Deep in Qingteng Lane in the old city, there is an ancient book restoration studio called "Yanxin Pavilion". Lin Yan, the 26-year-old manager, is surrounded by yellowed pages and mottled ink every day. With his fingertips, he can revive broken ancient books. He is thin and reserved, like the old locust tree in the alley, silently rooted in his own little world, with only a calico cat named "Mo Mo" as his companion.
No one knows that this young craftsman, who doesn't even know how to use a smartphone, was once the "Inkstone Keeper"—a group of secret inheritors who repaired ancient artifacts with energy marks for "special groups." Lin Yan himself also has a hidden ability: when he touches certain old objects, his fingertips will become numb, and fragments of images that do not belong to him will flash before his eyes.
He originally wanted to live a stable life in the studio left by his grandfather, but during an antique theft case, he was dragged into the whirlpool by Su Wan, a journalist who ran social news. The stolen ancient jade conceals the energy fluctuations of superpowers. Collector Zhao Chengze, who covets this power, is pressing harder and harder, and even involves his neighbor Lao Zhou who runs a cafe.
When the peace was broken, and when the responsibility of "Yan Yan keeper" came to the eyes from his grandfather's letters, Lin Yan had to face his own "specialness". He used the meticulousness to restore ancient books to piece together the truth, and used the stubbornness in his bones to protect the people around him. He blazed his own path between the ordinary city and the hidden supernatural world.
This is a story about inheritance and protection, and also the growth process of an ordinary person gradually seeing himself clearly and grasping the edge in the torrent.
