The merfolk leader didn't seem to understand what Jon meant.

"We can't help!" it said in a hoarse voice, touching its long green beard and taking a few steps back......

Watching Jon raise his wand, the merfolk thought Jon was trying to use magic to untie the ropes from the hostages he was trying to save.

For magical creatures like merfolk, they are still quite intimidated by wands...... Because they are born with no knowledge of magic.

"Petrificus Totalus!"

Jon raised his wand and aimed it at the merfolk leader, shouting without hesitation, several blisters popping out of his mouth.

Then a column of boiling water struck the unsuspecting merfolk leader...... Then, after a few seconds, its arms snapped to its sides, its tail straight, and its whole body stiffened, and it swayed in place a few times before falling to the mermaid's back with a thud, looking as hard as a plank.

The rest of the merfolk haven't reacted yet—

The Iron-Eating Beast Patronus in the blister suddenly changed his expression and let out a scream: "Ahhh......h

The Patronus howled angrily, using almost all of its strength, and the color of its body became a little languishing. Its cry resounded through the bubbles, through the lake, and through the merfolk village.

Almost all of the merfolk lowered their heads and covered their ears, and the expressions on their faces became painful.

This kind of soul oppression from high-level magical beasts is unbearable for them.

......

Taking advantage of the mermaids' lack of reaction, Jon used a "swelling spell" to accurately hit the egg of the fiery gray snake floating in the lake beside him.

The fiery red egg, which was wrapped in ice, began to swell rapidly......

At first it was the size of a football, then it was about the height of a person, and after a few seconds, it was almost the size of a small mountain.

Moreover, without the traction of the Patronus, the eggs of the Fire Ash Serpent began to sink rapidly...... Below it is the mermaids' village.

At the same time, cracks began to appear on the ice that wrapped the eggs...... Through the ice, the eggs of the entire Fire Ash Snake were dazzlingly red, emitting a blazing light!

Some well-informed merfolk have already recognized what this is.

The Fire Grey Serpent is essentially a strange creature created by an unextinguished demonic fire, and their mission is to find a dark corner to lay eggs and then disappear in a matter of minutes.

Once the eggs of the Grey Snake get out of control, especially if they are released with a "Expansion Spell", they will generate terrifying heat......

Any creature that lives in the ocean is afraid of heat, and mermaids are no exception.

Their first thought was to flee when they saw the "big fireball" about to explode, but when they thought that their village was below and there was no way out, many of the merfolk couldn't help but yelling at the webbed wizard and the strange bear.

Then, in all directions, hundreds of merfolk surrounded the eggs of the hill-sized fiery snake, and held it up with harpoons from the bottom up to prevent it from falling completely into the merfolk village below.

The adult merfolk were able to withstand the heat from the eggs of the Grey Snake, but if they were allowed to fall into the village below, the merfolk calves would suffer a lot of burns.

......

Jon certainly wasn't idle.

While the merfolk were all attracted away by the eggs of the fiery snake, he raised his wand towards the four girls:

"Incarcerous?? ！”

Jon shot a thick rope from the tip of his wand, tying the four girls together.

Then he aimed his wand at the boulder behind them:

"Broken bones?? （Reducto）！”

The mermaid's tail is shattered by him, and the four girls float in the water, and Jon grabs the thick rope he has just conjured.

All four of them looked to be sleeping deeply, their heads slung limply over their shoulders, and a string of thin blisters kept coming out of their mouths...... Even such a big movement didn't wake them up.

While tugging at the rope, Jon took the opportunity to use his flippers to kick the water hard and swim to the surface......

At the same time, he also conjured up a large blister around the four girls......

Under the effect of buoyancy, it didn't seem to be much trouble for him to pull the four people upstream.

Jon didn't control the direction, he just wanted to float to the surface of the water now!

At the same time, the Patronus also burrowed under Gabrielle Delacour's ass and pushed them up......

Heart-rending roars rang out all around.

The merfolk seem to have taken the eggs of the fiery grey snake out of the danger zone.

Their fierce gaze was already on Jon.

About a hundred merfolk with harpoons swam in Jon's direction.

"Ahh......h

This time, though, the effect is much smaller.

It only stopped the merfolk a little, and they continued to surround them from all sides.

......

At this moment, on the shores of Lake Hogsmeade.

Madame Maxim grabbed Fleur Delacour and comforted her.

Fleur was completely hysterical, and she struggled desperately to throw herself into the water. She had scars on her face and arms, one on the left and one on the right, and her robe was torn......

"Gabrielle, Gabrielle......" Fleur shouted in vain, "I have to save her......"

But it was obviously not easy to break free from Madame Maxim's arms.

"Miss Delacour, you've been eliminated and are not allowed to enter the lake again!" Percy Weasley stopped in front of her, reminding her with a blank face.

Five minutes earlier, Fleur had been attacked underwater by a group of Grindellows, and the poor girl had stunned one and was caught from behind by the other two...... Fleur was choked by two Grindillo fingers and had blisters on her head......

If Dumbledore hadn't saved her, I'm afraid that in Grindellow's habits, there would have been a mutilated female corpse floating on Lake Hogsmeade in a few hours.

But in the same way, she also lost the right to participate in the competition.

Suddenly, in the middle of Hogsmeade, tons of bubbles bubbled.

At the same time, it seems that a small vortex has been created...... It was as if something was floating up.

"What's going on?" both the spectators and the referees were fascinated by the strangeness on the water.

"Is it a giant squid?" exclaimed a first-grader excitedly, "don't they usually like to be in the water?"

Their eyes were fixed on the strange place on the water.

Only Dumbledore was the exception.

Albus Dumbledore's gaze turned in the direction of the castle.

His eyes were full of surprise.
