Thirty years ago, a dense fog descended from the sky, blotting out the heavens and the sun.
Countless abominations burst from the fog.
The apocalypse arrived. Abominations ran rampant, history was severed, and humanity fought desperately against them with the technology and courage it had left.
The flame of civilization was about to die out.
Then, one day, an unknown subway appeared without warning, bringing a bridge to other worlds.
The pioneers of Huaxia found a power to fight the abominations in those other worlds: the Six Arts of the Gentleman.
Rites, music, archery, charioteering, calligraphy, and mathematics.
Each art corresponded to a profession.
Countless professionals rose to meet the calamity, forcefully halting the abominations' advance.
At last, humanity was able to catch its breath.
Lu Chen had arrived here three years ago.
On his very first day, he awakened the Historian profession, stunning the entire school.
