The No. 07 base where I am located is the core of the factory and also the place where I was born. It is well-equipped with 128 dormitories, integrating entertainment venues, shopping malls, schools, hospitals, training grounds, sperm extraction fields, laboratories and gyms, so that the elite bulls can live in a carefree environment. All of this is to ensure the highest quality of semen and provide vital energy elements for fighting against the Hai. In addition, the elite bulls will mate in the base, donate excellent genes to new soldiers, and cultivate the next generation of stronger warriors.

I am number #0402, this is my starting point and my battlefield. The base not only gave birth to my body, but also witnessed the bond and growth between me and the fourth class of elite bulls. We tried our best on this land and used our semen to inject hope into the continuation of the furry civilization.

The furry civilization was facing the destructive invasion of the Hai their cell tissues were almost indestructible, until the birth of the energy core that changed everything. And the birthplace of the energy element is this huge elite bull factory.

This is the story of how I became the most productive sperm bull.
