Krum bore the brunt.

He flew out almost as soon as Bagman gave the order.

With the swing of his wand.

His upper body began to twist and deform, and eventually turned himself into a half-human, half-shark monster the moment he jumped into the water.

"Oh! Human Transformation! Krum used a very bold method! This is really dangerous! You must know that if you are not careful with the Human Transformation, you will not be able to change back..."

Bagman's hasty explanation caused a lot of exclamations in the stands.

Cedric and Fleur were equally slow in their movements.

They use the [Head Bubble Curse].

This magic can create a large bubble around the head, allowing people to get enough oxygen to breathe underwater or when the surrounding air is polluted.

As for John, Michelle and Harry.

They had eaten a large ball of gillweed before setting off.

These plants are more miraculous than bubble-head spells and can directly give humans gills and webbed fingers and toes within a period of time.

Touching the two narrow cracks under the ears, John and Michelle looked at each other and smiled, then got into the water.

The Black Lake is extremely cold in winter.

Although they have cold-proof swimsuits that can block the cold brought by the external water flow, the presence of fish gills requires them to continuously inhale lake water.

The lake water carried a coolness, constantly pouring in from their mouths, and then gushing out from the gills. While bringing oxygen to John, the coolness also gave John a knife-like discomfort.

It took a full five or six minutes for John, Michelle and Harry to completely move their bodies and adapt to the underwater environment.

At this time, the lake water no longer felt cold and biting to John.

On the contrary, he felt very cool and comfortable, and his body became very light.

"John, we have wasted too much time, we must go downstream quickly!"

Using his webbed hands and feet to paddle through the water, Harry said anxiously.

His voice became very strange underwater, and there was a sense of urgency in it.

But this can't be blamed on him.

After all, while they were adapting to the water temperature, Krum and others had disappeared.

But upon hearing this, John smiled and said:

"Don't worry, we will catch up with them. But before that, we still need to wait for a few friends."

Harry looked confused.

But before he could continue to ask questions, he saw several mermaids swimming under the three of them.

They are not as beautiful as the legendary mermaids, but in fact, they are not ugly at all.

Except for their iron-grey skin, dark green hair, and fish tails on their lower bodies, they are almost the same as ordinary girls in Hogwarts.

The only thing that made Harry feel uneasy was that these mermaids were followed by several Grindylows.

Professor Lupine once introduced this little underwater devil with horns to his students.

They often attack humans.

However, at this moment, they were following the mermaids obediently, just like pet dogs.

"Yiyayi!~Yiyayi!~"

The mermaids gathered around John and sang happily.

From time to time, he would come and shake hands with John, and then look shy.

"The Black Lake Mermaid is Slytherin's neighbor. When we have free time, we often talk through the glass or play some small games." John explained with a smile, "So this time, I commissioned these lovely

The young lady is here to lead the way for us."

"As expected of you, John!"

Harry sighed with admiration on his face.

He really admired John for being able to come up with such a method.

At this time, Michelle had already become involved with the mermaids and was holding hands and singing songs.

It can be seen that the mermaids also like her very much.

"Okay, now that everyone is here, let's set off quickly."

Following John's order, the three mermaids stopped playing with Michelle.

Each of them took a hand of John, Michelle and Harry, and started swimming in the black lake in cooperation with the Grindylows.

This speed is much faster than John and others swimming by themselves.

After a while, a strange village appeared in front of John and others.

The village was entirely made up of rough stone dwellings, speckled with algae. From time to time, mermaids would look at them curiously through the windows of the dwellings.

The deeper you travel into the village, the denser the number of stone dwellings becomes.

Some dwellings even have their own gardens.

In a small square in the center of the village, a huge mermaid statue faced John and others.

Six people were tightly tied to the tail of the mermaid stone statue.

Draco and Ron were tied between Hermione and Cho Chang, with Alice and a little girl who was at most eight years old on the outside.

Just by looking at the little girl's misty silver hair, you can tell that this is Fleur's sister Gabrielle.

They all seemed to be sleeping deeply, with their heads hanging limply on their shoulders, and a string of thin blisters popping out of their mouths.

At the same time, more and more mermaids were swimming with John and others.

Most of them were young men and women, and they should be familiar with John.

Because as soon as they appeared, they would rush to John's side and rush to shake John's hand.

Seeing this, Harry felt even more emotional.

It's great to have John here!

Without John's help, he would have drowned in the lake long ago.

Just when Harry was thinking this, a dull but huge roar suddenly sounded.

Harry looked towards the source of the sound in horror and saw a huge black shadow slowly approaching in front of them.

"Don't worry, John, that giant squid is also our friend, it won't hurt us."

A mermaid said easily.

But John's expression became serious.

Because in his magic perception, the magic aura of the giant squid is much more ferocious than usual!

Seeing this, the mermaid chuckled and swam towards the giant squid, as if he wanted to prove his previous statement.

But she had just gotten close to the giant squid, and before John could stop her, a huge tentacle swung out from the darkness and whipped the mermaid away!

"Prepare to meet the enemy!"

John shouted and drew his wand.

Michelle and Harry quickly followed suit.

The mermaids were not as calm as John and the others who had been prepared.

The sudden attack of the giant squid frightened them all, and they all froze on the spot.

"Woo——"

The terrifying and deep roar sounded again.

The giant squid finally sprang out of the darkness, revealing its full appearance to everyone.

At the same time, it also raised a tentacle and struck hard at John and others.

People at Hogwarts are actually no strangers to giant squids.

You can often see its shadow swimming in the Black Lake.

On sunny days, it will even swim to the shallows and let the students at Hogwarts tickle its tentacles.

The giant squid actually looked quite cute back then.

But now, when the terrifyingly huge size of the giant squid was revealed in front of him and launched an attack, the instinctive fear of the deep sea and giant monsters that humans have in Harry's heart broke out!

At this moment, Harry felt that his heartbeat was about to stop.

"Run quickly——"

John's roar woke Harry up from his fear.

I saw John, holding his wand high, and quickly recited the spell:

"The Divine Edge is Shadowless!"

"laugh--"

The blade that was supposed to be invisible revealed its original appearance under the influence of the current.

It cut a white wave underwater at an unimaginable speed, and stamped it hard on the huge tentacles that were coming.

However, John's powerful slash, which was powerful enough to cut through the fire dragon's scales, did not completely cut off the tentacle.

When the two came into contact, only nearly one-third of the huge tentacles were cut off!

Fortunately, the powerful kinetic energy of [Shen Feng Wu Ying] still pushed back the tentacles!
