The strange green Slime they picked up three years ago… just spoke?
And it wasn't just any nonsense—it claimed it would rescue both the orthodox witches and its own Slime species from the clutches of the evil witches!
The young witches froze in stunned silence. Their wide-eyed expressions, filled with shock and curiosity, were undeniably adorable. Though they had secretly formed a coven to rebel against tyranny and dreamed of becoming heroes, in truth, they were still naive and inexperienced in the ways of the world.
This was the first time they had encountered a non-human creature capable of speech.
Melly's mouth formed a perfect "O" of astonishment. She gasped aloud.
"W-Wait! Could it be? Are you the intangible and formless god of wisdom from the legends—the thrice-exalted Hermes?"
The coven erupted in excitement.
The legendary Mercury, the celestial god of wisdom, was said to be capable of assuming any form to communicate with mortals.
Elizabeth, the group's leader, was more composed and mature than the rest. She quickly knelt and bowed respectfully.
"Great God of Wisdom Mercury, have you descended from the heavens to save your humble followers?"
Future Skywhale smiled to himself, tempted to go along with it. Pretending to be a god? Sure, why not. He was absolutely fine with a little divine impersonation.
But before he could nod in affirmation, Elizabeth's brows furrowed.
"No... Impossible. The true God of Wisdom wouldn't be so easily captured by witches. You had to fake your death to escape, and we were the ones who brought you back home!"
Future Skywhale froze, utterly embarrassed.
What happened to the usual tropes? Other people get to pretend to be gods when they cross into another world.
But me? I get turned into a squishy hostage. My Slime kin are tortured by witches. And when I try to act divine, I'm immediately exposed. What the hell?
With a sigh, he forced himself to speak honestly.
"I really can help you."
Elizabeth chuckled softly and picked him up, gently patting his jelly-like form.
"Little Slime, you've seen too little of the world. You have no idea how terrifying Medusa truly is. She's called the Absolute Empress Who Reigns Over Death. Even the Three Witches have been overshadowed by her. You… think you can defeat her?"
"Yes!" Future Skywhale declared proudly. "I will be the one to defeat the Great Empress Medusa! You don't understand yet, but we Slimes possess terrifying potential. Under my rule, we'll shatter the chains of oppression cast upon us by the Rose Kingdom!"
Pfft.
"What a cutie!"
"Look at that wiggly little feeler. Even his boasting is adorable!"
The girls burst into laughter as they surrounded the squishy, gleaming Slime. Their bright eyes sparkled with amusement.
Melly giggled and hugged him tightly, pressing him against her chest. She began pinching his soft, bouncy form.
"Slimes are just tiny, weak things! You guys can barely hop around, let alone fight. Your only value is being used for training by the witches. And you think you have potential?"
In the past three years, several people had tried integrating Slime blood into themselves. After much trial and error, someone finally succeeded… and grew an ahoge—a single, silly strand of hair. It granted freakish strength, sure, but the rest of the person was… disappointingly normal.
Slimes were still seen as bottom-tier creatures.
"You just don't understand!" Future Skywhale cried, puffing himself up as much as he could. "I have an incredibly powerful internal structure. Especially this feeler! It's the root of our species' strength—our lifeline, even!"
He looked around at the witches, hoping to be taken seriously.
"The essence of our entire race!"
"Of course! We get it now," Melly said, face bright red with laughter. "Your structure is super strong, and your feeler is your core. The essence of your race, right?"
Future Skywhale: "…"
He sighed internally.
They're impossible to reason with. What a headache…
I didn't evolve this specialized physiology just to be turned into a damn stress ball!
Still, he had a plan. He needed to acquire a sample of the "Blood of the Evil Eye," assimilate its genes, and become a true mage. That was the only way forward.
Not just to grow stronger—he had a ticking clock. His natural lifespan barely exceeded ten years.
It had taken him over three just to adapt to this world and learn the language.
He had no time to waste.
"If I can't assimilate another gene and start practicing magic, I'll die soon," he said.
"A Slime… practicing magic?"
The witches exchanged stunned glances.
Elizabeth lowered her voice. "Melly, how much money do we have left in our treasury?"
Melly's expression tightened. "Big sister, no! We've worked so hard to save that money for you to break through to Level Three!"
Elizabeth shook her head slowly.
"I may be the most talented among us, but even so, I can only hope to reach Level Three in my lifetime. Why not let our Slime try? He belongs to all of us. He's… our pet."
The sisters fell silent. They glanced at the little creature bouncing gently in place.
Melly hesitated. "We still have 3,521 rose coins."
Elizabeth did a quick tally aloud.
"A sample of the Evil Eye's Blood costs 300. The Potion of Magic Compatibility is 800. The Potion of Blood Compatibility is 1,300. And the Potion of Blood Stabilization… 1,400."
"We can't afford all that!"
The room became a flurry of debate.
These potions were sacred relics from the era of the Three Witches—designed to raise the success rate of blood assimilation and create powerful mages. But in modern times, such luxuries were out of reach for covens like theirs.
When they underwent the rite themselves, they had barely scraped together one low-grade potion. Risking their lives had been the only option.
Elizabeth remained firm.
"If we're going to do this, we'll do it properly. Without the potions, the success rate is too low. For women, the failure rate is already high. For men, it's ten times worse. For a Slime? It's probably even worse than that. We must give him every chance."
"If he dies… everything we've saved will be gone." Melly's voice cracked.
Future Skywhale, listening quietly, couldn't sit still any longer.
"Trust me! I won't die. I'm the King of the Slimes—the one destined to become the Sovereign Mage Emperor of this world!"
Elizabeth picked him up with a warm smile.
"All right, little King. When you become the ruler of the magical world… what title would suit you best? Hmm. How about… Adorable King?"
Future Skywhale was silent.
They clearly still didn't take him seriously.
But that was fine. He would prove it to them.
In the past three years, he had adjusted to this world. Despite being treated as a pet, he had formed a bond with these kind, hopeful girls. He would make them proud.
Ten days later, after enduring unimaginable pain, he survived the assimilation of the Blood of the Evil Eye.
One month later, he advanced to a Level One Wizard.
"A Level One Wizard?! After just one month?"
"He's incredible!"
The witches were overjoyed.
From that moment on, their cozy secret hideout stopped being a place for idle gossip and afternoon tea. They remembered their dream—to challenge the ruling tyrants—and began pouring all their resources into Future Skywhale's growth.
All seven of them worked tirelessly, hunting beasts in the great forest, saving every coin, and forgoing their own training.
Every rose coin went to the Slime.
And Future Skywhale never forgot their kindness. His days were filled with laughter and determination. He knew he had to grow stronger, patiently and steadily—he wasn't some foolhardy protagonist who threw himself into danger before he was ready.
If that made him a leech, so be it.
He was proud to be a leech.
After all, he'd spent years in the business world—shame wasn't in his vocabulary.
Still, leveling up was brutal. Each new rank brought exponential difficulty.
After one year, he reached Level Two.
After seven years, Level Three.
And after twenty long years…
He became a Level Four Wizard.
At that point, he stood at the threshold of power.
The witches of the Rose Sect—the tyrants of the world—were only at Level Five. And even though a single Level Five could decimate entire armies, Future Skywhale was no ordinary mage.
He was a Level Four Slime Wizard, with maxed-out proficiency in mechanical engineering and enough power to challenge even the mighty.
The world would soon learn that even the weakest creature could rise to the heavens.
