This Peculiar Way of Reproducing

After overcoming his tribulation and ascending, Fu Chang'an thought he was stepping into the immortal realm, only to end up in another world. The environment was harsh, with yellow sand filling the sky and water more precious than gold! To make matters worse, the world was populated entirely by men, and their method of reproduction was exceptionally unconventional.

At this moment, the original "Fu Chang'an," born into poverty, had been bought by a blacksmith and become the prospective wife of the blacksmith's son. As a man as straight as steel, Fu Chang'an began his journey of self-rescue. But while escaping, he accidentally saved a little boy. He decided to bring him home and raise him as his son. Years later, the little boy had become an exceptionally handsome, towering man who told him in an unquestionable tone, "You're the commander consort I've chosen!"
