Chuan Shu: I Became the Protagonist of the Eunuch Novel

I've read too many novels, can I still travel through time? Li Yun really traveled through time! He traveled back in time to the novel he just finished reading and became the protagonist's younger brother, an illegitimate child! What? The main character died inexplicably? Well, I'll be the protagonist! I know the distribution of forces, awesome characters, major deeds in the world of cultivation, even where the treasure is hidden, and how to open it! Hahaha, I should be invincible, so excited! However, because of the appearance of Li Yun, the plot became different! And there is also the crisis of annihilation caused by the eunuch in the original novel! How to fix it? No, no, Li Yun must get the plot back on track and proceed in his own way! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
