The College Entrance Exam Is Almost Here, and You Want Me to Save the World?

[A Hundred Days to Save the World + Knowledge Is Power + Ensemble Cast + Apocalypse + Student Exams]

During a placement test, tentacles covered in eyes suddenly dangle from the ceiling. I'm the only one in class who can see them devouring my classmates' "orbs of knowledge." As I tremble with fear, a cold voice rings out in my mind:

[Knowledge Is Power System activated. Civilization-level threat detected.]

[The Knowledge Devourers will completely replace humanity in 100 days.]

[Warning: The day of the college entrance exam will be the end of civilization.]

I stare at the homeroom teacher's claws as she grades our papers.

Wiping away my cold sweat, I write the first answer on my math test.

After all, getting into a good university is the first step to saving the world.
