Preface: It is said that tens of thousands of years ago, "the sky and the earth were as chaotic as chicken eggs, and Pangu was born in it. Eighteen thousand years ago, the sky and the earth opened up, and the clear Yang was the sky, and the turbid cloud was the earth. Pangu was in it. Nine changes a day. God is in the sky. Holy in the earth. The sky is ten feet taller. The earth is ten feet thicker every day. Pangu is ten feet longer each day. So 8,000 years old. The number of days is extremely high. The number of earth is extremely deep. Pangu is extremely long. Therefore, the sky is ninety thousand miles away from the earth. After that, there are three emperors."
The heaven and earth are divided into two, and the goddess of creation reincarnates all things. From then on, the world of heaven, the world of man, and the world of earth began to take shape.
At the beginning of the Three Realms, the heavenly realm became a place where the immortal family was entrenched due to its rich resources and abundant spiritual energy. The human world is rich in materials, but lacking in spiritual energy. It has become a place where mortals live, and their lifespan is only a few decades. However, the earth realm has scarce resources and insufficient spiritual energy, and has gradually become a place where the immortal and mortal realms are expelled, thus giving rise to the three races of demons, devils and ghosts.
