Fantasy: the Immortal Martial Saint Starting from Having Many Children and Many Blessings

Jiang Yuan traveled to a troubled time where demons were rampant and human lives were like a piece of grass. He became an abandoned son of the Jiang family. He was born with insufficient martial arts foundation and his body was corroded by the miasma. He was only twenty years old, but he seemed to be forty or fifty years old. He was about to burp, but he didn't expect to accidentally activate the system of having many children and many blessings. It is better to marry a wife and have concubines than to practice hard for many years. As a result, Jiang Yuan began a crazy journey of marrying wives and concubines, growing up rapidly. Step by step, he became the overlord of the Jiang family and became an immortal martial saint! Many years later, the Jiang family's descendants spread all over the world.
