In the dark cell, Xu Fang saw Sirius again. At this time, Sirius was no longer as handsome as before, but curled up his body and had a stubborn beard. He felt like he had lost weight in just a few days. He looked extremely haggard, his hair was messy, and he didn't know how long he ignored it. His clothes were wrinkled, and his whole body exuded a decadent atmosphere.

The dementor who was in charge of guarding the criminals had been driven away. Xu Fang was very satisfied with the smart and capable female magic minister and was very sensible. When encountering difficulties in the future, Xu Fang didn't mind helping him.

Through the iron railing, Xu Fang looked at his cheap brother and said, "It's so embarrassing! My dear brother! I originally wanted to find an opportunity to meet you and your mother, have a good chat, and ease the relationship, but I didn't expect you to be caught here! How does your life in Azkaban feel?"

Sirius opened his eyes and looked at Xu Fang with annoyance and said, "Hmph! What's the point of seeing that stubborn old woman? Did he be scolded and sarcastic by him like last time? I don't want to seek any more suffering."

"Who can you blame? You ran away from home for several years and haven't seen our mother once. Of course, the old lady was so angry. Is it smelly? If you vent your vent, you have to be honest. What's the result? If you say a few words, you will turn around and leave."

"Who made him speak so badly?" Sirius said, but his tone had softened.

Xu Fang's words also made Sirius realize that he ran away from home without caring about his mother at all. It was indeed a bit too much. He finally made up his mind to go back and visit his mother.

But the old lady was so angry that after meeting, the sky was furious and the two stubborn people almost started arguing. Xu Fang finally persuaded them to calm down, but Sirius could not bear the guilt and turned around and left, and then never went again.

Xu Fang didn't want to continue to get entangled on this topic, and asked in a tone: "Okay, let's not talk about this, let's talk about your affairs. Tell me, what's going on? Why do everyone say you betrayed the Porter couple?"

Sirius was silent for a moment, with a hint of pain in his eyes, "There is nothing to say, it's what I did, otherwise how could he be scraped here? Everything is my own worth, so don't ask."

Xu Fang sneered, "Is this really the case? Why do I see guilt and regret in your eyes? Since you betrayed the Porter couple and let them die at the hands of Voldemort, what are you guilty of? What are you guilty of the Porter couple's death, or the dozen murdered Muggles."

"Enough, stop talking. You don't have to worry about my affairs. Get out of here, I don't want to see you again!" Xu Fang's words directly stimulated Sirius, with a ferocious look on his face.

"Of course I will leave, but I think there are some things that should be made clear. The Potters left behind a child, Harry, are you still his godfather? If he is in danger, will you want you to save him?"

"What Harry is in danger? What's going on? Explain it clearly!" Sirius was anxious, rushed over and grabbed the iron railing, staring at Xu Fang and asked.

"Don't worry, there's no problem for the time being, but it won't be sure in the future. You also know about the Horcrux. You should understand that one day that person will make a comeback. Who do you think he hates the most? Who is the one who wants to be eliminated first?"

Sirius's face changed a little, and he immediately understood what Xu Fang meant. The person Voldemort hated the most was of course Potter. Now his friend James Potter and his wife died, leaving only one child, and he was the one who defeated him at his heyday. The prophetic savior, all hatred was concentrated on one Harry. In the future, Voldemort would be his primary goal.

"If Harry is really a bit dangerous, I will save him even if I fight for this life. This is the debt I owe and will never be paid."

"But with your strength, even if you fight for your life, you can't fight against that person. How about it? Do you want strength? There is a chance now."

Sirius suddenly raised his head, looked at Xu Fang and asked, "What do you mean by this?"

Xu Fang did not answer, but stretched out his right hand and pointed his index finger on his temple. It seemed that something was pulling out of his brain. A fluorescent light flashed between his fingers, and he reached out to Sirius' forehead.

Sirius felt inexplicable, but he felt that Xu Fang would not harm him because he was already miserable enough, so there was no need to be such trouble. If he really wanted to kill him, it wouldn't matter. Death may be a relief for him, and he did not avoid him. Xu Fang's fingers pointed on his forehead.

boom!

