Heaven's Chosen Empress or Little Underdog? Then I'll Steal Her Fate

Good news: I transmigrated into a book, into the world of a fantasy novel! Bad news: My name is actually Wang Teng?! Good news: This novel is not A Leaf Veils the Heavens! Bad news: I have no idea how many fantasy novels this vast world is made up of. Wang Teng transmigrated into a book and became an insignificant passerby destined to be cannon fodder in a fantasy novel. He discovers that he can see characters' halos and past experiences! [Servant Disciple Zhang Yong, a pure-white passerby halo. Today, he left the city to gather herbs and discovered a nightshade flower in a cave!] A nightshade flower? Not bad, not bad! Then I will intercept it! Hand it over! [Outer Sect Disciple Li Peng, a light-blue supporting-character halo. Tomorrow night, while practicing at home, he will discover a Soul-Cleansing Pill hidden in his house!] A Soul-Cleansing Pill! What a treasure! I will intercept it too! Hand it over! [Inner Sect Disciple Ye Fan, a crimson protagonist halo! In ten days, he will go out to train and obtain a great fortune and a heaven-defying opportunity!] A great fortune? A heaven-defying opportunity? You think I will let you have it? I will intercept them all! Hand them over! [He picked up the pitiful Lin Youchu, who has a dazzling-gold destiny halo! The reincarnation of an empress! Blessed with heavenly fortune!] Huh? The destined empress is still a pitiful little waif? Hand it over... Why are you so soft?
