Chapter 309 The Horror of the Black Lake

cold!

Even though he had taken the enhanced warming potion specially prepared by Benjamin, and even though he had put on a professional diving suit, the huge temperature difference still made Mike shiver the moment he entered the black lake.

Mike quickly took out his wand and silently cast a warming spell on himself before feeling much better.

Only then did Mike have the energy to observe the surrounding scene.

The transparent film formed by the Bubble Charm not only provides Mike with the oxygen he needs to breathe, but also acts as a waterproof eye mask, allowing Mike to see more clearly.

At this moment, Mike's location was not far from the lake. The light from outside passed through the lake with difficulty, illuminating Mike's surroundings into a hazy scene.

Harry and the others had disappeared a long time ago, they must have dived early.

Thinking of this, Mike shook his head, so what if he takes the first step? This small advantage is nothing at all.

'Show me the way'

A vague sound came from the transparent film covering Mike's head, and then the blackthorn wand in Mike's hand floated.

It rotated rapidly in the water, and finally pointed diagonally to the deep water below.

Mike laughed.

The Guiding Spell is also called the North Spell, because its effect is that after casting the spell, the tip of the staff will point to the north, and it is often used to identify directions.

But after being transformed by Mike, the role of this guiding spell also changed from pointing north to pointing to Penelo.

To be precise, it refers to the special pendant on Penelo.

The pendant can continuously emit a unique magic wave to the surroundings, and the modified guiding spell can accurately track this wave within a certain distance, allowing Mike to quickly find Penello.

After confirming the position, Mike withdrew his wand and began to dive with his flippers.

This was not a good experience. At this moment, he was swimming around in a hazy and strange scenery, with silence in his ears, and the only source of light was the faint skylight above his head.

Thanks to this faint skylight, he could still see some things for the time being, but the visual range was not large, only about ten feet in radius.

Therefore, every time he glides in the water, a new scenery will emerge from the darkness in front: a jungle of undulating and tangled black water plants, a wide and flat stretch of sand scattered with sparkling pebbles, etc. .

He swam deeper and deeper in the direction pointed by the wand, and the visible range around him became smaller and smaller, which forced him to open his eyes wide and carefully observe the surrounding environment.

Suddenly, Mike's pupils shrank suddenly.

In the darkness in front of him, there seemed to be some huge object slowly moving towards him.

Mike could guarantee that it was definitely not a human being. No human being could grow that big.

When normal people encounter this kind of situation, they will inevitably feel fear in their hearts. This is the fear of ancient giant beasts engraved in human DNA.

But Mike is different. Since entering Hogwarts, he has not forgotten that he is a wizard.

So, after confirming that the thing slowly floating toward him was not Harry and the others, Mike raised his wand without hesitation.

‘Thunderbolt explosion! ’

A muffled sound came out from the transparent cover again, and then a white light drew a clearly visible trace in the dark water and flew towards the unknown object.

"boom!"

A loud noise came from the loud noise mixed with some vague screams, and the huge unknown object was instantly blown to pieces.

A powerful current swept through, turning the lake water into a turbid mess, and Mike's field of vision narrowed again.

At this moment, Mike no longer hesitated and directly activated his magic perception. Although the magic perception was obviously suppressed underwater, it was still better than seeing nothing at all.

After swimming forward again for nearly ten minutes along the muddy lake bottom, a large group of half-human, half-fish figures suddenly appeared in Mike's magic perception.

They moved extremely fast and were near Mike in an instant, as if they were afraid that Mike would escape.

However, Mike stayed where he was and remained motionless.

He had already guessed the identity of these creatures, merfolk.

This kind of creature living at the bottom of Hogwarts Lake would not attack the students of Hogwarts at all, so he didn't need to worry at all.

The mermaids slowed down and slowly swam in front of Mike, and now Mike finally saw these legendary mermaids.

Their beards and hair were all green, their skin was gray, their upper bodies were full of linear muscles, and their lower bodies were fish bodies covered with scales.

It can be seen that they are quite intelligent and have even learned to tame animals, because they are still holding ropes in their hands, and at the other end of the rope is tied a Grindylow - a kind of creature with horns on its head. A water monster that likes to attack people who fall into the water.

To be honest, Mike was a little disappointed, because these fishmen were exactly as written in the book. Not only were they not beautiful, their faces even looked a bit ferocious.

And when Mike was observing these mermaids, those mermaids were also observing Mike.

