In the world of cultivation, marriage, pregnancy, and childbirth are practically a death sentence. A cultivator's time is better spent pursuing immortality than raising a family.

At least, that's what everyone else believes.

Yoo Seojin, reincarnated with the worst spiritual root imaginable, discovers a rather unusual system after getting married: the Family Patriarch Simulator.

While other cultivators seek enlightenment through orthodox methods, Seojin follows a different path. Through marriage and childbirth, he can obtain children of varying ranks, earn rewards, and steadily strengthen himself.

An EX-rank child? A jackpot.

An N-rank child?

"Another dud."

For Seojin, building a family isn't a distraction from the path to immortality. It's the cultivation method that might finally get him there.
