The Flash of Genius in the Magic Academy

Bai Liuxue accidentally traveled to the game "Etru World" that he was obsessed with, but found that he had become a supporting character who was supposed to be cannon fodder in the plot, an ordinary young man at Stella Magic Academy. With a pair of "brown-eared duck glasses" that can spy on the rules of the world, he is familiar with every hidden mission, the fate of every character, and even knows the "pseudo ending" in which the world will eventually be destroyed. Carrying a "body that leaks magic power", his magic power is as difficult to condense as a funnel, but he has gained the power of "flash" that grows infinitely, teleporting with one step and living and dying with a single thought. However, the "narrative power" of the game is like an invisible shackle, which prohibits him from revealing the identity of the time traveler. He can only use obscure intervention to leverage the plot: saving an ally who is destined to die, intercepting the opportunity of a genius, and even dancing with a future villain... Stella Academy of Magic gathers elites, where arrogant nobles, genius mages, and mysterious native characters are all intertwined. Bai Liuxue is walking on thin ice: he must use game knowledge disguised as "lucky intuition" to survive in a low-key manner in classroom duels, underground explorations and political whirlpools, while secretly pursuing clues to the "true ending" that only he knows, a secret that may reshape the world order. However, every intervention he makes triggers a chain reaction: characters who were supposed to die become allies, the original hero falls into darkness, and the will of the world seems to be gradually awakening to his "cheating"... Can Bai Liuxue find a way back before the plot collapses? Or is he the last missing piece of the puzzle in the "true ending"?
