The next 3 days went in training and recuperating. I have also grown a couple of inches and have started to lose my skinny frame. A house elf also spies on Dursleys all the time. It seems either they have not noticed my absence or are happy with my disappearance but atleast they have not spread the news it all around the neighborhood. Figg and ultimately Dumbledore wouldn't notice anything strange.
And today, I am finally going to teach the Dursleys a lesson. I asked Tobby to teleport me to the edge of the backyard of Dursley's House and follow me invisibly and silently inside. I was not worried about Dumbledore finding out about it because Dumbledore didn't know about Dobby in the canon.
I entered the house through the backdoor and entered the kitchen where the Dursleys were having breakfast. Seeing me entering the kitchen they were shocked and angry.
"Finally decided to return you ungrateful Freak. What were you thinking that someone is gonna help a freak like you. You should be grateful that respectable citizens like us agreed to take you in and you dare to run away. Now get inside your cupboard and forget about any food for a week." Vernon said.
"Yeah, such respectable citizen who involve themselves in slavery and make their own nephew a slave, starve him, gave him scraps and your leftover to eat and you want me to be grateful to you, you hypocritic, obese, son of a rhino." I said.
Hearing this Vernon leapt from his chair and charged at me like a bull, but I was ready and already had my wand in hand and fired a Stupefy at him. A streak of red light hit him, and he directly fell on the floor. Seeing him fall like this Petunia screamed as if she saw a murder happening, which according to her is the case.
"Shut up you dumb, petty, jealous women. He is only unconscious but if you don't shut up, he will surely die." I threatened her.
After making some distance between me and Vernon I fired an Enervate at him. As he gained consciousness and started to get up, I fired a banishing charm at him and then tied all 3 of them in rope using Incarcerous.
"Now, there will be some changes in this house. First, I will be taking Dudley's second bedroom. Secondly, I will not be doing any chores other than gardening and that too when I feel like it. You will not have to feed me, my helpers will bring my food directly to my room. You ignore me, I ignore you, but I don't trust you so for good measure..." I said and fired three streaks of light at them.
"This is a curse, if you harmed me directly or indirectly, you die. If you kill me directly or indirectly, you die. You torture me, you die. You got the picture, good." I bluffed. Then I freed Dudley from ropes. "Go and clean that room. If I find it even a little bit dirty, you wouldn't like the result." Hearing this the cowards ran to the room as fast as his legs allowed him.
"Now you both will be acting as you normally do. I wouldn't be here for most of the day so you will not have to see me, and I will not have to see you and make sure that little whale you call son, and his friends don't bother me. Nod of you understand" I said, and they nodded so fast that I wouldn't be surprised if they sprained their neck. "Now get to your work." Ah, it feels so refreshing to finally be able to let out those bottled-up emotions of Harry, but I am not finished with them, right now I need to maintain appearance but after that I will ruin their life.
I was expecting another attempt to attack me by Vernon, but it never came, and they left to do their work while looking completely scared. Soon Vernon left for his work and Petunia started doing household chores. As for why I agreed to do gardening, so that Figg doesn't suspect anything. Then I left for the local public library, it used to be my safe heaven because Dudley and his gang would never come here so the librarian was not surprised to see me. But this time something was different I could see some books glowing and I figured out they were likely Skill Books. I went to one book which was on science and picked it up and soon a screen popped up.
Skill Book Found!
Science Lvl - 17
Do you want to absorb the knowledge in it
Yes/No
I thought 'yes' in my head and suddenly a light itching started in my head, and I could recall everything in the book perfectly, but it was like I tallied some notes. I was very thankful that it didn't destroy the book and decided to read the book just to check if my assumption is right and I was proven right. There were many little pointers and example that I couldn't recall from the knowledge I absorbed but are mentioned in the books.
I also noticed another thing my Science skill suddenly increased to Lvl - 32. I thought about it for a minute but then realized, my knowledge of science will of course be better than a 13-year-old because of my previous life memories and it was likely due to that. So, most likely my other skills that I know about will also increase but I didn't focus on that and started taking out skill books from the shelf.
After that I spend my whole day in the library, absorbing the books, some books on history, science, english and, mathematics became useless. But the books on different languages, advanced books, books on martial arts, and some other were very helpful. I also made a list of these books to reread them as I know absorbing it wouldn't make me know everything in it. And I learned
Latin Lvl - 5
French Lvl - 2
German Lvl -1
Scots Lvl - 2
Scottish Gaelic Lvl - 3
Irish Lvl -3
Karate Lvl -1
Kung Fu Lvl - 1
Muay Thai Lvl - 1
My history, science, mathematics and english skill also increased with the advanced skill books, originally meant for colleges and university student but still history is the slowest of all of them, most likely because the books mostly talk about UK only and not about the world. I only left the library after I started to feel hungry and saw that its lunch time. I went to Privet Drive inside my new room which has been cleaned now and asked Tobby to bring my lunch along with my potions.
After having lunch, I again went to the library and spent the rest of the day increasing my muggle skills. At night I went back to the Potter Manor and have dinner and started reading some Magical Theory and Wizarding History, which gave me skill Magical Theory and Wizarding History. After that I went to sleep.
