[Many children, many blessings] + [Multiple female leads] + [Fantasy] + [Harmonious family]
Jiang Yuan transmigrated to a fantasy world and became the imperial son of the Jiang family. He did not inherit the talents of his imperial parents, but he awakened a natural fertility body and a system that brings many children and much happiness!
As long as you give birth to a child with a female prodigy whose aptitude exceeds 90 points, you can obtain the Holy Spirit Pill that transforms a mortal body into a holy body, the Spirit Ascension Pill that enhances physical constitution, the ultimate imperial weapon, and the secret medicine for immortality...
