Fantasy: Compare backgrounds? Worthy?

Sinopsis

I can't believe I've transmigrated into the novel I've been obsessed with— and even become a cannon fodder with a tragic end! Luckily, I've been bound to a system. With just one click, I can add buffs, and I can make up any overpowered background I want! This time, watch me rewrite my fate, turn the tide, take down scumbags, slap faces, and ascend to godhood all the way!
