Humans Shrunk 300 Times

Have you ever seen a fly larger than a human?
Have you ever witnessed an ant mightier than a human?
Have you ever encountered a sparrow resembling an ancient colossal beast?
Everything I knew has undergone an earth-shattering transformation!
Ji Chang was at a loss for words on how to describe it, but there was one word that fit most appropriately: immense!
Immense! Tremendously immense! Astonishingly immense! To the extent that even a small blade of grass has turned into a towering tree!
However, the cause behind all these changes wasn't that objects themselves grew larger, but rather Ji Chang discovered that he had become smaller.
Tiny! Incredibly tiny! Unbelievably tiny! So minuscule that even a gentle breeze could send a person soaring through the air!
