I'm a wizard with a proof from Hogwarts

"boom!--"

The last 'rain' hasn't finished yet, and the next one will follow. The huge waves breaking out of the lake are like fountains, running straight into the sky.

Compared to the first explosion, many people were still awake or doing other things, so they didn't see it.This time, the explosion was louder and the interval was short. Most of the students and professors who had just rushed to the window to watch saw this wave of more shocking explosions again.

The professors rushed out of the school gate, especially Professor McGonagall. As the vice-principal, she didn't even tie her hair and ran out with her hair disheveled and her robe on.

Looking at the professors who looked equally anxious, McGonagall asked nervously: "Does anyone know what happened!?"

Several professors around him shook their heads, saying that they and others had just arrived here.

At this time, Snape and Lupine, who were late, arrived one after another, and were equally clueless about the explosion in the center of the lake.But Snape's focus was obviously not on this: "Compared to this, I think there is a friend who may need our help."

As he spoke, he sneered and pointed at the big ship that was being pushed around by the waves of the lake and looked like it was about to capsize.

Professor McGonagall was shocked and quickly called everyone to rush to help. You must know that there were many Durmstrang foreign students on the ship who came to participate in the competition!If something happened at Hogwarts, even though it was a natural disaster, they would still be involved.

Professor McGonagall lifted up the hem of her robe and ran forward, turning back to Lupine and shouting: "Remus! Go and invite Dumbledore!"

.....

At the same time, under the Black Lake.

Unlike the last wave, this time Rudy, who used [-]% of his magic power, clearly had the upper hand.

The opponent's old fish head was almost roasted. Rudy's flame magic not only shattered its water magic, but also moved all the way in front of it. If it hadn't been for the bone fork that formed a light shield at the critical moment. After blocking the attack, it's time for the grilled fish to be served.

But Rudy didn't care about this, and it was no pity. At worst, he could just have another shot.

Looking at the ferocious old fish head opposite him, Rudy raised his hand without saying anything and another fireball emitting scorching light condensed in the palm of his hand.

However, what Rudy didn't expect was that the old fish head had no fear at all.

I saw it howling "ah wow wow" without knowing what it was saying, and then it actually picked up a bone fork and slashed its own chest.

Weird blue blood gushes from the wound and is absorbed by the fork in an instant.

The next second, a dazzling blue light burst out from the fork.The bone fork kept getting bigger and bigger in the blue light, and finally turned into a big blue-gold fork!

The old fish head held up the changed fork with excited hands, and howled for a long time, and then Rudy sensed a powerful magic wave appearing on it.To be precise, a powerful magical reaction descended on it.

This operation of borrowing power from others seemed familiar to Rudy. It was essentially the same operation as his operation of connecting to the purple dimension through Morgan to obtain power.It's just that this old fish head needs to pay a corresponding price. The guy who gives it power is not the dimension itself, but a guy like an ancient god.

Good guy, Rudy never thought that he was just here to understand the situation, but he came to mess up the situation by making things difficult for the wine industry.Just fight, you said you, an old fishhead, can't beat me, but you still copy him!

Now that it's a battle involving dimensional power, it's even more forbidden to let other people from the school come over. If they get involved, things will get bigger.

To this end, Rudy took the lead in using the mirror magic - "Mirror Space"!

This is the first time Rudy has used mirror space underwater. The magical magic changes the world in the blink of an eye, dividing and twisting the entire underwater space. The lake water around him is separated, and a huge vacuum environment is formed at the bottom of the lake. The surrounding walls 'They are mirrors that flow like crystals. The lake water flows on the 'wall', as if the lake water will pour in the next second.

Without the barriers and restrictions of the venue, Rudy decided to let go and give this old fish a good head-butt. He still didn't believe it. He, Rudy, had the reputation of being the leader of Hogwarts. Come down!

With two magic rings in hand, Rudy's whole body was instantly filled with magic power and covered with magic power. Just like an out-of-control flame burning an oxygen bottle, it exploded into a big ball with a 'whoosh'.

