Among the Yanluo Clan, "Yan" was the number one surname. It represented the noblest bloodline and had the strongest inheritance.
However, those with the Yan surname were divided into two lines of descent and thirteen gods.
The so-called two lineages were known as the Yan Family of Yama and the Yan Family of Trayastrimsa.
The thirteen gods referred to the other thirteen Yan Families that had given birth to gods. Because they lived in different places to cultivate and their ancestors had different inheritances, they became thirteen relatively independent forces.
Although their strength was far from that of the two-line of descent, they had many clansmen and became an important part of the Yan Family.
