Xuan Shuo was born in the frontier wilderness after the epoch broke. He was neither a hero nor an emperor, but a wandering historian. Using broken ancient books as a boat, he embarked on a journey to find the lost continent "Songyuan". Among the ruins of chaos, Xuan Shuo is not tempted by the power of gold, but only hopes to restore the true past that was obliterated by dust. However, the history of Songyuan is not written by anyone. It weaves a web of lies and uses forgetfulness as a shield. Xuan Shuo confronts mysterious history keepers, exiled old clans, and inheritors of foreign lands. He is both an explorer and a judge. The revelation of every period of history is accompanied by the tearing of faith and identity. He writes on the edge of a dangerous cliff, but gradually discovers that he is also part of the hidden history. This book does not record great achievements and conquests, but how a man fought against the amnesia of the world and used his incomplete pen to reshape the soul of civilization.
