Harry dove into the lake.

The killer whale potion made him swim very fast in the water.

The bottom of the lake was much cleaner than the Black Lake. There were no boots thrown in by students, no dusty necklaces, sculptures, or portraits, and there were not even any messy dead branches or gravel. The lake had a perfect arc shape, and a few clumps of delicate swaying water plants, with an exquisite feel like a bonsai that Professor Sprout had blended.

Even the sunlight came in unhindered, spreading evenly over every spot on the lake bottom.

The sword in the lake sank in the southwest corner.

Harry found it without difficulty.

Avalon focused on loving everything about him, except for this sword.

Underwater, it's rusty, its shadow ripples in the water, and an aura of ancient magic hangs over it.

Harry waved his wand.

Checking the magic above, there is no portkey, no dark magic, and no magic to hide magic.

He opened the Sorting Hat, took out a little white mouse, put a Bubble Charm on it, and used the Floating Charm to drive it over. It touched the rotten blade of the sword in the lake and the hilt wrapped in loose linen, but nothing happened.

Safe and secure.

Harry grasped the hilt of the sword.

Magic power surged, and a bright light emerged from the hilt, pointing in a direction - just below the island in the middle of the lake. Harry swam over with the sword in hand. Under the island in the middle of the lake was a huge root system, and where the light pointed was a plain stone tablet with a small gap on it.

Harry thrust the sword in.

The lake water backflowed and rushed in towards him.

In the water flow, with a loud bang, the opened stone tablet closed again.

The light still poured in unimpeded. Harry got up from the ground, waved his wand to dry himself, and stood there, looking around carefully.

It was a room, completely empty.

There were a few dummies in the corner, and nothing else.

"Enter Avalon, a person who is wandering between life and death." A female voice sounded softly, "Are you also here to follow in the footsteps of King Arthur?"

Harry shook his head, "No, I just want apples to grow on the trees in Avalon."

"You came for the golden apple?" The female voice smiled. "I thought a swordsman like you would want the holy sword more."

Harry sniffed and activated his witcher senses: "There are two people on the island. I want to save them."

"Besides that, I am more interested in the sword in the lake."

"Them?" The woman's voice was low. "For friendship? Not driven by profit."

As her voice sounded, magic surged in the room. This fluctuation was just like when he faced the Mirror of Erised in the first grade.

"Oh, you are honest and you didn't lie."

"There aren't many people like you who have this kind of character these days."

Harry stared at one place and suddenly interrupted her: "Aren't you coming out?"

The female voice was startled.

The wall twisted, and a lady in a white robe with a spiral pattern walked out. She was holding a jar in her arms, and her face was a little pale: "Can you find me?"

"Where there is magic, there are traces," Harry answered him.

The lady looked him up and down, somewhat surprised: "Are you a wizard?"

A wizard wearing leather armor and carrying two swords? This was the first time she had seen one.

"How can we save those two people, grow golden apples, and feed them?" Harry asked her.

The lady raised her head, looked at the ceiling, and shook her head: "The golden apple can make the living live forever, but it cannot resurrect the dead."

Harry's heart skipped a beat.

"But don't worry, they are not completely dead yet." The lady chuckled and looked back. "They are not creatures of this world. The realm of death cannot control them. Moreover, the girl who sent them here is very smart and powerful. She can play with time and space and fix the two people in this moment forever until they are resurrected."

Harry's face was grim.

"As for resurrection, when the Apple of Avalon is signed, all creatures belonging to Avalon will be reborn, grow, and mature."

Harry took a deep breath. "Belongs to Avalon?"

"Geralt and Yennefer don't seem to belong..."

The lady shook her head: "They belong."

"That girl made a vow with Avalon. Those two belonged to Avalon before they were resurrected."

Harry's face grew even more serious.

Oath is a very ancient magic, or rather, it is ancient magic.

The Patronus Charm is a kind of oath, a promise made to oneself to uphold a good character. If violated, one will be eaten by maggots.

The Fidelius Curse and the Unbreakable Curse are also oaths.

The magic that Voldemort used in the reef cave was also an oath.

Animagus also signed a pact with the moon and nature.

Modern wizards rarely use or almost never use this kind of spell. It is not because of its power that it is eliminated, but because of the price. If you make a vow, you must pay the price.

“What did Ciri give?” Harry asked.

"She must never again set foot in Avalon," the lady replied quietly.

Harry was startled.

"She is very powerful." The lady saw his confusion and explained, "The power in her blood can play with time and space. She can go anywhere, even to other worlds. The oath can only restrict her actions in this world."

"Avalon needs to remain pure from the mundane."

At this point, the lady was a little distressed: "She travels too easily and too freely. We need to protect Avalon."

"So what does it take for me to make the Apple Contract?" Harry asked her.

The lady reached out her hand and held up the bottle in her hand: "This knight who has come from afar to revive his friend... wizard, are you ready for everything?"

Harry nodded.

