The reason why heaven and earth can be long-lasting is because they do not generate themselves, so they can live forever.
In the past, when the world first opened, there were only two brothers and sisters, Nuwa, in the Kunlun Mountains, and there were no people in the world. Nuwa created humans from the nirvana and opened up human wisdom. Later, she refined five-color stones to mend the sky, cut off the Ao and stood on the four poles, killed the black dragon to help Jizhou, accumulated reed ashes to stop the floods, and people lived in peace and contentment.
Cold comes and summer comes, autumn harvests and winter hides, dynasties change, and troubled times come again. The world is in chaos, evildoers and monsters emerge from time to time, and all living beings suffer from the troubled times and are persecuted by demons and monsters, suffering unspeakably.

Under the leadership of the Fengdu sect, cultivators in the human world were slaying demons and killings everywhere. The vitality of the demon world was greatly damaged, and the world was temporarily stable.
A man of righteousness, in order to eradicate the evil and eliminate future troubles forever, captured the demon king and sealed it on the shore of the East China Sea. Before the Demon King Fenghun was captured, he looked up to the sky and screamed, "Today I will be destroyed, and tomorrow I will be destroyed!" The righteous people were all frightened and suppressed Wutian in Kunlun.

Suddenly a thousand years have passed, and the fiery red teardrop has absorbed the essence of the world and is full of spiritual energy.
