It had been five years since then. In those five years, I had been spending my time to study in high school and then got a Master degree in Mechanical and Electrical Engineering from MIT, Master degree in Laws from Harvard, and a Master degree in Business and Management from Yale. Thanks to a few spells and some bottles of Polyjuice potion, I could do it in such a short amount of time.
When I first asked Sirius about this, he asked me why would I need 'muggle education'?
I answered, "So I could have a better chance at blending in the crowd, Sirius. If I ever needed to hide on the muggle side of the world, I need knowledge. And knowledge is power."
He was convinced enough by my reply and helped me to get around the rules.
The moment I could properly speak – and that was when I was two and a half years old – I asked Sirius to not bring me to any pureblood social life. I did not want to be in the spotlight and or people getting to know me. I also asked him to keep my existence here a secret and asked for Dumbledore's help.
I told him I was aware of what happened when Voldemort attacked Godric's Hollow. And we had been planning for revenge against Pettigrew.
And here I was. Six years old and already dueling my godfather.
"Expeliarmus!" Sirius shot a red light from his wand and I dodged his spell by turning my body a little.
Using wandless magic, I raised my hand in his direction and released a stream of lightning. Sirius had known my magic capabilities for a year.
At first, he was gobsmacked when I burned his ass after he pranked me. I told him that I just willed my magic to appear and obey me.
Test after test he ran for me to test my magic capabilities including occlumency and legilimency.
Just because he was my godfather, didn't mean that I was going to reveal all of my cards. I wasn't stupid.
Back to the duel, he conjured a shield – a protego I assume – and blocked my lightning.
"Not bad, pup. Your wandless magic sure is annoying to be up against, " after he said that he went back to the offensive again.
A barrage of spells was thrown at me with excellent execution from Sirius. I conjured a metal shield out of thin air, raised a wall, and countered with an offensive spell.
An hour later, Sirius was on his back. I overwhelmed him by a large margin after I released my lightning form and my speed just increased exponentially.
"Seriously, pup. How can you duel like that?" he asked me.
"I didn't duel you, Sirius. I was fighting. Not dueling. There's a difference, " I replied not missing a beat. "But, how's it like being beaten by a mere six years old kid, eh?" I gave him a cocky smirk to him.
He laughed hearing my response. "Maybe you could give Dumbledore a run for his money."
Perhaps I could in several years. But now, it was arrogant for me to say I could take Dumbledore on this early. I wasn't delusional.
"In the future, perhaps. He is Chief Warlock for a reason."
Sirius nodded at my words and was getting back to his feet. "Let us have a breakfast, shall we?"
"So, Sirius, I was wondering when can I get my inheritance from my parents?" I asked him suddenly.
"Well, I cannot give you a bull response, can I? Since you have showed some maturity, I guess I will be honest with you," I snorted at the maturity line. "You will get your inheritance when you have come of age. It means when you're seventeen."
"I already knew that part. What I mean is can you do something about it? I want to know what business my parents own, or owned in the past, and how much money do I have, or maybe a manor they left behind. I want to know, Sirius. Can you take me to Gringotts?"
Sirius nodded at me and told me to get ready. We apparated to Diagon Alley to go to Gringotts. As we arrived, we went inside.
"Excuse me. I would like to see the manager for the Potter family," Sirius said to a goblin teller.
"Who are you?" asked the goblin.
"Sirius Black. Harry Potter's godfather, and I bring Harry Potter with me," and the goblin took a look at me.
"Very well. You, get Redfist and tell him that Mr. Potter is here," after shouting the order to his subordinate, he turned his attention back to us. "He will take you to Redfist, the manager for the Potter."
After thanking the teller, we followed a goblin to a room and waited for this Redfist to arrive.
We were not disappointed as he came a few moments after us.
"Greetings, Manager Redfist. May your enemies trembling before your presence. My name is Harry Potter," I introduced myself with the goblin's customary to impress him. "This is my godfather Sirius Black."
"Greetings, Mr. Potter. And may your vault always flowing with golds. I assume you are here for hearing your parents will?" he replied.
I half expected that there was a will left behind by my parents. I nodded at Redfist to proceed the reading of the will.
"But before that, I would like to take a bit of your blood to ensure you are who you said you are. Security measures. I hope you understand."
After taking my blood with a knife, he put my blood on a pensive-like device and the result said I was telling the truth.
The content of my parents will was like any other will in general. In details, I have a hundred million galleons, four hundreds thousand sickles, and twenty thousand knuts – and that was just the money itself.
I inherited Potter manor which was located in somewhere in Manchester, lots of books and gremoires, lands scattered across Europe, and the Invisibility Cloak.
"Can I take full control of all my inheritance before I reach my majority?" I asked Redfist.
"It is possible, Mr. Potter, if your legal guardian permits it," I looked at Sirius and he nodded at that.
"You have my permission."
"Thank you, Sirius."
After several documents and a few signatures later, I had full control of my inheritance.
"Say, Redfist, would you help me in managing my wealth? As I see it is a lot of money and I was thinking of owning several business venue, both in the wizarding side and the muggle side. Of course your help would have several feedbacks to you. How about it?"
"I like you, Mr. Potter. Tell me what do you have in mind?" he smirked and showed me his sharp teeth.
And then we spent several hours in Gringotts discussing my business plans.
First, I wanted the Potter manor to be renovated to be more modern. I gave him a design of my liking with my device which could be used like a projector thanks to my capabilities in technology combined with runes. Sirius already had seen my inventions. I have several more at Grimmauld Place.
Next, I wanted to invest in car industry, race broom industry, the food industry, and fashion.
"Redfist, do you have any reports of the transactions from my trust vault in the last five years?" I asked Redfist. I was being paranoid because Sirius never told me about the financial. Not that I distrusted Sirius, but I distrusted Dumbledore.
"Here says, there were five transactions in the last five years…." he explained long and in details about the report.
I was right. Dumbledore wasn't trustworthy. He stole my money from my trust vault. And I would make him pay. After hearing the report, I told Redfist to not prevent anything or Dumbledore might be suspicious. But I told him to stop pouring money into my trust vault as I had full control over the main vault.
"One last thing, Manager Redfist," I said.
"What is it, Harry?"
I smiled at him and continued, "I read about goblin and their expertise in making weapons. Could you perhaps, help me to have a goblin-forged sword?"
"Before I say anything, may I ask you why?"
"Voldemort is not dead yet. And he certainly will come back. He went to kill me five years ago, and he certainly will when he comes back. I need to be ready for him. Please," I asked him and finally he agreed to it.
My weapon would be a thin sword. Like a rapier but it could be used for slicing the enemy up like a sword. And with that concluded our business in Gringotts.
After Gringotts, Sirius and I were going to eat. We decided to eat in the muggle London. We went to an Italian restaurant.
And then I went to a cloth store to buy several shirts, pants, and a suit. I didn't like wearing robes like a pompous, spoiled pureblood kid. I liked to go with style.
We finally went back to Grimmauld Place and had a sleep.
