The Rebirth of Me in the Romance of the Three Kingdoms Zhang Jiao

I am a middle school student who likes to read the Romance of the Three Kingdoms. Although I like to read classics, my grades are very poor. Until one day, my destiny changes. It was a stormy night. I was reading a book with headphones on, and what I was reading was The Romance of the Three Kingdoms. Suddenly my vision went dark and I heard a mechanical voice coming from my ears: "Ding dong... I have defined the role for the host and started to travel." Just like that, I started a magical journey. The first book of a newcomer is not well written. Please give me some advice. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
