A Magical Loser Gets an Ancient Magic Book and Reaches the Top?

In this world where magic and humans coexist, some people gain power and do whatever they want. In the end, the evil magicians fight the holy magicians. The good ones win with heavy casualties, and magicians begin to become scarce. My name is Muling, and I was raised with high hopes when I was born, because my grandfather was a survivor of the war, and my parents also had magic power. However, when my grandfather detected my magic power, they found that the magic stone in my body had no magic power fluctuations. However, they did not kill me. Instead, they sent me to a magic academy, hoping that I could be inspired by it. When I went home one day, I accidentally got an ancient magic book, and I slowly reached the peak of my life!
