"If you're looking for an underwater trip, gill grass is undoubtedly the best choice for you.

It will help you swim freely in deep water, unlike the blister spell, which can easily be crushed by the pressure of the water once you dive too deep.

It's also not like some botched Transfiguration techniques that make you extremely miserable while swimming.

Of course, if your Animagus is a fish, you don't need to worry about that!"

This is a detailed description of the gill plant by Elladora Katerridge, author of The Wonders of the Mediterranean Aquatic Plants and Their Properties.

Jon was in his own hands, feeling the pleasure that the cheek grass brought him.

In particular, he has an egg of a fiery snake to raise the temperature of the water, and a Patronus to lead the way.

Of course, Jon hadn't forgotten to reapply a freeze charm to the Grey Serpent's egg every few minutes, otherwise he might have been burned if it burned in its entirety.

He didn't forget that he was here for the second event, not for fun.

......

Jon swam in the dark waters of the lake, only the light of the Patronus could illuminate the path, and there was silence in his ears, and small fish swam swiftly past him.

The Patronus didn't make any sound, it just stared forward with a bubble in it, as it surveyed its surroundings.

"Whew!" Suddenly, the Patronus's gaze glared at Jon and let out a warning cry.

Jon understood and quickly dived underwater with the bubbles containing the Patronus.

They had barely descended when Jon seemed to see a large creature slowly swimming overhead.

An almost terrifying behemoth, Jon estimates he's about the size of a Ukrainian iron belly!

The giant squid of Hogsmeade Lake, the creatures at the top of the lake's food chain...... Under this water, they may be even more terrible than the Ukrainian iron belly!

Jon struggled not to make any sound, hiding in the aquatic weeds at the bottom of the lake.

Fortunately, the giant squid didn't seem to be a good diver and its eyesight was mediocre, and after only a few minutes, it swam away.

Otherwise, Jon is afraid that this trip will be explained here.

......

Swam some distance further.

In front of it was a field of turquoise aquatic grass, two feet deep, which looked like a very dense lawn from a distance.

"Whew!" the Patronus sounded again, watching the pile of weeds warily.

Jon nodded, and he stretched out his wand and pointed it forward for a moment, while spitting bubbles out of his mouth:

"Diffindo!"

Several aquatic plants were torn off in an instant, revealing several hideous faces hidden inside.

A monster with horns, pale green, and looks like a devil in the water......

It's Grindy Lowe!

Grindillo is a magical creature that lives extensively in lakes throughout Britain and Ireland. They feed on small fish, but also attack Muggles and wizards, and Grindillo's long fingers are their main weapon.

At the same time, they are also their weaknesses, as Professor Remus Lupin detailed in the second-year Dark Magic Defense class. "These fingers, despite their strength when they grasp things, can easily break. ”

A couple of Grindillo swooped down in Jon's direction......

"Relashio!" Jon shouted unhurriedly, a blister coming out of his mouth......

This is the most reliable spell against Grindy Lowe.

A jet of boiling water struck a Grindylow, turning its pale green paws red.

"Relashio!"

"Relashio!"

Having repelled three Grindillos in a row, the Patronus no longer makes a vigilant sound.

Jon breathed a sigh of relief and made his way through the weeds.

There was almost complete darkness around him, and he felt only the silence pressing down on his eardrums...... Jon knew he had reached the bottom of the lake.

Then it shouldn't be far from the mermaid village.

......

The Patronus seemed to have made a new discovery, and he quickly drifted in one direction.

Jon hurriedly followed the Patronus, knowing that it had found the location of the merfolk village.

They swam fast and time passed quickly...... Jon looked at his watch, fifteen minutes had passed.

Suddenly, Jon heard a voice—

"We snatched your most beloved baby.

You've only got an hour to ......."

The merfolk's singing was clearly visible, much to Jon's chagrin.

"After an hour, there is no hope ......"

Enduring the noise of merfolk singing, after a few minutes, Jon found himself beneath his feet with a lot of rough sand and gravel houses, covered with some algae.

In front of many small houses, there are several human-like fish-tailed creatures.

The merfolk had an unsightly iron-gray skin, and their dark green hair was long, messy, seaweed-like.

Their eyes are yellow, their mutilated teeth are yellow, and they wear pebbles strung with thick rope around their necks.

In short, both male and female mermaids are quite ugly in appearance...... Sure enough, fairy tales are all lies.

......

There are more and more houses made of sand and gravel, and it is clear that this is a mermaid village.

Many ugly merfolk emerged from it, looking curiously at Jon, pointing at his webbed hands and gill sacs.

It's like a group of city people watching a hillbilly.

Soon, Jon was in the middle of the merfolk village.

A very tall statue appeared in front of him.

It is a large mermaid carved from a boulder, although it is relatively rough.

On the tail of the mermaid statue, four people are firmly tied.

All four of them looked like they were sleeping deeply, their heads leaning limply over their shoulders, and a string of thin blisters popping out of their mouths.

Four girls, all tightly tied with ropes.

Astoria seemed to be lying on Hermione's lap, with Cho Chang at her feet, and the eight or nine-year-old silver-haired girl on the other side must be Fleur's sister Gabrielle.

Jon struggled to swim that way, but the merfolk around him didn't stop him.

It looks like that's the end of the ordeal.

Next to the four girls, there was also a mermaid who was slightly taller than the average mermaid.

With a crown made of shells on its head and a short necklace made of shark teeth around its neck, it looked like the leader of the merfolk.

"You can only take one of them......" the merfolk leader made a hoarse voice as he gestured, "...... You're the fastest to get here!"

The little iron-eating beast inadvertently took a few steps downward, and the merfolk did not stop it either, and several female merfolk even showed it motherly eyes.

"I'm sorry, I didn't have to choose ......," Jon shrugged as he raised his wand.

"But now, I want them all!"
