When the Hongmeng is not judged and the chaos is first opened, the Hongmeng heavens and realms are born, which are divided into thirty-six heavens, seventy-two earth realms, and trillions of mortal realms, with spiritual energy levels decreasing step by step. In ancient times, the heavens and all the ways were perfect, and the six races of immortals, gods, demons, demons, spirits, and humans ruled together. The human race was revered as the "Mother of all the ways" because it possessed the origin of the Hongmeng and all the ways. Several supreme god emperors were born who were in charge of the heavens.
One hundred thousand years ago, a world-destroying catastrophe known as the Twilight of the Gods and the Tribulation of Nirvana of Ten Thousand Daos suddenly broke out. The gods of the thirty-sixth level, headed by the Xuanqiong Heavenly Emperor, coveted the origin of the ten thousand daos in the human race. They tried to refine the entire human race and create the "indestructible Dao Fruit, Eternal Heavenly Dao". They betrayed the alliance and started a war of massacre. Ling Cangsheng, the last heaven-defying divine emperor of the human race, led millions of human monks in a bloody battle for nine days. In the end, at the cost of self-destruction of the emperor's soul, shattering the origin, and shattering the way of heaven, he died together with the gods. He sealed the remnant souls of the gods and the foundation of the false way in the abyss of the heavens, while his fragments of the emperor's soul fell into the mortal world, waiting for rebirth ten thousand years later.
After the catastrophe, the fairy world collapsed, the demon world was shattered, the demon clan retreated to the wilderness, and the spirit clan's bloodline was severed. The human race lost its divine blessing and origin, and was reduced from the supreme being of the heavens to the lowest mortal beings. It was enslaved, slaughtered, and squeezed by the remaining immortal sects, the remaining souls of the demon clan, the beasts of the demon clan, and the powerful families. The path to immortality became extremely difficult with the withering away of all realms, the exhaustion of spiritual energy, and the world has long forgotten the glory of the human race.
