Zhou Zimo, a "gentle scum" who appears gentle and polite but is actually deeply scheming, makes a living on the streets by cheating and kidnapping. He is well versed in the weaknesses of human nature and is good at weaving lies, but he never thought that he would be "cheated" one day - a thing that calls itself "The Deception System of All Realms" forcibly binds his consciousness and claims to train him to become "the best deceiver in the universe."
But this system is really unreliable: the posted task is to "get three passers-by to treat you to dinner within one day", and the rewards are "beauty filters" and "toilet paper redemption coupons"; the lottery card pool is full of waste props such as "expired coupons", "virtual spicy strips", and "cakes drawn by the boss". What's even more outrageous is that the system also comes with a "reputation value" setting. If the reputation value reaches zero, the system will self-destruct on the spot - and Zhou Zimo found that the initial reputation value of being tricked into this system was a negative number!
In order to save himself, he had to start "daily fraud" - using low-end illusions given by the system to pretend to be pitiful to cheat a meal in the supermarket, performing a "old classmate with amnesia who had his wallet stolen" drama to the owner of the convenience store downstairs, and even pretending to be an astrologer to tell fortunes for rich women in exchange for pocket money.
But who knows, behind this system that seems to be extremely useless, there is a cosmic conspiracy clue hidden behind it: none of its former owners has been able to unbind it alive. And Zhou Zimo is stepping into a super scam weaved by higher-dimensional "liars".
