Harry Potter But AU?

Luna's POV

Luna was truly happy she got such a friend like Harry, he was just like her with his passion about magic, in fact he told her the day before that he thinks that while Hogwarts was the founders greatest gift to the magical kind, it was also their greatest curse, as while they made sure knowledge won't be lost, and that everyone have education, they also made sure that the magical people would have almost no ambition at exploring the limits of magic as that think after finishing school they know almost everything there is to know about a subject and if they go become a master in a subject, the best they do is create new things which are based on old things, without innovation.

He then proceeded to tell her about all the amazing things muggles accomplished in the last three hundred years, which brought her to do what she is doing right now.

Finish her homework quickly before Harry returns from wherever he has gone to, as he brings her muggle books about animals, math and Science.

Draco's POV

As he walked into the classroom with his new student, Draco still was thinking if his godfather is trying to punish him or reward him by giving him the job of teaching Potter.

On one hand, he has to spend two hours every weekend with Potter in the potions classroom instead of training to beat him as the new seeker of the Slytherin team. Yet, as his godfather has promised to give him one private lesson a month as long as Potter's grades in potions get better, he agreed.

"What are you doing here?!"

As Potter's yell brought him out of his musing, a small smile was forming on his lips as he remembered his godfather told him he can take 30 points a lesson from the Gryffindor as long as there is good reason.

"5 points for yelling on your new teacher!"

Yes, definitely a reward.

Harry's POV

Harry finished his blacksmithing lesson really happy, his teacher said his swords are almost good enough to start working on sabers, s and according to what he told him, after he finish sabers, he would start working on defense gear, which is one step closer to his goal of learning the goblins magical part of blacksmithing.

But right now he has another lesson he needs to be in, a lesson where he is the teacher and the student.

As he walked into the classroom he and Daphne agreed on meeting, he saw her sitting next to a table with lots of paper and a hovering automatic-writing Quill.

"So, how do you want to start this?"

"I would first teach you. As I told you, the art of Occlumency used to be something everyone was taught in school, which made it an identical thing in everyone's mind. But with the school teaching being canceled and the pure-bloods unwilling to have their children's mind unprotected they started using variations of the art which are easier to teach one on one and improve them until they become unique for every family.

My great grand father was the one who perfected my family's technique which is called 'fire in a winter storm'."

When Harry heard this, he couldn't help but blurt "Chūnibyō?"

"You heard about this terrible disease?"

After which her explanation about the Occlumency technique stoped while he explained what 'Chūnibyō' meant, and only after five minutes they returned to the main subject.

"My family's technique is focused about the basics. According to my father, most Occlumency techniques he saw while trying to read people minds which aren't only beginners aren't focusing on defense but more about tricking the opponent by making them think they managed to get past the shields while the real shields are the memories you don't mind them seeing.

My technique works by making the defense impenetrable s as make a three ways defense.

The first defense is the same as everyone else, clearing your mind, you need a clear mind to feel the penetration into your mind and to build your defenses, my family went even farther in that by creating a mind fire as a way to easily clear your mind.

The second defense is after you create the basic shields with your magic, you change the properties of the magic to earth and ice, thus creating an enormous ice wall which you make bigger and thicker in time and magic.

The last defense is using the fire from the first defense to break the ice from the second while converting your magic in to wind to create metaphysical storm that would prevent people from being able to find any memories as they are unable to see.

This defense is an active defense that constantly cost magic and destroy your second defense so only when you know someone is attacking your mind your second defense can't win against you should use it, a side affect of activating the last defense is making hurting both you and your opponent so use it as only last defense!"

After that he asked her couple of questions to clear some doubts and then started his part of the deal.

"Lets start by establishing facts.

1) the curse is something that has being passed to your sister by one of your parants, correct?"

"Yes, but I already told you that."

"I am trying to explain to you my idea, be quiet. So if it is a curse that is being passed to you and your descendants calling it a blood curse is incorrect as it make you believing it is like the blood boiling curse, a curse that infects the blood while actually it is a bloodline curse, a curse that infects your DNA.

Now, a DNA or Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids."

"Yeah, I have no idea what you just said."

"Basically, every thing in this world is built from atoms- things so small they are impossible to be see without really advanced muggle technology."

"Or magic, right?"

"I haven't yet found magic that can let you see atoms, but I guess it's possible."

"So how do you know of it?"

"I grew up in the muggle world."

"What? You and Marcus Potter grew in the muggle world????"

"No, just me. The Potters left me in the muggle world after Marcus became known as the boy who lived. Can we continue?"

"....sure, let move past the fact the Potters abandoned their one year old heir," she said cynically, "but can you explain in a way a magical person would understand?."

'Sigh' "Think about every person in this world as a spell, and if you are an ice creating spell then your perents are a water creating spell and a freezing spell. The DNA is basically the Arithmancy you do when you try creating the spell. Understand?"

"So why is there any difference between my sister and me? After all we are from the same parents."

"That's where it becomes more complicated. First of all, both of your parants DNA - let's call it 'spell sequence' isn't really an easy spell like water creating. It is more like an animagus creating potion or the Fidelius Charm, plus you only get half of their 'spell sequences' from each, making it so you are a combination of both while even this half is mixed, so in the end you become a unique creation."

"So if this curse is in my mother's 'spell sequence' there is only 50 precent chance I would get it and while I got lucky my sister didn't?"

"Pretty much."

"so as we know where her curse is from, if we can find exactly what part of the 'spell sequence' can we change it?" She asked with eyes full of hope.

"Well, I wouldn't know how to, as this isn't really a 'spell sequence' where removing parts of the spell just prevent it from activating or activating weird, it is your sister body, and if her DNA is destroyed, so is she. And if you play with parts you don't understand you her body can change in unpredictable ways. Eye color, muscle growing outside her body instead skin, and gander changes are the lightest of the side affects of messing with someone's 'spell sequence' plus the fact you would have to change all of her 'spell sequences' which she has billions of and keep growing without destroying her body.

But if you manage to do all of that and avoid other problems I haven't thought about, you might manage dispelling the curse."

He was so into analyzing the problem, he hasn't noticed that she started crying in the middle of his explanation. So when he looked up he felt so bad he couldn't help but give give advice.

"I know it sounds impossible, but you shouldn't look at the entire road ahead, you should just keep looking on the next step.

The first thing you need to do is find a way to see the 'spell sequence' and translate it to an understandable language so you can find where exactly is the curse in it. Just work in steps."

"Please help me!!!" she said after calming down. "I can't do all on this on my own and my group would never agree to work on something that is based on muggle knowledge, hell, if I wasn't willing to do everything to save my sister, I would have stoped listening after you told me it was a muggle thing.

I could barely understand your explanation when you dumbed it down to me, how am I supposed to learn enough to even start experimentations before my sister dies?

I would give you anything, just please help me!"

Harry knew it was wrong to use a desperate woman, but this was a chance he couldn't pass.

"I am sorry, but I really don't have the time, if there was a way to make more time in a day I would agree..."

"So if I find a way to give you more time, would you help me?"

"Yes"

"Give me two months."
