Spell: Reparo!

Small and large light spots floated beneath the ceiling, illuminating the office as if it were daytime.

Voldemort crouched low, squinting as he flipped through the Book of Spells.

Time had entered the early morning hours. His eyes were tired and blurry, but he still didn't want to rest—he wanted to find a suitable spell as soon as possible to research the source of magic in Dumbledore's conjecture.

Having traversed the magical world for over ten years and gained freedom for several months, he had desperately studied magic during this time, only to prove one thing…

His magical talent was mediocre.

The magic of this world had been broken down like the trades after the Industrial Revolution in the Muggle world, entering an era of specialized, refined division of labor.

Even children with mediocre talent could achieve respectable results if they were willing to work hard.

But he, with mediocre talent, happened to possess a part of Voldemort's remnant soul…

Voldemort's remnant soul's understanding and application of dark magic were far beyond his main soul.

This made him incredibly envious, and he always wanted to delve into the study of dark magic, but he could only hesitate—researching dark magic under Old Bee's watchful eye? He'd have to be insane to do that.

Retrieving more of Voldemort's soul from the Horcruxes should improve his magical talent.

But he didn't know how to retrieve the souls from the Horcruxes; the remnant soul didn't contain such memories—this was a future research topic for him, but he currently lacked the environment and ability.

Under these circumstances, Voldemort's original intention was to solidify his magical theory and enhance his magical application abilities.

However, the unexpected appearance of "Dumbledore's Conjecture" gave him a new direction—since he wasn't a genius, he would chase after a genius's footsteps.

Therefore, in the dead of night at Hogwarts, while the well-behaved students slept and the mischievous ones roamed, he still endured his drowsiness, striving to find a glimmer of hope.

"Enemy Fall Trap, a protective spell, can affect multiple people, but the effect…"

"Flame Blaze, an elemental spell, doesn't align with the overall direction of the Wizarding World, abandon…"

"Confundus Charm, because of curses, I have some insights into this, I'll keep it as a backup option…"

He went through the spells one by one, Voldemort constantly making judgments in his mind. Most were abandoned, and some were recorded as backup options in his notebook.

Another half hour passed like this, and he was so drowsy he could barely function—he had only slept for a little over an hour last night, and now he had stayed up until late again, his mind utterly exhausted.

"Just a few more, just a few more…"

Voldemort thought, his finger slowly moving down the book, reading spells one by one.

"Expecto Patronum, magical enough, mobilizes emotions sufficiently, backup…"

"Reparo, a household charm, not very significant…"

"Scouring Charm, still household… wait…"

Voldemort's finger stopped. He shook his head vigorously, then blinked, feeling not clear-headed enough. He picked up the nearby water cup and took a large gulp.

He finally felt a bit more alert and gently moved his finger upward.

"Reparo, a household spell, but it's magical, restoring everything to its original state…"

Voldemort murmured, his finger finally stopping again on the words "Reparo spell," and he began to carefully read the small print below:

Spell: Reparo.

Can be used to seamlessly repair most damaged objects.

The spell was invented in 1754 by Olavella Nutley, an employee of the British Ministry of Magic's Prohibition of the Misuse of Magic Office. At the time of its invention, it was used to repair the Roman Colosseum, which had been accidentally destroyed.

Effect: The Reparo spell is effective on most materials.

Restrictions: The Reparo spell can only be used on inanimate objects. Using it on living beings will cause severe scarring, irreversible damage, or even death.

Unrepairable:

The Reparo spell cannot repair damage caused by rare and powerful curses.

The Reparo spell cannot repair objects imbued with powerful or complex magic.

The Reparo spell can perfectly repair the container itself, but spilled liquids cannot be recovered.

The Reparo spell cannot repair wands, which are extremely sensitive to magic…

The content about the Reparo spell took up a full half-page, and the font was very small, but there was no in-depth analysis or explanation of the spell itself.

The book's content was mostly about the spell's conditions of use and restrictions. Although the Book of Spells was comprehensive in its recording of spells, it lacked depth.

There wasn't a single annotation on the formation or decomposition of the spells themselves.

Lifting his head from the desk, Voldemort frowned and pondered for a moment. He picked up the wand on his desk and gently waved it…

"Reparo."

A spell of yellow and purple hues slowly drifted from the wand. Under Voldemort's control, this ball of magical light hovered in front of him.

He squinted and observed carefully but couldn't glean any useful information.

"Zzzla…"

He tore a page from his notebook, folded it, and ripped it several times, finally crumpling it into a ball and tossing it into the magical light.

"Whoosh~~"

As if a gentle breeze had passed, the paper ball unfolded in reverse, and countless paper scraps drifted in the yellow-purple light, piecing themselves together with the spell's effect.

At first, there were many cracks, but as the yellow-purple light seeped into it, the cracks disappeared at a visible speed and quickly returned to their original state.

Even the creases on it vanished in an instant.

"Time Reversal?"

Voldemort murmured softly, reaching out to take the paper. He rubbed it carefully and held it up to the light for a moment, finding no trace of it being pieced together.

Placing the paper back in its original position, he pointed his wand at the notebook...

"Reparo."

The yellow-purple light shot out again, instantly affecting the torn edges of the paper and notebook. Then, the light slowly faded, and the page returned to its original state.

Seamless, with no sign of anything unusual.

"A household spell, but very magical. Is this a characteristic of Time Reversal?"

Voldemort murmured, unable to resist picking up a small ornament on the table – a crystal London Bridge model, a trinket from the Muggle world.

"Crack."

Without hesitation, he smashed it onto the floor. The glass crystal shattered, breaking into tiny fragments that scattered across the ground.

"Reparo."

He pointed his wand at a larger piece of the fragment, and the yellow-purple light shot into it instantly.

The scene of time flowing backward appeared once more. Tiny fragments flew out from under the table and beside the stool, quickly reassembling into a crystal London Bridge.

"London Bridge, fly here."

He twirled his wand, and the newly repaired crystal London Bridge immediately flew into Voldemort's hand.

Holding the ornament, he examined it closely against the light...

"Not a trace, no different than before."

He couldn't help but murmur softly, recalling the process of the ornament's restoration.

The weariness in his eyes slowly gave way to a glimmer of excitement.

Reparo should be magical enough, shouldn't it... Voldemort mused, fiddling with his wand.

He truly hadn't expected that, after much deliberation, the spell he'd chosen would be a household spell.

But as he thought, this spell was magical enough, wasn't it?
