Shinshin Dogen

At the beginning of chaos, the universe was divided into four major divine realms. The first realm was controlled by the Eastern God. The supreme god of the first realm was called the Yuanshi God. The second domain is governed by the Western God, and the highest God is called the Xuantian God. The Third God Realm and the Fourth God Realm are called the Demon God Realm and are respectively controlled by the Eastern Demon God Tianji Demon Lord and the Western Demon God Blood Moon Demon Lord. In order to make the universe more peaceful, the Eastern Gods united with the Western Gods to fight against the Eastern Demon God and the Western Demon God.
