Everyone Shrinks: Starting at 1.75 Centimeters

[All-out war + reborn in the apocalypse + shrunk to one-hundredth size + beautiful school belle + evolution and upgrades + humans and beasts fighting to survive + shifting civilizations] Humanity is about to shrink to one-hundredth of its size. Ants become giant beasts, and the sports field turns into hell! Ye Jun, a reborn survivor, grabs the principal's microphone and screams a warning, but everyone thinks he's crazy. Only the class monitor, Qin Shiyu, follows him into the infirmary where they find a staple spear capable of slaying gods, a drip-filter water bottle system, and an evolution gem that can temporarily turn them into giants! As hypocritical teachers build a kingdom of slaves and a cockroach queen devours the campus, Ye Jun takes the school belle by the hand, treads over corpses, and raises an ark for a miniature civilization. The battle to conquer this apocalyptic world is about to begin!