The old fish head opposite also completed its magic at this moment. The golden and blue trident was raised high above its head. Under the strange cry, the water flow outside the mirror space actually broke through the gap in the space and converged into a winding stream in front of it. The entrenched water dragon!

This is the first time Rudy has seen on Earth. Apart from the Ancient One, there are people (oh, mermaids are also considered humans) who can transmit magic from the outside world while being isolated in the mirror space.

For this reason, Rudy specially took two more magic rings and put them on, once again increasing the supply of magic power.

"Since it's a water dragon, let's compete and see if your water dragon is stronger or my Flame Emperor is stronger!" Rudy, who was already completely ignited, didn't care about whether it was too powerful. He was so excited that he would be stronger. All the magic power retrieved from the Lord of the Rings was gathered in his hands, and then he raised his hands above his head and merged them into one.

The two balls of scorching magic power came into contact and instantly merged into a ball of flames emitting red and white light. It expanded rapidly and quickly reached a diameter of more than 10 meters!

The terrifying high temperature made the lake wall in the space evaporate, and the moment Rudy's magic was completed, the opponent's water dragon was completely formed.

Seeing that the old fish head was about to take action, Rudy did not hesitate, raised his hand and pushed forward, pushing the 'little sun' in his hand towards the opponent.

Old Fish Head: "Fah wow wow wow wow! (Arrogant Water Dragon King!)"

Rudy: "Damn old fish head, Sinai! - Great Flame Ring! Emperor Yan!!!"

The roaring Water Dragon King and the scorching little sun exploded at the first touch. The terrifying power easily tore apart the mirror space that Rudy had set up in a hurry. The aftermath of the explosion immediately spread in the black lake after breaking through the space. In the castle, The students and professors observing the situation by the black lake only saw red, white and blue lights suddenly shining from the originally dark bottom of the lake.

The next second, a terrifying shock wave suddenly occurred, and the water in the center of the lake continued to rise, as if a huge monster was pushing against the lake water and was about to rush out from below.

The moment the terrifying shock wave broke through the lake, the sky-high waves and a huge 'tsunami' slammed towards the lake.Seeing the huge roar that covered the sky and the sun, Professor McGonagall was so frightened that she turned pale. Even though she had been teaching for so many years and participated in the wizarding war, she had never seen such a battle.

If such a huge wave were to come over, the ship Durmstrang, not to mention themselves, would definitely have to rest today.

At a critical moment, a cloaked figure suddenly appeared next to Professor McGonagall.The panicked professor heard a familiar voice in her ears - "Please step back for a moment, professor."

As soon as he finished speaking, the cloaked man flipped the seals on his hands, and then several circles of golden and red magic rings appeared around his wrists.I saw her raising her hands in the air, making a lifting gesture.

Immediately afterwards, a wave of magic power rose from the ground, like an elastic wall, blocking all the water from the lake in front of them.

"Oh, my God! - God, oh!" Professor McGonagall looked at the huge wave blocked in front of her in horror. While exclaiming, she also looked at the man in the cloak in shock.

Such a natural disaster, the opponent actually blocked this monstrous force just by casting spells with both hands.This hand immediately shocked Mag, because she had seen something on Rudy's wrist when the other party cast the spell just now!

Professor McGonagall, who thought he knew the truth, did not think about the issue of 'different voices'. Instead, he happily said to the cloaked man's back: "Oh, Rudy, you came just in time. - But why are you here so late at night?" Want a cloak?"

The cloaked man was also stunned when he heard the other party's words. She did not expect that the other party would mistake her for Rudy.

But that was better. After the water returned to the lake, she turned around and waved to open the portal, and her figure disappeared in a flash by the lake.

Professor McGonagall thought he had something important to do with Peter and wanted to leave, so he didn't stop him and just watched him leave.

Who knows, not long after she left, a ball of light suddenly burst out from the center of the lake and flew slowly to the edge of the lake.

After the light ball dispersed, everyone saw that the person inside turned out to be Rudy.

Professor McGonagall was shocked: "Rudy!? - Shouldn't you...should...who was that just now!?"

