Chapter 190 — The Birth of a New Ecosystem
S.C. 1512 — Three Days Later
Hidden Island — Biological Sector, Outer Fields
The sun had barely climbed over the fog-covered island when Ren walked through the eastern cultivation zone.
Three days of testing had passed.
Three days of:
• Strengthening Serum (stable)
• Gene-Adjust Serum trials (slow but promising)
• Inert-Gene Awakening Serum (unstable but controlled in tiny doses)
Three days of goats, rabbits, birds, and fish adapting.
Now—
it was time to expand.
Not recklessly. Not suddenly.
Piece by piece. Animal by animal. Trait by trait.
A quiet evolution.
Zemo trotted beside Ren, proud of the growing territory like a small general inspecting troops.
Ren stopped at the first enclosure.
He exhaled softly.
"Let's begin the final inspection."
---
1. KS-9: The Prototype Warhound
A deep howl echoed from the northern enclosure.
The first experimental beast stood there—
a towering creature nearly two meters tall at the shoulder, still growing.
Not a monster. Not a mutation accident.
A carefully designed hybrid:
• enhanced muscles (wolf gene)
• strong bone density (tiger gene)
• high-speed twitch fibers (cheetah gene)
• reinforced lungs (compound-X boosted)
It looked like a giant wolf-hound, sleek, powerful, intimidating.
Yet when it saw Ren, it lowered its massive head gently.
Leo, who was standing nearby, waved.
"Boss! KS-9 ate double rations today. Still energetic."
Bram added proudly,
"He even pushed a one-ton log… alone."
Ren knelt and placed a hand on the beast's neck.
Stable temperature.
Calm pulse.
No aggression.
Good gait.
"Growth is balanced," Ren murmured. "We'll increase distance running tests tomorrow."
KS-9 barked thunderously, startling three workers.
Zemo growled back challengingly.
Ren sighed.
"Not today, Zemo."

2. The Soaring Giant — Pidgeon-Type Bird (Skycarver v1)
A rush of wind swept over the field.
Ren looked up—
and a massive shadow passed overhead.
A bird with a six-meter wingspan circled gracefully.
Not mythical. Just engineered:
• reinforced hollow bones
• stronger flight muscles
• expanded wing membranes
• sharper vision
Kiro stood near the aviary with a thick leather glove.
"She completed four laps around the island," he reported. "Stamina's amazing."
Ren nodded.
"She grows well. Keep her high-protein diet steady."
The bird swooped down, landing with practiced elegance.
Workers cheered quietly.
This one could one day carry riders.
But Ren wasn't rushing anything.
"Next month, we begin saddle testing," he said calmly.

3. Lightning Cat (S-Bolt Feline)
Near the forest edge, something blurred past.
A streak of silver-blue. Fast.
Zemo barked in surprise.
Leo shouted, "Boss! The lightning cat escaped again!"
It didn't escape.
It was running laps—fast ones.
The S-Bolt Feline darted around trees, leaving faint dust trails:
• enhanced legs
• shock-absorb tendons
• extremely fast twitch fibers
• heightened reflexes
Ren extended his telepathic sense lightly.
The cat's thoughts buzzed like sparks:
"Run—run—run—faster—wind—fun—run—"
Ren smiled faintly.
Good.
Healthy.
Energetic.
Just as intended.

4. Super Hen (Giga-Hen v1)
Bram called from the south pen.
"Boss!! SHE LAID ANOTHER ONE! LOOK!"
Ren approached.
The giant hen—standing almost five meters tall—peered at him with innocent eyes.
In front of her sat an egg the size of a large watermelon.
Leo whispered, "Breakfast is solved for the whole island…"
Ren inspected the hen:
• stable temperature
• strong legs
• no overexertion
• healthy diet response
"Good," Ren said. "Continue monitoring calcium intake."
The hen clucked proudly and nudged him gently.
Zemo ran behind Ren for cover.
Ren sighed again.
"It's just a hen, Zemo…"
---
5. Milk Titan Cow (Moo-Titan v1)
Next was the cattle enclosure.
A cow larger than any East Blue breed stood calmly grazing—
soft-eyed, gentle, with a massive lactation capacity enhanced by micro gene adjustments.
Makino stood beside her with a bucket.
"Ren… this cow… how do I say it…"
Ren raised a brow.
"Too much milk?"
Makino pointed at three full buckets already waiting.
"And she's not even halfway done."
Ren kneaded the cow's side gently.
Bone density normal.
Circulation excellent.
Digestive system strong.
"Good for children," Ren murmured.
Makino nodded.
"The village kids will grow healthier than ever."
---
6. Electric Sheep (Voltwool v1)
A soft baa echoed from a separate pen.
Then—
crackle.
Sparks danced across a sheep's wool.
Not dangerous. Just stored static.
This sheep naturally absorbed ambient charge and could release it in small bursts.
Leo kept a wooden rod between himself and the sheep.
"I touched her earlier… my hair didn't settle for ten minutes."
Ren inspected the creature.
Perfectly safe.
Good wool density.
Good electric storage.
"Next step: wool insulation tests," he noted.
---
7. Long-Leg Rabbit (Springer v1)
A rabbit hopped by—
then jumped.
Up.
Up.
Up.
Straight over a two-meter fence.
Kiro blinked.
"…I didn't think they'd jump that high."
Ren watched the rabbit land smoothly.
"Good tendon elasticity," he said. "Start distance-jump measurement later."
Zemo chased it.
Zemo failed.
The rabbit won.
---
8. Alo Fish (Rapid-Spawn Type)
At the shoreline, Bram waved frantically.
"Boss! You gotta see this!"
The sea pens were filled.
Bursting, actually.
Alo fish—large, nutrient-rich, and bred using micro-stimulation—were multiplying at high speed.
Bram looked horrified.
"I swear, Boss… they multiplied overnight."
Ren checked the water.
Stable.
Healthy.
Controlled growth.
"This will fix food shortage permanently," he said quietly.
Even Bram couldn't argue with that.
---
9. Dragon Earthworm (Terra-Worm v1)
In the soil pits, Leo gestured proudly.
The worms—0.5 to 2 meters long—slowly tunneled, breaking soil, leaving rich fertilizer behind.
Kiro examined the soil with Ren.
"Increased nitrogen. Higher mineral balance. Soil softer."
Ren nodded.
"These worms will renew every field on the island."
Zemo kept a cautious distance.
Smart fox.
---
10. Crystal Ant (Stone-Eater Type)
Ren entered the final enclosure.
Dozens of meter-sized ants crawled around, chewing stones.
Their excretion looked like glassy crystals and small gem clusters.
Makino stood stunned.
"…This is unbelievable."
Ren shook his head lightly.
"Just biology with adjustments."
Kiro collected the crystals.
"These alone could fund the island."
Ren didn't comment.
His focus stayed on safety and stability.
Every creature was behaving as predicted.
Balanced.
Healthy.
Controlled.
Exactly what he needed.

11. Sunset — The Arc Closes
As the sun set, Ren stood on a hill overlooking the island.
In one direction:
• towering cranes
• dry docks
• stone walls
• ship frames taking shape
In the other:
• KS-9 prowling
• giant hen nesting
• birds gliding
• rabbits leaping
• worms enriching the soil
• fish multiplying
A new ecosystem.
A new army.
A new foundation.
Zemo sat beside him.
Makino arrived with warm food.
Leo, Bram, Kiro, and dozens of refugees gathered below, laughing, working, training.
Ren inhaled quietly.
This island was alive now.
Stronger than ever.
The Island Building Arc had reached its end.
Tomorrow…
another future would begin.
