Harry looked at the golden "Sun Golden Sutra" and emitted dazzling light. He separated the sea of ​​fire and hugged Hermione to the bottom of the black dragon. The black dragon Malfoy said in disbelief: "Harry, I really underestimated you. I didn't expect you to awaken the power of the "Sun Golden Sutra", but that useless... both scriptures will eventually fall into my hands."

Harry raised his wand: "Malfoy... fell to the ground!"

The light emitted by the Sun Golden Sutra lingers on his magic wand. The power of the spell turned into a ray of sunlight that had just begun to bloom in the sky and the earth, and shot towards Malfoy's heart. The rising sun that stopped rising under the power of the "Black Sutra of the Undead" suddenly shone brightly, tearing through the dark sky caused by the magic power of the "Black Sutra of the Undead".

At this time, Malfoy shouted in disbelief: "This... is impossible!"

He manipulated the power of the "Black Sutra of the Undead" in vain, trying to stop the power of the black magic that completely restrained him, but everything was in vain. Just as Malfoy's heart was hit by a spell and his mind was dizzy and shaking, Harry's heart that had already let go suddenly raised, and the man in black who handed him the key to the "Black Sutra of the Sun" appeared behind Malfoy again.

"Avada Sauvigny!" The man in black robe sent a life-seeking curse hit Malfoy.

"No!" Harry shouted.

Malfoy's soul floated up, and he stared at his body blankly. The soul looked at the man in black robe in confusion, and suddenly seemed to understand something. He shouted something at Harry, but the soul had no sound. The most important thing was that his soul returned to his destination and disappeared into the air.

When Harry returned to school, there was no one on the observatory. When he returned to the principal's office, Harry found Dumbledore staying there. He held Hermione and wanted to tell the old man everything, but Dumbledore stopped him. He said old: "Harry, don't tell me, I know everything..."

He looked at Hermione's unconscious 'corpse' and put her down and let her lean against the chair in the principal's room. He whispered to Harry, who wanted to say something: "I know Malfoy is dead. I also know that Granger will be back in the future... But Harry, promise me that if one day you have to kill me, don't hesitate..."

Harry couldn't understand: "Why?"

"That was a very difficult and heavy burden, and I shouldn't let you take it." Dumbledore shed tears, grabbed Harry's hand and said firmly: "But promise me that at that time, don't hesitate...must...kill me!"

Harry was going crazy: "Why? Hermione said that in the future I will kill you, Ron, Snape... It's not difficult for me to understand, but why should I force me like this, Professor? When Hermione told me, I felt that I would never do this in my life, and I couldn't become that person."

"Because it is impossible... you have to do this even more." Dumbledore said in pain. He grabbed Harry's hand and trembled slightly, and repeated: "Promise me... promise me."

Harry was almost driven crazy, but at this time, he saw Ron, who had grown up, with red hair still in a mess. He pushed the door in, his face full of tears: "Harry!" Ron turned around and hugged him, but Harry was a little helpless. Ron, who was already a big adult, hugged the thin Harry, and the picture was a bit funny.

After Ron calmed down, he said to Harry: "Promise Professor Dumbledore, and, when necessary, when you know the time... don't show mercy when you attack me."

"This is impossible..." Harry pushed Ron away and replied excitedly: "I can't do such a thing."

"But you have to do that," Ron replied. "If you don't do that, we'll disappear because the world is a single-trace universe, and then you'll forget who I am now and Hermione. So, for our good, you have to kill us."

Harry woke up and said in horror: "So, the shadow who killed Malfoy..."

"Not him!" Dumbledore's eyes showed deep guilt, and he sighed, "Don't ask, Harry, you will understand in the future..." Dumbledore looked at the watch in his arms and whispered, "I don't have much time! Where is you?" Ron returned, "I have set aside some time, it's still early to my turn."

He hammered Harry's chest and smiled, "I want to have a good chat with Harry... You are too young now! Snape doesn't want to come here... but I think you won't be ruthless when you kill him."

"Don't say something so terrible." Harry said anxiously: "What the hell happened."

"I can't tell you!" Ron hesitated. At this time, Dumbledore suddenly said to Ron: "You can't take up too much of his time... Go quickly! Go back and wait, I think 'he's something to say to you."

Ron showed a complicated look: "I misunderstood him for a long time..." Ron turned his head and said to Harry: "If 'I' misunderstood you and scold you in the future... I want to say sorry now... I have already said it in advance. So you can't blame me."

After saying that, Ron left without looking back. Dumbledore pointed at the time converter in Hermione's chest, and Hermione's body disappeared in front of Harry's eyes. Dumbledore hurriedly said: "Harry, remember. We are all behind you, and all sacrifices are valuable!"

After saying that, he pulled Ron and left without looking back, regardless of Harry's shouting and chasing behind him.

Chen Ang and Dumbledore were watching all this secretly. Dumbledore was a little excited. He asked: "In all of this, Harry is always the one who has experienced the most suffering and confusion, and he is also the one who sacrifices the most. Do you have to do this?"

"You have no choice... in this world, Harry Potter is special. Only his time and destiny can break the control of that existence on your world, so... everyone must die in his hands. Explain your destiny... in the words of Eastern magic - that is luck. Give it to him, and he represents this world, creating the Mobius time cycle."

"For special reasons, this world is a single-line universe, and there is no parallel world. The well of eternity is the mechanism hub of the time cycle of the future world. It is also the only key to constrain the time, destiny, cause and effect of this universe and fix time."

