HARRY'S POV
the next two weeks were full of hiding for Harry.
With the exception of COMC, workouts and meals, Harry stopped leaving the ROR except for going to the chamber of secrets when his past self was using the room.
Something that did wonders to his progress in everything.
His runes reached a total number of 43, which, because he focused on specific ones meant he was halfway there to create a container of magic with only his runes, and start mass producing them.
His forging skill improved, making him able to create stronger effects on his creations, and he even improved in the layering method, letting him put another intent into his creations, reaching a total of three.
Even his medical studies progressed with speed he wasn't used to, with the speed right now he believes that by the new year he would finish the sixth year.
Yet the thing he was proudest of was his research.
With Daphne giving him the blood samples of Nymphadora Tonks, and Remus getting him the books, diaries and journals from the libraries of both the Potter family and the Black family, especially the Black family, Harry managed to figure out the how the metamorphmagus' ability work, even if he still didn't find a way to turn one into one.
He started by researching the blood, he found out it looked just like regular blood until you put pure magic in it.
When you put magic in regular blood, the only thing that happens is that the white blood cells become a little bit stronger, making them more resilient to Bacteria, which was why the magical world has no regular sickness, instead, it has Bacteria that evolved with magic to attack those specific cells.
On the other hand, when pure magic comes into contact with the cells of a metamorphmagus, it has two effects.
On the cellular level, they become a lot like Stem cells, as if they are being reprogrammed.
He also find out that if you keep the pure magic long enough in that state, it will return to be a full time stem cells, which led Harry to the conclusion that metamorphmagus would die from that.
The second effect was on the DNA level.
Not only does the ability change your cells' shape, it also change your physical DNA, at least in the specific location that magic is being poured to, meaning each time metamorphmagus changes a body part, they use the same method he use for transfigurations.
Not cognitively, they don't think of the molecules, the atoms and the cells, Harry didn't believe they could, as even he, with his mind and eidetic memory had it hard with thinking about the different things that made an object what it is.
No, they did all of that subconsciously, and more importantly with their belief.
Their transfigurations, and probably all their magic was almost entirely based on beliefs, and if a journal that was in the Black family's library is true, then while the Ollivander family was one of the oldest professional wand making family, the first one to create a wand was a Black, specifically one that was a metamorphmagus by the name of Felix, who used the way his body works by his wishes, without any needed knowledge, to help his younger sister cast spells by making her a wand with most of his hair changed to look like a stuff, though he didn't have enough mass to make a big one, before cutting it.
While Harry didn't know how much of it is true, the fact that metamorphmagus work with their belief instead of magic made the reason why there was never anyone who was both metamorphmagus and animagus.
While metamorphmagus' ability is based on belief, animagus' is based on knowledge.
To be able to change into the animal, in addition to the potion or ritual that was needed, you also need to know your animal, physically, which is the reason most people don't become one, while making the potion isn't easy, it is the research that makes most wizards and witches give up.
This gave Harry an idea that can be used to cure Astoria, but for that he would need Nagini, you know, as a guinea pig.
While Harry was pleased with his progress and the way he use his time efficiently when not playing music with his friends, the school hasn't shared his sentiment.
The teachers more then once tried to force him to go to class, and when that didn't work guilt trip him into going.
While to the teachers he liked for their enthusiasm or their way of teaching he explained he need to learn faster then class, to other teachers who felt the need to take points from him (He rolled his eyes when he heard that), he hasn't said a word to.
Another group that didn't seem to like the way he act as the champion of Hogwarts was the students, who started enthusiastic, with Slytherin taking charge and promoting him as 'the real Hogwarts champion' and by saying that 'in Hogwarts we don't need a seventh year to beat other schools', with Ravenclaws and Hufflepuff joining in, and even Gryffindors cheering sometimes.
But after a week of him hiding from the headache that the students was causing him, even missing the wand weighting, which made Rita skitter trash talk him in the daily planet, the talks changed into sneers and jabs.
Calling him a snob and saying that at least Marcus is brave enough to walk in school was only the nicest things he heard from them.
Harry really didn't care much, he wanted to study, research and hang with his friends, he didn't care for anything else.
As for ruining the Potters? No matter what, it would only be temporary, the only thing that ruins a person forever is death... and maybe torture.
