The cat unit article contains a lot of cats!
Some plots may not be in line with animal habits, so don't delve into it!
Here is the introduction:
P City is the forefront of the country's economic development. It is small in area but has a large population.
The humans in P City are busy, coming and going. They are on campus during the day, in office buildings at night, and in the 24-hour park. Human beings think that they are the masters of this city. Without them, this city would not exist.
As everyone knows, there is another city under P City. The residents here think that humans are just two-legged beasts that serve them.
They believe that they are the real masters of this city.
