Two weeks after his agreement with the Weasley twins, Roy stood in front of the Liyue Store Research and Development Wing — a gleaming facility hidden deep within his pocket dimension.Polished marble floors reflected the soft blue glow of containment wards. Rows of enchanted apparatuses, cauldrons, rune printers, and spell-forging tables filled the air with a hum of controlled magic.
It was here that innovation met mischief.
Bela White and Nagini stood waiting as the large door hissed open and the twins entered behind Roy, their eyes wide as saucers.
Fred whispered, "Mate… this looks like Merlin's workshop and a joke shop had a baby."George added, "And that baby graduated with honors."
Roy smirked. "Welcome to the Liyue Magical Development Laboratory. You two are the first Hogwarts students to set foot here."
The Presentation Begins
Roy led them to the central table where several small crates lay neatly stacked, each marked with golden seals — prototypes the twins had been developing under his funding.
Bela handed Roy a clipboard. "Sir, these are the three prank models they submitted for initial testing."
Roy nodded and opened the first crate.Inside lay a tiny rubber duck, glowing faintly blue.
George grinned. "Behold! The Quacking Quill!"Fred added proudly, "Looks like a toy, but if anyone tries to cheat during exams, the quill starts quacking loud enough to alert every professor within fifty meters."
Roy blinked, then started laughing — genuinely laughing. "That's… actually brilliant."
He placed the quill on the testing pedestal, activated it, and purposely wrote 'test answer – wrong'.The duck quill quacked so violently that even Nagini had to suppress a smile.Bela rolled her eyes. "At least it's harmless."
"Harmless fun sells better than harmful revenge," Roy said lightly. "Approve this one for the student line."
The next crate hissed open to reveal what looked like colorful marbles.Fred's grin widened. "Mood Bombs! Throw one, and the entire room feels an emotion — joy, confusion, or drowsy calm. Lasts five minutes."
Roy flicked one toward a nearby training dummy.The marble burst in a puff of pastel light, and everyone instantly started giggling for no reason. Even Bela, usually composed, fought back laughter.
Roy wiped a tear from his eye. "Noted. Limit sales to underage joke-use only — and label it as 'For Entertainment Purposes.'"
The final crate held something far smaller — an enchanted chocolate frog box with odd runes carved along its rim.George said, "This one's our masterpiece. Echo Frog. It repeats any insult spoken near it — but louder, and with dramatic echoing."
Roy arched an eyebrow. "So, if Draco Malfoy tries to insult someone…?"
Fred smirked. "He'll get his own words thrown back tenfold."
Roy chuckled, testing it by saying, "You're late for class."
The frog immediately bellowed:
"YOU'RE LATE FOR CLASS! CLASS! CLASS!"
The room burst into laughter.
A Chairman's Vision
When the noise settled, Roy turned serious for a moment."These are good — better than good. But remember," he said, looking between the twins, "Liyue isn't just about selling jokes. It's about inspiring creativity. Magic should bring joy, not humiliation."
The twins nodded solemnly — a rare sight for both of them.George said, "Understood, boss."Fred added, "We'll make mischief with class."
Nagini smiled faintly. "They'll fit in just fine."
Roy gave the clipboard back to Bela. "File them under 'Prototype Humor Line — Project Weasley.' Approve production in limited batches for the school division."
Bela inclined her head. "Yes, Chairman."
After the Meeting
When the twins followed Roy out of the lab, they stopped halfway down the corridor, still a bit overwhelmed.Fred whispered, "He's not just rich. He's running an empire."George nodded. "And he just made us part of it."
Behind them, Roy walked calmly, hands in his pockets, faint smile on his lips.
"Laughter," he murmured, glancing toward the enchanted ceiling that reflected a glowing sky,"is the most underestimated kind of magic."
