On October 17, 2025, comet 3I passed by the earth, and the laws of physics were completely rewritten.
All human beings have shrunk 100 times to a body of 1.7 Centimeters, and have to face the original size of the campus: cockroaches have become man-eating monsters, a drop of rain can be a world-destroying flood, and 30% of human beings have mutated into micro-zombies, wandering in the ruins.
Chen Yebai, a top student in the Department of Physics, calculated the survival formula for the new world at the moment of change: the power-to-weight ratio increased by 100 times, surface tension became a deadly weapon, and sound propagation was no longer a secret——
When former classmates turn into zombies and attack, when the basketball court turns into a desert thousands of miles away, when an ant can trample the shelter, Chen Yebai clenches the ballpoint pen spear in his hand and reconstructs human civilization under the shadow of the giant.
But he soon discovered that the real threat was not zombies or giant insects, but those who survived like him——
And deep in the campus, those "gods" who still maintain normal sizes.
A small body, surrounded by giants.
When humans become ants, who will remember that we once dominated the earth?
