I've already become a Hogwarts professor, and the system only just appeared.

But Su Yu knew that Professor McGonagall used the Transfiguration Charm, a very sophisticated transformation, and felt that there was a big gap between him and her.

Su Yu did not give up. He used the same method again and fired another explosive spell at the ground in front of Professor McGonagall.

But Professor McGonagall was not Lockhart; she flicked her wand and took small, quick steps backward.

The butterflies that were flying in the air quickly expanded and grew larger, combining to form a shield that stood in front of Professor McGonagall.

With a loud bang, the explosive spell was quite powerful, but it only left a dent in the shield; nothing else was left.

Professor McGonagall then launched an attack. She lightly tapped her wand on the shield, and the shield changed shape again, instantly transforming into a striped tiger that pounced on Su Yu.

Wow, Professor McGonagall's Transfiguration is incredibly fast and accurate. Seeing the tiger pouncing on him, Su Yu patted the badge on his chest.

This badge was specially made to counter Voldemort's Killing Curse. Initially, it contained three hexagonal metal pieces that could expand in size and float around the user to ward off the curse after being summoned.

Later, Su Yu upgraded it. Now, when activated, three small ravens with a metallic sheen fly out. They have sharp beaks and scimitar-like wings, which can be used for both defense and offense.

Under Su Yu's control of his magic wand, the three little ravens grew larger in the wind and quickly flew towards the tiger, cutting it into three pieces as swiftly as a knife cutting through tangled hemp.

The tiger was decapitated, blood spurting everywhere. The sight terrified the young wizards in the audience, who screamed in terror. But the three ravens continued their charge, heading straight for Professor McGonagall.

Professor McGonagall remained calm, a slight smile playing on her lips as she praised, "A very good alchemical tool!"

The reason for this is that Professor McGonagall discovered that her magic could not affect the three ravens. It must be that Su Yu protected their magic frequency, making them only react to the specific magic of a certain person.

She was right. This was a technology that Su Yu discovered while studying the remains of the Jumping Pot. This technology was very important. Just imagine how frustrating it would be if the alchemical artifact you summoned during battle suddenly turned against you and was controlled by someone else.

It's practically like being cuckolded. With this technology, Su Yu no longer has to worry about this happening.

Professor McGonagall continued her actions, first using the Ironclad Charm to swat away three ravens, then continuing to wave her wand, transforming the tiger's body, which had been cut into four pieces, into four giant pythons.

Three of them lunged at Su Yu, while the other returned to Professor McGonagall's side, surrounding her and protecting her.

Su Yu was dumbfounded and thought to himself: This is a tiger, not an earthworm. Cutting it into four pieces doesn't make it into four. That's not scientific at all.

Despite his complaints, Su Yu didn't dare to stop for a moment. He fired three petrification spells, freezing all three giant pythons in place.

At the same time, the three ravens changed direction and charged at Professor McGonagall again. This time, the three ravens crashed into the giant python next to Professor McGonagall, only causing a shower of sparks, without causing any damage.

Su Yu immediately recognized Professor McGonagall's method of localized metallization, but it was useless to him. Maintaining the life of the shapeshifter while performing localized metallization defense was a high-level shapeshifting technique that he couldn't use.

Then Professor McGonagall unleashed an explosive spell, which Su Yu hurriedly dodged. However, Professor McGonagall's target was not him, but the petrified giant python in front of him.

With a bang, stone chips flew everywhere, and the three giant pythons were blasted into thousands of pieces. Su Yu saw some of the stones starting to gather towards Professor McGonagall and immediately understood her intention.

He quickly recalled the three ravens, while Su Yu unleashed his full magical power, vying with Professor McGonagall for control of the stones.

Chapter 94 Transfiguration Showdown (Part 2)

“Su, your move just now was very imaginative. I’ll give it a try!” Professor McGonagall said with a smile, like a wise mentor instructing a junior.

As Professor McGonagall waved her wand, the rubble gradually transformed into sharp daggers. Perhaps in Professor McGonagall's opinion, the longswords Su Yu had made were not as useful as the daggers.

Su Yu's posture was similar to Professor McGonagall's, also surrounded by a large number of pebbles. However, the number of pebbles around him was only about half that of Professor McGonagall, which was a hard difference in magical power.

Su Yu waved his wand as well, and the rubble transformed into longswords, while the three ravens transformed into three shields, surrounding Su Yu.

Next, the two pointed their wands forward, and two streams of swords, like two long dragons, rushed towards each other.

The swords clashed and collided in the center of the dueling arena, producing clanging sounds. Longswords and daggers were constantly being knocked away, while daggers and longswords broke through the barriers and rushed towards the two.

