The journey of the nameless sapling takes a dramatic turn when a withered golden leaf lands on her branches, triggering a massive storm of energy that unlocks her hidden heritage. She evolves into a World Tree, gaining the name Tianlian Liu Shu, along with extraordinary stats that defy her low level. Her peaceful existence is quickly shattered when a hostile Level seven Thornstride predator named Fraar, lured by her highly nutritious scent, attacks her trunk to devour her. Believing the young tree is easy prey, the beast leaps forward, but Liu Shu unleashes her newly gained Willow Strike talent, whipping the creature with fearsome precision and strength. The predator is completely shocked as its tough skin is easily sliced open by her metallic branches, and the battle escalates into a brutal barrage of strikes. Liu Shu creates a new skill called Willow Strike Barrage, delivering a relentless rain of attacks that shatters the beast's skull and reduces its vitality to zero. This shocking reversal leaves the surrounding wildlife in awe and marks her first step toward becoming an absolute overlord of the forest. The system rewards her with experience points, and she realizes that the path of survival in this world requires absolute ruthlessness against those who treat her as prey. She begins to actively cultivate her abilities, realizing that her high stats allow her to fight creatures far above her level. As she adapts to her new reality, her mind sharpens, and she starts to attract a variety of small animals and insects, fostering a harmonious ecosystem around her trunk. Yet, her rapid growth and the sweet scent of her sap continue to leak into the wider forest, acting as a beacon for even more dangerous entities that lurk in the deep shadows, waiting for the perfect moment to strike her down. She stands proud, her roots digging deeper into the earth, ready to face whatever challenges the cosmos throws at her, unaware that her awakening has already set off a chain reaction that will draw both friends and foes to her grove.

Her unique aura attracts Clavel, a Rose Fairy who is amazed by Liu Shu's extraordinary stats and delicious berries. Recognizing her immense value, Clavel brings her leader, Flor, to inspect the young tree. Flor, a Level ten powerhouse, instantly recognizes Liu Shu's potential and uses her pollination skill to help her level up. In doing so, Flor triggers a system reward that upgrades her own lineage, transforming her into the Rose Fairy Queen and boosting her strength to Level twelve. The fairies decide to make Liu Shu their forever home, establishing a defensive perimeter and building a secret underground vault to store their treasures. This alliance creates a mutually beneficial ecosystem where the fairies groom and protect Liu Shu, while she provides them with magical berries that boost their experience and recovery. As Liu Shu assimilates the vault with her roots, she unlocks city planning functions and gains an inventory, further solidifying her control over her domain. The surrounding forest begins to change as her roots spread, and the fairies work tirelessly to nourish the soil. This sudden concentration of power does not go unnoticed by the other forest factions, who begin to view the growing alliance as a threat to their survival, setting the stage for an inevitable clash of civilizations.

The tension in the forest reaches a boiling point when the Thornstride leader, Froorar, rallies a massive coalition of beasts to eliminate the threat of the Rose Fairies and the mysterious tree. Hundreds of creatures, including Level ten and eleven powerhouses, march toward the grove. At the same time, a talented Sylvan named Cinderielle arrives, drawn by her childhood connection to the golden leaf. As the battle commences, Liu Shu unleashes her full might, using her extended Willow Strike and Root Manipulation to slaughter the invading beasts and turn them into fertilizer. Cinderielle transforms into her powerful Sylvan form, unleashing devastating fire magic that incinerates the Level eleven magpie and Froorar in a spectacular display of power. Flor and the remaining fairies fight alongside them, successfully repelling the massive invasion. The bloody victory establishes Liu Shu's absolute dominance in the Golden Sap Forest, but the cost is high, with many fairies and ants falling in battle. The surviving humans and Cinderielle agree to form a permanent alliance, promising to help build a town around the World Tree, ensuring that the grove remains protected against future threats from the surrounding human cities.

Following the devastating war, Liu Shu focuses on rebuilding her damaged root system and expanding her knowledge. Having absorbed several books on architecture and woodworking brought by her allies, she gains a deep understanding of construction. She decides to build her first defensive structure, the Lignified Mother of Thousand Flower Field, using her own World Tree branch as a substitute for rare materials. The structure is a beautiful ring of tubular flowers that can shoot explosive seeds with high precision, successfully defending her grove from aerial predators. As her level approaches five, she prepares to unlock even greater powers, while her human and Sylvan allies work to establish a thriving town around her. This marks the transition from a solitary sapling into the heart of a rising civilization, setting her on a path of rapid expansion that will eventually challenge the ancient powers of the Sylvan Cosmos.