"Starting from here, deep in Avalon, bordering the underworld, there is a tree guarded by the Winter Dragon. On it is a golden apple. Take the golden apple and use its endless vitality as nutrients to make Avalon grow again." The lady said softly, "But I have to remind you."

"You can choose to stay, and the golden apple will grant you eternal life and youth."

"You can also choose to awaken the Holy Sword and turn it into a scabbard. The Holy Sword will make you invincible, and the scabbard will protect you from getting hurt."

"The apples that Avalon has concluded are just ordinary apples. Maybe they will taste better?"

Harry shook his head and said without hesitation: "Then why don't I bring back three golden apples?"

The lady was startled.

After a while, she smiled and said, "If it is possible, that would be the best, but young wizard, many things will not be as perfect as you imagine."

"Make your choice."

Harry looked at her and said nothing.

"To open the passage to the Golden Apple Paradise, the power of oath is needed," the lady explained.

Harry nodded. "Of course. I will choose to give a golden apple to make Avalon grow again and save Geralt and Yennefer."

One...

The lady covered her mouth and chuckled.

Young people always have many wonderful ideas. Have they not given up the idea of ​​getting more golden apples? Of course, reality will always teach young people to grow up.

She raised the jar in her hand, and clear water gushed out, condensing into the sentences Harry said, and each letter was engraved on Harry's hand.

"Go." She waved her hand. "The oath will guide your path."

The words on Harry's arm emitted a hazy white light, pointing to the depths of the room.

He took a deep breath and walked forward.

The house was very deep. There was no lady or decoration in sight. There was only a dark, winding path. Harry walked on it and crossed several small bridges. At the end of the path was a small river and a small boat without a sail.

Harry hesitated for a moment, then sat on it. Without him waving his wand, the boat automatically floated up and went along the river into the distance.

Avalon, the house at the bottom of the island in the middle of the lake.

The lady looked at Harry's receding back with a complicated expression and was about to go back.

With a loud bang——

The stone tablet at the entrance of the house was blown up, and the lake water poured in, along with the rushing water, a handsome young man.

The lady’s face turned horrified: “It’s you!”

"Vivian, my dear friend, long time no see." Voldemort grinned and waved his wand to block the stone tablet. "It seems that Potter has already gone in?"

"You shameless fellow!" the lady gnashed her teeth, "How dare you break into Avalon again!"

Voldemort looked around the room and said cheerfully, "I have been in Avalon for a long time. It seems that Avalon has not recovered after the last time?"

"Where are the Green Knights?"

"After I killed them all, there was no replenishment?"

The lady narrowed her eyes. "You forgot your oath, Riddle! You and Avalon made a promise that from that point on, you would never set foot here again."

"You broke your oath! The oath will punish you!"

"You will die in the frost!"

"Oath?" Voldemort raised his right hand high, and said proudly, "Look, Vivian, I have died once and resurrected again. The power of the oath has no effect on me."

"and……"

"I have even evaded death."

"What oath can punish me?"

The lady waved her hand and said, "You are not welcome in Avalon. Get out, Riddle. I will not be deceived by your sweet words again."

She looked cautious.

Voldemort sneered: "I have learned all the truth from you, Vivian. You may be able to scare Potter, but what about me?"

"Without the Green Knights and the other fairies, Avalon is now unguarded."

"As for you, my dear Vivian, you are just a body of thoughts, how much power do you have left?"

"You are not worth my deceiving." Voldemort raised his wand, "Now let me read your memory obediently, and don't suffer, okay?"

The lady's face changed and she shook the jar in her hand: "Don't even think about it!"

Just as Voldemort said, what remains in Avalon is no longer the fairies themselves, but a residual magical power. What protects Avalon more is the oath of Avalon itself.

She was furious.

Five minutes later.

The pottery jar shattered to the ground, and the lady lay on the ground twisting in pain. Voldemort withdrew the Cruciatus Curse and shook his head: "I said, don't suffer, okay?"

Although his strength has not yet fully recovered to its peak.

The remaining memories, skills and abilities can be retrieved, and have been somewhat restored during the past six months of study.

It's just a body of thought, without the status of a fairy, and is no different from an ordinary witch.

Voldemort is no match for Harry and Dumbledore, and that's just not the case.

"As I am now, even if those green knights and fairies were resurrected, they wouldn't put me in such a mess."

"Let me see what you and Harry talked about."

Silver light emerged from the wand, illuminating his greedy and somewhat distorted face.

"Geralt, Yennefer?" Voldemort whispered excitedly, "Sure enough, Potter knows them."

"Ciri?"

"A powerful person who plays with time and space?"

"I haven't heard of it. Let me take another look... Not from this world?"

"oh?"

He raised an eyebrow, surprised at the news he had received.

The source of Potter's unique and powerful power...

Those unique vertical pupils that were not recorded in any book...

My wait during this period was not in vain.

He whispered, "Potter, I know your little secret."

Just then, Harry took a small boat, swam across the long river, through the fog, through the swamp, and stopped in front of a small island, an island even smaller than Avalon.
