Chapter 1: The Mist Forest's "Light-Devouring Vine" Trap

The air in the Spirit Plant Realm carried the damp, fresh scent of vegetation. The moss beneath their feet was as soft as velvet, and the crowns of towering ancient trees intertwined to form a green dome, allowing sunlight to scatter through the gaps in tiny specks. But in this seemingly tranquil forest, every inch of vegetation could conceal deadly danger. Just half an hour after they entered, purple roots suddenly shot out of the ground and wrapped around the soles of Xiao Yan's boots. The barbs on the roots pierced the leather, sending waves of numbness through him.

"These are juvenile 'Light-Devouring Vines,'" Lu Mu said, severing the roots with a specially made dagger whose blade was coated in a transparent "anti-paralytic agent." "They lie hidden under decaying leaves during the day and bloom with fluorescent flowers at night. Once a creature passes by, their roots latch onto their prey like leeches, and the sap they secrete can stiffen a person's muscles." He pulled a copper compass from his backpack. Its face was engraved with all kinds of plant designs, and its needle was trembling wildly as it pointed northwest. "The compass shows that the World Tree Sapling is in Emerald Valley to the northwest, but there are at least three high-level spirit plant traps along the way."

Zi Yan suddenly tugged at Xiao Yan's sleeve, her dragon eyes fixed warily on the bushes ahead. "Something's moving over there. It's not an animal, it's... the sound of a plant's heartbeat." No sooner had she spoken than the bushes burst apart. Dozens of green vines as thick as bowls shot out like pythons. Silver scales covered their surfaces, and the buds at their tips popped open, revealing rings of sharp teeth. They were mature Light-Devouring Vines!

[System notification: Encountered "Light-Devouring Vine Cluster" (level: Dou Wang). Characteristics: vines can rotate and coil 360 degrees; sharp teeth secrete paralyzing venom. Weakness: the golden pistil at the center of the bud at the tip.]

"Xiao Yan, use fire!" Zi Yan spread her wings, and Dragon Phoenix Flame turned into a fiery tornado, setting the vines lunging toward them sizzling. The vines rapidly shrank back from the fire, only to send new branches shooting out from their roots. Xiao Yan immediately unleashed his Heavenly Flames, and the Elemental Core's Fire Attribute light merged into them. The orange-red flames instantly turned pure white-flames fused with "life energy," the bane of spirit plants' regenerative ability.

Crackle! The pure white flames licked over the vines. The burned sections no longer put out new shoots, instead charring black. Wu Hao raised his alloy shield and charged into the densest patch of vines. Runes lit up on its face, shaking off the vines that wrapped around it. "Lu Mu, find their main root! A cluster plant like this has to have a mother vine!"

Lu Mu's compass suddenly pointed toward a giant tree ahead and to the left. A thick layer of moss covered its trunk, and writhing roots were faintly visible beneath it. "Inside that Ironbark Tree! The mother vine is parasitizing its heart!" Lin Xiuya's sword flashed, and he became an afterimage as he charged toward the giant tree. The instant his longsword pierced the trunk, vines throughout the forest shuddered violently. Sure enough, the mother vine's nerves were connected to all its offspring!

"Now!" Xiao Yan tossed the Elemental Core into the air. It released five-colored light, and the Wood Attribute light turned into countless threads that bound the branches of every Light-Devouring Vine. "Zi Yan, aim for the heart of the tree!" Dragon Phoenix Flame condensed into a flaming spear and shot toward the trunk with a whoosh. The spear pierced the bark, and a muffled explosion sounded from the heart of the tree. Every Light-Devouring Vine instantly lost its strength and drooped limply to the ground, the buds at their tips withering one after another.

After clearing away the vines, Lu Mu retrieved a golden seed the size of a mung bean from the mother vine's remains. "This is the Light-Devouring Vine's Reverse Growth Seed. Bury it in the soil, and it'll grow moss that purifies toxins-just the thing to deal with the Root Rot Disease ahead."

