Zan Yunxiao was an ordinary man from a modern world, until a sudden twist of fate dragged his soul into a vast cultivation realm where strength decides destiny and immortals walk above mortals. Upon awakening, he discovers he has been bound to a mysterious System unlike any other. This System does not reward battle victories. Instead, its sole directive is unusual and absurd in the eyes of cultivators: produce offspring and expand a lineage. At first, Zan Yunxiao dismisses it as a joke of fate. But soon, he realizes the System’s rewards are real, granting him cultivation boosts, rare techniques, and even heavenly treasures whenever his descendants are born or he complete a system mission.