Sirius felt something exploded in his mind. He couldn't help but check it carefully and found that there was a memory in his mind. It was a unique secret technique of cultivation that could absorb spiritual energy and strengthen himself. It was very exquisite and could not help but look at it in detail.

Xu Fang's smile on his face became more and more intense. This method of teaching and practicing the secret technique was to create it based on his divine thoughts, extract his own memories and present them in the minds of others.

Xu Fang glanced around from the corner of his eyes, and occasionally saw dementors shrouded in his cloak and exuding a terrifying aura passing by. In the eyes of others, the terrifying monsters may become the nutrients and food for his cheap brother in the future.

Dementors are magical creatures between illusion and reality. With human happiness, they show that they absorb spiritual energy, so there must be an original spiritual power. Since they can absorb spiritual energy, they can also be absorbed by others in turn. The key is to find the right way. The secret technique taught by Xu Fang to Sirius can do this as long as they practice to a certain level.

In the eyes of others, Azkaban is the most terrifying place, but in Xu Fang's view it is a paradise for cultivation. With many dementors providing mental power, Sirius' cultivation speed will be faster than expected.

Seeing Sirius who had gradually become better and entered a state of cultivation, Xu Fang stood up and strode out. His purpose had been achieved, and it was meaningless to stay.

Goodbye, my dear brother, when will the next time we meet? Twelve years, or thirteen years later? I hope you have been reborn by then and stand at the same height as me. Endless regret is your motivation for cultivation. Only when you are strong can you protect Harry. Work hard and don’t let me down!

When Xu Fang left the Ministry of Magic, he had an additional document in his hand, which was a statement of the return of the Black family's ancestral home at No. 12 Grimo Square, London.

When Xu Fang returned to the safe house and handed the documents to the cheap mother, the old lady almost burst into tears. She packed up her things without saying a word and returned to her ancestral home that day.

However, the ancestral home was burned out in an unexpected way. Although Xu Fang's fire was destroyed by the Death Eaters, part of it had been burned out. Of course, the people from the Ministry of Magic would not pay for repairs. They just cast the Muggle Dispel Spell to prevent people from getting close, so they ignored it.

The child was left to the cheap mother to watch. Xu Fang and Jenny worked together and repaired the house with magic. They first organized the bedroom and kitchen, and then took a week to repair the old house.

Xu Fang used defensive magic to the house again. With Xu Fang's current strength, he was close to Dumbledore, and the reblessed protective magic was not weaker than before.

On this day, Xu Fang repaired the last damaged place in the old house. After blessing magic, he suddenly had an idea. When he was still very weak, he almost killed Voldemort and dozens of elite Death Eaters with the advantage of his ancestral home. If he created a unique space, he could move at any time, summon at any time, set up some mechanisms in it, and change it to the most beneficial state at any time, or bless some magic to attack, can he enhance his own strength?

Xu Fang couldn't help but think of many magic towers in fantasy novels. Can you also make one of them? If the magic tower is too big and difficult to summon, you can make a magic tower that can be assembled freely, which can be decomposed into small pieces, and the effects of restoring the shape and changing shadows are added on it. Summon it when needed and quickly assemble it.

Xu Fang remembers that he had read some ancient magic runes in the book. When burning them on objects, they could also achieve magical effects. If they were made into parts and then burned the magic runes, and countless parts were assembled together, how far could they reach?

However, if you want to do this, there are still problems to be solved. Xu Fang has limited magic runes and needs more knowledge reserves. With the Black family's collection, it seems that you have to find a way to go to the library of Hogwarts Academy. In addition, to reach such a magic tower, you still need super computing power. No matter how smart Xu Fang is, he cannot calculate the required data by himself. Xu Fang made up his mind to create a super computer and cooperate with magic methods to create the magic tower in his mind.

This is a long-term plan and cannot be completed overnight, but Xu Fang is confident!
