In the Gryffindor common room, as the rooster crowed, Light continued to speak in front of all the young lions.
"You can go back and get recording devices. This rooster will keep crowing in the common room until dawn."
Shortly after he said this, the sound of someone pushing open the door echoed in the common room, catching everyone's attention.
There were Harry Potter and his two friends sneaking in quietly.
Seeing that everyone's attention was drawn to Harry Potter's sudden appearance, Light whispered to Neville,
"Harry Potter is a Parselmouths. He won't be in as much danger when facing the basilisk. Can I give this reputation to him?"
Looking at Light's sincere eyes, Neville waved his hands quickly. "It's okay, it's okay. You're the one who discovered the truth. I didn't know anything in the first place."
After getting Neville's approval, Light felt relieved. He turned around and walked towards Harry Potter and his friends.
Harry Potter and his two friends were trying to sneak in. They were puzzled. They wondered why the common room was so quiet, with only the occasional rooster's crow.
When the three of them looked up and found that everyone's eyes were on them, they couldn't help but panic.
At this time, Light walked up to Harry Potter. With one hand holding his wand to his throat and the other raising Harry Potter's hand, he said,
"This information was discovered by the savior, Harry Potter, in The Library. Maybe that's why he learned Parselmouths."
After learning the whole story, the young lions were relieved and got excited.
Harry Potter and his two friends were completely confused. Meanwhile, an explosion of screams and cheers erupted in the common room. The students shouted, "The savior, the savior..."
They all rushed over, throwing Harry Potter up into the air and then catching him.
"What's going on??" Ron was completely bewildered and looked at Harry Potter, who was being tossed in the air.
"What's going on, Light?" Hermione grabbed Light and asked in a low voice.
Light pulled Ron, who was still in a daze, and explained together, "I told them what attacked the students and its weakness."
Ron was extremely shocked and asked quickly, "What attacked the students and what are its weaknesses?"
"It's the basilisk that attacked the people. Its weakness is the rooster's crow."
Hearing Light's words, Hermione immediately understood and murmured, "The basilisk. That explains it, that explains it."
"Then why did they carry Harry Potter over there?"
While listening to Light's information with his ears, Ron stared at Harry Potter, who was being tossed up and down, and asked anxiously.
"Maybe they think Harry Potter learned Parselmouths when he was investigating the basilisk," Light said evasively.
Amid all the noise, even very late at night, there were still people holding devices to record the rooster's crow.
The Weasley twins directly found Light and discussed whether they should sell recordings of the rooster's crow.
Light looked at the Weasley twins in surprise and thought to himself, "Business wizards! They even thought of this idea!"
Amid the strange laughter of the three, information about the basilisk and devices recording the rooster's crow spread throughout the school the next day.
This caused countless young wizards to verify the information regarding the basilisk.
They also wanted to see if they could learn Parselmouths like Harry Potter. As a result, The Library was packed like sardines.
After confirming that the basilisk's weakness was indeed the rooster's crow, the young wizards' fear of the Attack dropped to its lowest point.
Similarly, the recordings of the rooster's crow prepared by Light and the Weasley twins sold like hotcakes.
At night, the rooster's crow almost echoed throughout the castle, and during this period, the basilisk never came out.
Because of this, the young wizards went to The Library even more frequently.
During this time, Professor Sprout also issued a notice that the mandrake roots were almost fully grown, and those who had been Petrification would soon be cured.
With the professor's guarantee, the basilisk storm gradually subsided.
It's a pity that the market for the recordings of the rooster's crow has become saturated, and this money - making method is no longer viable.
However, neither Light nor the Weasley twins felt too bad about it.
Seizing this opportunity, the Weasley twins introduced skip - class toffees, which made young wizards skip classes daily and flock to The Library.
In response, Light could only clap his hands and shout, "That's sick! No wonder you'll open a shop and make a fortune in the future."
After a day of classes, Light went to the Room of Requirement as usual. After practicing Apparition for a while, he stopped, feeling irritated.
Slumping in a chair in the room, Light, calculating the days, muttered under his breath,
"The potion has completed its fermentation. I haven't earned any Mileage Points during this period!"
"It seems I have to destroy it to complete this final piece of the puzzle."
After consideration, Light took out the box containing the Horcruxes. Looking at the box in his hand, he said softly,
"What a pity. I was thinking about whether I could separate Voldemort's soul and then kill it to preserve this treasure of Ravenclaw."
Not dwelling on the pity, after making the decision, Light picked up the box and turned towards the door.
"I need an open room!"
Pushing the door open again, an endless expanse appeared before him.
Opening the wooden box, Light looked at the Horcruxes - The Diadem of Ravenclaw inside. The familiar murmur echoed in his mind.
After confirming it was the original, Light closed the wooden box, placed it on the ground, and took out his wand.
"Summon Fiendfyre curse!"
Violent Fiendfyre curse gushed out of the wand and rushed towards the box on the ground.
Shortly after the Fiendfyre curse engulfed the box, black smoke billowed from the flames. It seemed as if the black smoke was resisting the Fiendfyre curse's devouring.
Seeing this, Light increased his Magic Power output, and more Fiendfyre curse rushed out of the wand.
The black smoke suddenly shot up into the sky, wrapping around the Fiendfyre curse in the air. It transformed into a head similar to a snake's, a bald head without a nose, and roared as it lunged at Light.
"All Spells End!"
Light, who had been prepared, bent his knees slightly, held his wand, and slammed it on the ground.
Suddenly, countless orange lights gushed out from the ground, transforming into rays that wrapped around the approaching Fiendfyre curse.
It was as if the Fiendfyre curse had gotten out of control, as if it had a soul. It struggled within the layers of light and even shattered several restraints.
Facing the increasingly violent struggle of the Fiendfyre curse, Light, with sweat on his forehead, could only increase his output of Magic Power.
The constantly gushing light forced the Fiendfyre curse to retreat and gradually enveloped it.
Finally, the serpentine Fiendfyre curse let out an unwilling hiss and vanished into nothingness.
Gasping for breath, Light shook his head and smiled wryly. "I didn't expect that an out - of - control Fiendfyre curse combined with Voldemort would be this difficult to handle."
"However, it's also because my level of White Magic is relatively low."
At this moment, the message from the stone stele finally arrived: "Completed the mileage task 'Killing one Dark Lord', Mileage Points increased by 1."
