Chapter 309: The Terror of the Black Lake

Cold!

Although he had taken the enhanced warming potion specially prepared by Benjamin and 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 he felt much better.

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

The transparent film formed by the bubble head spell not only provided Mike with the oxygen he needed to breathe, but also played the role of a waterproof eye mask, allowing Mike to see more clearly.

At this moment, Mike was not far from the lake surface. The light outside passed through the lake surface with difficulty, illuminating the area around Mike.

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

Thinking of this, Mike shook his head. What's wrong with going one step ahead? This little advantage is nothing at all.

"Show me the way" a

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

It spun rapidly in the water, and finally pointed obliquely to the deep water below.

Mike smiled.

The Guiding Charm, also known as the North Compass Charm, is often used to identify directions because its effect is that the tip of the wand will point to the north after casting the spell.

But after being modified by Mike, the function of the Guiding Charm has changed from pointing to the north to pointing to Penelo.

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

The pendant can continuously emit a unique magical fluctuation to the surroundings, and the modified Guiding Charm can accurately track this fluctuation within a certain distance, so that Mike can quickly find Penelo.

After confirming the location, Mike retracted the magic wand and began to dive with fins.

This was not a very good experience. At this moment, he was swimming in a hazy and strange scenery. There was silence in his ears, and the only light source 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 glided in the water, a new scene would emerge from the darkness in front of him: waves, a jungle of tangled black water plants, a wide and flat muddy sand scattered with sparkling pebbles, and so on.

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

Suddenly, Mike's pupils shrank sharply.

In the darkness in front of him, it seemed that some huge object was slowly moving towards him.

Mike could guarantee that it was definitely not a human being. No human being could grow to such a large size.

Normal people would inevitably feel fear in their hearts when encountering such a situation. This is the fear of ancient 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 object slowly floating towards him was not Harry and his friends, Mike raised his magic wand without hesitation.

"Thunder Explosion!" '

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

"Bang!"

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

strong water flow swept over, stirring the lake water into a turbid state, and Mike's field of vision was reduced again.

At this moment, Mike was no longer arrogant and directly launched his magic perception. Although the magic perception was obviously suppressed underwater, it was better than seeing nothing.

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

They moved very fast and came to Mike's vicinity in an instant, as if they were afraid that Mike would escape.

However, Mike stayed where he was and did not move.

He had guessed the identity of these creatures, mermaids.

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

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

They had green hair and beards, gray skin, and their upper bodies were full of muscle lines, while their lower bodies were covered with scales. It can be

seen that they have a high level of intelligence and have even learned to tame animals, because they still have ropes in their hands, and the other end of the rope is tied to a Grindylow - a water monster with horns on its head that likes to attack people who fall into the water.

To be honest, Mike was a little disappointed, because these fishmen were just like what was written in the book, not only were they not beautiful, but their faces even looked a little hideous.

While Mike was observing these mermaids, the 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 tell whether this strange creature in front of him was a human.

Mike was about to state his identity and ask the mermaids to let him go, but he saw the Gundam mermaid pointing at his short golden hair and making a lot of noises as if he had discovered something incredible. The

other mermaids beside him all smiled grimly, then loosened the ropes in their hands, pointed at Mike and made a series of strange noises. The next moment, the group of Grindylows rushed towards Mike like hunting dogs. Seeing this,

Mike's face darkened and he took out his magic 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 Thunder Explosion!"

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

The mermaids in the distance opened their mouths wide and looked at the shocking scene in front of them in surprise.

"This is different from what we said at the beginning! That human deceived us! That blond guy is not a human cub at all! A human cub cannot have such terrible 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 were all young mermaids who had lived in the Black Lake since they were young.

Although their elders told them about the power of wizards every day, they had never seen the power of wizards with their own eyes and always thought that the group of humans living in the castle were just like that. In

addition, the mermaids have been multiplying in the Black Lake for many years, which has also caused the resources and territory in the Black Lake to gradually dry up.

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

At this moment, they finally saw the power of wizards, and Mike's amazing power scared them directly.

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

But where can they run to?

Judging from the continuous explosions just now, Mike's attack range is amazing, and they can't run away at all.

However, Mike on the opposite side did not intend to continue using large-scale blasting spells.

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

Unfortunately, the mermen on the opposite side did not think so.

They chatted again for a while, and then the mermaid with a huge horn on his back in the other team took the horn with a serious face, put it to his mouth and blew it vigorously. A

low, roaring sound like an ancient beast came from the huge horn, and gradually drifted away under the guidance of the water flow.

The frightened look on the faces of the mermaids who had finished blowing the horn was of course gone, and instead they laughed and roared arrogantly to the extreme, as if they had already won.

