Code-named "Ghost", he was once a sharp blade that walked in the darkest corners of the world. Now Lu Yuan just wants to run an ancient book restoration shop called "Guan Fuzhai" on the street corner of Canghai City, where he can stay with piles of old papers and smooth out the wrinkles of time with tweezers and brushes.
He thought he had said goodbye to gunfire and intrigue, but trouble always came uninvited.
A seemingly ordinary damaged ancient book reveals a forgotten secret; an unruly and willful rich man has a shocking conspiracy hidden behind him; an unintentional help makes him once again involved in the whirlpool of international power.
When former enemies and comrades-in-arms follow the trail and undercurrents surge under the calm urban life, Lu Yuan discovers that some battlefields can never truly be withdrawn.
The repair tools in his hands can not only bring new life to thousand-year-old scrolls, but can also determine life or death in an instant.
"I'm just a book repairer." Lu Yuan dusted off the dust on his fingertips, his eyes calm and profound, "But whoever wants to destroy my books, or the rules in my eyes, must ask my hand whether I agree or not."