Chapter 2: The Swamp's "Heart-Rot Lotus" and the Antidote

After they passed through the Mist Forest, a dark-green swamp appeared ahead. Layers upon layers of lotus leaves floated on its muddy surface, and the flowers at their centers were an eerie purplish black. Thick liquid dripped from the edges of their petals, bubbling when it fell into the mud. These were Heart-Rot Lotuses, capable of secreting an extremely corrosive sap. Worse still, countless white "rotten roots" lay hidden beneath the mud. Anyone who touched them would be dragged under and become nourishment for the lotuses.

[System notification: Entered the "Heart-Rot Lotus Swamp," one of the sources of Root Rot Disease. Quest branch: gather "Clear Heart Grass" to make an antidote, or contact with Heart-Rot Lotus sap will cause continuous health loss.]

"Clear Heart Grass grows on the Stone Island in the middle of the mire," Lu Mu said, pointing to a small patch of land at the swamp's center. A clump of silver-green grass grew on the island, dewdrops rolling over its leaves. "But the rotten roots in the mud actively attack moving objects. Their sense of touch is even keener than a snake's."

Hu Gan crouched down and dipped the Black Tortoise Shield into the mire. Countless tiny white roots immediately clung to its surface, then rapidly rotted away when they touched the runes on the shield. "My shield can purify toxins. Perhaps it can open a path." He laid the shield flat on the mud, and sure enough, the roots curled up and retreated whenever they touched it.

"I'll be the bridge pier!" Wu Hao shouldered his alloy shield and jumped into the mire. Dark-brown mud rose past his knees as he planted the shield at an angle, forming a triangular support. "Xiao Yan, carry Lu Mu across to gather the grass. Hu Gan and I will take turns switching shields!"

Carrying Lu Mu on his back, Xiao Yan stepped onto Wu Hao's shield and leaped toward another shield supported by Hu Gan. The rotten roots beneath the mud sensed the movement and surged toward them like a swarm of white snakes, only to be blocked by the shields. Just as Lu Mu reached for the Clear Heart Grass, the Heart-Rot Lotuses in the middle of the swamp suddenly turned toward them in unison. Their petals opened, and purplish-black sap came pouring down like a rainstorm!

"Watch out!" Xiao Yan immediately used the Elemental Core to raise a barrier. The sap struck it and turned into green smoke. "Zi Yan, burn their calyxes!" Dragon Phoenix Flame swept across the water, setting the Heart-Rot Lotus petals alight, but as they burned, they released an even denser poisonous mist.

"Quick, pick the grass!" Lu Mu lunged onto the Stone Island and pulled up the Clear Heart Grass by its roots. Dewdrops fell from its leaves into the mire and actually dissolved the surrounding rotten roots into foam. "So Clear Heart Grass sap is a natural antidote!" He crushed the leaves and smeared the sap on everyone's cuffs and boot soles. Sure enough, the rotten roots all swerved away when they touched it.

Back on the bank, Lu Mu used the Clear Heart Grass and the Reverse Growth Seed they had obtained earlier to prepare a pale-green antidote. "This can temporarily resist the erosion of Root Rot Disease, but to get rid of it completely, we'll still need the World Tree Sapling's Dew of Life."

Chapter 3: Emerald Valley's "Forest Guardians" and the Symbiosis Trial

Emerald Valley was enclosed by a ring of sheer cliffs. On a stone platform in the center of the valley, a sapling half a meter tall was trembling. Its leaves were yellowed and curled, and black rotten roots were wrapped around its base. It was the World Tree Sapling. Around the platform stood six "Forest Guardians" made of vines and bark. They were tall, with masks formed from hollows in trees, and carried spears woven from branches.

[System notification: Encountered "Spirit Plant Realm Forest Guardians" (level: Dou Emperor). Not enemies. The "Symbiosis Trial" must be passed to gain permission to awaken the sapling. Trial objective: demonstrate affinity with nature. Three people must work together to complete the "Life Cycle Formation".]

A tree hollow on the mask of the leading Forest Guardian opened, and an aged voice emerged. "Outsiders, the World Tree is the heart of the Spirit Plant Realm. If you cannot prove that you can protect it, then please leave." It pointed to three recesses in the stone platform. "Pour your purest energy into the recesses and form a cycle, proving that you and nature share the same origin."

