After being heavily wounded on a mission, the dying commander of the special forces Qin Xiao was brought back to the mountain base on the back of a tiger. According to the rumors, that day, it was an extremely beautiful Persian cat that called out the guard soldier and found the commander.

This strange event was transmitted throughout the base, and it became a sensation in the whole place.

After transmigrating into a cat, Bai Xia Xia has been extremely worried. She could understand beast language, eat fruits, and catch fish, but it was useless, her beast friends did not eat cooked food. For half a year, she did not eat a mouthful of cooked meat at all, and everything was so plain that she was going crazy.

She deliberated and pondered, thinking seriously about Cat’s remaining life—being a house cat is good, there will be a poop shovel officer (a pet owner) to serve me. A suitable poop shovel officer was not easy to find, living conditions were not guaranteed, and the risk of becoming a stray cat was high.

Therefore, she found an iron rice bowl (a lifetime employment), working for her home country (in a governmental position).
