This matter all started because of Li Shuangxi.
After Mrs. Li died on the escape route from famine, Old Master Li feared he too would die on the road, so he sexually abused all of the unmarried maids in the Li Family.
Li Shuangxi was able to escape misfortune because of Li Daxi.
After knowing Old Master Li's intentions, Li Daxi found a fortune-teller among the fleeing refugees, provided him with food and water, and had him tell Old Master Li that Li Shuangxi and he were dragon and phoenix twins with deep blessings, and were celestial children descended from heaven. As long as they remained virgins, they could protect the people around them as well as the Li Family.
The fortune-teller also exaggerated some dangerous incidents that the Li Family encountered on the escape route, adding fuel to the fire: "Old Master Li, your family's escape from these calamities was all thanks to the efforts of the Li Shuangxi siblings."
