I, the leader of the esoteric sect, am doing great things in the infinite world!

Of course, this curse cannot ward off Avada Kedavra.

A dark glint flashed in Snape's eyes. He had been listening intently to Flitwick's explanation from the stage, and his mind, which had been dazed by the Killing Curse, was gradually starting to clear.

With Dumbledore present, there was no way Li Lin could use the Unforgivable Curse.

First, we need to get rid of these damn clouds.

He thought quickly and waved his wand forcefully.

“The wind whirls and swirls (ventus).”

The Hurricane Spell can not only disperse dense clouds and fog, but its powerful wind pressure can also suppress opponents, preventing them from making some precise movements.

The clouds and mist suddenly dissipated, but Li Lin was nowhere to be seen.

Snape's eyes widened, and he instinctively waved his wand, trying to create obstacles around him to slow down the "invisible enemy."

However, the moment he waved his wand, a hand encased in a transparent bubble appeared out of thin air and grasped his wand.

With just a little force, the wand will break in two.

Li Lin slowly materialized from the air in front of Snape. He didn't even use the hawthorn wand, but instead stretched out his right hand and pressed it against Snape's face, spreading his five fingers to block his vision.

The intense heat lingered between Li Lin's five fingers, yet remained dormant.

But all the wizards were certain that if Li Lin wanted, blazing flames would flow from his fingertips and quickly burn Snape to ashes.

This wizard duel, which was devoid of any martial ethics from the very beginning, has finally come to an end.

The dueling arena was completely silent. No one could believe that Severus Snape, the headmaster of Slytherin and a master of dark magic and its defenses, would lose so quickly and so miserably.

Even the lively Friev and Kettleburn couldn't utter a single word.

The difference in strength between Snape and this vice-principal was as great as the difference between them and Dumbledore.

"Albus, what happened? What kind of curse was that?"

Finally, Professor McGonagall couldn't resist her curiosity and asked Dumbledore.

She was, after all, a Gryffindor.

Dumbledore's snow-white beard trembled. He did not answer immediately, but instead signaled the end of the duel.

The dueling platform disappeared again, the tables and chairs moved back to their original positions, the lights came back on, and some simple food appeared on the table.

After the battle ended and Li Lin returned to normal, he stared with dead fish eyes and went back to his seat to eat and drink. He didn't eat breakfast.

Apart from Li Lin, all the other wizards had no appetite, while Snape sat restlessly to the side.

After witnessing this epoch-making duel, what normal wizard could still eat? Professor Flitwick excitedly surrounded Li Lin, trying to speak several times, but was stopped each time by Li Lin's slurping eating.

"All the spells Mr. Aatrox used, except for one Auror-only Disillusionment Charm, were low-level spells that students could learn."

"After casting the Cloudfall spell, Mr. Aatrox used his silent and wandless spellcasting skills to release a Bubble Head Charm and a Blazing Fire Charm, then cast an Illusion Charm on himself, thus bypassing the Ironclad Charm barrier and appearing before Snape."

Dumbledore explained it simply to Professor McGonagall.

As for shifting the release of the Bubble Head Spell from the top of the head to the palm of the hand to temporarily suppress the release of the raging flames, this is merely a variation of a low-level spell. Which professor here doesn't know this technique?

But to apply them to combat and use them flexibly... this genius-level creativity is simply amazing.

As for his previous "super magic technique" of pretending to use the Killing Curse while actually releasing other spells, it left other wizards in awe.

Of course, they didn't know that Li Lin didn't need to say the correct incantation when using these secret spells.

The essence of the art of the invisible is the correct way to utilize the laws of the world.

After a brief pause, Dumbledore finally concluded on the nature of the duel: "Although our Vice-Headmaster, Mr. Aatrox, completely overwhelmed Mr. Severus Snape, Mr. Aatrox undoubtedly violated the rules of wizarding duels, therefore..."

"The victor of the wizarding duel shall be Mr. Severus Snape."

108 You don't use the secret techniques at all to do your job properly, do you?

As evening approached, Qiu Zhang disembarked from the Hogwarts Express.

The prefects of each house have taken to the platform to ensure the safe arrival of all their new students at Hogwarts.

When Qiu Zhang walked out with her suitcase, she attracted everyone's attention.

"Beautiful, damn, so beautiful."

George and Fred stared in disbelief at the quiet Cho Chang, and after a moment, they spoke in unison.

The students around Qiu Zhang eagerly surrounded him, and even the usually stern class leaders smiled.

Just then, a somewhat gruff voice came from the other end: "First-grade students, come over here, don't be shy!"

"First-grade students, gather here immediately!"

A group of freshmen seemed startled. They turned to look at the source of the sound, where a huge outline was clearly visible in the hazy darkness.

“Oh, it’s Rubeus Hagrid.” George and Fred shrugged, looking at the bewildered first-year students with mischievous grins. “They have no idea what’s going to happen next.”

The Weasley twins laughed heartily and left first, leaving the bewildered freshmen to head towards Hagrid, the gamekeeper at Hogwarts.

