faded above.

  Safe in the dripping silence, Jin Gan collapsed, his breath a ragged saw. “How… how did Bisen

  know?”

  Jin Luo pushed up his glasses, his face a grim mask in the gloom. “He’s been watching us since

  Yellow Lake. He knew.”

  “What now?” Alanka’s voice was a thread of sound.

  He looked at Ya Mei. “Can Shuifulin still guide us?”

  She closed her eyes. A nod. “It says… follow the water… We can bypass the city…” A ragged

  breath. “…Straight to… Tearlight Swamp…”

  He tapped his staff three times on the stone floor. A sharp, final sound. “Let’s go. Bisen knows our

  goal. We can’t afford to be slow.”

  They moved on, deeper into the darkness. The city died behind them. Ahead lay only the unknown.

  They clawed their way out of the sewer into a world of nightmare. The stench hit first, a physical

  blow of rot and sorrow. The forest was a graveyard. Trees were skeletal claws reaching for a sky that

  wasn’t there, their bark weeping a thick, black sap that smelled of death. A palpable grief hung in

  the air, a cold weight that settled in his chest. The wind itself was a sob.

  “The life energy…” Ya Mei whispered, her hand hovering over a withered trunk. “It’s being

  drained.”

  “Dark power,” he said, his knuckles white on his Crystal Staff. He could feel it now, a black heart

  pulsing deep in the earth, a greedy, devouring thing.

  A roar tore through the trees.

  Shadows erupted from the gloom. Deer, wolves, a bear. Their eyes burned with a feral, dark red light.

  Black patterns scarred their bodies. They charged, a tide of corrupted flesh and mindless rage.

  “They’ve been corrupted!” Alanka cried.

  It was a battle that tore at the soul. Ya Mei raised her flute, a melody of peace against a storm of

  pain. The song that could calm a hundred beasts now only drew agonized howls.

  “Don’t kill them!” he shouted, his voice raw. “Drive them back!”

  They fought to repel, not to wound. Luo Han’s flames became a cage, not a pyre. Jin Gan’s pellets

  stunned, they did not maim. Huang Xiaohu became a golden lure, drawing the herd away.

  They broke through, bleeding from a dozen minor wounds that stung less than the memory of those

  red eyes.

  “He doesn’t even spare the animals,” Luo Han’s voice was cold fury.

  Another half-day. They broke through the skeletal trees into an open expanse of water—Tearlight

  Swamp.

  It was a place of impossible, tragic beauty. The water was a mirror that reflected no sky, only a void.

  Countless motes of soft light drifted on its surface, the shed tears of souls. In the center, an altar of

  intertwined dead roots stood in silent vigil.

  Ya Mei froze. Her body convulsed, her hands pressed to her brow. When she spoke, the voice was

  not her own. It was Shuifulin’s, weak but clear as water.

  “It is there… The Forest Heart… on the altar…”

  He felt it too. A pulse of pure life radiating from the altar, a thrum that resonated with the Sun

  God’s power buried deep in his own core.

  “Let’s go,” he said. “We’re taking it back.”

  They stepped onto a stone path hidden just beneath the water’s surface, moving toward the altar.

  A hundred paces out, a voice filled the swamp. It came from everywhere and nowhere, a mocking

  stage whisper that coiled around them like a snake.

  “Welcome to my hunting ground.”

  From the shadows behind the altar, a figure emerged.

  King Bisen stepped into the light. His royal robes were magnificent, his posture flawless. But he was

  wrong. A deep, fundamental wrongness clung to him like a shroud.

  His movements were too fluid, a puppet’s perfect grace. His smile was a flawless curve that held no

  warmth, no life. And deep in his eyes, a strange, dark red light pulsed like a dying coal.

  “I’m surprised you found this place,” he said, clapping slowly. The sound was hollow, dead. It was

  the playful cruelty of a cat with a broken-winged bird.

  At his applause, the swamp churned. Dozens of elite guards in black armor rose from the mire, runic

  spears leveled, surrounding the altar.

  “It was you,” Ke Munan snarled, the words torn from him. “You poisoned this forest!”