A tall fishman with a mouth full of shark teeth carefully looked at Mike, who was dressed in a black frogman costume, as if he was trying to determine whether the strange creature in front of him was a human.

Mike was about to reveal his identity and ask these mermaids to let them go, when he saw the Gundam mermaid pointing at the short golden hair on his head and making a squeaking noise as if he had discovered something extraordinary.

When the other mermaids heard this, they all showed ferocious smiles. Then they released the ropes they were holding, pointed at Mike and let out a series of strange screams. The next moment, the group of Grindylows It rushed towards Mike like a hunting dog.

Seeing this, Mike's expression darkened and he took out his wand again.

Although he didn't know what was wrong with the brains of these mermaids that they dared to attack him, Mike was not afraid of them.

‘Serial Thunderbolt Explosion! ’

Wave after wave of violent explosions appeared in front of Mike. The numerous Grindylows had no ability to resist such explosions. They were either blown into pieces or knocked unconscious by the shaking water.

The mermaids in the distance opened their mouths and looked at the astonishing scene in front of them in amazement.

"This is different from what I said at the beginning! That human lied to us! That blond-haired guy is not a human cub at all! There is no way a human cub has such terrifying power! (Mermaid language)"

"(Mermaid language) It's too late to say this now! That guy has already pointed his wand at us!"

As soon as these words came out, the remaining mermaids immediately became nervous.

They are all young mermaids who have lived in the Black Lake since childhood.

Although their elders tell them about the power of wizards every day, they have never seen the power of wizards with their own eyes and always think that the group of humans living in the castle are nothing more than that.

In addition, the mermaids have been thriving in the Black Lake all year round, which has gradually depleted the resources and territory in the Black Lake.

So when the human in black robes found them and said that he would exchange a larger lake for the life of the blond human, the group of mermaids agreed almost immediately.

At this moment, they finally saw the power of the wizard, and Mike's amazing power scared them out of their wits.

They looked nervously at Mike, who had pointed his wand at them in the distance, and had the urge to turn around and run away.

But where can they go?

Judging from the continuous explosions just now, Mike's attack range is astonishingly large, and they can't escape at all.

However, Mike on the opposite side had no intention of continuing to use the large blasting spell.

He just wanted to catch a few alive so that he could torture them to find out why they wanted to do it themselves.

It's a pity that the mermaids opposite don't think so.

They chattered again for a while, and then the mermaid in the opposing team who was carrying a huge horn took off the horn with a serious face, put it to his mouth and started playing vigorously.

A low sound, like the roar of an ancient behemoth, came from the huge horn, and gradually floated into the distance led by the water flow.

Of course, the look of fear on the faces of the mermaids who had finished blowing the horns was gone, replaced by extremely arrogant laughter and roars, as if they had already secured victory.

Listening to the horn sound, Mike suddenly had a bad feeling.

The next moment, Mike, who was still using his magic perception, discovered that a huge creature was swimming quickly from a distance. Judging from the rough outline, it seemed to be a huge octopus!

The octopus from the black lake!

Mike instantly had the urge to curse.

If he faced a monster of this size on the ground, Mike would still be sure to escape unscathed, and even have a chance to kill the opponent.

But this was underwater, his mobility was suppressed to the extreme, and the fire spell couldn't be used, which made him no match for the opponent at all.

Gritting his teeth, Mike waved the wand in his hand repeatedly, and the powerful magic turned into golden chains. One end was caught in Mike's hand, and the other end was automatically trapped on some of the surviving Grindylow water monsters.

These Grindylows had obviously sensed the arrival of the giant octopus, and were now swimming in the direction of their master in terror.

With their help, Mike's speed increased several steps, and the mermaids who were still in high spirits froze their smiles upon seeing this.

"(Mermaid language) Run quickly!"

I don't know who shouted this, and the mermaids immediately fled.

It's a pity, how can a man outrun a hunting dog?

In the same way, these mermaids could not swim these Grindylows who were domesticated as hunting dogs. In just a short moment, the group of Grindylows led Mike to catch up with several fleeing mermaids.

The faces of the mermaids darkened, and they raised the tridents in their hands, intending to fight Mike to the death, but the next moment Mike had already raised his wand.

"The Divine Edge is Shadowless!"

As Mike roared, all of the mermaids were cut in half, and large amounts of green blood spurted out.

