Immortal Ruins Demon Fetus Record

In the third year of the Era, the Gods and Demons fought against each other. The Hundred Battles Immortal Lord led the three major clans and fought fiercely with the Demons for three days and three nights, with no outcome in sight. In the end, the Demon Ancestor exhausted all his cultivation and used forbidden power to win. However, he himself had to die. The four elders of the Demon Clan used their souls and secret methods to reincarnate the Demon Ancestor in the Zhang Mansion. This is where the story begins.
