Chapter 3: The Weight of a Heart
The news of Leo's contract spread through the Heart estate faster than a lightning strike. By the time Leo returned home, the air in the grand hall was thick with the scent of ozone—a sure sign that Adam Heart was struggling to contain his temper.
Leo walked in, the small, grey Sludge-Snail resting in a specialized glass terrarium buckled to his belt. To anyone else, it looked like he was carrying a piece of garden waste. To Leo, the Eye of Truth showed a pulsing gold core beneath that dull shell.
"Leo."
His father's voice was low, like distant thunder. Adam stood by the fireplace, his cape still shimmering with residual sparks from a recent Portal raid. Patricia sat on the sofa, her face a mask of worried concern rather than her usual doting smile.
"Dad," Leo greeted, keeping his voice steady.
"A Sludge-Snail, Leo? My son, the heir to the Storm Sovereign's legacy, contracted a floor-cleaner?" Adam turned, his eyes flashing with blue light. "I had a Storm-Eagle hatchling waiting for you. A beast that could soar through the portals! Why this... this pebble?"
"It's not just a snail, Dad," Leo said, stepping forward. "The books are wrong. The Academy is wrong. Every creature has a hidden path, and I can see them. This snail has a lineage that predates the Century War."
Adam sighed, the lightning around him fading into a weary slump of his shoulders. He didn't yell; he looked disappointed, which hurt Leo far more. "Son, I love your passion for beasts. But a Breeder without a powerful combat pet is just a target. If you can't protect yourself, you can't lead."
"Give him a chance, Adam," Patricia intervened softly, though she looked skeptical as she glanced at the snail. "Leo has always had a 'feel' for animals. Perhaps there is a reason."
"Fine," Adam said, turning away. "The Family Sparring Tournament is in one month. If that snail can't defeat even a basic Iron-Boar by then, you will annul the contract and take the Eagle. I won't have my son defenseless in a world of monsters."
Leo retreated to his private workshop, a room filled with microscopes, rare herbs, and jars of monster essence. He locked the door and placed the snail—whom he had named Grim—on the table.
"Ready, Grim?" Leo whispered.
The snail let out a soft shlurp sound, its eye-stalks bobbing.
[System Notification: Evolution Requirements Met]
Item 1: 10g Earth-Marrow (Located in the family vault). Item 2: A drop of Lightning-infused Heart Blood (Supplied). Method: Circular Osmosis Infusion.
Leo didn't need to break into the vault; as a son of the Heart family, he had a monthly allowance of materials. He pulled out a small vial of glowing, brown liquid—Earth-Marrow, the concentrated essence of the planet's crust.
Using his Eye of Truth, Leo saw the "Energy Veins" within Grim's body. Most Breeders blindly fed their pets, wasting 90% of the nutrient value. Leo, however, could see exactly where the energy needed to go.
He began the process. He carefully dripped the Earth-Marrow onto specific points of Grim's shell while simultaneously channeling a tiny spark of his own mana—the "Mimicry" talent allowing him to slightly imitate his father's lightning frequency.

Grim began to vibrate. The grey, mossy exterior cracked and peeled away. Underneath, the shell wasn't bone-colored anymore—it was a deep, matte black, etched with glowing violet runes that flickered like a storm in the night sky.
The snail grew from the size of a golf ball to the size of a dinner plate. Its "slime" was no longer sticky; it was a shimmering, liquid metal that hummed with kinetic energy.

Leo stared in awe. Grim looked like a piece of living jewelry—deadly, beautiful, and heavy. When Leo touched the shell, a tiny spark jumped to his finger. It didn't burn; it felt like a greeting.
"One month," Leo murmured, his eyes reflecting the violet glow of the runes. "In one month, Dad is going to see exactly what a 'floor-cleaner' can do."
The next morning, Leo took Grim to the back gardens. He spotted a large decorative boulder.
"Grim, use Kinetic Redirection," Leo commanded.
He picked up a heavy training hammer and swung it at the snail's shell. Normally, a snail would be crushed. But the moment the hammer struck, the violet runes flared bright. The force of the blow was sucked into the shell, and a split second later, a bolt of violet lightning shot out of the snail's body, shattering the decorative boulder into pebbles.
Leo grinned. He checked the Pet Encyclopedia.
Note: The Storm-Shell Devourer gains power by being hit. The harder the enemy strikes, the harder it dies.
"Leo!" A voice called out. It was Jud, running toward him, looking panicked. "You won't believe it! Marcus just contracted a Silver-tier 'Flame-Mane Lion' from his father's guild! He's telling everyone at school he's going to 'squash your bug' in the first round of the tournament!"
Leo looked at Grim, who was currently eating a piece of high-grade iron ore as if it were a leaf of lettuce.
"Let him try," Leo said. "I think Grim is still hungry."
