I wield a sword at Hogwarts

The upper years seemed to enjoy teasing the younger ones for fun, as now, Malfoy told one of the younger students with a smirk.

As long as you see a mermaid underwater, you will receive a blessing.

The younger students believed it without knowing anything about the world.

Malfoy had a bad taste and said, "Actually, there is a more advanced blessing on top of the mermaid blessing."

"What is that?" the junior asked with admiration.

Malfoy smiled mysteriously and whispered: "Have you ever heard of the legend of John Underwater?"

"Underwater John?"

The junior's face was dull, he raised his hand and pointed at the huge glass, and asked: "Is it like that?"

Malfoy looked sideways, nodded and said, "Yes, it's like that. When you see John underwater, you can... wait!"

Malfoy turned his head suddenly and looked at John walking past under the water, his mouth wide open.

Really John underwater.

Re-enactment of classic scenes.

…

Chapter 470 Poisoned Suspect

Not knowing that he was being spread as a Slytherin ghost by Malfoy, John dived all the way from the Black Lake to the place where the giant octopus lived.

In what looks like an underwater altar, a giant octopus is lying there.

It was as if it hadn't moved since John left, maintaining its posture unchanged.

John still remembered what happened last time when he used psychic magic, so he was cautious not to use it this time.

Even with level 6 magic power, John could still feel the unusual power of the big octopus.

Maybe it really is an underwater version of Dumbledore.

"Elf of the Black Lake, if you can understand my language, please talk to me."

John used an extremely ancient language to spread under the water. He transmitted spiritual magic in one direction, so he was not afraid of being impacted by the thousand-year memory.

The big octopus, which was still sleeping, moved after hearing the sound.

It seemed to understand, its tentacles turned, and its big eyes looked at John.

The ancient charm was revealed in the big octopus, and John was delighted, and they really communicated with each other.

Now that we can communicate, everything becomes easier to talk about.

John lowered his posture and conveyed the voice in a humble tone: "Elf of the Black Lake, I am a student of Hogwarts. I need your help for something."

The sound entered the big octopus's head, and its tentacles moved, signaling for John to continue.

"I'm looking for the ancient blood and want to get it from your great body." John said his purpose without being pretentious.

"I am a person who abides by the agreement, and I can achieve my goals through transactions."

He stared at the big octopus, wanting to see what conditions this thousand-year-old being would propose.

But perhaps John spoke too complicatedly, or perhaps his language was not proficient enough.

The big octopus swung its tentacles there, and it took a while to digest what John meant.

Upon hearing that it wanted its own blood, the big octopus handed over a tentacle.

John was stunned, no request?

The big octopus swings its tentacles and reveals a happy feeling.

It seems to be able to help the students at Hogwarts, making it happy.

Compared to humans, the emotions of these creatures are purer.

And John dealt with these creatures in a human way, causing his thinking to fall into a dead end.

John looked at the big tentacle with a smile on his face.

It's because I'm narrow-minded.

In a world full of calculations, I have forgotten this purity.

I didn't expect to come here to look for the big octopus, and I was taught a lesson.

Expressing gratitude to the big octopus again, he was happy to see the tentacles of the big octopus swinging, and he was about to start taking blood.

Getting blood in the water is also a bit difficult.

John used magic to clear a waterless zone, and the big octopus curiously used another tentacle to cross back and forth.

A bottle of blue liquid was sealed.

"Thank you, respected Elf of the Black Lake, please allow me to use a bottle of wine I brewed to repay your generosity."

John took out a few stars, opened them and poured them onto the tentacles of the big octopus.

The golden liquid fell into the tentacles and disappeared quickly.

The big octopus was very happy, it liked this thing very much.

John smiled knowingly when he saw this, the stars were made of pure magic power, and all these magical creatures were very fond of them.

In the excitement of the big octopus, John saw the lake water quickly turning dark.

It's the big octopus spraying ink.

It was just the amount that made John very suspicious that the black color in the Black Lake was dyed by the giant octopus.

After collecting some ink, John was sent to the lake by the big octopus.

