The second day after he finished spending all his wealth on the Book of Eon, Zong Shou was like a human puppet, letting people do what they wanted with him.
Bathing and changing clothes. Wearing a red robe and being brought out of the city to pick up his wife. The couple went onto the sky altar to worship the heavens and pray for Gantian Mountain, officially establishing the country. Then telling the heavens that Xuanyuan Yiren and him were going to be married.
In the ancient world, a country's ruler was seen as a dragon and the high officials as flood dragons, they all received the missions of heaven and were the sons of heaven.
Thus rulers all saw the heavens as their father, and they obviously had to tell their father about their marriages and so forth.