Xiao Yan, Zi Yan, and Lu Mu exchanged glances and stepped forward. Xiao Yan set the Elemental Core into the middle recess, and it released five-colored energy. Zi Yan cut her fingertip and let dragon blood drip into a recess, sending red dragon power spreading along it. Lu Mu mixed Clear Heart Grass sap with the Reverse Growth Seed and poured them into the final recess, and green life energy burst forth from the soil.

The three energies flowed through the recesses, but repelled one another when they met. Xiao Yan's elemental power was too domineering, Zi Yan's dragon power was aggressive, and Lu Mu's life energy was too gentle. Patterns of disappointment appeared on the Forest Guardian's mask. "The energies conflict and cannot circulate. The trial has failed."

"Wait!" Xiao Yan suddenly remembered the principles of cooperation he had learned in Mechanical City. "We have to make the energies complement one another! Zi Yan, wrap your dragon power around the life energy so it won't be scorched by my Fire Attribute. Lu Mu, guide the life energy into the gaps in the Elemental Core to act as a lubricant. I'll harmonize the Fire and Wood Attributes!"

On their second attempt, Zi Yan's dragon power became a thin red film that gently wrapped around the green life energy. Lu Mu controlled the threads of energy, winding them around the Elemental Core like vines. Xiao Yan suppressed the Fire Attribute until it was merely warm, and wove it together with the Wood Attribute life energy into an orange-and-green band of light. This time, the three energies formed a perfect closed loop in the recesses. Emerald-green shoots sprouted from the stone platform, and the black rotten roots wrapped around the sapling began to loosen.

The Forest Guardians sighed with relief and planted their spears in the ground. The spears became a ring of green light, sealing the stone platform off from the outside. "Go on. Use your energy to awaken it, and the World Tree will grant you a gift."

Chapter 4: The World Tree Awakens and Root Rot Disease Ends

Xiao Yan pressed the Elemental Core against the World Tree Sapling's roots, Zi Yan's dragon blood dripped onto its yellowed leaves, and Lu Mu's life energy seeped through the soil into every root. The sapling trembled as it unfurled its leaves. Under the impact of the three-colored energy, the black rotten roots gave way segment by segment, turning into black powder. Suddenly, a new leaf grew from the top of the sapling, and a crystalline dewdrop formed on it-the Dew of Life.

The instant the dewdrop fell, all of Emerald Valley began to shake. Waterfalls appeared on the cliffs, dead trees sent out new shoots, and the Heart-Rot Lotuses in the swamp turned into pure white water lilies. Even the taint of Root Rot Disease in the air was replaced by a fresh fragrance. The Forest Guardians knelt on one knee and saluted the World Tree. "Thank you, outsiders. The Spirit Plant Realm will always open its doors to you."

[System notification: Main quest complete! The World Tree Sapling has awakened, and Root Rot Disease has been eliminated. The team has unlocked the "Spirit Plant Communication" talent (allows simple communication with plants) and obtained "Dew of Life x3" (instantly heals severe injuries).]

Xiao Yan picked a new leaf from the World Tree, and it turned into a green mark in his palm. "Is this... the World Tree's contract mark?" The Forest Guardian explained, "It allows you to sense plants' emotions on any plane. You may consider it proof of symbiosis."

Zi Yan suddenly pointed outside the valley. "Look! Those Light-Devouring Vines are waving at us!" Sure enough, the vines at the edge of the forest were swaying gently, and the buds at their tips had opened into harmless little white flowers. On Lu Mu's compass, the red dots representing danger had all turned into green smiling faces.

[System notification: Team status fully restored. "Life Energy Affinity" passive activated. Next plane coordinates generated: "Crystal Core Star". Teleportation countdown: 1 hour.]

Xiao Yan tucked the Elemental Core inside his robes. A green pattern had appeared on its surface-the mark of the Spirit Plant Realm. He gazed at the World Tree Sapling flourishing in the distance and suddenly understood that whether it was the steel of Mechanical City or the vegetation of the Spirit Plant Realm, life was connected at its core: it needed protection, it needed cooperation, and above all, it needed the courage to always strive to make everything better.
