Then a sharp glimmer cut across his vision.
[World Tree Evolution Initiated]
[Estimated Duration: 2-5 minutes]
[Warning: Mana density will increase significantly during evolution]
He froze. The words hovered where only he could see, pulsing with an urgency that made his chest tighten. Before he could process the full weight of what was coming, he turned to his companions.
"It's about to evolve," Ciel said, his voice cutting through the growing tension. "The World Tree—the system says it's evolving. This is going to take a few minutes, and the mana density is going to spike."
Sora's eyes widened. "Evolve? Into what?"
"I don't know," Ciel admitted, watching the countdown timer appear in his peripheral vision.
[Time Remaining: 04:47]
Before anyone could respond further, the tree surged.
The sound was unlike anything they'd heard—a deep, resonant crack that seemed to split reality itself. Bark fractured like stone under immense pressure, revealing glimpses of something luminous beneath. The roots beneath their feet writhed and coiled deeper into the soil, sending tremors through the ground that forced all three to brace themselves.
Veldora lifted his shield instinctively, his warrior's reflexes responding to the raw power emanating from the tree. "Should we move back?"
"I don't think it matters," Ciel replied, transfixed as the trunk began to stretch upward in defiance of natural law. The growth wasn't gradual—it was explosive, violent in its intensity. Wood creaked and groaned as the tree doubled in height within the first minute, bark reforming over the glowing core beneath.
The air itself grew thick, saturated with mana so dense it felt like breathing liquid light. Sora gasped, pressing a hand to her chest. "It's heavy—the mana. I can barely breathe."
[Time Remaining: 02:33]
New branches burst forth from the expanding trunk, unfurling like the arms of a awakening giant. Each leaf that sprouted shimmered with an inner radiance, drinking in the ambient light and somehow magnifying it. The canopy spread wider, casting dancing shadows that seemed to move with purpose.
Ciel watched, mesmerized, as veins of light pulsed through the bark, creating intricate patterns that reminded him of circuit boards or neural networks. The tree wasn't just growing—it was becoming something more complex, more aware.
[Time Remaining: 00:45]
The final moments of the evolution were the most intense. The tree's trunk solidified at nearly two meters tall, its branches reaching toward the sky with an almost reverent grace. The leaves settled into a gentle rhythm, their glow stabilizing into a warm, welcoming light that seemed to chase away the stark artificial feel of the empty realm.
Then, silence.
The transformation was complete, and the oppressive weight of evolving mana began to settle into something more manageable—though still notably denser than before.
[World Tree Evolution Complete]
[Current Stage: Sapling]
More text cascaded across Ciel's vision, and he took a moment to absorb the information before sharing it.
If you stumble upon this narrative on Amazon, it's taken without the author's consent. Report it.
"It's done," he said, his voice carrying a mix of awe and apprehension. "The system calls it a Sapling now."
"Sapling?" Sora stepped closer, studying the transformed tree. "It's twice the size it was before. If this is a sapling, what's it going to become?"
Before Ciel could answer, more information flooded his interface:
– WP Generation: +100 WP/day (↑ from +25 WP/day)
– Time to Next Stage: 1 year (365 days)
– Mana Maintenance Cost: 200 mana/day (↑ from 50 mana/day)
– Effect: Amplifies mana concentration within the Realm
– Mana Density: Medium-Low → High-Low
"The good news is it's generating four times more World Power now," Ciel explained, reading through the statistics. "The concerning news is it's also consuming four times more mana daily just to maintain itself. That means I need to build more mana wells if we want to keep mana for ourselves"
Veldora lowered his shield but kept it ready. "And the air feels like it's charged with lightning. Is that normal?"
"The mana density increased. The tree is amplifying the concentration of mana in the realm." Ciel paused, feeling the weight of responsibility settling on his shoulders like a mantle. "We're not just maintaining a plant anymore. This thing is actively reshaping our environment."
The revelation hung heavy between them until another window appeared, this one making Ciel's stomach clench with its implications.
[New Passive Available for Unlock]
– Ecosystem (Passive): The World Tree begins the genesis of life. By enriching barren land into fertile soil, spawning microorganisms, and establishing natural cycles, it lays the groundwork for a thriving biosphere. Once unlocked, the Realm will begin nurturing self-sustaining lifeforms.
Unlock Requirements: – 10,000 Units of Biomass (from monsters as their level increases so does their value):
- 1 kg of Lv. 1–4 monster = 1 unit
- 1 kg of Lv. 5–9 monster = 2 units
- 1 kg of Lv. 10–19 monster = 4 units
- 1 kg of Lv. 20–29 monster = 8 units
– 1 Dungeon Core: Functions as the blueprint of the ecosystem the tree will create. The dungeon's nature determines the initial environment created (e.g., forest, volcanic, aquatic).
[Warning: Failure to meet conditions within 6 months will result in the World Tree entering a 3-month dormancy seal leading to 0 world power production.]
Ciel's breath hitched. The scope of what the tree was offering—demanding—was staggering.
"There's more," he said, his voice heavier now. "The tree can create life here. An entire ecosystem. But it needs resources."
Sora turned from her examination of the new branches. "What kind of resources?"
"Biomass. From monsters. Ten thousand units’ worth, calculated by weight and level." He let the impossibility of the number settle. "And a Dungeon Core."
The silence that followed was punctuated only by the soft whisper of the tree's new leaves, their gentle luminescence casting shifting patterns across their faces.
Veldora was the first to speak. "Ten thousand units. That's... a lot of dead monsters."
"It's not just about killing them," Ciel clarified, though the distinction felt hollow. "We'd need to harvest them properly. The system tracks biomass by weight and monster level."
“And Dungeon Cores,” Sora muttered, running a hand through her hair. “Those aren’t just rare—they’re practically priceless. They are gained when you first clear a naturally spawning dungeon giving you the access to dungeon making you the owner. Natural dungeon clears are controlled by guilds. Even if you want to buy from the market, you’re looking at six figures in mana stones, minimum.” Her voice cracked, frustration bleeding through. “How are we supposed to get one of those?” Silence pressed in on them. The tree loomed overhead, no longer a fragile sapling but a sentinel of light and promise, its leaves swaying as though whispering secrets they weren’t ready to hear.
Ciel let the quiet stretch before speaking. “It’s not impossible. Just… beyond us right now.” He tore his eyes from the glowing bark and looked at his friends. “But this is proof. The Realm can grow. It can become more than a training ground—it can become alive. If we meet the conditions well, we have six months to do it therefore let’s first work on what we can for now getting the ten thousand units of biomass we were going to dungeons anyway we now have another motivation now.”
The three of them stood beneath the transformed tree, its presence now feeling less like a gentle companion and more like a silent judge weighing their worthiness. Where once it had been a simple sapling representing hope and potential, it had evolved into something that demanded action, sacrifice, and commitment.
Yet beneath the mounting pressure and impossible requirements, Ciel felt something else stirring—the pull of true potential. An ecosystem meant more than just soil enrichment or decorative plants. It meant the realm itself would breathe, would become a living world capable of sustaining life.
The tree's soft glow seemed to pulse with patient expectation, as if it understood the magnitude of what it asked but trusted in their ability to rise to the challenge.
Whether he was ready or not, the path forward had been set. The World Tree had awakened, and with it, his destiny as architects of a new world awaits.
