According to the brief introduction to different time and space in the "Basic Rules for Beginners" of Space and Time Law Enforcement Officers, there are five different time and spaces within the same Earth's magnetosphere. They are: Spade, Heart, Club, Diamond and Joker. The level of scientific and technological development in the five time-spaces is uneven, and the humanities and living habits are also very different. At first, people in a certain time and space did not know the existence of other time and space.
However, due to various reasons, on a certain day of a certain year, space-time cracks of varying sizes began to appear in various places in various time and space. People in different time and space can pass through the space-time cracks and travel to other time and space, seriously destroying the order of time and space. Therefore, Joker, the most powerful among the five time and space, established a mysterious organization - the Time and Space Alliance. This mysterious organization exists to train time and space law enforcement personnel.
The "Law Enforcement Rules" for time and space law enforcement officers stipulates that time and space law enforcement officers are responsible for repairing cracks in time and space and expelling external space and time intruders.
The story takes place in the life of a young law enforcement officer in time and space, but is this a beautiful entanglement of love and hate across time and space, or is it an unknown trap? Is it really the power of God that allows me to travel through time and space and bring me to you?
