Aragog looked at Harry in disbelief.

There was a strange and eerie luster in the eyes with cataracts and presbyopia.

Send your own child away... to be used as a teaching aid?

"Human wizard, do you know what you are saying?" it spoke slowly.

Harry curled his lips: "Don't pretend to have feelings for your countless generations of children. You are giant acromantula."

This creature...

When the pressure of survival is too great, these dark magical creatures will treat their own kind as food.

"Or, I can kill you all right now," Harry said softly, "and maybe squeeze out dozens or hundreds of pints of venom?"

"It's a little less, and it's only the amount for this time, but it's enough for two or three years."

"Or, let's cooperate well."

"It's for Hagrid's sake that I'm so patient discussing these things with you."

"Anyway, you can only live for another six months."

He spoke softly and in a calm tone, but the aura of anxiety and annoyance coming from Aragog was growing stronger.

Harry waved his wand gently.

The wind blew violently, and the branches and leaves rubbed against each other, making a rustling sound.

Dark clouds rolled in, revealing a gloomy light, and then thunder rumbled, singing in unison with the wind.

Weather spell.

Aragog took two cautious steps back, becoming even more uneasy. After a while, a few cool raindrops penetrated the spider webs and leaves and hit its head, causing it to speak: "Okay, human wizard, I promise you."

"But I hope the territory can be bigger..."

Harry waved his wand.

The strong wind died down, the dark clouds dispersed, a spider web overhead was washed away, revealing a large empty space, and the bright moonlight sprinkled on the open space.

"Aragog, you have no choice."

He spoke softly.

"Hagrid, take it with you, we have to go sign the contract."

Harry walked back without hesitation.

Hagrid turned back, took out his wand, and tried to cast a levitation spell, but just after he had uttered a few syllables and waved his hands a few times, he was interrupted by sobs, forcing him to put down his wand and put it back in his pocket. He walked over and picked up Aragog, just like when he was still studying at Hogwarts, but time passed, and Aragog had grown into a huge monster.

Even with Hagrid's size, it was a bit difficult to pick him up.

But he insisted.

Until you walk out of the territory of the eight-eyed giant spider.

Harry looked at Hagrid. "Let Ron take Aragog back."

"We have to find Grawp."

Hagrid nodded, carefully put Aragog down, and warned: "Ron, Aragog is very old, and Harry said he...he..."

"I'll be careful." Ron waved his wand, lifting it with difficulty using the levitation charm.

Stay away from spiders.

Hagrid led the way: "Harry, come with me, I've put him in a very private corner."

"You know, the creatures in the Forbidden Forest don't like giants very much."

"The centaurs even had a quarrel with me once. I wanted to let Grawp live freely, but I had to imprison him."

As he talked, he led Harry through the bushes and paths.

The demon hunter sensed a thunderous snoring sound and a sour smell as if he hadn't taken a bath for several weeks.

The sound and breath became clearer and clearer.

An iron fence appeared in front of us, tightly enclosing the forest in front. In the middle of the fence, lay a giant covered in animal skins and of extremely large size.

"He was very angry at first. After all, he was locked up." Hagrid sighed through the fence. "Luckily, there's Olympe. Some spells won't be that harmful to giants. I was reluctant to do it at first. If it weren't for her, Grawp would have caused a lot of trouble along the way."

"I have been teaching him to read during this time."

"Harry, thank you so much."

"Thank you and Hermione for teaching me to read. Otherwise I would have a headache on how to educate him."

"It has little effect. He is still very rude, but at least, at least he has learned to use 'please'. He will say to me, 'Brother, please give me food.'"

"Did you tell him about the oath?" Harry asked.

Hagrid nodded, "Of course, it's just that he doesn't quite understand what the oath is. In fact, I don't quite understand it either, but Harry, you must be doing a good thing, right."

"Take him with you." Harry waved his hand.

Hagrid waved his wand, and a big door twisted out of the fence. He walked in and woke up his brother: "Grop, I will take you to sign the oath."

"HAGRIDDLE!" Grawp woke up with a start, slapping the ground angrily, making it rumble. "Bad Hagrid!"

"Locked up, hungry, and bullied!"

He climbed up swiftly, waved his fist and greeted his brother affectionately.

"No, not with your fists." Hagrid raised his wand.

Grawp stopped moving, looking fearfully at the small stick that was no thicker than his middle finger. "Hagrid, that's a threat! I don't like it!"

"This is Harry," Hagrid said gently, pointing at Harry, "He's a friend."

"Friends?" Grawp tilted his head and looked over. "Can friends be eaten?"

"No, no, no, friends are not food. Friends are friends, companions, and relatives." Hagrid corrected his mistake and taught him patiently, "Do you remember what I told you?"