Rudy was confused and couldn't understand what she was talking about. He shook off the water droplets splashed on his body, threw the thing in his hand to Snape next to Professor McGonagall and said: "Professor Snape, This is a good thing, given to you."

After saying that, he turned around and walked towards the castle without looking back.

The old bat looked at the big fork in his hand inexplicably, wondering where this thing came from.Just when he was about to throw it away, a flash of fire flashed and Fawkes arrived riding Dumbledore.

Dumbledore, who always arrived late every time, was no exception this time. When he arrived, his first thought was the casualties.After simply asking around, he smiled as if everyone was okay.

As a result, at this moment, he looked around and found Snape holding a strange thing in his hand.

Dumbledore secretly thought something bad, and quickly came to Snape and asked: "Severus, this thing is..."

Snape quickly waved his hand and explained: "This is not mine, that brat Pendragon threw it to me!"

Dumbledore looked at the trident in his hand with a headache. He didn't know what to say. After thinking for a long time, he could only ask him to give it to him first.

Holding the heavy trident, Dumbledore sighed and muttered to himself: "I don't know if that old guy is still alive."

After indicating that everyone could go back to sleep, Dumbledore came to the Black Lake, applied a layer of film-like magic to himself, and then slowly walked towards the Black Lake.

Rudy didn't know what happened next, because he only saw so much, and he didn't know what happened next, but he figured it wouldn't be a big problem.

Because...he picked up the fork, and the old fish head was fine, it was just frozen and turned into fresh food.According to Dumbledore's schedule, Rudy was not called to the principal's office until the next morning, which meant that the other party was fine.

.....

The next day, Rudy brought Hache to the auditorium for breakfast. Naturally, he received an eye roll and a rude greeting from Dumbledore.After some defense and appeal, Dumbledore sighed and said, "That's the bad thing about my old friend. He has a very bad temper and likes to get along with strangers when he meets them. The key point is that he doesn’t know English and can only speak in the language of the mermaid tribe. - If you don’t understand it, it will think that you are looking down on the mermaid tribe, and then..."

Rudy complained speechlessly: "Let me tell you, I told him nicely, but he attacked me out of nowhere without saying a word."

Then Rudy asked about the trident again: "Professor Dumbledore, you should have known that that thing was under the Black Lake, right?"

Dumbledore nodded and said, "Yes. - It was a magical weapon created by the Big Three. Its function was to quell the undercurrent under the Black Lake and the riots of magical creatures."

"The space in the Black Lake is far wider and larger than you imagine, and there are even dragons living in it. Various ethnic groups have been mixed under the Black Lake for thousands of years. The reason why they can coexist peacefully until today is all due to this root The trident calmed the storm under the lake."

At this time, Rudy suddenly changed the topic and asked: "So, the test question for the second project is indeed under the Black Lake?"

Dumbledore didn't react at all. He nodded subconsciously and replied: "Yes, of course. - Oh. Damn it."

"Look Rudy, I'm not telling you anything."

Seeing the old fox reveal his secret, Rudy smiled happily and said, "Of course, Professor." Without saying a word, he stood up and left the dining table and walked towards the Gryffindor table.

On this side, Harry and the others were having a headache discussing how to deal with the second game.

According to their current guess, the venue is in the Black Lake.Apart from the things that were taken away, the most important thing now is - how should he get into the water!In other words, what should Harry do if he needs to stay under the Black Lake for a long time?

At first, Harry's idea was to try to become an Animagus like Sirius.

But Hermione directly rejected this method, because not to mention that the Animagus form is difficult to change, the most important thing is that it is uncontrollable, and it is very difficult to practice it, and the conditions that need to be met are also very complicated. It's almost impossible to succeed at their current level.

Later, Ron suggested simply using magic to drain the lake.Of course, this opinion received a pair of blank stares.

In the end, the three of them spent the whole night looking for a way, and perfectly missed Rudy's Battle of the Black Lake.

Looking at the unhappy three people on the Gryffindor table, Rudy leaned over and asked, "So, do you need any help?"
