After a mysterious flash of light, the IQs of adults around the world collectively dropped to the level of a five-year-old. The world instantly degenerated from a civilized society into a super-large, highly destructive kindergarten.
Lin Ming, a social animal, inexplicably became the only "survivor" of this outrageous change - the last sane adult in the world.
Now, the KPI he faces is no longer the boss's needs, but: how to use bubble machines and candies to establish a new order in the "paradise"? How to prevent a former bank manager from smashing a flower bed with a dumbbell? How to lead a group of "big babies" who cry for stickers to survive in the ruins of civilization and find out the truth of this ridiculous incident?
This is a hilarious daily routine of raising children around the world, as well as a lonely journey to protect a fragile civilization. Welcome to the outrageous world of World's Only Guardian!
