If the Top Student Has Hextech, How Can This Tech Tree Be Straight?

Reborn in his high school years, Li Guan finally gets the chance to pursue his true passion for scientific research. However, looking at the Hextech augments refreshing in his mind every week, he finds himself momentarily bewildered. The "Ronin" augment triggers when no one is studying nearby, drastically boosting memory consolidation efficiency. The "Clear Mind" augment slightly enhances focus when his desk is entirely free of clutter. The "Last Stand" augment slightly increases learning efficiency whenever he sits at the very back of the classroom. Something is wrong—twelve out of ten parts wrong. "This system is simply too useful!" "Li Guan, it was just one failed exam, how did you end up like this? You sleep in class and you don't even bring a single book!" "Li Guan, I really misjudged you. I thought we agreed to slack off together, but it turns out you were grinding hard behind our backs. You're no human!" Facing the "respect" and bewilderment of those around him, Li Guan merely smiles, dismissing it all as a gentle breeze.