However, only one or two longswords were aimed at Professor McGonagall, while dozens or even hundreds of daggers were aimed at Su Yu.

Fortunately, Su Yu was protected by the Raven Shield and was not injured. After a round of attacks, Su Yu found that he had lost some of his longswords, while Professor McGonagall had gained dozens more.

Is he ultimately destined to be cuckolded? Su Yu felt a little sad, but Professor McGonagall obviously didn't care about that. She thought for a moment and said, "This kind of power seems a bit one-dimensional. Why not add something else?"

As she spoke, Professor McGonagall waved her wand again, and flames immediately burst forth from the daggers and longswords beside her.

Su Yu was completely impressed that someone could do that. As expected of Professor McGonagall, her skill in converting matter and energy was truly remarkable.

Seeing the fiery sword stream rushing towards him again, Su Yu's ordinary sword stream was completely swallowed up without any resistance. He sighed, there was no other way but to use his items!

Reaching into his seamless extension bag, Su Yu pulled out a magically modified Gatling gun. Surrounded by three Raven Shields, he secured the Gatling gun to his waist and pulled the trigger.

The gun barrel spun, and the next moment, a dense barrage of spells shot out from the barrel, at least 50 per second, all of them disarming spells.

The spell crashed into Professor McGonagall's fiery sword flow, and daggers and longswords were immediately sent flying in all directions.

In just 15 seconds, Professor McGonagall's fiery sword stream was dispersed, and the Gatling gun muzzle moved down, its target becoming Professor McGonagall.

Professor McGonagall quickly waved her wand, turning the giant python circling around her into a stone wall to block the dense, rain-like spells.

Another 15 seconds later, the dueling arena was a complete mess. Thousands of daggers and longswords were scattered haphazardly, flames burned on the daggers, and a large hole was broken in the wall in front of Professor McGonagall. Anyone who didn't know better would think this was some Muggle battlefield.

However, Professor McGonagall herself was not attacked; she remained elegant, though her expression showed slight fatigue.

As for Su Yu, he was lying on the ground, sprawled out and breathing heavily. His magic Gatling gun was lying to the side, and his raven shield had also fallen to the ground.

In fact, Su Yu had conceived of the magic Gatling gun a long time ago, and even made a finished product.

Unfortunately, his magic power was too low at that time, and his magic output could not keep up with the speed of casting spells. Not only were the spells he cast very weak, but after firing a few shots, there were also blanks. The actual effect was not as good as a magic pistol.

Moreover, although wizards don't have mana bars, casting spells still consumes mental and physical energy, which they can't sustain at all. In the end, this thing can only lie in the Seamless Stretch Bag collecting dust.

Su Yu's magic power has now reached LV8, so he decided to try the weapon again. Judging from the effect, it is quite good. The power of each spell can be maintained at the level of LV5-LV6.

However, his stamina was far inferior. In less than half a minute, Su Yu felt that his body was about to be completely drained.

"I admit defeat..." Su Yu reluctantly raised one hand, ready to concede.

But Professor McGonagall interrupted her, saying first, "I concede!"

"Wow!" The audience erupted in commotion. Harry, sitting in the audience, asked in bewilderment, "Why? Professor McGonagall clearly overpowered Professor Sue. Even though Professor Sue's gadget was terrifying, Professor McGonagall handled it with ease."

As if hearing Harry's question, Professor McGonagall said, "I'm exhausted and can't continue the game. Professor Sue's performance has exceeded my expectations. I think he will definitely become a great wizard in the future."

As she spoke, Professor McGonagall waved her wand, restoring the dueling arena to its original state, showing no signs of exhaustion whatsoever.

Everyone understood that Professor McGonagall was clearly going easy on her, or rather, giving the younger students more opportunities to shine. So the students in the audience immediately burst into enthusiastic applause for Professor McGonagall.

Ding! Congratulations on defeating Professor McGonagall in the Wizarding Duel. You can choose one of the following three feats as a reward.

1. Transfiguration Genius: The transformation magic you cast consumes 15% less power.

2. Size at Will: Increases the efficiency of your Polymorph spell conversion by 25%.

3. Heart of Nature: Allows you to remain in the Animagus state for extended periods without being influenced by animal instincts.

Unexpectedly, Professor McGonagall deliberately let him off the hook, and the system recognized it. Su Yu quickly checked the rewards. The third one was obvious. Professor McGonagall always liked to maintain her cat form, which was probably influenced by the Heart of Nature.

The first and second ones look almost identical. Su Yu clicked on them and studied them carefully. The first feat's effect was simple and straightforward: it directly reduced the cost when casting Polymorph.

The second specialty is somewhat ambiguous. According to Gump's Transformation Law, Transformation Charms cannot conjure matter out of thin air, but when transforming a small object into a large one, magic can be used to convert and fill it.