When Cho Chang saw Hagrid's enormous body, she couldn't help but widen her eyes. She never imagined that someone could grow to be so big.

“That’s Hagrid, Rubeus Hagrid, he’s the gamekeeper at Hogwarts,” Marietta Eckmore whispered to Cho Chang. “They say he’s a half-giant.”

Marietta Eckmore is a friend that Cho Chang met on the train. She has reddish blonde curls and seems to have a lively personality.

Her mother was a civil servant in the Frodo Network Management Bureau of the Department of Magical Transportation and had previously attended Hogwarts.

"Are all the freshmen here?" Hagrid's gruff voice rang out again as he called to the freshmen, carrying a huge oil lamp. "All first-year students, follow me. We need to take a boat. Hurry up and catch up."

It has always been a tradition for new students to travel to the magic school by ship. The four founders of Hogwarts also traveled to Hogwarts Castle by ship.

Hagrid led the young wizards to the shore of the Black Lake. The soft light from the oil lamps illuminated the small boats, and lanterns with swaying lights were placed on tree stumps along the lake.

"Put your lanterns at the bow of your boats, and four people in each boat!" Hagrid, carrying his lantern, was the first to sit in a boat. Cho Chang keenly noticed that when Hagrid sat down, the small boat rocked violently.

“Oh my god, I’m really worried he’ll capsize,” Marietta said in a low voice.

Hagrid ignored the whispers of the first-year wizards, raised his palm, and the calm surface of the Black Lake began to ripple, the small boat rocking and swaying forward.

As the young wizards followed one by one away from the lakeside, the enormous castle perched on the cliff came into view. Brilliant lights shone from the rows of ancient castles, reflected in the waters of the Black Lake, making it impossible to distinguish where the water ended and the sky began.

"My God, that's Hogwarts."

All the young wizards were awestruck by the magnificent sight.

“Yes, this is Hogwarts.” Hagrid heard the young wizard beside him speak, and he held up his lamp in admiration. “How beautiful… what’s going on?”

The small boat was rocking a bit.

The calm black lake began to swell.

Hagrid raised his lantern, and the oil began to burn fiercely, emitting a bright light to dispel the thick darkness.

"Merlin's beard!" Hagrid exclaimed.

A chilling wind swept over them, followed by the cold, foul-smelling waters of the Black Lake. A massive, bluish-gray tentacle emerged from the lakebed, its countless grotesque suckers, each the size of a human head, expanding and contracting erratically to form indescribable, blasphemous patterns.

"Wow, this is so exciting!" The new students, who knew nothing about Hogwarts, were fearless and thought it was a surprise prepared by the school.

"Don't look at that tentacle!" Cho Chang covered Marietta's eyes and shouted to the other two young wizards, "Turn around, don't look at that tentacle!"

No matter how loudly Qiu Zhang shouted, the area she could protect was only a few nearby boats. Soon, an excited little wizard, after staring at the tentacles, went crazy and wanted to jump into the lake.

As more and more young wizards fell into brief madness, a second and third tentacle began to emerge from the bottom of the lake, and a heavy shadow continued to loom.

Even more chillingly, large amounts of mist began to form on the surface of the Black Lake, and even without looking directly at the tentacles, the young wizards who inhaled the mist began to experience various hallucinations.

In the auditorium, Li Lin, who had been disqualified for his lack of martial ethics, was trying to get some phoenix feathers from Dumbledore.

Suddenly he frowned and stopped bothering Dumbledore.

On the dark green table that rose in front of them, a brand new card appeared out of nowhere.

Against a gray-black background, a huge squid kept changing its position. When Li Lin turned his attention to it, ripples spread around the card.

[Alien Species: Animagus Giant Squid Gryffindor.]

[Nature/Appearance: Blade, Heart]

[Rank: Third Mark]

Sometimes, when a wizard's lifespan is nearing its end, they may transform into another form to survive due to the influence of their bloodline and spells. It has existed for a thousand years in a state of having shed its old self; perhaps it shouldn't be called Gryffindor.

The alien species is currently affected by an unknown force!

Then a huge shriek came from outside Hogwarts, passing through the barrier of the school without hindrance and exploding in the Great Hall.

"What happened?" Minerva McGonagall rose from the table and drew her wand.

Dumbledore's expression quickly turned serious, and he turned to look at Li Lin: "Mr. Aatrox, I think we both have to go together."

The effects of that day have not completely subsided, but are deeply buried within the giant squid's body, only to erupt all at once today.

It can only be said that even if Gryffindor had completely become a mutant, he would still be a master at causing trouble.

When Dumbledore, Li Lin, and the others walked out of the Great Hall and looked down at the Black Lake from the cliff, a huge flood peak had already risen from all directions, and six huge tentacles emerged from the bottom of the lake, enveloping the first-year students in an encirclement.

Fortunately, no students fell into the water; the Hogwarts boats were enchanted so they wouldn't be swallowed by the flood.

“We’re not too late.” Dumbledore drew his wand, pointed it at the giant squid’s tentacles, and said in a deep voice, “Finite Incantatem.”
