Professor of Pharmacy at Hogwarts

"This doesn't look like a treasure trove."

As they walked around the lake and along the edge, Harry couldn't help but whisper.

"what!"

"Harry, who told you there was a treasure here?"

Harry was speechless for a moment.

"But that's not necessarily what you said. Maybe there really is a treasure inside."

Harry glanced at the glowing green lake, and couldn't help but think of various legends in his mind, such as water monsters, water monsters, water ghosts, giant pythons and ghosts...

Then, whether it was excitement or fear, Harry's body trembled slightly.

While Harry was thinking wildly, Black in front had stopped. Harry didn't pay attention and bumped into Black, almost knocking Black into the lake.

"Sorry, Blake."

Harry came to his senses and apologized quickly.

"It's ok."

Blake shook his head. "There is no road ahead." He pointed forward and said.

When the two of them first started walking around the lake, the rocky road on the edge was very wide. But as the two of them continued to move forward, the road began to become narrower and narrower. At this point, there was no road ahead at all.

Black stood in front and frowned in thought. Harry looked around, and then couldn't help but said, "It would be great if there was a broomstick."

"Maybe I should go out with my Firebolt."

Blake's eyes lit up, and he took out the small cloth bag and rummaged through it again.

"Maybe that bastard Alexis has something for us."

"Look!"

Just as he was talking, Blake took out a broomstick, which was a Nimbus 2000.

"Harry." Black handed the broomstick to Harry, "Let's fly over!"

Harry was a little hesitant. Although he performed well in the flying class, the situation in front of him was obviously not as simple as what he encountered in the flying class. What if they fell into the lake if something went wrong.What if there happens to be a water monster or something like that in the lake...

Harry simply didn't dare to think about it anymore, it would be a disaster.

"I've seen your performance on the court, Harry, believe in yourself, you can do it."

Facing Blake's encouraging gaze, Harry nodded and took the Nimbus 2000.

This is a brand new broomstick, it even has packaging that hasn’t been unpacked yet.

Harry sat astride the front, his palms tightly gripping the handle.

"Okay, I'm ready."

Black sat behind Harry and hugged Harry with one arm. After a semester, Harry still hadn't gained weight, and he could wrap one arm around Harry's waist.

"Harry, you are too thin. You need to eat more."

Blake couldn't help but said.

Harry nodded, activated his broomstick, and the two of them dived into the darkness.

"Fly forward! Harry, we need to fly to the other side!"

The salty wind whistled in his ears. Harry gradually let go of his worries and became excited. He couldn't help but speed up again. Nimbus 2000 was like a meteor, swishing through the darkness and flying towards the opposite side. .

The cold wind blew against their faces, and the strong speed brought an indescribable sense of excitement. Harry and Black soon forgot their nervousness and started shouting in the air.

It turned out that the lake was not as big as they thought. They flew for less than a minute and could already see the other side.

Harry lowered his altitude and prepared for landing.

At this moment, there was a sudden explosion-like noise below them, and a big white guy emerged from the lake and rushed towards them.

Harry was startled and quickly changed direction, narrowly avoiding the big guy.

puff-

Before Harry could see clearly, the big guy fell into the lake again and disappeared.

"It seems I was right, Harry. The lake is indeed dangerous."

Valley</span>After landing, Blake said with a smile.

"What it is?"

"I didn't see it clearly either. Maybe we can try to study it later."

This is a smooth rock island, surrounded by green lake water, and the atmosphere is a bit eerie.

Harry grabbed the broomstick and followed Black. The two came to a stone basin.

The stone basin is in the shape of a hemisphere, and there is a base underneath, which looks like it will fall over when pushed.

The stone basin is filled with green liquid, which emits sparkling phosphorescence.

This reminded Harry of his experience when Alexis took him to Snape's office. The liquid inside looked similar to the potion that Snape brewed at that time, and it didn't look like a good thing.

Black was very brave, and while Harry was still struggling to remember whether this liquid had been taught about this liquid in Potions class, he had already reached for it.

"do not……"

Harry only had time to utter a single word before he saw Black's fingers hovering above the liquid.

Black withdrew his hand and started pushing the stone basin with his good arm under Harry's worried gaze.

The stone basin was stronger than they thought - it didn't fall over when pushed, and even with Blake's best efforts, it didn't even sway.

"Maybe the treasure is hidden in here, Harry. Think of a way."

Blake joked.

He took out his wand and cast several spells in succession, but the stone basin remained motionless and the green liquid inside did not decrease.

While Harry was still thinking about how to overturn the stone basin, Black had already taken out a pipe and inserted it into the stone basin.

The tube encountered no obstacles and passed smoothly through the green liquid surface to the pelvic floor.

"Looks like I need to drink it."

Blake sighed and said in disgust.

"what?"

Harry was shocked.

"No!"

He quickly stopped Blake.

"Blake, this is not a good idea," he said. "Who knows what these liquids do, and even if it doesn't originally kill people, who knows how long they have been there, maybe they have gone bad, like cheese. Same, spoiled! Broken!"

"Don't worry," Blake laughed. "I'm sure they haven't - oh, they've gone bad! They're still - within the shelf life!"

After saying that, Blake lowered his head and took the straw in his mouth.

The green liquid entered his mouth along the straw, and the liquid level in the stone basin began to drop visibly to the naked eye.

"Blake?"

Harry held his breath and called out cautiously.

Blake didn't answer him, and the liquid level in the stone basin was still lowering.

"Blake? Are you okay?"

Blake still didn't answer him, and the liquid level in the stone basin began to decrease slowly.

Harry stared at Black with wide eyes, a sudden fear welling up in his heart.

What if something happens to Blake?

Is he going to lose Blake?

He suddenly thought of what several Slytherin classmates had said secretly:

He is a disaster, a complete disaster!I heard that whoever gets close to him will suffer bad luck!Or even die!

Do you yourself...

Just as Harry was thinking wildly, the liquid in the stone basin had bottomed out, but Blake closed his eyes tightly, frowned in pain, and lay beside the stone basin, trembling all over.
