Slughorn said, and without waiting for Hoffa to ask, he pushed his shoulder and pushed him out of the room.

Out of the office door. Hoffa couldn't help looking back at the door of the potion professor.

In terms of attitude, the potion Professor doesn't seem to agree with fatil. But to rise to the height of the extinction of mankind, this is too exaggerated. And... Hoffa thinks that some of fatier's words are quite reasonable.

With the mermaid potion, Hoffa returned to the shore of Black Lake.

Here, there are nearly a hundred young men and women in swimsuits and trunks.

They were all wet, some coughing, some shaking with their arms, and some had already raised a fire to keep warm by the fire.

Just looking at it, there is another huge octopus in the lake. Its tentacles stretch out and throw a soft girl on the grass on the lake bank.

She was pale, shivering, and had some water plants in her mouth. As soon as he landed, he vomited out a large stream of water.

There is no doubt that these are the students who did not pass professor drasse's test.

He looked at the potion in his hand and thought that he could not swim at all. If the potion was not as good as he thought, he would go back to school to do the mechanical magic potion and herbal medicine work.

He pulled the cork off the bottle.

There was a pungent smell in the bottle, which was like the smell of rotten fish for three days.

Hoffa held his nose suspiciously and sipped the liquid in the bottle.

He looked at his body as if it had not changed.

He blinked and found something wrong. His eyelids closed from top to bottom and turned left and right.

He went to the lake and looked down.

His eyes have grown at least three times larger, and the faint golden lines are interwoven near a black vertical pupil, which is totally different from human beings.

He wanted to close his eyes, but found that he could not. He could only control a circle of film to move back and forth on his eyelids.

The changes gradually appeared in Hoffa. The hair on his head was entangled one by one, forming gray soft tentacles. A thin web palm appeared between his fingers, and a wide film appeared under his ribs.

All of a sudden, a cheek appeared under his neck, a sense of suffocation surged up, and his vision blurred rapidly.

He could no longer see normally, out of a totally irresistible instinct. He jumped into the Black Lake.

At this moment, he really felt what is like a fish in water. Different from last year's despair and fear when he entered the water, now he felt warm like amniotic fluid, as if he had returned to the state of the most primitive placenta.

The dissolved oxygen in the water exchanges gas with the blood through the capillary wall in the gill filament, which makes him breathe smoothly.

That pair of eyes, which are extremely blurred on land, can now clearly distinguish anything within 100 meters of him.

Blue lines appeared on his back and chest, and his skin began to secrete some unknown substances, making him extremely sensitive to his surroundings.

A small yellow croaker slowly swam past Hoffa's eyes. Hoffa's inner pupil turned, but his body was as motionless as a rock.

At this time, the instinct in blood makes him eager to try. He opens his mouth full of sharp teeth, grins to his cheekbones, and swallows the fish into his throat.

Then reason conquered instinct.

No, I'm a man, not a fish!

He opened his mouth again and spat out the fish.

The little yellow croaker was frightened and ran away from Hoffa quickly.

He turned his head and looked ahead. A pedal on the ground, like a sharp arrow rushed out, close to the ground delicate white sand, spine left and right shaking, in an instant swam out of the distance of hundreds of meters.

It feels great!

Hoffa, push again.

Speed up again.

The bubbles and current were far behind, and the purple morat tentacles on the reef at the bottom of the lake were startled and quickly recovered from the shell.

Hoffa, like a torpedo, easily caught up with the large crowd ahead.

Because of the speed, he even has leisure to observe the surrounding scenery.

The sunlight has been shining down to the bottom of the lake 30 feet below the water. The light is refracted and deformed like a prism. The reefs, germ, shells, corals and some unknown magical creatures at the bottom of the lake change slightly in color after being refracted, showing seven colors. A variety of color combinations interlaced, a red orange yellow green blue purple colorful beautiful image.

A hundred meters away, the lake is dark blue. Hoffa's eyes penetrate the gray and treacherous lake, looking at the dark shadow in the distance, where the lake is dark and hazy. A faint outline of a huge octopus waves its tentacles in the Black Lake.

Above him, countless students swam hard. They couldn't reach the depth of Hoffa. The water pressure was too high.

When he saw the crowd swimming with all kinds of magic above, Hoffa had a whim. He stepped on the ground, went up, and stopped less than one meter near the water. There was a girl swimming with a school of fish on it.He lay comfortably in the water with his face up, enjoying one body after another full of youthful vitality in the water.

He was comfortable, but some girl who was struggling to row bowed her head. Seeing the strange Mermaid face under his body, he was almost scared out of his wits.

"Ah

The scream immediately triggered a chain reaction, and the students across the lake noticed the difference. They all looked down.

The whole black lake is like a frying pan.

The fish jumped up in horror, and all kinds of magic floated around. The magic spell goes into the water and turns into a boiling water column.

Hoffa deftly dodged all kinds of magic charms. He touched his face and couldn't help laughing, pushing the girl out of the water. Then he disappeared at the bottom of the lake and continued his deep diving journey.

