The Deep Sea Wizard of Hogwarts

As he spoke, Old Sere stood up slowly and firmly and walked to Harry's side.

"Remember, you are from Atlantis." He said to Harry, and then put the golden trident in Harry's hand.

At the same time, many symbols that Harry did not recognize suddenly appeared on the ground. They combined together and flowed slowly, like some kind of magic circle.

Old Sere put the trident in Harry's hand, then grabbed Harry's hands tightly and pointed the tip of the trident at himself.

"I hope what you said is right." He glanced up, and Harry looked up, only to see an eye floating above the cave, and this eye was staring at the two people below.

The eyeball split from the middle, revealing a mouth growing on the eyeball, and the mouth was full of sharp teeth with bloodshot.

Harry was frightened by this scene and trembled. When had he ever seen such a scene?

"I'm not right, am I? You killed Gario and stole the Abyss Slate, thinking that you could learn these secret books with your biologically modified little guy.

In the end, you failed halfway, leaving behind a biological core and a giant squid." The eyeball spoke.

At the end, he muttered, "In the end, you can only migrate to the Black Lake!"

Old Sere didn't say anything, but there was a look of desolation in his eyes. Then he looked at Harry's face, "Fortunately, I have survived until now with the Abyss Slate, otherwise how could I have met this little guy! He is simply a gift from God to me."

He looked fanatical, grabbed Harry's hand, and stabbed the trident into his heart.

"No!" Harry shouted in horror, trying to pull his hand out, but found that Old Sere's hand was like an iron hoop, holding it tightly.

Harry widened his eyes, not understanding what Old Sere wanted to do. His heart was stabbed, but his eyes were more energetic. One hand grabbed Harry tightly, and the other hand followed the trident and reached into his chest.

The sound of flesh squeezing entered Harry's ears, and Old Sere pulled hard, pulling out a dark black slate the size of a book.

"Listen carefully, kid. This is called the Abyss Slate. It records the method of becoming a sea beast sacrifice and the exclusive spells. It is also the key to my survival until now. It contains unimaginable power."

It seemed that this slate was his heart. Once it was taken out, Old Sere began to decline gradually.

"Now it's yours." Old Sere pressed the slate against Harry's chest. Then Harry saw the slate slowly melt into his chest.

It was like putting a hot rock in ice and snow. Harry wanted to stop it, but his hand was held tightly and could not move at all.

But in the blink of an eye, the slate entered Harry's body.

Then, Old Sere pointed his finger at Harry's forehead. Then, a large amount of knowledge without malice entered Harry's mind.

The language of the merman, the history of the merman, the siren, the naga, the merman. The history of Atlantis. The degeneration of the merman: the ancestors, the survivors, and the abandoned people.

This knowledge quickly became part of Harry's memory, and at the same time, Harry also knew the name of the old merman in front of him.

Yu San, if translated into English, is Seri Fisher.

What Yu San passed into Harry's mind was not only knowledge, but also his beliefs over the past few hundred years, and the common dream of Yu San and Jia Liu...

A large amount of knowledge poured into Harry's mind, instantly stunning him. At the same time, Yu San, who gave everything to Harry, also fell slowly.

The runes on the ground also began to lose their luster slowly.

In the quiet cave, the only living thing that was still moving was the swimming eyeball monster.

He flew to Harry and looked around him several times.

"From now on, you will be the sea beast priest: Harry Potter!" After saying that, he spoke lightly to the bottom.

"Send him back. It won't be long before Harry Potter will be your master." After saying that, the cave entrance blocked by the boulder was broken open, and two giant squid tentacles drilled through the long corridor, sweeping away Harry and the trident.

After Harry left, the eyeball monster suddenly grew several times larger, and then began to plunder the cave like a jelly bean man. He took away many books and medicines inside.

After looting the cave, the size of the eyeball shrank back again, and those substances swallowed by it were unknown where they went.

After that, it glanced at the body of old Seri and said nothing. Instead, it lost its life, as if it had died suddenly, and fell into the water powerlessly, the flesh and blood slowly melted, and then was quickly separated by the water.

It was as if this eyeball had never appeared.

The fishman village outside did not become restless, as if old Seri had already made arrangements for his funeral.

————————

When Harry opened his eyes again, he saw himself lying next to the Black Lake.

The rain had stopped at this time, and I don't know how long it had been. The moon shone on the Black Lake, sparkling like his scales.

He has now turned back into an ordinary boy.

Harry rubbed his aching head, and Harry, who had accepted the language of the fish people, also understood what had happened.

Tonight, the sea monster named Yu San deliberately attracted him to the Black Lake, and then tied himself to the cave. He gave him the secret book of sea beast sacrifice, "The Abyss Slate".

Thinking of this, Harry rubbed his chest, which contained the Abyss Slate, and it and his heart were now in a symbiotic relationship.

Although the Abyss Slate is called a secret book, it has nothing to do with books. The method of practicing the secret art of sea beast sacrifice is engraved on the slate. To obtain the content inside, you can only get it by integrating the slate into your body and achieving a symbiotic relationship.

At the same time, Ceri seemed to have used some other method to let Harry skip the ritual of becoming a sea beast sacrifice. In other words, Harry is now a sea beast sacrifice.

To be more precise, Harry will naturally become a sea beast sacrifice in a few months. Because his body still needs an adaptation stage.

Harry sorted out these sea beast sacrifices and looked at his side.

At the same time, he was given this-

He raised the golden trident lying with him with both hands.

The human self would definitely not use this thing as a weapon. Harry thought to himself.

This is the weapon of sea beast sacrifice.

Harry used to not reject the fact that he would transform into this half-man, half-fish appearance because this appearance would be particularly comfortable in the water, and this posture helped him escape from the Dursleys.

Now, he not only does not reject it, but naturally accepts his identity as a fishman. Although he still does not know why he has such an ability, as the knowledge given to him by Yu San is integrated into his mind. His thinking is also affected.

Now Harry is imagining in his heart what it will look like when he uses the magic of sea beast sacrifice in the future to show his power in front of Ron, Jane, Hermione and others.

The ability of sea beast sacrifice is mainly to drive sea beasts and borrow the power of sea beasts.

Thinking of this, Harry put on his wet clothes, wrapped the trident with a robe, and tiptoed back to the castle.

At the same time, he did not forget what he encountered with the big snake Thad.

But he encountered too many things, and he was thinking about how to tell Ron and others. This kind of thing must be shared with his good friends, Harry thought.

But he should tell Dumbledore first. Thinking of this, he felt a little ashamed for no reason.

Why did he cause trouble for Dumbledore every day.
