Many children, many blessings; my family helped me win over the ultimate fairy.

After transmigrating into a world of cultivation, Jiang Yuan found himself reborn as the imperial son of the prestigious Jiang family. Though he inherited none of his parents' extraordinary talents, he awakened a rare fertility constitution, paired with a unique system centered on prosperity through many offspring. The rules were simple: father a child with any female prodigy possessing an aptitude of ninety points or higher, and he would be rewarded with treasures beyond imagination—the Holy Spirit Pill to refine a mortal body into a sacred vessel, the Spirit Ascension Elixir to fortify the physique, supreme imperial-grade weapons, and even the legendary secret medicine of immortality. Finding suitable partners on his own proved far too exhausting, so Jiang Yuan made a pragmatic choice—he handed the system over to his family and let them handle the rest.
