In modern times, Lin Yan, a graduate student in archeology, unearthed an ancient bronze mirror from a prehistoric site about 12,000 years ago during an archaeological excavation in northwest China. The moment the mirror was unearthed, strange phenomena suddenly occurred: thunder in the clear sky, crazy compass rotation, and all the electromagnetic waves around the ruins were chaotic.
When Lin Yan touched the mirror, a torrent of information poured into his mind. He saw the destruction of the Emperor's civilization, saw the origin of Xuanjian, and heard a sentence:
"The way of heaven circulates, and civilization has calamities. When Xuanjian is born, calamity is coming. Those who have learned from it should continue the light of civilization with compassion."
Since then, Lin Yan's life has completely changed. He discovered that the complete metaphysical knowledge system of the Emperor's civilization was sealed in the Xuanjian: from the most basic heavenly stems and earthly branches and the five elements to the most profound Qimen Dunjia and Neidan Taoism. This knowledge is not instilled out of thin air, but requires him to learn, comprehend, and practice step by step to unlock it.
At the same time, a mysterious force "Guixuhui" that has been secretly tracking Xuanjian for thousands of years also surfaced. They are a lineage that fell when the Emperor's civilization was destroyed. They believe that the destruction of civilization is inevitable, and try to accelerate the collapse of contemporary civilization and establish a "new order" ruled by them on the ruins.
Purpose: Today's scientific community generally believes that earth's civilization only has a written history of several thousand years, and that the age of the universe is about 13.8 Billion years. However, "Tianyan Xuanjian" puts forward a subversive setting: the earth has existed for far longer than scientific knowledge.