When stepping on the lake, the shooting star shoes kept John from falling.

He bid farewell to the big octopus.

The harvest this time was quite rich.

Let him lose track of time underwater and wait until he comes out.

He saw that the sky was dark.

Using magic to remove the water from his body, John walked towards the castle.

"The big octopus has a strong vitality. I think it can continue to live."

John didn't know how long the giant octopus could live, but depending on its posture, it would be easy for him to live until he died.

And the big octopus is still growing, which is the most surprising thing.

"Its size should be much larger than it was a thousand years ago."

Looking back at the black lake, John muttered: "Maybe one day, the big octopus will be bigger than this black lake."

When he thought of that scene, even John felt more and more frightened.

What about Voldemort, Grindelwald, the growth and vitality of the giant octopus are the most terrifying.

Back at the castle, John meets Filch.

He was sitting leisurely on the stairs, eating delicate snacks.

But that snack doesn’t seem to be sold by Honeydukes.

John glanced twice and circled Filch twice.

Filch muttered uncomfortably: "What are you doing?"

"Filch, how fast do you think you can run?" John suddenly asked a question.

Filch was stunned and said honestly: "You can reach Gryffindor Tower from here in one minute."

"Too slow," John frowned and said, "You can't do it at this speed."

"?" Filch's head was full of questions.

My speed is already a nightmare for students, is it still too slow?

"Have you ever heard that speed equals power?"

A gleam flashed in John's eyes, "I think you can be faster."

"The speed is just the limit of your shoes, not your limit, you can go faster."

Filch was confused by what John said.

But he remembered a saying, speed equals power.

In fact, Filch has a very outstanding ability.

That is, his eyesight is very good.

Even if he wears this pair of shoes that can reach flying speed, he can accurately catch people without hurting every student.

If he wasn't a squib, perhaps Filch would be a very good Seeker.

When Mrs. Norris saw John, she rubbed her legs around John's trousers.

Planting a faster seed for Filch, John heads to the Society of Stars.

He wanted to try and put the ink of the big octopus to good use.

For this kind of existence that has lived for thousands of years, everything on its body has an extraordinary effect.

But this time, he was stopped before he arrived at the Star Club.

…

school clinic.

"So he was like this after drinking?" John looked at Ron lying unconscious on the hospital bed with 10,000 doubts in his heart.

Dumbledore stood beside the bed, while Harry glared at John next to Ron.

His best friend was in a coma because of John's drinking.

Dumbledore said gently: "I checked the bottle of wine, and there is indeed poison in it that can kill people."

He looked at John with inquiry in his eyes and asked, "Did you give that bottle of wine to Slughorn?"

"That's probably true. After all, other wines don't have that mellow aroma." John nodded and admitted.

But his expression without any guilt made Harry very angry and said: "Why did you poison me!"

John looked at Harry as if he were an idiot, sighed and said, "Get some brains, Harry."

"If I'm going to take action, do you think this is necessary?"

John said calmly: "Obviously someone else tampered with the wine."

"Really, then who else would touch that bottle of wine but you?" Harry said.

"You need to ask Professor Slughorn," John said casually, "Many people can meet him."

"The most important thing."

John glanced at Ron, who was in a coma, and said confidently and easily: "Do you think it would be that easy for me to poison him?"

Two drops of emerald potion saved him, and John was not that low-end.

Although Harry was angry, he rationally told himself that John was right.

There is an emerald potion in Slughorn's office. If John wanted to poison him, he would not leave the antidote there.

It's just that Ron was unlucky. He drank the bottle of antidote in advance and drank the poisoned wine later.

Dumbledore didn't seem to think that it was John who did it from beginning to end. He acted calmly and wisely and said to John: "There is only one possibility. Someone entered Horace's office and poisoned your wine."

"Let's think about it, who has been in Horace's office lately?" said Dumbledore.

John said calmly: "I haven't been in since Christmas."

"Professor Slughorn is having a slug party, maybe that's where we can start."

This poisoning made John feel that there was a familiar handwriting.
