Frowned Upon as the Child of a Prostitute, the Seventh Prince Becomes the Strongest Wizard after Working Hard since Infancy

I managed to live my life despite being treated coldly, and I found myself at the age of five.
What I’ve been doing for the last five years is not just idly drinking milk f, but learning , examining and training myself in various aspects of this world to protect my mother, Sonya and myself.
As I said before, magic exists in this world.
It’s a very intriguing concept that doesn’t exist in the world I came from.
Magic requires the consumption of magical power in the body to activate, and its strength is determined by the amount of magical power in the body.
This takes me to my current position of being unfavoured by the Emperor, due to having little magical power.
The person who will be the next Emperor must be smart, charismatic and a pure fighter.
I was found to have almost no magic power as a baby, so the chances of me becoming a great wizard in the future are almost nil, so people think that I will never become the next Emperor, and I am treated coldly along with my mother.
But I didn’t plan on settling for my current position.
I had already grown to love my mother, and I didn’t want to end up in a power struggle in the future only to die without a fight.
So I was going to do the very best I could to protect my mother and myself.
I also had an interest to master magic, since I was reincarnated into a world with magic.
In any case, magic cannot be used if there is little magical power.
So I first tried to increase the magical quantity in my body.
I had no prior knowledge of this world and had to do a lot of research, but after a lot of perseverance, I found that after using up all of my magic power, when the next time my magic power recovers, it increases a bit, just like super-recovery after muscle training.
However, this super-recovery of magic power is accompanied by spectacular suffering.
To be honest, it was insanely painful and hard, but, there was nothing else to do, so I emanated magic every day, and then I suffered and super-recovered, gradually increasing the magical power in my body.
Thanks to my efforts, the magic in my body increased rapidly and unnoticed.
That’s how I was able increase my magical power, and I gathered knowledge about this world by reading various books.
There was a huge library in the rear palace, where books on everything from politics and agriculture to religion, magic and history were stored.
The Prince’s privilege allowed me to go in and out of that library as I pleased, and I read those books and accumulated knowledge in a desperate attempt to survive.
