The next day, at half past seven in the morning, February 24, Jon Hart opened his eyes.

Getting out of bed, he checked his wand again and put a waterproof wand on it.

At the same time, he found the few things he needed to take with him.

Once confirmed, he slipped them into his most private pocket and walked out of the Hufflepuff common room.

The Hufflepuff "cheerleaders" were waiting for him, and after the baptism of the first project, they were now considered well-trained.

"Come on, Jon!"

"Trust you, you're going to win!"

"Long live Hufflepuff!"

Surrounded by Hufflepuff cheerleaders, Jon made his way to the dining room to grab a bite to eat, and after filling his stomach, he walked through two oak gates to the site of his second project, Lake Hogsmeade.

But someone stopped him.

Daphne Greengrass was so crazy that she didn't even notice that she had crashed into Zachares Smith and Eloise Meadgan.

She ran straight to Jon.

"You must save her!" Daphne's trembling voice was tinged with a hint of crying, as she grabbed Jon's arm.

"What's going on?" said Zachares, who had been knocked away, with some dissatisfaction.

"They've taken Astoria away!" Daphne cried, "she's locked up at the bottom of the lake, and she's only been protecting her magic for an hour...... You need to save her...... If you can't get her out, she's going to die......"

There was a sudden chatter around him.

Astoria was part of the second project, which was no surprise to Jon. But he was sure that even if he didn't save them, Dumbledore would protect them unscathed.

It's just that Daphne, who was frightened by the news, didn't realize it for a while.

"I will. Jon nodded.

"You've got to get her out......" Daphne looked at Jon earnestly, completely devoid of her haughtiness.

"Definitely!" Jon said calmly.

Daphne let go of his hand.

......

The seats that surrounded the dragon farm last November are now lined up on the other side of the lake, and they are already full, and their reflections are reflected in the lake below.

Five referees were waiting for them by the lake, with Barty Crouch turned into Percy Weasley.

"Looks like the warriors are all here?" Ludo Bagman said kindly.

Victor Krum and Harry Potter had already arrived at the referee's table, a table covered with a golden tablecloth, and Fleur Delacour and Jon had arrived almost on their feet.

"Then let's get started. Dumbledore smiled and said, "You all know the rules of the game?"

The four of them nodded in unison.

"Your most important people have been taken by the merfolk and imprisoned near their villages...... You must overcome many obstacles to defeat the enemies in the water and rescue them...... There's only an hour!"

Dumbledore had already repeated the rules, his tone rather serious.

"That's good!" Ludo Bagman clapped his hands quickly: "Get ready, start now!"

All four warriors came to the lake.

Jon took off his robe, revealing his swim trunks underneath, and wiped himself with the lake water.

Very cold lake water...... It is very uncomfortable to rub on the body.

Fleur Delacour cast a complex-looking spell on herself, and then a large bubble enveloped her, sending her all the way to the surface.

Krum used a transfiguration spell on himself, and his head immediately turned into a hideous-looking shark's head, but his spell seemed to be only half successful, and the other half of his body was still humanoid.

Jon pulled out a handful of cheek herbs and shoved them into his mouth.

The taste of the gill is quite terrible, like chewing raw spider legs, dry.

For a moment, something seemed to weigh down his mouth and nose, and his lungs were empty, and there was a sharp pain on the sides of his neck—

Fortunately, this was not the first time Jon had taken the gill grass, and he was mentally prepared and didn't make much of a fuss.

Almost at the same time, his fingers and toes began to join together to form a soft, webbed structure, and his feet looked like duck webs.

"Go!" shouted as Ludo Bagman shouted Jon into the water.

Harry Potter on the other side only started taking gill sac grass at this time.

......

Jon took a hard breath of the lake water, then felt the water flow smoothly through his gills, carrying oxygen into his brain.

All the best...... The resistance in the water seems to have been reduced a lot, and my body has become much lighter when I swim.

Jon then pulled out a small ball of ice and pointed at it with his wand.

A crack appeared in the thick ice on the surface of the ball...... Heat escapes from it.

The eggs of the Fire Ash Snake, which are excellent heat sources in their own right, can emit quite terrifying heat...... And if the ice is well frozen, the heat they emit can be controlled.

Jon felt that the water around him had become a little warmer and more comfortable.

Now, everything is ready, all you need to do is find the merfolk's village.

The hint in the golden egg can be clear: "Look for us, where our voice sounds!"

So all you need to do is find the merfolk's song to find them.

However, with the reception frequency of the human ear, it is difficult to hear the mermaid's song, and Jon raised his wand and shouted softly:

"Expecto Patronum!"

There was just a string of blisters in his mouth, but the spell was still released.

With a flash of silver light, Jon's Iron-Eater Patronus appeared in front of him, looking at the strange sight around him with some surprise.

A blister spell quickly enveloped the ironeater, saving him from having to struggle in the water.

"Can you hear me?" Jon asked softly, "the merfolk's song?"

"Whew!" the Patronus let out a cheerful cry and nodded.

"Alright, you lead the way!" Jon conjured a line so that the Grey Serpent's egg could follow behind the ironeater's blister.

The Patronus in the blisters opens the way ahead.

Then there's the egg of the Grey Serpent, which radiates heat little by little, while banishing the magical animals from the surrounding water.

Finally, Jon followed them and paddled forward.

His eyes could be wide open, no swimming goggles needed, and warm water flowed around him, as if he were on vacation in a hot spring.

This peculiar team swam to the bottom of the lake.