  “Poisoned?” Bisen laughed, a theatrical, empty sound. “No. He liberated it.”

  He raised his hands. Demonic energy poured from his palms, condensing into shrieking blades of

  pitch-black night that screamed toward them.

  “Fight!” Ke Munan’s staff struck the stone path three times. The command was a crack of

  thunder.

  Luo Han became a living volcano, roaring as he charged. The black blades shattered against his aura

  of fire. Alanka threw up a shield of granite. Huang Xiaohu was a golden comet, carving arcs of death

  through the guards.

  But the thing on the altar was too powerful.

  A blade of shadow caught Huang Xiaohu’s right wing. Golden blood sprayed across the black

  water. Cracks spiderwebbed across Luo Han’s defenses.

  “Give up,” Bisen said, his voice dripping with amusement. “Your struggle is so very entertaining.”

  Ke Munan gripped his staff, watching his friends being torn apart.

  Just then, a figure of woven moonlight drifted from the trees. Prince Bilin. His soul-form was more

  transparent now, a ghost of green light sustained only by the forest’s dying will.

  “Bisen…” The name was fifteen years of suppressed rage. “Usurper!” His form trembled. “You

  stole the Forest Heart. You imprisoned him. Did you think this day would never come?”

  Bilin faltered. He stared at the face identical to his own. He saw the perfect smile. The fluid turn of

  the head. He felt… nothing. The life aura of their bloodline, the very essence of the forest, was gone.

  In its place was a cold, nauseating void.

  “No…” Bilin’s voice trembled. A flicker of profound confusion crossed his spectral face. “You’re

  not… you’re not Bisen.”

  He recoiled, his soul-form shimmering violently. “My brother… even in his betrayal, he carried the

  life of the forest. But you…” A tear of pure light traced a path down his cheek as the horrifying truth

  crashed down on him. “There is nothing of the forest in you. Only rot. Only death.”

  His voice shattered with grief, then hardened into a blade of fury. “My brother is dead, isn’t he?”

  he whispered, before roaring, “And you are just the thing wearing his skin!”

  The swamp fell into a deathly silence.

  The perfect smile on “Bisen’s” face finally cracked. His eyes turned into abyssal pools of crimson.

  “Ha… hahaha…” A low laugh escaped his lips, a chilling duet of two voices—Bisen’s, and a cold,

  ancient hiss. “You found me out? As expected of my… ‘dear brother’.”

  His form distorted. Black demonic energy surged from his body, coalescing behind him into a

  monstrous, shadowy horror.

  “That’s right,” the dual voice said. “Bisen died long ago. This excellent vessel belongs to him.” A

  cruel smile played on his lips. “I never liked the name ‘Bisen’. Too weak. Too human.”

  He lifted his head, crimson eyes flashing with arrogance. “I much prefer my real name—Bulaiwei. A

  name for a conqueror!”

  The revelation hit like a physical blow. The king was a demon.

  “You think this is the end?” Bulaiwei sneered. “Our pawns… are not limited to one king.”

  “Lies!” A nova of green light erupted from Bilin’s soul. “These young people are the hope of the

  forest,” he cried, his gaze falling on them. “You will not shake their faith!”

  He raised his hands. A brilliant green beam—the last of his soul’s connection to the Forest

  Heart—shot from his chest toward the altar. The darkened Heart vibrated, then pulsed with a

  blinding light in response.

  “Stop him!” Bulaiwei shrieked.

  Too late. The two streams of light merged. A wave of pure life swept across the swamp. The tear-like

  motes danced. New shoots erupted from dead roots. The Black-Armored Guards were thrown back

  like toys.

  The complete Forest Heart rotated slowly in the air, a radiant emerald sun.

  Bilin’s soul-form jolted. He looked at Ya Mei.

  “I promised you…” his weak voice carried the weight of an oath, “that I would use the Forest

  Heart… to heal her.”

  The Heart shot toward Ya Mei, enveloping her in a waterfall of emerald light. It was life itself, warm

  and vast as the sea. Her body floated into the air. He watched as the light stitched the torn

  fragments of her soul back together.

