After Being Burned by the Sky, I Want to Burn the Sky

Ah, this is my first time trying to write a novel. I have to make up a hundred words for the introduction. What should I do? The novel is a very ordinary novice fantasy novel, and I don't know what to say in the introduction. The novel is rebirth. The past and present life will be gradually revealed to everyone and the truth will be revealed. Actually, what should I do if I don't write too many words at the moment? I'm a little panicked, but I don't care about my grades. After all, it's my hobby. Will I be scolded if I update my luck? This is a novel I conceived when I was in high school. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
