Many children bring many blessings; my master's wife is forcing me to marry nine of my senior s

Transmigrating to a cultivation world, Zhou Tian becomes the tenth disciple of the Tai Xuan Sword Sect. He awakens the "Many Children, Many Blessings" system, allowing him to grow stronger simply by marrying and having children. However, the Tai Xuan Sword Sect's enemies arrive unexpectedly, the sect leader perishes on the spot, his body and soul annihilated, and countless disciples die, rendering the sect virtually defunct! Besides his master's wife, Zhou Tian only has nine senior sisters left. One day, his master's wife calls Zhou Tian before her, points to the nine senior sisters beside her, and solemnly says, "To revitalize the sect, you must choose one of your senior sisters as your Daoist partner." Looking at his still-attractive master's wife and the nine stunningly beautiful senior sisters, Zhou Tian can't help but swallow hard. Zhou Tian: "I... can I choose them all?" Master's wife: ??? Nine senior sisters: ???