So the second specialty comes into play during this transition process, and it's hard to say whether the first or the second is better.

After some deliberation, Su Yu finally chose his second specialty. The reason was simple: the name "Da Xiao Ru Yi" (meaning "Big and Small as You Like") sounded really cool.

After choosing his reward, Su Yu took a while to get up. He went to Snape's side and said, "I've made it to the finals. What are your plans?"

Snape was also a little embarrassed. He originally thought that Su Yu would definitely not make it to the finals, so he pretended to be confident in advance. Who would have thought that Professor McGonagall would let him win?

He gave Professor McGonagall a resentful look, then raised his head high again and said, "I won't hold back against you in the finals!"

Chapter 95 Finals

The second match was Snape versus Flitwick. The Transfiguration battle had the audience on the edge of their seats, leaving them wanting more.

When the two stepped onto the stage, the young wizards immediately cheered. Those with magic phones raised their phones, determined to film the entire battle.

Snape and Lockhart bowed as usual, separated, and then assumed their positions. When Lockhart counted to three, the two launched their attacks simultaneously.

It must be said that both of them were quite skilled in spellcasting. They fired spells at each other, only to have them deflected and swerved by their own casually swung miniature Ironclad Spells.

If the previous scene featured extreme transformation effects, then this scene features extreme lighting and shadow effects, with various colors of light flashing at least five to ten times per second.

The spells failed to hit their opponents, instead bouncing off the protective shield at the edge of the dueling arena, creating ripples that raised concerns about its strength.

Suddenly, Snape casually flicked a spell and then unleashed a petrification spell with his other hand. The spell shot out with a long red trail of flame, but Professor Flitwick did not rush to retaliate. Instead, he took off running towards Snape instead of retreating.

Despite his short legs, Professor Flitwick was surprisingly fast. In the blink of an eye, he encountered Snape's spell.

Professor Flitwick kicked off with his calf and jumped up, but Su Yu thought that was suicide, because once a person leaves the ground, there is nothing to hold onto and no way to adjust their position.

Is Professor Flitwick throwing the game too? But the match has only just begun; isn't it a bit too much to throw it at this point?

Sure enough, the next moment Snape raised his wand, slightly altering the direction of the spell, and shot it toward Professor Flitwick in the air.

But Professor Flitwick remained completely unfazed, gently tapping his wand forward and casting a small Armor Charm in front of him.

Next, he stepped on the iron armor charm with one foot, adjusted his direction, and met Snape's petrification charm head-on.

With a bang, the petrification spell struck the armored spell beneath Flitwick's feet, exploding into a burst of red light, and a visible shockwave rippled outwards in front of the armored spell.

Professor Flitwick used the momentum to leap up again, soaring above Snape's head and pointing his wand at Snape from his superior position.

Seeing this, all the young wizards present were utterly astonished. They had never imagined that the Ironclad Charm could be used in such a way; it was truly amazing.

Su Yu was one of them, but Professor McGonagall next to him smiled and said, "This is a little trick that Professor Flitwick practiced in the dueling arena. It requires a high level of skill in casting the Ironclad Charm, the angle, and the judgment of magic output."

Su Yu paused for a second before asking a question that struck at the heart of the matter: "But why did Professor Flitwick jump so high?"

Professor McGonagall was taken aback for a moment, then said, "He probably wanted to jump up and hit the other person on the head."

While the two were talking, Professor Flitwick had already cast his spell: "Sandstorm!"

A gust of wind shot out from the tip of Professor Flitwick's wand, carrying countless tiny grains of sand and sharp fragments of stone. It was so fast that being hit by it would certainly not be pleasant.

In his haste, Snape had no choice but to use the Ironclad Charm to block the sand and rocks, but this completely destroyed his vision.

Professor Flitwick, still in mid-air, cast another small Ironclad Charm, then leaped up, somersaulting directly over Snape's head, completing a double somersault and a 180-degree turn in mid-air.

When he lands, he will be facing Snape's back. Then, Professor Flitwick only needs to cast any spell, and he will win this round.

This move can be considered a finishing move that Professor Flitwick honed with blood in the dueling arena, and he used it to defeat countless powerful opponents.

But just as he was full of confidence and ready to cast the spell, he lost his footing and fell to the ground.

Snape reacted quickly. Although he had lost his view of what was in front of him, he still sensed a dark shadow flying overhead and immediately turned around, pointing his wand behind him.

"Exterminate your weapons! (Petrify them all!)" The two shouted the spell almost simultaneously.

Unfortunately, Snape's petrification spell flew past Flitwick's shoulder as he fell to the ground.