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

The next moment, Mike, who was still using his magic perception, found a huge monster swimming quickly from a distance. From the general outline, it seemed to be a giant octopus!

The water monster octopus of the Black Lake!

Mike instantly had the urge to curse.

If he faced a monster of this size on the ground, Mike would 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 could not be used, which made him no match for the opponent at all.

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

These Grindylo obviously also sensed the arrival of the giant octopus, and were now swimming in the direction of their master in fear.

With their help, Mike's speed increased by several levels, and the smiles of the mermaids who were originally in high spirits froze on their faces.

"(Mermaid language) Run!"

No one knows who shouted this, and the mermaids immediately scattered and fled.

Unfortunately, how can humans outrun hunting dogs?

Similarly, these mermaids can't swim faster than these Grindylows that they have trained as hunting dogs. In a short moment, the group of Grindylows led Mike to catch up with the fleeing mermaids.

The faces of the mermaids sank, and they raised their tridents to fight Mike to the death, but the next moment Mike had already raised his magic wand.

"God's sword without shadow!"

As Mike roared, the mermaids were suddenly cut in half, and large streams of green blood gushed out.

Mike kept controlling the group of Grindylows to continue swimming in the direction indicated by the magic wand at the beginning. As long as the Grindylows deviated from the direction, Mike would whip 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 appeared faintly in front of him.

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

Mike knew that it must be that damn octopus catching up.

Turning his head, he saw that a huge black shadow had covered him, and a huge tentacle stretched out from the shadow and grabbed Mike.

"God's Edge Shadowless!"

The huge tentacle suddenly stopped moving, 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, and finally the entire huge tentacle was broken.

"Roar!"

The terrifying roar came again, but this time it was obviously a little angry.

There was no need for Mike to urge them, and the Grindylows swam desperately towards the village.

Mike was concentrating on looking behind him, resisting the monotonous tentacle attack of the giant octopus.

This attack mode was really monotonous. Mike swung his magic wand repeatedly, and all the tentacles that the giant octopus pulled over would be cut off by Mike's God's Edge Shadowless Curse.

The surrounding waters had been completely dyed blue by the octopus' blood. The big octopus began to twist its body crazily in pain, and under its influence, the entire Black Lake became turbulent.

The mermaids in the mermaid village naturally discovered such a big commotion. A large number of mermaids holding tridents swam out of the village, and at the same time, a horn with a tone that was obviously different from the previous one sounded in the village. Hearing

the horn, the giant octopus's movements suddenly stopped, 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 did not work. After they reacted, they gritted their teeth and rushed towards the giant octopus.

Behind them was their home, and they would never allow the giant octopus to rush in and destroy it!

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

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

There are caves everywhere in the village, and some strange-shaped boulders. These stones seem to be the homes of mermaids, because there is a door on the stone!

In the center of the village is an open space, where a large number of mermaids are gathered, looking worriedly at the soldiers fighting the giant octopus.

Behind them stands a rough mermaid statue, and four people are tied tightly to the tail of the mermaid statue.

Ron is tied between Hermione and Penelope, and there is also a little girl who is no more than eight years old. Her silver hair like clouds makes Mike sure that she is Fleur's sister.

The four of them look like they are sleeping soundly, their heads drooping weakly on their shoulders, and strings of fine bubbles keep coming out of their mouths.

Next to these four people is a half-human, half-shark monster.

That's Krum!

At this moment, he was pulling and biting the rope on Hermione. The problem was that Krum's shark teeth were very strange. He had a hard time biting anything smaller than a dolphin. Such delicate work as biting the rope was obviously not suitable for him.

Mike swung his wand and the ropes tied to the four people broke.

Krum was stunned at first, then he looked at Mike with gratitude and grabbed Hermione's waist and was about to rise to the surface.

Mike roared, "Stop! Save the others, it's not safe here anymore!"

Krum stopped. Of course, it was not Mike's words that stopped him. In the water, neither of them could hear what the other was saying.

What really stopped him was Mike's wand pointing at him and his cold eyes.

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

Swimming back tremblingly, Krum felt that he was embarrassed.

Michael didn't care what he thought. He tied all four people to Krum, and then tied Krum with a magic rope just like he tied up Grindylow before.

"Go!"

Michael shook the rope, and Krum understood. He gritted his teeth and dragged the four people to the surface of the water.

Relieved, Michael looked towards the direction of the mermaid village before leaving.

The mermaid soldiers still couldn't resist the giant octopus. At this moment, the monster had rushed into the mermaid village and was wantonly destroying the village.

Houses collapsed, screams continued, and mermaids were fleeing everywhere.

Michael mourned for these mermaids for a while, and continued to be led by Krum to the surface of the water.
