My Black Magic Is Too Good, It Can Be Automatically Whitened

At noon the next day, all the Hogwarts students who were temporarily notified of the suspension of classes gathered by the lake.

All four of Dunn took off their shoes and stood barefoot on the pebble shallows by the lake.

Slughorn, who was the referee for this match, gave each of them a piece of gills and told them to chew it one last time before swallowing. Although it didn't taste very good, it could make the medicine work faster.

Dunn, Mera, and Harry all followed suit without hesitation, only Ronald hesitated visibly.

In the end, he resisted the nausea, put a piece of gills in his mouth, and swallowed it directly without chewing it at all.

Even so, he still clutched his neck and retched for a while, and almost spit out the gills that he had eaten.

While Ronald was still battling nausea, the gillgrass that the three Dunn ate had started to take effect.

As if something suddenly blocked his nose, as soon as he inhaled, it felt as if the surrounding air had been evacuated, the lungs were empty, and there was a sharp pain like a knife on both sides of the neck.

Harry hugged his neck uncomfortably, and felt two long, narrow slits behind his ears.

Turning his head, he found that Dunn and Mera, like him, had gills growing behind their ears, opening and closing like bellows.

It made Harry think of fish out of water.

Bang.

Water splashes everywhere.

Mera jumped into the lake for the first time, swayed flexibly twice, and then drilled into the bottom of the water.

Dunn and Harry jumped into the lake shortly after.

I don't know if it's because of eating the gills, but when I just stood on the shore, I felt that the lake water was freezing cold, but when I actually entered the lake, I found that the water was not as cold as I imagined.

The most important thing is that they can breathe in water.

Taking a deep breath, you can feel the lake water flowing smoothly through your gills.

The suffocation that had just been on the shore was immediately relieved.

Harry raised his hands in amazement to find that there were real webs growing between his fingers.

The same goes for the feet, and the toes are elongated, like a frog's foot, into a very large web.

Dunn and Mera had already swam by Harry's side as he watched the changes in his body.

They can't communicate with each other in the water, only through gestures.

Harry said that he would stay and wait for Ronald, and let Dunn and Mera go first.

Dunn and Mera looked at each other and headed down the water together.

On the shoal by the lake, Ronald stood in the icy water, shivering from the cold wind blowing through.

There were genuine whispers on the shore, Ronald could even feel that some people were pointing at him, probably mocking him.

Slughorn came over, a gillsweed in his hand.

"You just swallowed it without chewing, did you?"

Ronald wanted to lie and say that he chewed it, but the effect of the drug was slower, but when he met Slughorn's bright eyes, he immediately felt guilty and had to nod to admit it.

"Then there's no way." Slughorn shrugged, "Eat this too, remember to chew it before swallowing. 99

Ronald asked in a panic.

"Professor, didn't you say you can only eat gills once a day?

"Who said you can only eat it once a day? It doesn't matter if you eat a bundle, it's a bit of a bad stomach at most, it's just that the gillgrass will only take effect once a day, well, eat it quickly, your partner is still waiting in the water How about you! 99

Ronald turned his head and saw Harry stick his head out of the lake in the distance and wave him hard.

In desperation, Ronald closed his eyes, stuffed the gills in his mouth, and chewed it hard.

Dunn and Mera, who were already deep in the lake, were swimming around in a strange, dark, hazy landscape.

Mera held up her wand, the top of which fluoresced, illuminating the scene at the bottom of the lake.

The jungle composed of undulating and tangled black water plants, the broad and flat sand scattered with shiny pebbles, from time to time small fish swam swiftly by the two of them.

From time to time, there will be one or two larger shadows swimming past overhead, probably some large fish.

With his wand in hand, Dunn watched his surroundings vigilantly.

At this moment, Mera suddenly shook his arm and pointed to a dark green water plant not far away.

The grass was two feet deep, and from a distance it looked like a neat lawn, undulating with the current at the bottom of the lake.

In the middle of the aquatic plants, a golden egg appears and disappears!

Mera swam over there quickly, but was caught on her hind legs.

........for flowers.....

Before she could turn around, a spear-like sharp wooden stick slid in front of her.

Dunn grabbed Mera's feet, dragged her back, and placed a defensive spell on both of them.

More than a dozen male mermaids emerged from the water plants together, and the leading mermaid said a word to his companions, followed by more wooden sticks and spears to shoot at the two of them.

Mera understood what the merman was saying, and turned back in horror and gestured hard at Dunn.

Dunn quickly understood what Mera meant.

These merfolk want to kill them!

After blocking the attack of the next wavelength spear, the effect of the defensive spell is not as good as before.

Dunn saw that everyone behind the mermaids was carrying a dozen spears, and immediately blessed himself and Mera with an iron armor spell.

00...

After giving Mera a retreating look, Dunn took the lead in swimming towards the lake.

Mera reluctantly glanced at the golden eggs in the grass, separated her arms, and caught up with Dunn.

The mermaid who launched the attack did not give up and chased after them one after another.

A spear kept passing by the two of them.

Those spears that might hit their bodies were stopped by the Iron Armor.

A fish was speared in two pieces in front of Dunn, and the blood that came out was dark green.

This made Dunn even more sure that the group of merpeople who were chasing the two of them really wanted to kill them, otherwise it would be impossible to poison the spear.

Whoosh!

A white light shot from the tip of Dunn's wand, hitting a space in front of the chasing merman.

The chasing mermaids thought that Dunn's spell had missed, and they rushed over.

The six mermaids rushing in front suddenly stopped after passing through the area hit by the white light, and countless fine and neat blood lines appeared on their bodies.

The blood burst open, and the shredded body sank toward the bottom of the lake like a collapsed building block.

The mermaids in the back were all frightened and stopped chasing.

Turning around, Dunn didn't intend to let the shameful attackers go. The green light from the top of his wand shot out one after another, killing the merman who was hit by the Killing Curse instantly.

Mera also waved her wand and joined the attack.

Soon the dozen or so mermaids that attacked them were all slaughtered.
