With a loud explosion, colorful flames burst forth, unfolding into a firework lion in the air.
Fred and George hugged each other, cheering, "It's done! It's even more beautiful than we imagined! This gold is absolutely gorgeous! It's even more beautiful than Galleons!"
Vizette smiled too; the twins had a magical ability to easily spread happiness.
Actually, he didn't do much; his main task was to ensure the materials were fully utilized and that the final product had sufficiently vibrant colors.
However, in Fred and George's view, what Vizette did was the most significant contribution.
The twins didn't rest. After completing the experimental fireworks, they got busy again, working on even larger fireworks.
The two even wrote a patent document in a serious manner, and made Vizette put his name on it as well.
...
Inside the secret passage, Vizette was still thinking about the patent certificate. "You're planning to take this to the British Ministry of Magic and apply for a patent? Magic can be patented?"
He knew very little about the British Ministry of Magic; most of his knowledge came from secrets he'd heard from Luna.
For example, the Auror Office, elite wizards of the British Ministry of Magic, are actually part of the "Rotfang Conspiracy".
The so-called "Rotfang Conspiracy" refers to a scheme by someone who intends to use magic and gum disease to undermine the British Ministry of Magic from within.
The conspiracy sounded mysterious and incredibly magical, especially since it came from Luna's mouth, which Vizette believed wholeheartedly.
He wanted to gain a more comprehensive understanding of the "Rotfang Conspiracy," which naturally made him interested in the British Ministry of Magic itself.
"The Office of Comical Products Patents, that's what they do," Fred explained cheerfully. "It's a department under the Department of Magical Sports, so getting through shouldn't be too difficult."
"Mr. Bagman is easy to talk to. He was a professional hitter when he was young!" George chimed in, striking a hitting pose with a bat in hand.
"It seems like you know a lot of people at the British Ministry of Magic!" Vizette exclaimed.
Fred said sincerely, "You're our materials consultant now, someone we know..."
George put his arm around Vizette's shoulder and said with a grin, "That's someone you know!"
Seeing the twins' genuine smiles, Vizette also smiled.
Emerging from the secret passage, the three of them looked around and found the first floor unusually quiet, which aroused their suspicion.
"Let's go check out the auditorium first!" Vizette suggested.
The three immediately went to the auditorium, only to find it empty except for the black bats on the dome that were still active.
Just then, a sharp shout suddenly came from afar.
The three of them ran out of the Great Hall and saw Hermione, Ron, and Harry fleeing in panic at the end of the corridor not far away.
A huge shadow appeared, followed by a behemoth comparable to Hagrid.
Its massive body was as rough as granite, and its thick, gray-black skin was covered with moss and bumps.
With each step this behemoth took, the ground seemed to tremble.
Its arms were long, gripping a thick wooden stick, which it dragged on the ground with a screeching sound.
Fred immediately cheered, "A real surprise for Halloween?"
George exclaimed, "And a troll at that!"
Vizette frowned slightly and reminded him, "I just saw Ron! Did you guys notice?"
"Of course we noticed!" Fred and George said in unison. "Let's go check it out! Vizette, you stay where you are!"
Harry, his two friends, and others hid in a room, whereupon the troll attacked, smashing down a wall and burying them inside.
After doing all this, the troll suddenly sniffed and turned to walk towards Vizette...
Hearing the sound of the wall collapsing, Fred and George quickened their pace.
They approached the giant at incredible speed, their fireworks already lit, leaving a trail of sparks.
Things were developing too strangely. Vizette didn't know where the professors had gone, and it wasn't safe for him to be left alone in one place.
After a moment's thought, he didn't stay where he was. Instead, he gripped his wand tightly and followed the twins with extreme caution.
boom!
Fireworks shot out, leaving a dazzling trail of light in the corridor, and in the blink of an eye, they transformed into two magnificent firework lions.
Like true lions, they roared and pounced on the giant, engulfing it in a dazzling explosion of fireworks.
The giant seemed somewhat panicked by the sudden explosion and noise.
It was blown off balance and fell, its body tilting as it crashed into the wall beside it.
The walls could not withstand the weight of the giant, and the collapsing stones rained down on it.
Dust billowed, and the giant's massive body disappeared into the smoke and dust, leaving only its intermittent low growls.
George raised his hands and shouted, "Wow! Vizette, the fireworks you improved for us are really awesome!"
He waved his wand to disperse the smoke and dust, wanting to find out what was going on.
As the smoke cleared, the giant was found buried under rubble, its arm that had been gripping the wooden club still sticking out.
Fred chuckled and said, "This year's Halloween dinner is so innovative, I love it!"
"Can't you guys be serious for once? The situation is very critical..." Vizette said in a serious tone.
Before he could finish speaking, the exposed giant arm moved, swinging the wooden club at Fred.
"Fred, watch out!" Vizette shouted, immediately casting a modified summoning spell, "Fred, fly here!"
Ancient magical power surged into the wand, and it instantly lit up with a dazzling silver-blue light.
The light transformed into an arm, grabbed Fred's collar, and pulled him back, narrowly avoiding the giant's attack.
The giant, having failed in its attack, staggered to its feet, letting out a short, low growl.
"Ouch! He's passed out!" George realized the troll was acting strangely and quickly retreated while swinging his wand to unleash a beam of red light.
The red light struck the giant's chest, but had little effect, dissipating into tiny specks of light in the air.
The giant shook its potato-sized head and looked up in the direction where Vizette was.
Vizette felt a chill run down his spine; he had been targeted by the troll.
The giant let out a roar and moved swiftly.
It seemed even more agile than before, and with a "whoosh," it raised the wooden stick in its hand, swung it forward, and threw it straight at Vizette, who was furthest away.
Vizette was already on high alert. Seeing the wooden stick flying towards him, he didn't hesitate to cast a levitation spell, "Wingardium Leviosa!"
The levitation spell took effect; the originally menacing wooden stick was restrained by an invisible force and remained suspended in mid-air.
It was the magic that allowed him to easily restrain the wooden stick.
In the previous life, it would have been impossible to lift such a large wooden stick by human power alone.
Vizette's mind raced as he retrieved crucial information from the books in her mind—the troll's weakness was its head.
For most creatures, the head is a fatal weakness, and even trolls are no exception.
The troll's head is only the size of a potato, so hitting it accurately is no easy task.
Vizette understood this as well, and he added an extra spell to the levitation spell.
The wand glowed with a brilliant silver-blue light, and without hesitation, he swung the wand and flung the wooden stick forward.
