The First Ancestor of All Time

This is an incredible world, a sea of ​​stars with no end, no length and no width. There are endless stars floating on the ocean, islands comparable to the world, and sea beasts bigger than the world. This is a world tree rooted in the sea of stars whose height and width are unknown. The World Tree gives birth to the world by itself. One flower on the World Tree is a world, one leaf is a world, and a fruit is a world. Xia Yibai, a fruit on the World Tree, is a pure-blood son of the Xia God Clan in the world called Yanling World. He was born with pure blood, but his wings were broken when he was in the sky. After three years of trough, he came back from Nirvana, killed all the gods with swords, and burned the heavens. After experiencing this magical and vast world, he became the first ancestor in all eternity.