Far away from the frightened crowd, he came to the middle of the Black Lake. Here, the scenery in the Black Lake began to change, and the lake became deeper and deeper.

Here, Hoffa saw some relics of the wrecked ship, including iron kitchen utensils, anchors, chain rings on the pulley, mortar guns, fragments of astronomical instruments, and a piece of stern railings. On them grew dark green plants at the bottom of the lake.

Not only that, in the forest like algae vegetation at the bottom of the lake, Hoffa also saw some rusty and deformed cages, which were floating among the algae, with some rotten bones inside.

Some of the white bones are chained to the limbs, so it seems that they are all human.

This scene made him feel uncertain.

Now he was close to the huge octopus in the Black Lake, waving its tentacles like a thick forest at the bottom of the lake.

At this time, there was a student in the distance who was probably exhausted and went straight to the bottom of the lake. Immediately, a long tentacle passed by Hoffa's face,

although there was not much sound, he still saw the dense suction cups and barbs on the tentacle.

This picture makes him feel scared. He nimbly gives way and swims forward. But the giant octopus didn't look at Hoffa, with its eyes closed and its tentacles floating in the water.

If a student is perceived to be drowning, the tentacles will reach out, roll up the student and push him back to shore.

As he swam right above it, Hoffa saw the bottomless, stacked sharp mouthparts of this great creature. It's like a black hole. Even in the form of a mermaid, the mouthpiece makes Hoffa flustered.

This creature has almost infinite magic power. It shouldn't be here. It should live in the sea. Maybe Black Lake is just a pond for it.

After passing through the lake bottom forest composed of octopus tentacles, Hoffa's speed gradually increased, and he caught up with one student after another. Finally, like a torpedo, it flashed by the bottom of the lake, leaving a series of bubbles.

Half an hour later, he swam over fifty kilometers to the other end of the Black Lake. At this time, the potion effect on him gradually disappears.

The lake bank is close at hand. He climbs up the grass wet, and his body gradually disappears due to the change of magic medicine.

Here, a few sporadic senior students panting on the grass to rest, a few students are very professional activities of their muscles, adjust their state. They are the top students in this group.

Miranda and aglia are tidying their hair on the grass, talking one after another. When they see Hoffa coming out of the water, they are all surprised.

At the moment, Hoffa has not fully recovered to human form, with a large number of cartilaginous fish characteristics on his body surface.

Stunned for a while, Miranda asked, "is that your new transfiguration?"

"No Agraia glanced at Hoffa. "Mermaid potion."

"Well." Miranda immediately showed a smile, "what is Mermaid potion, you tell me."

Agleia reflexively wants to make a long speech to show off her rich knowledge of potions, but when she sees Hoffa looking at herself, she stifles her desire to speak. Turn your head and look at the lake.

Miranda made a face at Hoffa and shook her head helplessly.

At the moment, Hoffa's medicament changes have almost disappeared, his eyes have returned to normal human state, and the surrounding scenery has gradually become clear.

This side of the lake is very, very far away from Hogwarts. You can hardly see the castle, but you can see huge boulders here. And the mountains of Scotland.

Hoffa often looked out at Ravenclaw when he was in the common room, but it was his first time.

On the grass not far from the lake bank, there are two tables covered with large canvas. The surface of the table is slightly raised, and I don't know what is covered below.

On the grass next to the table, young looking professor fatil drassez was leaning against a pebble. He did not talk to his daughter or the successful students crossing the lake.

He looked at the sky, the whole person showed a negative nihility to the extreme state, as if his spirit had been swallowed by something.About another 30 minutes later, another group of successful witches came out of the Black Lake breathlessly. There were about a dozen of them. As soon as they got ashore, they collapsed and their chests heaved violently.

At this moment, Professor drassez stood up, walked through the crowd, came to the Bank of the lake, and looked at the lake without squinting.

It was getting dark, and no one came to the lake.

A Lake crossing ceremony eliminated 90% of the people, and only less than 10% remained.

Looking at the lakeshore, dreises sighed deeply. He put out the smoke and rubbed his temples with a painful expression. Finally, he turned and clapped his hands.

At this moment, when the moon was born, the lines of Professor drassez's face seemed to soften in the moonlight, and Hoffa found that he and agraia had amazing similarities in facial contour. Except for the color of his eyes, he is almost like his daughter's twin brother.

"Tired?" His voice was hoarse but soft.

The crowd did not answer, just looked at him, want to know what course he would take out.

"You are very good. People who can walk here must have found some unusual fun in the just crossing the lake. After that, in every class of mine, you will learn to deal with chaos and the unknown. "

He waved a magic wand, a light spot flying around, illuminating the grass on the shore of the lake. Everyone's shadow is on the ground, shadowy old elder. The sound of rustling came from the wooden table behind, and the magic curtain was slowly opened.

With the exclamation of the students, Hoffa's pupils shrank. Yes, he saw nearly ten young fire dragons curling up on a row of wooden tables, smoking.

Fatil looked proud: "dragon. One of the top predators in the magic world, the fastest way to become an elite creature is undoubtedly to observe the top predator and grow up with it. "
