The protagonist, Geng Zhi, is a "useless" inventor who is obsessed with solving trivial daily problems. He is famous on the Internet as "Handmade Geng ProMax". He seriously invented a series of inventions that were ridiculed by netizens, such as the "automatic foot-washing and bathing all-in-one machine", the "portable air conditioner the size of a Coke can", and the "perpetual BBQ machine". However, what he and everyone else did not know was that his invention inadvertently touched and distorted the rules of the multi-dimensional world in terms of the underlying logic of physics. When the "accurate pourer for soy sauce bottles" he invented in order to "never waste a drop of soy sauce" accidentally opened a stable passage to the "condiment dimension", a storm began that swept through countless dimensions.