Mike kept controlling the group of Grindylows to continue swimming in the direction pointed by the wand at the beginning. As long as the Grindylows deviated from the direction, Mike would beat them hard with the golden chain.

Time passed little by little, and with the help of the Grindylows, Mike had heard the familiar and beautiful singing, and the outline of a village vaguely appeared in front of him.

But at this moment, a dull roar also sounded from behind him.

Mike knew that this must be the damn octopus catching up.

Turning around, he saw that, sure enough, a huge black shadow had enveloped him, and a huge tentacle stretched out from the black shadow, grabbing at Mike.

"The Divine Edge is Shadowless!"

The movement of the huge tentacle suddenly suffocated, and then a blood line suddenly appeared on the tentacle.

The blood line expanded rapidly, and large streams of blue blood spurted out from it. In the end, the entire huge tentacle was broken.

"Roar!"

The terrifying roar came again, but this time there was obviously some anger in the roar.

Without any urging from Mike, the Grindylows swam desperately towards the village.

Mike, on the other hand, was looking behind him intently, resisting the monotonous tentacle attack of the big octopus.

This attack mode is really monotonous. Mike swings his wand repeatedly, but any tentacles drawn by the big octopus will be chopped off by Mike's Shadowless Curse.

The surrounding water has been completely dyed blue by the octopus's blood. The big octopus began to twist its body crazily under the pain, and under its influence, the entire black lake became turbulent.

The mermaids in the mermaid village naturally noticed such a big movement. A large number of mermaids holding tridents swam out of the village. At the same time, a horn sound with a significantly different tone from before also sounded in the village.

Hearing the sound of the horn, the giant octopus was suddenly suffocated, but then it continued to rush towards the village.

Today, it must kill the blond boy who hurt it!

The group of mermaids holding tridents were stunned when they saw that the horn sound had no effect. When they reacted, they gritted their teeth and rushed towards the giant octopus.

Behind them is their home, and the giant octopus must not be allowed to rush in and cause damage!

When Mike saw that this group of mermaids not only had no intention of attacking him, but even took the initiative to help him stop the big octopus, he felt happy. He took back his wand and quickly urged Grindylow to enter the village.

From a human perspective, this is an extremely strange village.

There are grottoes everywhere in the village, as well as some strangely shaped boulders. These stones seem to be the homes of the mermaids, because there is this door on the stone!

In the center of the village is an open space. A large number of mermaids are gathering in the open space at the moment, looking worriedly at the soldiers who are fighting the giant octopus.

Behind them stood a rough mermaid statue, with four people tied tightly to its tail.

Ron was tied between Hermione and Penello, and there was also a little girl who was at most eight years old. Her cloud-like silver hair made Mike convinced that she was Fleur's sister.

The four of them all seemed to be sleeping deeply, their heads were hung feebly on their shoulders, and strings of thin blisters kept popping out of their mouths.

Beside these four people was a half-human, half-shark monster.

That's Krum!

At this moment, he was tugging and biting at the rope around Hermione. The problem was that Krum's shark teeth had a very weird structure. It would be awkward for him to get up on anything smaller than a dolphin. It would be awkward for him to bite off something as delicate as the rope. The job clearly wasn't for him.

Mike flicked his wand, and the ropes binding the four people were all broken.

Krum was stunned for a moment, then gave Mike a thankful look, grabbed Hermione's waist and started to rise to the water.

Mike yelled: "Stop! Get the others up too, it's no longer safe here!"

Krum stopped. Of course, it wasn't Mike's words that made him stop. Neither of them could hear what the other was saying in the water.

What really stopped him was the wand Mac pointed at him and the cold look in his eyes.

Krum believed that if he dared to swim forward again, Mike would attack him without hesitation.

After swimming back tremblingly, Krim felt that he had been completely humiliated.

Mike didn't care what he thought. He tied all four of them to Krum, and then tied Krum with magic ropes like he had tied Grindylow before.

"Let's go!"

Mike shook the rope, and Klum understood. He gritted his teeth and dragged the four people to swim towards the water with difficulty.

Heaving a sigh of relief, Mike looked towards the direction of Mermaid Village again before leaving.

The mermaid soldiers still failed to resist the giant octopus. At this moment, the monster had rushed into the mermaid village and was wreaking havoc in the village.

Houses collapsed, screams continued, and mermaids were everywhere.

Mike held a moment of silence for these mermaids, and continued to be led by Klum towards the water.