"I borrowed Morgoth's extraordinary power to create the future, so that you and Hermione and Ron will return to the present, as the first cause, make Harry the next Dark Lord, the grandmother paradox of creating the single-line universe on the timeline, so that the universe under the control of the existence of the Lord God collapses into a circular universe, and can break the circular fate in the next cycle, expand the single-line universe into a multiverse, and open the circular world line into a spiral world line."

"In the anchor coordinates of the Lord God, Harry is the most important one, and Ron and Hermione are immediately followed, followed by you, Voldemort, Snape and other professors and wizards. In order to make this world break free from the anchor of the Lord God, these coordinates must be involved in the time loop, but to prevent the expansion of variables, the anchor coordinates must be confined, that is, when the Lord God interferes with the world, there can only be Harry's coordinates, and you must die!"

"In the future I created..." Chen Ang's eyes turned to the mysterious man in black. He took off his hood. If Harry was here, he would have been shocked - the lightning scar on his forehead, the eyebrows and eyes that were particularly similar to him - clearly he was when he grew up.

"The future Harry killed Ron, traced Hermione's time converter to the present, he handed over the 'key' to the present Harry, and then killed Malfoy, who is the fourth Dark Lord. In the future, he will walk as the fourth Dark Lord. When every Harry has no evidence of being absent, he will remove the anchor points at the edges one by one."

"And then when Harry is now in his seventh grade, find a chance to kill you in front of everyone's eyes."

Dumbledore nodded after hearing this: "Then Harry goes back to pursue the real murderer. In this process, the future Harry will risk the name of Harry now to kill his friends and relatives. Finally, when Harry finds him, the two will have a fateful duel, letting the current Harry kill him. Complete the cycle."

"At that time, the future Harry will be responsible for telling him everything, and I will come to the future to supplement it in advance."

Chen Ang smiled and said, "Then... let's go!"

The two tore open the space and come to Hogwarts' temple, where Harry held a magic wand and looked at himself lying on the ground in shock. Harry was so shocked that he was not even more surprised when he turned around and saw Dumbledore.

"Professor?" Harry was a little confused, and he opened his mouth to ask something.

But he quickly calmed down because he saw Dumbledore seemingly younger, especially the phoenix feathers on Dumbledore's chest. He looked dazed for a moment and hesitated: "The professor of the past? Was it the professor on the day Malfoy died?" He turned to see Chen Ang again and whispered: "Morgoth!"

"Yes..." Chen Ang said calmly: "We are here to explain all this."

Dumbledore told Harry the truth about the world, and he whispered: "This world is a cage, a book that cannot be read back and forth by an existence that cannot be described. For freedom and dignity, and to save the world, we must sacrifice for it." Dumbledore showed Harry the memories of those reincarnations doing their own thing in this world, and he said to Harry sadly: "So, we have everything on your shoulders."

"To break the control of that existence, we must destroy the anchor point, and use a new force to take the world away from him, so we use you to destroy the anchor point with the help of Morgoth."

Harry asked, "What is the anchor?"

Dumbledore said silently, "It's us...so, you have to kill everyone, your friends, your loved ones, everything we care about until all the anchors are concentrated on you, and then you will complete the cycle of time."

"When you put all the anchors in one, we will use the power of the Well of Eternity to send you back to the day you killed Malfoy, you need to hand over the key to yourself." As he said, Chen Ang threw the key to Harry "and then kill Malfoy, as the fourth Dark Lord, kill those who must be killed by you, including Ron and me, Snape and your mother."

"If you do this, there will be a paradox in this world - when everything is over and the Lord God wants to restart, it will find that it cannot do this, because if you don't let you go back in the past, then you will die under Malfoy that day, and no one pretends to kill Dumbledore, and you will not become the Dark Lord. At that time, the power of this time cycle will force him to anchor, that is, you."

"Put back to the past - and if you do so, the world will be locked in an infinite cycle of time. There is no future, and whenever the Lord God wants to end the world, it will automatically restart."

Harry was completely stunned. He smiled at his future 'self', and his soul gradually disappeared - he couldn't help but fall to his knees and burst into tears. Dumbledore said in the same grief: "But this is the last time... Harry, this is the last time."

"At the moment, we can break the cycle and make this world... let the future become free. We will become the stone stuck in the gears of the Lord God. At our cost, let everything be left uncontrolled by the Lord God. The Well of Eternity will fix the time of this world for the seven years you went to school, and the time continued to cycle, but the wizards and muggles in this world are free. They will find that the material world is only updated every seven years, and their souls and will will not be fiddled with."

"And... Harry, the souls of all the people you killed, are preserved in the Sun Golden Sutra, and at that time you can resurrect them and give them complete freedom in the new world!"

Harry wanted to say something, but finally hesitated for a moment, shook his head and said, "I understand! When they are resurrected, let them forget this memory!"

Dumbledore nodded silently, Chen Ang and him returned to the normal timeline. They walked in the corridor of the principal's room. When Harry rushed out, he saw Dumbledore, as if he had seen a ghost. He stammered: "Professor, you are not from there..." His eyes were on Dumbledore's phoenix feathers on his chest, and for some reason, he remembered it firmly.

On the timeline, Chen Ang stared at the single-line universe that had been connected into a ring, watching it slowly separate from the cumbersome system of the main god, and suddenly laughed: "Another laboratory has been built... I always pry the corner of the main god like this, I'm afraid it will turn against me!"

"It's time to return!"

In the magic world, a white light rose from Hogwarts and disappeared into the sky.