  She closed her eyes, tears of release streaming down her face.

  When the light receded, she landed softly. She opened her mouth.

  “I…” Her voice was hoarse, but whole. “Thank you… Prince Bilin…”

  Bilin smiled. “This is what… I owed you…”

  The Forest Heart descended, hovering before Ke Munan. It was no longer a gem, but a warm,

  pulsating sphere of emerald light.

  “Take it…” Bilin’s form grew transparent, dissolving into motes of light. “The Sun God’s

  power… resonates with it… That is why it chose you… Use it… to save… my people…”

  His soul was almost gone, a faint sigh on the wind. “Brother… I’m sorry… I couldn’t… find out

  sooner…” His form drifted away like smoke, back to his prison.

  Bulaiwei stood frozen. The crimson light in his eyes flickered. His body trembled, a twisted

  expression of pain marring his perfect face.

  “Brother…” A faint voice was squeezed from deep within his throat, the last ghost of Bisen’s

  consciousness. “Bro… ther… I…”

  The crimson light flared, consuming him. The demon was back in control, its face a mask of cold,

  cruel victory.

  The Forest Heart settled into his hands. It was not a jewel. It was a storm. A raging river of life force

  coursed through him, a power so immense he could not command it. He was a child holding a

  greatsword, its sheer weight dragging him down. It’s too much. It’s going to tear me apart.

  Bulaiwei stared, a flicker of apprehension in his eyes quickly smothered by a cruel smile.

  “Let’s see…” He held out a hand, black energy gathering. “How long the new host can last.”

  A blade of pure void shot toward him—

  The Forest Heart erupted.

  A transparent emerald shield flared into existence, and Bulaiwei’s attack shattered against it

  harmlessly.

  “Oh?” Bulaiwei retracted his hand. “It has already accepted you.”

  He attacked again, a tide of pitch-black energy surging forward. The shield didn’t move. It began to

  absorb the darkness, converting it to pure life.

  “Killing you directly won’t work,” Bulaiwei said, his expression chillingly calm. “If I destroy you

  both… I get nothing.” A cruel arc formed on his lips. “However… I anticipated this.”

  He untied a black talisman pouch from his waist.

  “What if you were to die a slow, non-violent, natural death?” he mused, pulling out a

  transportation talisman that flickered with an eerie red light.

  “Hahaha!” With a piercing laugh, he held it high. “The corrosion of the Poison Sea will strip your

  life away. Once you die, the Forest Heart will detach itself and return to him!”

  He crushed the talisman. “You want the Forest Heart? Then take it with you and rot in the Poison

  Sea!”

  The ground shattered. A massive black transportation formation erupted beneath their feet,

  radiating an aura of pure chaos.

  “Transportation formation!” Jin Luo screamed in horror. “The target is… the center of the Poison

  Sea!”

  He tried to move, but the Forest Heart was a mountain, pinning his soul in place.

  “Hold on to each other!” he roared.

  Hands gripped his. A desperate chain against the storm. Krupp shrieked, pressing against his chest.

  “Enjoy the ‘surprise’ I’ve prepared!” Bulaiwei’s laughter echoed as the world tore apart. “A

  death zone even the Ship Nation avoids! I’ve even left a little gift for you…”

  Space twisted. His ears filled with his friends’ cries.

  His vision cleared. The stench hit him first—a pungent, rotten assault that choked him.

  They were trapped. A transparent, spherical barrier, floating on a grayish-green sea. Strange runes

  burned across its surface, emitting a crushing magnetic field.

  “A Magnetic Seal Sphere!” Jin Luo’s voice trembled. “He planned everything!”

  Around them, the endless Poison Sea. Black water exhaled a nauseating gas. Mutated sea monsters

  poked hideous heads from the depths, their eyes fixed on the new prey.

  Worse. The sphere was sinking.

  “We have to break this!” He tried to command the Forest Heart, but its power raged,

  uncontrollable and wild. They were falling, plummeting into the abyss beneath the roots.

  Here is the rewritten Part 1 of the chapter, following the Unified Style Guide.