Grawp frowned in agony.

"You can remember it," Hagrid encouraged him.

"We can't eat anything that's our size and can talk," Grawp said gloomily, finally remembering.

Hagrid's voice became cheerful: "Yes, you are great, Grawp."

He waved his wand, and a huge deer leg flew out from his pocket: "This is a reward."

The deer leg fell into Grawp's hand, looking even smaller than the chicken leg.

"Now we go to sign the pledge," Hagrid said softly.

Grawp swallowed the leg in one gulp. "A pledge?"

"Yes, that's what my brother said a few days ago." Hagrid nodded, "Let's sign the oath, my brother will prepare more food for you, and you can also have more friends."

"Food, friends..." Grawp repeated these two words.

He calmed down and nodded.

Hagrid carefully led Grawp back to the area where the magical creatures were.

Grawp was less careful.

He walked carelessly, trampling the bushes and bending the trees, his footsteps rumbling as he came towards us.

"Harry is back!" Hermione swung her wand and said fiercely, "Behave yourself, all of you!"

Ron looked up at Grawp.

This sixteen-foot-tall giant's face is difficult to see from this perspective.

Harry walked to the center, looked around, and looked at Hagrid: "Are all the creatures here now?"

Hagrid nodded. "Everyone is here."

Whether it is Grawp or the Acromantula, representatives of all creatures in the Forbidden Forest are now gathered here.

Harry raised his wand and cast a loud voice.

"Hagrid should have told you that the reason you were gathered together this time was to continue the oath made by Ms. Ravenclaw a thousand years ago."

"But the content of this oath will not only be limited to the Forbidden Forest, but will also be related to you."

The centaur shook his head. "As long as it is a fair oath, we will certainly accept it."

"Heir of Gryffindor, we are willing to believe you."

"I hope you won't betray our trust."

Harry smiled softly and raised his wand.

He slowly closed his eyes and felt the atmosphere of Hogwarts, ancient and simple, with courage, ambition, wisdom and purity intertwined together.

Reach out and grab it.

A gentle wave of the wand.

It turned into a school badge and stayed in front of Harry for a short while.

Harry raised his left hand, placed it on the school badge, and said softly: "As the heir of Gryffindor, I will sign a fair oath between Hogwarts and the Forbidden Forest."

The school emblem vibrated slightly, matching the aura emanating from the Sorting Hat.

Those magical animals all lowered their heads, pious and holy. Their breath was intertwined with the breath of the Forbidden Forest, forming a forest-shaped emblem next to the Hogwarts school emblem.

"Hogwarts will not disturb the ecological environment of the Forbidden Forest unnecessarily."

A golden light poured out from Harry's wand and landed on the Hogwarts school emblem, and then it also extended a golden light, shooting straight into the forest next to it.

"I'll take it," the centaur began, and the other magical creatures echoed him.

The forest badge emitted a golden light, which intertwined with the golden light of the school badge.

"No student or faculty member of Hogwarts will be allowed to kill creatures in the Forbidden Forest, with the exception of spiders that the Acromantula family voluntarily surrenders and are used as teaching aids."

"Similarly, no creature in the Forbidden Forest may kill Hogwarts students or staff."

The magical creatures looked at Aragog in surprise.

No wonder……

They were surprised, but that did not stop them from expressing their approval.

The second golden light intertwined.

"Hogwarts and the Forbidden Forest are friendly and mutually supportive. They are eternal allies. When necessary, the Forbidden Forest will help Hogwarts through difficulties, and Hogwarts will also help the Forbidden Forest through difficulties."

The magical creatures once again echoed.

The third golden light intertwined together.

"The oath is made, and those who violate it will be like Sisyphus."

After the last sentence was spoken, the magical creatures also agreed. The golden light flickered brightly. After a while, they disappeared, the forest emblem dissipated, and the Hogwarts emblem remained for a while - this oath brought some changes to the emblem. Three golden lines wrapped around the big "H" in the center of the emblem, weaving into the shape of a lush tree crown.

In the school auditorium and the principal's office.

The school emblem also underwent a slight change.

Dumbledore watched with a smile.

In the Forbidden Forest, Harry, who had just signed the oath, took out the parchment. Before the school emblem dissipated, he gently waved his wand to pry the power of the oath on the emblem. A faint white light was projected from the tree canopy and fell into the parchment.

Harry then took out a bottle of ink and poured it on.

The parchment map seemed to come alive.

Names popped up one after another.

Most magical animals do not have specific names, only their species names are shown. A few, like Grawp, were named by Hagrid, or like the centaurs, gave themselves names, and their names are shown on the parchment.
