Bound to the Top-Ranking System, but Why Am I Backing Up a Superstar?

Li Yihuan suddenly drops dead, only to wake up and discover he has transmigrated to 2013. Armed with his extraordinary vision, he joins FNC, TPA, and SKT in succession, becoming a five-time champion in the dawn of professional League of Legends. Just as Li Yihuan decides to retire at the height of his career, the Superstar Ascension Support System successfully binds to him. "Superstar Ascension Support System successfully bound." "Host, complete the assigned tasks as directed by the System to receive the corresponding rewards." Li Yihuan watches the System keep displaying one bizarre reward after another and slowly types a question mark. He has no time to complain about why the System only showed up when he was about to retire. After all... What do you mean, using a protect-the-carry composition in three straight matches earns me the copyright to a song? What do you mean, playing random champions in ranked and winning ten games in a row earns me mastery of dance? What do you mean, delivering a legendary pre-match speech earns me ten points of favor with a female idol? No! What exactly are you helping me ascend to the top of? And what exactly are you supporting me in? This novel and its characters are entirely fictional. Any resemblance to actual people or events is purely coincidental. Do not imitate.
